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.

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.
