+# Recovery Reference
+
+Use this reference after bootstrap when the synced project needs inspection, conflict recovery, or server-side continuation.
+
+## Inspect Status
+
+Run these from the migrated project root:
+
+```bash
+cat .codex-sync/manifest.json
+cat .codex-sync/runtime/status.json
+cat .codex-sync/runtime/last-error.log
+git status -sb
+```
+
+If `status.json` says `blocked`, the last sync hit a rebase or merge conflict and automatic sync has paused itself.
+
+## Resolve A Conflict
+
+1. Open the project and inspect `git status`.
+2. Resolve the conflict or decide which side to keep.
+3. Finish the git operation or abort it explicitly.
+4. Remove `.codex-sync/runtime/blocked`.
+5. Re-run `.codex-sync/bin/sync-once.sh`.
+
+## Re-run Sync Manually
+
+```bash
+./.codex-sync/bin/sync-once.sh --project-dir "$PWD"
+```
+
+Pass `--host-label local-manual` or `--host-label remote-manual` when you want the autosave commit to identify where it was triggered.
+
+## Continue The Task On The Server
+
+```bash
+cd /root/continue/<project>
+./.codex-sync/bin/continue-task.sh
+```
+
+That command starts Codex with a prompt that tells it to read `.codex-sync/handoff.md`, inspect sync status, and continue work from the server checkout.
+
+## Service Control
+
+The exact service names are written into `.codex-sync/manifest.json` and `.codex-sync/README.md`.
+
+Local macOS:
+
+```bash
+launchctl print "gui/$(id -u)/<launchd-label>"
+launchctl kickstart -k "gui/$(id -u)/<launchd-label>"
+```
+
+Remote Linux:
+
+```bash
+systemctl status <systemd-service> <systemd-timer>
+systemctl restart <systemd-service>
+systemctl restart <systemd-timer>
+```
