+# Collaborative Review Freeze Lane
+
+This submission targets [SCIBASE issue #12](https://github.com/SCIBASE-AI/SCIBASE.AI/issues/12) with a focused real-time collaborative editor module.
+
+It models the review freeze workflow a scientific manuscript editor needs before submission: direct edits pause, reviewer comments and suggestions remain open, notebook outputs must be fresh, blocking tasks must be cleared, and a version snapshot can be exported for history or audit trails.
+
+## What It Adds
+
+- Section-level freeze windows for manuscript review and submission prep.
+- Direct edit protection while still allowing comments, suggestions, and task updates.
+- Notebook execution freshness checks before a frozen section can be released.
+- Blocking reviewer comments and tasks that gate unfreezing.
+- Stable version snapshots for autosave and history timelines.
+
+## Demo
+
+```powershell
+node collab-review-freeze-lane/test.js
+node collab-review-freeze-lane/demo.js
+```
+
+`demo.mp4` is the reviewer-facing video artifact for the bounty submission. It walks through the problem, implementation, acceptance path, and command validation in 8.4 seconds. `demo.svg` shows the freeze lane from active edits to reviewer clearance and version snapshot export.
+
+See `acceptance-notes.md` for the payout-gate evidence checklist.

+# Acceptance Notes
+
+This is a focused implementation for SCIBASE issue #12, not a generic AI-generated content drop. The module stays small so reviewers can inspect the review-freeze workflow, validation rules, and version snapshot behavior without pulling in a full editor stack.
+
+## What Changed
+
+- Added section-level freeze windows for manuscript review and submission prep.
+- Added operation handling that blocks direct edits while preserving comments, suggestions, tasks, and notebook checks.
+- Added clearance logic for blocking comments, open tasks, unresolved suggestions, and stale notebook outputs.
+- Added stable version snapshot export for autosave, history, and audit trails.
+- Added focused dependency-free tests and demo data.
+
+## Video Demo
+
+- `demo.mp4` shows the problem, implementation, acceptance behavior, and validation command.
+- `demo.svg` provides a static workflow diagram.
+
+## Validation
+
+Run from the repository root:
+
+```powershell
+node collab-review-freeze-lane/test.js
+node collab-review-freeze-lane/demo.js
+```
+
+Expected result: the test prints `collab-review-freeze-lane tests passed`, and the demo prints a freeze clearance packet showing blockers before and after review cleanup.
+
+## Integration Notes
+
+The module is dependency-free and uses plain document state objects so it can be adapted into a collaborative editor service. The next integration step is mapping these operations to SCIBASE editor events and persistence.
