Molecules are the LEDGER, not a task checklist. Each step closure
is a timestamped CV entry. Batch-closing corrupts the timeline.
Added explicit warnings to:
- molecules.md (first best practice)
- polecat-CLAUDE.md (new 🚨 section)
The discipline: mark in_progress BEFORE starting, closed IMMEDIATELY
after completing. Never batch-close at the end.
