Add Compare to deployed workflow row menus in fork push/pull settings. Reuse the existing comparison modal for Last Sync → Now, with structured subblock diffs and explicit unavailable states.
Advance the Last Sync baseline only when its destination deployment activates. Keep histories separate by fork and direction, preserve them through operation retention, and handle rollback, unlink, and deleted snapshots without guessing a baseline.
Pin reviewed source versions and commit mapping choices with the sync transaction. Share deployment admission across internal and v2 sync; expose comparison metadata in preview responses and the generated CLI contract.

Testing
Full repository suite on Node 24 with four workers: 349 script tests, 34,650 app tests, and all 19 workspace test tasks passed.
27 real PostgreSQL/HTTP/CLI integration tests; 8 running-app HTTP/CLI/MCP comparison checks; 6 internal fork HTTP checks. Activation, rollback, stale-source, exact-snapshot, and unlink regressions fail when their guards are independently removed.
Browser verified Pull and Push menus, readable header-table changes, unavailable/new-workflow states, and an actual push followed by an identical Last Sync → Now comparison.
Lint, 58 audits, all workspace type checks, standard generators, fresh migration replay, migration safety, and schema-drift checks passed.

[High risk] Adds database schema and fork sync comparison tracking.
The PR appears safe to merge; no outstanding finding or new actionable issue was identified.
Summary
The PR adds exact source-deployment comparisons to fork sync and records the baseline when the destination deployment activates. It also pins source versions during sync, exposes comparison metadata through preview contracts, and covers activation, rollback, retention, and unlink behavior with integration tests. The follow-up changes document the comparison components, adjust deployment-result checks, and add a provenance lookup index.
