**LXC Bind Mount Removal**:
- Changed from sed to `pct set -delete` for safer mount removal
- Validates syntax and prevents breaking container configs
- Finds mount points by grepping for pulse-sensor-proxy, extracts mp number
**API Token Parsing** (three-tier fallback):
1. Try `pveum --output-format json` with python3 JSON parsing
2. Fall back to `pvesh get /access/users/pulse-monitor@pam/token` JSON API
3. Last resort: parse table output with improved filtering (handles more Unicode chars)
**Retry Logic**:
- Rename cleanup-request.json to .processing instead of deleting immediately
- Allows retry on failure (processing file persists if script crashes)
- Remove .processing file only on successful completion
- Prevents loops while enabling failure recovery
