Auto-sync generation failure (b1001d7)

Auto-sync generation failed for docs SHA `b1001d7290cf3347b9338acf9a642601ca4bddfb`.

Opened automatically by `.github/workflows/generate.yaml`. Check the [workflow run](https://github.com/HarperFast/skills/actions/runs/34828846628) for the full error.

**Common causes and fixes (Story 4 in docs/plans-archive/docs-driven-skills.md):**
- Source file renamed or moved — update `sources[].path` in `rules.manifest.yaml`.
- Section heading renamed or removed — update `sources[].section`.
- Must-cover assertion no longer in source — update `must_cover` or the section changed.
- Regeneration dropped a fact its sources still document — the model restructured a
rule and lost content. Re-run generation, or if the removal is correct, record it
under `rules[].allow_dropped` in the manifest.

After fixing, regenerate locally (`npm run generate -- --docs-path `) and open a fix PR.

Start with the linked workflow run and .github/workflows/generate.yaml to identify the generation error, then compare the affected source entries in rules.manifest.yaml with Story 4 in docs/plans-archive/docs-driven-skills.md. Run npm run generate -- --docs-path locally after correcting the relevant path, section, must_cover, or allow_dropped entry. Done means generation succeeds and the fix is submitted in a PR.
