# V13-FE-020 — T10 Version Governance screen template

## Source / Assumption / Unknown / Decision Required

- Source: v60 screen recipe governance requirements and current `VersionGovernancePage.vue` shared screen port.
- Assumption: version comparison, evidence matrix, approval, and rollback are evidence-bearing presentation slots; activation remains human-approved.
- Unknown: approved model/policy API, gate-pack schema, same-dataset/cost definition, rollback contract, and permission mapping.
- Decision Required: Quant/Risk/QA approval before wiring activation or rollback commands.

## Implemented

- Preserves version metadata and governance slots.
- Suppresses comparison/evidence/approval/rollback/footer content in blocked or terminal states.
- Keeps retry under the shared boundary; no automatic promotion, rollback, threshold mutation, or order path is added.

## Evidence

- Targeted test: 1 file / 2 tests passed.
- Typecheck and full FE regression evidence must be refreshed after this Slice; visual/AT/Playwright and G4-A evidence remain outstanding.
