API types

The generated API contract has three specs: API v1, API v2, and Platform. Their committed outputs are packages/api-types/types/api-v1.d.ts, packages/api-types/types/api-v2.d.ts, and packages/api-types/types/platform.d.ts.

Update types

Make the API/schema change and ensure it is deployed to production before relying on a type PR. Production is the merge-gate source of truth.
Run pnpm api:codegen against a running local API environment. It fetches all three local OpenAPI specs and updates the committed files.
Inspect and commit only the intended generated type changes.
Run pnpm api:verify-types. It fetches the three production OpenAPI specs, regenerates types with the repository tooling, and compares them with the committed files.

Complete the update only when pnpm api:verify-types passes after the production deployment is available.

Interpret verification

A pass means the committed generated declarations match all three production specs at the time of the check.
A mismatch means production and the committed files differ. If the API is not deployed, deploy it and rerun the check. If production is correct, regenerate and review the changed files.
A fetch failure means the production schema endpoint could not be read; fix or retry the endpoint before treating the result as a type mismatch.

Pull requests

The Verify production API types CI job runs when packages/api-types/types/** changes and performs the same production comparison. It is a required merge check. Run the local verifier before requesting review and treat a failed CI verification as production drift that must be resolved.
