feat: Implement ILockRepository interface and LockRepository class

- Defined ILockRepository interface with methods for acquiring and releasing locks.
- Implemented LockRepository class with methods to try acquiring a lock and releasing it, using SQL for upsert operations.

feat: Add SurfaceManifestPointer record for manifest pointers

- Introduced SurfaceManifestPointer to represent a minimal pointer to a Surface.FS manifest associated with an image digest.

feat: Create PolicySimulationInputLock and related validation logic

- Added PolicySimulationInputLock record to describe policy simulation inputs and expected digests.
- Implemented validation logic for policy simulation inputs, including checks for digest drift and shadow mode requirements.

test: Add unit tests for ReplayVerificationService and ReplayVerifier

- Created ReplayVerificationServiceTests to validate the behavior of the ReplayVerificationService under various scenarios.
- Developed ReplayVerifierTests to ensure the correctness of the ReplayVerifier logic.

test: Implement PolicySimulationInputLockValidatorTests

- Added tests for PolicySimulationInputLockValidator to verify the validation logic against expected inputs and conditions.

chore: Add cosign key example and signing scripts

- Included a placeholder cosign key example for development purposes.
- Added a script for signing Signals artifacts using cosign with support for both v2 and v3.

chore: Create script for uploading evidence to the evidence locker

- Developed a script to upload evidence to the evidence locker, ensuring required environment variables are set.

 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
+| 2025-12-02 | Completed AIRGAP-REPLAY-510-013: added `replayPolicy` to manifest schema/sample, ReplayVerifier + controller `/system/airgap/verify` endpoint, and replay depth smoke tests for hash drift/policy freeze. | Implementer |
+| 2025-12-02 | Completed AIRGAP-VERIFY-510-014: introduced `verify-kit.sh` offline verifier (hash/signature/staleness/AV/chunk/policy/receipt) and expanded runbook `docs/airgap/runbooks/import-verify.md`. | Implementer |
 | 2025-12-02 | Completed AIRGAP-MANIFEST-510-010: added offline-kit manifest schema + sample (`docs/airgap/manifest.schema.json`, `docs/airgap/samples/offline-kit-manifest.sample.json`) and offline verifier runbook/script (`src/AirGap/scripts/verify-manifest.sh`, `docs/airgap/runbooks/import-verify.md`). | Implementer |
+| 2025-12-02 | Completed AIRGAP-AV-510-011: added AV/YARA report schema + sample, AV scan runbook, and manifest integration guidance; AV reports now referenced from verifier runbook. | Implementer |
+| 2025-12-02 | Completed AIRGAP-RECEIPTS-510-012: published receipt schema + sample and receipt verifier script; receipts now tie bundle/manifest hashes with optional DSSE digest. | Implementer |
 | 2025-11-26 | Added time telemetry (AIRGAP-TIME-57-002): metrics counters/gauges for anchor age + warnings/breaches; status service now emits telemetry. Full time test suite now passing after aligning tests to stub verifiers. | AirGap Time Guild |
 | 2025-11-26 | Completed AIRGAP-CTL-58-001: status response now includes drift + remaining budget seconds; staleness evaluation exposes seconds_remaining; partial test run (AirGapStateServiceTests) passed. | AirGap Controller Guild |
 | 2025-11-26 | Implemented controller startup diagnostics + telemetry (AIRGAP-CTL-57-001/57-002): AirGap:Startup config, trust-root and rotation validation, metrics/log hooks; ran filtered tests `AirGapStartupDiagnosticsHostedServiceTests` (pass). Full suite not run in this session. | AirGap Controller Guild |

 - Local execution risk: runner reports “No space left on device”; cannot run builds/tests until workspace is cleaned. Mitigation: purge transient artefacts or expand volume before proceeding.
 - Test coverage note: only `AirGapStartupDiagnosticsHostedServiceTests` executed after telemetry/diagnostics changes; rerun full controller test suite when feasible.
 - Time telemetry change: full `StellaOps.AirGap.Time.Tests` now passing after updating stub verifier tests and JSON expectations.
-- Manifest schema + verifier script added; downstream tasks 18–21 should reuse `docs/airgap/manifest.schema.json` and `src/AirGap/scripts/verify-manifest.sh` for AV receipts and replay verification.
+- Manifest schema + verifier scripts added; downstream tasks 18–21 should reuse `docs/airgap/manifest.schema.json`, `src/AirGap/scripts/verify-manifest.sh`, and `src/AirGap/scripts/verify-kit.sh` for AV receipts and replay verification.
+- AV runbook/report schema added; importer pipeline must generate `av-report.json` (see `docs/airgap/av-report.schema.json`) and update manifest `avScan` fields; bundles with findings must be rejected before import.
+- Replay depth enforcement added: manifest now requires `replayPolicy`; offline verifier `verify-kit.sh` and controller `/system/airgap/verify` must be used (policy-freeze demands sealed policy hash) to block hash drift and stale bundles.
