# Preparation Review Checklist: Workspace, Tenant & Managed Object Lifecycle Governance v1

**Purpose**: Verify that the lifecycle-governance package stays repo-grounded, taxonomy-first, and non-runtime.
**Created**: 2026-05-01
**Review outcome class**: Core Enterprise
**Workflow outcome**: approve for implementation on the standards-and-contract path only
**Test-governance outcome**: keep

## Candidate Selection

- [x] CHK001 The package records that this candidate was promoted only by explicit product decision and not by automatic next-best-prep selection.
- [x] CHK002 Already-prepared slices such as Specs 143, 251, 261, and 091 are treated as dependencies or boundaries, not reopened implementation scope.
- [x] CHK003 The selected slice matches the deferred candidate's documented smallest useful v1: taxonomy, naming, transition rules, retention boundaries, and follow-up guardrails only.

## Scope And Truth

- [x] CHK004 The package defines exactly six lifecycle dimensions and maps each to current repo-real sources.
- [x] CHK005 The package explicitly distinguishes current repo-real values from reserved follow-up values.
- [x] CHK006 The package answers the deferred candidate's mandatory meaning questions without adding runtime behavior.
- [x] CHK007 The package forbids proxy use across lifecycle dimensions.

## Safety And Governance

- [x] CHK008 The transition-governance matrix makes confirmation, audit, OperationRun, and export/retention prerequisites explicit.
- [x] CHK009 Provider-specific semantics remain provider-owned, while shared lifecycle labels stay platform-neutral.
- [x] CHK010 No runtime deletion, purge, panel, provider, asset, or lifecycle-engine work appears in the package.

## Test Governance

- [x] CHK011 The package records explicit validation commands and a test-governance outcome even though it is docs-only.
- [x] CHK012 The package leaves no hidden runtime proving requirement or browser/heavy-governance lane expansion.

## Readiness Outcome

- [x] CHK013 Every adjacent concern from the deferred candidate is listed as a named follow-up slice rather than hidden scope.
- [x] CHK014 The standards directory is named as the intended implementation landing zone.
- [x] CHK015 The package is ready for a later implementation loop only if implementation remains on the standards and contract path.

## Implementation Close-Out Outcome

- [x] CHK016 The standards document now exists at `docs/product/standards/lifecycle-governance.md`.
- [x] CHK017 The standards index references the lifecycle-governance standard.
- [x] CHK018 The contract, data model, quickstart, and standard remain aligned on six dimensions, transition ownership, execution path, and follow-up boundaries.
- [x] CHK019 The implementation introduced no runtime behavior, product persistence, Filament surface, provider behavior, asset, queue, or browser-visible flow.
