## REMOVED Requirements

### Requirement: AiOps public behavior SHALL remain isolated
**Reason**: Stage 6B temporarily preserved the legacy `/api/ai_ops` path only to make the Chat SSE cutover atomic. Stage 7 removes the remaining Supervisor/Planner/Executor orchestration so `/api/chat` is the single diagnosis entry required by ISS-014.

**Migration**: Bundled and external consumers MUST submit diagnosis requests to the named-event SSE `POST /api/chat`. There is no compatibility endpoint or legacy message-wrapper parser.
