+        For cleanup changes, compare executable behavior against the PR merge
+        base. Check for removed guards, changed return values, weakened compiler
+        flags, and deleted regression tests. A passing APK build alone does not
+        establish behavior preservation. Avoid style-only or comment-coverage
+        requests.

+      instructions: >-
+        Review Android lifecycle, external-display visibility, input cancellation,
+        permissions, threading, and Compose state. For JNI, native, and Rust
+        changes, check ABI compatibility, resource ownership, synchronization,
+        and error paths. Preserve persisted user settings and existing runtime
+        contracts.
+    - path: "tools/**"
+      instructions: >-
+        Check shell quoting, error handling, path and filesystem semantics, and
+        Python helper behavior. Preserve MSI same-file protection and strict
+        compiler checks. Verify downstream patches apply to their pinned sources
+        and retain intended executable behavior, including embedded scripts.
+    - path: ".github/workflows/**"
+      instructions: >-
+        Check job permissions, triggers, merge validation, build variants,
+        signing, artifact paths, and release conditions. Verify checks apply to
+        the current PR head and keep review configuration advisory.
