chore: clean-up

[Planeshifter]

Description

Follow-up fixes for commits merged to develop between 2026-07-09 12:56 PDT (669fa61) and 2026-07-10 02:46 PDT (ae1746f9) — 26 first-parent merges, dominated by the new blas/ext/base/{sfill-equal,sfill-not-equal,dfill-not-equal,dfirst-index-equal,sfirst-index-equal} packages, the Uint64Array type addition, and the math/base/special/kernel-betainc C port.

This pull request fixes six isolated, diff-confirmed defects surfaced by a two-track review (style-guide compliance × bug scan, four independent reviewers) of that window.

blas/ext/base/dfirst-index-equal

• Fix declare const dfirstIndexEqual: Routine; → declare var in blas/ext/base/dfirst-index-equal/docs/types/index.d.ts:106 (from adf21e7) — every other package in @stdlib/blas/ext/base, including sfirst-index-equal, declares the top-level export with var; this was the lone const outlier in the namespace.
• lib/node_modules/@stdlib/blas/ext/base/dfirst-index-equal/docs/repl.txt:5: the 412de11 docs cleanup dropped the trailing period on the top-level summary and merged it into the following paragraph; restored the period and the blank line, matching the .ndarray variant below it.

blas/ext/base/sfirst-index-equal

• ecdd8f1 mis-paired the <!-- lint disable maximum-heading-length --> comment in lib/node_modules/@stdlib/blas/ext/base/sfirst-index-equal/README.md:238 — the closing tag was another disable, leaving the rule off for the rest of the file. Changed it to enable.
• Fixed the .ndarray help-section heading in sfirst-index-equal to actually read {{alias}}.ndarray(...) instead of {{alias}}(...), matching the dfirst-index-equal convention (ecdd8f1, lib/node_modules/@stdlib/blas/ext/base/sfirst-index-equal/docs/repl.txt:60).

types

• Fix double space before => in the Uint64ArrayLike get accessor JSDoc example (lib/node_modules/@stdlib/types/index.d.ts:850); brings it in line with the single-space convention used elsewhere in the file. Introduced in ec14192.
• ec14192: fix missing space before closing bracket in Uint64ArrayLike JSDoc example, buf[ (2*i)] = value.hi; → buf[ (2*i) ] = value.hi;, to match the docs/style-guides/javascript array-index spacing rule already followed by the adjacent Uint64Array example (lib/node_modules/@stdlib/types/index.d.ts:860).

Review scope. The 26 commits in the window were split for review:

• New blas/ext/base packages (sfill-equal, sfill-not-equal, dfill-not-equal, dfirst-index-equal, sfirst-index-equal) — each cross-checked against sibling dfill-equal for template drift, and cross-checked against each other for copy-paste / precision-swap errors.
• math/base/special/kernel-betainc C port (6512a7a) — checked line-by-line against assign.js for control-flow / branching / special-case parity.
• blas/base/dsyr and blas/base/ssyr enum refactors (5c57284, c519b51) — checked for parity against the pre-existing dtrmv matrix-triangle-resolve-str pattern.
• types Uint64Array addition (ec14192), 9 docs: commits, namespace / TypeScript declaration updates, test: / bench: / chore: / build: fixups — checked for typos, style-guide compliance, and any unintended behavior change in the fix commits themselves.

Deliberately excluded. Any concern that required interpretation, a judgment call, or reading files outside the diff to validate was dropped — including a stylistic observation about STDLIB_CONSTANT_FLOAT32_SMALLEST_NORMAL being used as the Modified-Lentz "tiny" replacement in a double-precision continued fraction (safe, mirrors the JS reference; only a Boost-idiom preference), and one comment carry-over from the JS source in kernel-betainc/src/main.c:496 (faithful port of unmodified upstream text). See the local audit report for the full drop list and rationale.

Disclosure

Opened as a draft by an automated commit-review routine. Findings were surfaced by four independent reviewer agents (two style-compliance, two bug-scan) over the last-24h develop window, de-duplicated, and re-verified against the working-tree diff before any edit. Each fix is exactly the mechanical change described in its bullet — no scope expansion, no drive-by cleanup. A maintainer should audit before promoting out of draft.
