# Preparation Review Checklist: Decision-Based Governance Inbox v1

**Purpose**: Validate the governance inbox preparation package against the repo's guardrail, disclosure, shared-family, and close-out workflow before implementation  
**Created**: 2026-04-28  
**Feature**: [spec.md](../spec.md)

## Applicability And Low-Impact Gate

- [x] CHK001 The package explicitly treats this as an operator-facing workspace decision surface, so the low-impact `N/A` path is not used.
- [x] CHK002 The spec, plan, and tasks carry the same native/shared-primitives-first classification, shared-family relevance, state ownership, and close-out targeting without inventing second wording.

## Native, Shared-Family, And State Ownership

- [x] CHK003 The inbox remains a native Filament page that reuses existing source surfaces instead of introducing a fake-native task console or separate monitoring shell.
- [x] CHK004 Shared families remain shared: findings, operations, alerts, and review follow-up stay on their existing source pages, while the new page stays a routing and decision layer.
- [x] CHK005 Page and URL-query state owners are named once, and the package does not collapse them into new persisted workflow state.
- [x] CHK006 The likely next operator action and primary inspect/open model stay coherent: each section has one dominant source CTA and the page owns no mutation lane.

## Shared Pattern Reuse

- [x] CHK007 Cross-cutting interaction classes are explicit, and the shared reuse path is named once through `CanonicalNavigationContext`, `RelatedNavigationResolver`, `OperateHubShell`, `OperationRunLinks`, `BadgeRenderer`, `UiEnforcement`, and the existing source pages.
- [x] CHK008 The package extends existing shared paths where they are sufficient, and any fallback to a bounded `Support/GovernanceInbox/` seam is explicitly constrained as a last resort rather than a new default abstraction.
- [x] CHK009 The package does not create a parallel operator UX language for claim, acknowledge, stale-run handling, or review follow-up; it routes into the current source-family vocabulary.

## OperationRun Start UX Contract

- [x] CHK019 The package explicitly states that the inbox only deep-links into existing `OperationRun` detail and does not start, queue, or complete runs.
- [x] CHK020 Canonical operation URLs are delegated to the shared `OperationRunLinks` path rather than recomposed locally on the inbox page.
- [x] CHK021 No queued DB-notification or terminal-notification behavior is added because the slice is read-only.
- [x] CHK022 No OperationRun exception is required; if implementation later adds local run-start or blocked-run messaging, that would be out-of-scope drift.

## Provider Boundary And Vocabulary

- [x] CHK010 The package keeps provider-specific semantics behind existing normalized governance, alerting, and review seams and does not spread provider language into a new platform-core contract.
- [x] CHK011 No retained provider-specific shared boundary is introduced; the slice stays inside existing workspace, tenant, operations, findings, alerts, and review vocabulary.

## Signals, Exceptions, And Test Depth

- [x] CHK012 The triggered repository signal is explicitly handled as `review-mandatory`, with no hidden hard-stop drift accepted into the package.
- [x] CHK013 No bounded exception is required in the preparation package; if implementation proves a bounded assembly helper is necessary, it must be recorded in the active feature close-out entry.
- [x] CHK014 The required surface test profile is explicit: `global-context-shell`.
- [x] CHK015 The chosen lane mix is the narrowest honest proof for this slice: focused `Unit` plus `Feature` coverage only.

## Audience-Aware Disclosure And Decision Hierarchy

- [x] CHK023 Default-visible content stays decision-first and clearly separated from deeper diagnostics and support or raw evidence.
- [x] CHK024 The inbox default path does not expose raw JSON, copied payloads, provider diagnostics, or other debug semantics by default.
- [x] CHK025 Exactly one dominant next action remains primary per section or entry: open the relevant existing source surface.
- [x] CHK026 Duplicate visible blocker, status, or next-action summaries are avoided by keeping proof and detailed reasoning on the source pages.
- [x] CHK027 Support/raw sections remain off the inbox page entirely, and the page stays within Filament visual language, progressive disclosure, and calm read-only presentation.

## Review Outcome

- [x] CHK016 Review outcome class: `acceptable-special-case`
- [x] CHK017 Workflow outcome: `keep`
- [x] CHK018 The final note location is explicit: the active feature PR close-out entry `Guardrail / Exception / Smoke Coverage` records any bounded assembly-seam exception and the final proof outcome.

## Notes

- This checklist validates the preparation package only: `spec.md`, `plan.md`, `tasks.md`, and supporting design artifacts. It does not claim application code exists.
- The slice remains bounded to one read-only workspace decision surface in the current admin plane. No new task engine, no new attention state, and no local mutation lane are approved by this package.
- If implementation later proves that a bounded `Support/GovernanceInbox/` seam is necessary, that must stay derived and page-scoped rather than becoming a generalized workflow framework.

## Guardrail / Exception / Smoke Coverage

- Implementation status: complete for the bounded v1 slice.
- Guardrail result: PASS. The implemented page stayed native, read-only, shared-primitives-first, and inside the existing admin plane without adding a new task engine, persisted inbox truth, or local mutation lane.
- Bounded exception result: `document-in-feature`. `apps/platform/app/Support/GovernanceInbox/GovernanceInboxSectionBuilder.php` was added as the smallest readable cross-family assembly seam.
- Validation result: the focused unit and feature proof command passed with `10 passed (53 assertions)`, and dirty-only Pint passed.
- Smoke result: PASS. A manual integrated-browser run on `/admin/governance/inbox` verified route load, canonical operations drill-through with `nav` context, and successful return to the inbox.
