 The workspace checks TypeScript adapters, extension code, installer, OMP adapter, and package builds. The architecture gates cover manifest identity, required and optional permission behavior, RPC schemas, forbidden legacy surface, and Rust IPC framing. They do not operate a real signed-in browser.
 
+## Pull request routing
+
+Pull requests that change only `README.md`, `CHANGELOG.md`, `LICENSE`, documentation files ending in `.md`, `.rst`, or `.txt` under `docs/`, or a top-level `.github/*.md` file use the lightweight CI lane. The classifier still scans added public text for credentials, private paths, session identifiers, and private hosts. Source, manifest, workflow, nested GitHub, executable documentation, mixed, empty, or ambiguous changes use the full cross-platform lane.
+
+Branch protection requires the stable `verify` check. The automatic review ruleset requests a fresh review after every push. Before merging, confirm that the latest automated review commit matches the current pull-request head; if the commits differ, request another review. Unresolved review threads remain merge blockers.
