hotfix(v1.7.9): auth diagnostics and rate-limit exemptions

- Exempt /api/config/auth, /api/config/features, /health, /metrics from rate limiting
- Fix generic exception handler to return proper JSON for HTTPException instead of re-raising
- Add startup log with auth_enabled and version
- Add frontend console logging for auth config fetch errors
- Show 'Auth: OFF' or 'Auth: misconfigured' on auth button instead of empty text
- Add backend debug logging to /api/config/auth endpoint

+# AOC v1.7.7 Release Notes
+
+**Release date:** 2026-04-24
+
+---
+
+## Security Hardening
+
+This release is a focused security patch addressing findings from an internal audit. All users running AOC in production are encouraged to upgrade.
+
+### Webhook authentication (`/api/webhooks/graph`)
+- **ClientState validation** — Notifications now require a matching `WEBHOOK_CLIENT_SECRET`. Set this in your `.env` to the same value used when creating Graph subscriptions.
+- Rejects spoofed notification payloads with `401 Unauthorized`.
+
+### Rate limiting
+- **Redis-backed fixed-window rate limiting** is now enabled by default.
+- Per-category limits:
+  - `/api/fetch-audit-logs` — 10 requests/hour
+  - `/api/ask` — 30 requests/minute
+  - `/api/events/bulk-tags` — 20 requests/minute
+  - All other endpoints — 120 requests/minute
+- Returns `429 Too Many Requests` with a `Retry-After` header when exceeded.
+
+### SSRF protection for LLM calls
+- `LLM_BASE_URL` is now validated before every outbound request.
+- Blocks non-HTTPS URLs, localhost, link-local addresses (`169.254.169.254`), and all private IP ranges.
+
+### CORS enforcement
+- Wildcard (`*`) origins are **automatically stripped** when `AUTH_ENABLED=true`.
+- A startup warning is logged if an insecure CORS configuration is detected.
+
+### Content Security Policy
+- API and HTML responses now include a `Content-Security-Policy` header.
+- Restricts script sources to self, CDN origins, and MSAL auth library.
+
+### Audit trail integrity
+- The audit middleware no longer parses JWT tokens without signature verification.
+- Verified claims are now propagated safely via `contextvars`, eliminating audit log poisoning.
+
+### Standalone MCP server
+- Prints a prominent security warning on startup reminding operators that the stdio transport has no authentication layer.
+
+---
+
+## Operational Improvements
+
+### Bulk tag cap
+- `POST /api/events/bulk-tags` now refuses to update more than **10,000 events** in a single request.
+- Returns `400` with guidance to narrow filters.
+
+### Generic error responses
+- Internal exception details are no longer leaked in HTTP 500/502 responses.
+- Full stack traces remain in server-side logs.
+
+### Alert rule schema
+- `conditions` field now uses a strict Pydantic model (`AlertCondition`) instead of an unconstrained `list[dict]`.
+- Prevents stored data pollution from malformed rule payloads.
+
+### Docker Compose
+- MongoDB (`27017`) and Redis (`6379`) ports are no longer forwarded to the Docker host.
+- Internal services are reachable only via the Docker network.
+
+---
+
+## Configuration
+
+Add to your `.env`:
+
+```bash
+# Required if you use Graph webhooks
+WEBHOOK_CLIENT_SECRET=your-random-secret
+
+# Optional: disable rate limiting (not recommended)
+RATE_LIMIT_ENABLED=true
+RATE_LIMIT_REQUESTS=120
+RATE_LIMIT_WINDOW_SECONDS=60
+```
+
+---
+
+## Upgrade notes
+
+**No breaking changes.** Existing event data, tags, comments, and saved searches are preserved.
+
+After pulling:
+
+```bash
+export AOC_VERSION=v1.7.7
+docker compose -f docker-compose.prod.yml pull
+docker compose -f docker-compose.prod.yml up -d
+```
+
+---
+
+## Docker image
+
+```
+git.cqre.net/cqrenet/aoc-backend:v1.7.7
+```

 ## Completed in this PR
 All Phase 5 items marked done were implemented in v1.3.0–v1.5.0.
 Redis caching + async queue implemented in v1.6.0, switched to Valkey.
+UI polish (topbar, footer, clickable pills) in v1.6.1–v1.6.4.
+
+---
+
+## Phase 6: Multi-Tenancy (Premium) ⏸️
+Goal: allow MSPs to manage multiple client tenants from a single deployment.
+
+Status: **Planned — not started**. Architecture designed, pending validation of core features (SIEM export, alerting) in production first.
+
+### Architecture
+- Row-level isolation: `tenant_id` field on every MongoDB document
+- Each tenant has their own Microsoft Entra tenant + app registration credentials
+- Auth: user's JWT `tid` claim maps to tenant config automatically
+- Super-admin role for MSP staff to access all tenants
+
+### Implementation phases
+- **Phase 6.1** (2–3 days): Tenant model & registry, tenant-aware data layer, per-tenant Graph API auth
+- **Phase 6.2** (1 day): Tenant-scoped API routes, tenant-specific config endpoints
+- **Phase 6.3** (2 days): Frontend tenant switcher, tenant name display, admin page
+- **Phase 6.4** (1 day): License gating — signed JWT `LICENSE_KEY` gates multi-tenant mode
+
+### Licensing model
+- Single-tenant: remains MIT/free
+- Multi-tenant: premium feature requiring a signed license key
+- License key is a JWT with claims: `plan`, `max_tenants`, `exp`, `features`
+- Offline license generation tool included
+
+### Effort estimate
+~7–9 days total. Deferred until SIEM export and alerting are battle-tested.
