chore: propagate recent develop fixes to sibling packages (2026-06-05)

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-06-04 14:06:38 -0500 (39f37bf) and 2026-06-05 02:06:31 -0700 (6b0591c) to sibling packages with the same underlying defect.

Pattern: drop redundant genericndarray clause from flatten-{,from-}by overloads

typedndarray<T> already extends genericndarray<T>, making the union typedndarray<unknown> | genericndarray<unknown> in the Options<W> generic constraint redundant. The genericndarray import is retained in both files since other overloads reference it.

• 15a731b9 (refactor: remove redundant generic constraint in blas/ext/base/ndarray/gsorthp``)
• c26d8b58 (refactor: remove redundant generic constraint in blas/ext/base/ndarray/gsort``)
  • @stdlib/ndarray/flatten-by
  • @stdlib/ndarray/flatten-from-by

Pattern: PascalCase interface name in assert/is-well-formed-string

Renames interface isWellFormedString to interface IsWellFormedString in the TypeScript declaration, updating the declare var type reference accordingly; the export-value name isWellFormedString is unchanged. Aligns with every other assert/is-* package (IsString, IsBoolean, etc.) and the convention established in 608e415c.

• 608e415c (fix: rename interface to PascalCase LastIndexOfinblas/ext/last-index-of``)
  • @stdlib/assert/is-well-formed-string

Validation

• Search scope: per pattern, scoped to the source commit's namespace first (blas/ext/base/ndarray/* and ndarray/* for the redundant-constraint sweep; assert/is-*, array/base/cu*, math/base/special/*, and blas/ext/* for the PascalCase-interface sweep), widened to all lib/node_modules/@stdlib/**/docs/types/*.d.ts where the pattern signature warranted it.
• Two independent opus validation passes confirmed at every candidate site that (a) the defect is present as cited, (b) surrounding context does not change the semantics — for the redundant-constraint pattern, that typedndarray<T> indeed subsumes genericndarray<T> and the simplification does not narrow accepted inputs; for the PascalCase pattern, that the docs/types/test.ts does not reference the camelCase interface name as $ExpectType, which would cascade — and (c) the proposed patch matches the source commit's exact shape.
• A sonnet style-consistency pass verified that each replacement matches the surrounding declaration style (default = typedndarray<T> preserved on the simplified constraint, single-line overload retained, export = <value> lines untouched).

Deliberately excluded

• fix: type orderparameter asLayout`` propagation (a601344e / `3bf760c6`): the four remaining `blas/ext/base/cartesian-` siblings (`dcartesian-power`, `scartesian-power`, `gcartesian-power`, `gcartesian-square`) already type `order` as `Layout` — no propagation sites.
• docs: normalize dtype description in random/hypergeometric`` (fdfc2baa): the `real-valued or "generic"` defect appears nowhere else; sibling `random/*` packages either use `real-valued floating-point or "generic"` (correct prose for the `real_floating_point` dtype kind) or already use `real or "generic"` (correct for integer-output distributions).
• docs: correct @throws description for pulse duration (b2ef3a33): the only remaining sibling, simulate/iter/pulse, validates duration >= period (not duration > period) and so the docstring must be less than the period is correct as-is — different semantics from the bartlett/hann/lanczos/etc. pulses already patched.
• PascalCase rename for math/base/special/sincosd (Sincosd vs SinCosd), array/base/cusome (Cusome vs CuSome), and array/base/cunone (Cunone vs CuNone): one of the two validation agents flagged needs-human on each because the per-package PascalCase form requires a sibling-convention call; will land in a follow-up.
• The active strideX/offsetX rename sweep across blas/ext/base/* (f766a248, 1a35c429, 9f94bda2, a18215d3, e74dd953, 45710f8f, 37b53d20): each remaining sibling is being landed as its own commit by the namespace owner — propagating in bulk here would duplicate that workflow.
• Autogenerated artefacts (assert TS decls regen c415485e, REPL namespace docs ec39d31a, related-packages sections 3d01e36f, namespace list 6b0591c): generator-owned files.

Disclosure

This PR was authored by Claude Code on behalf of @Planeshifter as an automated propagation of fixes merged to develop over the prior 24 hours. Candidate source commits were filtered for generalisable patterns, sibling sites located via grep-able pattern signatures, and each proposed patch independently validated by parallel reviewer agents (two opus validation passes plus a sonnet style-consistency pass) before commits were applied in the primary worktree. A human will audit and promote the PR out of draft.
