Retarget OIDC / OAuth after DID and local-first - #1310

#277 assumed server-hosted Agents and a public-key add-on flow. Identity is now did:ad:agent:{pubkey}; writes are client-signed. Record that OIDC belongs on the control-plane session (a better magic-link), not on atomic-server AUTH or commits. Connector OAuth stays a separate importer problem.

SSO against the operator's IdP, connector refresh tokens, and a later OAuth AS all belong on always-on atomic-server. That is local config, not a control-plane client. Commits and resource AUTH stay Ed25519; OIDC only gates the envelope index. HostMode enrollment is unchanged until an explicit grant says otherwise.

Drop closed-product names, billing, and control-plane strategy from the OIDC/OAuth write-up. The feature is optional IdP config on this node. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Authorization-code flow with the node as confidential RP. Two cookies: OIDC session fetches the envelope; Ed25519 atomic_session is still resource AUTH. First visit mints locally; a returning device unwraps with passkey or recovery. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Sign in with the IdP must not also demand a passkey or recovery code. After a valid ID token the node unwraps with a node-held KEK and releases the Agent secret. Commits stay client-signed; the operator of this node is trusted with that identity. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Record the threat table. Prefer a short-lived issued/session agent behind the same button; GET /oidc/secret of the root Agent is the implementable fallback and a key-exfiltration API. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
JWT-in-signature and node-as-signing-oracle fight forever-commits, peer verify, and offline. The Atomic-shaped version is a short-lived issued agent: same one-click OIDC UX, Ed25519 still on the wire. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
OIDC-only login: node holds the root, browser generates a short-lived keypair, root signs a SessionCert. Commits stay Ed25519. write lists still name the root. Iroh AUTH must treat cert-chain as the person. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Authorization-code + PKCE against the operator IdP is unchanged. A valid id_token mints a SessionCert instead of becoming a Bearer header on /commit. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Leaving Google is a Settings action with step-up OIDC, not the login path. Unlink deletes the node's custodial wrap and must not mint a second identity if they click the button again. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
SessionCert in validate_signature and AUTH is the hard part; the OIDC dance is ordinary. Absent config, nothing changes. Record Google and generic issuer setup for the operator, not the end user. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
Spell out the verifier path: session Ed25519, then cert, then rights for the root via one effective_agent helper. Maps to validate_signature, AUTH, check_write, admit, and genesis write-list insert. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>

What this is
A reconsideration of #277. No protocol or server code yet.
Decision
OIDC-only login is a CA: root Agent on the node, browser-generated session Agent, compact SessionCert. Stock authorization-code OIDC; token-exchange into the cert, not Bearer on
/commit. Export + unlink so Google is reversible.How verifiers check session keys

Absent IdP config, nothing changes. The costly work is SessionCert in
validate_signature+ AUTH. The OIDC plugin is ordinary. Operator sets issuer/client/secret; end users only click the button.
