chore: rename C source files according to convention

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• Renames src/from_word.c to src/main.c in number/float32/base/from-word and src/to_word.c to src/main.c in number/float32/base/to-word, updating each package's manifest.json source entry to match, so that both packages use the C source filename already used by the rest of the namespace.

Namespace summary

Audited @stdlib/number/float32/base.

• Members: 18 (13 native, gypfile: true). No member is wholly generator-owned, so all 18 participated.
• Features analyzed: 18 structural and semantic features — file tree, package.json top-level/scripts/stdlib key sets, manifest.json keys, README section set and heading order, test/benchmark/example filenames, public signature, return kind, validation prologue, error construction, JSDoc shape, and source dependencies. Several structural features were additionally voted within the 13-member native sub-population.
• Features with a clear majority (≥75%): 14. Conformance is high across the board — package.json key sets, scripts, manifest.json keys, return kind, and test/example filenames are all at 100%.
• Features without a clear majority (excluded): 4 — README heading order (max 7/18, 38.9%), public-signature arity (12/18, 66.7%), keywords family (12/18, 66.7%), and source dependencies (max 4/18, 22.2%).

The keywords and arity splits are not drift: they separate bit-level type utilities from arithmetic operations. They were excluded rather than forced.

number/float32/base/from-word

The number/float32/base/from-word package renamed src/from_word.c to src/main.c and updated the corresponding src entry in manifest.json; 11 of 13 native packages in the number/float32/base namespace (84.6%) already use src/main.c, and this brings the package in line with that convention. The build derives sources solely from manifest.json via include.gypi/binding.gyp, and src/Makefile hardcodes no filename, so no build configuration changes are required. The public header include/stdlib/number/float32/base/from_word.h is untouched and the renamed file compiles cleanly; this change is behavior-neutral.

number/float32/base/to-word

In number/float32/base/to-word, src/to_word.c retained the legacy package-named filename against the namespace's 84.6% src/main.c convention (11/13 packages) and the repository's 95.1% convention (1645/1729). Renamed to src/main.c and updated the corresponding src entry in manifest.json; the public header include/stdlib/number/float32/base/to_word.h and the build graph (binding.gyp, include.gypi, src/Makefile) resolve the source list dynamically and required no changes. Behavior-neutral: the file compiles cleanly and no other reference to to_word.c exists in the repository.

Validation

Checked:

• Structural extraction across all 18 members (file tree, package.json/manifest.json key sets, README headings, test/benchmark/example filenames).
• Semantic extraction via one agent per package reading lib/main.js, lib/index.js, and lib/validate.js/lib/assign.js/lib/polyfill.js where present.
• Three-agent drift validation — semantic review, cross-reference against tests/benchmarks/build config/tooling, and structural review. The correction in this pull request was returned confirmed-drift unanimously by all three.
• Post-apply: a repository-wide grep for from_word.c/to_word.c returns no remaining references, and both renamed sources compile cleanly under gcc -c -Wall against the package include path.

Deliberately excluded:

• Intentional deviations. assert lacks lib/main.js, benchmark/benchmark.js, and docs/repl.txt because it is a namespace aggregator, matching number/float64/base/assert and math/base/assert. to-float16/lib/main.js carries no JSDoc because it is the Math.f16round builtin alias behind the standard builtin-vs-polyfill dispatch. from-binary-string is the only member that validates its argument, which is its documented contract and asserted by its tests. identity keeps C benchmarks under benchmark/c/native/, a distinct and actively used convention (477 packages repository-wide, 219 carrying both paths) reproduced in the float64 and complex identity packages.
• Generator-owned sections. The missing ## See Also blocks in significand, to-float16, ulp-difference, and assert are emitted by remark-stdlib-related from @stdlib/namespace/pkg2related data, which has an empty entry for significand and no entry for the other three. This is generator state rather than a README defect and is not addressed here.
• Features without a clear majority, listed in the namespace summary above.
• A single-precision keyword gap in ulp-difference, dropped on materiality — a lone one-line metadata tweak, and the package also lacks the plain single keyword, so adding one keyword would leave it off-pattern regardless.

No test expectations, public signatures, or observable behavior are changed by this pull request.

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 pull request was prepared by Claude Code running an automated cross-package drift audit of the number/float32/base namespace. AI was used to survey the namespace, compute per-feature majority patterns, adversarially validate each candidate finding, and draft this description. The change itself is a mechanical file rename plus a one-line manifest.json update in each package; it was verified by a repository-wide reference grep and by compiling both renamed sources. Reviewers should confirm the src/main.c naming convention is in fact desired for these two packages, since the change is consistency-only and carries no functional benefit.
