Propagating fixes merged to develop between 2026-04-19 and 2026-04-20 to sibling packages that carried the same copy-paste defects.

Description

What is the purpose of this pull request?

This pull request:

• napi/argv-bool — propagates f3dfe11 ("docs: update descriptions"). Commit f3dfe11 swept 33 napi/argv-* README files to correct a copy-paste error in the **err** parameter description, replacing the wrong validated type ("a number") with the correct one for each package. For napi/argv-bool, which validates a JavaScript boolean and stores into bool *out, the phrase now correctly reads "a boolean" in lib/node_modules/@stdlib/napi/argv-bool/README.md (line 140).

• ndarray/base/rot{l,r}90 — propagates f756fa1 + c2c401e ("docs: update note"). Commits f756fa1 (README) and c2c401e (repl.txt) fixed a missing article in ndarray/rotr90, changing "perform rotation" to "perform a rotation". The same defect was present in the base package siblings; this propagation applies the identical one-word fix to lib/node_modules/@stdlib/ndarray/base/rotl90/README.md and lib/node_modules/@stdlib/ndarray/base/rotr90/README.md (both at line 77).

Validation. Candidate sites were found by searching the full repository for the defect signatures in scope:

• Pattern search scope: lib/node_modules/@stdlib/**/benchmark/benchmark.size.{float32,float64}.js for 869c9da (swapped dtypes — 0 sites beyond those already fixed); lib/node_modules/@stdlib/blas/**/benchmark/*.js for cd1a4d3 (wrong b.fail message — see exclusions); lib/node_modules/@stdlib/napi/argv-*/README.md for f3dfe11; rg "perform rotation" repo-wide for f756fa1/c2c401e.
• Two independent validation agents read each candidate file in full; an adaptation agent produced the per-site wording for the adaptive f3dfe11 fix; a style-consistency pass confirmed spacing and primitive-vs-typed-array wording conventions matched the source commits.

Deliberately excluded. The cd1a4d3 pattern ('should not return NaN' → 'should return an ndarray') surfaced 24 candidate benchmark files across blas/{s,d}{dot,swap}, blas/tools/swap-factory, and blas/ext/*. Every one was rejected: the remaining b.fail( 'should not return NaN' ); calls in those files guard genuine scalar isnan(...) checks (the ndarray-type guards in those same files already use the correct 'should return an ndarray' message). The 869c9da pattern had no propagation sites — sibling benchmark.size.float{32,64}.js files pass dtype as a positional argument rather than an options-object literal, so the filename/dtype mismatch does not occur. No needs-human sites remained after filtering.

Disclosure

This PR was authored by Claude Code running a fix-propagation routine over the last 24 hours of develop. Candidate source commits were classified into patterns; sibling sites were enumerated with rg, then independently validated (two validation agents), adapted, and style-checked before any patch was applied. Only sites confirmed by both validation passes and the style agent are included.
