  Replaces the 2026-05-04 bulk-sweep scaffold, which asserted invented per-key values (10
  requests/minute free tier, X-RateLimit-* headers) that Google does not publish. Every figure
  below is quoted from the provider's own Quotas and limits page, read 2026-09-12. Cloud
  Logging quota is per Google Cloud PROJECT, not per API key.

description: >-
  Published Cloud Logging API v2 quotas and entry-size limits, and the (absent) runtime
  rate-limit signalling an agent can observe on a response.
headers:
  limit: null
  remaining: null
  reset: null
  retryAfter: null
  policy: null
headers_note: >-
  Cloud Logging publishes NO rate-limit response headers. There is no X-RateLimit-*,
  RateLimit-* or Retry-After to read. An agent learns it is throttled only from the error body
  — HTTP 429 with "status": "RESOURCE_EXHAUSTED" — and observes headroom out-of-band through
  Cloud Monitoring quota metrics. This is a real gap for runtime agents and is recorded as an
  absence, not guessed.

      Also applies to billing accounts, folders and organizations, and is NOT hierarchical.
      This is the binding constraint on any read-heavy or agent-driven query workload.
