description: >-
  Lifecycle posture for SiFive's public developer surface. SiFive publishes no API
  versioning policy, no deprecation policy, no SLA and no status page — its release cadence
  is expressed through dated software releases in the sifive GitHub organization and
  through GitHub repository archival rather than through any published lifecycle document.
versioning:
  scheme: dated-release
  api_versioning: none
  evidence: >-
    The SCS OAuth endpoints are unversioned (/o/authorize/, /o/token/). Software releases
    use a YYYY.MM date-train tag — e.g. sifive/freedom-tools v2020.12.0 "December 2020 Tools
    Release".
  docs: null
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  evidence: >-
    No deprecation or sunset policy is published anywhere on sifive.com. Deprecation is
    signalled only in-band on GitHub: sifive/freedom-e-sdk is archived and its description
    reads "Open Source Software for Developing on the Freedom E Platform - Deprecated".
  note: >-
    No `type: Deprecation` pointer is wired in apis.yml — a repository description is not a
    deprecation policy.
sla:
  url: null
  uptime_target: null
  published: false
status_page:
  url: null
  published: false
  evidence:
  - {url: 'https://status.sifive.com', status: 000, note: 'does not resolve'}
  - {url: 'https://www.sifive.com/status', status: 404}
  - url: 'https://sifive.statuspage.io'
    status: 200
    note: >-
      SOFT 404 — not a SiFive status page. The body is Atlassian's Statuspage marketing
      page, byte-comparable to a control request for a deliberately nonexistent subdomain
      (https://sifive-not-a-real-page-xyz.statuspage.io, also 200, same body). Recorded so a
      later run does not mistake the 200 for a real status page.
  note: >-
    No `type: StatusPage` pointer is wired in apis.yml. SiFive publishes no status page.
