The current public contract is v6.6.6 with stable route paths, explicit API lifecycle headers, live status evidence, and a versioned /api/v1 profile, membership, organization-read, developer, and capability-evidence surface.
Policy
Every update, including small fixes and documentation changes, advances exactly one release version; releases cannot skip a valid successor.
The package, worker fingerprint, health metadata, release manifest, changelog, and OpenAPI info version move together.
The release train rolls x.0.9 to x.1.0 and x.9.0 to the next major .0.0 as documented in the repository policy.
Every new release uses the shared update banner and includes detailed release notes dated Month Day, Year without a clock time.
Deprecated behavior must be called out in the changelog and contract before removal.
