docs: fix signatures

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-07-10 12:54 PDT (e713916) and 2026-07-11 00:41 PDT (4da2dcf) to sibling packages carrying the same defect.

Pattern: missing .ndarray prefix on ndarray-variant REPL signature header

Commit e713916 corrected the .ndarray variant signature header in blas/ext/base/sfirst-index-equal/docs/repl.txt — the alternative-indexing section's header line read {{alias}}( N, ... ) rather than {{alias}}.ndarray( N, ... ), so REPL ? help displayed the wrong signature. The same defect is present in three sibling blas/ext/base packages: in each docs/repl.txt, the second signature block is documented as the alternative-indexing variant (mentions "alternative indexing semantics", accepts offsetX, example calls {{alias}}.ndarray(...)), but its header omits the .ndarray prefix. Fix is one line per file: prepend .ndarray to the header.

Validation

• Search scope. **/docs/repl.txt files under lib/node_modules/@stdlib/, filtered to files that (a) contain both a bare {{alias}}( header with no offset parameter and a bare {{alias}}( header with an offset parameter, and (b) contain no {{alias}}.ndarray( header. This bounded the candidate set to exactly the three *index-of files above.
• Two independent Opus validation agents each read every candidate file in full and confirmed that (a) the flagged header sits above a section whose description explicitly reads "using alternative indexing semantics", accepts an offsetX parameter, and whose Examples block already calls {{alias}}.ndarray(...); (b) a distinct main-variant signature (no offset) lives at the top of the same file; (c) prepending .ndarray is a safe, self-contained one-line edit.
• Adaptation pass confirmed the source patch shape applies verbatim (no per-site tailoring, no cross-file cascade).
• Style-consistency pass confirmed spacing (single space inside parens, comma-space argument separators) and the blank-line separation from the preceding block match the post-fix sfirst-index-equal reference exactly.

Deliberately excluded:

• The dfirst-index-equal/docs/repl.txt sentence-terminating period and paragraph-break fix from e713916: a repo-wide search for the same signature (description sentence ending without a period, followed by a continuation paragraph on the next line without an intervening blank line) returned no other REPL doc with the same defect.
• The sfirst-index-equal/README.md <!-- lint disable maximum-heading-length --> → enable correction from e713916: candidate READMEs (blas/ext/base/{gdiff,ddiff,sdiff}, blas/base/cgemv) carry a related but structurally different defect (multiple unclosed disable directives, each requiring insertion of a paired enable — not a disable→enable transform). The fix shape is not a direct analog of the source patch and would need adaptive per-site inserts. Logged for a future run.
• The dfirst-index-equal/docs/types/index.d.ts declare const → declare var change from e713916: a repo-wide search for ^declare const \w+: Routine; in **/docs/types/index.d.ts returned zero matches. The source commit closed the last remaining site.
• feat: commits in the window (sreplicate/dreplicate package additions, gammaincinv C implementation, TypeScript declaration updates): not fix patterns.
• docs: update namespace table of contents (31d535d, stdlib-bot): generator-owned files.

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 (two Opus validation passes, an adaptation pass, and a style-consistency pass) before commits were applied in the primary worktree. A maintainer should audit and promote out of draft.
