# Implementation Report: Spec 423 - Security and Compliance Readiness Pack

## Preflight

- **Active spec**: `specs/423-security-compliance-readiness-pack/`
- **Implementation start**: 2026-06-30 07:07:58 CEST
- **Branch**: `423-security-compliance-readiness-pack`
- **HEAD**: `13d363c8 feat: complete spec 422 exchange teams comparable renderable pack (#489)`
- **Initial dirty state**: untracked active spec directory only.
- **Activated skills**: `spec-kit-implementation-loop`, `pest-testing`, `.agent/workflows/spec-readiness-gate`, `.agent/repo-contracts/workspace-scope-safety`, `.agent/repo-contracts/rbac-action-safety`, `.agent/repo-contracts/evidence-anchor-contract`, `.agent/repo-contracts/product-surface-gate`, `.agent/workflows/filament-livewire-v5-change-loop`, `.agent/repo-contracts/provider-freshness-semantics`, `.agent/temporary-migrations/tcm-cutover-guard`.
- **Hard-gate stop conditions checked**: no unrelated dirty files; no completed-spec rewrite; no new capture/source contract; no live Graph/TCM/provider/HTTP/docs call; no restore/apply/certification/legal/customer output; no new route/navigation/action/table/dashboard; no OperationRun lifecycle change; no `tenant_id` ownership path; no raw payload/default customer proof; no Security/Purview mini-platform.

## Completed-Spec Guardrail

Specs 414, 415, and 417 through 422 were used as read-only dependency context. No files under their spec directories were edited.

## Security and Compliance Registry Rows

| Canonical type | Source aliases | Restore tier | Risk posture | Repo source truth |
| --- | --- | --- | --- | --- |
| `retentionCompliancePolicy` | `retentionPolicy` | `not_restorable` | high | Registry-only Security and Compliance representative row from Spec 419; live capture remains deferred. |
| `labelPolicy` | `sensitivityLabelPolicy` | `not_restorable` | high | Registry-only Security and Compliance representative row from Spec 419; live capture remains deferred. |
| `dlpCompliancePolicy` | `dataLossPreventionPolicy` | `not_restorable` | high | Registry-only row; Spec 420 proves capture blocks as `capture_blocked_missing_contract`. |
| `autoSensitivityLabelPolicy` | `autoLabelingPolicy` | `not_restorable` | high | Registry-only row; no existing bounded content-backed support evidence found in repo. |
| `protectionAlert` | `alertPolicy` | `not_restorable` | high | Registry-only row; no existing bounded content-backed support evidence found in repo. |
| `complianceTag` | `retentionLabel` | `not_restorable` | high | Registry-only row; no existing bounded content-backed support evidence found in repo. |

## Evidence Promotion Matrix

| Canonical type | Decision | Reason |
| --- | --- | --- |
| `retentionCompliancePolicy` | `promote` | Mandatory type; implement typed support for existing or synthetic content-backed Coverage v2 evidence only. No live capture/source contract added. |
| `labelPolicy` | `promote` | Mandatory type; implement typed support for existing or synthetic content-backed Coverage v2 evidence only. No live capture/source contract added. |
| `dlpCompliancePolicy` | `promote` | Mandatory type; implement typed support for existing or synthetic content-backed Coverage v2 evidence only. Spec 420 missing-contract capture blocker remains unchanged. |
| `autoSensitivityLabelPolicy` | `defer_missing_evidence` | Optional type lacks existing bounded content-backed evidence and focused tests in current repo truth. |
| `protectionAlert` | `defer_missing_evidence` | Optional type lacks existing bounded content-backed evidence and would risk sensitive incident-content exposure without a separate proof slice. |
| `complianceTag` | `defer_missing_evidence` | Optional type lacks existing bounded content-backed evidence and focused tests in current repo truth. |

## Implementation Summary

- Added bounded Security/Compliance helpers under `apps/platform/app/Services/TenantConfiguration/`:
  - `SecurityComplianceComparablePayloadNormalizer.php`
  - `SecurityComplianceCoverageComparator.php`
  - `SecurityComplianceRenderableSummaryBuilder.php`
  - `SecurityComplianceReadinessEvaluator.php`
- Wired selected Security/Compliance summary and comparator dispatch into `CoverageV2ReadinessReadModel.php` using the existing Entra and Exchange/Teams pattern.
- Wired `CoverageEvidenceWriter.php` so only selected mandatory Security/Compliance content-backed payloads with renderable summaries promote to `renderable`.
- Hardened `ClaimGuard.php` so only selected scoped internal/operator comparable/renderable/ready-for-operator-review language is allowed; broad Security/Compliance, Purview, certification, restore/apply, legal/regulatory, customer, Review Pack, and 100 percent claims are blocked.
- Reused `CoveragePayloadRedactor.php`; no extension was required. Additional helper-local content redaction covers provider responses, fingerprints, DLP incident/mail/file/case/security incident content, and similar content-bearing keys before summaries/compare output.
- Optional `autoSensitivityLabelPolicy`, `protectionAlert`, and `complianceTag` remain deferred because the current repo has no bounded evidence/test proof sufficient for default-visible operator summaries.

## Implemented Type Matrix

| Canonical type | Normalizer | Compare | Render summary | Readiness | Claim Guard | Promotion |
| --- | --- | --- | --- | --- | --- | --- |
| `retentionCompliancePolicy` | implemented | implemented | implemented | implemented | scoped internal only | `renderable` for supported content-backed evidence |
| `labelPolicy` | implemented | implemented | implemented | implemented | scoped internal only | `renderable` for supported content-backed evidence |
| `dlpCompliancePolicy` | implemented | implemented | implemented | implemented | scoped internal only | `renderable` for supported content-backed evidence |
| `autoSensitivityLabelPolicy` | deferred | deferred | deferred | deferred | unsafe broad claims blocked | remains registry/detected only |
| `protectionAlert` | deferred | deferred | deferred | deferred | unsafe broad claims blocked | remains registry/detected only |
| `complianceTag` | deferred | deferred | deferred | deferred | unsafe broad claims blocked | remains registry/detected only |

## Product Surface Close-Out

- **No-legacy posture**: no legacy UI path, no completed-spec rewrite, no alternate ownership key, no `tenant_id`.
- **Product Surface Impact**: existing Coverage v2 readiness/inspect surface gains selected Security/Compliance typed summaries, compare details, readiness labels, and redaction diagnostics for existing content-backed evidence.
- **UI Surface Impact**: no new route, navigation item, dashboard, action, table, panel, provider, asset, or page class. Existing inspector content changes only when selected Security/Compliance renderable evidence is present.
- **Page archetype**: Technical Annex Page / read-only evidence inspection.
- **Surface budgets**: decision first (`Review readiness`, `Manual review required` / `Ready for operator review`), diagnostics second (`Compare summary`, redacted/unsupported fields), support/raw context third and collapsed under existing technical details.
- **Technical Annex / deep-link demotion**: existing technical details remain collapsed by default; evidence hash, source contract/schema, source class, and operation link are not default-visible.
- **Canonical status vocabulary**: bounded readiness states only: `readiness_not_assessed`, `readiness_ready_for_operator_review`, `readiness_requires_manual_review`, `readiness_blocked_identity`, `readiness_blocked_evidence`, `readiness_blocked_permission`, `readiness_blocked_unsupported`.
- **Product Surface exceptions**: none.
- **Focused browser proof**: `cd apps/platform && ./vendor/bin/sail artisan test tests/Browser/Spec423SecurityComplianceComparableRenderableOperatorSurfaceSmokeTest.php` passed, proving rendered DLP inspector output, collapsed technical details, no raw/secrets/content values, no customer/legal/certification/restore wording, no remote Graph/TCM/provider resource calls, and no JavaScript/console errors.
- **Human Product Sanity result**: pass. An internal operator can see that a DLP policy requires manual review because mode/rule behavior changed, without seeing raw payloads, secrets, DLP incident content, or overclaim wording.
- **Visible complexity outcome**: unchanged page structure; added summary fields reuse the existing inspector hierarchy and do not introduce nested cards, new actions, or new navigation.
- **Livewire v4**: unchanged; platform uses Livewire v4 and tests mount/render the existing Filament surface.
- **Filament provider registration**: unchanged; Laravel 12 provider registration remains in `apps/platform/bootstrap/providers.php`.
- **Global search**: unchanged; no resources/pages were added or made globally searchable.
- **Destructive/high-impact actions**: none added.
- **Asset strategy**: no new assets and no new `filament:assets` deployment requirement.

## Validation

- Initial pre-review validation:
  - `cd apps/platform && ./vendor/bin/sail artisan test --filter=Spec423` -> passed, 62 tests / 297 assertions, including browser smoke.
  - `cd apps/platform && ./vendor/bin/sail artisan test tests/Browser/Spec423SecurityComplianceComparableRenderableOperatorSurfaceSmokeTest.php` -> passed, 1 test / 63 assertions.
  - `cd apps/platform && ./vendor/bin/sail artisan test --filter=ClaimGuard` -> passed, 107 tests / 120 assertions.
  - `cd apps/platform && ./vendor/bin/sail artisan test --filter='Spec421|Spec422'` -> passed, 96 tests / 500 assertions, including existing Spec 421 and Spec 422 browser smokes.
  - `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent` -> passed.
- Post-review hardening validation:
  - `cd apps/platform && php artisan test --compact tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceComparablePayloadNormalizerTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceCoverageComparatorTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceReadinessEvaluatorTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceRenderableSummaryBuilderTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceClaimGuardTest.php` -> passed, 55 tests / 188 assertions.
  - `cd apps/platform && php artisan test --compact tests/Feature/TenantConfiguration/Spec423SecurityComplianceCoverageReadinessTest.php tests/Feature/TenantConfiguration/Spec423SecurityComplianceCoverageAuthorizationTest.php` -> passed, 14 tests / 75 assertions.
  - `cd apps/platform && ./vendor/bin/pint app/Services/TenantConfiguration/SecurityComplianceComparablePayloadNormalizer.php app/Services/TenantConfiguration/ClaimGuard.php app/Services/TenantConfiguration/SecurityComplianceCoverageComparator.php app/Services/TenantConfiguration/SecurityComplianceReadinessEvaluator.php app/Services/TenantConfiguration/SecurityComplianceRenderableSummaryBuilder.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceComparablePayloadNormalizerTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceCoverageComparatorTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceReadinessEvaluatorTest.php tests/Unit/Support/TenantConfiguration/Spec423SecurityComplianceClaimGuardTest.php tests/Feature/TenantConfiguration/Spec423SecurityComplianceCoverageReadinessTest.php tests/Browser/Spec423SecurityComplianceComparableRenderableOperatorSurfaceSmokeTest.php --format agent` -> passed.
  - `cd apps/platform && ./vendor/bin/sail artisan test --filter=Spec423 --compact` -> attempted after post-review hardening; aborted after 60 seconds with no output because Sail/Docker exec was not progressing in this session.
  - `cd apps/platform && php artisan test --compact tests/Browser/Spec423SecurityComplianceComparableRenderableOperatorSurfaceSmokeTest.php` -> local Browser lane timed out before assertions at `visit(...)->resize(...)`; latest successful Browser proof remains the initial Sail Browser run above.
- `git diff --check` -> passed.
- Static service guard: fixed-string scan over touched Security/Compliance helpers and `ClaimGuard.php` found no `GraphClientInterface`, `Http::`, `tenant_id`, `restore-ready`, `certification-ready`, `legal-ready`, `customer-ready`, `ReviewPack`, or nested SecurityCompliance namespace.

## Post-Implementation Analysis

- **Loop count**: 1 completed implementation loop after initial red/green test cycle.
- **Confirmed in-scope findings fixed during loop**:
  - Display-name fields were too strict in the retention allowlist and blocked renderable promotion.
  - Volatile and redacted roots needed diagnostic treatment without becoming material compare changes.
  - Manual-review compare status needed to surface as `Manual review required`.
  - Broad "complete compliance coverage" wording needed Claim Guard blocking.
  - Root redaction and nested content redaction needed different manual-review behavior.
  - Nested unsupported Security/Compliance material fields needed manual-review diagnostics without leaking nested detector/content values.
  - Generic "full coverage", "complete coverage", and "all coverage" wording needed Claim Guard blocking.
- **Remaining in-scope findings**: none found in service, unit, feature, formatting, diff, and static-guard validation. Post-review Sail/Browser re-run remains an environment validation gap, not a confirmed code finding.

## Deployment Impact

- **Migrations**: none.
- **Environment variables**: none.
- **Queues / scheduler / workers**: none.
- **Storage / volumes**: none.
- **Runtime assets**: none.
- **Provider registration**: none.
- **External services**: no new live Graph, TCM, provider, HTTP, Microsoft docs, or remote network calls.
- **Staging / production**: deploy as normal code-only change; no database, config, queue, cron, storage, reverse-proxy, or asset-publish step introduced.

## Residual Risks / Follow-Up Candidates

- Optional Security/Compliance types remain intentionally deferred until a later spec proves content-backed evidence, redaction, render, compare, readiness, RBAC, browser, and no-remote behavior.
- This pack does not add live capture/source contracts; it only renders and compares existing or synthetic content-backed Coverage v2 evidence.
- Readiness is internal operator readiness only. It is not restore readiness, certification, legal/regulatory attestation, customer proof, or a Security/Purview platform.
