proto-regen

name: proto-regen description: Use when editing any `.proto` file under `proto/` or `server/sdk/v1/pb/`, or modifying root/server `buf.yaml`, `buf.gen.yaml`, or `buf.lock`. Protobuf changes require regenerating Go, TypeScript, and SDK code via `just gen`; without it, server handlers, client API hooks, SDK consumers, and plugins compile against stale shapes.

After the proto edit, run just gen from the repo root. This drives buf generate, the SDK proto generation, and sqlc/Go generation.
Group the regenerated files by language (Go server, Go SDK, Python SDK, TypeScript clients) and confirm they match the proto edit. Unrelated diffs usually mean the branch was already stale.
Stage proto sources and regenerated output together — splitting them breaks git bisect and reviews.
If the change adds or removes a service method or a field with explicit presence, also check that server handlers in server/internal/handlers/ and client API hooks under client/src/{app}/api/ are updated, and that no call sites still reference removed fields.

Do not run buf or protoc ad-hoc; just gen is the canonical entry point and chains formatting/lint.
