chore: propagate recent develop fixes to sibling packages (2026-07-10)

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-07-09 14:56 PDT (669fa61) and 2026-07-10 02:46 PDT (ae1746f9) to sibling packages carrying the same defect.

Pattern: bracketed probability {density,mass} function link in distribution READMEs

Commit 2180fed wrapped "probability density function" in […][pdf] on the top-level blockquote of stats/base/dists/cauchy/{pdf,logpdf}/README.md. The same defect is present in 28 sibling READMEs: the blockquote quotes the phrase as plain text while the file already defines the [pdf]: (or [pmf]:) link-reference at the bottom.

• 2180fed (docs: add link)
  • stats/base/dists/{beta,betaprime,erlang,exponential,gamma,invgamma,laplace,lognormal,normal,t}/{pdf,logpdf}
  • stats/base/dists/{f,pareto-type1,rayleigh,truncated-normal,wald,weibull}/pdf
  • stats/base/dists/binomial/{pmf,logpmf}

Pattern: test require path in single-function test file

Commit 3109ac2 corrected the require path in blas/ext/base/dfirst-index-equal/test/test.dfirst_index_equal.js from the ./../lib Routine wrapper to the specific ./../lib/dfirst_index_equal.js implementation — the test.<name>.js test targets the main function, not the .ndarray variant, so it must bind the specific implementation. The two other newly added blas/ext/base packages with a matching test.<snake_case>.js file carry the same defect.

• 3109ac2 (test: fix require path)
  • blas/ext/base/dfill-not-equal
  • blas/ext/base/sfill-not-equal

Pattern: .ndarray description missing precision qualifier

Commit 412de11 rewrote blas/ext/base/dfirst-index-equal's descriptions to specify "double-precision floating-point strided array" instead of the generic "strided array". Sibling package blas/ext/base/dfill-not-equal has this correction applied everywhere except the .ndarray variant description in README.md:83 — every other description in that package (main-form README block, JSDoc in lib/**, docs/repl.txt, docs/types/index.d.ts, C header + src/main.c, package.json) already reads "double-precision floating-point strided array elements".

• 412de11 (docs: fix descriptions)
  • blas/ext/base/dfill-not-equal (README.md .ndarray description only)

Pattern: brittle exact-length assertion in niladic enum benchmarks

Commit d32732a replaced if ( out.length !== 3 ) { b.fail( 'should return an array of length 3' ) } in ndarray/index-modes/benchmark/benchmark.js with if ( out.length < 2 ) { b.fail( 'should return an array of strings' ) } so the benchmark keeps passing when new index modes are added. Three sibling enum-listing benchmarks carry the same brittle exact-length pattern.

• d32732a (bench: fix assertion)
  • ndarray/orders
  • blas/base/layouts
  • array/byte-orders

Pattern: isnan → isnanf in single-precision and complex64 benchmarks

Commit 945328a swapped isnan for isnanf in benchmarks operating on Float32 / Complex64 data across blas/base/{ccopy,cswap} and strided/base/{cmap,smap,mskunary,nullary,unary}. Direct siblings in blas/base (s* single-precision routines) and blas/ext/base (c* complex64 routines) still bind isnan from @stdlib/math/base/assert/is-nan despite operating on Float32 values via 'dtype': 'float32' random arrays or Complex64Array views.

• 945328a (chore: clean-up)
  • blas/base/{sasum,saxpy,scopy,sdot,sdsdot,snrm2,sscal,sswap} (all 4 benchmark variants each)
  • blas/base/scabs1 (benchmark.js, benchmark.native.js)
  • blas/ext/base/{cindex-of-column,clast-index-of-row} (all 4 benchmark variants each)

Pattern: bracket spacing in enum()-mapping test assertions

Commit 945328a also fixed obj[ o[i] ] → obj[ o[ i ] ] (missing spaces inside the inner index bracket, per docs/style-guides/javascript) across eleven enum-mapping tests. Four sibling enum()-mapping test files still carry the same style violation.

• 945328a (chore: clean-up)
  • ndarray/input-casting-policies (2 occurrences)
  • ndarray/output-dtype-policies (2 occurrences)
  • ndarray/base/dtype-enums (1 occurrence)
  • ndarray/index-modes (1 occurrence)

Validation

• Search scope. Per source pattern: for 2180fed, stats/base/dists/*/{pdf,logpdf,pmf,logpmf}/README.md; for 3109ac2, blas/ext/base/*/test/test.<snake_case>.js files with a matching sibling lib/<snake_case>.js; for 412de11, the newly added blas/ext/base/{dfill-equal,dfill-not-equal,sfill-equal,sfill-not-equal,sfirst-index-equal} sibling packages, every description-carrying file (README, docs/repl.txt, docs/types/index.d.ts, include header, lib/**, src/main.c, package.json); for d32732a, **/benchmark/benchmark.js files matching the niladic enum-listing + hardcoded-length-check idiom; for 945328a (isnan→isnanf), all benchmark/benchmark*.js under blas/base, blas/ext/base, strided/base binding isnan and operating on Float32 or Complex64 data; for 945328a (spacing), all **/test/test.js matching the enum()-mapping idiom (hasOwnProp( obj, o[ i ] ) + isNonNegativeInteger( obj[ o[i] ] )).
• Two independent Opus validation agents and a style-consistency pass confirmed the defect at each candidate site by reading each file in full, cross-checking the surrounding package's convention, and rejecting sites where semantics or intent differed. Search agents that read every candidate file already ruled out sites where the fix was previously applied or the pattern didn't hold.
• Style-consistency. Every patch reproduces the source commit's exact mechanical shape — no naming, message, or JSDoc drift; where the source commit's message on the same line was reused (e.g. 'should return an array of strings'), the propagation carries the same string.

Deliberately excluded:

• The 96 additional blas/ext/base/{sapx*,sdsapxsum*,sdssum*,sdsnansum*,ssum*,snansum*,ssumkbn*,ssumors*,ssumpw*,sxsy,snancount,sapxsumors,sapxsumpw,sapxsumkbn2} benchmarks matching the isnan→isnanf pattern. Same defect and same mechanical shape, but well outside the source commit's direct sibling scope (which was limited to blas/base complex64 and strided/base benchmarks); batching them into a separate propagation round keeps this PR's scope tight and makes the isnan-typing sweep easier to review as its own change. Logged for the next run.
• e7884bb7 (docs: fix example — missing .ndarray qualifier in dfill-equal/docs/types/index.d.ts): repo-wide regex sweep (validated against the pre-fix commit) confirmed zero recurrences elsewhere in blas/ext/base.
• 2ad0b70 (docs: document empty-matrix return value in lapack/base/iladlr/lib/iladlr.js): the only sibling ila-prefixed LAPACK routine, iladlc, already carries the same ## Notes block (added incidentally in a18ec63 one day earlier). No other ila* routines exist in lapack/base.
• Cauchy sibling READMEs that already applied the bracketed […][pdf]/[…][pmf] link (46 files) — not the same defect.
• The 5488831 (style: fix line wrapping, dfirst-index-equal/docs/repl.txt) and ae1746f/442d4f0 (docs: fix heading for sspr/dspr) source commits: neither pattern recurs at any sibling site. For the spr heading, the two sibling packed BLAS routines in-tree (sspmv/dspmv) already show order in their .ndarray heading; the non-packed s{yr,ymv,yr2} and d{syr,syr2} variants take strides (sa1,sa2) instead of order, so the fix doesn't propagate to them.
• The array/{full-like,empty-like,nans-like,zeros-like} docs (source 669fa61, "docs: fix examples to use supported dtypes"): zeros-like and nans-like already scope their dtypes(...) call correctly; full-like and empty-like skip dtype validation entirely and empirically iterate every dtype without error. No genuine bug propagation target.
• refactor: add support for enums (5c57284, c519b51) and every feat: commit in the window: not fix patterns.

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 generalizable patterns, sibling sites located via grep-able pattern signatures, and each proposed patch independently validated by parallel reviewer agents before commits were applied in the primary worktree. A maintainer should audit and promote out of draft.
