feat: Add VEX Lens CI and Load Testing Plan

- Introduced a comprehensive CI job structure for VEX Lens, including build, test, linting, and load testing.
- Defined load test parameters and SLOs for VEX Lens API and Issuer Directory.
- Created Grafana dashboards and alerting mechanisms for monitoring API performance and error rates.
- Established offline posture guidelines for CI jobs and load testing.

feat: Implement deterministic projection verification script

- Added `verify_projection.sh` script for verifying the integrity of projection exports against expected hashes.
- Ensured robust error handling for missing files and hash mismatches.

feat: Develop Vuln Explorer CI and Ops Plan

- Created CI jobs for Vuln Explorer, including build, test, and replay verification.
- Implemented backup and disaster recovery strategies for MongoDB and Redis.
- Established Merkle anchoring verification and automation for ledger projector.

feat: Introduce EventEnvelopeHasher for hashing event envelopes

- Implemented `EventEnvelopeHasher` to compute SHA256 hashes for event envelopes.

feat: Add Risk Store and Dashboard components

- Developed `RiskStore` for managing risk data and state.
- Created `RiskDashboardComponent` for displaying risk profiles with filtering capabilities.
- Implemented unit tests for `RiskStore` and `RiskDashboardComponent`.

feat: Enhance Vulnerability Detail Component

- Developed `VulnerabilityDetailComponent` for displaying detailed information about vulnerabilities.
- Implemented error handling for missing vulnerability IDs and loading failures.

+# 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:
+1) Sign each artifact with its predicate:
+   - `stella.ops/confidenceDecayConfig@v1`
+   - `stella.ops/unknownsScoringManifest@v1`
+   - `stella.ops/heuristicCatalog@v1`
+   Example (replace KEY):
+   ```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) Attach SHA256 from `SHA256SUMS` in DSSE headers/annotations.
+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.
