Add determinism tests for verdict artifact generation and update SHA256 sums script

- Implemented comprehensive tests for verdict artifact generation to ensure deterministic outputs across various scenarios, including identical inputs, parallel execution, and change ordering.
- Created helper methods for generating sample verdict inputs and computing canonical hashes.
- Added tests to validate the stability of canonical hashes, proof spine ordering, and summary statistics.
- Introduced a new PowerShell script to update SHA256 sums for files, ensuring accurate hash generation and file integrity checks.

-# Archived: Attestor UI Notes
+# Attestor UI (Console)
 
-This page was consolidated into canonical docs:
+The Console includes surfaces for viewing and verifying attestations produced by StellaOps services.
 
-- `docs/15_UI_GUIDE.md`
-- `docs/modules/attestor/architecture.md`
+## Views
 
-The previous note has been archived to:
+- **Attestation list:** filter by tenant, issuer, predicate/type, verification status.
+- **Attestation detail:** show subject, predicate, timestamps, signer identity, and verification outcome.
+- **Verification panel:** signature status, certificate chain/key identity, and transparency proof (when configured).
 
-- `docs/_archive/console/attestor-ui.md`
+## Actions
+
+- Download DSSE envelope (and referenced artifacts where applicable)
+- Copy digests and correlation IDs for audit trails
+- Open transparency proof details (when enabled)
+
+## Guardrails
+
+- The UI must not “derive” verdicts from attestations; it should display verification state and referenced evidence.
+- Tenancy must always be explicit; exports should preserve tenant context and verification metadata.
