# Air-Gap Bundle System (DSSE-Signed Bundle Format with Import/Export)
## Module
AirGap
## Status
IMPLEMENTED
## Description
Comprehensive air-gap bundle system with DSSE signing and verification, bundle format with schemas/validation/trust snapshots, controller for state management, importer with quarantine-on-failure, atomic feed activation with rollback, file-based and router-based delivery transport, and offline kit validation (monotonicity checking, telemetry metrics). Covers offline update kits (OUK), replay packs, and audit pack export/import.
## Implementation Details
- **Controller**: `src/AirGap/StellaOps.AirGap.Controller/` -- state management (`AirGapState.cs`, `AirGapStateService.cs`), endpoints (`AirGapEndpoints.cs` with seal/verify), startup options, telemetry
- **Importer**: `src/AirGap/StellaOps.AirGap.Importer/` -- bundle planning (`BundleImportPlanner.cs`), quarantine on failure (`FileSystemQuarantineService.cs`, `IQuarantineService.cs`), evidence reconciliation (`EvidenceReconciler.cs`, `EvidenceGraph.cs`), SBOM/DSSE parsers, version monotonicity, trust root config, replay verification
- **Bundle library**: `src/AirGap/__Libraries/StellaOps.AirGap.Bundle/` -- bundle format, schema validation, trust snapshot management
- **Sync library**: `src/AirGap/__Libraries/StellaOps.AirGap.Sync/` -- synchronization for bundle delivery
- **Persistence**: `src/AirGap/__Libraries/StellaOps.AirGap.Persistence/` and `src/AirGap/StellaOps.AirGap.Storage.Postgres/`
- **Policy**: `src/AirGap/StellaOps.AirGap.Policy/` -- offline verification policy, analyzers
- **Tests**: Controller, Importer, Persistence, Sync, Time, and Policy tests under `src/AirGap/__Tests/`
- **Source**: Feature matrix scan
## E2E Test Plan
- [ ] Test bundle import with valid DSSE-signed bundle, verify state transition
- [ ] Test quarantine behavior on invalid bundle signature
- [ ] Test monotonicity check rejects older bundle version
- [ ] Test evidence reconciliation correctly parses CycloneDx, DSSE attestations
- [ ] Test atomic feed activation and rollback on failure
- [ ] Verify bundle import planning produces correct plan
