  policy_published: false
  note: >-
    One coherent release number across seven surfaces, which is rarer than it should be. No versioning policy
    page states what a v2 path would mean or how long v1 is supported. The spec's last-modified header was
    Wed, 16 Sep 2026 17:28:27 GMT.
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  deprecated_operations:
  - operation: 'POST /v1/ara/query'
    summary: 'ARA query (legacy, deprecated: use /v1/ara/agent/{agent_id}/profile or /timeline)'
    replacement: ['GET /v1/ara/agent/{agent_id}/profile', 'GET /v1/ara/agent/{agent_id}/timeline']
    sunset: null
  - operation: 'GET /v1/ara/environment/summary'
    summary: 'Deprecated: use GET /v1/ara/environment instead. Returns identical data.'
    replacement: ['GET /v1/ara/environment']
    sunset: null
  documented_retirements:
  - what: indefinite retention subscription
    evidence: 'Routes /v1/retention/indefinite/* remain in the contract but return 503 FeatureUnavailable; GET /v1/pricing/current says indefinite_available false. Changelog 2026-08-25 "A subscription that could not be bought".'
    note: Feature-flagged off, not deprecated; availability "can change without any change to this specification".
  - what: x402 v1 header X-PAYMENT
    evidence: 'AGENTS.md: "X-PAYMENT is the x402 v1 header name and is not accepted."'
  note: >-
    Two operations carry deprecated: true with a named replacement but no removal date, and no
    Deprecation/Sunset headers are declared. No deprecation policy page exists, so no Deprecation pointer is
    emitted.
status_page:
  url: null
  probed:
  - {url: 'https://decision-anchor.com/status', status: 404}
  - {url: 'https://status.decision-anchor.com/', status: 'DNS does not resolve'}

    observed: '{"status":"ok","version":"1.3.42","uptime_seconds":29382,"dac_ur_batch":{"buffered":0,"consecutive_failures":0,"blocked":false,"last_failure_at":null}}'
    note: A liveness endpoint with an uptime counter and one subsystem's health — not an incident history or an uptime commitment, so no StatusPage pointer is emitted. uptime_seconds 29,382 (~8 h) at probe time indicates a recent process restart.
sla:
  published: false
  note: No uptime target or support SLA anywhere found. The only time commitments are operational windows inside the contract (30-minute payment window on externally paid DDs; ASA subscription 90-day period with 7 grace days).

  note: A prose defect log ("a record of the environment itself — what was found to be wrong and how it was corrected") rather than a release-notes list; entries are dated but not tied to release numbers.
