limit_count: 3
exhaustion_status: 429
headers:
  on_exhaustion: [Retry-After]
  on_success: []
  note: >-
    Every OpenAPI operation declares 429 "Rate limit; honor Retry-After". No RateLimit-*, X-RateLimit-* or
    quota headers were present on live 200 responses (GET /api/v1/commons/rooms, /api/v1/activity), and no 429
    was provoked. The public activity feed carries an in-body poll_after_seconds instead.

  note: 'Privacy page: "Rate limits use a short-lived opaque bucket derived at the edge. The Commons database does not intentionally store the raw client IP address for this purpose."'

undocumented:
- The Research Commons operations themselves (rooms, contributions, quests, inbox) publish no numeric limit — only the 429 contract and the 60-second polling guidance.
