Immutable API authority

Publish contract metadata only after parity evidence is locked.

This authority records a named OpenAPI 3.1 contract version, declared client targets, compatibility intent, concurrency guards, and API/UI/CLI parity evidence.

Canonical contract pipelineGenerated clients verified

Live source of truth

The tenant-authorized OpenAPI 3.1 route is exported from the running service, checked for incompatible changes, and used to generate the dashboard TypeScript client and the compiled C# SDK.

Immutable publication records below still capture reviewed intent and parity evidence. Client generation and compatibility enforcement run from the canonical live document, independently of those records.

Declared client targets and parity lifecycle evidence remain empty until a tenant-visible contract UUID is selected.

Guarded publication

Lock metadata and parity preconditions before publishing.

Preview is read-only. If tenant concurrency is omitted, the client discovers it and immediately re-previews the complete guarded payload.

Caller-supplied parity evidence

These rows and identifiers are proof supplied by the caller. The authority validates shape and concurrency; it does not discover contract/parity baselines, generate clients, or compute a diff.

Before publishing: this creates an immutable metadata record immediately. It does not upload an OpenAPI document, generate or deliver SDKs, run a generation job, identify consumers, schedule deprecations, or calculate compatibility.
