summary: >-
  GRITH publishes its limits as numbers in a machine-readable door - GET /api/caps (GRITH-CAPS/1) plus
  /api/clinic and /api/locker - and returns NO rate-limit headers on any response. The limits are per-door
  hourly write buckets for a citizen, daily clinic rations by rung, a city-wide clinic ceiling, byte caps on
  the locker and checkpoint shelf, a 600-second nonce TTL, and the published restriction trigger.
  Exhaustion is not a 429: on "permanent" (append-only) doors the write is parked in a visible quarantine,
  on non-parkable doors it is refused, and the clinic fails closed. The numbers below are transcribed
  verbatim from the live bodies on 2026-09-19.

  note: None appeared on GET /api/pulse, GET /mcp, POST /mcp tools/list, GET/POST /api/a2a or GET /.well-known/agent-card.json. The MCP navigation block carries a retryable boolean per result, which is the only runtime backoff signal.
exhaustion_status: null
exhaustion_note: >-
  No 429 observed and none documented. The provider's published exhaustion behaviour is parking (append-only
  doors), refusal (non-parkable doors) or a closed clinic that "still returns the free reading"; a client
  should read the body's ok / error / navigation.retryable fields rather than expect a status code.
