Summary

Pre-deploy audit of main (caac782) found 2 BLOCKERs that prevented production deploy. Both fixed. 5 MAJORs + 9 MINORs documented in docs/PRE_DEPLOY_AUDIT_2026-05-10.md as follow-up work.

B-1 — Container crashed on boot

render.yamlDockerfile:14-17pip install -r requirements.txt. The pre-fix requirements.txt was missing 4 of 11 declared runtime deps:

  • structlog — module-level in app.py:14boot crash
  • flask-limiter — module-level in app.py:16-17boot crash (would be next)
  • openai — lazy in app.py:591 → silent 5xx on /api/personalize/structure
  • pillow — lazy in app.py:637 → silent 5xx on /api/personalize/run

Plus 4 version drifts vs uv.lock (flask, playwright, requests, gunicorn).

Empirically reproduced:

$ python3.12 -m venv /tmp/audit-venv
$ /tmp/audit-venv/bin/pip install -r requirements.txt   # PRE-FIX
$ /tmp/audit-venv/bin/python -c "import app"
ModuleNotFoundError: No module named 'structlog'

Fix: uv export --format requirements-txt --no-dev --no-emit-project --no-hashes > requirements.txt. Now a regenerable build artifact pinned to lock-resolved versions for all 11 declared deps + transitives. Eliminates the drift class entirely.

Post-fix import app registers all 10 routes including /health, /api/personalize/*, /api/client-errors, /download.

B-2 — .env.example missing

24 env vars consumed across app.py / kratos_clone/* / personalize/* had no operator-facing reference. OPENAI_API_KEY fails per-request (lazy OpenAI() constructor at personalize/openai_client.py:80) — silent until first call to /api/personalize/*. Operators reading render.yaml (only PORT set there) had zero discoverability for the key.

Fix: .env.example documents all 24 vars grouped by lifecycle ([boot] / [request] / [test-only]) and consumer module.

Audit report

docs/PRE_DEPLOY_AUDIT_2026-05-10.md (266 lines):

  • Findings table with severity + file:line evidence
  • Detail per finding (impact, remediation, recommended follow-up)
  • Verification matrix (mypy, ruff, pytest, bandit, pip-audit, empirical boot)
  • Operator sign-off checklist for the actual deploy

Top deferred items:

  • M-3 — cryptography v41.0.7 transitive (6 CVEs, soft-gated in CI). Bump path: uv sync --upgrade-package cryptography.
  • M-5 — Playwright 1.57 Chrome-for-Testing memory regression (microsoft/playwright#38489) — relevant on Render's 512 MB free tier; mitigated today by --workers 1.
  • M-1/M-2/N-1/N-2 — CLAUDE.md and WORKFLOW.md doc drift (claimed P2 items remaining = 7, actual 0; aspirational stages claimed = 3, actual 0; "52 tests" → 210; "$0.32 per run" cost claim unverified).

Test plan

  • Fresh venv install of post-fix requirements.txtimport app succeeds, 10 routes registered (replicates Dockerfile path 1:1)
  • uv run mypy --config-file pyproject.toml → Success in 21 source files
  • uv run ruff check kratos_clone/ scripts/ → All checks passed
  • uv run ruff format --check kratos_clone/ scripts/ → 11 files already formatted
  • uv run pytest -q → 210 passed, 2 skipped
  • uv run bandit -r personalize/ kratos_clone/ scripts/ app.py --severity-level medium (CI scope) → Medium 0, High 0
  • After merge: Render auto-deploy succeeds; operator sets OPENAI_API_KEY per .env.example; /health returns {"status":"ok"}; /api/personalize/structure returns 200 on a tiny brief

    • Regenerated project dependencies with complete transitive dependency tracking.

Review Change Stack

Container deploy via render.yaml -> Dockerfile -> requirements.txt
crashed on first `import app` because requirements.txt was missing
4 of 11 declared runtime deps (structlog, flask-limiter, openai,
pillow), with 4 additional version drifts vs uv.lock.

Reproduced empirically: fresh venv install of pre-fix requirements.txt
followed by `python -c 'import app'` raised
`ModuleNotFoundError: No module named 'structlog'` at app.py:14 —
gunicorn would never have bound. Personalize endpoints would have
5xx'd silently even after that, since openai+pillow are lazy-imported
in route handlers.

Fixes
-----
- requirements.txt: regenerated via
  `uv export --format requirements-txt --no-dev --no-emit-project --no-hashes`.
  Now matches uv.lock at the lockfile-resolved versions for all 11
  declared deps + transitives. Build artifact, regenerable.
- .env.example: created. 24 env vars across app.py, kratos_clone/*,
  personalize/* documented, grouped by lifecycle ([boot] / [request] /
  [test-only]) with defaults and one-line descriptions. OPENAI_API_KEY
  flagged as the per-request fail-mode.
- docs/PRE_DEPLOY_AUDIT_2026-05-10.md: full pre-deploy audit report.
  2 BLOCKERs fixed in this PR; 5 MAJORs + 9 MINORs documented as
  follow-up work (CLAUDE.md/WORKFLOW.md doc drift, transitive CVEs in
  cryptography v41, in-memory rate limiter trap, Playwright 1.57
  Chrome-for-Testing memory regression, Dockerfile hardening, Procfile
  dead code, bandit scope gap on downloader.py).

Verification
------------
- Empirical post-fix venv: `import app` succeeds, 10 routes registered.
- mypy: Success in 21 source files.
- ruff check + format: clean.
- pytest: 210 passed, 2 skipped (live OpenAI tests gated).
- bandit (CI scope): Medium 0, High 0.
- bandit (incl. downloader.py): Medium 0, High 1 (pre-existing N-9,
  non-security md5 use for filename hashing).

The line numbers cited in the findings table for flask-limiter and pillow are inconsistent with the detailed evidence section (lines 100-102) and the actual source code in app.py. flask-limiter is imported on lines 16-17, and the pillow dependency is triggered by the import on line 637.

Fixed in 084c126. Findings table now reads app.py:14 (structlog), app.py:16 (flask-limiter), app.py:591/637 (openai/pillow lazy) — matching the detail section and app.py source. Thanks for catching the inconsistency.

Confirmed real finding — OSV scanner correctly identifies urllib3==2.6.2 as vulnerable to GHSA-38jv-5279-wg99 (CVE-2026-21441, HIGH-sev decompression-bomb on redirect-following with preload_content=False). I locally verified the bump (uv lock --upgrade-package urllib3 resolves to urllib3==2.7.0; post-bump pytest 210/2 skipped, mypy 21 src OK, boot OK).

Deferred to a dedicated dep-bump PR, not landed here, for two reasons:

  1. Scope discipline. This PR's BLOCKER is the boot crash (missing structlog + flask-limiter). Dep bumps are a separate scope by design — see docs/PRE_DEPLOY_AUDIT_2026-05-10.md finding M-3, which now folds urllib3 in alongside cryptography v41.0.7 (6 CVEs, transitive of openai). Both deserve the same dedicated PR with full CI re-run.
  2. The boot fix unblocks Render deploy by itself. urllib3's redirect-decompression vector requires a malicious server in the redirect chain — in this codebase, the exposed call site is kratos_clone/capture.py visiting user-supplied URLs. The capture endpoint is rate-limited and not on the hot path; the fix is important but not deploy-gating.

The audit doc (commit 084c126) has been updated to call this out explicitly under M-3 and the recommended follow-up sequencing now reads: uv lock --upgrade-package cryptography --upgrade-package urllib3.

Pinging this for visibility — happy to land it here instead if @fbmoulin prefers, but the cleaner path is the bump-PR.

Findings table cited app.py:18 for flask-limiter and app.py:636 for the
pillow lazy import. Actual: flask-limiter is L16 (`from flask_limiter
import Limiter`), pillow's import chain triggers at L637 (`from
personalize.pipeline import run_pipeline`). Detail section already had
the correct numbers; table now matches.
…6-21441)

CodeRabbit's OSV scanner flagged urllib3==2.6.2 as vulnerable to
CVE-2026-21441 (HIGH-severity decompression-bomb when following HTTP
redirects with preload_content=False). Transitive of requests; the
exposed call site is kratos_clone/capture.py visiting arbitrary
user-supplied URLs.

Bumped via `uv lock --upgrade-package urllib3` (resolves to 2.7.0),
requirements.txt re-exported. Verified post-bump: app boots (10 routes),
pytest 210 passed + 2 skipped, mypy 21 src Success.

Note: uv.lock is also bumped locally to urllib3==2.7.0 but is too large
to push via the API tool. A follow-up commit from a regular `git push`
context will sync the lockfile, OR a `uv lock --upgrade-package urllib3`
re-run on `main` after merge will produce the same result.
M-3 split: urllib3 2.6.2 -> 2.7.0 was bumped in commit 67ad8ce
(closes the CVE-2026-21441 finding). Cryptography 41.0.7 (6 CVEs)
remains deferred to its own bump PR — bumping it requires
re-resolution of openai's transitive tree.

Follow-up sequencing item #3 renamed "Cryptography bump PR" with the
urllib3 entry removed.
