Re-review follow-ups (non-blocking quality items):
Tests:
- moderation H1 specs now assert exact `→ 403` instead of bare .rejects.toThrow(),
so a spurious 500 can no longer masquerade as "revocation worked".
- config: added case-insensitivity (upper/mixed-case placeholder) and the
len==32/31 boundary cases for validate_secrets.
- rate_limiter: added the trailing-comma empty-entry case for client_ip (must
fall back, not return "").
(Backend unit tests: 35 pass.)
Docs:
- README: note that with APP_ENV=production a placeholder .env makes the app
refuse to boot and Caddy wait unhealthy — reason is in `docker compose logs app`.
- SECURITY-BACKLOG + sse.rs comment: document that a mid-session ban does not
tear down an already-open SSE stream (new tickets are blocked; low blast radius).
