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

# Cosign binaries (runtime/signals signing)
|
|
|
|
## Preferred (system)
|
|
- Version: `v3.0.2`
|
|
- Path: `/usr/local/bin/cosign` (installed on WSL Debian host)
|
|
- Breaking change: v3 requires `--bundle <file>` when signing blobs; older `--output-signature`/`--output-certificate` pairs are deprecated.
|
|
|
|
## Offline fallback (repo-pinned)
|
|
- Version: `v2.6.0`
|
|
- Binary: `tools/cosign/cosign` → `tools/cosign/v2.6.0/cosign-linux-amd64`
|
|
- SHA256: `ea5c65f99425d6cfbb5c4b5de5dac035f14d09131c1a0ea7c7fc32eab39364f9`
|
|
- Check: `cd tools/cosign/v2.6.0 && sha256sum -c cosign_checksums.txt --ignore-missing`
|
|
|
|
## Usage examples
|
|
- v3 DSSE blob: `cosign sign-blob --key cosign.key --predicate-type stella.ops/confidenceDecayConfig@v1 --bundle confidence_decay_config.sigstore.json decay/confidence_decay_config.yaml`
|
|
- v3 verify: `cosign verify-blob --bundle confidence_decay_config.sigstore.json decay/confidence_decay_config.yaml`
|
|
- To force offline fallback, export `PATH=./tools/cosign:$PATH` (ensures v2.6.0 is used).
|
|
|
|
## CI / secrets
|
|
- CI should provide a base64-encoded private key via secret `COSIGN_PRIVATE_KEY_B64` and optional password in `COSIGN_PASSWORD`.
|
|
- Example bootstrap in jobs:
|
|
```bash
|
|
echo \"$COSIGN_PRIVATE_KEY_B64\" | base64 -d > /tmp/cosign.key
|
|
chmod 600 /tmp/cosign.key
|
|
COSIGN_PASSWORD=\"${COSIGN_PASSWORD:-}\" cosign version
|
|
```
|
|
- For local dev, copy your own key to `tools/cosign/cosign.key` or export `COSIGN_PRIVATE_KEY_B64` before running signing scripts. Never commit real keys; only `cosign.key.example` lives in git.
