- Introduced DigestUpsertRequest for handling digest upsert requests with properties like ChannelId, Recipient, DigestKey, Events, and CollectUntil.
- Created LockEntity to represent a lightweight distributed lock entry with properties such as Id, TenantId, Resource, Owner, ExpiresAt, and CreatedAt.
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
