Summary

  • The scheduled `Generate New Article` workflow has been failing every day for 10+ consecutive runs (back to 2026-04-19). All failures occur in `compile / publish_article` → Publish Individual Post.
  • Root cause: post `2026-02-13` produces a LaTeX compile error (`Missing $ inserted` near `h^*(n)`), and `pdfgenr` then unconditionally copies a non-existent `index.pdf`, raising `FileNotFoundError` and exiting the job. Every subsequent post (including each new daily article) gets blocked behind this single bad article.
  • This PR makes `pdfgenr` resilient: if no PDF is produced, it logs a warning, cleans up `.tmp/`, and returns `False`. The caller then skips writing the sha256 stamp so the post will be retried on the next run.
  • Also braces the bare `` superscript in `2026-02-13/index.md` (`h^(n)` → `h^{*}(n)`) to address the specific lualatex error.

Test plan

  • Re-run the `Generate New Article` workflow (or wait for the next scheduled run).
  • Confirm `compile / publish_article` reaches Commit and Push Changes without exit-code-1.
  • Confirm `public/blog/2026-02-13/index.pdf` is committed (or, if the math fix wasn't enough, that the post is logged as skipped and posts after it still publish).
  • Spot-check that 2026-02-14 onwards begin compiling — they have been queued but unreached for ~75 days.

fix: skip posts with failed LaTeX compile instead of crashing publish…
5b4dcce 
… job

The daily publish workflow has been failing for 10+ runs because pdfgenr
unconditionally copies index.pdf even when lualatex produced no output,
turning one bad article (2026-02-13) into a hard block on every
subsequent post.

- pdfgenr now checks for the PDF after texcomp, logs and returns False
  when missing, and only writes the sha256 hash on success so failed
  posts are retried on the next run.
- Brace the bare star superscript in 2026-02-13 (h^* -> h^{*}) which
  the lualatex log flagged as "Missing $ inserted".
