chore: propagate recent fixes to sibling packages

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-04-20T16:07:19-04:00 and 2026-04-21T03:37:01-07:00 (SHA range 7a025ca74..1089250db) to sibling packages sharing the same defect.

fix: — wrong validation package (source b7f85c29d)

Array-dtype assertion @stdlib/array/base/assert/is-complex-floating-point-data-type checks against @stdlib/array/dtypes, but these consumers resolve dt from ndarray dtype strings (either via getDType(x) or opts.dtype), so the guard would misfire on ndarray-only dtypes. Swapped for the @stdlib/ndarray/base/assert/... variant already used by broadcast-scalar and broadcast-scalar-like.

Source: b7f85c29d

Targets:

• lib/node_modules/@stdlib/ndarray/from-scalar/lib/main.js
• lib/node_modules/@stdlib/ndarray/from-scalar-like/lib/main.js

chore: — missing stdlib/no-new-array disable directives in *-by tests (source 1089250db)

The stdlib/no-new-array rule is error (see etc/eslint/rules/stdlib.js:4475), so intentional sparse-array construction via new Array( N ) requires an explicit // eslint-disable-next-line stdlib/no-new-array on the preceding line. 40 sibling *-by test files under math/strided/ops/ and math/strided/special/ carried the idiom without the directive; added 92 directives total. For the ops/{add,sub,mul}-by files, consecutive x = and y = sparse-array assignments each received their own preceding directive, since eslint-disable-next-line only silences the single following line.

Source: 1089250db

Targets (40 files):

• math/strided/ops/add-by/test/{test.main,test.ndarray}.js
• math/strided/ops/mul-by/test/{test.main,test.ndarray}.js
• math/strided/ops/sub-by/test/{test.main,test.ndarray}.js
• math/strided/special/{abs,abs2,acos,acosh,acot,acoth,acoversin,ahaversin,asin,asinh,atan,atanh,avercos,besselj0,besselj1,bessely0,bessely1,binet,cbrt,cos,sin,sqrt}-by/test/test.*.js (the specific test.main.js / test.ndarray.js files still missing the directive; full list in the local report)

Validation

• Pattern search scope: ndarray namespace for the validation-package swap; math/strided/{ops,special}/*-by test files for the lint-disable directive.
• Candidate enumeration: rg / script-driven search, cross-checked by a sonnet Explore agent. Results reconciled against a Python pass that classifies each sparse-array line as needs-fix or already-fixed based on the preceding line.
• Independent validation: opus agent audited (a) Pattern A target files to confirm dt originates from ndarray dtype context (verified via getDType / opts.dtype / DEFAULT_CMPLX), and (b) a sampled cross-section of Pattern B sites to confirm the idiom is intentional sparse-array construction and the preceding line lacks a disable directive. All sampled sites returned confirmed.
• Style: patches match source-commit style verbatim — single-line module-path swap for Pattern A, tab-indented // eslint-disable-next-line stdlib/no-new-array preceding each new Array(...) for Pattern B.

Deliberately excluded

• Sites already fixed by the source commit (math/strided/special/sin-by/test/test.ndarray.js) and sibling *-by files that already had the directive (e.g. acovercos-by, abs-by/test.main.js, atan-by/test.main.js).
• chore: add missing npm engine constraint to stats/base/dists/*/ctor (187e14109) — touches only package.json, excluded per chore-propagation scope rules.
• docs: update namespace table of contents (0f62461c9, f38217702) — auto-generated ToC updates with no generalizable signature.
• chore: clean-up native wrappers (e3862232d): all 7 napi/argv-*/lib/native.js sites matching the pattern are already in the corrected form.
• chore: clean-up (9cc43caf4) targeting napi/argv-booleanarray: effectively reverted by e60e084fe, so the guarded form is now the canonical shape; no propagation target.
• docs: propagate recent fixes to sibling packages (59d0640a1): the "does not perform rotation" → "a rotation" typo fix and argv-bool "number → boolean" typo fix have no remaining sites in the ndarray rotation namespace or type-specific argv-* packages.

Disclosure

This PR was authored by Claude Code running the fix-propagation routine: it enumerated fix: / chore: / docs: commits merged to develop in the preceding 24 hours, derived pattern signatures, searched for sibling sites via rg, validated each candidate with an opus audit agent, and applied the propagated patches. A human maintainer will audit before promoting out of draft.
