# Specification Quality Checklist: Cross-Tenant Compare Preview and Promotion Preflight

**Purpose**: Validate full preparation-package completeness and implementation readiness before the feature moves into the implementation loop  
**Created**: 2026-04-27  
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] Business value and operator outcome stay explicit
- [x] The slice is tightly bounded to compare preview, promotion preflight, and portfolio launch continuity
- [x] Runtime-governance sections are present for an implementation-ready package
- [x] All mandatory sections are completed in `spec.md`, `plan.md`, and `tasks.md`

## Requirement Completeness

- [x] No `[NEEDS CLARIFICATION]` markers remain
- [x] Requirements are testable and unambiguous
- [x] Acceptance scenarios are defined for compare preview, read-only promotion preflight, and launch/return continuity
- [x] Edge cases are identified, including explicit rejection of same-tenant compare, cross-workspace attempts, lost entitlement, ambiguous identity, and stale target evidence
- [x] Scope is clearly bounded away from actual promotion execution, queues, persisted drafts, mapping automation, customer-facing compare, and multi-provider work
- [x] Dependencies, assumptions, risks, and follow-up candidates are identified

## Feature Readiness

- [x] The first slice is small enough for a bounded implementation loop
- [x] Concrete repo surfaces are named for compare reuse, portfolio launch, audit reuse, and likely new compare support files
- [x] Foundational work stays preparation-only and does not imply execution scope or new persistence
- [x] The tasks are ordered, testable, and grouped by user story
- [x] No unresolved product question blocks implementation once artifact analysis passes

## Governance Readiness

- [x] Workspace and tenant isolation rules are explicit, including `404` for non-members and out-of-scope tenants
- [x] The capability matrix is explicit: page access = `WORKSPACE_BASELINES_VIEW`, preview data = `TENANT_VIEW` on both tenants, preflight execution = `WORKSPACE_BASELINES_MANAGE`, and manage-denied members see a disabled preflight action with permission guidance
- [x] Promotion remains preflight-only, with no write execution, queue, or `OperationRun`
- [x] Audit remains bounded to promotion-preflight entry points with no new compare/promotion persistence truth
- [x] Livewire v4 and Filament v5 compliance, unchanged provider registration in `bootstrap/providers.php`, no new global-search resource, and no new asset strategy are explicit in the package

## Test Governance Review

- [x] Lane fit stays in focused `Unit` plus `Feature` validation only
- [x] Fixture and helper growth stays local to compare preview, preflight classification, and launch-context coverage
- [x] No browser, heavy-governance, or queue family is introduced implicitly
- [x] Minimal validation commands are explicit in the plan
- [x] The active feature PR close-out entry remains `Guardrail`

## Review Outcome

- [x] Review outcome class: `keep`
- [x] Workflow outcome: `keep`
- [x] Next command readiness: implementation prep is ready once artifact analysis is clear

## Notes

- This checklist validates the preparation package only: `spec.md`, `plan.md`, `tasks.md`, and this checklist artifact. It does not claim that runtime code or a promotion workflow already exists.
- The active slice stops before any target mutation, any queued execution, any persisted draft or compare snapshot, and any broader mapping automation.
- No new globally searchable resource is introduced, no new asset registration is expected, and deployment behavior remains unchanged unless a later implementation explicitly adds assets.
