Beschreibung
Implementiert das Drift MVP Feature (Spec: 044-drift-mvp) mit Fokus auf automatische Drift-Erkennung zwischen Inventory Sync Runs und Bulk-Triage für Findings.

Was wurde implementiert?
Drift-Erkennung: Vergleicht Policy-Snapshots, Assignments und Scope Tags zwischen Baseline- und Current-Runs. Deterministische Fingerprints verhindern Duplikate.
Findings UI: Neue Filament Resource für Findings mit Listen- und Detail-Ansicht. DB-only Diffs (keine Graph-Calls zur Laufzeit).
Bulk Acknowledge:
"Acknowledge selected" (Bulk-Action auf der Liste)
"Acknowledge all matching" (Header-Action, respektiert aktuelle Filter; Type-to-Confirm bei >100 Findings)
Scope Tag Fix: Behebt False Positives bei Legacy-Daten ohne scope_tags.ids (inferiert Default-Werte).
Authorization: Tenant-isoliert, Rollen-basiert (Owner/Manager/Operator können acknowledge).
Tests: Vollständige Pest-Coverage (28 Tests, 347 Assertions) für Drift-Logik, UI und Bulk-Actions.
Warum diese Änderungen?
Problem: Keine automatisierte Drift-Erkennung; manuelle Triage bei vielen Findings ist mühsam.
Lösung: Async Drift-Generierung mit persistenter Findings-Tabelle. Safe Bulk-Tools für Massen-Triage ohne Deletes.
Konformität: Folgt AGENTS.md Workflow, Spec-Kit (Tasks + Checklists abgehakt), Laravel/Filament Best Practices.
Technische Details
Neue Dateien: ~40 (Models, Services, Tests, Views, Migrations)
Änderungen: Filament Resources, Jobs, Policies
DB: Neue findings Tabelle (JSONB für Evidence, Indexes für Performance)
Tests: ./vendor/bin/sail artisan test tests/Feature/Drift --parallel → 28 passed
Migration: ./vendor/bin/sail artisan migrate (neue Tabelle + Indexes)

Phase 1 Design: Data Model (044)

Entities

Finding

New table: findings

Purpose: Generic, persisted pipeline for analytic findings (Drift now; Audit/Compare later).

Core fields (MVP)

  • id (pk)
  • tenant_id (fk tenants)
  • finding_type (drift in MVP; later audit/compare)
  • scope_key (string; deterministic; reuse Inventory selection hash)
  • baseline_run_id (nullable fk inventory_sync_runs)
  • current_run_id (nullable fk inventory_sync_runs)
  • fingerprint (string; deterministic)
  • subject_type (string; e.g. policy type)
  • subject_external_id (string; Graph external id)
  • severity (low|medium|high; MVP default medium)
  • status (new|acknowledged)
  • acknowledged_at (nullable)
  • acknowledged_by_user_id (nullable fk users)
  • evidence_jsonb (jsonb; sanitized, small; allowlist)

Prepared for later (nullable, out of MVP)

  • rule_id, control_id, expected_value, source

Constraints & Indexes

Uniqueness

  • Unique: (tenant_id, fingerprint)

Lookup indexes (suggested)

  • (tenant_id, finding_type, status)
  • (tenant_id, scope_key)
  • (tenant_id, current_run_id)
  • (tenant_id, baseline_run_id)
  • (tenant_id, subject_type, subject_external_id)

Relationships

  • Finding belongs to Tenant.
  • Finding belongs to User via acknowledged_by_user_id.
  • Finding belongs to InventorySyncRun via baseline_run_id (nullable) and current_run_id (nullable).

Evidence shape (MVP allowlist)

For Drift MVP, evidence_jsonb should contain only:

  • change_type
  • changed_fields (list) and/or change_counts
  • run:
    • baseline_run_id, current_run_id
    • baseline_finished_at, current_finished_at

No raw policy payload dumps; exclude secrets/tokens; exclude volatile fields for hashing.
