Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-08-02 13:20 (PT) (00f548b0) and 2026-08-03 03:38 (PT) (fa9cd2c7), based on an automated review of all 24 commits in that window.

This pull request:

blas/ext/base

• Fix missing dtril/stril TS declarations and README ToC/link entries in blas/ext/base left out by 8a59dbb, which added the namespace registration in lib/index.js but not the corresponding docs/types/index.d.ts imports/interface entries or README updates (unlike dcopyWithin/gtril).

ml/base/loss/float64/squared-hinge-gradient

• In squared-hinge-gradient/docs/repl.txt (line 28, from 36bce0b), the return value description read "Squared Hinge loss gradient." — capitalized "Hinge" inconsistent with sentence case elsewhere in the file and sibling packages (e.g., squared-error-gradient); lowercased to "Squared hinge loss gradient."

Other

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Validation performed on the commit window:

• Style-guide compliance audit (docs/style-guides) of all changed files, cross-checked against established sibling packages (e.g., dtriu/striu/gtriu, squared-error-gradient).
• Bug scan of all introduced code (JS/C kernel pairs, documented example outputs, float64/float32 sibling consistency, native addon argument mappings, and the ml/base/sgd rename tree) — no runtime bugs found.
• Deliberately excluded: anything requiring interpretation or judgment (e.g., a sec ULP-tolerance choice in 4f852f8 that differs from the secd migration in 21df521 but may be intentional), and anything whose fix would require changes outside the window's diff.
