notes: >-
  Tvarka documents the rate-limit SIGNAL (429 + Retry-After in seconds + a stable rate_limited error
  code, declared on every metered operation in the OpenAPI) but publishes no numeric request quota,
  burst allowance or window. Per-provider throughput is set during onboarding. No quota numbers are
  recorded here because none are published - this is an observed absence, not a gap in the harvest.
