  Versioning, deprecation posture, changelog and status surface for the Millimetric Analytics
  API. Re-checked 2026-08-13.
versioning:
  scheme: uri-path
  current: v1
  policy: >-
    /v1/* is stable. Additive changes (new fields on existing endpoints, new endpoints)
    happen in place. Breaking changes will appear under /v2/*.
  docs: https://docs.millimetric.ai/api-reference/overview.md
deprecation:
  policy_url: null
  sunset_header: false
  note: No formal deprecation policy or RFC 8594 Sunset/Deprecation header support documented.
sla:
  url: null
  uptime_target: null
changelog:
  published: false
  advertised_url: https://docs.millimetric.ai/changelog
  probe:
    url: https://docs.millimetric.ai/changelog
    http_status: 404
    checked: '2026-08-13'
  soft_404:
    url: https://docs.millimetric.ai/changelog.md
    http_status: 200
    body: '# Page Not Found — The URL `changelog` does not exist.'
    note: >-
      The .md variant answers HTTP 200 with a GitBook "Page Not Found" body. It is a soft-404,
      not a changelog — recorded so a later pass does not credit it as a document.
  note: >-
    The marketing site footer links a Changelog under Product (https://docs.millimetric.ai/changelog)
    but the page does not exist, and no changelog appears in the docs llms.txt index. No dated
    release history is published anywhere on the provider's surface, so no changelog/ artifact and
    no ChangeLog pointer are emitted.
status_page: https://status.millimetric.ai
status_page_note: >-
  Advertised on the marketing site and docs. Live probes on 2026-07-20 and again on 2026-08-13
  both returned HTTP 525 (Cloudflare origin TLS handshake failure) — the subdomain is provisioned
  but has never served a valid response in either probe, so the advertised status page is not
  actually reachable.

roadmap_items:
  - Server-side event deduplication (idempotency enforcement).
  - Structured audit row on /v1/forget.
  - Durable Object token bucket for multi-tenant rate-limit fairness.
