/claim #12

Summary

• Adds collab-embargo-release-guard/, a focused issue #12 slice for final journal/preprint release safety in a live collaborative research editor.
• Blocks release packets that contain active embargo artifacts, unredacted double-blind identity fields, restricted evidence, private collaboration threads, stale approved section versions, or invalid release clocks.
• Emits deterministic JSON packets, a Markdown reviewer report, an SVG summary, and an MP4 walkthrough using synthetic local data only.

Non-overlap

This does not implement the already-submitted broad editor, operation replay, offline conflict, notebook workbench, kernel lease, reference formatting, authorship governance, freeze/recovery, discussion sidebar, autosave, round-trip fidelity, review decision, task dependency, figure/equation anchors, presence privacy, accessibility, or evidence-binding slices. It focuses on the external release boundary for embargo and blinded-review safety.
