[Planeshifter]

Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-07-26 14:39 PDT (f027a8a) and 2026-07-27 01:40 PDT (02d9b41).

This pull request:

• blas/ext/base/zcartesian-product: Fix stdlib_strided_zcartesian_product_ndarray's stride buffer type: sa was declared CBLAS_INT sa[ 2 ] (int32 on non-ILP64 builds) but passed to stdlib_ndarray_is_row_major, which expects int64_t *strides. The callee was reading garbage past the array and could pick the wrong row-/column-major branch, silently corrupting output placement. Changed to int64_t sa[ 2 ], matching zcartesian-square. Introduced in c19010a; see lib/node_modules/@stdlib/blas/ext/base/zcartesian-product/src/main.c.
• math/base/special/exp2: Fix test.native.js (aa63474 — introduces ULP diff testing): five assertion messages read 'return expected value' instead of 'returns expected value', inconsistent with test.js from the same commit and the rest of the file. Corrected all five to 'returns expected value' in lib/node_modules/@stdlib/math/base/special/exp2/test/test.native.js.
• number/uint64/parse: Fixes an article typo introduced in 0404059: "an 64-bit unsigned integer" → "a 64-bit unsigned integer" in lib/node_modules/@stdlib/number/uint64/parse/README.md, aligning the Notes section with the phrasing already used elsewhere in the same README and in sibling packages.

Validation. The 24 commits in the window were reviewed by four independent passes: two style-compliance audits comparing new packages against established sibling packages and the guidelines in docs/style-guides, and two bug scans over the full diff (including the new wxsa ndarray wrapper family, gwxmy, zcartesian-product C sources, number/uint64/parse parsing logic, and the ml/base/sgd-classification penalty packages). Only findings that were independently re-verified against the repository were retained. Deliberately excluded: subjective suggestions, style preferences not required by the style guides, and anything requiring changes outside the reviewed diff to validate (e.g., a possibly-unused EPS require in math/base/special/acscdf tests and a pre-existing "Rate parameter." wording in regenerated REPL help data).

This PR is a draft for maintainer audit; it intentionally does not close any issues.
