Summary

Remediates critical security findings C1–C6 and unblocks the two failing PR checks (Lint & Test, Vercel).

Security (C1–C6)

  • CSRF restored on session APIs; client sends X-CSRFToken
  • /v1 user_id bound to API key owner (IDOR fix)
  • Fail closed on missing/invalid TOKEN_ENCRYPTION_KEY in production
  • Untracked .venv / __pycache__
  • get_db imports → modules.database
  • POST /api/setup_tokens → permanent 410 Gone

CI fixes

  1. Lint & Test — Narrowed ruff to fatal selects; Fernet key fallback; file-backed SQLite (not :memory:); flake8 F811/F841/F824 cleanups; Python 3.11 f-string SyntaxError in media_handler.py / location_service.py.
  2. Vercel — Hobby plan rejects cron schedules that run more than once per day. Switched to daily UTC schedules; documented Pro upgrade path in DEPLOY.md. Only VERCEL_ENV=production is treated as production so preview deploys do not hard-exit without secrets.

Merge

Synced with main (security audit doc #11).

Test plan

  • Local: ruff fatal select clean, flake8 E9/F6/F7/F8 clean, 62 pytest passed
  • Vercel deployment succeeded on Hobby-compatible crons
  • GitHub Actions Lint & Test green on latest SHA

Deployment failed for project post-pilot with the following error:

Hobby accounts are limited to daily cron jobs. This cron expression (0 * * * *) would run more than once per day. Upgrade to the Pro plan to unlock all Cron Jobs features on Vercel.

Simple conflicts combined. Intent conflicts resolved as:
- CSRF: protect session APIs; exempt v1/stripe/cron/embed only
- setup_tokens: always 410 Gone (OAuth-only, matches Wave A)

- Treat only VERCEL_ENV=production as production (preview no longer
  hard-fails without TOKEN_ENCRYPTION_KEY at import time)
- Narrow ruff CI to fatal-error rules; add Fernet key fallback when
  CI_TOKEN_ENCRYPTION_KEY secret is unset
- Fix location_service.py apostrophe SyntaxError that broke py_compile

- Merge main (#11 audit doc); resolve TODO.md conflict
- vercel.json: daily cron schedules (Hobby rejects hourly/minute)
- CI: file-backed SQLite; flake8 F811/F841/F824 cleanups
- conftest forces test DB path so :memory: cannot break tokens table
