+/**
+ * Mission Factory Parity Integration Tests - Engine
+ *
+ * These tests verify that Factory mission behavior stays consistent across
+ * the scheduler/autopilot/runtime integration. They test:
+ * - Scheduler mission completion paths synchronize feature status
+ * - Failure/retry round behavior is consistent
+ * - Blocked mission paths don't schedule or auto-advance
+ * - Runtime startup recovery executes deterministically
+ *
+ * Run: pnpm --filter @fusion/engine exec vitest run src/mission-factory-parity.integration.test.ts
