 `.proto` sources — the codegen drift class this repo has hit repeatedly (stale client
 descriptors, net48 `CS0246` on unregenerated protos, silently stale Go/Python worker bindings).
+Check 3 sweeps both directions: a vendored copy that drifted from (or has no) canonical proto
+fails, and so does a canonical proto with no vendored copy at all. The second direction matters
+because `clients/rust/build.rs` prefers the canonical directory whenever it exists, so an
+unvendored proto builds fine in-repo and only breaks the standalone crate build a consumer runs
+from the published tarball — drift no in-repo build can surface.
 Check 4 regenerates the Go and Python bindings with their pinned generators (`protoc-gen-go`
 v1.36.11 / `protoc-gen-go-grpc` 1.6.2, `grpcio-tools` 1.80.0) and fails on any diff; a missing
 generator fails the check rather than skipping it. The **primary** guard for the
