name: Sayduck Platform Lifecycle
summary: >-
  Sayduck tracks platform releases publicly on GitHub and marks superseded
  developer surfaces as "[Legacy]" in its help center. No public status page or
  formal HTTP deprecation-header (RFC 8594) program was found — the integration
  surface is a browser Web Component rather than a versioned HTTP API.
versioning:
  scheme: Incrementing platform release numbers (e.g. v2.12) with additional repo tags (v4.4.9).
  changelog: https://github.com/Sayduck/sayduck-platform-release/releases
  strategy: >-
    Single continuously-updated hosted viewer/platform; no per-request API
    version negotiation. Older embed/API surfaces remain documented as legacy.
deprecation:
  policy_page: null
  signal: Help-center articles prefixed "[Legacy]" (Legacy 3D Viewer, Legacy Configurator API, Legacy Dynamic 3D Viewer).
