+# Implementation: Remove File System Watcher
+
+## Summary
+Removed the half-implemented `refresh.py` file system watcher module and updated the dashboard README to reflect the actual client-side polling refresh mechanism.
+
+## Files Changed
+- `automaton/dashboard/core/refresh.py` — deleted
+- `automaton/dashboard/README.md` — removed watcher from architecture diagram, fixed tree formatting
+
+## Verification
+- `automaton/dashboard/core/refresh.py` no longer exists.
+- `python -m automaton.dashboard` still starts and refreshes via JS polling.
+- `python -m pytest tests/` still passes.
+
+## Decisions
+- The dashboard uses client-side polling (`setInterval`) for auto-refresh.
+- No replacement watcher was implemented.
