+# Strukturierter Test-Plan für DiscoveryCacheManager Refactoring
+
+## Problem
+- Discovery läuft in Timeout (>10 Sekunden)
+- Vollständige Discovery ist zu langsam für Unit-Tests
+- Tests sollten isoliert und schnell sein
+
+## Test-Strategie
+
+### 1. Unit-Tests (Isoliert, ohne Discovery)
+- ✅ Value Objects Tests (bereits vorhanden)
+- ✅ Service Tests (bereits vorhanden)
+- ⚠️ CacheManager Tests mit Mock-Daten
+
+### 2. Integration-Tests (Schnell, mit Mock-Registry)
+- Cache Storage/Retrieval mit vorgefertigten Registry-Objekten
+- Keine echte Discovery-Performance
+
+### 3. Performance-Tests (Optional, separat)
+- Nur wenn nötig, mit Timeout-Schutz
+
+## Test-Kategorien
+
+### Kategorie 1: Value Objects (✅ Fertig)
+- CacheEntry
+- CacheEntryMetadata
+- StalenessCheckResult
+- CacheRetrievalResult
+- CacheStorageResult
+
+### Kategorie 2: Services (✅ Fertig)
+- CacheEntrySerializer
+- StalenessChecker
+- CacheEntryValidator
+- CacheEntryUpgrader
+
+### Kategorie 3: CacheManager (⚠️ Zu testen)
+- Store/Retrieve ohne Discovery
+- Serialization/Deserialization
+- Upgrade von altem Format
+- Staleness Detection
+

+# Test-Zusammenfassung: DiscoveryCacheManager Refactoring
+
+## ✅ Erfolgreich getestet (24 Tests, 69 Assertions)
+
+### Value Objects Tests (5 Tests)
+- ✅ CacheEntry - Erstellung, Serialisierung, Kompression
+- ✅ CacheEntryMetadata - Metadaten-Struktur
+- ✅ StalenessCheckResult - Fresh/Stale Logik
+- ✅ CacheRetrievalResult - Retrieval-Ergebnisse
+- ✅ CacheStorageResult - Storage-Ergebnisse
+
+### Service Tests (19 Tests)
+- ✅ CacheEntrySerializer - Serialisierung/Deserialisierung
+- ✅ StalenessChecker - Staleness-Detection
+- ✅ CacheEntryValidator - Validierung
+- ✅ CacheEntryUpgrader - Format-Upgrade
+
+## ⚠️ Bekannte Probleme
+
+### 1. Discovery Timeout
+- **Problem**: Vollständige Discovery dauert >10 Sekunden
+- **Ursache**: Verarbeitung von 3000+ Dateien
+- **Lösung**: Tests verwenden isolierte Mock-Daten, keine echte Discovery
+
+### 2. CacheManager Integration Test
+- **Problem**: `get()` gibt null zurück trotz vorhandener Cache-Daten
+- **Mögliche Ursachen**:
+  - Staleness-Prüfung schlägt fehl (Pfad wurde modifiziert)
+  - Deserialisierung schlägt fehl
+  - Validierung schlägt fehl
+- **Status**: In Bearbeitung
+
+## Test-Strategie
+
+### ✅ Unit-Tests (Isoliert)
+- Value Objects: Alle Tests bestehen
+- Services: Alle Tests bestehen
+- Keine Discovery-Performance-Probleme
+
+### ⚠️ Integration-Tests
+- CacheManager: Teilweise funktional
+- Benötigt weitere Debugging
+
+### 📝 Empfehlungen
+
+1. **Für schnelle Tests**: Nur Unit-Tests ausführen
+   ```bash
+   ./vendor/bin/pest tests/Framework/Discovery/Storage/ValueObjects tests/Framework/Discovery/Storage/Services
+   ```
+
+2. **Für vollständige Tests**: Mit Timeout-Schutz
+   ```bash
+   timeout 30 ./vendor/bin/pest tests/Framework/Discovery/Storage
+   ```
+
+3. **Für Production-Tests**: Separate Performance-Tests mit Mock-Daten
+
+## Refactoring-Status
+
+### ✅ Abgeschlossen
+- Phase 1: Value Objects (5 VOs)
+- Phase 2: Services (4 Services)
+- Phase 3: DiscoveryCacheManager Refactoring
+- Phase 4: Tests (24 Tests)
+
+### ⚠️ Offen
+- CacheManager Integration-Tests debuggen
+- Performance-Optimierung für Discovery
+

+# Timestamp Migration - Status
+
+## ✅ Abgeschlossen
+
+### CacheEntry
+- ✅ Verwendet jetzt `Timestamp` statt `DateTimeInterface`
+- ✅ `toArray()` serialisiert als `int` timestamp
+- ✅ `fromArray()` deserialisiert von `int`, `float`, `string` oder `DateTimeInterface`
+
+### Services
+- ✅ `StalenessChecker` konvertiert `Timestamp` zu `DateTimeInterface` für Vergleich
+- ✅ `CacheEntryUpgrader` konvertiert `DateTimeInterface` zu `Timestamp`
+- ✅ `CacheEntrySerializer` verwendet `Timestamp::now()` für Fallbacks
+
+### DiscoveryCacheManager
+- ✅ Konvertiert `DiscoveryContext->startTime` (DateTimeInterface) zu `Timestamp` beim Erstellen von `CacheEntry`
+- ✅ Konvertiert `Timestamp` zu `DateTimeInterface` für `CacheEntryMetadata`
+
+## ⚠️ Bekanntes Problem
+
+### Registry Deserialization
+**Problem**: Registry wird als `__PHP_Incomplete_Class` deserialisiert
+
+**Ursache**: 
+- Cache serialisiert das Array mit Registry-Objekt
+- Beim Deserialisieren wird Registry zu `__PHP_Incomplete_Class`, wenn die Klasse nicht geladen ist
+- Dies passiert, wenn `unserialize()` aufgerufen wird, bevor die Klasse geladen ist
+
+**Mögliche Lösungen**:
+1. Registry explizit serialisieren, bevor es in Array eingefügt wird
+2. Cache-Serializer so konfigurieren, dass er Klassen automatisch lädt
+3. Registry-Objekt separat serialisieren und als String im Array speichern
+
+**Status**: In Bearbeitung
+
+## Nächste Schritte
+
+1. Registry-Deserialisierung Problem lösen
+2. Integration-Tests debuggen
+3. Performance-Tests mit Timestamp
