- Restrict CORS to known rSpace domains (no more open wildcard)
- Add tiered rate limiting per IP (anon vs authenticated, per endpoint tier)
- UA filtering blocks scrapers/scanners, allows browsers and AI agents
- Prompt injection sanitization: strip MI_ACTION markers, system tags, and
known attack patterns from user-supplied content before LLM ingestion
- Space access control: private/permissioned spaces gate MI data to members
- Auth required on /triage, /execute-server-action, data-driven /suggestions
- MCP guard: require auth or agent UA for /api/mcp/*
- Anonymous WebSocket cap: max 3 per IP with proper cleanup on close
- Knowledge index + conversation memory gated to members+ (viewers get
public canvas data only)
