/claim #12

Summary

• Add collab-review-decision-ledger, a focused real-time collaborative research editor slice for final freeze/publish decisions.
• Audit blocking comments, open suggestions, stale notebook outputs, required role approvals, section lock mode, sidebar decision records, and restore-ready snapshots.
• Emit per-section release decisions, document priority actions, stable crdl_ decision digests, JSON/SVG demo outputs, and the required short H.264 MP4 demo artifact.

Non-overlap

This is not another broad editor foundation, operation replay, offline conflict rebasing, notebook workbench, reference formatting, authorship governance, lock/checkpoint recovery, freeze lane, figure/table review lane, discussion-sidebar audit, autosave recovery, or round-trip fidelity checker. It focuses on final collaborative review decisions before freeze/publish.
