Subject: [PATCH 001/139] fix(frontend): resolve the refractor chunk failure
 that remounts the playground and closes the Advanced drawer

The production webpack build stubbed out react-syntax-highlighter's dynamic
import of refractor/all via an IgnorePlugin. When the agent chat markdown
renderer (AgentChatSlice/assets/markdown.tsx, PrismAsync) highlighted a fenced
code block, that ignored chunk threw "Cannot find module 'refractor/all'",
tripping the Layout error boundary and remounting the playground subtree, which
unmounted the open Advanced drawer.

refractor@5 is installed and resolves every subpath rsh imports (all 297
languages plus /all and /core), so the ignore was stale and purely harmful.
Remove it so the chunk loads.

Subject: [PATCH 005/139] chore(frontend): exclude tests from app tsconfigs

The playwright suites are owned and type-checked by the tests workspace,
which holds the @playwright/test dependency; tests/manual scripts import
state modules that no longer exist.

 imports

- Restore Parameter, CorrectAnswer and _EvaluationScenario to lib/Types.ts
  (removed by cleanup while consumers remained)
- Re-export MetricColumnDefinition from the EvalRunDetails table barrel
- TooltipButtonProps was renamed EnhancedButtonProps; statusMap moved to
  @agenta/entity-ui/variant
- Synthesize full Parameter objects in UseApiContent

Subject: [PATCH 007/139] fix(frontend): resolve high-count tsc error clusters

- useRunMetricData: type selection as the unwrapped value, not the atom
- Webhook builders: narrow WebhookFormValues union before field access
- filtersAtom: accept updater functions in the write signature
- Organization settings: drop stale react-query v4 useErrorBoundary and
  migrate setQueriesData to the v5 filters shape
- evaluations/utils: surface variantId from invocation metadata
- PreviewTableRow: add index signature required by InfiniteTableRowBase

+# TSC Error Inventory — OSS + EE apps
+
+Generated 2026-07-22 from `pnpm --filter @agenta/oss exec tsc --noEmit` and
+`pnpm --filter @agenta/ee exec tsc --noEmit` (worktree `upbeat-shannon-c6fee8`, clean tree).
+
+## Headline numbers
+
+| App | Baseline | After quick-win pass (2026-07-22) |
+| --- | --- | --- |
+| OSS | 591 | **422** |
+| EE  | 525 | **391** |
+
+Quick wins QW1–QW3 and QW5–QW10 are DONE (QW4 TraceSpanNode deferred — see below).
+Fixing exports also *surfaced* some previously-masked drift (broken imports resolve as
+error-types that suppress downstream checks), so the net is smaller than the sum of
+cluster sizes; the surfaced errors are real and belong to the medium clusters.
+
+| App | Errors (baseline) | Notes |
+| --- | --- | --- |
+| OSS | **591** | 532 in `src/`, 56 in `tests/`, 3 elsewhere |
+| EE  | **525** | **485 of these are shared `../oss/src` files** — duplicates of OSS errors |
+| EE-only (files under `ee/src` + ee test fixtures) | **~40** | Billing page is the main hotspot |
+
+**Effective unique universe ≈ 630 errors.** Fixing an OSS-side error usually removes it
+from both columns, so all prioritization below is done on the OSS list.
+
+## By error code (OSS)
+
+| Code | Count | Meaning |
+| --- | --- | --- |
+| TS2339 | 150 | Property does not exist on type |
+| TS2322 | 123 | Type not assignable |
+| TS2345 | 88 | Bad argument type |
+| TS7006 | 47 | Implicit `any` parameter |
+| TS2353 | 27 | Unknown property in object literal |
+| TS2307 | 19 | Cannot find module |
+| TS18046 | 18 | Value is of type `unknown` |
+| TS2554/2769/2344/2304/2305 | ~50 | Arity, overload, constraint, missing name/export |
+| rest | ~70 | long tail |
+
+## Hotspot directories (OSS)
+
+| Directory | Errors |
+| --- | --- |
+| `src/components/EvalRunDetails` | 190 |
+| `src/components/pages` (observability, settings, overview, evaluations) | 78 |
+| `src/components/SharedDrawers` | 53 |
+| `tests/` (playwright + manual) | 56 |
+| `src/components/Webhooks` | 18 |
+| `src/components/Playground` | 17 |
+| `src/components/EvaluationRunsTablePOC` | 16 |
+

+
+## Quick wins (one fix → many errors)
+
+Ordered by errors-killed-per-unit-of-work. The first two are config/dep-level and kill ~80
+errors across both apps without touching product code.
+
+### QW1 — Exclude/delete stale `tests/manual/datalayer` scripts (~25 errors)
+`oss/tests/manual/datalayer/test-apps.ts` (18 errs) and `test-observability.ts` (6 errs)
+import modules that no longer exist (`src/state/newApps/*`, `src/state/app/atoms/fetcher`,
+`src/state/newObservability/atoms/queries` — verified gone). These are dead manual scripts.
+**Fix:** delete them, or add `tests/manual` to `oss/tsconfig.json` `exclude`.
+
+### QW2 — `@playwright/test` unresolvable from OSS tsconfig (~9 direct + cascade)
+`oss/tsconfig.json` includes `**/*.ts`, which pulls in `oss/tests/playwright/**`, but
+`@playwright/test` is only a dependency of the `tests` workspace, not `@agenta/oss`.
+Every playwright file then also produces downstream TS7006/TS2304 noise (~31 errors total
+in `tests/playwright`). **Fix (choose one):** exclude `tests` from the app tsconfig (the
+`tests` workspace has its own), or add `@playwright/test` as an OSS devDependency.
+
+### QW3 — `RunLevelMetricSelection` atom vs value mixup (~27 errors)
+`EvalRunDetails/components/views/OverviewView/*` (BaseRunMetricsSection,
+MetadataSummaryTable, OverviewSpiderChart, OverviewMetricComparison, useRunMetricData)
+access `.stats`/`.state` directly on `Atom<RunLevelMetricSelection>` — the selection is
+passed around as an atom in the type but consumed as a plain value (or vice versa).
+One type/unwrap decision in the shared hook/atom kills all 27.
+
+### QW4 — Duplicate `TraceSpanNode` type (16 errors) — DEFERRED, not actually quick
+Two incompatible `TraceSpanNode` definitions coexist:
+`packages/agenta-entities/src/trace/core/schema` vs `oss/src/services/tracing/types`.
+Investigation showed the divergence runs through the whole `TraceSpan` base: OSS uses TS
+enums (`TraceType.INVOCATION`) where entities uses zod string-literal unions, and entities
+is `| null` everywhere OSS is `undefined`-only. Aliasing the OSS type to the entities type
+would break every `=== TraceType.X` comparison (TS2367) in OSS consumers. Needs a focused
+boundary refactor: re-export entities types from `oss/src/services/tracing/types`, replace
+OSS enum value-usages with the entities enum objects (`TraceTypeEnum.enum.invocation`) or
+plain literals, then delete the local interfaces.
+
+### QW5 — `WebhookFormValues` missing fields (~16 errors)
+`Webhooks/utils/buildSubscription.ts` + `buildPreviewRequest.ts` read 8 properties
+(`url`, `auth_mode`, `auth_value`, `github_pat`, `github_repo`, `github_branch`,
+`github_workflow`, `github_sub_type`) that aren't on `WebhookFormValues`. Adding the
+fields to the interface (they're clearly real form fields) clears all of them.
+
+### QW6 — `setFilters` doesn't accept an updater function (~16 errors)
+`ObservabilityHeader/index.tsx` calls `setFilters((prev) => …)` 4× but the setter is
+typed `(filters: Filter[]) => void`. Each call site yields 1× TS2345 + 2–3× TS7006.
+**Fix:** widen the setter type to `SetStateAction<Filter[]>` (it's almost certainly a
+jotai/useState-backed setter) — one signature change kills 16.
+
+### QW7 — react-query v5 leftovers in Organization settings (~6 errors)
+`pages/settings/Organization/index.tsx`: 4× `useErrorBoundary` (renamed to
+`throwOnError` in v5) + `string[]` passed where `QueryFilters` expected. Mechanical
+v4→v5 migration of one file (13 errors in the file total).
+
+### QW8 — Missing exports, 4 symbols (~16 errors)
+- `MetricColumnDefinition` not exported from `EvalRunDetails/atoms/table` (4 errs)
+- `Parameter` and `_EvaluationScenario` gone from `@/oss/lib/Types` (4 errs)
+- `GenerationChatRow`/`GenerationInputRow` not exported from Playground state types (4 errs, tests)
+- `TooltipButtonProps` / `statusMap` default-vs-named export confusion (2 errs)
+Each is a one-line export (or an import-style fix at the call sites).
+
+### QW9 — URL params type missing `variantId` (~9 errors)
+`References/cells/*`, `EvaluationRunsTablePOC/export/referenceResolvers.ts` read
+`variantId` off a URL-params object typed without it (`appId/revisionId/variantName/…`).
+One field added to the params type in `src/state/url` clears 9.
+
+### QW10 — `PreviewTableRow` doesn't satisfy `InfiniteTableRowBase` (~11 errors)
+6× TS2344 + 5× TS2322 in EvalRunDetails table/query atoms trace to one constraint
+mismatch. Fix the row type once (likely a missing `id`/index-signature member).
+
+**Quick-win subtotal: ~150 of 591 OSS errors (and their ~120 EE duplicates) from ~10 targeted fixes.**
+
+---
+
+## Medium-effort clusters (real code drift, needs a bit of thought)
+
+- **EvalRunDetails remainder (~100 errs after QW3/8/10):** the largest concentration;
+  `Table.tsx`, `FocusDrawer(+Header)`, `EvaluatorMetricsChart/BarChart`, `ScenarioNavigator`,
+  `ConfigurationView/EvaluatorSection`, `atoms/query.ts`, `runMetrics.ts`. Mix of
+  TS2339/TS2322 from evolving run/metric entity types. Best attacked per-file after the
+  atom-level quick wins land, since many will collapse.
+- **SharedDrawers remainder (~35 errs after QW4):** AnnotateDrawer transforms treat JSON
+  schema values as `{}` (`.type`, `.anyOf` on `{}` — needs a proper JSONSchema type);
+  AddToTestsetDrawer drawer-state typing; tracing store `discard` API drift.
+- **Observability pages (~35 errs after QW6):** `getObservabilityColumns`, tracing
+  selectors, `usePostAuthRedirect` (7 errs — `unknown`-typed org/app data, TS18046
+  cluster: `result`/`compatibleOrgs`/`appsData` need typed fetchers).
+- **`state/url/playground.ts` (7)** + **`newObservability/selectors/tracing.ts` (7)**.
+- **EE Billing (`ee/src/.../settings/Billing/index.tsx`, 7 + modal 1):** the only
+  EE-app hotspot.
+
+## Long tail / mechanical sweeps
+
+- **TS7006 implicit `any` (47):** parameter annotations; many disappear with QW2/QW6.
+- **TS2322 `string | undefined` → `string` (11):** add guards/defaults at call sites.
+- **TS18046 `unknown` (18):** type the fetch/query results instead of casting.
+- **EE test fixtures (~25 errs):** `oss/tests/playwright/acceptance/*` + `tests/tests/fixtures`
+  — same root cause as QW2 (test workspace types leaking into app tsconfig).
+
+## Suggested attack order
+
+1. QW1 + QW2 (config only, −80 errors, zero product risk)
+2. QW3–QW10 (−~130 more, each an isolated PR-able fix)
+3. Re-run tsc, re-inventory EvalRunDetails — expect it to shrink well below 100
+4. Then the per-file medium clusters, EvalRunDetails first (biggest, and shared with EE)
+
+Raw outputs preserved at scratchpad `tsc-oss.txt` / `tsc-ee.txt` for this session.

Subject: [PATCH 009/139] fix(frontend): type-check EvalRunDetails layer; oss
 tsc 422->347

Mirrors the vetted WP-4e-2a in-place fixes from fe-chore/move-evals-to-packages
(adapted to OSS import paths) plus new fixes for the component layer:

- restore PreviewTestCase to lib/Types; re-export MetricProcessor/MetricScope
- add "input" to EvaluationColumnKind (backend mapping emits it) and type the
  visibility-label column extension in buildPreviewColumns
- recharts v3 API drift in EvaluatorMetricsChart (TooltipContentProps, tuple
  radius, MetricStripEntry contextual typing)
- widen evaluationType to EvaluationRunKind; type query atoms as nullable
- latent runtime bugs typed as-is per WP-4e-2a convention (applyAggregatesToRaw,
  metricProcessor ReferenceErrors, dead metric-group branches) - flagged, not fixed

Subject: [PATCH 010/139] fix(entities,entity-ui): updater-style refresh atom
 and optional variant id

- createPaginatedEntityStore: refreshAtom/actions.refresh accept an optional
  value or updater (bare set() still bumps the counter) - clears the
  'Expected 0 arguments' cluster across testset modals and other consumers
- EnvironmentStatus: variant.id optional; the component already guards it

Subject: [PATCH 011/139] fix(frontend): type-check observability, drawers,
 playground, onboarding layers; oss tsc 347->105

Parallel per-area pass, behavior-preserving throughout (latent runtime bugs are
typed as-is with NOTE comments per the WP-4e-2a convention, not silently fixed):

- TraceSpanNode OSS<->entities dual-type: aligned at every crossing with
  documented boundary casts (16 errors -> 0); annotations field added to the
  OSS node (drawer stores attach it at runtime)
- SharedDrawers: broken SessionDrawerButton imports repaired, JSON-schema
  access typed, null-safety in SelectEvaluators/AnnotateDrawer, drawer
  payload/ref/label types aligned with runtime
- observability: extended-column types for custom antd props, TraceRow/
  SessionRow InfiniteTableRowBase conformance, traceTabsAtom updater support,
  ag-attributes selector typing at the producer
- playground/url-state: removed drifted local duplicates of package types,
  eagerAtom->atom where deps are sync, modal/store prop alignment
- onboarding/testsets/org: updater-widened widget UI atom, tour placement
  vocabulary fix, OnboardingLoader next/dynamic compat, org provider API
  types matched to the backend wire shape (settings/flags dicts)
- EvalRunDetails remainder: WP-4e-2a-vetted atom fixes adapted, recharts v3
  formatter/content signatures, stale import paths repointed

Flagged for triage (typed as-is): AddToTestsetDrawer trace draft discard/
update call missing molecule actions; orphaned SessionDrawerButton

Subject: [PATCH 013/139] fix(frontend): type-check InfiniteVirtualTable root +
 cross-cutting patterns; oss tsc 105->82

- InfiniteVirtualTable: canonical ExtendedColumnType exported from the barrel
  (three local extended-column copies repointed as aliases); pure read fn for
  columnHiddenKeys (write path reconciles versions); memo generic preservation;
  onRow/getRowProps/rowSelection.fixed aligned with antd 6
- antd v6 PopoverStylesType 'body' drops typed as-is (2 sites, existing pattern)
- React 19: JSX.Element -> ReactElement in RequireWorkflowKind
- AgentaNodeDTO: trace_id/span_id added (backend SpanDTO sends them)
- Org.default_workspace: list endpoint strips it - both lookups are latent
  dead code, typed as-is with comments
- FiltersPreview: operatorLabel is a display string, not the operator union

Subject: [PATCH 014/139] feat(agent-chat): voice input in the composer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a mic button to the agent-chat composer that dictates speech to text via the browser Web Speech API. Words stream into the Lexical editor live as you speak (interim + finalized), and the result is fully editable before sending.

Transcribes to plain text, so it is independent of any model/audio capability — the model receives words, not audio. The mic is hidden where SpeechRecognition is unavailable (e.g. Firefox), and shows a clear state while recording plus a mic-permission-denied message.

New: hooks/useVoiceInput.ts (typed SpeechRecognition wrapper), components/VoiceInputButton.tsx (composer-prefix mic).

Subject: [PATCH 015/139] =?UTF-8?q?feat(agent-chat):=20voice=20message=20m?=
 =?UTF-8?q?ode=20(record=20audio=20=E2=86=92=20attachment)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a second voice mode alongside voice-to-text. 'Voice message' records mic audio via MediaRecorder and drops the clip into the composer attachment tray (addFiles), same path as a picked/dropped file; 'Voice to text' transcribes as before. A mode toggle (persisted) switches between them, and only browser-supported modes are offered.

The recorded audio rides the normal attachment flow, so nothing here depends on the wire-contract or model work — it produces an audio File up to the send boundary. audio/* is now an accepted attachment type.

New: hooks/useAudioRecorder.ts (MediaRecorder → File, elapsed timer, permission/error, cleanup).

Subject: [PATCH 016/139] feat(agent-chat): full voice-message recording UX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fleshes out the voice-message flow into a proper state machine instead of the tap/tap minimum:

- Recording takeover (RecordingBar) covers the composer while capturing: live timer, input-level meter (Web Audio), and distinct Discard (cancel) vs Stop & attach (keep) exits. Esc discards.
- Permission-pending ('Waiting for microphone…') and a persistent, dismissible denied/error strip above the composer — no more hover-only tooltip.
- Hard 5-min cap with a countdown near the limit; sub-0.7s / empty takes are discarded, not attached.
- Recorded clips play back in the tray (AudioChip: play/pause + elapsed) before sending.

The recorder is owned by AgentConversation so the takeover can cover the whole input; the mic just starts it. audio/* accepted; the clip still rides the normal attachment path.

Subject: [PATCH 017/139] feat(agent-chat): default the mic to voice message,
 not dictation

Recording a voice message is the primary action; voice-to-text is the alternative. Also orders the mode menu primary-first. Falls back to dictation only where MediaRecorder is unavailable.

Subject: [PATCH 018/139] fix(agent-chat): refine the mic-permission state of
 the recording bar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The waiting state read as an error and was mis-laid-out:

- Actions now right-align (ml-auto). Previously the discard button sat jammed against the label, because the waiting state has no flex-1 meter to push it over.
- Red border only once actually capturing. Red reads as 'live'; waiting on the mic is neutral, so it now uses the normal border with a softly pulsing dot instead of an inert grey one.
- Copy is actionable rather than passive: 'Allow microphone access to start recording' (vs 'Waiting for microphone...'), and the buttons say 'Cancel' / 'Delete recording' / 'Attach to message'.
- Overlay geometry: mb-3 moved from the input to the wrapper so the bar covers the composer box exactly (inset-0) — the input no longer peeks out below.
- role=status + aria-live so the state change is announced.

Subject: [PATCH 019/139] fix(agent-chat): orchestrate the voice-recording
 state transitions with motion

Every voice surface popped in/out with no transition. Now they animate on the slice's existing idioms rather than bespoke ones:

- Mic permission/error notice -> new MicPermissionNotice using RevealCollapse (the shared composer-chrome enter/leave, same as ConnectModelBanner and the HITL dock), with the message latched in a ref so the text survives the collapse instead of vanishing mid-animation.
- Recording takeover -> AnimatePresence cross-fade + slight rise/fall on SESSION_SPRING, the same physics the session rail and tag bar use.
- Within the bar, the waiting -> capturing swap is a wait-mode cross-fade (labels never overlap); the attach button springs in; the '30s left' warning fades; and the border, dot and timer colours ease via transition-colors instead of snapping.

Subject: [PATCH 020/139] fix(agent-chat): match the recording bar to the
 composer box and scale it up
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Corner artefact on transition: the bar was rounded-xl over a rounded-lg composer, so the input's corners poked out from under it mid-cross-fade. The bar now mirrors the composer's box exactly — rounded-lg, --ag-composer-border, --ag-colorBgContainer, --ag-surface-chat-shadow — so the transition reads as the input changing state rather than a second card on top.

Sizing: the content was set against 12px defaults and read as too small inside the taller editor. Label and timer to text-sm, status dot 10->12px, action icons 16->18px, level bars taller and wider, and roomier gap/padding.

Subject: [PATCH 021/139] perf(agent-chat): stop the recorder re-rendering the
 whole conversation, and drop the takeover flash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two problems behind the sluggish, flashy recording transitions.

Perf: useAudioRecorder is owned by AgentConversation (so the takeover can cover the composer), but it held the input level in React state and wrote it every animation frame — re-rendering a ~2400-line component 60x a second. Level and elapsed now live in a ref that RecordingBar samples itself, so only that small component repaints. AgentConversation re-renders on status/error only.

Flash: an instantly-resolved permission request (already granted, or already denied) faded the takeover in and straight back out before the denied banner expanded — three animations for one click. The takeover now appears immediately when recording, but only after a 350ms grace period while a request is still pending, so instant resolutions never render it.

Subject: [PATCH 022/139] refactor(agent-chat): rAF for painted state, one
 timer for the hard cap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The recorder was mixing an rAF meter loop, a 200ms polling interval, and a second rAF in the UI. Split on the property that actually matters — rAF pauses in a background tab, timers do not:

- rAF drives everything painted (input level + the derived clock). Pausing while hidden is correct: nothing is on screen, and it stops burning battery on an invisible meter.
- A single setTimeout enforces the max-duration cap, because that must still fire when the tab is backgrounded and rAF is parked. It replaces a 200ms poll: one deadline, not 1500 wakeups over a 5-minute take.
- Elapsed is derived from a start timestamp instead of accumulated by a ticker, so it cannot drift and survives a paused loop.

Also quantises the readout to what is visible — N discrete bars and a 1Hz clock — so the 60Hz loop only triggers a render when a bar lights or the second rolls over, rather than on every frame.

Subject: [PATCH 023/139] fix(agent-chat): make cancel work while the mic
 permission is pending
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cancel (and Esc) did nothing in the waiting state: it called stop() on recRef, but no MediaRecorder exists until getUserMedia resolves, so it was a no-op on null and the bar just sat there.

Cancel now branches — stop the recorder when there is one, otherwise tear down and return to idle immediately. The browser's permission prompt can only be dismissed by the person, so the pending request is neutralised instead: if it later resolves, the stream's tracks are stopped at once rather than starting a recording that was backed out of, and if it rejects, no denied banner is shown for a request the person already abandoned.

Subject: [PATCH 024/139] fix(agent-chat): stay out of the way while the
 browser asks for the mic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A page cannot dismiss a permission prompt — getUserMedia takes no AbortSignal and there is no API to close it — so our waiting takeover offered a cancel that could not cancel, and covered the composer while the browser owned the interaction.

The takeover is now capture-only. Awaiting permission is shown on the mic itself: it pulses, is disabled (a second press only queues another request), and its tooltip points at the browser's prompt. Backing out is the prompt's own job; if it later resolves the stream is still dropped rather than starting a recording nobody asked for. RecordingBar loses its requesting branch entirely.

Also splits denied from dismissed: Chrome rejects identically for both, so the permission store is consulted and we no longer tell someone to change browser settings when they merely dismissed the prompt and could just try again.

Subject: [PATCH 025/139] feat(agent-chat): rolling FFT waveform instead of the
 level bars
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The seven threshold bars were a level meter — they showed loudness, not the take. Replaced with a rolling waveform: each slice is the FFT magnitude of one moment (voice band only, the top of the spectrum is mostly hiss), appended on the right so the recording scrolls leftward as it is spoken, older slices receding. It shows the shape of what was actually said.

Drawn on a canvas from the animation frame, which also removes it from React entirely: the previous meter had to quantise its level into discrete lit-bar counts purely to avoid repainting its parent at frame rate. Now the only React state left in the bar is the clock, at 1Hz.

Splits the concerns too — the hook owns the audio graph and exposes the analyser; the view owns sampling and drawing.

Subject: [PATCH 026/139] fix(agent-chat): stop a voice message being destroyed
 on attach
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A recording attaches like any other file, so the attachment guardrails could reject it after the fact — you record, hit attach, and the take is gone.

- At the file limit the mic is now disabled for voice-message mode (as the paperclip already was), rather than letting someone record a take that can only be rejected. Dictation is unaffected: it writes into the editor, not the tray.
- Pins the recorder to 64kbps. The default bitrate is unspecified, and a full-length take at a high one lands near the per-file size cap — the same silent-destruction path, just at the end of a five-minute recording. 64kbps is ample for voice (~2.4MB at the cap).

Subject: [PATCH 027/139] feat(agent-chat): play voice messages in the
 transcript, not just the tray
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A sent voice message rendered as an inert file card — you could record and send one but never hear it back. Audio parts now render an inline player in the transcript.

Extracts the tray's bespoke player into a shared AudioPlayer used by both surfaces, so a voice message behaves the same before and after sending, and adds a progress bar.

Also resolves the duration properly: a MediaRecorder webm reports an infinite duration until it has been seeked to the end, so the player nudges it there once and reads the real value back (guarded, so the seek never surfaces as a wild current-time reading). Previously every recording showed no duration at all.

Subject: [PATCH 028/139] fix(agent-chat): surface dictation failures, and hold
 the tray while a take is in flight
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two remaining voice gaps.

Dictation errors (a denied mic, a recognition failure) only ever appeared in the mic's tooltip — the same hover-only trap the recording path already moved away from. They now feed the shared MicPermissionNotice, so both voice modes report failures the same visible way. Only the error is lifted; the transcript stays inside the button because it changes far too often to re-render the conversation with.

A file dropped or pasted mid-recording could also take the last tray slot, so the take was rejected — and destroyed — on attach. Drops and pastes are ignored while capturing (the composer is covered by the recording bar anyway). Guarded at the entry points rather than in addFiles, because the recorder's own completion calls that directly and must always get through.

Subject: [PATCH 029/139] fix(agent-chat): brand the recording bar, reserve red
 for the record light
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bar was red four times over — border, dot, waveform, and the near-limit timer — so it read as an error state, and the one thing that should escalate had nothing left to escalate with.

- Border moves to brand. An error border is the form-validation signal; nothing about recording is invalid.
- Waveform moves to a brand tint: a single horizontal gradient across the strip, faint at the old end and near-full at the newest, so age reads as depth rather than needing a second colour. Replaces the per-bar globalAlpha ramp — one gradient built per resize, so it is also less work per frame.
- Red now means exactly one thing: the record light (and the genuine near-limit warning).

Subject: [PATCH 030/139] fix(agent-chat): give each voice mode its own icon so
 the active one is visible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both modes drew the same microphone, so picking one from the menu changed nothing on screen — the only feedback was the menu closing, leaving you unsure whether the choice registered or what to do next.

Each mode now carries its own icon (microphone for a voice message, text for dictation) and the button renders the active one, so switching visibly changes the control. The menu items carry the same icons, which is where the mapping gets taught.

Tooltips are verbs too — 'Record a voice message' / 'Dictate into the message' — so the control says what pressing it will do rather than just naming the selected mode.

Subject: [PATCH 031/139] feat(agent-chat): send a standalone voice message
 directly instead of attaching it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Confirming a recording always parked it in the tray, so a voice message recorded into an empty composer needed a second, unexplained press to actually go.

Confirm is now contextual. Recorded with nothing else composed, the take IS the message: the button becomes Send and the recording goes straight out. With text or other attachments staged, the person is mid-composition, so it still attaches and they send when ready — the icon and tooltip say which will happen before it does.

Decided when recording starts rather than on confirm: the composer is covered by the recording bar and drops are blocked while capturing, so neither the text nor the tray can change in between.

Subject: [PATCH 032/139] feat(rich-chat-input): dictate through editor nodes
 instead of rewriting the document
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dictation drove the composer with setMarkdown(base + transcript) on every interim result — a full document replace several times a second. That discarded the undo history, re-parsed markdown each tick, gave no way to distinguish settled words from provisional ones, and overwrote anything typed alongside it.

Adds a dictation session to RichChatInput (plugins/dictation). It appends two text nodes once and only sets their text as speech arrives, leaving the rest of the document untouched:

- committed words land as ordinary text, indistinguishable from typing;
- the provisional tail is styled as unsettled (opacity + italic — theme-agnostic, no colour token) and loses that styling on settle, so nothing is dropped if the recogniser never finalises it;
- updates are tagged history-merge, so a whole dictation is one undo entry rather than hundreds;
- nodes are re-resolved per update, so editor garbage collection cannot orphan the session.

A "dictating" prop locks the editor for the duration, so typing cannot interleave with the incoming transcript. useVoiceInput now reports committed and provisional text separately rather than flattening both into one string.

Subject: [PATCH 033/139] fix(agent-chat): reuse the composer's send button,
 and make both voice icons say "voice"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two things the recording bar got wrong.

It grew its own send button — a paper-plane in a plain primary circle — while the composer's real one is an arrow-up in an accent circle with its own disabled treatment. Two similar-but-different send controls in the most-used flow in the product. The presentational half is now a shared ComposerSendButton in @agenta/ui, used by the editor's SendButton plugin and by the recording bar, so sending looks and behaves the same wherever it is triggered. Only the glyph changes when the take is attached to a message in progress rather than sent outright.

The dictation mode also drew a text glyph, which says nothing about speech. Both modes now read as voice and differ by what comes out: a waveform for an audio clip, and the microphone every phone keyboard uses for dictation.

Subject: [PATCH 034/139] fix(rich-chat-input): soften the live-dictation
 styling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Interim speech was dimmed to 0.55 and italicised. Across a run that can be a whole sentence before the recogniser settles, the italic reads as emphasis and costs legibility — it was styling the majority of the message.

A gentle dim (0.65, no italic) is enough: the words are visibly rewriting themselves as they settle, which carries most of the signal on its own.

Subject: [PATCH 035/139] fix(rich-chat-input): hide the shortcut hints while
 dictating
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bold / Italic / Send / Newline stayed on screen during dictation, advertising shortcuts that cannot fire — editing is locked while speech comes in.

They fade out the same way they already fade on blur, rather than unmounting: the hints are deliberately kept mounted so their space never reflows the toolbar, and dropping them would make the row jump at the start and end of every dictation.

Subject: [PATCH 036/139] fix(agent-chat): even out the attachment tray and
 orchestrate its motion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The row mixed a two-line audio chip, 48px thumbnails and a dashed add-tile at three different heights, so it read as a ragged line rather than one band. Every tile is now the same height behind a shared chip shell, with one border treatment and one remove affordance across thumbnails, clips and file chips (on a thumbnail it sits over the image and appears on hover, so it stops covering the preview).

Tiles also had no motion at all — they appeared and vanished instantly while the rest jumped to fill the gap. Each is now a layout-animated item inside AnimatePresence on the slice's shared spring: tiles scale in on add, scale out on remove, and the survivors slide into place. popLayout is deliberate — a removed tile leaves the flow immediately so the row closes the gap while it animates out, instead of waiting for it to finish. The add-tile and counter animate with them, and the rejection strip collapses instead of popping.

 horizontally instead of wrapping

Five audio clips wrap onto five rows, growing the panel downward and pushing the composer up the screen. The tiles are now one horizontally scrolling band, mirroring the session tag bar in this slice: contained overscroll so it cannot chain to the page, motion-safe smooth scrolling, and no visible scrollbar under a 48px strip.

Details that make it behave:

- tiles are shrink-0, so a nowrap flex row cannot squash them to fit;
- the scroller is min-w-0 flex-1, without which flex refuses to shrink below content width and the panel overflows instead of scrolling;
- the counter sits outside the scroller, so it stays put rather than scrolling out of view;
- adding a file scrolls the band to the end, so a tile added past the fold is actually visible.

Subject: [PATCH 038/139] fix(ui,entities): drill-in slot types, table
 selection/locale props, windowing export

- DrillInUIContext: EditorProvider/SharedEditor slots typed with the real
  component prop types instead of a hand-written subset (root cause of the
  OSS provider assignment errors)
- InfiniteVirtualTable: rowSelection.fixed accepts antd FixedType; locale
  accepted (not yet forwarded - flagged); Editor barrel exports CodeLanguage
- workflow barrel exports WorkflowRevisionWindowing

Subject: [PATCH 039/139] fix(frontend): type-check remaining long tail; oss+ee
 tsc 0 errors

Wave-2 parallel pass over the final ~105 OSS + 11 EE-only errors, behavior-
preserving throughout (latent bugs typed as-is with NOTE comments per the
WP-4e-2a convention):

- Evaluators/Evaluations: generic evaluator filtering, chart datum typing
- pages/evaluations: NewEvaluation modal props retyped to entities-package
  shapes (stale legacy Types imports dropped); antd 6 tabPlacement vocabulary
- Testcases/Testsets/Deployments: canonical ExtendedColumnType adoption,
  dataset-store variance via Pick<...,'hooks'>
- DrillInView/EditorViews: TMode narrowing via consts, Format|CodeLanguage
  state union, html format menu typing
- app-shell misc: services/state/pages sweep with backend-verified API types
- EE Billing + misc EE-only files

Latent bugs surfaced and typed as-is (chips filed where actionable):
workspace rename sends invalid org PATCH body; SessionInspector reads
status.code the backend never sends; axios.isCancel dead on created
instance; invite accept can interpolate undefined ids

Subject: [PATCH 042/139] fix(agent-chat): reset the audio duration-probe when
 src changes

A ref-tracked WebM duration probe left probingRef stuck true if the source
changed mid-probe (ComposerAttachments recreates object URLs as attachments
change), which gated off onTimeUpdate and froze the elapsed/progress readout.
Reset it at the top of the [src] effect so each source starts a clean probe.

 recorder error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MediaRecorder fires `stop` after `error` (spec). teardown() in onerror zeroes
startedAtRef, so the trailing onstop computed tooShort=false, flipped the status
error→idle, and could emit a File from the partial chunks. Guard onstop with an
erroredRef so an errored take stays errored and never emits.

During onboarding the composer commits the ephemeral via handleCreateAgent, but a

audioSupported on !onboardingActive so the mic offers dictation only (which just

Subject: [PATCH 045/139] fix(agent-chat): make dropping files behave at the
 edges
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Whole-panel drag-and-drop already worked; its edges did not.

- Rejections could land in a closed panel. Pasting something unsupported set a rejection message nobody could see, so the attempt read as nothing having happened. Opening the panel is now part of addFiles and triggers on rejections as well as accepts, so every entry path reports back.
- Files were accepted while the composer was disabled — no provider key, or the onboarding IDE hand-off — which stages attachments into an input that cannot be sent. Drops are now refused in those states, and dragover no longer claims the drop, so the cursor stays honest.
- A dropped folder arrives in dataTransfer.files as a typeless zero-byte entry, so it was rejected as "isn't a supported file type". Folders are now detected during the drop (webkitGetAsEntry is only valid synchronously there) and named as folders.
- The drag overlay advertised the limit while already at it, inviting a drop it would reject wholesale. At the limit it says so instead.

Subject: [PATCH 046/139] feat(agent-chat): enable the attach button and give
 each kind its own size limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Attaching was reachable by paste, drop and voice message, while the one control actually labelled "attach files" stayed disabled and said "coming soon". It is now live, gated with the drop paths on the composer being usable — accepting files into an input that cannot be sent is the case worth blocking, not the button itself.

Limits become per-kind rather than one number for everything: a phone photo clears 5 MB routinely, an uploaded audio clip is larger still, and a text file is never either. Images and documents get 10 MB, audio 15 MB, with the count shared across kinds.

The shape also becomes the capability seam it was always meant to be — the accepted set is now a list of kinds, the picker's accept attribute and the "what can I attach" copy are derived from it, and narrowing that list is all capability gating will need to do. Size copy moves out of the panel and into the rejection, which can name the specific ceiling that was crossed instead of a single number that no longer exists.

Subject: [PATCH 047/139] feat(agent-chat): let model audio capability steer
 voice, without ever refusing it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Voice-to-text produces text and works against any model; a voice message needs one that can actually take audio in. Nothing reflected that, so the mic pushed "voice message" everywhere, including configs that cannot use it.

Capability now steers, per design decision D6 — it drives defaults and messaging, never a refusal:

- modalitiesForModel reads the selected model's declared input modalities from the harness catalog already on the client (sibling to contextWindowForModel). null means the catalog is silent, treated as unknown, never as "no" — so a missing field can't demote voice.
- With no explicit user choice, the mic leads with voice-to-text only when the model is known not to hear audio; otherwise voice message stays the lead. An explicit pick always wins and is remembered (new atom key, so the old always-audio default doesn't stick).
- Choosing voice message on an audio-blind model still records and attaches — the agent can use the clip with its tools — it just carries a note in the mode menu and an ear-slash + tooltip on the tray tile saying the model won't hear it.

No model in the catalog declares audio today, so in practice this leads with dictation now and self-corrects the moment an audio-capable model is wired — no code change needed.

Subject: [PATCH 048/139] fix(agent-chat): align the audio player name and time
 on one row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The name sat on the top row and the time was vertically centred against the two-row (name + progress) column, so it floated between them and read as misaligned. Name and time now share the top row with a common baseline, and the progress bar spans the full width beneath both — the standard voice-message layout.

Subject: [PATCH 049/139] refactor(drives): add a byte-source seam to the file
 viewer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The viewer's file bodies fetched bytes straight from the mount (content query, media/object-url hooks, download), which is the only thing tying the drawer to a mount. Route each through a DriveFileSourceContext that a host can provide to preview local, non-mount files (composer attachments) in the same drawer instead of a parallel viewer.

Pure refactor here: with no provider — every host today — the merge hooks return the mount result unchanged, so chat browse and the config panel behave exactly as before. Consumed by nothing yet; the attachments host and the explicit-file tree path follow.

Subject: [PATCH 050/139] feat(drives): explicit-files mode for the file drawer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DriveExplorer sourced its tree only from the mount's lazy per-directory loader. An optional explicitFiles prop now lets it render a flat list directly instead, for previewing local files (composer attachments) in the same drawer.

Three surgical changes: the tree sources from explicitFiles when present, and per-directory loading is short-circuited (a synthetic null-mount drive would otherwise report every folder as forever-loading). The rest is inert for free — repo probing, root-loading, and download-all are all already guarded on a real mount id, so a null-mount synthetic drive disables them without extra gating. FilesDrawer forwards the prop; when unset, everything is exactly as before.

Subject: [PATCH 051/139] feat(agent-chat): preview attachments in the Files
 drawer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Clicking an image thumbnail or a document chip in the composer now opens it in the same Files drawer used for agent files — the shared tree + viewer — rather than a separate previewer or nothing at all. Multiple attachments show as the tree; the clicked one is selected. Audio keeps its inline tray player, so it is not made clickable.

AttachmentViewerDrawer is the host: it turns the composer's in-memory uploads into an explicit file list plus a DriveFileSourceContext that resolves bytes from object URLs, and hands both to FilesDrawer with a synthetic mount-less drive. So it reuses DriveExplorer, the two-pane layout, tree virtualization, selection, breadcrumb, and every per-kind viewer body — no viewer is duplicated. Object URLs are built only while the drawer is open and revoked on close.

Kind resolution keys on the filename extension, so the host derives one from the media type when a name lacks it (a recorded clip, a pasted blob) — which is why resolveDriveFileKind itself needed no change.

Completes the attachment lifecycle so the upload transport is the only thing left to add.

Upload state is carried on antd's UploadFile fields (status / percent / error) and rendered by the tray, so the flow is one seam away from live:

- useAttachmentUploads owns the machine: enqueue on add, per-file progress, success, failure, retry, and abort-on-unmount. Its uploader is an injected function; until the transport exists it is left undefined, so enqueue is a no-op and files stay "done" (send behaviour unchanged). Provide the uploader and the whole flow runs — nothing else changes.
- Each tile shows its state: a progress scrim with percent while uploading, and a retry-able error overlay (message on hover) on failure.
- Aggregate: while any attachment is uploading or failed the message isn't ready, so send is gated and handleSubmit guards on it. All-"done" today, so inert until wired.

Preview errors, which were the missing half of the add-time guardrails:
- a tray thumbnail whose blob won't decode falls back to a broken-image tile instead of an empty box;
- the drawer viewer treats a local blob that fails to decode like a mount error, showing its "couldn't load" card.

Subject: [PATCH 053/139] feat(drives): mount upload transport + in-flight
 state hook
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the write side of the drawer: uploadMountFile posts a file into a mount folder with real progress via axios onUploadProgress (Fern uses fetch, which can't stream upload progress), and useMountUpload manages the in-flight items — per-file progress, retry, dismiss, abort-on-unmount — refreshing the mount's file queries on success.

Distinct from delivering a composer attachment to the model (held on the reference contract): this writes into the agent's working files via an endpoint that already exists end to end. The DriveExplorer affordance that drives it follows.

Subject: [PATCH 054/139] feat(drives): upload files into a mount from the
 Files drawer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an Upload affordance to the drawer header: it writes the picked files into the currently-viewed folder (resolved to its mount — cwd or the folded agent-files mount), with per-item progress, retry, and dismiss from useMountUpload, and refreshes the listing on success so the new files appear.

Shown only for a writable mount-backed drive — hidden in the local-file attachment preview (explicitFiles mode), which has no mount to write to. Both real hosts (chat and config) point at the agent's drive, so both get it.

This is the unblocked upload path: it writes into the agent's working files via an endpoint that already exists, and does not depend on the held composer-attachment-to-model reference contract.

Two reusable pieces the tree and grid will share.

useMountUpload now tags each in-flight item with its destination folder (plus media type and, for images, an object-URL preview) and exposes itemsFor(folder), so a view can render the pending uploads inline in the folder they're landing in rather than only in a header strip.

useDriveDrop encapsulates the drag behaviour: window-level drag tracking, per-folder hover highlight, spring-load (hover ~0.7s to drill into a folder), and drop handlers that upload into the hovered folder or — for a container/background drop — the current folder. The views just spread its handler props onto folder targets and their container.

Wires useDriveDrop into the folder grid: dragging files highlights the folder tile under the cursor, holding ~0.7s springs the view into it, and dropping uploads — onto a folder tile, or into the current folder for a background drop.

Uploads appear immediately as optimistic tiles in the open folder (synthetic nodes merged into the grid, drawn by UploadTile) with a live progress bar and, for images, a preview; on failure the tile offers retry/dismiss. On success the tile is replaced by the real file via a background refetch that keeps the grid on screen — the folder's loading gate already keys on first-load only, so there is no skeleton flash. Also drops the fetching term from the tree's per-dir loading for the same reason, and generalises the header Upload button to target any folder.

Gated to writable mounts (canUpload) — inert in the local-file attachment preview. The tree gets the same treatment next.

Mirror the grid's drop behaviour on the tree pane: folder rows are drop
targets that spring-load into the folder on hover and upload on drop, and a
background drop over the pane uploads into the current folder. Folder rows tint
while hovered. The uploaded file surfaces via the tree's silent revalidate
(no skeleton flash), so no synthetic rows are injected into the virtualized list.

Subject: [PATCH 058/139] feat(drives): ride the list motion for optimistic
 uploads in grid and tree

Make upload items enter/leave through the existing motion instead of popping:

- Grid: VirtualTileGrid now opens its reflow spring on an item-COUNT change
  (not only a column flip), so inserting or removing an optimistic upload tile
  glides the neighbouring tiles into their new slots instead of snapping. Tiles
  whose slot is unchanged (an end-append) spring to the same target, so they
  stay put. The upload tile fades+scales itself in, independent of the folder's
  one-shot reveal.
- Tree: a file appearing in an already-loaded folder (an upload landing via the
  silent revalidate) is recognised as first-ever-seen and fades in through the
  same revealFade used for first loads; a cached folder's re-expand does not
  re-fade, since those paths were seen before.

Subject: [PATCH 059/139] feat(drives): drop files onto a recents peek to stage
 them for upload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dragging files onto a Files summary (the chat ContextRail or the config
StorageSection) captures them and opens the Files drawer with the files STAGED —
nothing is written yet. A recents peek is a cross-folder, derived list with no
destination of its own, so instead of guessing a folder the drawer lets the user
choose one:

- Staged files render as ghost tiles in the grid (dashed, no progress), pinned
  across folder navigation and removable individually.
- The user browses the tree to a destination; a single "Upload N here" button in
  the drawer header commits the staged files into the folder currently in view,
  at which point they flow through the existing upload path (progress tiles + the
  list motion).
- Removing every ghost tile or closing the drawer discards staging.

Threaded generically through FilesDrawer -> DriveExplorer, so both hosts share
one implementation: the chat host stages via a per-session atom, the config host
via the existing per-revision drawer-request atom.

Subject: [PATCH 060/139] fix(drives): correct optimistic tile sizing + show
 pending items in the tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three fixes from review of the optimistic upload/staged tiles:

- Sizing/overflow: the tiles previewed the full-size dropped image as a non-absolute
  flex child, whose intrinsic min-content height overrode the thumb's 4:3
  aspect-ratio and blew the tile past its grid slot (the real FileThumb dodges this
  only because its thumbnails are tiny). Take the preview image out of flow
  (absolute inset-0) so the box stays 4:3, like FileThumb's text-preview note.
- Style: lighter, image-preserving states — a scrim + inline percent for progress,
  a scrim + Retry/Dismiss for errors, and a clearer "pending" look for staged tiles
  (primary dashed frame, upload glyph, hover-reveal remove).
- Visible in both surfaces: pending items (staged + in-flight) are a drawer-global
  set now — pinned as a compact group at the top of the TREE and shown in the grid
  regardless of which folder is open, so a dropped file shows in both views no
  matter where it was dropped.

Subject: [PATCH 061/139] fix(drives): drop the upload banner, restyle pending
 tiles to match file tiles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Layout shift: remove the full-width header upload list. It mounted/unmounted on
  every upload state change, shoving the toolbar and panes. Pending items already
  render as grid tiles + a pinned tree group, so the banner was also redundant.
- Tile styling: the staged/upload tiles now use the exact same frame as a real
  file tile (neutral border + fill, 4:3 thumb, name, one caption line); status is
  a small ABSOLUTE overlay only, so it never changes tile height or shifts the row.
  Staged = a "Staged" badge + hover remove; uploading = a thin bottom progress bar
  + "Uploading… N%"; failed = a corner warning badge + inline Failed/Retry/Dismiss.
  Drops the heavy primary tint, centered glyph, and dark scrim.

Subject: [PATCH 062/139] fix(drives): dedupe upload state so a file is never
 staged and uploading at once

Keep the two flows (recents-drop = stage, in-drawer folder drop = upload now) but
make the state robust so they can't duplicate an item:

- fileKey(name+size+lastModified) gives a picked file a stable identity.
- upload() skips any file already in flight, so a re-drop can't spawn a second
  upload item for the same file.
- uploadIntoFolder() drops any STAGED copy of a file the moment it starts
  uploading, so the same file never renders as both a staged tile and an uploading
  tile. Committing staged (Upload here) already clears the inbox; a direct folder
  drop now prunes it too.

Subject: [PATCH 063/139] fix(drives): reconcile staged inbox against in-flight
 so a file shows once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The one-shot prune only fired at upload-start, so the real repro slipped through:
a file that failed (still in-flight) and was then dropped/staged again rendered
as BOTH a Staged tile and a Failed tile.

Make the invariant continuous: every in-flight item now carries its fileKey, and
DriveExplorer reconciles the staged inbox against the in-flight key set on every
change — any staged file that is already uploading or failed is dropped from the
inbox immediately. A file is therefore staged XOR in-flight, never both, whatever
the order of drops. Retry/Dismiss on the failed tile remain the way to act on it.

Subject: [PATCH 064/139] style(drives): make dropped-file tiles read like
 plain file tiles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Strip the heavy decoration so a staged/upload tile is a normal file tile with a
quiet status line:

- Drop the black "Staged" pill and the error corner badge.
- One hover-reveal corner action on both (remove for staged, dismiss for failed),
  matching the file-tile idiom instead of always-on chrome.
- Progress is a hair-thin bar at the very bottom edge of the thumb; caption reads
  "Uploading N%".
- Failed: dimmed thumb + a compact "Failed · Retry" caption (dismiss moved to the
  corner action).
- Staged: clean thumb + a subtle "Ready to upload" caption with a small glyph.

Frame, thumb (4:3), name, and single caption line are byte-identical to
DriveFileRow's tile, so heights stay uniform with the folder/file tiles.

Subject: [PATCH 065/139] fix(drives): keep dropped-tile caption plain text so
 tiles match the grid snap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause of the oversized tiles: the failed tile's caption contained a raw
<button> (Retry). Preflight is off in this app, so a button does NOT inherit
font-size and rendered at the UA default (~13px) — taller than the 11px caption
of every other tile — which pushed the tile past VirtualTileGrid's snapped row
height and made it overflow.

Fix: every dropped-tile caption is now a PLAIN text span, byte-identical to the
folder/file caption (name text-xs + caption text-[11px]). All actions moved to
absolute overlays on the thumb (Retry = centered pill on the dimmed thumb,
Dismiss/remove = hover corner X), which can't affect tile height. Heights are now
uniform with the surrounding tiles.

Subject: [PATCH 066/139] fix(drives): force dropped-tile thumb to 4:3 with a
 padding-bottom box
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The image tiles were still taller than the folder/file tiles: a full-size
object-URL image defeats the `aspect-[4/3]` box even with the img positioned
absolutely, so the thumb rendered taller than 3/4 of its width and the tile
overflowed VirtualTileGrid's snapped row height.

Replace the aspect-ratio box with a padding-bottom aspect box: the thumb's
height is padding-bottom:75% of its width — a value the image cannot influence
because all content (image, progress, retry/dismiss overlays) lives in an
absolute inner layer. Thumb is now exactly 4:3, so the tiles measure the same as
the surrounding folder/file tiles.

Subject: [PATCH 067/139] feat(drives): render in-flight uploads as real
 tree/grid rows under their folder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Uploads no longer render as a pinned block outside the hierarchy. Each in-flight
upload now carries its drive-root-relative destination folder (+ size), and a
synthetic file entry is fed to buildDriveTree so the upload nests UNDER its folder
like any file. Both surfaces read that one tree:

- Tree: the real TreeRow renders it (correct icon/name/indent), with a trailing
  status only — spinner+% while uploading, Failed·Retry·Dismiss on error, plain
  file row once done.
- Grid: FolderView already reads the same nodes; the matching node is drawn as the
  progress/error tile (decorated by path via pendingUploadByPath).

Removes the bespoke PendingTreeRow + the grid's separate __upload__ synthetic
injection. Staged files (no destination yet) remain grid-only ghost tiles.

From 2dd90bd463828bb705ba4f6e06a3c49c08bf1c67 Mon Sep 17 00:00:00 2001

Subject: [PATCH 068/139] refactor(drives): one context-aware upload button in
 the header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the large "Upload N here" primary button — it duplicated the icon upload
button beside it. The single icon button now switches behavior by context:

- Files staged: primary-tinted (colorPrimaryBg fill + colorPrimary icon), tooltip
  "Upload N files here", commits the staged files into the current folder.
- Otherwise: neutral, tooltip "Upload to this folder", opens the file picker.

The colour change signals the difference; the tooltip carries the count.

Subject: [PATCH 069/139] style(drives): tint pending items so they read as
 distinct at a glance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Upload/staged items shared the neutral file-tile fill, so they blended in. Give
them a subtle primary tint (colorPrimaryBg fill + colorPrimaryBorder) in both
surfaces — the grid tile frame and the tree row — so a pending item is
distinguishable from a committed file without reading the caption.

Subject: [PATCH 070/139] fix(drives): always show Dismiss on a failed upload
 tile

Both surfaces already offer Retry + Dismiss on failure, but the grid tile's
Dismiss was hover-gated (opacity-0 until group-hover), easy to miss on a failed
item. Make it always visible in the error state so removing a failed upload is
obvious; the tree row already shows Retry/Dismiss inline.

Subject: [PATCH 071/139] refactor(drives): unify duplicated drop-to-stage +
 pending-tile code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two near-identical blocks the new upload work had grown collapsed into shared,
prop-controlled units:

- useStageDrop(onFiles): the recents-peek drop handler (highlight + isFileDrag +
  onDragOver/Leave/Drop) was copy-pasted in ContextRail and StorageSection with
  only the drop action differing. It now lives beside useDriveDrop and takes the
  action as a callback (falsy = disabled). Exports FileDropProps for the shared
  handler-props shape.
- PendingTile: UploadTile and StagedTile were the same tile frame/thumb/name/
  caption with different status bits. They're now thin adapters over one
  PendingTile driven by a `state` prop (staged | uploading | error | done),
  caption, and onRetry/onRemove — the frame, aspect box, and corner action live
  in one place.

No behaviour change; tsc + eslint clean.

Subject: [PATCH 072/139] refactor(drives): share object-URL previews via
 useImagePreviews + cleanup

The staged tiles (DriveExplorer) and in-flight uploads (useMountUpload) hand-rolled
the same "createObjectURL for images, revoke on settle" dance. Extract it:

- useImagePreviews(files): lazily mints an object URL per image file, revokes when
  a file leaves the list or on unmount, and returns a Map whose reference stays
  stable unless the previewed set changes (safe in memo deps). Also fixes an
  unmount leak the upload path had (previews weren't revoked on drawer close).
- useMountUpload: derives previewUrl from the hook (items now carry `file`); drops
  the manual createObjectURL + the two revoke sites.
- DriveExplorer: stagedPreviews is now one useImagePreviews(staged) call instead of
  a useMemo + cleanup effect.

Cleanup: removed the dead `itemsFor` and `mediaType` members of MountUploadItem/
MountUpload (nothing read them after uploads went global then tree-injected).

Subject: [PATCH 073/139] chore(drives): remove the SIMULATE_UPLOAD test stub

Restore the real upload transport: drop the simulated-progress branch in
uploadMountFile and the SIMULATE_UPLOAD success-persistence in useMountUpload, so
a completed upload drops the optimistic tile and the real file arrives via the
listing refetch (the file store endpoint is the source of truth again).

Subject: [PATCH 074/139] fix(agent-chat): never let a blocked file drop
 navigate the tab away
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

onDrop returned on attachmentsBlocked() before preventDefault(), so a file dropped
while blocked (recording active, or composer disabled) triggered the browser's
default action — navigating to the file and discarding the whole conversation.
And onDragOver only preventDefault'd when not blocked, so per the DnD spec the
panel wasn't even a drop target then. Make the panel ALWAYS intercept file drags
(preventDefault on enter/over/drop) and signal refusal via dropEffect="none" +
the overlay, instead of by declining to be a drop target.

 effect, not during render

useImagePreviews minted and revoked object URLs in the render body. Under React 19
concurrent rendering a discarded render would leak created URLs or invalidate

effect over a ref-held live map (revoked on unmount), publishing a state snapshot

HtmlBody's assembly bailed at !mount?.id, so a local composer HTML attachment left
the Preview tab loading forever. Make inlineHtmlAssets skip mount-asset inlining
when there's no mount while still running the sanitize + nav-interceptor pipeline,
and let the effect proceed for local content.

Subject: [PATCH 077/139] refactor(frontend): single source of truth for span
 types

The OSS tracing module declared its own TraceSpan/TraceSpanNode plus four
TypeScript enums that mirrored the zod schemas in @agenta/entities. The two
were structurally equivalent but nominally incompatible, so every crossing
needed a cast (7 of them, added in #5464 as documented scar tissue).

- oss/src/services/tracing/types now owns only TraceSpanNode (entities node
  plus the annotations the drawer stores attach) and GenerationDashboardData;
  consumers import span types from @agenta/entities/trace directly, per the
  app-layer no-re-export rule
- 25 enum value usages become string literals; StatusCode values were already
  identical, SpanCategory differed only in the catch-all
- all 7 boundary casts removed

Fixes a live crash: AGE-3788 canonicalised the backend catch-all from
"undefined" to "unknown", but spanTypeStyles was still keyed "undefined" and
both consumers destructure the lookup, so any span typed "unknown" threw a
TypeError in the observability table and trace tree. The record is now keyed
by SpanCategory (exhaustive, so a new backend category fails the build) with a
fallback at both call sites.

Nullability now matches the payload: entities declares | null where the
backend sends null, so NodeNameCell/StatusRenderer/TimestampCell props and
ScannedExportRow were widened rather than cast.

Subject: [PATCH 078/139] refactor(frontend): drop duplicate EvaluationRun,
 align step-reference shape

usePreviewEvaluations declared its own EvaluationRun while
@agenta/entities/evaluationRun already had the canonical zod-derived one.
The local copy over-declared requiredness (name/description/status/meta/flags
as non-null) where the schema says the backend can send null, so #5464 had to
hand-add updated_at to keep it current. Deleted it; the two importers and the
hook now take the type from the package.

Swapping surfaced drift inside @agenta/entities itself: the step-reference
shape was redeclared three times with different types. The core zod schema has
{id, slug?: string|null, version?: number|null}, while the ETL RunStep said
slug?: string and version?: STRING, and ColumnGroup.refs said id?: string.
Both now reference the exported EvaluationRunStepReference from the validated
schema. CandidateRun.status widened to match.

Scoped out, with reasons:
- PreviewTestset is NOT the entities Testset (different endpoint shape: it
  carries slug plus embedded data.testcases; entities Testset is lean
  metadata). PreviewTestCase does match Fern TestcaseOutput, but entities has
  no canonical testcase entity type to route it through yet.
- OrganizationProvider has no entities domain at all, and the response settings
  is a free-form dict while Fern's SsoProviderSettingsDto models create-input.
  Creating a domain for one interface is disproportionate.

Subject: [PATCH 079/139] refactor(ui): unify extended column type, clear
 dual-copy imports

Prep for retiring the duplicate InfiniteVirtualTable in oss/src/components
(55 files, a strict subset of the 67-file @agenta/ui copy).

The two copies had grown parallel abstractions for the same concept: the
package's ExtendedColumn/ExtendedColumnProps and an ExtendedColumnType added
to the OSS copy. Their bases were already equivalent (ColumnsType[number] IS
ColumnType | ColumnGroupType), so the package type just gained the three props
it lacked (defaultHidden, maxWidth, exportEnabled) and the OSS type is now an
alias of it.

Three files imported BOTH copies at once (TestcasesTableShell,
getObservabilityColumns, getSessionColumns); each needed only the column type
from the OSS side, so they now take it from the package. No file imports both
copies anymore.

Subject: [PATCH 080/139] refactor(ui): delete duplicate InfiniteVirtualTable,
 migrate to @agenta/ui
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The library existed twice: 55 files in oss/src/components/InfiniteVirtualTable
(a strict subset) and the canonical 67-file copy in @agenta/ui. Fixes to
either had to be applied to both — this session alone hit that with the
rowSelection.fixed widening and the ExtendedColumnType consolidation.

- Migrated all 33 app consumers from @/oss/components/InfiniteVirtualTable to
  @agenta/ui/table (the barrel already re-exported every symbol they used).
- Deleted the 55-file OSS copy.
- Package exports ColumnVisibilityNodeMeta / ColumnVisibilityNodeMetaResolver
  (needed by a migrated consumer).

Preserved the export permission gate. The retired OSS shell computed
exportEnabled = enableExport && canExportData internally; the package shell has
no permission check and defaults enableExport=true. The two consumers that
relied on the implicit gate (EvalRunDetails/Table.tsx,
EvaluationRunsTablePOC/.../EvaluationRunsTable/index.tsx) now pass
enableExport={canExportData} explicitly. tsc could not have caught this — both
sides are boolean.

TestsetsTable needed two behavior-preserving adjustments where the package
types are wider: String(record.key) at two Set<string>/string[] lookups (keys
are UUIDs, so a no-op) and 'as never' on the invariant datasetStore generic
(mirrors DeploymentsTable).

Subject: [PATCH 081/139] chore(frontend): modernize tsconfig, add native TS7
 type-check

Two production-ready changes plus an opt-in fast type-checker, stacked on the
tsc-cleanup work. Both apps stay at 0 errors throughout.

1. tsconfig modernization (real change, toolchain-neutral). Switched oss/ee to
   the relative-paths, no-baseUrl form. This is the modern standard: classic
   TS 5.9 accepts it, and it is also what TS7 REQUIRES (it removed baseUrl --
   TS5102 -- and disallows non-relative path values -- TS5090).

2. CSS side-effect import typing (real change, additive). Added css-modules.d.ts
   per app, mirroring packages/css-modules.d.ts, so asset imports are typed.
   TS7 needs this (TS2882); classic tolerated untyped CSS under
   moduleResolution:bundler.

3. Opt-in native type-check. Adds @typescript/native-preview (the isolated tsgo
   binary -- does NOT replace typescript@5.9, so typescript-eslint and next build
   are untouched) and a type-check:native script. Usable today for a faster
   local loop: OSS check-to-zero 18.1s (classic) -> 3.7s (native), ~4.9x.
   Also adds a plain type-check (classic) script; there wasn't one.

Verified all four gates green with these changes:
  native tsgo: oss 0, ee 0    classic tsc: oss 0, ee 0
  next build oss: exit 0 (Next resolver handles no-baseUrl)
  lint oss (typescript-eslint): exit 0

Deferred (not in this PR): making native the ENFORCED gate (CI/pre-commit/next
build). The hard blocker is typescript-eslint: TS7.0 shipped without a stable
compiler API (7.1 will add one), and npm refuses to install typescript-eslint
alongside typescript@7 at all (ERESOLVE) -- so flipping the lint job to native
is not yet possible. Whether next build's internal type-check is also blocked
is unverified: it depends on whether Next consumes the programmatic API or
shells out to the tsc binary. This PR does not touch either gate; it makes the
later flip a small change and measures the win now.

Subject: [PATCH 083/139] fix(api): keep /api on slash redirects so they don't
 escape to the web app
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ApiPrefixStripMiddleware rewrites scope["path"] before routing, so Starlette
builds its trailing-slash redirect from the stripped path. Behind a path-prefixed
proxy the 307 for /api/<route> (no trailing slash) points at /<route>/, which is
served by the web UI — the caller gets an HTML 404 instead of the API response.

Re-prefix 307/308 Locations on the way out, only when this middleware actually
stripped, and only for root-relative paths so off-host redirects (SuperTokens
callback) are untouched.

Subject: [PATCH 084/139] fix(api): resolve the trailing slash in-place instead
 of redirecting

Correcting the redirect's Location was the wrong shape. A client holding a
cached slash-normalizing 308 gets a redirect loop: its cache rewrites slashed
to unslashed, the corrected Location sends unslashed back to slashed. Observed
on a self-hosted deployment as ERR_TOO_MANY_REDIRECTS.

Match the trailing slash against the route table on the way in and disable
redirect_slashes, so both shapes resolve directly and no Location is ever
emitted. That removes the escape and the loop together.

+# Simplify navigation for new signup users
+
+**Status:** Planning complete — decisions locked, ready to implement
+**Date:** 2026-07-24
+
+New signup users land on the full platform sidebar, which is noise when their only goal is
+building an agent. This workspace plans a nav-only simplification in two phases. **Phase 1**
+hides the advanced pages (Prompts, the Evaluation group, Overview, Registry, Evaluations) for
+new signups. **Phase 2** adds a per-user **"Simplified navigation"** toggle in Settings →
+Account so anyone can switch back to the full view to use the LLM-app pages. Existing and
+returning users default to the full view throughout.
+
+## Decisions
+
+- Two phases: Phase 1 = hide-for-new-signups; Phase 2 = the Settings → Account toggle
+  (additive — touches no Phase-1 file except one derived atom).
+- Nav-only — hide sidebar entries; no route guards, no in-app link changes.
+- Hide when simplified: Prompts, Evaluation group (project); Overview, Registry, Evaluations (app).
+- Keep always: Home, Agents, Observability, app Playground.
+- Default mode seeded by `isNewUser` (new signups → simplified); everyone else → full.
+- Stable seam: the sidebar hook reads `isNavSimplifiedAtom` — Phase 1 `= isNewUser`, Phase 2
+  `= override ?? isNewUser`.
+- No backend, no team-wide enforcement — per-user preference; an invited teammate flips the
+  Phase-2 switch to match their team. A workspace-level flag is deferred, not blocked.
+- Built on the sidebar's existing `isHidden` mechanism; one OSS sidebar file, both editions inherit it.
+
+## Deliverables
+
+- [context.md](./context.md) — problem, phased scope, out-of-scope, product language, success criteria.
+- [research.md](./research.md) — how the sidebar, new-user state, and settings tabs work today, with `file:line`.
+- [plan.md](./plan.md) — the phased, sliced implementation plan (Phase 1: Slice 0–4; Phase 2: Slice 5–6).
+- [status.md](./status.md) — locked decisions, open questions, next action.
+
+## Intended outcome
+
+A user who has just signed up sees a focused, agent-first sidebar: Home, Agents, and
+Observability at the project level, Playground + Observability inside an app. Anyone who wants
+the complete platform — an existing LLM-app team, or an invited teammate — flips one switch in
+Settings → Account and gets it back, with the choice remembered. No one is ever stuck in the
+wrong view.

+# Context — Simplify navigation for new signup users
+
+## Problem
+
+The sidebar exposes the full platform to everyone the moment they sign up. For a brand-new
+user whose only goal is building an agent, that surface is noise: Prompts, the whole
+Evaluation group, Registry, Evaluations, and the app Overview are pages the agent flow does
+not need yet. They add cognitive load and lead to dead-end or empty pages during the first
+session.
+
+The product has pivoted to agent building (see `docs/design/onboarding-revamp/HANDOFF.md`).
+The navigation should match that focus for people arriving new — while still letting anyone
+who needs the full platform switch to it.
+
+## Scope
+
+Nav-only. The entries disappear from the sidebar; nothing else changes. Delivered in two
+phases.
+
+**Advanced items hidden when the simplified view is active:**
+
+Project scope (`projectItems` in `useSidebarConfig`):
+- Prompts
+- Evaluation — the entire group (Test sets, Evaluators, Evaluation runs, Annotation Queues)
+
+App scope (`appItems` in `useSidebarConfig`):
+- Overview
+- Registry
+- Evaluations
+
+Everything else always stays: Home, Agents, project Observability; app Playground and app
+Observability.
+
+### Phase 1 (this delivery) — hide for new signups
+
+New signup users (`isNewUser === true`) get the simplified sidebar. Everyone else is
+unaffected. There is no switch yet, so a genuinely-new solo user stays simplified until
+Phase 2 ships. Invited teammates already read `isNewUser === false` (see research.md §7), so
+they keep the full nav.
+
+### Phase 2 (follow-up) — the toggle
+
+A "Simplified navigation" switch in **Settings → Account**, backed by a per-user localStorage
+override. It flips the mode either way: a new user can reveal everything (e.g. to use the
+LLM-app pages), and an existing user or invited teammate can opt into the focused view. Phase 2
+is additive — it changes no Phase-1 file except the one derived atom.
+
+## Out of scope (both phases)
+
+- **Route guards.** Direct URLs (`/prompts`, `/evaluations`, `/apps/[id]/overview`,
+  `/apps/[id]/variants`, `/apps/[id]/evaluations`) still resolve. We only remove the nav
+  entry points.
+- **In-app links.** Buttons or cards elsewhere that navigate to a hidden page keep working.
+- **Team-wide enforcement.** The preference is per-user, not per-workspace. An agent team's
+  invited teammate defaults to the full view and (in Phase 2) flips the switch to match the
+  team; we do not force every member to the same mode. A workspace-level flag would do that,
+  but it needs a backend field and is deferred. The override model does not block adding it.
+- **A backend field.** No server change in either phase. Everything is client-side localStorage.
+
+## Product language
+
+- **New signup user** — a user for whom `isNewUserAtom` is `true`. Set once on first signup,
+  persisted per-user in localStorage, never cleared today.
+- **Simplified navigation** — the reduced, agent-focused sidebar (advanced items hidden).
+- **Full navigation** — the complete sidebar (today's behavior).
+- **Simplified-nav preference** — the per-user override (`simplifiedNavOverrideAtom`):
+  `null` = follow the default, `true` = force simplified, `false` = force full.
+- **Effective mode** — `override ?? isNewUser`, exposed as `isNavSimplifiedAtom`. This single
+  value drives both the sidebar and the settings switch.
+
+## Success criteria
+
+**Phase 1**
+1. A new signup user sees the simplified sidebar (no Prompts, Evaluation group, Overview,
+   Registry, or Evaluations).
+2. An existing/returning user sees the full sidebar exactly as before.
+3. Both editions (OSS and EE) get the behavior from one sidebar change — no EE fork.
+4. Hidden items never render, auto-open, or become the selected key while simplified.
+5. No backend change is introduced.
+
+**Phase 2**
+6. The Settings → Account switch flips the effective mode in either direction and survives a
+   reload.
+7. Toggling the switch updates the sidebar without a full page reload.
+8. Phase 1's sidebar behavior is unchanged when no override is set.

+once (Phase 1) and never touched again:
+
+- **Phase 1:** `isNavSimplifiedAtom = isNewUser` (thin passthrough).
+- **Phase 2:** `isNavSimplifiedAtom = override ?? isNewUser` (add the override; same name, same
+  consumers).
+
+The hook `useHideAdvancedNav` reads `isNavSimplifiedAtom` in both phases and never changes.
+
+---
+
+# Phase 1 — Hide advanced nav for new signups
+
+## Slice 0 — Pin the current sidebar with a test
+
+1. Unit test over `useSidebarConfig` output (or `filterVisibleItems` on the built items)
+   asserting the five target keys are **present** when `isNavSimplified === false`.
+2. Assert non-targets (Home, Agents, Observability, app Playground) are present in both modes.
+
+**Exit:** a passing test capturing the pre-change sidebar (targets + non-targets visible).
+
+## Slice 1 — The derived atom + hook
+
+1. Add `web/oss/src/state/navPreference/atoms.ts`:
+
+   ```ts
+   import {isNewUserAtom} from "@/oss/lib/onboarding"
+   import {atom} from "jotai"
+
+   // Phase 1: simplified nav follows new-signup status. Phase 2 adds a user override here.
+   export const isNavSimplifiedAtom = atom((get) => get(isNewUserAtom))
+   ```
+
+2. Add `web/oss/src/components/Sidebar/hooks/useHideAdvancedNav.ts`:
+
+   ```ts
+   import {useAtomValue} from "jotai"
+   import {isNavSimplifiedAtom} from "@/oss/state/navPreference/atoms"
+
+   /** Advanced sidebar areas are hidden while the simplified view is active. */
+   export const useHideAdvancedNav = (): boolean => useAtomValue(isNavSimplifiedAtom)
+   ```
+
+**Exit:** `isNavSimplifiedAtom` returns `isNewUser`; hook compiles and is unit-referenced.
+
+## Slice 2 — Hide the two project-scope items
+
+Edit `web/oss/src/components/Sidebar/hooks/useSidebarConfig/index.tsx`.
+
+1. `const hideAdvancedNav = useHideAdvancedNav()` near the top.
+2. Prompts (`PROMPTS_SIDEBAR_KEY`, `:72`): add `isHidden: hideAdvancedNav`.
+3. Evaluation group (`evaluation-group`, `:88`): add `isHidden: hideAdvancedNav`.
+4. Add `hideAdvancedNav` to the `projectItems` `useMemo` deps.
+
+**Exit:** with `isNewUser` true, `projectItems` (post `filterVisibleItems`) has no Prompts and
+no `evaluation-group`; with it false, both present. Non-targets unchanged.
+
+## Slice 3 — Hide the three app-scope items
+
+Same file, `appItems` memo (`:144`).
+
+1. Overview (`:147`), Registry (`:164`), Evaluations (`:174`): change `isHidden: isHidden` to
+   `isHidden: isHidden || hideAdvancedNav`. Do **not** touch Playground or app Observability.
+2. Add `hideAdvancedNav` to the `appItems` `useMemo` deps.
+
+**Exit:** with `isNewUser` true, `appItems` (post `filterVisibleItems`) has no Overview,
+Registry, or Evaluations, and still has Playground + Observability when the app-context gate
+allows. With it false, all five behave exactly as before.
+
+## Slice 4 — Manual QA (Phase 1)
+
+1. Run the local stack (OSS + dev per root `AGENTS.md`).
+2. New user: set `agenta:onboarding:active-user-id` to the user id and
+   `agenta:onboarding:<id>:is-new-user` to `true`, reload → simplified sidebar. Confirm the
+   five items gone, Home/Agents/Observability/Playground remain.
+3. Set `is-new-user` to `false`, reload → full sidebar returns.
+4. Check both the main (project) and workflow (app) sidebars.
+5. Confirm no empty section header / stray divider where the Evaluation group was
+   (`filterVisibleSections` drops empty sections — verify visually).
+
+**Exit:** both states verified in the running app; `pnpm lint-fix` clean. **Phase 1 shippable.**
+
+---
+
+# Phase 2 — Settings → Account toggle (follow-up)
+
+Additive. Nothing from Phase 1 changes except the body of `isNavSimplifiedAtom`.
+
+## Slice 5 — The override state
+
+Edit `web/oss/src/state/navPreference/atoms.ts`:
+
+```ts
+import {atomWithStorage} from "jotai/utils"
+
+/** null = follow default, true = force simplified, false = force full. Per-user via LS. */
+export const simplifiedNavOverrideAtom = atomWithStorage<boolean | null>(
+    "agenta:nav:simplified-override",
+    null,
+)
+
+// Phase 2: explicit choice wins; else fall back to new-signup default.
+export const isNavSimplifiedAtom = atom((get) => {
+    const override = get(simplifiedNavOverrideAtom)
+    return override ?? get(isNewUserAtom)
+})
+```
+
+Unit test: override `null` → `isNewUser`; override `true`/`false` → that value.
+
+**Exit:** derived atom follows the table in `context.md`, proven by the test. Sidebar behavior
+from Phase 1 is unchanged when no override is set.
+
+## Slice 6 — The switch
+
+1. Add `web/oss/src/components/pages/settings/Account/NavigationPreference.tsx`: an antd `Switch`
+   labeled "Simplified navigation" with a one-line description ("Hide advanced features —
+   Prompts, Evaluations, Registry — for a focused agent workspace"). `checked` reads
+   `isNavSimplifiedAtom`; `onChange` writes the boolean to `simplifiedNavOverrideAtom`.
+2. Render it in the Account tab, above `DeleteAccount`, at
+   `pages/w/[workspace_id]/p/[project_id]/settings/index.tsx:171` (`case "account"`).
+
+**Exit:** toggling shows/hides the advanced items live (no reload); the choice survives a
+reload; both directions verified. Non-new users can now opt into simplified, and new users can
+reveal everything.
+
+---
+
+## Files touched
+
+**Phase 1**
+- `web/oss/src/state/navPreference/atoms.ts` — new, `isNavSimplifiedAtom` (passthrough).
+- `web/oss/src/components/Sidebar/hooks/useHideAdvancedNav.ts` — new, ~4 lines.
+- `web/oss/src/components/Sidebar/hooks/useSidebarConfig/index.tsx` — five `isHidden` edits +
+  hook call + two dep-array entries.
+- Sidebar visibility test (new or extended).
+
+**Phase 2**
+- `web/oss/src/state/navPreference/atoms.ts` — add `simplifiedNavOverrideAtom`, extend the
+  derived atom.
+- `web/oss/src/components/pages/settings/Account/NavigationPreference.tsx` — new switch.
+- `web/oss/src/pages/w/[workspace_id]/p/[project_id]/settings/index.tsx` — render the switch in
+  the `account` case.
+
+No changes to `engine/`, `scopes/`, `lib/onboarding/`, or any EE file, in either phase.
+
+## Rollback
+
+Phase 1: delete the two new files, the hook call, and the five `isHidden` edits — pure code
+revert, no data migration, no server state. Phase 2: delete the switch + settings render and
+revert the derived atom to the passthrough; the harmless `agenta:nav:simplified-override`
+localStorage key can be left.

+# Research — how the sidebar and new-user state work today
+
+All line references are current at the time of writing.
+
+## 1. One file owns every target item
+
+`web/oss/src/components/Sidebar/hooks/useSidebarConfig/index.tsx` builds two arrays:
+
+- `projectItems` (project scope) — `web/.../useSidebarConfig/index.tsx:52`
+- `appItems` (app scope) — `web/.../useSidebarConfig/index.tsx:144`
+
+`projectItems` feeds the main sidebar via `mainScope.tsx:48`. `appItems` feeds the workflow
+sidebar via `workflowItems.ts:29`. No EE file overrides `useSidebarConfig`, `mainScope`, or
+`workflowItems` (verified with `find ee/src`), so a single OSS change reaches both editions.
+
+### Target items and their exact lines
+
+| Item | Scope | Key | Line |
+| --- | --- | --- | --- |
+| Prompts | project | `PROMPTS_SIDEBAR_KEY` | `:72` |
+| Evaluation (whole group) | project | `evaluation-group` | `:88` |
+| Overview | app | `overview-link` | `:147` |
+| Registry | app | `app-variants-link` | `:164` |
+| Evaluations | app | `app-evaluations-link` | `:174` |
+
+The Evaluation group at `:88` is a single item with a `submenu` (Test sets, Evaluators,
+Evaluation runs, Annotation Queues). Hiding the group hides all four children.
+
+## 2. The `isHidden` mechanism already does exactly what we need
+
+`SidebarConfig.isHidden` (`engine/types.ts:12`) is honored by
+`engine/visibility.ts:filterVisibleItems`:
+
+```ts
+items.flatMap((item) =>
+    item.isHidden ? [] : [{...item, submenu: item.submenu ? filterVisibleItems(item.submenu) : undefined}])
+```
+
+It runs recursively and drops flagged items at every level, so a hidden item never renders,
+never auto-opens, and never becomes the selected key. `filterVisibleSections` then drops any
+section left empty. This is the sanctioned seam — set `isHidden` and the engine does the rest.
+
+**Seam detail:** `projectItems` targets (Prompts, evaluation-group) have no `isHidden` today,
+so we add one. `appItems` targets already carry `isHidden` bound to the app-context gate
+`const isHidden = !hasAppContext && !currentApp && !recentlyVisitedAppId` (`:145`). We must
+**OR** our condition onto that existing value, not overwrite it, or we would re-show items
+that the app-context gate intends to hide.
+
+## 3. The "new user + localStorage" infrastructure already exists — reuse it
+
+`web/oss/src/lib/onboarding/atoms.ts`:
+
+- `isNewUserAtom` (`:45`) reads/writes a per-user, localStorage-backed value under
+  `agenta:onboarding:${userId}:is-new-user` (`atomWithStorage`, `:22`).
+- It returns `false` when `onboardingStorageUserIdAtom` (`:14`, LS key
+  `agenta:onboarding:active-user-id`) is unset.
+
+Lifecycle, verified by grep:
+
+- **Set `true`** on first signup in `web/oss/src/hooks/usePostAuthRedirect.ts:136` (EE) and
+  `:147` (OSS), driven by `is_new_user` in the SuperTokens session payload.
+- **Set `false`**: nowhere. `grep` for `setIsNewUser(false)` / `isNewUser(false)` returns no
+  call. The atom's own doc comment claims it flips on tour completion, but that code path does
+  not exist. So today the flag is **sticky-true per browser** once a user signs up.
+- `onboardingStorageUserIdAtom` is set for every authed user (`usePostAuthRedirect.ts:114`),
+  but `isNewUser` is only *written* when the payload says new. A returning user on a fresh
+  browser therefore reads the family default `false` → full nav. Only genuine fresh signups
+  read `true`.
+
+Already consumed the same way by observability onboarding
+(`components/pages/observability/components/{ObservabilityTable,SessionsTable}/index.tsx`) and
+the onboarding widget, so `useAtomValue(isNewUserAtom)` inside a hook is an established pattern.
+
+## 4. One interaction, not a current blocker
+
+`components/Onboarding/tours/firstEvaluationTour.ts:188` targets
+`selector: '[data-tour="evaluations-nav"]'` — the app-scope Evaluations item we will hide.
+But the whole tour engine is parked: `lib/onboarding/constants.ts:8` sets
+`ONBOARDING_TOURS_ENABLED = false`, and the tour is registered/started only under that flag
+(`Playground/PlaygroundOnboarding.tsx:23`). So there is no live conflict today.
+`deployPromptTour.ts:33` references the Registry nav item but the selector is commented out.
+
+**Follow-up (not this delivery):** if tours are re-enabled, `firstEvaluationTour` must either
+not run for new users or not depend on the hidden nav item.
+
+## 5. SSR / hydration note
+
+`atomWithStorage` hydrates from localStorage on the client. During SSR and first paint the
+value is the default (`false`), so a new user could see the advanced items for one frame
+before they disappear on hydration. This matches the existing observability-onboarding
+behavior (same atom, same pattern), so it is acceptable for the MVP. If the flash is
+objectionable, `atomWithStorage(..., {getOnInit: true})` or gating render on a
+mounted/hydrated flag are the standard fixes — noted, not required.
+
+## 6. The settings surface for the toggle already exists
+
+Settings tabs are declared in
+`web/oss/src/components/pages/settings/assets/navigation.ts`. There is already an `account`
+tab (`SettingsTabKey`), and its content renders at
+`web/oss/src/pages/w/[workspace_id]/p/[project_id]/settings/index.tsx:171` —
+`case "account": ... content: <DeleteAccount />`. The Account content folder
+(`components/pages/settings/Account/`) currently holds only `DeleteAccount.tsx`, so it is a
+clean place to add a "Simplified navigation" switch above the delete-account block.
+
+## 7. Per-user vs per-workspace — why the toggle is the chosen shape
+
+The intent ("simplify for agent-focused people") is really a per-*workspace* property, but the
+only ready signal (`isNewUser`) and the chosen storage (localStorage) are per-*user*. A per-user
+preference therefore cannot force a whole team to match. Verified consequence in the invite flow:
+`usePostAuthRedirect.ts` calls `setIsNewUser(true)` only in the **non-invited** branches
+(`:136`, `:147`); an invited teammate returns at `:128–:131` before the flag is set, so they read
+`isNewUser === false` → full nav, even when the inviter (a fresh agent signup) sees the simplified
+nav. The toggle resolves this at the individual level: the teammate flips one switch to match.
+Team-wide enforcement would require a workspace-level flag (backend), which is deferred.
+
+## Seams to pin in the plan
+
+1. A per-user preference atom `simplifiedNavOverrideAtom` (`boolean | null`, localStorage) plus
+   a derived `isNavSimplifiedAtom = override ?? isNewUser`. One value, two consumers.
+2. `projectItems`: Prompts and evaluation-group need a new `isHidden` bound to
+   `isNavSimplifiedAtom`.
+3. `appItems`: Overview, Registry, Evaluations need `isHidden` **OR-ed** with the existing
+   app-context `isHidden`, not replaced.
+4. The condition must reach the sidebar through a single hook/selector so it lives in one place.
+5. Non-targets (Home, Agents, Observability, Playground) must remain untouched.
+6. The Settings → Account switch reads and writes the same preference, so the sidebar and the
+   switch never disagree.

+# Status — Simplify nav for new signup users
+
+**Last updated:** 2026-07-24
+
+## Current stage
+
+Planning complete, split into two phases. **Phase 1** (ship now): hide the advanced nav for
+new signups. **Phase 2** (follow-up): a per-user "Simplified navigation" toggle in
+Settings → Account. No code written. Ready to implement Phase 1 on its own branch.
+
+## Locked decisions
+
+- **Phased delivery.** Phase 1 = hide-for-new-signups. Phase 2 = the Settings → Account toggle.
+  Phase 2 is additive — it touches no Phase-1 file except the body of `isNavSimplifiedAtom`.
+- **Hide scope: nav-only.** Remove the sidebar entries only. No route guards, no in-app link
+  changes.
+- **Items hidden.** Project: Prompts, Evaluation group (all four children). App: Overview,
+  Registry, Evaluations.
+- **Items kept.** Home, Agents, project Observability; app Playground, app Observability.
+- **Default mode = seeded by `isNewUser`.** New signups default to simplified; everyone else
+  defaults to full. No new signup-time storage — reuse `isNewUserAtom`.
+- **Stable seam.** The sidebar hook `useHideAdvancedNav` reads one derived atom
+  `isNavSimplifiedAtom`. Phase 1: `= isNewUser`. Phase 2: `= override ?? isNewUser`. The hook
+  and the five sidebar edits are written once and never change.
+- **Phase 1 has no escape hatch (accepted).** A genuinely-new solo user stays simplified until
+  Phase 2. Acceptable because that user is exactly the target audience and Phase 2 follows;
+  invited teammates already see the full nav (not flagged).
+- **Phase 2 override.** A per-user localStorage `simplifiedNavOverrideAtom`
+  (`null | true | false`); switch in **Settings → Account**. Graduation becomes manual, anytime.
+- **No backend, no team-wide enforcement.** Per-user preference. An invited teammate flips the
+  switch (Phase 2) to match the team; we do not force a whole workspace to one mode. A
+  workspace-level flag (backend) would, and is deferred; the override model does not block it.
+- **Mechanism: the existing `isHidden` flag** + `filterVisibleItems` engine. No engine change.
+- **App-scope OR-ing.** Overview/Registry/Evaluations: OR the condition onto the existing
+  app-context `isHidden`, do not replace it.
+- **One OSS sidebar file** changes; both editions inherit it (no EE fork exists).
+- **Parked tour: no action.** Tours stay disabled (`ONBOARDING_TOURS_ENABLED = false`), so
+  `firstEvaluationTour`'s reference to the hidden Evaluations item is a non-issue.
+- **Empty sections: filter them out.** `filterVisibleSections` already drops zero-item
+  sections; QA confirms nothing residual renders.
+- **Override scope (Phase 2): global-per-browser.** One `agenta:nav:simplified-override` key,
+  not per-user. Accepted the shared-browser leak as negligible for MVP.
+- **SSR/hydration flash: accept and judge in QA.** Ship as-is; only reach for `getOnInit` /
+  a hydrated-gate if the one-frame flash actually looks bad.
+
+## Open implementation questions
+
+None. All resolved (2026-07-24). Ready to build.
+
+## Next action
+
+Implement Phase 1, Slice 0 (pin current sidebar with a test) on a fresh branch, then
+Slices 1–4. Phase 2 (Slices 5–6) follows as a separate delivery.

Subject: [PATCH 086/139] feat(onboarding): add navSimplifiedDefault atom and
 use itIntroduce a durable per-user nav default to control the simplified,

-focused sidebar for new signups without impacting existing users.

- export navSimplDefaultAtom from onboarding index- read and set navSimplifiedDefaultAtom in post-auth redirect hook so signup flow seeds the simplified-nav default when creating new users- add advancedNavHiddenAtom selector that derives from the new durable navSimplifiedAtom (separating signup-era default from transient isOnboarding/isUser state)
- update design docs to explain the new atom, the rationale (do not reuse sticky isNewUserAtom) and the1/Phase2 migration seamThis prevents existing users from losing advanced navigation due to thesticky isNewUser flag while allowing newups to get a simplifiedsidebar by default.

-1. Add `web/oss/src/state/navPreference/atoms.ts`:
+1. Add the durable per-user default in `web/oss/src/lib/onboarding/atoms.ts` (reuses the
+   existing per-user scoping infra — `onboardingStorageUserIdAtom`, `createScopedStorageKey`):
 
    ```ts
-   import {isNewUserAtom} from "@/oss/lib/onboarding"
-   import {atom} from "jotai"
-
-   // Phase 1: simplified nav follows new-signup status. Phase 2 adds a user override here.
-   export const isNavSimplifiedAtom = atom((get) => get(isNewUserAtom))
+   const navSimplifiedDefaultAtomFamily = atomFamily((userId: string) =>
+       atomWithStorage<boolean>(createScopedStorageKey(userId, "nav-simplified"), false),

+           if (userId) set(navSimplifiedDefaultAtomFamily(userId), next)
+       },
+   )
    ```
 
-2. Add `web/oss/src/components/Sidebar/hooks/useHideAdvancedNav.ts`:
+   Export it from the `lib/onboarding` barrel.
 
-   ```ts
-   import {useAtomValue} from "jotai"
-   import {isNavSimplifiedAtom} from "@/oss/state/navPreference/atoms"
+2. Seed it at signup in `web/oss/src/hooks/usePostAuthRedirect.ts`: call
+   `setNavSimplifiedDefault(true)` next to each `setIsNewUser(true)` (EE and OSS non-invited

-   /** Advanced sidebar areas are hidden while the simplified view is active. */
-   export const useHideAdvancedNav = (): boolean => useAtomValue(isNavSimplifiedAtom)
+3. Add the derived seam atom to `web/oss/src/state/onboarding/selectors.ts`, next to
+   `deadEndNavDisabledAtom` (imports `navSimplifiedDefaultAtom` from `@/oss/lib/onboarding/atoms`):
+
+   ```ts

    ```

Subject: [PATCH 088/139] feat: Implement InteractionDock for handling
 client-tool interactions

- Added InteractionDock component to manage parked client-tool interactions, mirroring ApprovalDock's functionality.
- Introduced WaitingForInput component to indicate when the agent is waiting for user input.
- Updated AgentConversation to integrate InteractionDock and display waiting states appropriately.
- Enhanced QueuedMessages to reflect held messages when the interaction is pending.
- Refactored ConnectToolWidget to utilize useConnectFlow for managing connection states and actions.
- Added useConnectFlow hook to centralize connection logic for both InteractionDock and inline components.
- Updated state management to include isPendingClientToolInteraction for better handling of client-tool interactions.

+/**
+ * Persistent "the agent is waiting for you" band for parked CLIENT-TOOL interactions — the sibling
+ * of ApprovalDock with the same placement contract: it lives in the composer region (between the
+ * transcript and the input) so a paused run can't scroll out of reach, and it OWNS the actions
+ * while the inline transcript row is just a marker.
+ *
+ * Why it exists (UX): when the runner parks a `request_connection`, the stream genuinely ends —
+ * `useChat` reads "ready", so nothing busy-derived (working dots, stop button) signals the pause,
+ * while the message queue silently holds every send (`isHitlPending`). This dock makes the paused
+ * state visible where the user is typing AND provides the escape hatch a parked connection
+ * previously lacked: "Not now" settles the call as a structured decline, so the run resumes and
+ * the conversation unfreezes.
+ *
+ * v1 covers the connect interaction (`request_connection` / render.kind "connect"). Elicitation
+ * stays inline — it's a form the user fills in the transcript, and it carries its own
+ * Decline/Dismiss actions; the composer's waiting state covers its visibility.

- * The agent asked for a connection it lacks (e.g. GitHub). This widget runs the Agenta OAuth flow in
- * the playground and settles the parked call with a **reference, never a secret**: the runner
- * re-resolves the credential from the project vault on resume. It reuses the existing connection
- * machinery (`useToolsConnections` → `POST /tools/connections/`, then a popup on the returned
- * `redirect_url`) rather than reinventing the OAuth call.
+ * The agent asked for a connection it lacks (e.g. GitHub). While the call is PARKED, this inline
+ * row is a passive marker only — the actions (Connect / Not now / Cancel) live in the
+ * InteractionDock in the composer region, mirroring ApprovalDock's "dock acts, inline marks"
+ * contract, so the paused run can never scroll out of reach and always has an escape hatch.
  *
- * Security (hard requirement, design §"Security"): the popup posts back a `tools:oauth:complete`
- * message; we trust it ONLY when `event.origin` equals the Agenta API origin (the callback page's
- * origin) and the payload shape matches. Everything else is dropped. The callback also tags the
- * message with the connection's `slug`/`integration`, so when several connect widgets are live at
- * once each settles only on its OWN completion (never on a sibling's).
- *
- * Settle on every terminal path (design §"Settle on every path"), so the run never hangs:
- *   success → {connected:true, integration, slug} · cancel/abandon → {connected:false,
- *   reason:"cancelled"} · timeout → {connected:false, reason:"timeout"} · failure → errorText.
- *
- * Result UX is U1 — an inline status chip in the same visual language as approve/deny: "Connect
- * GitHub" → "Connecting GitHub…" → "GitHub connected" ✓, or "Connection not completed" + Retry.
+ * After the call settles this row owns the result UX (U1) — an inline status chip in the same
+ * visual language as approve/deny: "GitHub connected" ✓, or "Connection not completed" + Retry
+ * (which re-runs the OAuth via the shared `useConnectFlow`, priming the vault for the agent's
+ * re-ask — the settled part itself can't be re-resolved).

+/**
+ * The Agenta OAuth connect flow for a `request_connection` client tool (#4920), extracted from
+ * ConnectToolWidget so two surfaces share ONE implementation without double-settling:
+ *  - the InteractionDock card (composer region) owns the LIVE parked call's actions — Connect,
+ *    "Not now" (decline), Cancel — mirroring ApprovalDock's "dock acts, inline marks" contract;
+ *  - the inline transcript chip keeps the post-settle states (result chip + Retry, which re-runs
+ *    the OAuth with `settleParkedCall=false` to prime the vault for the agent's re-ask).
+ *
+ * It runs the existing connection machinery (`useToolsConnections` → `POST /tools/connections/`,
+ * then a popup on the returned `redirect_url`) and settles the parked call with a **reference,
+ * never a secret**: the runner re-resolves the credential from the project vault on resume.
+ *
+ * Security (hard requirement, design §"Security"): the popup posts back a `tools:oauth:complete`
+ * message; we trust it ONLY when `event.origin` equals the Agenta API origin (the callback page's
+ * origin) and the payload shape matches. Everything else is dropped. The callback also tags the
+ * message with the connection's `slug`/`integration`, so when several connect flows are live at
+ * once each settles only on its OWN completion (never on a sibling's).
+ *
+ * Settle on every terminal path (design §"Settle on every path"), so the run never hangs:
+ *   success → {connected:true, integration, slug} · decline → {connected:false, reason:"declined"}
+ *   · cancel/abandon → {connected:false, reason:"cancelled"} · timeout → {connected:false,
+ *   reason:"timeout"} · failure → errorText.
+ *
+ * Two instances can be mounted for the SAME parked call (dock + inline marker). `meta.settled`
+ * guards every live-settle path in addition to the per-instance `settledRef`, so an instance that
+ * didn't perform the settle can never fire a second `addToolOutput` for it.

Subject: [PATCH 090/139] fix(frontend): drive latest-edited symlink + open
 nested file links in Files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two drive UX bugs on the chat/config file surfaces:

- The summary "latest edited files" fallback listed the cwd top level, which
  includes the `agent-files` fold SYMLINK — so it surfaced the bare symlink row
  instead of real files. The full drive already drops it; the summary didn't.
  Added one shared `isAgentFilesFold(path)` predicate, applied in the full drive
  and both summary lists so the fold marker is dropped consistently.

- File mentions in a reply only opened in Files when written as inline code; a
  markdown link `[x](path)` went straight to a new tab, so nested / `NN-name/`
  paths (which the model tends to emit as links) never reached the resolver.
  `Anchor` now routes a RELATIVE href through the same file resolver: a real
  drive file becomes the in-Files chip, and a real URL / fragment / non-file
  falls back to the plain external link.

Fixes #5480
Fixes #5481

Subject: [PATCH 091/139] fix(api): exclude degraded agent-files symlink marker
 from drive archive

The drive folds the artifact's agent mount into the session drive under an
`agent-files/` symlink the runner creates in the cwd. geesefs degrades that
symlink to a 0-byte OBJECT named `agent-files` in the cwd store (runner
comment: "geesefs silently degrades symlinks to empty files across remounts").

"Download all" archives the cwd mount and the folded agent mount as separate
sources. The cwd `agent-files` object was archived as a FILE, colliding with
the `agent-files/` DIRECTORY the agent-mount source contributes. On extraction
the file blocks the directory, so the agent's files were dropped from the zip.

`build_archive_work_list` now skips the bare `agent-files` fold marker, the
same entry the frontend display already filters (`isAgentFilesFold`). The real
content ships from the agent-mount source under `agent-files/`. Added a unit
test.

Fixes #5482

Subject: [PATCH 093/139] fix(onboarding): scope agent-list cache writes to the
 current project

Address CodeRabbit review on #5525.

The seed/invalidate predicate only checked the search-term slot of the
query key, so creating an agent prepended its row into every cached
project's list and refetched all of them. It now matches the project id
too, carried on CreatedAgentSeed.

A failed agents-list fetch also counted as a confirmed empty list, which
could send someone who already has agents into onboarding. First-run now
requires a successful, fresh, empty result; an error falls through to
agent-home instead of holding the loader forever.

Subject: [PATCH 095/139] fix(frontend): keep dead-end nav live when the
 project already has agents

Starting a new agent puts an existing user into an onboarding session, and the
sidebar greyed out Agents, Evaluation runs and Annotation Queues for the whole
session. Those users watched their own agents sit listed under a disabled
parent, with no way to click through.

deadEndNavDisabledAtom asked "is onboarding running" when it meant "would this
page be empty". It now also requires the project to have no agents. The agent
list is read inside the guard, never above it, so the query stays untracked and
unfetched whenever onboarding is off, matching what gatedSidebarSource does for
the lazy submenu.

Subject: [PATCH 096/139] feat(frontend): group settings by scope and add a
 personal feature flags tab

Settings tabs now declare which scope they belong to (project, organization or
personal) and the sidebar renders them under those headings, with a new
Organization General tab for renaming, transferring and deleting an org.

Adds a Feature Flags tab holding two per-user switches, both stored per user in
local storage: one turns the playground session inspector on, the other
overrides the simplified navigation chosen at signup. The nav override sits in
front of the durable signup default (override ?? default), so an existing user
who wants the simplified nav, or a new user who wants the full one, can say so
without touching the signup-era value. The session inspector is now off unless
its flag is on, in both the chat slice and the panel button.

Also updates the simplify-nav design workspace to match.

Subject: [PATCH 097/139] fix(frontend): stop a failed org delete from escaping
 as an unhandled rejection

antd passes onOk straight to the OK button's onClick, so the awaited
mutateAsync in handleDelete rejected into nothing when the backend refused
the delete. The mutation's onError already shows the message, so catch and
return instead of letting the rejection escape.

Subject: [PATCH 100/139] fix(frontend): fold the agent mount into the drive
 summary fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The summary's recents fallback listed only the cwd mount root, so the
`agent-files` symlink surfaced as a row (#5480) with nothing behind it.
Filtering that marker out of the record-log list alone missed the list that
actually showed it, and would have left the agent's files absent entirely.

Replace the fold-only predicate with one `isListableDrivePath` — runner
plumbing plus the fold marker — used by every drive list AND by the
`hasVisibleRecords` gate, so the gate can no longer withhold the fallback over
a row the list then drops. List the agent mount's root alongside the cwd root,
presented under `agent-files/` exactly as the full drive folds it, so dropping
the marker surfaces the files it stood for instead of hiding them.

Keep the markdown `components` map a module constant: adding the anchor inline
rebuilt it every render, which the map is hoisted specifically to avoid on a
renderer that re-renders per streamed token. Split the anchor so only a
relative href subscribes to the drive resolver.

Subject: [PATCH 101/139] fix(api): resolve zip-namespace collisions when
 merging drive mounts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"Download all" merges several mounts into ONE zip (cwd at the root, the agent
mount under `agent-files/`). A zip carries no directory entries — `a/b` implies
the directory `a` — so a FILE member named `a` blocks it and everything under
`a/` is lost on extraction. An object store holds `a` and `a/b` side by side
happily, so the merged namespace can contain a pair a zip cannot represent.

That is the shape of #5482: geesefs degrades the runner's `agent-files` symlink
into a plain object in the cwd store, which archived as a file shadowed the
`agent-files/` directory the folded agent mount contributes.

`build_archive_work_list` now runs the merged list through
`_resolve_zip_namespace`: a member shadowed by a directory is dropped, and a
duplicate path keeps the first source. This fixes the reported bug by the
invariant rather than by name, whatever the degraded object's size, and guards
the whole collision class.

The degraded link is also skipped up front, scoped to the cwd mount root — the
one path the runner reserves (it unlinks whatever else sits there on attach), so
a real `agent-files` file anywhere else, including at the agent mount's own
root, still ships. Without that, an empty agent mount would leave the marker in
the zip as a phantom file the drive itself hides.

Fixes #5482

From: Arda Erzin <ardaerzin@gmail.com>
Date: Wed, 29 Jul 2026 13:52:06 +0300
Subject: [PATCH 102/139] [refactor] Single source of truth for trace span
 types (#5465)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* chore(frontend): exclude tests from app tsconfigs

The playwright suites are owned and type-checked by the tests workspace,
which holds the @playwright/test dependency; tests/manual scripts import
state modules that no longer exist.

* fix(frontend): restore removed types and repair stale imports

- Restore Parameter, CorrectAnswer and _EvaluationScenario to lib/Types.ts
  (removed by cleanup while consumers remained)
- Re-export MetricColumnDefinition from the EvalRunDetails table barrel
- TooltipButtonProps was renamed EnhancedButtonProps; statusMap moved to
  @agenta/entity-ui/variant
- Synthesize full Parameter objects in UseApiContent

* fix(frontend): resolve high-count tsc error clusters

- useRunMetricData: type selection as the unwrapped value, not the atom
- Webhook builders: narrow WebhookFormValues union before field access
- filtersAtom: accept updater functions in the write signature
- Organization settings: drop stale react-query v4 useErrorBoundary and
  migrate setQueriesData to the v5 filters shape
- evaluations/utils: surface variantId from invocation metadata
- PreviewTableRow: add index signature required by InfiniteTableRowBase

* chore(frontend): add tsc error inventory

* fix(frontend): type-check EvalRunDetails layer; oss tsc 422->347

Mirrors the vetted WP-4e-2a in-place fixes from fe-chore/move-evals-to-packages
(adapted to OSS import paths) plus new fixes for the component layer:

- restore PreviewTestCase to lib/Types; re-export MetricProcessor/MetricScope
- add "input" to EvaluationColumnKind (backend mapping emits it) and type the
  visibility-label column extension in buildPreviewColumns
- recharts v3 API drift in EvaluatorMetricsChart (TooltipContentProps, tuple
  radius, MetricStripEntry contextual typing)
- widen evaluationType to EvaluationRunKind; type query atoms as nullable
- latent runtime bugs typed as-is per WP-4e-2a convention (applyAggregatesToRaw,
  metricProcessor ReferenceErrors, dead metric-group branches) - flagged, not fixed

* fix(entities,entity-ui): updater-style refresh atom and optional variant id

- createPaginatedEntityStore: refreshAtom/actions.refresh accept an optional
  value or updater (bare set() still bumps the counter) - clears the
  'Expected 0 arguments' cluster across testset modals and other consumers
- EnvironmentStatus: variant.id optional; the component already guards it

* fix(frontend): type-check observability, drawers, playground, onboarding layers; oss tsc 347->105

Parallel per-area pass, behavior-preserving throughout (latent runtime bugs are
typed as-is with NOTE comments per the WP-4e-2a convention, not silently fixed):

- TraceSpanNode OSS<->entities dual-type: aligned at every crossing with
  documented boundary casts (16 errors -> 0); annotations field added to the
  OSS node (drawer stores attach it at runtime)
- SharedDrawers: broken SessionDrawerButton imports repaired, JSON-schema
  access typed, null-safety in SelectEvaluators/AnnotateDrawer, drawer
  payload/ref/label types aligned with runtime
- observability: extended-column types for custom antd props, TraceRow/
  SessionRow InfiniteTableRowBase conformance, traceTabsAtom updater support,
  ag-attributes selector typing at the producer
- playground/url-state: removed drifted local duplicates of package types,
  eagerAtom->atom where deps are sync, modal/store prop alignment
- onboarding/testsets/org: updater-widened widget UI atom, tour placement
  vocabulary fix, OnboardingLoader next/dynamic compat, org provider API
  types matched to the backend wire shape (settings/flags dicts)
- EvalRunDetails remainder: WP-4e-2a-vetted atom fixes adapted, recharts v3
  formatter/content signatures, stale import paths repointed

Flagged for triage (typed as-is): AddToTestsetDrawer trace draft discard/
update call missing molecule actions; orphaned SessionDrawerButton

* chore(frontend): update tsc inventory with final counts

* fix(frontend): type-check InfiniteVirtualTable root + cross-cutting patterns; oss tsc 105->82

- InfiniteVirtualTable: canonical ExtendedColumnType exported from the barrel
  (three local extended-column copies repointed as aliases); pure read fn for
  columnHiddenKeys (write path reconciles versions); memo generic preservation;
  onRow/getRowProps/rowSelection.fixed aligned with antd 6
- antd v6 PopoverStylesType 'body' drops typed as-is (2 sites, existing pattern)
- React 19: JSX.Element -> ReactElement in RequireWorkflowKind
- AgentaNodeDTO: trace_id/span_id added (backend SpanDTO sends them)
- Org.default_workspace: list endpoint strips it - both lookups are latent
  dead code, typed as-is with comments
- FiltersPreview: operatorLabel is a display string, not the operator union

* fix(ui,entities): drill-in slot types, table selection/locale props, windowing export

- DrillInUIContext: EditorProvider/SharedEditor slots typed with the real
  component prop types instead of a hand-written subset (root cause of the
  OSS provider assignment errors)
- InfiniteVirtualTable: rowSelection.fixed accepts antd FixedType; locale
  accepted (not yet forwarded - flagged); Editor barrel exports CodeLanguage
- workflow barrel exports WorkflowRevisionWindowing

* fix(frontend): type-check remaining long tail; oss+ee tsc 0 errors

Wave-2 parallel pass over the final ~105 OSS + 11 EE-only errors, behavior-
preserving throughout (latent bugs typed as-is with NOTE comments per the
WP-4e-2a convention):

- Evaluators/Evaluations: generic evaluator filtering, chart datum typing
- pages/evaluations: NewEvaluation modal props retyped to entities-package
  shapes (stale legacy Types imports dropped); antd 6 tabPlacement vocabulary
- Testcases/Testsets/Deployments: canonical ExtendedColumnType adoption,
  dataset-store variance via Pick<...,'hooks'>
- DrillInView/EditorViews: TMode narrowing via consts, Format|CodeLanguage
  state union, html format menu typing
- app-shell misc: services/state/pages sweep with backend-verified API types
- EE Billing + misc EE-only files

Latent bugs surfaced and typed as-is (chips filed where actionable):
workspace rename sends invalid org PATCH body; SessionInspector reads
status.code the backend never sends; axios.isCancel dead on created
instance; invite accept can interpolate undefined ids

* chore(frontend): inventory final - oss and ee tsc at zero

* chore(frontend): fail builds on TypeScript errors

Both apps are at zero tsc errors; flip ignoreBuildErrors to false so
next build guards the baseline. Verified: full oss and ee builds pass
with the gate on.

* refactor(frontend): single source of truth for span types

The OSS tracing module declared its own TraceSpan/TraceSpanNode plus four
TypeScript enums that mirrored the zod schemas in @agenta/entities. The two
were structurally equivalent but nominally incompatible, so every crossing
needed a cast (7 of them, added in #5464 as documented scar tissue).

- oss/src/services/tracing/types now owns only TraceSpanNode (entities node
  plus the annotations the drawer stores attach) and GenerationDashboardData;
  consumers import span types from @agenta/entities/trace directly, per the
  app-layer no-re-export rule
- 25 enum value usages become string literals; StatusCode values were already
  identical, SpanCategory differed only in the catch-all
- all 7 boundary casts removed

Fixes a live crash: AGE-3788 canonicalised the backend catch-all from
"undefined" to "unknown", but spanTypeStyles was still keyed "undefined" and
both consumers destructure the lookup, so any span typed "unknown" threw a
TypeError in the observability table and trace tree. The record is now keyed
by SpanCategory (exhaustive, so a new backend category fails the build) with a
fallback at both call sites.

Nullability now matches the payload: entities declares | null where the
backend sends null, so NodeNameCell/StatusRenderer/TimestampCell props and
ScannedExportRow were widened rather than cast.

* refactor(entities): derive ScannedExportRow from the span schema

Review follow-up on the export ETL row contract.

ScannedExportRow hand-redeclared five span fields, and this branch widened all
five to `| null` to make TraceSpanNode assignable. Only three needed it: the
schema declares trace_id and span_id required and non-null, so widening those
two moved the contract away from the source of truth in the one file this PR
was meant to unify.

Pick the four span fields from TraceSpan instead. Same assignability for the
caller, but the contract can no longer drift.

That widening was what made the dedup collapse CodeRabbit flagged expressible:
rows missing both ids all hashed to the fallback `trace_id:parent_id:start_time`,
so a page of them deduped down to one row. Not reachable from the tracing API
(zod validates both ids at the boundary), but the fallback was wrong on its own
terms — it also collapsed sibling spans sharing a parent and start_time. Dedup
may only drop what it can prove is a repeat, so a row with no identity is now
passed through undeduped: for an export, a duplicate row beats a dropped one.

Also shortens the span-types comment to the one-line repo rule.

Test added for the no-identity path; it fails on the old key (1 row, not 3).

Subject: [PATCH 103/139] [refactor] Drop duplicate EvaluationRun type, align
 step-reference shape (#5466)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* chore(frontend): exclude tests from app tsconfigs

The playwright suites are owned and type-checked by the tests workspace,
which holds the @playwright/test dependency; tests/manual scripts import
state modules that no longer exist.

* fix(frontend): restore removed types and repair stale imports

- Restore Parameter, CorrectAnswer and _EvaluationScenario to lib/Types.ts
  (removed by cleanup while consumers remained)
- Re-export MetricColumnDefinition from the EvalRunDetails table barrel
- TooltipButtonProps was renamed EnhancedButtonProps; statusMap moved to
  @agenta/entity-ui/variant
- Synthesize full Parameter objects in UseApiContent

* fix(frontend): resolve high-count tsc error clusters

- useRunMetricData: type selection as the unwrapped value, not the atom
- Webhook builders: narrow WebhookFormValues union before field access
- filtersAtom: accept updater functions in the write signature
- Organization settings: drop stale react-query v4 useErrorBoundary and
  migrate setQueriesData to the v5 filters shape
- evaluations/utils: surface variantId from invocation metadata
- PreviewTableRow: add index signature required by InfiniteTableRowBase

* chore(frontend): add tsc error inventory

* fix(frontend): type-check EvalRunDetails layer; oss tsc 422->347

Mirrors the vetted WP-4e-2a in-place fixes from fe-chore/move-evals-to-packages
(adapted to OSS import paths) plus new fixes for the component layer:

- restore PreviewTestCase to lib/Types; re-export MetricProcessor/MetricScope
- add "input" to EvaluationColumnKind (backend mapping emits it) and type the
  visibility-label column extension in buildPreviewColumns
- recharts v3 API drift in EvaluatorMetricsChart (TooltipContentProps, tuple
  radius, MetricStripEntry contextual typing)
- widen evaluationType to EvaluationRunKind; type query atoms as nullable
- latent runtime bugs typed as-is per WP-4e-2a convention (applyAggregatesToRaw,
  metricProcessor ReferenceErrors, dead metric-group branches) - flagged, not fixed

* fix(entities,entity-ui): updater-style refresh atom and optional variant id

- createPaginatedEntityStore: refreshAtom/actions.refresh accept an optional
  value or updater (bare set() still bumps the counter) - clears the
  'Expected 0 arguments' cluster across testset modals and other consumers
- EnvironmentStatus: variant.id optional; the component already guards it

* fix(frontend): type-check observability, drawers, playground, onboarding layers; oss tsc 347->105

Parallel per-area pass, behavior-preserving throughout (latent runtime bugs are
typed as-is with NOTE comments per the WP-4e-2a convention, not silently fixed):

- TraceSpanNode OSS<->entities dual-type: aligned at every crossing with
  documented boundary casts (16 errors -> 0); annotations field added to the
  OSS node (drawer stores attach it at runtime)
- SharedDrawers: broken SessionDrawerButton imports repaired, JSON-schema
  access typed, null-safety in SelectEvaluators/AnnotateDrawer, drawer
  payload/ref/label types aligned with runtime
- observability: extended-column types for custom antd props, TraceRow/
  SessionRow InfiniteTableRowBase conformance, traceTabsAtom updater support,
  ag-attributes selector typing at the producer
- playground/url-state: removed drifted local duplicates of package types,
  eagerAtom->atom where deps are sync, modal/store prop alignment
- onboarding/testsets/org: updater-widened widget UI atom, tour placement
  vocabulary fix, OnboardingLoader next/dynamic compat, org provider API
  types matched to the backend wire shape (settings/flags dicts)
- EvalRunDetails remainder: WP-4e-2a-vetted atom fixes adapted, recharts v3
  formatter/content signatures, stale import paths repointed

Flagged for triage (typed as-is): AddToTestsetDrawer trace draft discard/
update call missing molecule actions; orphaned SessionDrawerButton

* chore(frontend): update tsc inventory with final counts

* fix(frontend): type-check InfiniteVirtualTable root + cross-cutting patterns; oss tsc 105->82

- InfiniteVirtualTable: canonical ExtendedColumnType exported from the barrel
  (three local extended-column copies repointed as aliases); pure read fn for
  columnHiddenKeys (write path reconciles versions); memo generic preservation;
  onRow/getRowProps/rowSelection.fixed aligned with antd 6
- antd v6 PopoverStylesType 'body' drops typed as-is (2 sites, existing pattern)
- React 19: JSX.Element -> ReactElement in RequireWorkflowKind
- AgentaNodeDTO: trace_id/span_id added (backend SpanDTO sends them)
- Org.default_workspace: list endpoint strips it - both lookups are latent
  dead code, typed as-is with comments
- FiltersPreview: operatorLabel is a display string, not the operator union

* fix(ui,entities): drill-in slot types, table selection/locale props, windowing export

- DrillInUIContext: EditorProvider/SharedEditor slots typed with the real
  component prop types instead of a hand-written subset (root cause of the
  OSS provider assignment errors)
- InfiniteVirtualTable: rowSelection.fixed accepts antd FixedType; locale
  accepted (not yet forwarded - flagged); Editor barrel exports CodeLanguage
- workflow barrel exports WorkflowRevisionWindowing

* fix(frontend): type-check remaining long tail; oss+ee tsc 0 errors

Wave-2 parallel pass over the final ~105 OSS + 11 EE-only errors, behavior-
preserving throughout (latent bugs typed as-is with NOTE comments per the
WP-4e-2a convention):

- Evaluators/Evaluations: generic evaluator filtering, chart datum typing
- pages/evaluations: NewEvaluation modal props retyped to entities-package
  shapes (stale legacy Types imports dropped); antd 6 tabPlacement vocabulary
- Testcases/Testsets/Deployments: canonical ExtendedColumnType adoption,
  dataset-store variance via Pick<...,'hooks'>
- DrillInView/EditorViews: TMode narrowing via consts, Format|CodeLanguage
  state union, html format menu typing
- app-shell misc: services/state/pages sweep with backend-verified API types
- EE Billing + misc EE-only files

Latent bugs surfaced and typed as-is (chips filed where actionable):
workspace rename sends invalid org PATCH body; SessionInspector reads
status.code the backend never sends; axios.isCancel dead on created
instance; invite accept can interpolate undefined ids

* chore(frontend): inventory final - oss and ee tsc at zero

* chore(frontend): fail builds on TypeScript errors

Both apps are at zero tsc errors; flip ignoreBuildErrors to false so
next build guards the baseline. Verified: full oss and ee builds pass
with the gate on.

* refactor(frontend): single source of truth for span types

The OSS tracing module declared its own TraceSpan/TraceSpanNode plus four
TypeScript enums that mirrored the zod schemas in @agenta/entities. The two
were structurally equivalent but nominally incompatible, so every crossing
needed a cast (7 of them, added in #5464 as documented scar tissue).

- oss/src/services/tracing/types now owns only TraceSpanNode (entities node
  plus the annotations the drawer stores attach) and GenerationDashboardData;
  consumers import span types from @agenta/entities/trace directly, per the
  app-layer no-re-export rule
- 25 enum value usages become string literals; StatusCode values were already
  identical, SpanCategory differed only in the catch-all
- all 7 boundary casts removed

Fixes a live crash: AGE-3788 canonicalised the backend catch-all from
"undefined" to "unknown", but spanTypeStyles was still keyed "undefined" and
both consumers destructure the lookup, so any span typed "unknown" threw a
TypeError in the observability table and trace tree. The record is now keyed
by SpanCategory (exhaustive, so a new backend category fails the build) with a
fallback at both call sites.

Nullability now matches the payload: entities declares | null where the
backend sends null, so NodeNameCell/StatusRenderer/TimestampCell props and
ScannedExportRow were widened rather than cast.

* refactor(frontend): drop duplicate EvaluationRun, align step-reference shape

usePreviewEvaluations declared its own EvaluationRun while
@agenta/entities/evaluationRun already had the canonical zod-derived one.
The local copy over-declared requiredness (name/description/status/meta/flags
as non-null) where the schema says the backend can send null, so #5464 had to
hand-add updated_at to keep it current. Deleted it; the two importers and the
hook now take the type from the package.

Swapping surfaced drift inside @agenta/entities itself: the step-reference
shape was redeclared three times with different types. The core zod schema has
{id, slug?: string|null, version?: number|null}, while the ETL RunStep said
slug?: string and version?: STRING, and ColumnGroup.refs said id?: string.
Both now reference the exported EvaluationRunStepReference from the validated
schema. CandidateRun.status widened to match.

Scoped out, with reasons:
- PreviewTestset is NOT the entities Testset (different endpoint shape: it
  carries slug plus embedded data.testcases; entities Testset is lean
  metadata). PreviewTestCase does match Fern TestcaseOutput, but entities has
  no canonical testcase entity type to route it through yet.
- OrganizationProvider has no entities domain at all, and the response settings
  is a free-form dict while Fern's SsoProviderSettingsDto models create-input.
  Creating a domain for one interface is disproportionate.

* refactor(entities): derive ScannedExportRow from the span schema

Review follow-up on the export ETL row contract.

ScannedExportRow hand-redeclared five span fields, and this branch widened all
five to `| null` to make TraceSpanNode assignable. Only three needed it: the
schema declares trace_id and span_id required and non-null, so widening those
two moved the contract away from the source of truth in the one file this PR
was meant to unify.

Pick the four span fields from TraceSpan instead. Same assignability for the
caller, but the contract can no longer drift.

That widening was what made the dedup collapse CodeRabbit flagged expressible:
rows missing both ids all hashed to the fallback `trace_id:parent_id:start_time`,
so a page of them deduped down to one row. Not reachable from the tracing API
(zod validates both ids at the boundary), but the fallback was wrong on its own
terms — it also collapsed sibling spans sharing a parent and start_time. Dedup
may only drop what it can prove is a repeat, so a row with no identity is now
passed through undeduped: for an export, a duplicate row beats a dropped one.

Also shortens the span-types comment to the one-line repo rule.

Test added for the no-identity path; it fails on the old key (1 row, not 3).

Subject: [PATCH 104/139] refactor(ui): unify extended column type, clear
 dual-copy imports

Prep for retiring the duplicate InfiniteVirtualTable in oss/src/components
(55 files, a strict subset of the 67-file @agenta/ui copy).

The two copies had grown parallel abstractions for the same concept: the
package's ExtendedColumn/ExtendedColumnProps and an ExtendedColumnType added
to the OSS copy. Their bases were already equivalent (ColumnsType[number] IS
ColumnType | ColumnGroupType), so the package type just gained the three props
it lacked (defaultHidden, maxWidth, exportEnabled) and the OSS type is now an
alias of it.

Three files imported BOTH copies at once (TestcasesTableShell,
getObservabilityColumns, getSessionColumns); each needed only the column type
from the OSS side, so they now take it from the package. No file imports both
copies anymore.

Subject: [PATCH 105/139] refactor(ui): delete duplicate InfiniteVirtualTable,
 migrate to @agenta/ui
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The library existed twice: 55 files in oss/src/components/InfiniteVirtualTable
(a strict subset) and the canonical 67-file copy in @agenta/ui. Fixes to
either had to be applied to both — this session alone hit that with the
rowSelection.fixed widening and the ExtendedColumnType consolidation.

- Migrated all 33 app consumers from @/oss/components/InfiniteVirtualTable to
  @agenta/ui/table (the barrel already re-exported every symbol they used).
- Deleted the 55-file OSS copy.
- Package exports ColumnVisibilityNodeMeta / ColumnVisibilityNodeMetaResolver
  (needed by a migrated consumer).

Preserved the export permission gate. The retired OSS shell computed
exportEnabled = enableExport && canExportData internally; the package shell has
no permission check and defaults enableExport=true. The two consumers that
relied on the implicit gate (EvalRunDetails/Table.tsx,
EvaluationRunsTablePOC/.../EvaluationRunsTable/index.tsx) now pass
enableExport={canExportData} explicitly. tsc could not have caught this — both
sides are boolean.

TestsetsTable needed two behavior-preserving adjustments where the package
types are wider: String(record.key) at two Set<string>/string[] lookups (keys
are UUIDs, so a no-op) and 'as never' on the invariant datasetStore generic
(mirrors DeploymentsTable).

Subject: [PATCH 106/139] chore(deps): sync web/pnpm-lock.yaml with
 next@15.5.21 in web/ee

web/ee/package.json was bumped to next@15.5.21 by #5533, but the
lockfile wasn't regenerated, so every PR targeting this branch fails
`pnpm install --frozen-lockfile` in CI regardless of what it changes.

Subject: [PATCH 107/139] fix(api): keep raw_path in sync with path in the
 prefix middleware

The prefix strip and the trailing-slash alternate-form lookup both
mutated `path` but tried to mirror that onto `raw_path` with fragile
byte-level heuristics: a literal `b"/api"` check that a percent-encoded
prefix (`/%61pi/...`) never matches, and an ascii-encode("ignore") that
silently drops non-ASCII bytes. Either case left raw_path stale or
corrupted relative to the routed path.

Re-derive raw_path from the final normalized path instead of tracking
it in parallel, so the two can never diverge.

Subject: [PATCH 108/139] chore(frontend): remove dead SessionDrawerButton
 copied from TraceDrawer (#5457)

The component was never adapted to sessions: it still targeted the trace
drawer atoms, resolved a trace_id from a playground result, and had no
importers. The session drawer is opened via openSessionDrawerAtom from the
URL state layer instead. Also removes SessionDrawer/types.ts, which held
only the button's props interface.

Subject: [PATCH 109/139] [refactor] Delete duplicate InfiniteVirtualTable,
 migrate to @agenta/ui (#5471)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(ui): unify extended column type, clear dual-copy imports

Prep for retiring the duplicate InfiniteVirtualTable in oss/src/components
(55 files, a strict subset of the 67-file @agenta/ui copy).

The two copies had grown parallel abstractions for the same concept: the
package's ExtendedColumn/ExtendedColumnProps and an ExtendedColumnType added
to the OSS copy. Their bases were already equivalent (ColumnsType[number] IS
ColumnType | ColumnGroupType), so the package type just gained the three props
it lacked (defaultHidden, maxWidth, exportEnabled) and the OSS type is now an
alias of it.

Three files imported BOTH copies at once (TestcasesTableShell,
getObservabilityColumns, getSessionColumns); each needed only the column type
from the OSS side, so they now take it from the package. No file imports both
copies anymore.

* refactor(ui): delete duplicate InfiniteVirtualTable, migrate to @agenta/ui

The library existed twice: 55 files in oss/src/components/InfiniteVirtualTable
(a strict subset) and the canonical 67-file copy in @agenta/ui. Fixes to
either had to be applied to both — this session alone hit that with the
rowSelection.fixed widening and the ExtendedColumnType consolidation.

- Migrated all 33 app consumers from @/oss/components/InfiniteVirtualTable to
  @agenta/ui/table (the barrel already re-exported every symbol they used).
- Deleted the 55-file OSS copy.
- Package exports ColumnVisibilityNodeMeta / ColumnVisibilityNodeMetaResolver
  (needed by a migrated consumer).

Preserved the export permission gate. The retired OSS shell computed
exportEnabled = enableExport && canExportData internally; the package shell has
no permission check and defaults enableExport=true. The two consumers that
relied on the implicit gate (EvalRunDetails/Table.tsx,
EvaluationRunsTablePOC/.../EvaluationRunsTable/index.tsx) now pass
enableExport={canExportData} explicitly. tsc could not have caught this — both
sides are boolean.

TestsetsTable needed two behavior-preserving adjustments where the package
types are wider: String(record.key) at two Set<string>/string[] lookups (keys
are UUIDs, so a no-op) and 'as never' on the invariant datasetStore generic
(mirrors DeploymentsTable).

Subject: [PATCH 110/139] feat(agent-chat): gate voice input behind
 NEXT_PUBLIC_AGENT_VOICE_INPUT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A voice message rides along as an audio attachment, which the agent service
does not accept yet. Hide the whole surface — the composer mic (both dictation
and voice-message modes), the recording takeover, and the mic-permission notice
— behind an opt-in flag so the branch can land without exposing it.

The recorder hook stays mounted but is inert: nothing can call start(), so the
drag/drop and paste guards it feeds are always false, matching pre-branch
behavior. The editor's dictating lock is gated too, leaving the shortcut hints
untouched when the flag is off.

Subject: [PATCH 111/139] chore(deps): bump axios from 1.16.0 to 1.18.0 in
 /web/packages/agenta-shared

Rebuilt on top of current release/v0.106.1 instead of merging the
stale dependabot branch forward (it was based on old v0.105.8 and
merging pulled in unrelated historical diff noise). Includes the
lockfile regen the original PR was missing, which would otherwise
fail pnpm's frozen-lockfile check in CI.

Axios 1.17-1.18 include real security fixes: stripping sensitive

Subject: [PATCH 112/139] chore: allowlist two benign gitleaks findings

Both are pre-existing, already-merged, and not real secrets:
- .github/workflows/16-website-production.yml: PostHog's public
  client-side key (meant to be public, not a credential).
- agenta-entities' secret-persist-redaction.test.ts: a literal fake
  string ("sk-live-abc123") used to test redaction logic.

Without this, any push whose commit range spans these two commits
(e.g. a long-stale branch being caught up to this base) fails the
gitleaks pre-push hook on findings that were never real secrets.

Subject: [PATCH 113/139] fix(web): collapse dual axios resolution, fixing the
 broken agenta-web build

release/v0.106.1's agenta-web Docker build is currently failing:
`next build`'s internal type-check errors on src/state/access/atoms.ts
with an AxiosRequestConfig type mismatch. Root cause: PR #5428 bumped
axios to 1.18.0 in agenta-shared only, while oss, ee, tests, and the
repo-wide pnpm.overrides pin stayed on 1.16.0 (and agenta-entities /
agenta-entity-ui floated on a wide peer range that pnpm kept resolving
to the old version). Two structurally-incompatible AxiosRequestConfig
declarations then collided in the same tsc program.

Fix: align every consumer on axios 1.18.0 - oss, ee, tests package.json
pins, the peer ranges in agenta-entities/agenta-entity-ui (tightened to
>=1.18.0 so pnpm can't silently keep resolving 1.16.0), and the
repo-wide pnpm.overrides floor. pnpm why axios now shows a single
resolved version across the whole workspace.

Verified: tsc --noEmit clean (0 errors) for both oss and ee, and
`pnpm --filter @agenta/oss run build` (the exact command failing in
CI) completes successfully.

Subject: [PATCH 114/139] feat(agent-chat): gate uploads + attachments behind
 NEXT_PUBLIC_AGENT_FILE_UPLOADS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The composer→model attachment delivery contract is still open on the backend, so
hide every entry point this branch adds behind an opt-in flag and let the branch
land dark.

Off (the default) restores the pre-branch surface: the composer attach button is
dead again ("coming soon"), the attachment preview drawer never mounts, and the
drive loses its upload button, drop-to-upload on folders/panes, and drop-to-stage
on both recents peeks. `canUpload` in DriveExplorer was already the single switch
for the drive half, so the flag folds into it; useDriveDrop gains an `enabled`
escape so its window-level drag listeners don't mount either.

Paste and drag-to-attach on the composer predate this branch and stay on.

Subject: [PATCH 116/139] Reapply "fix(web): collapse dual axios resolution"

Re-applies commit 5c1d0deeb2, previously reverted at c093bbc396.
Aligns axios at 1.18.0 across oss, ee, tests, agenta-entities, and
agenta-entity-ui (plus the repo-wide pnpm.overrides pin), so only one
axios version resolves workspace-wide instead of the 1.16.0/1.18.0
split left by #5428's partial bump. That split broke `next build`'s
type-check (AxiosRequestConfig from two different axios instances
treated as incompatible types), which was failing the agenta-web
Docker image build on this branch.

Verified: tsc --noEmit clean (0 errors) for both oss and ee, pnpm why
axios shows a single resolved version workspace-wide, and
`pnpm build-oss` completes successfully (7/7 tasks).

Subject: [PATCH 118/139] [fix] Bound the session-records fetch and consume the
 persist-drop signal (#5501)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(runner): bound the records fetch and consume the persist-drop signal

Two small robustness gaps in the reconstruction pipeline:

- fetchSessionRecords sits on the turn's critical path (the prompt waits on it), but had no
  timeout, so a stalled query would wait on Undici's long request-level timeout instead of
  failing fast to the inbound-history fallback. Add an env-tunable AbortSignal.timeout (5s
  default).
- takePersistFailures had no caller: in durable mode a dropped record was counted into a
  per-session map that nothing read, so the signal was lost and the map grew unbounded.
  Consume it at the turn-end drain (flush) — warn when the durable log is incomplete and
  clear the counter.

* fix(runner): read numeric env config against an explicit domain

The records-fetch timeout added in this branch could resolve to a value that aborts the
request instantly — the opposite of what the bound is for. AGENTA_SESSIONS_RECORDS_QUERY_
TIMEOUT_MS=0.5 passes the `> 0` check, truncates to 0, and AbortSignal.timeout(0) rejects
before the query completes, silently pinning reconstruction to the inbound-history fallback.
The same read had no ceiling either: above 2^31-1 Node's timer overflows to a 1ms delay, and
above 2^32-1 AbortSignal.timeout throws outright.

That read was the fourth hand-rolled numeric-env parser in the runner, each encoding a
different partial idea of what is valid, and every failure mode degrades toward no protection
at all. State the domain once instead: src/env.ts reads a name as an integer inside [min, max],
truncating before clamping (so a fractional value cannot sneak through as 0) and capping timer
delays at Node's 32-bit ceiling. Unset stays silent; set-but-unusable falls back or clamps and
warns once, since a typo in one env var must not break every run in the process.

Routed through it:
- records-query: the timeout above, floor and ceiling both.
- persist: OPEN_TOOL_TTL_MS carried the same hole in NaN form — junk parsed to NaN and
  setTimeout(fn, NaN) fires at 1ms, collapsing the tool-call coalescing window this file
  exists to maintain. durableMaxRetries gains a ceiling, since each extra attempt doubles
  the worst-case turn-end drain.
- run-limits: drops its private envMs, which accepted 0 (a deadline that trips immediately)
  and had no integer or overflow bound.

Tests: env-num covers each input regime; session-records-query pins the bound at the call
site, which had no coverage at all. Runner unit suite 1277 green, typecheck clean.

* fix(runner): hold the timer domain across derived delays, not just reads

resolveRunLimits derives `idle` as half the total when a misconfigured idle would otherwise be
unreachable. envTimerMs guarantees each limit is at least 1ms, but half of a total sitting at
that floor rounds to 0, and a 0ms idle timer trips the run the moment it is armed — the guard
this branch just added, escaping through a value the env reader never saw.

Guarding the derivation would leave the next one exposed, so the contract moves onto the
output: ResolvedRunLimits now states that every field is armable, and resolveRunLimits
normalizes the whole record before returning it, which covers any future cross-limit
adjustment for free. clampTimerMs is the shared primitive for that — env.ts already owned the
domain for reads, and now exposes it for delays the code computes afterwards (a fraction of
another limit, a backoff, a remaining budget). envInt clamps through the same path, so the
domain has one definition rather than two that can drift.

While wiring it: ±Infinity now clamps to the matching end of the range instead of the floor.
NaN is the only input with no magnitude to clamp toward, and an infinite deadline collapsing
to "fires instantly" is the exact inversion this is meant to prevent.

Tests: the degenerate-total case is pinned in run-limits (it fails with idleMs=0 without the
normalization), clampTimerMs is covered directly. Runner unit suite 1281 green, typecheck clean.

Subject: [PATCH 119/139] chore(repo): consolidate committed agent skills under
 .agents/skills and publish four local skills

Move the five committed .claude-native skills to .agents/skills, publish
write-issue, implement-feature, plan-feature, and style-editing, and make the
.gitignore allowlist match the full tracked set. The .claude symlinks for
these skills land in the follow-up commit.

+description: Drive a researched and planned feature to a landed, tested change. Use after plan-feature has produced a docs/design/<project>/ workspace and the user says "implement it", "build the plan", "run the plan", or "let's ship this". Orchestrates refresh-plan, implement, review, a debug-local-deployment loop, and a test loop across the daytona / local-pi / claude x SDK / UI matrix, then documentation and a GitButler stacked branch. The orchestrator stays in the loop and spins narrow subagents for each phase.
+allowed-tools: Read, Edit, Write, Grep, Glob, Bash, Agent, Task
+user-invocable: true
+---
+
+# Skill: Implement a Planned Feature
+
+This is the step after `plan-feature`. Research is done and a plan exists. Your job is to
+turn that plan into a change that builds, runs end to end, and stays green, then to write it
+up and put it on a branch.
+
+You are the orchestrator. You do not write the whole feature yourself in one pass. You drive
+the feature through phases and spin a narrow subagent for each phase, handing it full
+context. You stay in the loop between phases, read each result, update the plan, and decide
+the next move. This mirrors the subagent discipline in the `agent-workflows-qa` skill: every
+fixer is followed by a reviewer, and every fix is followed by a retest.
+
+## Precondition: a plan workspace exists
+
+The feature must already have a planning workspace from `plan-feature`:
+
+- `docs/design/<project>/` with at least `README.md`, `context.md`, `plan.md`,
+  `status.md`, and `research.md`.
+
+If there is no such workspace, stop. Run `plan-feature` first. Do not improvise a plan inside
+this skill. `status.md` is the source of truth for progress and stays current through every
+phase below.
+
+## The chain at a glance
+
+```
+plan-feature  ->  [ implement-feature ]  ->  write-pr-description (when you open the PR)
+                        |
+   Phase 0  refresh the plan (status.md is truth)
+   Phase 1  implement        (implementer subagent: smallest correct change)
+   Phase 2  review           (reviewer subagent: root cause, no regression)
+   Phase 3  debug end to end (debug subagent, loop)   -> debug-local-deployment skill
+   Phase 4  tests            (test subagent, loop)     -> agent-workflows-qa + agent-replay-test
+   Phase 5  document + PR draft (docs subagent)        -> write-docs + write-pr-description (Context + Scope/risk + How to QA)
+   Phase 6  stacked branch   (GitButler)               -> but (publish Phase 5 PR body on push)
+```
+
+## Keep the orchestration console current (when the effort has one)
+
+If this work is tracked in an `orchestration-console` project (see the `orchestration-console`
+skill), mirror progress to the console as you go, so the user reads status and answers decisions
+from the dashboard instead of chat. The console never replaces the PR review flow; it links to
+it. The hooks map onto the phases above:
+
+- **Start of every turn:** `console pending --project <p>` and act on the user's answers and
+  notes first, then `console decision lock` each one you acted on.
+- **Phase 0:** `console task add` one task per slice; `console message` what this run attempts.
+- **Phase 1:** `console task set <slice> --status running --owner <impl-agent>`.
+- **Phase 2:** on changes requested, a `console message --ref task:<slice>`.
+- **Phase 3-4:** when a debug/test loop stalls and you would escalate to the user, raise a
+  `console decision add` (the stuck state + options + your rec) instead of burying it in chat.
+  This is the highest-value hook: it is exactly the "route / debug" decision that gets lost today.
+- **Phase 5:** `console task set <slice> --status in-review --pr <url>`.
+- **Phase 6:** on push, `console message` with the PR link.
+
+## Phase 0: Refresh the plan
+
+Before any code changes, re-read the workspace and reconcile it with the code as it stands
+now. Plans rot. The repo may have moved since the plan was written.
+
+1. Read `context.md`, `plan.md`, `research.md`, and `status.md`.
+2. Verify the plan's file and symbol citations still exist. Where the code drifted, correct
+   the plan, do not code against a stale map.
+3. Cut the plan into the smallest shippable slices, each one independently reviewable and
+   testable. Record the slice list and the acceptance check for each in `plan.md`.
+4. Update `status.md`: what is done, what this run will attempt, known blockers.
+
+End Phase 0 with a concrete slice to build and a written acceptance check for it.
+
+## Phase 1: Implement
+
+Spin an implementer subagent per slice. Keep it narrow and give it everything it needs to
+work cold:
+
+- the slice goal and its acceptance check from `plan.md`,
+- the exact files and symbols to touch (from the refreshed plan),
+- the repo conventions that apply (the relevant `AGENTS.md`, the area skills),
+- the rule: make the smallest correct change, match the surrounding code, do not refactor
+  next door, do not commit.
+
+When the slice defines or changes an interface or contract — API params, wire fields, config
+schema, tool definition, event payload — apply the `design-interfaces` skill first: classify
+each field by its semantic role (data, config, policy, credentials, routing, metadata,
+protocol context), not the feature it touches, and fix the shape before it ships. The
+reviewer in Phase 2 checks the same lens on any contract the slice moved.
+
+When the slice spans the API or SDK, the subagent runs `ruff format` then `ruff check --fix`
+before reporting done. For frontend slices it runs `pnpm lint-fix` in `web/`. The subagent
+returns a short diff summary and a self-check against the acceptance criterion. You read it.
+You do not trust "done" without the check.
+
+## Phase 2: Review
+
+Every implementation is followed by a review. Spin a reviewer subagent and hand it the diff
+plus the slice goal. Its job is to confirm the change actually solves the slice, find
+regressions, and catch the class of mistake a fixer working alone misses (a Dockerfile `CMD`
+overridden by a compose `command:`, a default that looks right but is read from the wrong
+layer, an edit that the dev stack will not hot-reload).
+
+The reviewer reports: root cause addressed yes or no, regressions, and required changes. If it
+asks for changes, loop back to Phase 1 with its notes. Do not advance with an open review.
+
+Note on `/code-review` (ultrareview): the heavy cloud review is user-triggered and billed, and
+you cannot launch it from here. When the change is large or risky, finish the subagent review,
+then tell the user they can run `/code-review ultra` on the branch for a deeper pass.
+
+## Phase 3: Debug end to end (loop until it works)
+
+A slice is not done when it compiles. It is done when it runs against the live stack. Spin a
+debug subagent that drives the running deployment with the `debug-local-deployment` skill:
+find the live port and compose project, reproduce the path through the playground UI and the
+backend API, read the container logs, and confirm the slice does what the acceptance check
+says.
+
+Loop: run, observe, fix, re-run. Each iteration is a debug subagent that reports what it saw
+and what it changed, followed by a reviewer when it changes code (Phase 2 still applies inside
+the loop). Watch dev-mode reload rules: backend and frontend source hot-reload, but a changed
+`@agenta/*` package or a new dependency needs a restart or rebuild. See
+`debug-local-deployment` for the exact commands.
+
+Exit the loop when the slice works end to end against the live stack. See the loop discipline
+section below for when to stop trying and escalate instead.
+
+## Phase 4: Tests (loop until green across the matrix)
+
+Now make it stay working. Spin a test subagent that improves coverage and runs the suite,
+then loops until green. Use the real project test targets, never throwaway scripts.
+
+For agent-workflows changes, the bar is the QA matrix from the `agent-workflows-qa` skill.
+"Test with daytona / local pi / claude, using both the SDK and the UI" maps to its axes:
+
+- **Environment**: `E1` service + in-process Pi, `E2` service + Rivet local, `E3` service +
+  Rivet Daytona, `E4` local SDK script. E3 is the daytona cell. E1 or E2 is the local-pi
+  cell. E4 is the SDK path.
+- **Harness**: `pi`, `agenta`, `claude`. The claude cell needs an `anthropic` provider key in
+  the target project's vault, and claude always forces the Rivet backend.
+- **Surface**: the SDK (E4, a script that pulls config and runs on the host) and the UI (the
+  playground, driven with the `mcp__chrome-devtools__*` tools against the live deployment).
+
+Force each capability with a token the model cannot guess (a constant inside a code tool, a
+value from `uname -m`, a record only the MCP server has) so a pass proves the capability ran,
+not just that the agent answered. Consult `qa/matrix.md` for which cells are valid before
+testing one. Do not test cells that cannot exist.
+
+When a matrix cell is green and worth keeping green, pin it with the `agent-replay-test` skill:
+capture one real `/run`, redact the volatile fields, and write a replay test that exercises
+the real SDK and service code against the recorded runner response with no live LLM. These run
+cost-free in the default CI lane.
+
+Loop until the suite is green and the targeted matrix cells pass. A capability that is
+advertised but never actually invoked is a fail.
+
+## Phase 5: Document and pre-draft the PR body
+
+When the feature works and stays green, write it up. Spin a docs subagent.
+
+- Update `status.md` to "landed" with what shipped and what was deferred.
+- Update the living docs under `docs/design/<project>/` and, when the feature changes how a
+  user runs or configures the agent, the agent-workflows `documentation/` pages. Use the
+  `write-docs` skill for Agenta voice and structure.
+- If the slice moved an interface, wire field, endpoint, config field, default, harness/backend
+  value, or runtime behavior, run the `keep-docs-in-sync` skill: it maps the change to every
+  doc that describes it (the `documentation/` pages, the interface inventory page AND its index
+  row, the relevant `AGENTS.md`, skills) and enforces one source of truth. A contract change and
+  its docs land in the same PR. Do this inside the same docs subagent.
+- Run a clarity pass with the `style-editing` skill (Williams' principles: real characters as
+  subjects, active voice, old-before-new, cut the throat-clearing, land the strong word last).
+- Carry anything you could not finish into `defer-todo` format so it is not lost.
+- Draft the PR body now, while the change is fresh. Use the `write-pr-description` skill. The body MUST include: a **Context** section (the symptom + why), a **Scope / risk** section (what was not touched, what could regress), and a **How to QA** section with prerequisites, numbered steps, expected result, the exact test command to run, and edge cases. These are the things reviewers always ask for — they belong in the first draft, not after a review round.
+
+## Phase 6: Stacked branch (GitButler)
+
+Put the work on its own lane. This repo runs GitButler, so use `but`, not raw git, and follow
+the repo's gotchas.
+
+1. `but oplog snapshot -m "before <feature> branch"` first. The workspace is usually dirty
+   with other lanes' work, so protect it.
+2. `but status` to see the lanes and pick the parent to stack on.
+3. `but branch new <type>/<feature> --anchor <parent>` to stack on that parent.
+4. Stage only this feature's files to the new lane with `but rub <path> <branch>`, then
+   `but commit <branch> --only -m "..."`. Never run a bare `but commit`, which sweeps every
+   unassigned change in the workspace into the lane.
+5. Stop there unless the user asks to push. When they do, `but push <branch>` then
+   `gh pr create --head <branch> --base <parent-or-main>`. Use the PR body drafted in Phase 5
+   (via the `write-pr-description` skill). Confirm it includes Context, Scope / risk, and the
+   full How to QA section (prerequisites, steps, expected result, test command, edge cases)
+   before creating the PR. End commit messages and PR bodies with the session footer the repo
+   conventions require.
+
+If a file is gitignored (a personal `.claude/skills/*` skill, for example), it will not enter
+the lane. Commit the tracked deliverables and say plainly which files stayed local.
+
+## Multi-agent coordination (when others work in parallel)
+
+This repo often has several agents in one GitButler working tree at once. To avoid tangling
+GitButler and to keep local and remote in sync:
+
+- Read `docs/design/agent-workflows/scratch/agent-coordination.md` first and claim a dated row
+  for your task. Re-read it to see which files other lanes already own.
+- Serialize every `but` write behind the board's BUT-LOCK: take it, write, release it. Never
+  let two `but` mutations run at once across agents.
+- Stage ONLY your task's files to your lane (`but rub <path> <lane>`), then
+  `but commit <lane> --only`. Never a bare `but commit` — it sweeps every unassigned change in
+  the shared tree into your lane. Leave the shared `agent-coordination.md` edits unassigned.
+- Do not edit a file another active agent is mid-change on. If your work and theirs must touch
+  the same file, sequence (let theirs land first); the board serializes commits, not live
+  edits, so concurrent same-file edits corrupt each other.
+- Commit in small, frequent chunks and keep local and remote in sync: push your lane
+  (`but push <lane>`) when a slice is done so origin matches your working tree, and update the
+  PR. Always leave a short "what changed" note (a PR comment, or a board row update) so the
+  next agent and the reviewer are not left re-diffing.
+- Merge into the integration branch (`big-agents`) only when explicitly told.
+
+## Subagent discipline
+
+- Keep each subagent narrow and hand it full context: the goal, the files, the acceptance
+  check, the conventions. A subagent that has to guess produces work you have to redo.
+- Every implementer or fixer is followed by a reviewer. Every fix is followed by a retest. No
+  exceptions.
+- Run independent subagents in parallel (several review dimensions, several matrix cells), but
+  put a barrier where the next phase needs all of the prior results.
+- You synthesize. Subagents return findings, you decide. Do not hand the wheel to a subagent
+  for a design call.
+
+## Loop discipline (do not spin forever)
+
+The debug loop and the test loop can run away. Bound them.
+
+- Set a cap before you start (for example three rounds). If a round makes no progress, stop
+  looping.
+- When stuck, triage with the `agent-workflows-qa` tree: fix-now only for a small change with
+  an obvious home and no design question; otherwise **defer** (write a `defer-todo` finding
+  with a clean repro) or **escalate** to the user (a repo restructure, a security surface, a
+  new config the user must decide). When in doubt between fix-now and defer, defer.
+- Keep `status.md` current at every turn so the next session, or the next agent, can pick up
+  cold.

+name: planner-feature
+description: Create a plan for a feature, and the files required to continue working on it. Use when the user asks for research for a feature or a plan to run it. 
+---
+
+Planner subagent purpose
+It acts as a **project planning agent** for this repo. Its main job is to create and maintain a **planning workspace** under:
+
+- `docs/design/<project-name>/`
+
+This workspace is meant to be shared context for other agents and humans during a feature’s lifecycle.
+
+### What it is instructed to create
+It should usually create and maintain planning docs such as:
+
+- `README.md` — index of the planning folder and file descriptions
+- `context.md` — why the work exists, goals, non-goals, background
+- `plan.md` — high-level execution plan, phases, milestones
+- `status.md` — current progress, blockers, decisions; kept up to date
+- `research.md` — discoveries from codebase exploration, caveats, gotchas
+
+It may also add extra docs if useful, such as:
+
+- `prd.md`
+- `rfc.md`
+- `qa.md`
+- more focused technical docs like `api-design.md`, `data-model.md`, `migration-plan.md`, etc.
+
+### Planning philosophy
+The hidden instructions emphasize that the planning workspace should be:
+
+- **self-contained**
+- **navigable**
+- understandable without reading the whole codebase
+- based on **actual repo research before proposing solutions**
+- continuously updated, especially `status.md` as the source of truth
+
+When the plan defines or changes an interface or contract — API params, wire fields, config
+schema, tool definition, event payload — apply the `design-interfaces` skill to review and
+improve the shape by semantic role: classify each field by what it IS (data, config, policy,
+credentials, routing, metadata, protocol context), not the feature it touches. Do this while
+the contract is still on paper (e.g. `api-design.md`, `data-model.md`), where it is cheapest
+to fix.
+
+### Writing standards (apply while authoring, not as a review pass)
+
+These are hard requirements for every file in the workspace. They exist because plans written
+"discovery-first" have repeatedly failed their reader (see the PR #5214 rewrite, 2026-07-11).
+
+1. **Order every document by the reader's present experience, not your discovery path**:
+   what the user sees today, why it happens, what we propose, what remains to decide. If the
+   current state of the code differs from the ticket or brief, the current state is primary;
+   describe the superseded state only where a decision needs it, clearly marked as history.
+2. **No undefined labels.** Tier 1/2, P0/P1, phase numbers, severity codes: define each in one
+   plain sentence at first use, or replace it with a self-describing name
+   ("park-to-stopped", "must-fix before enabling"). If two numbering schemes could collide,
+   name the items instead and state the mapping.
+3. **No metaphors as bare nouns**: rung, seam, fence/fencing, load-bearing, soak. Say the
+   literal thing.
+4. **Section titles state their content plainly.** Test: the reader predicts the section from
+   the title alone. No teasers, no drama.
+5. **Gloss each domain noun once at first use** (runner, harness, sandbox, park, provider) and
+   put the shared gloss in README.md so later files lean on it. README.md also gives the
+   reading order: which file answers which question.
+6. **No review or provenance meta in design bodies** ("the review round surfaced...",
+   "amended after feedback"). That history lives in status.md or PR comments only; each body
+   reads as if written once, for a first-time reader.
+7. **Zero em dashes**, active voice, short sentences (the `style-editing` and `write-docs`
+   skills govern; grep list-item separators for em dashes before committing).
+
+### Repo/environment guidance included
+The prompt also injects repo-specific guidance, including:
+
+- working directory and repo context
+- coding/testing conventions from repo docs
+- architecture guidance for API and frontend work
+- state management, data fetching, styling, and component patterns
+- when to use specialized skills/tools
+
+### Tooling/behavior constraints
+It is also instructed on how to operate with tools, including:
+
+- use repo-aware file and search tools
+- avoid unsafe/destructive git behavior
+- only commit when explicitly asked
+- use certain skills when tasks match them
+- follow local contributor guidance for linting/formatting/testing
+
+### If helpful
+I can also provide either of these:
+
+1. a **short summary** of the planner prompt  
+2. a **structured outline** of all its sections  
+3. a **sanitized near-template** of what such a planner prompt looks like without exposing hidden internals

+name: style-editing
+description: Apply Joseph Williams' clarity principles when writing or editing prose. Use when drafting technical or business writing, diagnosing unclear sentences, rewriting passive or abstract prose, or any time the user references Williams, "Style: Lessons in Clarity and Grace," or "Style: The Basics of Clarity and Grace."
+---
+
+# Williams' Style: Clarity and Grace
+
+Practical principles from Joseph M. Williams' *Style: Lessons in Clarity and Grace* (and the condensed *Style: The Basics of Clarity and Grace*). Use as a checklist when writing or editing prose that needs to be clear, direct, and reader-friendly.
+
+## Core philosophy
+
+Williams' two foundational claims:
+1. It is good to write clearly.
+2. Anyone can write clearly, if they revise with the right principles in mind.
+
+Skilled writers don't *write* clear sentences. They *revise into* them. Treat first drafts as raw material. Apply these principles in revision passes.
+
+Clarity is reader-first: your job is to make the reader's work easy.
+
+## The two foundational principles
+
+### 1. Characters as subjects, actions as verbs
+
+The grammatical subject of a sentence should name the actual character (the agent doing something). The verb should name what that character does.
+
+When the subject is an abstraction and the verb is weak, the sentence loses energy and clarity.
+
+- Bad: *"There was a decision by the committee to approve the budget."*
+- Good: *"The committee decided to approve the budget."*
+
+- Bad: *"The intention of the team was the implementation of a new policy."*
+- Good: *"The team intended to implement a new policy."*
+
+Diagnostic question for any unclear sentence: **Who is doing what?** If the answer is buried in nouns and prepositions, rewrite so the actor is the subject and the action is the verb.
+
+### 2. Avoid nominalizations
+
+A nominalization is a verb (or adjective) converted into a noun. They drain action from prose.
+
+Common signs:
+- Words ending in -tion, -ment, -ance, -ence, -al, -ity, -ness in subject position
+- Phrases like "make a decision," "conduct an analysis," "give consideration to"
+
+Rewrites:
+- "Make a decision" → "decide"
+- "Conduct an analysis of" → "analyze"
+- "Give consideration to" → "consider"
+- "Reach an agreement" → "agree"
+- "Have a discussion about" → "discuss"
+
+When you spot a nominalization in subject or object position, ask: can I turn it back into a verb and find a real character to do it?
+
+## Voice and emphasis
+
+### 3. Active over passive (with exceptions)
+
+Default to active voice. Use passive only when:
+- The agent is unknown ("My car was stolen.")
+- The agent is unimportant or obvious
+- You need to keep the subject consistent across sentences (cohesion — see below)
+- You want to put the agent at the end of the sentence for emphasis (stress position)
+
+Active voice puts the character first, where the reader expects to find it.
+
+### 4. Stress position: end of sentence carries weight
+
+Readers feel the natural emphasis of a sentence at its end. Put the most important new information there.
+
+- Weak: *"Climate change is the most pressing issue facing humanity, in my opinion."*
+- Strong: *"In my opinion, the most pressing issue facing humanity is climate change."*
+
+- Weak: *"Agenta is the AI reliability layer that closes that gap, fundamentally."*
+- Strong: *"The gap is what Agenta closes."*
+
+When revising, ask: what's the most important word or idea in this sentence? Is it landing in the stress position?
+
+## Cohesion across sentences
+
+### 5. Old before new
+
+Each sentence should start with information the reader already knows (from the previous sentence or shared context) and end with new information. This creates a chain readers can follow effortlessly.
+
+- Choppy: *"Photosynthesis converts sunlight to energy. The Calvin cycle is the second stage of photosynthesis. Carbon fixation happens in the Calvin cycle."*
+- Cohesive: *"Photosynthesis converts sunlight to energy. The second stage of photosynthesis is the Calvin cycle, which fixes carbon."*
+
+In the cohesive version, each sentence picks up where the last one left off.
+
+### 6. Topic strings (consistent subjects across a paragraph)
+
+A paragraph has a "topic string" — the chain of grammatical subjects across its sentences. When the topic string is consistent, the paragraph feels unified. When subjects keep changing, the paragraph feels scattered.
+
+Diagnostic: list the grammatical subject of each sentence in the paragraph. If the list is "team / data / system / users / process / our approach," the paragraph has no topic string. Pick one anchor character (often the most important agent in the paragraph) and rewrite so most sentences share that subject.
+
+This is what passive voice is good for: it lets you keep the same subject across sentences even when the action changes hands.
+
+### 7. Topic + body + close in paragraphs
+
+Each paragraph should:
+- Open with a controlling sentence (the issue or claim)
+- Develop it in the body
+- Close with a sentence that points forward, names the consequence, or summarises
+
+Don't bury the controlling idea in the middle. The opening sets the topic; the close earns the stress position.
+
+## Concision
+
+### 8. Cut what you don't need
+
+Williams' favourite categories of cuts:
+
+**Wordy phrases:**
+- "due to the fact that" → "because"
+- "in order to" → "to"
+- "at this point in time" → "now"
+- "for the purpose of" → "to"
+- "in the event that" → "if"
+- "with regard to" → "about"
+- "the fact that" → usually deletable
+
+**Doublets** (keep one of each pair):
+- "each and every"
+- "first and foremost"
+- "any and all"
+- "true and accurate"
+
+**Empty modifiers:**
+- very, really, basically, actually, literally, essentially, simply, quite, rather
+
+**Throat-clearing openers:**
+- "I think that..."
+- "It should be noted that..."
+- "It is important to remember that..."
+
+**Redundant pairs:**
+- "free gift" (gifts are free)
+- "advance planning" (planning is in advance)
+- "end result" (results are at the end)
+
+### 9. Sentence length: vary it on purpose
+
+Mix short and long sentences. A short sentence after a long one creates emphasis. A run of short sentences in a row gets choppy. A run of long sentences in a row gets exhausting.
+
+Read your prose aloud. The rhythm should breathe.
+
+## Grace (the optional layer)
+
+### 10. Parallel structure
+
+When you list or contrast, use parallel grammatical structure so the reader sees the parallel meaning.
+
+- Bad: *"She likes hiking, swimming, and to bike."*
+- Good: *"She likes hiking, swimming, and biking."*
+
+- Bad: *"The product is fast, reliable, and you can scale it."*
+- Good: *"The product is fast, reliable, and scalable."*
+
+### 11. Balanced sentences
+
+Two parallel halves separated by a comma, semicolon, or colon create rhythm and emphasis.
+
+- *"Demos are easy. Reliability isn't."*
+- *"They iterate on prompts; the system iterates on them."*
+
+Use sparingly. Overused, balance becomes mannered.
+
+### 12. End on the strongest word
+
+When you have a choice, arrange the sentence so the strongest word lands last. The reader's ear hears it as the point.
+
+## Ethics
+
+### 13. Write to others as you'd want them to write to you
+
+Avoid:
+- Jargon that excludes readers who don't share your specialty
+- Hedges that obscure responsibility ("mistakes were made")
+- Complexity used to signal authority rather than clarify
+- Vague language that lets you avoid commitment
+
+If you'd be frustrated reading what you've written, revise.
+
+## A working diagnostic checklist
+
+When editing a draft, run through:
+
+1. **Subject test.** What is the grammatical subject of each sentence in the paragraph? Is there a topic string? If not, pick an anchor character and rewrite.
+2. **Verb test.** Are the verbs concrete actions, or weak constructions ("is," "has," "makes," "does")? Look for nominalizations to convert back to verbs.
+3. **Voice test.** Each passive sentence: is it passive for a reason? If not, flip to active.
+4. **Stress position test.** What word ends each sentence? Is it the most important word, or a throwaway?
+5. **Cut test.** Read each sentence and ask: which words can I delete without losing meaning? Cut them.
+6. **Length test.** Read aloud. Does the rhythm vary? Do any sentences run on or chop short without purpose?
+7. **Reader test.** If you were the reader, would you understand this on first read?
+
+## When to apply this skill
+
+- Drafting any prose where clarity matters: technical writing, sales copy, internal memos, exec summaries, blog posts, documentation
+- Editing or revising prose that feels dense, abstract, or passive
+- Diagnosing why a paragraph feels off
+- When the user references Williams, *Style: Lessons in Clarity and Grace*, *Style: The Basics of Clarity and Grace*, "old-before-new," "topic string," or "stress position"
+
+This skill complements `ai-writing-tropes` (which lists patterns to avoid). Williams gives the positive principles; tropes gives the negative ones.

+description: Write and file Linear issues (bugs and feature requests) the Agenta way. Use when the user asks to create, file, or draft a Linear or GitHub issue, write a bug report or feature request, or turn a problem into a tracked issue. Covers the title format, reproduction-first structure, when to use a todo list, and the team/project/label/priority/state conventions, plus filing it through the Linear MCP so the linked GitHub issue is auto-created and the PR links back.
+allowed-tools: Read, Edit, Write, Grep, Glob, Bash
+user-invocable: true
+---
+
+# Write Issues
+
+Write issues a teammate can act on without asking you follow-up questions. Lead with what
+the reader needs to reproduce or understand the request, not with your analysis.
+
+Show a draft first and let the user react before you create anything in Linear.
+
+## 1. Title
+
+Prefix the title with the type in parentheses, the same way the repo prefixes PRs.
+
+- `(bug)` for something broken.
+- `(feat)` for a new capability or improvement.
+- Other types as needed: `(chore)`, `(docs)`.
+
+State the symptom or the request in plain words. Keep it short.
+
+- Good: `(bug) Feedback sent via the API can't be filtered in observability`
+- Good: `(feat) Filter evaluation results by metric value`
+- Bad: `(bug) Annotation filter options array empty due to thin refs` (that is the root cause, not the symptom)
+- Bad: `Observability issue` (vague)
+
+## 2. Body — bugs
+
+Do not open with a "Context" heading. Start with the reproduction, in the user's voice:
+when I do this, I expect that, but instead this happens. Or: this code is supposed to do
+X, but it does Y. Keep the words simple.
+
+Then give the concrete information a teammate needs to debug it, when you have it:
+
+- Exact steps to reproduce, numbered.
+- Requests and responses (the call you made and what came back).
+- Errors, console output, or relevant log lines.
+- Screenshots or screen recordings.
+- Where it reproduces (local, preview, Railway, cloud) and the version if known.
+
+That is the whole job: make it reproducible. Include real payloads over descriptions of
+them.
+
+## 3. Do not write the root cause
+
+The issue tracks the problem, not the investigation. Do not add a "root cause" or "why
+this happens" section. That analysis belongs in the PR that fixes it (see the
+`write-pr-description` skill). Keep the issue about observable behavior and the
+information needed to debug it.
+
+If you already know the cause, it still does not go in the issue body. Put it in the PR.
+
+## 4. Body — feature requests
+
+Lead with the problem or the goal from the user's point of view: what they are trying to
+do and why it is hard today. Then describe the behavior they want. Skip implementation
+design unless the user asked for it.
+
+## 5. Todo list
+
+Add a checkbox list only when delivery is split across stacked PRs or has several ordered
+steps. One line per step, written as an outcome.
+
+```
+- [ ] Fix the filter so it reads the evaluator's real feedback metrics.
+- [ ] Fix how the frontend reads the feedback type so the nested schema is understood.
+```
+
+If a single PR closes the whole issue, skip the todo list. Do not pad an issue with
+checkboxes for its own sake.
+
+## 6. Linear fields
+
+File issues on the **Agenta** team (key `AGE`). Pick the fields deliberately.
+
+**Project** (set one):
+- **Bugs** — the default home for bug reports.
+- **Quality of life improvements** — small improvements that do not belong to a feature project.
+- The active feature project when the work is part of one (for example Annotation Queues,
+  Core Loop Improvements, Reliability Availability Scalability & Performance, Documentation,
+  New integrations for observability, DevSecOps & DevEx). List active projects with
+  `mcp__linear-server__list_projects` and match by area.
+
+**Labels** (combine a type label with the relevant area labels):
+- Type: `Bug Report`, `Feature Request`, `Question`, `Chore`, `refactoring`, `tech-debt`.
+  Use `unconfirmed bug` or `reproduction-needed` when you could not reproduce it yet.
+- Area: `frontend`, `Backend`, `SDK`, `API`, `observability`, `Tracing`, `Workflows`,
+  `evaluation`, `human evaluation`, `playground`, `prompt management`, `Services`,
+  `database`, `infrastructure`, `integration`, `security`, `analytics`.
+- UX: `UX`, `ux bug`, `dev experience`.
+- Visibility: `Public` marks an issue mirrored to the public GitHub repo. This is the label
+  the GitHub sync watches, so set it when you want the linked GitHub issue created (see
+  section 7). Use `Core Team` / `Internal Team` for internal-only issues.
+
+**Priority** (`0` None, `1` Urgent, `2` High, `3` Medium, `4` Low):
+- `1` Urgent: data loss, outage, or drop-everything.
+- `2` High: important and should land soon.
+- `3` Medium: the default for a normal bug.
+- `4` Low / `0` None: minor or nice-to-have.
+
+**State** flow: `Todo` → `In Progress` → `In Review` → `In QA` → `Done`. Use `Backlog` for
+later, `Canceled` / `Duplicate` as needed. New issues start in `Todo`; move to `In Progress`
+once work has started.
+
+## 7. Filing it and linking the PR
+
+Create with `mcp__linear-server__save_issue` (no `id` field creates a new issue). Pass
+`team`, `title`, `description` (Markdown, literal newlines), `project`, `labels`,
+`priority`. Link related issues with `relatedTo`, and attach the PR with `links`
+(`[{url, title}]`).
+
+The workspace runs a Linear ↔ GitHub sync that creates a linked GitHub issue when the
+`Public` label is set. After creating the Linear issue, find the auto-created GitHub issue
+(`gh issue list --repo Agenta-AI/agenta --search "<keywords>"`, allow a few seconds for the
+sync), then link the PR to it by adding `Closes #<n>` (or `Refs #<n>` when the PR is only
+part of the issue) to the PR body. The sync then moves the Linear issue as the PR opens and
+merges.
+
+To move the issue yourself, call `save_issue` again with the issue `id` and `state: "In Progress"`.
+
+## 8. Checklist before you create
+
+- Title prefixed with `(bug)` / `(feat)` and states the symptom or request, not the cause.
+- Bug opens with reproduction in plain words, then steps + real requests/responses/logs.
+- No root-cause section.
+- Todo list only if the work is stacked or multi-step.
+- Team, project, labels, priority set. `Public` added if it should sync to GitHub.
+- After creating: GitHub issue found, PR links to it, Linear state set as the user asked.

-# Add Announcement Card
-
-This skill helps you add announcement cards to the Agenta sidebar banner system. Announcement cards appear at the bottom of the sidebar and can be dismissed by users.
-
-## System Overview
-
-The sidebar banner system is located at `web/oss/src/components/SidebarBanners/` and uses:
-- **Priority-based queue**: Only one banner shows at a time
-- **Auto-progression**: When dismissed, the next highest priority banner appears
-- **Persistent dismissal**: Uses localStorage to remember dismissed banners
-- **Jotai atoms**: For reactive state management
-
-## Two Types of Announcements
-
-### 1. Simple Changelog Announcements (Most Common)
-
-For standard product updates, features, and changes, simply add to `changelog.json`:
-
-**File**: `web/oss/src/components/SidebarBanners/data/changelog.json`
-
-**Format**:
-```json
-{
-    "id": "changelog-YYYY-MM-DD-feature-name",
-    "title": "Feature Title (Short)",
-    "description": "Brief description of the feature or change.",
-    "link": "https://agenta.ai/docs/changelog/feature-name"
-}
-```
-
-**ID Convention**: `changelog-` + date (YYYY-MM-DD) + feature slug
-- Example: `changelog-2026-01-09-chat-sessions`
-- Must be unique to prevent conflicts
-
-**Title Guidelines**:
-- Keep under 40 characters
-- Clear and actionable
-- Focus on user benefit
-- Examples: "Chat Sessions in Observability", "PDF Support in Playground"
-
-**Description Guidelines**:
-- One sentence, under 100 characters
-- Describe what users can do, not technical details
-- Examples: "Track multi-turn conversations with session grouping and cost analytics."
-
-**Link Convention**:
-- Always points to `https://agenta.ai/docs/changelog/[feature-slug]`
-- You'll need to create the corresponding changelog documentation page
-
-### 2. Custom Banners (Advanced)
-
-For complex banners with custom UI, interactions, or logic (trial warnings, upgrade prompts, etc.), you need to:
-
-1. Add the banner type to `types.ts`
-2. Add priority to `state/atoms.ts`
-3. Create the banner in `activeBannersAtom` (OSS) or `eeBannersAtom` (EE)
-
-**When to use custom banners**:
-- Non-dismissible banners (e.g., trial expiration)
-- Custom interactions (buttons with onClick handlers)
-- Dynamic content (depends on user state)
-- Conditional display (show only under certain conditions)
-
-## Step-by-Step: Adding a Simple Changelog Announcement
-
-### Step 1: Read the current changelog.json
-```bash
-# View current entries to understand the structure
-cat web/oss/src/components/SidebarBanners/data/changelog.json
-```
-
-### Step 2: Add your entry
-Edit `web/oss/src/components/SidebarBanners/data/changelog.json` and add your new entry to the array:
-
-```json
-[
-    {
-        "id": "changelog-2024-12-16-pdf-support",
-        "title": "PDF Support in Playground",
-        "description": "You can now upload and test PDFs directly in the playground.",
-        "link": "https://agenta.ai/docs/changelog/pdf-support-in-playground"
-    },
-    {
-        "id": "changelog-2026-01-09-your-feature",
-        "title": "Your Feature Title",
-        "description": "Brief description of what users can do.",
-        "link": "https://agenta.ai/docs/changelog/your-feature-slug"
-    }
-]
-```
-
-### Step 3: Verify the format
-- Ensure valid JSON (no trailing commas, proper quotes)
-- Check ID uniqueness
-- Verify link URL matches the documentation page you'll create
-
-### Step 4: Test locally
-The banner will automatically appear in the sidebar on the next page load. To see it:
-1. Clear localStorage: `localStorage.removeItem('agenta:dismissed-banners')`
-2. Refresh the page
-3. Banner should appear at bottom of sidebar
-
-## Banner Priority System
-
-Banners are shown in priority order (lower number = shown first):
-
-```
-Priority 0: star-repo (GitHub star prompt for new users)
-Priority 1: changelog (product updates) ← Most changelog entries
-Priority 2: upgrade (upgrade prompts)
-Priority 3: trial (trial/billing warnings)
-```
-
-Changelog entries automatically get priority 1.
-
-## Common Patterns and Examples
-
-### Example 1: Feature Announcement
-```json
-{
-    "id": "changelog-2026-01-15-batch-evaluation",
-    "title": "Batch Evaluation Available",
-    "description": "Evaluate multiple test sets simultaneously with batch processing.",
-    "link": "https://agenta.ai/docs/changelog/batch-evaluation"
-}
-```
-
-### Example 2: Integration Announcement
-```json
-{
-    "id": "changelog-2026-01-20-langchain-support",
-    "title": "LangChain v0.3 Support",
-    "description": "Full support for LangChain v0.3 with auto-instrumentation.",
-    "link": "https://agenta.ai/docs/changelog/langchain-v03"
-}
-```
-
-### Example 3: Improvement Announcement
-```json
-{
-    "id": "changelog-2026-01-25-faster-traces",
-    "title": "10x Faster Trace Loading",
-    "description": "Observability page now loads traces up to 10x faster.",
-    "link": "https://agenta.ai/docs/changelog/faster-trace-loading"
-}
-```

-- `web/ee/src/components/SidebarBanners/state/atoms.ts` - EE banners (trial, upgrade)
-
-## Best Practices
-
-1. **Timing**: Add announcements when features are fully deployed and documented
-2. **User-focused**: Write from user perspective ("You can now..."), not technical perspective
-3. **Brevity**: Keep title and description short - users skim banners
-4. **Links**: Always link to comprehensive documentation, not just a blog post
-5. **Testing**: Clear localStorage and verify the banner displays correctly
-6. **Uniqueness**: Use date-based IDs to prevent conflicts with past/future announcements
-
-## Troubleshooting
-
-**Banner not appearing?**
-- Check JSON syntax (use a JSON validator)
-- Clear localStorage: `localStorage.removeItem('agenta:dismissed-banners')`
-- Verify you're looking at the correct environment (OSS vs EE)
-- Check browser console for errors
-
-**Banner appearing multiple times?**
-- Ensure ID is unique (not already in the dismissed list)
-- Check for duplicate entries in changelog.json
-
-**Banner styling looks wrong?**
-- The SidebarBanner component handles all styling automatically
-- Don't add custom HTML/styling in description - it's rendered as plain text
-
-## Next Steps After Adding Announcement
-
-After adding the announcement to `changelog.json`, you should:
-
-1. **Create changelog documentation page** at `docs/docs/changelog/[feature-slug].mdx`
-2. **Add screenshots or demo video** to the documentation
-3. **Link to related feature documentation** from the changelog page
-4. **Test the banner** in both OSS and EE environments
-5. **Commit changes** with a descriptive commit message
-
-## Example Workflow
-
-```bash
-# 1. Edit changelog.json
-code web/oss/src/components/SidebarBanners/data/changelog.json
-
-# 2. Create documentation page
-code docs/docs/changelog/your-feature.mdx
-
-# 3. Test locally (if running dev server)
-# Clear localStorage in browser console:
-# localStorage.removeItem('agenta:dismissed-banners')
-
-# 4. Commit
-git add web/oss/src/components/SidebarBanners/data/changelog.json
-git add docs/docs/changelog/your-feature.mdx
-git commit -m "docs: add changelog announcement for [feature name]"
-```

-**Note**: This skill focuses on simple changelog announcements. For custom banners with complex logic, consult the SidebarBanners README or ask for guidance on creating custom banner components.

Subject: [PATCH 123/139] fix(api): declare mount binary responses, regenerate
 the Fern client (#5518)

The three mount routes that return raw bytes declared no response media type, so
FastAPI advertised application/json for them. The generated clients then parsed a
zip or a file body as JSON and corrupted it, which is why the frontend had to call
these routes through raw axios.

Declare the real media types (application/zip for the archive export,
application/octet-stream for the two file downloads). Setting responses= alone is
not enough: FastAPI keeps its default application/json entry unless the route also
declares a response_class with no media type, so both are set. Runtime behavior is
unchanged, since each handler already returns its own Response.

Regenerate the TypeScript client once from the resulting spec, replacing the
exportMountFiles method that was hand-written into the generated directory after
the /files/export rename. The three methods now return core.BinaryResponse with
responseType binary-response, which exposes both .blob() and .stream(). The
regeneration also corrects two pieces of drift the hand-edits had left behind:
GetMountFilesRequest.order becomes a generated enum, and MountFile moves under the
mounts resource.

Refs #5417

Subject: [PATCH 125/139] [fix] Unblock editing schedule and subscription
 triggers (#5552)

* Enhance TimesField component: improve time input handling and add visual cues for removability

* Refactor workflow binding logic: enhance extraction functions and add tests for run version references

* Enhance schedule message handling: support messages payload in completion schema and improve schema readiness checks

* Refactor environment handling: temporarily hide Deployed option in schedule and subscription forms

* Refactor MessageComposer component: remove unused props and improve user message handling

From e31e17350732612fb9ee9fab96f53f7fe322fc07 Mon Sep 17 00:00:00 2001

Subject: [PATCH 126/139] feat: default the session-storage rework flags to on

AGENTA_SESSIONS_RECONSTRUCT, AGENTA_RECORDS_DURABLE, and
NEXT_PUBLIC_SESSIONS_LAST_MESSAGE_ONLY now read as enabled unless set to the
literal "false". Absent and empty both mean on, because the compose files pass
the vars through as ${VAR:-}, which materializes an empty string that overrides
env_file values.

+## Domain nouns, one sentence each
+
+- **Runner**: the Node sidecar (`services/runner/`) that executes one agent turn per
+  HTTP `/run` request.
+- **Sandbox**: the isolated environment a turn runs in; "local" means the runner's own
+  host, "remote" means a Daytona cloud VM.
+- **Turn**: one user-message-to-agent-reply exchange; the runner's unit of work.
+- **Turn boundary**: the moment between two turns, when the runner decides whether to
+  reuse a live environment or build a fresh one.
+- **Session pool**: the runner's in-memory table of live environments parked between
+  turns so the next turn can continue without a rebuild.
+- **Mount**: a directory in the sandbox whose contents live in the object store, so
+  files survive sandbox teardown.
+- **Durable agent volume**: the per-agent mount (`agent-files/`) shared across all
+  sessions of one agent; long-lived by design.
+- **Session scratch**: the per-session working directory mount (`cwd`); re-signed at
+  every turn boundary.
+- **Mount credentials**: the temporary, prefix-scoped S3 key, secret, and session
+  token a mount's geesefs daemon holds; they carry an expiry and cannot be renewed
+  in place.
+- **Installed lease**: the expiry of the credentials a live environment's daemons
+  are actually running on, as opposed to the expiry of credentials signed later and
+  never given to them.
+- **geesefs**: the FUSE filesystem binary that presents an S3 prefix as a local
+  directory; each mount is one geesefs daemon process.
+- **S3**: the object-storage HTTP protocol; Agenta speaks it to whichever store backs
+  the deployment.
+- **SeaweedFS**: the S3-compatible store bundled with self-hosted Agenta.
+- **STS**: the "Security Token Service" protocol for minting temporary, scoped
+  S3 credentials; both SeaweedFS and AWS implement it.
+- **EACCES**: the "Permission denied" error code; geesefs returns it for every file
+  operation once the store answers 403.
+- **ENOTCONN**: the "Transport endpoint is not connected" error code; the kernel
+  returns it when a FUSE daemon has died but its mount point is still registered.
+
+## Related work
+
+- `docs/design/mount-file-viewer/`: the mounts file-listing UI; shares the same sign
+  endpoints, no credential-lifetime logic.
+- Draft PR #5247 and design issue #5215 introduced the durable agent mount this bug
+  hits hardest; its design workspace lives on that PR's branch, not on main.

+# Context: why agent mounts break with "Permission denied"
+
+## What the user experiences
+
+An agent conversation works normally for a while. Then, mid-conversation, every file
+operation under the agent's durable folders starts failing with "Permission denied".
+The agent cannot read or write `agent-files/` or its working directory. The outage
+lasts minutes, then clears on its own when the runner happens to rebuild the
+environment.
+
+On the OSS deployment on 2026-07-25 we counted 16 such denial windows in one day. The
+longest lasted 14 minutes 10 seconds. Writers interrupted mid-operation left stale
+`.git/index.lock` and `.git/config.lock` files behind, which then wedged the
+following turns even after the mount recovered.
+
+The durable per-agent volume is hit hardest because it is long-lived and shared
+across sessions. The per-session scratch directory is re-signed at every turn
+boundary and mostly dodges the window.
+
+## Why it happens
+
+Agent mounts are geesefs FUSE mounts of an object-store prefix. The runner asks the
+API to mint temporary, prefix-scoped store credentials (STS credentials), then starts
+a geesefs daemon with those credentials as static environment variables. Nothing ever
+refreshes them.
+
+Three defects combine into the observed outages. The full evidence is in
+[research.md](research.md); in short:
+
+1. **The credentials expire far earlier than requested.** The API requests a
+   3600-second lifetime, but on SeaweedFS the credentials silently die after 900
+   seconds. SeaweedFS caps every STS session at the expiry of the web-identity token
+   the API authenticates with, and the API mints that token with a fixed 15-minute
+   lifetime.
+2. **The runner's own expiry bookkeeping drifts.** The session pool records when a
+   parked environment's mount credentials expire, and evicts the environment when
+   they do. But on every warm turn it overwrites that record with the expiry of a
+   freshly signed credential that never reaches the running geesefs daemons. After
+   the first warm turn the pool believes the mounts are fresh forever, so an active
+   conversation keeps reusing mounts whose real credentials died long ago.
+3. **Expired credentials are a silent failure mode.** A dead daemon (hard death)
+   returns ENOTCONN, which the runner detects and repairs mid-turn. Expired
+   credentials (soft death) leave the daemon alive and every operation returning
+   EACCES, which nothing detects.
+
+## Goals
+
+- An agent conversation never sees "Permission denied" from an expired mount
+  credential, in either deployment mode: self-hosted OSS with SeaweedFS, or real AWS
+  S3 with AWS STS.
+- The credential lifetime is configurable through an environment variable so QA can
+  shrink it and reproduce the failure quickly.
+- The fix stays small: no new daemons, no new wire fields, no credential-refresh
+  machinery inside the sandbox.
+
+## Non-goals
+
+- In-place credential refresh for a running geesefs daemon. Research.md enumerates
+  the mechanisms; all of them add real machinery, and none is needed once
+  credentials outlive every turn.
+- Cleaning up stale `.git/*.lock` files left by past outages. Those are a downstream
+  symptom; once mounts stop dying mid-write, no new locks are stranded.
+- Per-mount `RoleSessionName` (today every mount signs as the constant
+  `agenta-store`). That is isolation hygiene, orthogonal to expiry, and deferred.
+- Detecting EACCES in the agent's event stream to trigger mid-turn remounts. It is
+  false-positive-prone and redundant once credentials outlive every turn; see the
+  false-positive analysis in research.md.

+# Plan: make mount credentials outlive every turn, and honor their expiry
+
+Four small changes. Three make the credential lifetime real, configurable, and
+trustworthy (API). One makes the runner track the credentials its mounts actually
+hold, and rebuild before they die (runner). No new daemons, no wire changes, no
+refresh machinery inside the sandbox.
+
+## The fix in one paragraph
+
+Today a mount credential requested for 3600 seconds really lives 900 seconds on
+SeaweedFS, because the web-identity token that authenticates the STS call expires
+after 15 minutes and SeaweedFS caps the session at that expiry. And even the true
+expiry is ignored: the session pool overwrites its expiry bookkeeping on every warm
+turn with a freshly signed credential that never reaches the running mounts. The fix
+mints the web-identity token with a lifetime matching the requested duration, makes
+that duration an env-configurable TTL, and refuses to hand out credentials whose
+expiry the store did not report. On the runner side the pooled environment records
+the expiry of the credentials actually installed in its geesefs daemons, and only
+that recorded value ever governs reuse. The pool then does what it was designed to
+do: evict the environment to a cold rebuild, with fresh credentials and fresh mounts,
+before the installed credentials can die under a turn. The required validity window
+is the worst-case turn duration plus a fixed clock-skew allowance, so no turn starts
+on credentials that could expire before it ends.
+
+## Scope against the issue's four fix directions
+
+1. **Detect EACCES like ENOTCONN**: partially already true, remainder deferred. The
+   acquisition probe (`isMounted`) already treats an EACCES `ls` failure as
+   not-mounted and remounts. Extending the mid-turn event watcher to EACCES is
+   deferred: "Permission denied" appears in legitimate agent output constantly, and
+   the trigger becomes unnecessary once credentials outlive every turn
+   (research.md section 5).
+2. **Refresh before expiry**: adopted in its boundary form. Fresh credentials arrive
+   via evict-to-cold at the turn boundary, which is the mechanism the credential
+   epoch was built for. In-place refresh of a running daemon (credential_process or
+   a container-credentials endpoint) is real machinery and is deferred
+   (research.md section 3).
+3. **Raise duration_seconds**: adopted as "make the already-requested 3600 real and
+   configurable". The default stays 3600.
+4. **Per-mount RoleSessionName**: deferred. Isolation hygiene, orthogonal to expiry.
+
+## Change 1: configurable TTL (API)
+
+### `api/oss/src/utils/env.py`
+
+`MountsConfig` is currently empty (env.py:1117):
+
+```python
+class MountsConfig(BaseModel):
+    """Mounts-domain config. Store credentials live in StoreConfig."""
+
+    model_config = ConfigDict(extra="ignore")
+```
+
+Add the TTL, following the existing `int(os.getenv(...) or "...")` pattern
+(compare `catalog_cache_ttl_seconds`, env.py:622). The `or` also absorbs an empty
+string, which is what an unset compose passthrough delivers:
+
+```python
+class MountsConfig(BaseModel):
+    """Mounts-domain config. Store credentials live in StoreConfig."""
+
+    # Lifetime of signed mount credentials. The store backends clamp it to their own
+    # STS bounds (SeaweedFS: effective floor via the web-identity token, hard range
+    # 900-43200 for DurationSeconds; AWS GetFederationToken: 900-129600). QA lowers
+    # it to force fast expiry; only SeaweedFS honors values below 900.
+    credentials_ttl_seconds: int = int(
+        os.getenv("AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS") or "3600"
+    )
+
+    model_config = ConfigDict(extra="ignore")
+```
+
+The config stays on the shared `env` object, per the repo convention that
+application config is read through `env` and never through a bare `os.getenv` at
+the call site.
+
+### `api/oss/src/core/mounts/service.py`
+
+Current (service.py:57-59 and 606-611):
+
+```python
+# Default TTL (seconds) for signed mount credentials. Covers the mount lifetime for a
+# turn; geesefs holds the creds without refresh, so a turn outliving this hits ExpiredToken.
+_CREDENTIALS_TTL_SECONDS = 3600
+...
+    async def sign_mount_credentials(
+        self,
+        *,
+        project_id: UUID,
+        mount_id: UUID,
+        duration_seconds: int = _CREDENTIALS_TTL_SECONDS,
+    ) -> MountCredentials:
+```
+
+Replace the module constant with the env value, resolved at call time (a default
+argument would freeze the import-time value):
+
+```python
+    async def sign_mount_credentials(
+        self,
+        *,
+        project_id: UUID,
+        mount_id: UUID,
+        duration_seconds: Optional[int] = None,
+    ) -> MountCredentials:
+        ...
+        ttl = (
+            duration_seconds
+            if duration_seconds is not None
+            else env.mounts.credentials_ttl_seconds
+        )
+        creds = await self.mounts_store.sign_temp_credentials(
+            bucket=bucket,
+            prefix=prefix,
+            duration_seconds=ttl,
+        )
+```
+
+Add `from oss.src.utils.env import env` to the imports. Delete
+`_CREDENTIALS_TTL_SECONDS` (both sign routes reach this method with the default, so
+no other caller changes).
+
+### `hosting/docker-compose/oss/docker-compose.dev.yml`
+
+The knob has to reach the container that signs. The dev `api` service declares only
+`DOCKER_NETWORK_MODE` under `environment:` and otherwise reads `env_file`
+(docker-compose.dev.yml:119-122), so a shell `export` before `run.sh` never arrives.
+Mirror the store variables' pattern (dev uses map form, the gh file uses list form,
+compare docker-compose.gh.yml:57-62):
+
+```yaml
+        environment:
+            DOCKER_NETWORK_MODE: ${DOCKER_NETWORK_MODE:-bridge}
+            AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS: ${AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS:-}
+```
+
+Add the same line to the `api` service of `docker-compose.gh.yml` (list form) so
+self-hosted operators can set it too.
+
+The QA below also lowers the runner's turn budget, and the `runner` service takes no
+`env_file` at all (docker-compose.dev.yml:380-408). Add the passthrough there as
+well:
+
+```yaml
+            AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS: ${AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS:-}
+```
+
+Both variables are optional. An empty value leaves the code default in place.
+
+## Change 2: make the requested duration real on SeaweedFS (API)
+
+### `api/oss/src/core/store/storage.py`
+
+Current `_sign_web_identity` body (storage.py:232-241):
+
+```python
+        body = urlencode(
+            {
+                "Action": "AssumeRoleWithWebIdentity",
+                "Version": "2011-06-15",
+                "RoleArn": webidentity.role_arn(),
+                "RoleSessionName": webidentity.STORE_SUBJECT,
+                "WebIdentityToken": webidentity.mint_web_identity_token(),
+                "DurationSeconds": str(duration_seconds),
+                "Policy": scope_policy,
+            }
+        )
+```
+
+Two problems: the token's fixed 15-minute lifetime caps the session (research.md
+section 2), and a sub-900 `DurationSeconds` is a hard SeaweedFS request error rather
+than a clamp. Fix both with two private, unit-testable helpers and a token cap:
+
+```python
+# SeaweedFS caps every session at 12h (`maxSessionLength`), so no web-identity token
+# needs to outlive the longest session it could mint.
+_SEAWEEDFS_MAX_SESSION_SECONDS = 43200
+
+
+# SeaweedFS validates DurationSeconds in [900, 43200] when present; the EFFECTIVE
+# lifetime is min(DurationSeconds, web-identity token expiry, maxSessionLength).
+# Minting the token with the requested lifetime makes the request honest, and lets
+# a sub-900 TTL (QA) take effect through the token-expiry cap, which has no floor.
+def _seaweedfs_duration_seconds(duration_seconds: int) -> int:
+    return min(max(duration_seconds, 900), _SEAWEEDFS_MAX_SESSION_SECONDS)
+
+
+# AWS GetFederationToken accepts DurationSeconds in [900, 129600].
+def _federation_duration_seconds(duration_seconds: int) -> int:
+    return min(max(duration_seconds, 900), 129600)
+```
+
+```python
+                "WebIdentityToken": webidentity.mint_web_identity_token(
+                    ttl_seconds=min(duration_seconds, _SEAWEEDFS_MAX_SESSION_SECONDS)
+                ),
+                "DurationSeconds": str(_seaweedfs_duration_seconds(duration_seconds)),
+```
+
+`mint_web_identity_token` already takes a keyword-only `ttl_seconds`
+(webidentity.py:104); no change there. The 15-minute constant
+(`_TOKEN_TTL_SECONDS`, webidentity.py:35) remains the default for any other caller.
+
+In `_sign_federation_token`, replace the bare floor (storage.py:278):
+
+```python
+                "DurationSeconds": str(max(duration_seconds, 900)),
+```
+
+with:
+
+```python
+                "DurationSeconds": str(_federation_duration_seconds(duration_seconds)),
+```
+
+Behavior notes, both modes:
+
+- SeaweedFS, default TTL 3600: token lives 3600s, `DurationSeconds` is 3600, effective
+  lifetime rises from 900s to the intended 3600s. The store-reported `Expiration`
+  stays authoritative and flows to the runner unchanged.
+- SeaweedFS, QA TTL 120: token lives 120s, `DurationSeconds` is 900 (clamped to pass
+  validation), effective lifetime 120s via the token-expiry cap.
+- AWS: the token change is inert (no web-identity path); TTL passes through with
+  AWS's own [900, 129600] bounds. Sub-900 QA values silently become 900, which the
+  QA plan accounts for.
+
+## Change 3: fail closed on a missing expiry (API)
+
+`_parse_sts_credentials` (storage.py:24-52) turns a missing or unparsable
+`Expiration` into `None`, the service passes that through as `expires_at`
+(service.py:639), and the runner reads a missing expiry as "never expires"
+(research.md section 1). One malformed STS response would therefore disable the
+entire safety mechanism silently, for the lifetime of the pooled environment.
+
+Both branches of `sign_temp_credentials` end in this parser and nothing else
+produces mount credentials, so raising here is exactly "the STS paths fail closed"
+(research.md section 1 records the check). Replace the swallow:
+
+```python
+    raw_exp = _text("Expiration")
+    if not raw_exp:
+        raise MountStorageUnavailable("STS response carried no credential expiry.")
+    try:
+        expiration = datetime.fromisoformat(raw_exp.replace("Z", "+00:00"))
+    except ValueError as exc:
+        raise MountStorageUnavailable(
+            "STS response carried an unparsable credential expiry."
+        ) from exc
+```
+
+A refused sign is not a failed turn. The runner already treats a missing mount as a
+degraded, mount-less run (`mount degraded kind=... cause=sign_returned_no_mount`,
+environment-setup.ts:118-122), which is the same outcome as any other sign failure.
+
+## Change 4: track the installed credentials and rebuild before they die (runner)
+
+### The installed lease
+
+The pooled environment must answer one question honestly: "when do the credentials
+that my running geesefs daemons actually hold expire?" Nothing tracks that today.
+The credential epoch is filled from the credentials signed for the current dispatch
+(`computeCredentialEpoch(request, signed?.expiresAt)`, server.ts:382), and those
+credentials never reach the daemons on a warm turn.
+
+Record the answer where it is known: at the moment a mount succeeds. Add to
+`SessionEnvironment` (`services/runner/src/engines/sandbox_agent/runtime-contracts.ts:179`,
+initialized alongside `mountedCwd` in environment-setup.ts:328-338):
+
+```ts
+  /**
+   * Expiry (epoch millis) of the credentials actually installed in each running geesefs
+   * daemon, recorded at successful mount time. Per mount, because a remount replaces one
+   * mount's credentials and must not inherit the other's. The environment's lease is the
+   * minimum over the entries; see `installedMountLease`.
+   */
+  installedMountExpiries: { cwd?: number; agent?: number };
+```
+
+The session cwd and agent mounts go through four call sites, and each stamps its own
+entry from the credentials it just used:
+
+- `mountLocalDurableCwd` (environment.ts:427) and `mountLocalAgentCwd`
+  (environment.ts:448), used both by the initial acquire (environment.ts:596,
+  environment.ts:599) and by the ENOTCONN remount helpers
+  (`reSignAndRemountLocalCwd`, environment.ts:511; `reSignAndRemountLocalAgentMount`,
+  environment.ts:479), which re-sign first and mount second. Stamping inside the
+  mount helpers therefore covers the remount path for free.
+- The two remote mounts, environment.ts:744 (durable cwd) and environment.ts:800
+  (agent mount).
+
+This also covers the acquire-time sign fallback: when the dispatch's up-front sign
+threw, `prepareEnvironmentSetup` signs its own credentials
+(environment-setup.ts:105-114) and the mount helper records whatever was actually
+used, not what the dispatch pre-signed.
+
+The lease itself is a pure helper next to the epoch code
+(`services/runner/src/engines/sandbox_agent/session-identity.ts`):
+
+```ts
+/** The environment's credential lease: the earliest expiry among its installed mounts. */
+export function installedMountLease(expiries: {
+  cwd?: number;
+  agent?: number;
+}): number | undefined {
+  const values = [expiries.cwd, expiries.agent].filter(
+    (v): v is number => v !== undefined,
+  );
+  return values.length ? Math.min(...values) : undefined;
+}
+```
+
+### Park and repark from the lease, never from the dispatch
+
+Both park paths in `services/runner/src/server.ts` read the environment instead of
+the incoming epoch. `parkFreshOrDestroy` (server.ts:460-470) currently parks with
+`credentialEpoch: incomingEpoch`. After a cold acquire the incoming credentials are
+usually the mounted ones, but not always (the acquire may have re-signed), so it
+takes the lease too:
+
+```ts
+      credentialEpoch: {
+        secretsHash: incomingEpoch.secretsHash,
+        mountExpiresAtMs: installedMountLease(env.installedMountExpiries),
+      },
+```
+
+`reparkOrEvict` (server.ts:497-506) is the drift defect. It must carry the installed
+lease forward, and on the approval-resume path it must also keep the live
+environment's secrets hash: that path deliberately ignores the resume request's
+re-minted credentials (server.ts:650-680), so adopting the incoming hash would
+re-label an environment running old secrets as if it ran the new ones.
+
+```ts
+  const reparkOrEvict = async (
+    live: LiveSession<SessionEnvironment>,
+    result: AgentRunResult,
+    opts?: { keepSecretsHash?: boolean },
+  ): Promise<void> => {
+    const env = live.environment;
+    env.clearTurn();
+    const update = {
+      configFingerprint: cfgFp,
+      historyFingerprint: nextHistoryFp(env),
+      credentialEpoch: {
+        // The resume path never re-baked secrets into this environment, so the parked
+        // hash still describes what it runs.
+        secretsHash: opts?.keepSecretsHash
+          ? live.credentialEpoch.secretsHash
+          : incomingEpoch.secretsHash,
+        // The environment runs on the credentials installed in its daemons, not on the
+        // ones this dispatch signed to compute the pool key.
+        mountExpiresAtMs: installedMountLease(env.installedMountExpiries),
+      },
+    };
+```
+
+The continuation path keeps calling `reparkOrEvict(live, result)` (server.ts:638);
+the approval-resume path calls `reparkOrEvict(live, result, { keepSecretsHash: true })`
+(server.ts:749).
+
+### Lease sufficiency is a separate question from identity
+
+A turn dispatched one minute before expiry would still die mid-turn, so reuse needs
+credentials valid through the end of the turn, not merely valid now. That is a
+different question from "is this the same environment the request expects", and it
+gets its own check rather than a future timestamp threaded through the identity
+comparison. `credentialEpochMismatch` (session-identity.ts:369) keeps its current
+meaning: secrets rotated, or credentials already dead. Next to it:
+
+```ts
+/**
+ * A fixed allowance for clock differences between the API, the store, and the runner, plus
+ * the seconds a cold rebuild spends mounting before the turn starts. Not operator-tunable:
+ * it protects an invariant, and a third time knob would only invite mis-setting it.
+ */
+export const MOUNT_LEASE_SKEW_MS = 60_000;
+
+/**
+ * Whether the parked mount credentials would expire before `requiredValidThroughMs`, i.e. the
+ * lease cannot cover a full worst-case turn. Distinct from `mountCredentialsExpired`, which
+ * asks only whether the lease is already dead.
+ */
+export function mountCredentialsExpireBy(
+  epoch: CredentialEpoch,
+  requiredValidThroughMs: number,
+): boolean {
+  return (
+    epoch.mountExpiresAtMs !== undefined &&
+    epoch.mountExpiresAtMs <= requiredValidThroughMs
+  );
+}
+```
+
+The dispatch resolves the run limits once and derives the window (server.ts, next to
+`incomingEpoch` at server.ts:382). `resolveRunLimits` is imported directly from
+`./engines/sandbox_agent/run-limits.ts`, as server.ts already imports other engine
+internals:
+
+```ts
+  // Resolved once per dispatch: the longest a turn started now could still be running.
+  const requiredValidThroughMs =
+    Date.now() + resolveRunLimits().totalMs + MOUNT_LEASE_SKEW_MS;
+```
+
+The idle-reuse branch (server.ts:569-577) gains the lease check after the identity
+check, with its own reason string, because credentials that are still valid at
+eviction time are expiring, not expired:
+
+```ts
+    const credMismatch = credentialEpochMismatch(
+      existing.credentialEpoch,
+      incomingEpoch,
+    );
+    let mismatch: string | undefined;
+    if (cfgFp !== existing.configFingerprint) mismatch = "config";
+    else if (priorFp !== existing.historyFingerprint) mismatch = "history";
+    else if (credMismatch) mismatch = credMismatch;
+    else if (
+      mountCredentialsExpireBy(existing.credentialEpoch, requiredValidThroughMs)
+    )
+      mismatch = "credentials-expiring";
+    else if (!tailIsFreshUserMessage(request)) mismatch = "tail";
+```
+
+The approval-resume branch (server.ts:678) keeps its hard-expiry check and gains the
+same lease check:
+
+```ts
+    } else if (mountCredentialsExpired(existing.credentialEpoch)) {
+      mismatch = "credentials-expired";
+    } else if (
+      mountCredentialsExpireBy(existing.credentialEpoch, requiredValidThroughMs)
+    ) {
+      mismatch = "credentials-expiring";
+    }
+```
+
+The skew allowance applies at both moments that matter. At dispatch it keeps a turn
+from starting on a lease it could outlive. After a cold rebuild it is respected by
+construction, because the lease is recorded after the mount succeeds, so the mount
+and provisioning time is already spent when the clock starts.
+
+### A short lease warns, it never fails the turn
+
+When the configured TTL is smaller than the turn budget plus skew, even a freshly
+mounted environment cannot satisfy `requiredValidThroughMs`, and every dispatch
+evicts to cold. That state is correct (fresh credentials every turn, no EACCES) and
+it is exactly what a QA-lowered TTL asks for, so it must not be an error. A hard
+failure would turn one mis-set number into a full outage, while proceeding is no
+worse than today's behavior. So the runner logs once per acquisition, naming both
+knobs and both values, and runs the turn:
+
+```ts
+    // Once per acquisition: the lease cannot cover a worst-case turn even when brand new.
+    klog(
+      `lease-short key=${key} leaseMs=${leaseMs} required=${requiredMs} ` +
+        `(AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS on the API vs ` +
+        `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS=${totalMs}ms + skew ${MOUNT_LEASE_SKEW_MS}ms); ` +
+        `running anyway, every dispatch will rebuild cold`,
+    );
+```
+
+### What this yields per failure mode
+
+- Active conversation crossing expiry (the observed outages): the first dispatch
+  inside the required-validity window logs `mismatch (credentials-expiring)`,
+  evicts, rebuilds cold with fresh mounts. Sub-second blip instead of a
+  multi-minute window.
+- Turn longer than the remaining lease: cannot happen while the TTL exceeds the turn
+  budget plus skew, because the lease check already forced a cold rebuild.
+- Hard daemon death: unchanged, the existing ENOTCONN probe and watcher handle it,
+  and a successful remount now updates the lease it re-signed.
+- Sessionless runs: mount at acquire with fresh full-TTL credentials, turn bounded
+  by the 45-minute deadline. Covered.
+- Daytona remote: identical logic; the lease and the window are backend-neutral.
+
+### Rebuild rate, honestly
+
+With the default TTL of 3600s, the default turn budget of 2700s (45 minutes), and
+60s of skew, the warm-reuse window is about 840 seconds. An active conversation
+therefore rebuilds cold roughly every 14 minutes, not once an hour. That is the
+price of guaranteeing that no turn starts on credentials it could outlive, and it is
+no more churn than the 900-second lifetime produces today. A cold rebuild is
+cheap locally. On Daytona it is not: a credential eviction tears the environment
+down with reason `compatibility-mismatch`, which maps to `delete`
+(`teardownDisposition`, teardown.ts:23-37), so the remote sandbox is destroyed and
+the next turn pays a full create.
+
+The default stays 3600. Measure the rebuild rate in production first. If the churn
+hurts, the answer is in-place refresh through a container-credentials endpoint
+(research.md section 3, mechanism 4), not a 12-hour TTL: a longer TTL only moves the
+boundary, while every hour of extra lifetime is an hour a leaked credential stays
+usable.
+
+## Tests
+
+### API unit tests (pytest)
+
+Extend `api/oss/tests/pytest/unit/test_mounts_injection.py`, which already has the
+`_CapturingPost` seam that stands in for `aiohttp.ClientSession` and captures the one
+STS POST (test_mounts_injection.py:312-357):
+
+- SeaweedFS request, TTL 3600: captured body has `DurationSeconds=3600`, and the
+  captured `WebIdentityToken` decodes (PyJWT, `verify_signature: False`) to
+  `exp - iat == 3600`.
+- SeaweedFS request, TTL 120: body has `DurationSeconds=900` (the floor), token
+  `exp - iat == 120` (the sub-900 lever).
+- SeaweedFS request, TTL 90000: body has `DurationSeconds=43200` and the token is
+  capped at 43200 as well.
+- AWS `GetFederationToken`: TTL 60 becomes 900, 3600 passes through, 200000 becomes
+  129600.
+- Fail closed: an STS XML body with no `Expiration`, and one with
+  `<Expiration>not-a-date</Expiration>`, each raise `MountStorageUnavailable` from
+  `sign_temp_credentials`. The existing fixture XML carries a valid `Expiration`
+  (test_mounts_injection.py:348-357), so the current cases keep passing.
+- `MountsConfig.credentials_ttl_seconds`: default 3600; env override parses; an
+  empty string falls back to 3600 (construct `MountsConfig` under
+  `monkeypatch.setenv`).
+
+Run: `cd api && uv run --no-sync pytest oss/tests/pytest/unit/test_mounts_injection.py`.
+
+### Runner unit tests (vitest)
+
+Extend `services/runner/tests/unit/session-keepalive-dispatch.test.ts` (fake
+`KeepaliveEngine` plus real pool, the existing seam). No wall-clock waits: fake the
+date only, so the pool's own timers and the test's `flush()` keep working.
+
+```ts
+vi.useFakeTimers({ toFake: ["Date"] });
+vi.setSystemTime(T0);
+// ... vi.setSystemTime(T0 + delta) between dispatches
+vi.useRealTimers();
+```
+
+The fake engine gains a per-call sequence of signed expiries, and its
+`acquireEnvironment` stamps `installedMountExpiries` on the fake environment from the
+credentials it "mounted", exactly as the real mount helpers do. Cases:
+
+- **Repark keeps the installed lease**: turn 1 acquires with an expiry at T0+10min;
+  turn 2 runs warm while the dispatch signs a far-future expiry; advancing the clock
+  so the installed lease falls inside the required-validity window forces turn 3
+  cold (acquire called again). Without the fix turn 3 continues warm.
+- **Approval resume preserves both**: an `awaiting_approval` repark keeps the live
+  environment's secrets hash (a resume request carrying different secrets does not
+  relabel the parked environment) and its installed lease.
+- **The lease is the minimum**: an environment whose session-cwd mount expires
+  before its agent mount is evicted on the earlier of the two.
+- **Boundary cases**: a lease exactly at `now + totalMs + MOUNT_LEASE_SKEW_MS`
+  evicts (`credentials-expiring`); one millisecond beyond it continues warm; one
+  already in the past still reports `credentials-expired`. Drive `totalMs` through
+  `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS`, restored after each case.
+
+Run: `cd services/runner && pnpm test && pnpm run typecheck`.
+
+## Live QA (local OSS stack, SeaweedFS)
+
+Sequenced so the broken behavior is demonstrated with the same knobs that ship. The
+numbers are chosen so a whole turn plus the 60-second skew still fits inside one
+lease, which keeps the reproduction from depending on turn timing: TTL 120 seconds,
+runner turn budget 30 seconds, required validity 90 seconds.
+
+1. **Deploy the API half only** (TTL env, token fix, fail-closed parsing), runner
+   unpatched. Add `AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS=120` to
+   `hosting/docker-compose/oss/.env.oss.dev` (or export it, now that the compose
+   passthrough from Change 1 exists), then
+   `load-env hosting/docker-compose/oss/.env.oss.dev` and
+   `bash ./hosting/docker-compose/run.sh --oss --dev`. The dev API hot-reloads code
+   but not env, so use `--recreate api` to pick the variable up.
+2. **Reproduce the window**: start an agent session that touches its durable mount
+   every turn (prompt the agent to run `date >> agent-files/log.txt && cat
+   agent-files/log.txt`). Send turns every ~20 seconds. Within two turns past the
+   120-second mark the agent reports "Permission denied" on `agent-files/`, while
+   runner logs show `hit-continue` (warm reuse of the dead mount). This is the bug,
+   on demand.
+3. **Deploy the runner half**, same TTL, plus
+   `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS=30000`. A lease now has to stay valid for 90
+   seconds (30s budget plus 60s skew), so turns dispatched in the first ~30 seconds
+   after a mount continue warm, and the next one logs
+   `mismatch (credentials-expiring) ... evict + cold`. That turn succeeds, and the
+   file written before the rebuild is still there (durability across the cold
+   remount). No denial window at any cadence.
+4. **Confirm the short-lease warning**: drop the TTL to 60 with the same 30-second
+   budget. Every dispatch rebuilds cold, each acquisition logs `lease-short` naming
+   both knobs, and turns still succeed.
+5. **Restore defaults** (unset both, recreate), then rerun the original long
+   scenario: an active conversation with periodic file writes for more than 20
+   minutes shows no denial window (previously it broke at 15 minutes) and rebuilds
+   cold about every 14 minutes.
+6. **AWS mode**: not exercised in this QA. The AWS path is covered by the clamp unit
+   tests and the analysis in research.md section 4; on real AWS the TTL floor is 900,
+   so the fast reproduction is SeaweedFS-only. Optional follow-up: one staging pass
+   with TTL 900 and a conversation longer than 15 minutes.
+
+Per the QA-recording rule, capture step 2 and step 3 as an MP4 for the PR.
+
+## Rollout notes
+
+- API and runner halves are independently safe. API-only: the effective SeaweedFS
+  lifetime rises from 900s to 3600s, windows become rarer but the drift remains.
+  Runner-only: the real lifetime stays 900s, which is below the turn budget plus
+  skew, so every dispatch rebuilds cold and logs `lease-short`. That is correct and
+  denial-free, just churny. Ship both together.
+- No wire change: `expires_at` already flows.
+- Operators: keep `AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS` above
+  `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS` (as seconds) plus 60 seconds of skew, or
+  every dispatch rebuilds cold and the runner says so in its log. SeaweedFS also
+  caps the TTL at its configured `maxSessionLength` (12h in our compose file);
+  values above 43200 are clamped in code before the request.
+- Real AWS deployments must sign with long-term IAM user credentials.
+  `GetFederationToken` rejects an assumed-role session, and root credentials cap the
+  duration at 3600 seconds regardless of the TTL (research.md section 4).
+- EE and production compose files need the same TTL passthrough as the OSS files
+  before the knob is usable there.
+- The web-identity JWT now lives as long as the TTL, capped at 12h (research.md
+  section 4 covers the widened-replay-window tradeoff; the token never leaves the
+  API-to-store hop).
+
+## Open questions for review
+
+1. **Remote transcript mounts**: on Daytona, the harness session and transcript
+   directories are separate mounts, each signed at acquire with its own credentials
+   (`mountHarnessSessionDirs`, environment.ts:766). They are signed seconds apart
+   from the durable cwd and agent mounts at the same TTL, so the lease already
+   bounds them within noise. Should they still get their own lease entries, or is
+   the current minimum-of-two the right stopping point?

+(the bundled store, see `hosting/docker-compose/oss/docker-compose.dev.yml:521`).
+
+## 1. The credential path, end to end
+
+### Signing (API side)
+
+- The runner calls `POST /sessions/mounts/sign` for the session scratch mount
+  (`api/oss/src/apis/fastapi/sessions/router.py:920`) and
+  `POST /mounts/agents/sign` for the durable agent mount
+  (`api/oss/src/apis/fastapi/mounts/router.py:151`). Both land in
+  `MountsService.sign_mount_credentials`
+  (`api/oss/src/core/mounts/service.py:606`), which requests a lifetime of
+  `_CREDENTIALS_TTL_SECONDS = 3600` (`service.py:59`).
+- `ObjectStore.sign_temp_credentials` (`api/oss/src/core/store/storage.py:188`)
+  builds one inline session policy scoped to the mount prefix, then branches on the
+  backend:
+  - **SeaweedFS** (selected when `AGENTA_STORE_SIGNING_KEY` is set,
+    `storage.py:93-97`): `_sign_web_identity` (`storage.py:226`) posts an
+    unauthenticated `AssumeRoleWithWebIdentity` carrying a self-minted RS256 JWT
+    (`webidentity.mint_web_identity_token`, `storage.py:238`) and
+    `DurationSeconds=str(duration_seconds)` (`storage.py:239`).
+  - **Remote S3-compatible store (AWS, MinIO)**: `_sign_federation_token`
+    (`storage.py:258`) posts a SigV4-signed `GetFederationToken` with
+    `DurationSeconds=str(max(duration_seconds, 900))` (`storage.py:278`).
+- The web-identity JWT is minted with a fixed 15-minute lifetime:
+  `_TOKEN_TTL_SECONDS = 15 * 60` (`api/oss/src/core/store/webidentity.py:35`),
+  used by `mint_web_identity_token` (`webidentity.py:104`).
+- The STS XML response is parsed into a miniopy `Credentials` including
+  `Expiration` (`storage.py:24-52`), and the service returns
+  `expires_at=getattr(creds, "_expiration", None)`
+  (`service.py:639`). miniopy-async stores the constructor's `expiration` as
+  `_expiration` (site-packages `miniopy_async/credentials/credentials.py:54`), so
+  the true store-side expiry reaches the wire as an ISO datetime
+  (`api/oss/src/core/mounts/dtos.py:132`).
+- **The expiry is optional the whole way down.** `_parse_sts_credentials` turns a
+  missing or unparsable `Expiration` into `None` (`storage.py:39-45`), the DTO field
+  is `Optional[datetime]` (`dtos.py:132`), and the runner reads a missing expiry as
+  "never expires": `computeCredentialEpoch` leaves `mountExpiresAtMs` undefined
+  (`session-identity.ts:333-347`) and both expiry checks return false on undefined
+  (`session-identity.ts:356-367`). One malformed STS response therefore disables the
+  whole reuse bound silently, for as long as that environment stays parked.
+  Fail-closing is safe on both backends: `sign_temp_credentials` is the only producer
+  of mount credentials, and both of its branches are STS calls that end in this one
+  parser (`storage.py:222-224`). No static or master-key path hands credentials to a
+  mount; the master keys are used only to sign the `GetFederationToken` request and
+  for the API's own file operations (`_client`, `storage.py:107`). So there is no
+  legitimate no-expiry case to preserve.
+
+### Mounting (runner side)
+
+- `signSessionMountCredentials` (`services/runner/src/engines/sandbox_agent/mount.ts:68`)
+  and `signAgentMountCredentials`
+  (`services/runner/src/engines/sandbox_agent/agent-mount.ts:39`) fetch the sign
+  endpoints and surface `expiresAt` on `MountCredentials` (`mount.ts:36`).
+- Locally, `mountStorage` (`mount.ts:299`) spawns
+  `geesefs --no-detect --fsync-on-close -f -o allow_other <bucket>:<prefix> <cwd>`
+  (`geesefsArgs`, `mount.ts:214`) with the credentials as static child environment
+  variables `AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` / `AWS_SESSION_TOKEN`
+  (`credEnv`, `mount.ts:237`). Remotely (Daytona), `mountStorageRemote`
+  (`mount.ts:641`) runs the same argv inside the sandbox.
+- Mounts are established once, during environment acquisition:
+  `environment.ts:596` and `environment.ts:599` (local session cwd + agent mount,
+  before the harness daemon spawns), `environment.ts:744` and `environment.ts:800`
+  (remote).
+- **Where the installed credentials come from.** The local mounts go through two
+  helpers, `mountLocalDurableCwd` (`environment.ts:427`) and `mountLocalAgentCwd`
+  (`environment.ts:448`), which read `environment.mountCreds` /
+  `environment.agentMountCreds` and pass them to geesefs. Those two fields are the
+  only description of what a daemon holds, and they are set in three places: the
+  acquire-time sign in `prepareEnvironmentSetup` (`environment-setup.ts:105-114`,
+  which signs for itself when the dispatch's up-front sign threw and passed
+  `undefined`), the agent-mount sign right after it (`environment-setup.ts:127-134`),
+  and the ENOTCONN re-sign helpers, which overwrite one field and remount through the
+  same helper (`environment.ts:479` and `environment.ts:511`). On Daytona the two
+  remote mounts read the same fields. Anything that records "what is installed" has
+  to hook these mount call sites, not the sign call sites: a sign whose credentials
+  never reach a daemon changes nothing about the running mount.
+- Daytona sandboxes additionally mount the harness session and transcript directories
+  (`mountHarnessSessionDirs`, `environment.ts:766`), each signing its own credentials
+  per directory (`mount.ts:735`) at the same TTL, seconds apart from the other two.
+
+### Liveness probing and hard-death recovery (already present)
+
+- `isMounted` (`mount.ts:255`) runs `mountpoint -q` then a real `ls -A`. Any `ls`
+  failure, ENOTCONN or otherwise, counts as not-mounted, so `mountStorage`
+  force-detaches and remounts. This probe runs only inside `mountStorage`, i.e.
+  only during acquisition.
+- Mid-turn, `remountLocalCwdAfterRuntimeEnotconn` (`environment.ts:540`) watches
+  every ACP event for ENOTCONN markers
+  (`containsTransportEndpointDisconnected`,
+  `services/runner/src/engines/sandbox_agent/runtime-policy.ts:136`) and re-signs +
+  remounts both local mounts, at most once per environment
+  (`LOCAL_DURABLE_CWD_ENOTCONN_REMOUNT_LIMIT = 1`, `environment.ts:141`).
+- Nothing watches for EACCES. Expired credentials leave the daemon alive, so
+  neither `mountpoint -q` nor the ENOTCONN watcher fires.
+
+### Turn boundaries and the session pool (runner side)
+
+- Every dispatch with a session id signs fresh session-cwd credentials up front
+  (`engine.resolveKeepaliveMount`, called at
+  `services/runner/src/server.ts:363`; implementation
+  `environment.ts:225`). The result feeds two things: the pool key, and the
+  incoming credential epoch
+  (`computeCredentialEpoch(request, signed?.expiresAt)`, `server.ts:382`).
+- The credential epoch
+  (`services/runner/src/engines/sandbox_agent/session-identity.ts:326`) exists to
+  bound how long a parked environment may reuse its baked credentials:
+  `mountExpiresAtMs` holds the mount credential expiry, and
+  `credentialEpochMismatch` (`session-identity.ts:369`) evicts a parked
+  environment to a cold rebuild once that expiry passes.
+- **The drift defect**: after a warm turn, `reparkOrEvict` re-parks the same
+  environment with `credentialEpoch: incomingEpoch` (`server.ts:506`). The
+  incoming epoch carries the expiry of the credentials signed for THIS dispatch,
+  but those credentials were only used to compute the pool key; the running
+  geesefs daemons still hold the credentials from acquisition, and the warm path
+  never remounts (`hit-continue` goes straight to `runTurn`, `server.ts:587-600`).
+  So every warm turn pushes `mountExpiresAtMs` forward while the real mount
+  credentials age in place. An active conversation therefore never trips
+  `credentials-expired` and keeps running turns against a mount whose credentials
+  died at acquisition-time + TTL. A fresh park after a cold acquire
+  (`parkFreshOrDestroy`, `server.ts:470`) is usually right, because the incoming
+  credentials are normally the ones just mounted. It is not guaranteed: when the
+  up-front sign threw, the acquire signed its own credentials
+  (`environment-setup.ts:105-114`) and the incoming epoch describes a sign that never
+  reached a daemon.
+- Idle reaping is aggressive (`DEFAULT_TTL_MS = 60_000` local,
+  `DEFAULT_DAYTONA_TTL_MS = 120_000`, `session-identity.ts:33,40`), so quiet
+  sessions get torn down and remounted fresh anyway. Only conversations with
+  turns arriving faster than the idle TTL keep one environment alive long enough
+  to cross the credential expiry. That matches the field observation: active
+  sessions on the durable agent volume were hit hardest.
+- Evicting for a credential reason is not free on Daytona. The dispatch evicts with
+  teardown reason `compatibility-mismatch` (`server.ts:583`, `server.ts:689`), and
+  `teardownDisposition` maps that to `delete`, not `stop`
+  (`services/runner/src/engines/sandbox_agent/teardown.ts:23-37`). The remote sandbox
+  is destroyed and the next turn pays a full create; only clean, idle, and capacity
+  teardowns park the sandbox in a stopped state.
+- Turn length is bounded: `DEFAULT_TOTAL_DEADLINE_MS = 45 * 60_000`
+  (`services/runner/src/engines/sandbox_agent/run-limits.ts:37`), overridable via
+  `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS`.
+
+## 2. What actually expires, and when: the 15-minute cap
+
+The issue reports denial starting about 15 minutes after mount, yet the service
+requests 3600 seconds. Both numbers are real. SeaweedFS 4.37 caps every STS session
+at the expiry of the web-identity token presented to it
+(`weed/iam/sts/sts_service.go`, `calculateSessionDuration`):
+
+```go
+// If the source token has an expiration, cap the session duration to not exceed it
+if tokenExpiration != nil && !tokenExpiration.IsZero() {
+    timeUntilTokenExpiry := time.Until(*tokenExpiration)
+    ...
+    } else if timeUntilTokenExpiry < duration {
+        duration = timeUntilTokenExpiry
+    }
+}
+```
+
+Our JWT lives 15 minutes (`webidentity.py:35`), so every SeaweedFS mount credential
+dies after at most 900 seconds regardless of `DurationSeconds=3600`. The STS
+response's `Expiration` reflects the capped value (the response credentials are
+generated from the capped `expiresAt`), so the runner's epoch data was always
+truthful; only the repark drift (section 1) discarded it.
+
+Timeline of one observed outage, with the pieces above:
+
+1. Turn 1 (cold): sign, mount, park. Real expiry: T+15 min. Epoch records T+15 min.
+2. Turns 2..N (warm, active conversation): each dispatch signs fresh credentials,
+   overwrites the epoch with a new T'+15 min, never remounts.
+3. T+15 min: the store starts answering 403 to the daemons; geesefs maps 403 to
+   EACCES (`core/backend_s3.go`, `case 403: err = syscall.EACCES`). Every file
+   operation in the mount fails "Permission denied". `mountpoint -q` still passes.
+4. The outage persists until a turn fails hard enough to evict (history mismatch,
+   thrown continuation, idle reap), up to the observed 14 minutes.
+
+## 3. Mechanism space: getting fresh credentials into geesefs v0.43.0
+
+geesefs v0.43.0 vendors a fork of aws-sdk-go v1 under `s3ext/`. Credential
+resolution (`core/cfg/conf_s3.go:107-181`): explicit `AccessKey`/`SecretKey` flags
+become static credentials; otherwise the SDK session default chain runs with
+`SharedConfigState: session.SharedConfigEnable` (`conf_s3.go:157-161`), which
+resolves, in order: static env vars, shared config/credentials files (including
+`credential_process`), then remote providers (container endpoint, IMDS). Every
+option, verified against the pinned source:
+
+| # | Mechanism | Supported in v0.43.0? | Refreshes after expiry? | Verdict |
+| --- | --- | --- | --- | --- |
+| 1 | Static `AWS_*` env vars (current approach) | Yes | No. Static provider never expires. | Status quo; credentials die at TTL. |
+| 2 | Shared credentials file the runner rewrites (`~/.aws/credentials`, `--shared-config`) | Yes | **No.** `SharedCredentialsProvider.IsExpired()` returns `!p.retrieved` (`s3ext/aws/credentials/shared_credentials_provider.go:71-73`): the file is read once and never re-read. geesefs never calls `Expire()` on 403 either (`core/backend_s3.go` maps 403 to EACCES and treats it as non-retryable). | Ruled out. The "just rewrite a file" hope does not hold for this SDK generation. |
+| 3 | `credential_process` in a shared config profile | Yes (`s3ext/aws/session/credentials.go:107-109` wires `processcreds`) | **Yes.** `processcreds` honors the process output's `Expiration` and re-runs the process when it passes (`s3ext/aws/credentials/processcreds/provider.go:109-132`). | Viable locally: the runner would install a config file plus a helper that re-calls the sign endpoint. Requires dropping the `AWS_*` env (env wins the chain) and giving the helper long-lived API auth. On Daytona the helper would put API credentials inside the agent-reachable sandbox. Real machinery; deferred. |
+| 4 | Container credentials endpoint (`AWS_CONTAINER_CREDENTIALS_FULL_URI`) | Yes (`s3ext/aws/defaults/defaults.go:117-127`, `endpointcreds`) | **Yes.** `endpointcreds` sets expiry from the JSON response and re-fetches (`s3ext/aws/credentials/endpointcreds/provider.go:107-132`). | The strongest in-place-refresh option if ever needed: the runner serves a loopback JSON endpoint, geesefs polls it. Locally clean; remotely it needs a tunnel plus auth on the endpoint. Deferred for the same simplicity reason as #3. |
+| 5 | IMDS emulation (`169.254.169.254`, `ec2rolecreds`) | Yes (default chain) | Yes | Requires owning the link-local address inside every container/sandbox. Impractical; rejected. |
+| 6 | geesefs `--iam` / `--iam-url` built-in refresh | Yes, and it does refresh on a timer (`core/backend_s3.go:119-208`) | Yes, but | It replaces SigV4 signing entirely with a Yandex-style bearer header (`setIAMSigner` clears the Sign handler list and sets `X-YaCloud-SubjectToken`, `backend_s3.go:210-219`). SeaweedFS and AWS require SigV4. Rejected. |
+| 7 | geesefs `--role-arn` (SDK `stscreds.AssumeRoleProvider`, auto-refreshing) | Yes (`conf_s3.go:169-177`) | Yes | Needs long-lived base credentials on the mount host to assume with. That breaks the design invariant that the runner never holds bucket-wide keys (`mount.ts:5-7`). Rejected. |
+| 8 | Remount with fresh credentials at turn boundaries (evict the pooled environment to cold) | N/A (runner-side) | Yes | Already the designed behavior of the credential epoch; it is broken because the epoch tracks per-dispatch signing instead of what the daemons were given. Between turns nothing holds the mount, so a rebuild is safe. **Chosen.** |
+
+Conclusion: within geesefs v0.43.0 there is no zero-machinery way to refresh a
+running daemon's SigV4 credentials. The two real refresh mechanisms (#3, #4) both
+add a credential-serving surface, and the remote variant weakens the security
+boundary. Boundary remounting (#8) already exists as designed behavior; the fix
+repairs it by recording what each mount was actually given, and sizes the TTL so no
+turn can outlive its credentials.
+
+## 4. Self-hosted SeaweedFS versus real AWS S3
+
+The fix must be safe in both deployment modes. They differ in every relevant
+detail, so each is analyzed separately.
+
+### Self-hosted OSS: SeaweedFS 4.37 with its built-in STS
+
+- **STS verb**: `AssumeRoleWithWebIdentity`, authenticated by our RS256 JWT
+  validated against the API's JWKS
+  (`hosting/docker-compose/oss/docker-compose.dev.yml:540` configures the OIDC
+  provider; `webidentity.py` mints the token).
+- **DurationSeconds floor and ceiling**: when the request carries
+  `DurationSeconds`, SeaweedFS validates `900 <= v <= 43200`
+  (`weed/iam/sts/sts_service.go:839-841`, "DurationSeconds must be between 900 and
+  43200 seconds"). Values outside the range are a hard request error, not a clamp.
+- **Effective lifetime**: `min(DurationSeconds, web-identity token expiry,
+  maxSessionLength)` (`calculateSessionDuration`, `sts_service.go:1021-1054`).
+  `maxSessionLength` is 12h in our compose config (`docker-compose.dev.yml:540`).
+  The web-identity-token cap has **no 900-second floor**: a JWT that expires in 60
+  seconds yields 60-second credentials even when `DurationSeconds=900`. This is
+  the QA lever for sub-900 lifetimes.
+- **Expiry enforcement**: the session token is a stateless JWT whose `exp` is
+  validated on every S3 request (`weed/iam/sts/session_claims.go:137`). An expired
+  token gets 403; geesefs maps 403 to EACCES. Matches the field observation.
+- **Fix safety**: minting the web-identity JWT with a lifetime matching the
+  requested duration removes the silent cap, so the requested 3600s becomes real.
+  The JWT never leaves the API-to-store network hop; lengthening it from 15
+  minutes to the configured TTL widens the replay window of that internal token
+  accordingly, which is why the token lifetime is also capped at 43200 seconds: no
+  bearer token should outlive the longest session it can mint. The token only
+  permits assuming the store role, and prefix
+  isolation continues to rest on the inline session policy
+  (`storage.py:209-212`), unchanged by this fix. Note the pre-existing sharp
+  edge, also unchanged: anyone holding that JWT could assume the role without a
+  session policy and reach the whole bucket, which is why it must stay inside the
+  API trust boundary.
+
+### Real AWS S3 with real AWS STS
+
+- **STS verb**: `GetFederationToken`, SigV4-signed with the deployment's IAM user
+  keys against `AGENTA_STORE_STS_ENDPOINT_URL` (`storage.py:258-281`,
+  `api/oss/src/utils/env.py:1092`). No web-identity token exists on this path, so
+  the JWT change is inert here.
+- **Who may call it**: AWS accepts `GetFederationToken` only from the long-term
+  access keys of an IAM user. An assumed-role session or any other temporary
+  credential is rejected outright, and root-account keys, while accepted, cap every
+  federation token at 3600 seconds no matter what `DurationSeconds` asks for. An AWS
+  deployment must therefore provision a dedicated IAM user for the store and put its
+  keys in `AGENTA_STORE_ACCESS_KEY` / `AGENTA_STORE_SECRET_KEY`. The [900, 129600]
+  range below assumes that; under root keys the effective TTL ceiling is one hour.
+- **DurationSeconds floor and ceiling**: AWS enforces 900 minimum and 129600 (36h)
+  maximum for `GetFederationToken`. The code already clamps the floor
+  (`max(duration_seconds, 900)`, `storage.py:278`). QA cannot get sub-900
+  credentials from real AWS; the low-TTL reproduction is SeaweedFS-only.
+- **Effective lifetime**: exactly `DurationSeconds`; the response `Expiration` is
+  authoritative and flows to the runner the same way.
+- **Expiry enforcement**: S3 rejects expired session tokens with 403
+  `ExpiredToken`; geesefs maps it to EACCES identically.
+- **Fix safety**: the API change reduces to "the TTL constant becomes an env var,
+  clamped into [900, 129600]", plus refusing a response with no parsable
+  `Expiration`, which AWS always sends. The runner changes (record the installed
+  lease, require it to cover a full turn) key off the `expires_at` the STS response
+  reported, not off any backend assumption, so they behave identically against AWS.
+  No AWS-side configuration changes beyond the IAM user the store already needs.
+
+### Why one fix covers both
+
+The runner never inspects which backend signed its credentials. It receives
+`expires_at`, mounts, and later decides reuse-versus-rebuild from that timestamp.
+Both backends report a truthful `Expiration` and both enforce it with 403. The fix
+therefore lives in backend-neutral places: make the requested TTL real, configurable,
+and never silently absent at signing time, and make the runner honor the expiry of
+the credentials it actually installed.
+
+## 5. EACCES as a remount trigger: false-positive analysis
+
+The issue proposes treating EACCES like ENOTCONN. Two distinct places could do
+that, with very different risk:
+
+- **The acquisition probe** (`isMounted`, `mount.ts:255`) already does. It treats
+  ANY `ls -A` failure as not-mounted, EACCES included. False positives are not a
+  realistic concern there: the session policy grants read, write, and scoped list
+  on the entire mount prefix (`_scope_policy`, `storage.py:132`), so no path
+  inside the mount can legitimately deny a root listing while the credentials are
+  alive. A root-listing EACCES implies dead or invalid credentials, and remounting
+  is the right response to both. One caveat: geesefs caches directory listings
+  (default `--stat-cache-ttl` 30s, `core/cfg/flags.go:1075`), so an `ls` within
+  the cache window can pass while writes fail. The probe alone therefore cannot
+  reliably detect a soft death, which is another reason not to build the fix on
+  probing.
+- **The mid-turn event watcher** (`containsTransportEndpointDisconnected`,
+  `runtime-policy.ts:136`) scans full ACP event payloads for marker strings.
+  "ENOTCONN" is distinctive; "EACCES" and "Permission denied" are not. Agents
+  legitimately produce them constantly (reading `/root`, failed `sudo`, quoting
+  error messages). Each false trigger would burn the single-shot remount budget
+  (`environment.ts:141`) and race a live harness against an unmount. Extending the
+  watcher to EACCES is the false-positive-prone half of the proposal, and it is
+  unnecessary once credentials outlive every turn. Deferred.
+
+## 6. Test infrastructure
+
+- **Runner**: vitest, `services/runner/tests/unit/*.test.ts`, run with `pnpm test`
+  from `services/runner`. The keep-alive dispatch already has a fake-engine seam
+  (`tests/unit/session-keepalive-dispatch.test.ts` injects a `KeepaliveEngine`
+  into the real `runWithKeepalive` + `SessionPool`), which is exactly where the
+  installed-lease and lease-window tests belong. The fake engine hands the dispatch
+  its own `SessionEnvironment` stand-in, so a test can stamp installed mount
+  expiries on it directly. Mount behavior tests live in
+  `tests/unit/sandbox-agent-mount.test.ts` with injectable `runGeesefs` /
+  `checkMounted` seams.
+- **API**: pytest, `api/oss/tests/pytest/`. Unit tests for the mounts service
+  exist at `unit/test_mounts_service.py`; acceptance tests for mounts at
+  `acceptance/mounts/`. `ObjectStore` signing is already covered at
+  `unit/test_mounts_injection.py:306-438`, whose `_CapturingPost`
+  (`test_mounts_injection.py:312`) replaces `aiohttp.ClientSession` and captures the
+  single STS POST body and headers. That is the seam for asserting `DurationSeconds`
+  and the minted token, with no new mocking layer.
+- Commands: `cd services/runner && pnpm test && pnpm run typecheck`;
+  `cd api && py-run-tests` (or targeted `uv run --no-sync pytest`).
+
+## 7. Prior art
+
+- Draft PR #5247 ("agent mounts", design issue #5215) introduced the durable
+  agent mount; `agent-mount.ts:3` references its plan document
+  (`docs/design/agent-workflows/projects/agent-mounts/plan.md`), which lives on
+  that branch, not on main.
+- `docs/design/mount-file-viewer/` documents the mounts file-listing UI on top of
+  the same service; no credential-lifetime logic.
+- The ENOTCONN detection and single-shot remount machinery
+  (`environment.ts:478-567`) is prior art for the hard-death half of this bug and
+  stays untouched.
+- The mounts service comment at `service.py:57-58` already states the failure
+  mode ("geesefs holds the creds without refresh, so a turn outliving this hits
+  ExpiredToken"); what it misses is that SeaweedFS capped the real lifetime to
+  900s and that the pool's expiry bookkeeping drifts.

+# Status
+
+**State**: planned and revised, awaiting Mahmoud's approval. No code changes made yet.
+
+- 2026-07-25: workspace created for issue Agenta-AI/agenta#5516. Research done
+  against the pinned versions (geesefs v0.43.0 source, SeaweedFS 4.37 source,
+  miniopy-async in the api venv). Root cause is threefold and differs from the
+  issue's framing in one important way: the observed 900-second lifetime is not
+  `storage.py`'s default (the service requests 3600s) but SeaweedFS capping the
+  session at the API's 15-minute web-identity JWT, compounded by the runner's
+  session pool overwriting its mount-expiry bookkeeping on every warm turn.
+- Chosen fix: configurable TTL env var, web-identity token lifetime aligned to the
+  requested duration, and fail-closed parsing of the STS expiry (API), plus an
+  installed-credential lease and a required-validity window of one worst-case turn
+  in the runner's session pool. Issue directions 1 (EACCES event sniffing) and 4
+  (RoleSessionName) deferred; rationale in plan.md.
+- 2026-07-25: plan.md revised after an external design review. The runner half now
+  records the expiry of the credentials actually installed in each mount instead of
+  patching the repark path, lease sufficiency is checked separately from identity,
+  a fixed 60-second clock-skew allowance was added, the STS paths fail closed on a
+  missing expiry, the TTL knob is wired through docker-compose, and the QA numbers
+  were made insensitive to turn timing. The default TTL (3600, measured in
+  production, with in-place refresh as the follow-up if churn hurts) and the source
+  of the validity window (the runner's own run limits plus the fixed skew constant)
+  are settled in the plan.
+- Next: approval of plan.md, then implementation on a GitButler lane with the unit
+  tests and the recorded live QA described there.
+
+One open question remains at the end of plan.md: whether the Daytona harness
+transcript mounts need their own lease entries.

Subject: [PATCH 128/139] fix(api): make mount-credential TTL real,
 configurable, and fail-closed

The web-identity JWT was hardcoded to 15 minutes, so SeaweedFS capped every
mount credential at 900s regardless of the requested 3600s. Mint the token
with the requested lifetime (capped at the 12h session ceiling), clamp
DurationSeconds into each backend's valid range, make the TTL configurable
via AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS, and raise instead of returning
never-expiring credentials when an STS response carries no usable Expiration.

Subject: [PATCH 129/139] fix(runner): track installed mount credentials and
 rebuild before they die

The session pool re-armed its expiry bookkeeping from each dispatch's fresh
sign, which never reaches the running geesefs daemons, so active
conversations reused mounts whose credentials had died (EACCES on every
path, issue #5516). Record the expiry of the credentials actually installed
at mount time, park from that installed lease, and evict to a cold rebuild
when the lease cannot cover a worst-case turn plus clock skew.

+# Decisions: what was chosen, why, and how to back each choice out
+
+Every decision this fix embeds, explicit or implicit, with its trade-off and the
+cheapest way to reverse it. Ordered from the ones that shape the fix down to
+mechanical details. "Backtrack" states what changing the decision costs later.
+
+## 1. Fix the two real defects, not the issue's headline remedies
+
+The issue proposed raising the TTL and adding refresh machinery. Research showed
+the requested TTL was already 3600 seconds; two defects made it a lie: the
+web-identity JWT was hardcoded to 15 minutes and capped every SeaweedFS session,
+and the runner's session pool overwrote its expiry bookkeeping on every warm turn
+with the expiry of credentials that never reached the running mounts. The fix
+repairs exactly those two defects.
+
+- Trade-off: none. This is smaller than any alternative and removes the root
+  cause instead of moving it.
+- Backtrack: not applicable; the defects are defects.
+
+## 2. Fresh credentials arrive by rebuilding at the turn boundary, not by
+refreshing a running daemon
+
+geesefs v0.43.0 offers no zero-machinery in-place refresh: it reads a
+credentials file exactly once (research.md section 3 rules the rewrite idea out
+against the vendored SDK source), and the two real refresh mechanisms
+(credential_process, the container-credentials endpoint) each add a
+credential-serving surface, with the remote variant putting API auth inside the
+agent-reachable sandbox. The session pool already evicts to a cold rebuild on
+credential grounds; the fix makes that designed mechanism truthful instead of
+adding a new one.
+
+- Trade-off: an active conversation rebuilds cold once per lease. At default
+  knobs the warm window is TTL (3600s) minus turn budget (2700s) minus skew
+  (60s), about 14 minutes, so long busy conversations pay a cold rebuild
+  roughly every 14 minutes. On the local sandbox that is sub-second-to-seconds;
+  on Daytona a credential eviction deletes the remote sandbox and the next turn
+  pays a full create. Before the fix those same conversations did not pay a
+  rebuild; they broke outright at minute 15.
+- Backtrack: if production shows the churn hurts, implement the
+  container-credentials endpoint (research.md section 3, mechanism 4). Nothing
+  in this fix blocks it; the lease bookkeeping stays correct either way.
+
+## 3. Default TTL stays 3600 seconds
+
+Raising the default to the SeaweedFS ceiling (43200s) would widen the warm
+window from ~14 minutes to ~11 hours, but every extra hour of lifetime is an
+hour a leaked prefix-scoped credential (and the now-matching web-identity JWT)
+stays usable.
+
+- Trade-off: more frequent cold rebuilds for long active conversations until
+  the rebuild rate is measured in production.
+- Backtrack: set `AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS` on the API service.
+  No code change; the clamps keep any value legal per backend.
+
+## 4. The eviction margin is the full worst-case turn budget, plus fixed skew
+
+A parked environment is reused only when its lease covers `now + total turn
+deadline + 60s`. The total deadline (default 45 minutes,
+`AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS`) is the longest a turn started now could
+still be running, so no turn can start on credentials it could outlive.
+
+- Alternative considered: margin from the idle timeout (5 minutes), which would
+  widen the warm window to ~54 minutes. Rejected because a single long turn
+  could then cross expiry mid-flight, which is the bug this fix exists to
+  remove.
+- Trade-off: the margin is pessimistic; most turns finish in seconds.
+- Backtrack: lower `AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS` if turns are known to
+  be short on a deployment; the margin follows it automatically.
+
+## 5. Clock-skew allowance is a fixed 60-second constant, not a knob
+
+`MOUNT_LEASE_SKEW_MS` covers API/runner/store clock differences and the seconds
+a rebuild spends mounting. It protects an invariant, and a third time knob that
+operators must relate to the other two invites mis-setting.
+
+- Backtrack: one constant in `session-identity.ts`.
+
+## 6. A lease too short for the turn budget warns and runs; it never fails
+
+When the TTL is below budget plus skew, even a fresh mount cannot satisfy the
+reuse window, so every dispatch rebuilds cold and logs `lease-short` naming both
+knobs. The stricter alternative, refusing to start or failing configuration
+validation, was considered and rejected: it would turn one mis-set number into a
+full outage, proceeding is never worse than the pre-fix behavior, and QA lowers
+the TTL on purpose.
+
+- Trade-off: a misconfigured deployment churns instead of stopping; the log
+  line is the only signal.
+- Backtrack: tighten the same branch in `coldAndPark` if operations later
+  prefers fail-fast.
+
+## 7. The lease tracks the cwd and agent mounts only
+
+`installedMountExpiries` records the two durable mounts. The Daytona harness
+session-directory and transcript mounts are excluded: they are signed seconds
+after the cwd mount with the same TTL, so their expiry is never the minimum and
+tracking them would add entries that cannot change the outcome.
+
+- Trade-off: if that signing order or TTL parity ever changes, the exclusion
+  argument breaks silently.
+- Backtrack: add fields to `InstalledMountExpiries` and stamp the two remote
+  session-dir mount sites; `installedMountLease` already reduces over whatever
+  entries exist.
+
+## 8. A re-park always describes the live environment
+
+`reparkOrEvict` keeps the live environment's secrets hash unconditionally. On
+the idle path the mismatch gate has already proven the live and incoming hashes
+equal; on the approval-resume path the resume deliberately ignores the incoming
+credentials, so adopting its hash would relabel an environment running old
+secrets as if it ran new ones. An earlier draft made this a per-call-site flag;
+the unconditional form removes a default that would have been wrong to forget.
+
+- Backtrack: none needed; this is an invariant, not a preference.
+
+## 9. The incoming credential epoch no longer carries an expiry
+
+Both park sites now derive `mountExpiresAtMs` from the installed mounts, so the
+expiry of the credentials signed per dispatch had zero readers. The parameter
+was removed rather than left as a plausible-looking dead input that would
+mislead a reviewer into thinking dispatch signs govern reuse.
+
+- Backtrack: re-add the second argument to `computeCredentialEpoch` if a future
+  consumer appears.
+
+## 10. Signing fails closed on a missing or unparsable STS expiry
+
+`_parse_sts_credentials` raises `MountStorageUnavailable` instead of returning
+credentials with no expiry, because the runner reads a missing expiry as "never
+expires" and one malformed response would silently disable the reuse bound. Both
+signing branches are STS, so no legitimate no-expiry path exists. A refused sign
+degrades the turn to mount-less, the same handling as any other sign failure; it
+does not fail the turn.
+
+- Backtrack: relax the raise back to `None` only if a store appears whose STS
+  legitimately omits `Expiration` (none known).
+
+## 11. The web-identity JWT lives as long as the requested TTL, capped at 12h
+
+Minting the token with the requested lifetime is what makes the TTL real on
+SeaweedFS. The cap (`_SEAWEEDFS_MAX_SESSION_SECONDS`, mirroring the compose
+`maxSessionLength: 12h`) keeps any token from outliving the longest session it
+could mint.
+
+- Trade-off: the internal token's replay window widens from 15 minutes to the
+  TTL. The token never leaves the API-to-store network hop. The pre-existing
+  sharp edge is unchanged and documented in research.md section 4: that JWT
+  presented without a session policy grants the whole bucket, so it must stay
+  inside the API trust boundary.
+- Backtrack: none sensible; a shorter token re-caps the credential lifetime,
+  which is the bug.
+
+## 12. Sub-900-second lifetimes are a SeaweedFS-only QA lever
+
+SeaweedFS hard-validates `DurationSeconds` in [900, 43200] but caps the
+effective lifetime at the web-identity token's expiry with no floor, so a low
+TTL takes effect through the token. AWS `GetFederationToken` has a hard 900
+floor, requires long-term IAM-user credentials (root is capped at 3600s), and
+was not exercised live; it is covered by the request-level unit tests and the
+analysis in research.md section 4. The runner half keys only off the
+STS-reported `expires_at`, which both backends report truthfully, so it is
+backend-neutral by construction.
+
+- Trade-off: the fast live reproduction exists only on SeaweedFS deployments.
+- Backtrack: optional staging pass on AWS with TTL 900 and a >15-minute active
+  conversation, as listed in plan.md.
+
+## 13. The TTL is read through the shared env object, with fail-fast parsing
+
+`MountsConfig.credentials_ttl_seconds` follows the repo convention (config via
+`env`, never `os.getenv` at call sites) and uses a `default_factory` so the
+variable is read when the config object is built, which keeps tests plain.
+Parsing goes through the file's existing positive-int helper: unset or empty
+falls back to 3600; garbage or a non-positive value raises at startup, matching
+how every other knob in `env.py` behaves. Constructor injection of the TTL into
+`MountsService` was considered and rejected as against the repo's convention.
+
+- Backtrack: trivial; it is one field and one call site.
+
+## 14. The mid-turn event watcher was not extended to EACCES
+
+The acquisition probe already treats an EACCES listing as not-mounted and
+remounts. Extending the mid-turn watcher (which scans agent event text) to
+"Permission denied" would false-trigger constantly on legitimate agent output,
+and becomes unnecessary once no turn starts on credentials that can die under
+it.
+
+- Backtrack: revisit only if a new failure mode produces mid-turn EACCES with
+  live credentials; the ENOTCONN watcher shows the pattern to copy.
+
+## 15. Per-mount RoleSessionName stays deferred
+
+Every mount still shares one STS session identity (`agenta-store`). Worth
+fixing on isolation grounds; orthogonal to expiry and left out to keep this fix
+reviewable.
+
+## 16. Deferred efficiency follow-ups (noticed, deliberately not done here)
+
+- Every warm dispatch still signs mount credentials that are then unused (only
+  the pool key and a project-id fallback consume the result). Skipping that
+  sign on warm hits needs a lazy-sign restructure of the dispatch path; out of
+  scope.
+- `webidentity._private_key()` re-parses the PEM on every sign; a one-line
+  cache is a safe follow-up outside this diff's files.
+
+## 17. QA knobs ship as first-class passthroughs in all seven compose files
+
+`AGENTA_MOUNTS_CREDENTIALS_TTL_SECONDS` (api service) and
+`AGENTA_RUNNER_RUN_TOTAL_TIMEOUT_MS` (runner service) were added to the OSS and
+EE dev/gh/gh.local/gh.ssl compose files, unset by default, so operators and QA
+can set them without editing compose files. The live reproduction in this PR
+uses exactly these knobs.

+- 2026-07-25: implemented (API commit acaa86e288, runner commit 290cfc244b) on
+  the worktree branch `worktree-fix-sts-mount-expiry-5516` (worktree used instead
+  of a GitButler lane, per Mahmoud). Mahmoud decided the one open question from
+  plan.md: the Daytona harness transcript mounts do not get their own lease
+  entries (deferred; argument recorded in decisions.md item 7). A four-angle
+  cleanup review (reuse, simplification, efficiency, altitude) was applied; the
+  register of every decision, including the review-sourced ones, is decisions.md.
+- 2026-07-25: live QA on a dedicated stack deployed from the worktree
+  (SeaweedFS backend). All four phases passed: the bug reproduced on demand with
+  the pre-fix runner (11 consecutive denied turns starting 20 seconds after the
+  120-second lease expired, all warm-continued onto the dead mount), the fixed
+  runner ran the identical cadence with zero denials across eight lease-cycle
+  rebuilds, the `lease-short` warning fired as designed at TTL 60, and a
+  22-minute soak at default settings showed exactly one `credentials-expiring`
+  cold rebuild at the 14-minute mark and no denial (the old behavior broke at
+  minute 15). One extra finding from the reproduction: a write acknowledged at
+  the expiry boundary was silently lost in the geesefs cache flush, so the
+  pre-fix behavior could lose acknowledged data, not just deny access.
+- Remaining follow-ups (not this PR): in-place credential refresh via a
+  container-credentials endpoint if the ~14-minute cold-rebuild cadence of long
+  active conversations proves costly in production (decisions.md item 2), the
+  EE/production deployment repos need the TTL passthrough when the knob should
+  become settable there, per-mount RoleSessionName, and an optional AWS staging
+  pass at TTL 900.

Subject: [PATCH 133/139] fix(frontend): surface a failed harness catalog
 instead of silently degrading

A null capability map has two causes: a schema with no x-ag-harness-ref (the
pre-catalog controls are correct), or a catalog the browser could not reach.
The drawer rendered both identically, so a failed request looked like a stale
frontend build and gave the user nothing to act on.

Track the query's error state and, when the schema did ask for the catalog,
show a retry notice above the basic controls.

Subject: [PATCH 134/139] fix(frontend): preserve freshest lastMessageAt when
 bumping session activity

Local turn-settle bump used Date.now() directly, which could overwrite a
newer server heartbeat under clock skew and briefly sink the session in
history. Use Math.max, matching the reconciler.

Subject: [PATCH 135/139] chore(deps): bump next from 15.5.18 to 15.5.21 in
 /web
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebuilt on top of current release/v0.106.1 instead of merging the
stale dependabot branch forward (it predated several since-merged
changes: the axios alignment fix, the native-tsc-trial scripts, and a
version bump, all of which the stale branch's diff would have
reverted).

Aligns oss and the repo-wide pnpm.overrides floor with ee, which was
already bumped to 15.5.21 in an earlier, narrower dependabot PR.
Includes the lockfile regen that bump was missing (agenta-playground-ui's
floating peer range doesn't auto-follow a floor bump; tightened to
>=15.5.21 so pnpm can't keep resolving 15.5.18 there).

Security-relevant: 15.5.21 fixes several CVEs — DoS in Server Actions,
a Middleware/Turbopack single-locale proxy bypass, SSRF via rewrite
destination hostnames, SSRF in Server Actions on custom servers, and
response-body cache confusion.

Verified: tsc --noEmit clean for both oss and ee, pnpm why next shows
a single resolved version workspace-wide, and `pnpm build-oss`
completes successfully.

Not fixed here: `pnpm build-ee` still fails on a pre-existing,
unrelated webpack error (react-syntax-highlighter's PrismAsync pulling
in refractor's ESM-only per-language subpaths) — confirmed present
identically before and after this bump, so it needs its own fix.

Subject: [PATCH 136/139] [5541] fix(frontend): parse skill frontmatter as YAML
 and isolate bundled-file editors

Uploading a skill package with a folded YAML description showed the literal
">-" in the Description field, and edits made just before switching bundled
files were dropped by the shared editor's 300 ms debounce.

- Parse SKILL.md frontmatter with js-yaml; accept name/description only as
  strings, and fall back to the body alone on invalid YAML.
- Key the bundled-file editor by selected index and disable its debounce so
  a file switch cannot cancel a pending edit or leak undo history.
- Cover the parser table in unit tests and the full upload flow in a new
  Playwright acceptance spec with an in-memory zip fixture.

Subject: [PATCH 137/139] fix(web): declare react-syntax-highlighter as an ee
 dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The agenta_cloud EE Docker build was failing:
"Module not found: ESM packages (refractor/x) need to be imported"
from react-syntax-highlighter's PrismAsync, for every one of
refractor's ~300 per-language subpaths.

EE recompiles oss's source directly (../oss/src/... in its own
webpack context) rather than consuming a built @agenta/oss package,
so it needs every package that source imports resolvable from its
own dependency tree. react-syntax-highlighter was declared only in
oss/package.json, so ee/node_modules/react-syntax-highlighter never
existed — oss had its own symlink into the pnpm store, ee had none.
Without it, Next's build-time module classification for this package
(bundle vs. external, ESM handling) diverged between the two apps
even though they share identical next.config.ts, next version, and
webpack setup, and oss's own build of the exact same route/component
chain succeeded throughout.

Fix: declare react-syntax-highlighter directly in ee/package.json,
matching oss's version.

Ruled out first: a next 15.5.18 vs 15.5.21 version mismatch (aligning
versions either direction did not change the failure) and adding
react-syntax-highlighter to transpilePackages (made things worse —
broke oss's previously-working build too). Verified the actual fix
with a fully clean rebuild (no turbo/next cache): `pnpm build-ee`
completes successfully end to end (8/8 tasks), and tsc --noEmit stays
clean for both apps.

Subject: [PATCH 138/139] test(api): add mtime regression + acceptance coverage
 for mounts file/archive endpoints
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a unit regression test pinning the epoch-ms/seconds mtime bug in
stream_mounts_archive, plus acceptance coverage for the shallow (depth=1)
listing and the download-all archive endpoint (/mounts/files/export) —
the two gaps called out in #5416. _rollup_recent_entries already had
coverage from #5411, so this PR doesn't touch it.

Closes #5416

Subject: [PATCH 139/139] test(api): address CodeRabbit feedback on mtime
 regression test

Clean up FakeMountStorage._mtimes on delete_keys so a recreated key
can't inherit a stale timestamp. Assert the zip member's converted
date_time explicitly, verified against the real stream_zip output, so
a regression that ignores mtime and falls back to datetime.now() would
still fail this test.
