# Preparation Review Checklist: Governance Decision Surface Convergence v1

**Purpose**: Verify that the preparation package is repo-grounded, narrowly scoped, and ready for a later implementation loop.
**Created**: 2026-04-29
**Review outcome class**: Workflow Compression
**Workflow outcome**: approve for implementation
**Test-governance outcome**: keep

## Candidate Selection

- [x] CHK001 The selected slice is anchored to `docs/product/roadmap.md` (`Decision-Based Operating Foundations`) and the open-gap truth in `docs/product/implementation-ledger.md`.
- [x] CHK002 Already-specced candidates such as Spec 043, Spec 249, Spec 250, Spec 251, Spec 252, Spec 253, Spec 254, Spec 255, and Spec 256 are explicitly excluded from reopening.
- [x] CHK003 The package chooses the smallest repo-grounded slice: extend the existing governance inbox and specialist pages instead of inventing a new shell or workflow engine.

## Scope And Truth

- [x] CHK004 The spec, plan, and tasks all state that no new persistence, inbox-item truth, queue state, or mutation lane is introduced.
- [x] CHK005 The governance inbox remains the canonical workspace decision home, while specialist queues and the customer review workspace remain secondary-context surfaces.
- [x] CHK006 The finding-exceptions lane and review-consumption handoff are described as derived from existing repo truth rather than a new abstraction layer.

## UX And Authorization

- [x] CHK007 The package makes one dominant next action explicit for the governance home, preserves one dominant default action on each specialist surface, and keeps specialist pages from duplicating the workspace-level summary.
- [x] CHK008 `404` vs `403` semantics are explicit for workspace membership, tenant scope, and no-visible-family cases.
- [x] CHK009 Hidden tenants and hidden families are omitted from counts, labels, previews, and empty-state hints.

## Test Governance

- [x] CHK010 Planned proof stays in focused `Unit` plus `Feature` lanes only, with explicit validation commands.
- [x] CHK011 The tasks include explicit coverage for family assembly, arrival/return continuity, latest-published-review preference versus workspace fallback, duplicate-truth prevention, and read-only review integrity on the specialist pages.
- [x] CHK012 The checklist records the active review outcome class and workflow outcome instead of leaving readiness implicit.

## Readiness Outcome

- [x] CHK013 The package is ready for implementation only if analysis confirms that the scope remains bounded to existing governance, findings, monitoring, and review seams and that `CustomerReviewWorkspace` stays read-only.
- [x] CHK014 The package explicitly preserves the no-new-Graph-call, no-queue, no-`OperationRun`, and no-new-audit-stream constraints for this slice.
- [x] CHK015 Any broader dashboard-entry, cross-tenant, or workflow-engine follow-up is listed separately rather than hidden inside this slice.
