Repository-level tooling (tools/)

Scripts and audit artifacts at the monorepo root (not book/tools/, which is textbook-specific).

Layout

Path Role
audit/ Math/HTML/PDF audit scripts for the Quarto book (see audit/README.md).
release-smoke/ Playwright smoke checks for published sites; see release-smoke/package.json. Generated reports live under release-smoke/reports/ (timestamped JSON). Safe to delete old reports when pruning; regenerate by re-running smoke.
phase_b/phase_g/, lint_calibration/ One-off cleanup and lint calibration manifests from past passes (JSON/Markdown). Kept for traceability; not imported by CI or application code. Remove or archive only when maintainers agree the history is no longer needed.
validate_playbook.py Standalone validation helper; see file docstring for usage.

Relationship to book/tools/

Use book/tools/ for BibTeX, git hooks wiring, quarto scripts, and book prose validators. Use tools/ here for cross-cutting audits, release smoke tests, and historical phase outputs.
