chore: clean-up

[Planeshifter]

Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between ce67b15b and 89717ddc (2026-07-12 → 2026-07-13). Each item was independently verified against the diff, the sibling reference package, and — for the costi slice — the package's own test assertions.

This pull request:

fft/base/fftpack/costi

• Example/README for fft/base/fftpack/costi (ce67b15b) slice the workspace at 3*N+2 instead of 3*N, skipping past the integer-factor region defined by the file's own layout table and confirmed by test.js:304-305 — the runnable example prints zeros instead of the radix factors; fix workspace.slice( (3*N)+2, (3*N)+2+nf ) to workspace.slice( 3*N, (3*N)+nf ) in examples/index.js:45 and README.md:144.
• Fix stray 'value2' assertion message in lib/node_modules/@stdlib/fft/base/fftpack/costi/test/test.js (line 303, ce67b15b) to 'returns expected value', matching every other assertion in the file.

random/betaprime

• Files missed by the betaprime → beta prime pass in b59aade7: lib/node_modules/@stdlib/random/betaprime/docs/repl.txt (3 occurrences) and lib/node_modules/@stdlib/random/betaprime/docs/types/index.d.ts (8 occurrences) still say "betaprime distribution"; update both to "beta prime distribution" for consistency with the rest of the package.

number/uint64/base/get-high-word

• Fixed copy-paste artifacts from float64 sibling get-high-word in f23740ac: README.md and docs/repl.txt documented signature param as x while lib/main.js/TS decl use a, and README.md/examples/index.js:36 invoked new Uint64.of(...) despite of being a static factory, not a constructor.

blas/ext/base/gfill-less-than

• 89717ddc cleans up cargo-cult in gfill-less-than: dropped a stray eslint-disable-line max-len in lib/main.js:46 that gfill-equal's identical line doesn't have, and removed the redundant var on the x re-declarations in docs/repl.txt:44,98 to match every other gfill-* sibling.

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Validation. Each candidate finding was cross-checked against the actual working-tree file (line/content match), against a sibling reference package under the same parent directory (e.g. gfill-equal for gfill-less-than), and — for the costi off-by-two — against the package's own test assertions (test.js:304-305, which pin the factor region to 3*N, (3*N)+1). Findings that survived only on a single reviewer's read and could not be independently re-verified from the diff were dropped. Deliberately excluded: (a) suggestions to add explanatory comments / Notes bullets that no style-guide rule requires; (b) the costi layout-table example inside lib/main.js JSDoc (workspace.slice( (3*N)-2, (3*N)+2 )), which predates this window and is out of scope; (c) any change that would require touching code outside the 24h diff to remain correct.

AI Assistance

When authoring the changes proposed in this PR, did you use any kind of AI assistance?

• Yes
• No

If you answered "yes" above, how did you use AI assistance?

• Code generation (e.g., when writing an implementation or fixing a bug)
• Test/benchmark generation
• Documentation (including examples)
• Research and understanding

Disclosure

If you answered "yes" to using AI assistance, please provide a short disclosure indicating how you used AI assistance. This helps reviewers determine how much scrutiny to apply when reviewing your contribution. Example disclosures: "This PR was written primarily by Claude Code." or "I consulted ChatGPT to understand the codebase, but the proposed changes were fully authored manually by myself.".

This PR was drafted by a scheduled review routine (Claude Code): four independent reviewer agents scanned the last 24 hours of develop commits for objective bugs and unambiguous style-guide violations; only findings that were independently re-verified against the diff and a sibling reference package are included, and each fix was applied narrowly to the exact line and re-read before commit. A human maintainer will audit and promote from draft.
