| N-H4 | Rate limit only on 1 AI endpoint | High | ✅ FIXED | `@rate_limit` added to: `generate-key-themes`, `moderator/advance`, `autonomous/start`, `conversation/decision`, `conversation/intervene`, `moderator/end-session` |
| N-P5 | LLM endpoints return generic errors | High | ✅ FIXED | Structured error messages with actionable context |
| N-P6 | `focus_groups.py` 500 with no log | High | ✅ FIXED | `logger.error()` added before all 500 returns (update, delete, add/remove participant) |

### Medium

| ID | Finding | Severity | Status | Resolution |

---

## Accepted Risk Items

| ID | Finding | Rationale |
|----|---------|-----------|
| F-C1 | JWT in localStorage | httpOnly cookies require backend cookie proxy rewrite; CSP header already mitigates XSS risk; accepted by engineering team |
| F-H1 | Client JWT no signature check | Inherent browser limitation; server validates signature on every request; client-side decode is only for UX (e.g., checking expiry before requests) |
| F-M4 | Verbose console.log in dev | Already gated by `import.meta.env.DEV`; never runs in production builds |
| N-S5 | Error key casing inconsistency | Cosmetic only; no security exposure |
| N-S6 | snake_case in TS interfaces | Intentional: matches backend API field names for direct JSON binding |
