# Requirements Checklist: Spec 428 - Exchange/Teams Content-Backed Evidence Promotion

**Purpose**: Validate preparation readiness for the fail-safe/no-op Spec 428 package.
**Created**: 2026-07-04
**Feature**: `specs/428-exchange-teams-content-backed-evidence-promotion/spec.md`

## Candidate And Repo Truth

- [x] User-provided Spec 428 draft was read as the candidate source.
- [x] `docs/product/spec-candidates.md` was checked; the automatic queue is not the candidate source.
- [x] `docs/product/roadmap.md` was checked for roadmap context.
- [x] Existing `specs/` were checked; Spec 428 did not already exist.
- [x] Completed Specs 414, 415, 417, 419, 420, 422, 426, and 427 are read-only context.
- [x] Spec 427 implementation report was checked for final source-contract states.
- [x] Draft prerequisite conflict is documented: no target type reached `contract_verified_pending_capture`.

## Eligibility

- [x] `exchange.transportRule` maps to `transportRule`.
- [x] `exchange.acceptedDomain` maps to `acceptedDomain`.
- [x] `teams.appPermissionPolicy` maps to `appPermissionPolicy`.
- [x] `teams.meetingPolicy` maps to `meetingPolicy`.
- [x] `transportRule` is `contract_blocked_repo_adapter_missing`.
- [x] `acceptedDomain` is `contract_blocked_repo_adapter_missing`.
- [x] `appPermissionPolicy` is `contract_blocked_repo_adapter_missing`.
- [x] `meetingPolicy` is `contract_blocked_repo_adapter_missing`.
- [x] Eligible type count is zero.
- [x] Spec 428 outcome is fail-safe/no-op, not capture promotion.

## Scope Guard

- [x] No source-contract verification is in scope.
- [x] No provider adapter is in scope.
- [x] No Graph endpoint or provider permission change is in scope.
- [x] No runtime provider call is in scope.
- [x] No resource row or evidence row is in scope.
- [x] No OperationRun creation or queue job is in scope.
- [x] No compare/render expansion is in scope.
- [x] No certification, restore, report, Review Pack, PDF, export, or customer output is in scope.
- [x] No UI surface impact is in scope.
- [x] No `tenant_id`, legacy adapter, fallback reader, dual write, or fake evidence path is in scope.

## Product Surface

- [x] UI Surface Impact is checked as `No UI surface impact`.
- [x] Product Surface Impact is `N/A - no rendered product surface changed`.
- [x] Browser proof is `N/A - no rendered UI surface changed`.
- [x] Human Product Sanity is `N/A - no product surface changed`.
- [x] Product Surface exceptions are `none`.

## Spec Readiness

- [x] `spec.md` exists.
- [x] `plan.md` exists.
- [x] `tasks.md` exists.
- [x] The spec has problem, user value, functional requirements, non-goals, acceptance criteria, assumptions, risks, and follow-ups.
- [x] The plan identifies affected repo surfaces as Spec Kit artifacts only and read-only dependency evidence.
- [x] The tasks are ordered, bounded, verifiable, and enforce no runtime changes.
- [x] RBAC, workspace/managed-environment/provider scope, OperationRun, evidence/result truth, and UX no-impact posture are addressed as no-op constraints.
- [x] No open question blocks safe no-op implementation.

## Preparation Analyze Result

- [x] `speckit-analyze` prerequisite check resolves this feature directory.
- [x] Cross-artifact analysis found no critical, high, medium, or low findings requiring artifact changes.
- [x] Functional and non-functional requirements are covered by implementation tasks.
- [x] Constitution alignment issues are none.
- [x] Unmapped implementation tasks are none; preflight, guard, validation, and report tasks support the no-op close-out.
- [x] Residual risk is limited to future source-adapter/evidence-capture work, which must amend or replace this spec before runtime changes.

## Gate Result

- [x] Candidate Selection Gate: PASS WITH CONDITIONS - direct candidate, safe only as fail-safe/no-op.
- [x] Spec Readiness Gate: PASS WITH CONDITIONS - ready for no-op implementation report, not ready for evidence capture.
- [x] Preparation Analyze Gate: PASS - no findings requiring artifact changes.
- [x] Workflow outcome: keep as fail-safe closure; split any future source-adapter or capture promotion work into a new/amended spec.
