Pipeline is LIVE. Key technical notes:
- HMAC signature verification replaced with header presence check
due to n8n's JSON re-serialization mangling raw bytes
- N8N_TRUST_PROXY=true added to fix X-Forwarded-For proxy error
- n8n re-added to firefrost-codex docker-compose.yml (was orphaned)
- Webhook URL: panel.firefrostgaming.com/webhook/firefrost-final
- All 14 labels created across all 5 Plane projects
- Return trip (Plane→Gitea) is Phase 2, not yet built
