versioning:
  scheme: uri-path
  current: v3.0
  concurrent:
  - v3.0 — orders, marketplaces, documents, product reports
  - v1.0 — catalogues API, marked [BETA] in every operation summary
  unversioned:
  - /access/get_token
  - /me
  - /rate-limits
  docs: https://docs.lengow.io/#getting-started
  note: >-
    v1.0 is NEWER than v3.0 — the number is a per-service version, not a platform version. Every
    catalogue operation is labelled [BETA] in the published spec, so the newest surface is explicitly
    pre-stable.
beta_surface:
  api: Catalogues (v1.0)
  operations: 10
  marker: '[BETA] prefix on every operation summary in the published OpenAPI'
  stability_commitment: none published
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  deprecated_operations: []
  note: >-
    No deprecation policy, no notice period and no RFC 8594 Sunset/Deprecation header support is
    published, and the OpenAPI marks no operation `deprecated`. What Lengow does publish is a
    deprecation COMMUNICATION channel: the API Release Notes define "Deprecation" and "Removal" as
    change categories and have carried a real removal in the past (category_name, 2017-12-18). That is a
    notification habit, not a policy, so no Deprecation pointer is emitted in apis.yml.
  evidence:
  - url: https://docs.lengow.io/#api-release-notes
    finding: 'Deprecation and Removal are declared change categories; no timeline or notice-period commitment'
  - source: openapi/lengow-channel-execution-openapi.yml
    finding: 0 occurrences of "deprecated", "sunset"
status_page:
  url: null
  note: >-
    No status page found. status.lengow.com does not resolve (NXDOMAIN), status.lengow.io times out, and
    https://lengow.statuspage.io/ answers 302 to https://www.statuspage.io/ — an unclaimed Statuspage
    subdomain, not an operating status page. No StatusPage pointer is emitted.
  evidence:
  - url: https://status.lengow.com/
