Production Work Units

Read ../../references/PRODUCTION_WORK_UNITS.md.

1. Start from the approved creative-production spec or current project plan.
2. Prefer complete creative/production slices, not one horizontal unit per document type or department.
3. Give every unit a UNIT-### ID and explicit blocker edges.
4. Make each unit independently reviewable or verifiable.
5. Include concrete acceptance criteria and the validator/QC/human gate that proves them.
6. Write both 00_project/work_units.json and 00_project/work_units.md.
7. Use scripts/work_units.py validate and frontier before execution.
8. Do not silently start blocked units.

Use the Pi pipeline Todo for execution progress. Work units describe production dependency; the Todo describes the currently running process.
