+
+## Technical Highlights
+
+### Deterministic Attestations
+
+Verdict predicates include a **determinism hash** computed from:
+- Sorted evidence digests (SHA256)
+- Verdict status/severity/score
+- Policy version
+
+This enables **bit-for-bit replay verification**: same inputs → same hash.
+
+### DSSE Envelope Format
+
+Attestations use Dead Simple Signing Envelope (DSSE) standard:
+```json
+{
+  "payloadType": "application/vnd.stellaops.verdict+json",
+  "payload": "<base64-encoded-predicate>",
+  "signatures": [{
+    "keyid": "...",
+    "sig": "<base64-signature>"
+  }]
+}
+```
+
+### Offline-First Design
+
+- No hard dependencies on external services
+- Feature-flagged via `VerdictAttestationOptions.Enabled`
+- Optional Rekor transparency log integration
+- Air-gap compatible with deterministic replay

+
+### Blocked ⚠️
+
+- [ ] Policy Engine compiles and runs
+- [ ] Attestor handler signs predicates
+- [ ] End-to-end integration test passes
+- [ ] Deterministic replay verification works

+## Known Issues
+
+### Critical Blockers
+
+1. **PolicyExplainTrace undefined** - Policy Engine can't compile
+2. **Attestor.ProofChain build errors** - Can't implement signing handler
+3. **No policy trace data** - Policy Engine doesn't expose execution trace
+
+### Non-Critical Issues
+
+1. **Verify endpoint stubbed** - Returns placeholder response, needs implementation
+2. **EvidencePortableBundleService errors** - Pre-existing, unrelated to verdict work
+
+## Security Considerations
+
+### Implemented
+
+- ✅ DSSE envelope signature standard
+- ✅ SHA256 digests for evidence
+- ✅ Determinism hash for replay protection
+- ✅ PostgreSQL audit trigger for attestation changes
+
+### Pending
+
+- ⏸️ Actual signature verification (stubbed)
+- ⏸️ Rekor transparency log submission
+- ⏸️ Key rotation support
+- ⏸️ Attestation expiry/revocation
+
+## Performance Notes
+
+### Database
+
+- GIN index on `envelope` JSONB column for fast queries
+- B-tree indexes on `run_id`, `finding_id`, `(tenant_id, evaluated_at)`
+- Pagination support (max 200 results per request)
+
+### Serialization
+
+- Canonical JSON uses lexicographic key ordering
+- Determinism hash computed once, stored for replay
+- Base64 encoding for DSSE payload
+
+## Future Enhancements (Post-Sprint)
+
+### Evidence Packs (SPRINT_3000_0100_0002)
+
+Compressed tarballs containing complete policy evaluation context:
+- SBOM snapshot
+- Advisory snapshots
+- VEX documents
+- Verdict attestations
+- Policy definition
+- Deterministic replay manifest
+
+### Base Image Detection (SPRINT_3000_0100_0003)
+
+Identify base images in container layers:
+- Binary file signature matching
+- Package manifest correlation
+- UI annotation of base vs. added packages
+
+### UI Integration (SPRINT_4000_0100_001-002)
+
+- Reachability proof panels
+- Vulnerability annotation
+- Verdict verification UI
+- Evidence chain visualization
+
+## Support & Maintenance
+
+### Database Migrations
+
+Migration file location: `src/EvidenceLocker/StellaOps.EvidenceLocker/Migrations/`
+
+Run manually:
+```sql
+\i 001_CreateVerdictAttestations.sql
+```
+
+Or via EvidenceLockerMigrationRunner on service startup.
+
+### Monitoring
+
+Log events to watch:
+- `Storing verdict attestation {VerdictId}` - Successful attestation
+- `Verdict attestation {VerdictId} not found` - Missing verdict query
+- `Error retrieving verdict attestation {VerdictId}` - Database error
+
+OpenTelemetry traces: Enabled via existing instrumentation.
+
+### Rollback Procedure
+
+If issues arise:
+
+1. **Disable Feature Flag**:
+   ```json
+   {
+     "VerdictAttestation": {
+       "Enabled": false
+     }
+   }
+   ```
+
+2. **Database Rollback** (if needed):
+   ```sql
+   DROP TABLE IF EXISTS evidence_locker.verdict_attestations CASCADE;
+   DROP FUNCTION IF EXISTS evidence_locker.audit_verdict_attestations_changes();
+   ```
+
+3. **Code Rollback**:
+   ```bash
+   git revert <commit-range>
+   ```
