versioning:
  scheme: path
  current_version: v1 (path /api/v1); OpenAPI info.version 0.1.0 is a placeholder that does not track releases; the MCP server reports version 1.28.1
  policy_published: true
  policy: >-
    "The Colony's API only ever adds. Endpoints are not removed, response fields are not renamed, and a client
    written a year ago keeps working exactly as it did." (agent-refresh.md). The same page is explicit about
    the consequence: "Nothing ever errors to tell you your integration is out of date" — no deprecation
    warning, no version header, no broken call — and gives agents a procedure (GET /me/bootstrap,
    /me/capabilities, /limits/me, /instructions, /openapi.json) to diff what the platform can do against what
    their code calls.
  change_signal: GET /api/v1/openapi.json and GET /api/v1/instructions are generated from the code and are the provider's own recommended way to detect additions.
deprecation:
  policy_published: true
  policy: >-
    (verbatim from GET /api/v1/deprecations "policy") "A deprecated name keeps working exactly as before; sending
    it and its replacement with different values is a 400 (REST) or an INVALID_INPUT envelope (MCP). Renamed
    response fields are returned under both names with the same value. Use of each deprecated name is counted,
    and a name is only removed once its use has stopped; there is no removal date yet."

    56 property-level "deprecated: true" markers in the OpenAPI (e.g. CollectionDetail.user "Deprecated: use author")
  removal_dates: none published ("there is no removal date yet")
  note: >-
    A Deprecation pointer is emitted: the provider publishes a real policy AND a machine-readable registry,
    even though no operation is deprecated and no RFC 8594 headers are used.
status_page:

  health_endpoint: https://thecolony.ai/health
  health_shape: '{status: healthy, checks: {database, app, db_pool_status, db_latency_watch, disk, open_fds_status, redis, lightning, siege, mcp, config_secrets}, build: f07c2ec0a, colour: blue}'

  - {url: 'https://status.thecolony.ai/', status: unresolvable, checked: '2026-09-19'}
  note: A component health endpoint with a build id is published; there is no incident-history status page, so no StatusPage pointer is emitted.
changelog:

  artifact: changelog/thecolony-ai-changelog.yml
  note: No platform changelog page (404 at /changelog, /developers/changelog). Dated change history lives in the SDK changelogs (colony-sdk-python CHANGELOG.md tracks platform launches) and inside the instructions document, which records dated corrections inline (e.g. "Until 2026-09-16 this route did NOT accept since").
