 ### gRPC-Web API layer
 
-Backend communication uses ConnectRPC (gRPC-Web). Generated protobuf code lives in `src/gen/` — **gitignored**, produced at build time by `protoc` from `proto/yoresee_doc/v1/yoresee_doc.proto` (sibling repo directory). The production Dockerfile runs codegen before `npm run build`.
+Backend communication uses ConnectRPC (gRPC-Web). Generated protobuf code comes from the npm package `@yoresee-doc/sdk-node` (ESM/Connect build), pinned to tag `v0.1.0` in `package.json` (`git+https://git.yoresee.cc/YoreseeDoc/yoresee_doc_sdk_node.git#v0.1.0`). No local codegen required.
 
 - `src/services/grpc_client.js` — transport, client instances, `unaryCall` wrapper, `messages` re-export
 - `src/services/api/*.js` — domain API functions that wrap `unaryCall` with protobuf request/response mappers
