Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-09-01 16:38 (PT) (fd6046b) and 2026-09-02 01:39 (PT) (0c7f769).

This pull request:

• stats/base/dists/arcsine/logcdf:
  • Fixed malformed return statement in .../arcsine/logcdf/src/main.c:56 (94b9253): double space after LN2, spurious spaces before stdlib_base_asin/stdlib_base_sqrt parens, redundant outer parens, and trailing space before ;. Now matches call-spacing conventions and the JS implementation.
• stats/base/dists/truncated-normal/pdf:
  • Fixed extra blank line before the C signature code fence in stats/base/dists/truncated-normal/pdf/README.md, introduced in ad203e8; brings it in line with every other dists README (single blank line).
  • Fixed the Doxygen summary line-wrapping in ad203e8 for stats/base/dists/truncated-normal/pdf: joined the hard-wrapped summary in src/main.c and include/stdlib/stats/base/dists/truncated-normal/pdf.h back onto a single line, matching every other stats/base/dists header/source in the repo (text otherwise unchanged).
  • Fixed manifest.json indentation for stats/base/dists/truncated-normal/pdf (ad203e8) from 4 spaces to 2, matching every sibling stats/base/dists manifest; content unchanged, verified via parse-compare.

Validation. All 18 commits merged to develop in the review window were audited for (1) stdlib style-guide compliance (compared against established reference packages, e.g. laplace/pdf, gamma/pdf, dlast-index-equal/glast-index-equal) and (2) objective bugs within the diffs (formula transcription, addon arity/order, manifest deps vs. includes, search/stride logic, ULP assertion argument order). Deliberately excluded: subjective suggestions, style preferences not required by the style guides, and anything whose fix would require touching code outside the window's diffs (e.g., a latent NaN-parameter edge case in truncated-normal/pdf where the new C code exactly mirrors the pre-existing JS implementation — fixing C alone would break JS/C parity).
