PyCForge 1.3.62 documentation cleanup
Date: 2026-10-28

Removed the superseded 0.15.2 and 0.16.0 PDF manuals and their generator.
The generator's 22 conversion sources and expected outcomes are retained as
fixtures/typed_scope_loop_file_cases.json and exercised by
tests/test_typed_scope_loop_file_examples.py.

HELP.md and docs/HELP_AUTHORING.md now direct maintainers to current HTML Help.
PYPI_RELEASE.md is one current, version-derived procedure with no historical
install/upload instructions or retired document-build requirements. The current
Help verification replaces the retired document gate. MANIFEST.in excludes PDF
files, and the distribution verifier rejects PDFs and the retired generator.
Historical engineering specifications, release notes and immutable evidence
retain their original context. Product runtime and SDK catalogue bytes are
unchanged from the prior 1.3.62 handoff.

Validation completed:
- 58 focused tests and 537 subtests passed. This includes all 22 preserved
  conversion fixtures, source Help checks, release checks and distribution
  documentation guards, including case-insensitive PDF rejection.
- Current Help verification passed: 30 pages, five categories, 81 Python
  examples, 49 Runtime and 32 Typed native comparisons, five API examples,
  four C callers, three module examples and three README examples.
- README rendering passed with exactly the four approved image links.
- All 938 maintained runtime-package source files are byte-identical to the
  previous source tree; this includes the engine-owned SDK landscape. The
  wheel ships 932 of these files and is reused without changing its bytes.
- All 22 preserved fixture sources and expected results exactly match the
  removed generator's data. No PDF remains in maintained source.
- README, package version and dependency metadata are unchanged at 1.3.62.

Scope: documentation, release tooling and source packaging maintenance. The
complete engine/SDK suites from the original handoff were not rerun; their
records retain their original scope. Focused current checks and byte identity
support this maintenance. Final archive checks, sizes and hashes are in the
accompanying updated PyCForge-1.3.62-SDK-0.2.0-Verification.txt.

The revised source archive supersedes the earlier unpublished 1.3.62 source
handoff. The existing wheel, SDK packages and math conversion import remain
unchanged. Nothing has been published by the assistant.

The user reported outdated documentation text at Libraries.io. That page
returned HTTP 403 to automated retrieval, so its displayed content was not
independently inspected. Local cleanup does not establish that the external
listing has refreshed. No external listing was modified or contacted.
