- Remove iCloud duplicate files (test_db 2.py, src/db 2.py)
- Fix metrics expression fallback to top-level field in transformer + webapp
- Fix sync_data.sh rsync exception pattern for $SSH_HOST variable
- Fix deploy_guard cp regex to skip shell variable expansions
- Update sudoers-deploy with missing root:data-ops rules
- Update CRITICAL_DIRS ownership expectations to match deploy.sh reality

913 tests passing, 0 failures.
