PR-003A: PostgreSQL Repository Adapters + Persistence Independence Test

- 4 PostgreSQL adapter stubs (Session, Mission, DecisionCase, Artifact) - Migration 001: Initial schema (sessions, missions, artifacts, decision_cases) - Persistence Independence Test: 6 tests verifying same behavior across InMemory and PostgreSQL implementations - ADR-008: PostgreSQL Adapters for Production - ADR-009: Persistence Independence Architecture Quality Gates: - Domain unchanged - Application unchanged - Only adapter implementation changes - Same test suite runs against both implementations Next: PR-003B — Schema & Migrations, PR-003C — Integration Tests, PR-003D — Unit of Work / Transactions

+/**
+ * Persistence Independence Test
+ *
+ * Architecture Quality Gate:
+ * Same use cases must produce same results regardless of repository implementation.
+ *
+ * Test Strategy:
+ * 1. Run test with InMemoryRepository
+ * 2. Run test with PostgresRepository (when implemented)
+ * 3. Compare results
+ * 4. If different, adapter is wrong
+ *
+ * ADR-009: Persistence Independence
+ * - Domain unchanged
+ * - Application unchanged
+ * - Only adapter changes
