- 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.

# Signals DSSE Evidence Staging (runtime/signals gaps)
|
||
|
||
Artifacts prepared 2025-12-01 (UTC) for DSSE signing and Evidence Locker ingest:
|
||
|
||
- Decay config: `docs/modules/signals/decay/confidence_decay_config.yaml`
|
||
- Unknowns scoring manifest: `docs/modules/signals/unknowns/unknowns_scoring_manifest.json`
|
||
- Heuristic catalog + schema + fixtures: `docs/modules/signals/heuristics/`
|
||
- Checksums: `docs/modules/signals/SHA256SUMS`
|
||
|
||
Planned Evidence Locker paths (to fill post-signing):
|
||
- `evidence-locker/signals/decay/2025-12-01/confidence_decay_config.dsse`
|
||
- `evidence-locker/signals/unknowns/2025-12-01/unknowns_scoring_manifest.dsse`
|
||
- `evidence-locker/signals/heuristics/2025-12-01/heuristics_catalog.dsse`
|
||
- `evidence-locker/signals/heuristics/2025-12-01/fixtures/` (golden inputs/outputs)
|
||
|
||
Pending steps:
|
||
0) Provide signing key: CI/ops should supply `COSIGN_PRIVATE_KEY_B64` (base64 of private key) and optional `COSIGN_PASSWORD`. Local dev can place a key at `tools/cosign/cosign.key` (see `tools/cosign/cosign.key.example` stub) or decode the env var to `/tmp/cosign.key`. The helper script `tools/cosign/sign-signals.sh` auto-detects the key and cosign version.
|
||
1) Sign each artifact with its predicate (cosign v3.0.2 in `/usr/local/bin`, use `--bundle`; v2.6.0 fallback in `tools/cosign` also works with `--output-signature`):
|
||
- `stella.ops/confidenceDecayConfig@v1`
|
||
- `stella.ops/unknownsScoringManifest@v1`
|
||
- `stella.ops/heuristicCatalog@v1`
|
||
Shortcut: `OUT_DIR=evidence-locker/signals/2025-12-01 tools/cosign/sign-signals.sh`
|
||
Example (v3, replace KEY):
|
||
```bash
|
||
cosign sign-blob \
|
||
--key cosign.key \
|
||
--predicate-type stella.ops/confidenceDecayConfig@v1 \
|
||
--bundle confidence_decay_config.sigstore.json \
|
||
decay/confidence_decay_config.yaml
|
||
```
|
||
v2.6.0 fallback (if PATH prefixed with `tools/cosign`):
|
||
```bash
|
||
cosign sign-blob \
|
||
--key cosign.key \
|
||
--predicate-type stella.ops/confidenceDecayConfig@v1 \
|
||
--output-signature confidence_decay_config.dsse \
|
||
decay/confidence_decay_config.yaml
|
||
```
|
||
2) Record SHA256 from `SHA256SUMS` in DSSE annotations (or bundle metadata); keep canonical filenames:
|
||
- v3: `confidence_decay_config.sigstore.json`, `unknowns_scoring_manifest.sigstore.json`, `heuristics_catalog.sigstore.json`
|
||
- v2 fallback: `.dsse` signatures.
|
||
3) Place signed envelopes + checksums in the Evidence Locker paths above; update sprint tracker Delivery Tracker rows 5–7 and Decisions & Risks with the final URIs.
|
||
4) Add signer/approver IDs to the sprint Execution Log once signatures are complete.
|
||
|
||
Notes:
|
||
- Use UTC timestamps in DSSE `issuedAt`.
|
||
- Ensure offline parity by copying envelopes + SHA256SUMS into the offline kit bundle when ready.
