+# PAUSED 2026-05-29: Phase 12 (mobile Tauri) is on hold and the mobile shell
+# does not currently compile, so this cargo-check was failing on every push to
+# main and every mobile/workflow-touching PR — pure wasted CI. Reduced to
+# manual-only (workflow_dispatch). RE-ENABLE the push/pull_request triggers
+# below when mobile work resumes (see docs/phase-12-pause-state.md).
