  version: 1.0.0
  x-generated: '2026-09-04'
  x-method: generated
  x-source: API Evangelist enrichment pipeline — records this repo's own derived and searched artifacts
    against the provider's unmodified specification.
  x-note: 'Adds only API Evangelist annotations: cross-references to the artifacts in this repo, the runtime
    conditions the provider documents in prose but never declares in the contract (429, 504, 403-on-auth-failure),
    and the derived x-agentic-access classification from agentic-access/astronomy-api-agentic-access.yml.
    The provider''s specification is never mutated.'

    x-runtime-notes:
      rate-limit: HTTP 429 is enforced on IP and overall consumption. No RateLimit-* or Retry-After header
        is served; the provider says only to retry "after some time". See rate-limits/astronomy-api-rate-limits.yml.
      timeout: HTTP 504 is a documented condition on the studio endpoints and the provider states an identical
        retry succeeds.
      auth-failure-status: v2 answers a bad credential with 403, not 401.
      error-shape: v2 returns raw JSON-Schema validator output under `errors[]` with no stable code. See
        errors/astronomy-api-problem-types.yml.
