Delivery QC

Workflow

1. Read ../../references/RELEASE_DELIVERY.md and the relevant delivery specification.
2. Use scripts/delivery_qc.py to inspect actual files.
3. Treat missing required files, unreadable containers, missing required streams, or specification mismatches as blockers.
4. Treat optional black/freeze detectors as evidence and warnings unless a project rule makes them blocking.
5. Record SHA-256 for every final deliverable.
6. Never infer QC from a successful generation command alone.

Done

Each final media deliverable has an evidence-backed QC report and checksum.
