+ * The bridge daemon resolves same-bundle harness instances by shelling out to `ps`. Unit tests that
+ * assert the default app-activate AppleScript path must force the resolver to return `null`,
+ * otherwise a developer machine with Claude.app already running can take the PID-targeted branch
+ * while CI takes the activate branch.
