+# relayfile mount-root invariant incident
+
+- timestamp: 20260608T102342Z
+- local root: /home/daytona/workspace/memory/workspace
+- invariant: mount root must always be a directory
+- detected kind: missing
+- reason: local root does not exist
+
+## Recovery
+
+The mount root is gone. Confirm whether the directory was deleted
+by another process (rm -rf, git clean -fdx, sync tool, etc.).
+To recreate a clean mount, pass `--reset-after-clobber` to
+`relayfile mount` (or set `RELAYFILE_RESET_AFTER_CLOBBER=1`).
+The daemon will refuse to start without this acknowledgment.
+
+See `docs/architecture/mount-invariants.md` for the protected
+invariants and the full recovery procedure.
