Implementation Report: Spec 414 - TCM-First Coverage v2 Kernel

Preflight

  • Branch: 414-tcm-first-coverage-core-cutover
  • Starting HEAD: fdd9eb2e feat: add focused pilot gate recheck (#480)
  • Starting dirty state: .specify/memory/constitution.md modified; specs/414-tcm-first-coverage-core-cutover/ untracked.
  • Dirty-state assessment: active Spec 414 preparation artifacts only; no runtime code was dirty before implementation.

Scope Close-Out

  • Kernel status: inactive Coverage v2 kernel only.
  • Kernel tables: tenant_configuration_resource_types, tenant_configuration_supported_scopes.
  • Kernel models: TenantConfigurationResourceType, TenantConfigurationSupportedScope.
  • Kernel services: ResourceTypeRegistry, SupportedScopeResolver, ClaimGuard.
  • Kernel value families: SourceClass, Workload, ResourceClass, SupportState, CoverageLevel, EvidenceState, IdentityState, ClaimState, RestoreTier.
  • Runtime UI impact: none.
  • Browser proof: N/A - no rendered UI surface changed.
  • Human Product Sanity: N/A - no rendered UI surface changed; workflow sanity result is that the slice remains inactive and does not create customer-facing dual truth.
  • OperationRun impact: none.
  • Remote provider calls: none.
  • Legacy compatibility: no v1-to-v2 adapter, fallback reader, dual write, old snapshot promotion, or old gap-taxonomy runtime dependency introduced.
  • Optional concrete resource/evidence tables: deferred; the required definition tables and service tests prove the kernel scope without environment-owned observation rows.
  • Provider provenance: required definition tables intentionally omit workspace_id, managed_environment_id, and provider_connection_id; provider-native tenant IDs remain outside Coverage v2 ownership schema.
  • tenant_id proof: required Coverage v2 tables omit tenant_id and any provider-native tenant identifier columns.
  • Policy posture: no policies were added because the new models are inactive platform-seeded definitions with no route, Filament resource, API, or mutation surface. Later activation must add policy/authorization coverage before exposure.

Manual Review Finding Remediation

  • PASS: Supported-scope denominator integrity is fail-closed. SupportedScopeResolver now rejects unknown canonical resource types instead of silently shrinking the denominator before completeness checks.
  • PASS: Denominator fail-closed behavior is covered in both unit and feature lanes, including persisted supported-scope rows.
  • PASS: Spec 414 migration seed semantics are frozen in the migration and no longer depend on mutable runtime registry/resolver services or enum value lists.
  • PASS: A focused schema guard verifies the historical migration does not import App\Services\TenantConfiguration\* or App\Support\TenantConfiguration\* runtime defaults.
  • PASS: Coverage v2 factories now emit JSONB object-shaped metadata, matching the PostgreSQL object check constraints.

Product Surface Close-Out

  • Livewire v4 compliance: Livewire 4.1.4 confirmed; no Livewire code changed.
  • Provider registration location: no panel provider change; Laravel 12 providers remain in apps/platform/bootstrap/providers.php.
  • Global search posture: no Filament resource or global search change.
  • Destructive/high-impact actions: none introduced.
  • Asset strategy: no assets registered; filament:assets is not required for this spec.
  • Visible complexity outcome: neutral; no rendered product surface changed.
  • Deployment impact: additive migrations for inactive kernel definition tables only; no env vars, queues, scheduler, storage, or asset step.
