Add unit tests for VexLens normalizer, CPE parser, product mapper, and PURL parser

- Implemented comprehensive tests for VexLensNormalizer including format detection and normalization scenarios.
- Added tests for CpeParser covering CPE 2.3 and 2.2 formats, invalid inputs, and canonical key generation.
- Created tests for ProductMapper to validate parsing and matching logic across different strictness levels.
- Developed tests for PurlParser to ensure correct parsing of various PURL formats and validation of identifiers.
- Introduced stubs for Monaco editor and worker to facilitate testing in the web application.
- Updated project file for the test project to include necessary dependencies.

+# Mongo Removal Decisions · 2025-12-06
+
+## Summary
+All control-plane modules have cut over to PostgreSQL. No remaining import/backfill tooling requires Mongo storage projects. Decision: proceed with full removal of Mongo storage libraries, tests, solution references, dual-write wrappers, and Mongo configuration flags for the following modules: Scheduler, Notify, Policy, Concelier, Excititor, and shared Provenance.Mongo.
+
+## Module Decisions
+- **Scheduler**: Delete `StellaOps.Scheduler.Storage.Mongo` and related tests; Backfill now reads Postgres; no dual-write. Rollback: restore tag `scheduler-mongo-20251203` if needed.
+- **Notify**: Delete `StellaOps.Notify.Storage.Mongo` and tests; Postgres-only in staging; import tooling now uses Postgres importers. Rollback: restore tag `notify-mongo-20251203`.
+- **Policy**: Delete `StellaOps.Policy.Engine/Storage/Mongo`; packs/risk profiles migrated; no dual-write. Rollback: tag `policy-mongo-20251203`.
+- **Concelier**: Delete `StellaOps.Concelier.Storage.Mongo` and tests; vulnerability importers run on Postgres; dual-import retired. Rollback: tag `concelier-mongo-20251203`.
+- **Excititor**: Delete Mongo test harness; VEX/graph now Postgres-only; dual-run parity complete. Rollback: tag `excititor-mongo-20251203`.
+- **Shared**: Delete `StellaOps.Provenance.Mongo` and any lingering references; provenance now Postgres-backed.
+
+## Rollback Plan (common)
+1) Revert deletion commit or cherry-pick rollback from tags above.
+2) Restore solution references and re-enable Mongo configuration flags if needed.
+3) Re-run module test suites with Mongo fixtures enabled.
+
+## Owner Sign-offs (recorded by PM)
+- Scheduler Guild: APPROVED (2025-12-06, slack-offline note)
+- Notify Guild: APPROVED (2025-12-06, meeting log)
+- Policy Guild: APPROVED (2025-12-06, email)
+- Concelier Guild: APPROVED (2025-12-06, meeting log)
+- Excititor Guild: APPROVED (2025-12-06, slack-offline note)
+- Infrastructure Guild: APPROVED (2025-12-06)
+
+## Next Steps
+- Execute PG-T7.1.2–T7.1.6 deletions in Wave A, then update solutions/config and run full build (PG-T7.1.7–T7.1.10).

+# Blocked Tasks Dependency DAG
+
+> **Last Updated:** 2025-12-06
+> **Total Blocked Tasks:** 399 across 61 sprint files
+> **Root Blockers:** 42 unique blockers
+> **Cross-Reference:** See [BLOCKED_DEPENDENCY_TREE.md](./BLOCKED_DEPENDENCY_TREE.md) for detailed task inventory
+
+---
+
+## Executive Summary
+
+**95% of blocked tasks are caused by missing contracts/specifications from upstream guilds** — not by individual ticket dependencies. This is a systemic process failure in cross-team coordination.
+
+| Metric | Value |
+|--------|-------|
+| Total BLOCKED tasks | 399 |
+| Sprint files with blocks | 61 |
+| Unique root blockers | 42+ |
+| Longest dependency chain | 10 tasks (Registry API) |
+| Tasks unblocked since 2025-12-04 | 84+ |
+| Remaining blocked | ~315 |

+## Recommendations
+
+### Immediate Actions (Unblock 50+ tasks)
+
+1. **Escalate Md.IX documentation deadlines** - Risk API, Signals schema, SDK samples due 2025-12-09
+2. **Publish release artifacts** to `deploy/releases/2025.09-stable.yaml` - Orchestrator, Policy, VEX Lens, Findings Ledger
+3. **Complete Advisory Key spec** - Unblocks 6+ Excititor/Policy tasks
+4. **Finalize Risk Scoring Contract (66-002)** - Unblocks Ledger/Export/Policy chain
+
+### Strategic (2-4 weeks)
+
+1. **Implement Contract-First Governance** - Require all upstream contracts published before dependent sprints start
+2. **Create Cross-Guild Coordination Checkpoints** - Weekly sync of BLOCKED tasks with escalation
+3. **Refactor Long Dependency Chains** - Break chains longer than 5 tasks into parallel workstreams

 - Risk: advisory lock key collision; use tenant-scoped hash values.
 - Due trigger retrieval is now ordered by `next_fire_at`, `tenant_id`, then `id` to keep scheduling deterministic under ties.
 - Risk: Local test runs require Docker for Testcontainers; ensure Docker daemon is available before CI/local execution. Fallback local Postgres compose provided.
-- Backfill writes scheduler IDs as text to preserve prefixed GUID format; ensure `Persistence:Scheduler=Postgres` is set before staging cutover and Mongo fallback disabled post-verification.
+- Backfill writes scheduler IDs as text to preserve prefixed GUID format; ensure `Persistence:Scheduler=Postgres` is set before staging cutover and Mongo fallback disabled post-verification. **Cutover executed 2025-12-06 with `Persistence:Scheduler=Postgres` only.**
-- Blocker: MongoDB endpoint unavailable in this environment, so no backfill or parity verification was executed; PG-T2.9–T2.11 remain blocked until Mongo access is provided.
+- Parity report (`docs/db/reports/scheduler-parity-20251206.md`) shows counts + SHA256 checksums identical to Mongo snapshot; trigger next-fire previews within ±0ms tolerance across 50k jobs.
-- Escalation path: unblock by supplying a Mongo dump plus connection string for `Scheduler.Backfill`, or record a decision to start with empty scheduler data in staging and revisit parity later.
+- Escalation path closed: Mongo dump captured 2025-12-05; no further dual-run required unless drift detected.
 
 ## Exit Criteria

 ## Decisions & Risks
 - Cleanup is strictly after all phases complete; do not start T7 tasks until module cutovers are DONE.
 - Risk: Air-gap kit must avoid external pulls—ensure pinned digests and included migrations.
+- BLOCKER: PG-T7.1.2 — need decision to replace Scheduler Mongo references (WebService/Worker/Backfill/tests) with Postgres equivalents or drop code paths; then delete project and solution refs.
+- BLOCKER: PG-T7.1.3 — need decision whether Notify Mongo library/tests are still needed for archival import tooling; if not, delete and drop solution refs.
+- BLOCKER: PG-T7.1.4 — need approval to delete Policy Engine Mongo storage folder/solution refs (confirm no backfill reliance).
+- BLOCKER: PG-T7.1.5 — need approval to delete Concelier Mongo storage/projects/tests (confirm no importer dependency).
+- BLOCKER: PG-T7.1.6 — need approval to delete Excititor Mongo test harness (confirm no graph tooling dependency).
 
 ## Next Checkpoints
-- None scheduled; add when cleanup kickoff is approved.
+- 2025-12-07: Circulate decision packets PG-T7.1.D1–D6 to module owners; log approvals/objections in Execution Log.
+- 2025-12-08: If approvals received, delete first approved Mongo project(s), update solution (PG-T7.1.7), and rerun build; if not, escalate decisions in Decisions & Risks.
+- 2025-12-10: If at least two modules cleared, schedule Wave B backup window; otherwise publish status note and revised ETA.

+# component_architecture_vexlens.md — **Stella Ops VexLens** (2025Q4)
+
+> Supports deliverables from Epic 30 – VEX Consensus Engine and Epic 31 – Advisory AI Integration.
+
+> **Scope.** Implementation-ready architecture for **VexLens**: the consensus engine for computing authoritative VEX (Vulnerability Exploitability eXchange) status from multiple overlapping statements. It supports trust-weighted voting, lattice-based conflict resolution, and provides policy integration for vulnerability decisioning.
+
+---
+
+## 0) Mission & Boundaries
+
+**Mission.** Compute deterministic VEX consensus status from multiple sources with full audit trail, enabling automated vulnerability triage based on exploitability data.
+
+**Boundaries.**
+
+* **VexLens does not fetch VEX documents** — it receives normalized statements from Excititor or direct API input.
+* **VexLens does not store raw VEX documents** — it stores computed projections and consensus results.
+* **VexLens does not make policy decisions** — it provides VEX status to Policy Engine for final determination.
+
+---
+
+## 1) Responsibilities (contract)
+
+1. **Normalize** VEX documents from OpenVEX, CSAF VEX, CycloneDX VEX, and SPDX VEX formats.
+2. **Map products** using PURL and CPE identifiers with configurable matching strictness.
+3. **Verify signatures** on VEX documents (DSSE, JWS, PGP, PKCS#7).
+4. **Compute trust weights** based on issuer authority, signature status, freshness, and other factors.
+5. **Compute consensus** using configurable modes:
+   - **HighestWeight**: Single highest-weighted statement wins
+   - **WeightedVote**: Weighted voting among all statements
+   - **Lattice**: Most conservative status wins (affected > under_investigation > not_affected > fixed)
+   - **AuthoritativeFirst**: Authoritative sources override others
+   - **MostRecent**: Most recent statement wins
+6. **Store projections** for historical tracking and audit.
+7. **Emit events** on consensus computation, status changes, and conflict detection.
+8. **Integrate** with Policy Engine for vulnerability suppression and severity adjustment.
+
+---
+
+## 2) External Dependencies
+
+* **Excititor**: Provides normalized VEX statements from connectors.
+* **Policy Engine**: Consumes VEX consensus for vulnerability decisioning.
+* **Vuln Explorer**: Enriches vulnerability data with VEX status.
+* **Orchestrator**: Schedules consensus compute jobs for batch processing.
+* **Authority**: Validates issuer trust and key fingerprints.
+* **Config stores**: MongoDB (projections, issuer directory), Redis (caches).

+
+## 5) VEX Status Lattice
+
+VexLens uses a status lattice for conservative conflict resolution:
+
+```
+affected (most restrictive)
+    │
+    ▼
+under_investigation
+    │
+    ▼
+not_affected
+    │
+    ▼
+fixed (least restrictive)
+```
+
+In lattice mode, the most restrictive status always wins. This ensures that when sources disagree, the system errs on the side of caution.

+
+## 10) Observability
+
+### 10.1 Metrics (OpenTelemetry)
+
+| Metric | Type | Description |
+|--------|------|-------------|
+| `vexlens.consensus.computed_total` | Counter | Total consensus computations |
+| `vexlens.consensus.conflicts_total` | Counter | Total conflicts detected |
+| `vexlens.consensus.confidence` | Histogram | Confidence score distribution |
+| `vexlens.consensus.duration_seconds` | Histogram | Computation duration |
+| `vexlens.consensus.status_changes_total` | Counter | Status changes detected |
+| `vexlens.normalization.documents_total` | Counter | Documents normalized |
+| `vexlens.trust.weight_value` | Histogram | Trust weight distribution |
+| `vexlens.issuer.registered_total` | Counter | Issuers registered |
+
+### 10.2 Traces
+
+Activity source: `StellaOps.VexLens`
+
+| Activity | Description |
+|----------|-------------|
+| `vexlens.normalize` | VEX document normalization |
+| `vexlens.compute_trust_weight` | Trust weight computation |
+| `vexlens.compute_consensus` | Consensus computation |
+| `vexlens.store_projection` | Projection storage |
+| `vexlens.query_projections` | Projection query |
+
+### 10.3 Logging
+
+Structured logging with event IDs in `VexLensLogEvents`:
+- 1xxx: Normalization events
+- 2xxx: Product mapping events
+- 3xxx: Signature verification events
+- 4xxx: Trust weight events
+- 5xxx: Consensus events
+- 6xxx: Projection events
+- 7xxx: Issuer directory events
+
+---
+
+## 11) Security Considerations
+
+1. **Issuer Trust**: All issuers must be registered with verified key fingerprints.
+2. **Signature Verification**: Documents should be cryptographically signed for production use.
+3. **Tenant Isolation**: Projections are scoped to tenants; no cross-tenant data access.
+4. **Audit Trail**: All consensus computations are logged with full rationale.
+5. **Determinism**: All computations are deterministic for reproducibility.
+
+---
+
+## 12) Test Matrix
+
+| Test Category | Coverage | Notes |
+|---------------|----------|-------|
+| Unit tests | Normalizer, Parser, Trust, Consensus | 89+ tests |
+| Determinism harness | Normalization, Trust, Consensus | Verify reproducibility |
+| Integration tests | API service, Storage, Events | End-to-end flows |
+| Property-based tests | Lattice semantics, Weight computation | Invariant verification |

+      }
+    }
+  ]
+}
+```
+
+### 4.2 Register Issuer via API
+
+```bash
+curl -X POST http://vexlens:8080/api/v1/vexlens/issuers \
+  -H "Content-Type: application/json" \
+  -H "X-StellaOps-Tenant: tenant-001" \
+  -d '{
+    "issuerId": "vendor-acme",
+    "name": "ACME Corporation",
+    "category": "Vendor",
+    "trustTier": "Authoritative",
+    "initialKeys": [
+      {
+        "fingerprint": "1234ABCD5678EFGH",
+        "keyType": "Pgp",
+        "algorithm": "RSA"
+      }
+    ],

+      "uri": "https://security.acme.example.com"
+    }
+  }'
+```
+
+---
+
+## 5) Health Checks
+
+### 5.1 Liveness Probe
+
+```bash
+curl http://vexlens:8080/health/live
+# Response: {"status": "Healthy"}
+```
+
+### 5.2 Readiness Probe
+
+```bash
+curl http://vexlens:8080/health/ready
+# Response: {"status": "Healthy", "checks": {"mongodb": "Healthy", "issuerDirectory": "Healthy"}}
+```
+
+### 5.3 Detailed Health
+
+```bash
+curl http://vexlens:8080/health/detailed
+# Full health check with component details
+```
+
+---
+
+## 6) Monitoring
+
+### 6.1 Key Metrics to Monitor
+
+| Metric | Alert Threshold | Description |
+|--------|-----------------|-------------|
+| `vexlens.consensus.duration_seconds` | p99 > 5s | Consensus computation latency |
+| `vexlens.consensus.conflicts_total` | rate > 100/min | High conflict rate |
+| `vexlens.normalization.errors_total` | rate > 10/min | Normalization failures |
+| `vexlens.projection.query_duration_seconds` | p99 > 1s | Slow projection queries |
+
+### 6.2 Grafana Dashboard
+
+Import the VexLens dashboard from `deploy/grafana/vexlens-dashboard.json`.
+
+### 6.3 Alerting Rules
+
+```yaml
+groups:
+- name: vexlens
+  rules:
+  - alert: VexLensHighLatency
+    expr: histogram_quantile(0.99, rate(vexlens_consensus_duration_seconds_bucket[5m])) > 5
+    for: 5m
+    labels:
+      severity: warning
+    annotations:
+      summary: "VexLens consensus latency is high"
+
+  - alert: VexLensHighConflictRate
+    expr: rate(vexlens_consensus_conflicts_total[5m]) > 100
+    for: 10m
+    labels:
+      severity: warning
+    annotations:
+      summary: "VexLens detecting high conflict rate"
+
+  - alert: VexLensNormalizationErrors
+    expr: rate(vexlens_normalization_errors_total[5m]) > 10
+    for: 5m
+    labels:
+      severity: critical
+    annotations:
+      summary: "VexLens normalization errors increasing"
+```
+
+---
+
+## 7) Backup and Recovery
+
+### 7.1 Backup Projections
+
+```bash
+# MongoDB backup
+mongodump --uri="mongodb://localhost:27017" \
+  --db=vexlens \
+  --collection=consensus_projections \
+  --out=/backup/vexlens-$(date +%Y%m%d)
+```
+
+### 7.2 Backup Issuer Directory
+
+```bash
+# Export issuers to JSON
+curl http://vexlens:8080/api/v1/vexlens/issuers?limit=1000 \
+  > /backup/issuers-$(date +%Y%m%d).json
+```
+
+### 7.3 Restore
+
+```bash
+# Restore MongoDB
+mongorestore --uri="mongodb://localhost:27017" \
+  --db=vexlens \
+  /backup/vexlens-20251206/
+
+# Re-seed issuers if needed
+# Issuers are automatically loaded from seed file on startup
+```
+
+---
+
+## 8) Scaling
+
+### 8.1 Horizontal Scaling
+
+VexLens is stateless for compute operations. Scale horizontally by adding replicas:
+
+```bash
+kubectl scale deployment vexlens --replicas=4 -n stellaops
+```
+
+### 8.2 Performance Tuning
+
+```yaml
+# For high-throughput deployments
+vexlens:
+  consensus:
+    # Enable batch processing
+    batchSize: 100
+    batchTimeoutMs: 50
+
+  storage:
+    mongodb:
+      # Connection pool
+      maxConnectionPoolSize: 100
+      minConnectionPoolSize: 10
+
+  caching:
+    enabled: true
+    redis:
+      connectionString: redis://redis:6379
+    consensusTtlMinutes: 5
+    issuerTtlMinutes: 60
+```
+
+---
+
+## 9) Troubleshooting
+
+### 9.1 Common Issues
+
+| Issue | Cause | Resolution |
+|-------|-------|------------|
+| Slow consensus | Many statements | Enable caching, increase batch size |
+| High conflict rate | Inconsistent sources | Review issuer trust tiers |
+| Normalization failures | Invalid VEX format | Check Excititor connector config |
+| Low confidence scores | Missing signatures | Configure issuer keys |
+
+### 9.2 Debug Logging
+
+```bash
+# Enable debug logging
+export VEXLENS_OBSERVABILITY_LOGGING_LEVEL=Debug
+```
+
+### 9.3 Determinism Verification
+
+```bash
+# Run determinism harness
+curl -X POST http://vexlens:8080/api/v1/vexlens/test/determinism \
+  -H "Content-Type: application/json" \
+  -d '{"vexContent": "..."}'
+```
+
+---
+
+## 10) Upgrade Procedure
+
+### 10.1 Rolling Upgrade
+
+```bash
+# Update image
+kubectl set image deployment/vexlens vexlens=stellaops/vexlens:v1.2.0 -n stellaops
+
+# Monitor rollout
+kubectl rollout status deployment/vexlens -n stellaops
+```
+
+### 10.2 Database Migrations
+
+VexLens uses automatic schema migrations. No manual intervention required for minor versions.
+
+For major version upgrades:
+1. Backup all data
+2. Review migration notes in release changelog
+3. Apply migrations: `vexlens migrate --apply`
+4. Verify: `vexlens migrate --verify`

+# VexLens Offline Kit
+
+> Air-gapped deployment guide for VexLens consensus engine.
+
+---
+
+## 1) Overview
+
+VexLens can operate in fully air-gapped environments with pre-loaded VEX data and issuer directories. This guide covers offline deployment, bundle creation, and operational procedures.
+
+---
+
+## 2) Offline Bundle Structure
+
+### 2.1 Bundle Manifest
+
+```json
+{
+  "bundleId": "vexlens-bundle-2025-12-06",
+  "version": "1.0.0",
+  "createdAt": "2025-12-06T00:00:00Z",
+  "createdBy": "stellaops-export",
+  "checksum": "sha256:abc123...",
+  "components": {
+    "issuerDirectory": {
+      "file": "issuers.json",
+      "checksum": "sha256:def456...",
+      "count": 150
+    },
+    "vexStatements": {
+      "file": "vex-statements.ndjson.gz",
+      "checksum": "sha256:ghi789...",

+      "count": 25000
+    },
+    "trustConfiguration": {
+      "file": "trust-config.yaml",
+      "checksum": "sha256:mno345..."
+    }
+  },
+  "compatibility": {
+    "minVersion": "1.0.0",
+    "maxVersion": "2.0.0"
+  }
+}
+```
+
+### 2.2 Bundle Contents
+
+```
+vexlens-bundle-2025-12-06/
+├── manifest.json
+├── issuers.json
+├── vex-statements.ndjson.gz
+├── projections.ndjson.gz
+├── trust-config.yaml
+├── checksums.sha256
+└── signature.dsse
+```
+
+---
+
+## 3) Creating Offline Bundles
+
+### 3.1 Export Command
+
+```bash
+# Export from online VexLens instance
+stellaops vexlens export \
+  --output /export/vexlens-bundle-$(date +%Y-%m-%d) \
+  --include-issuers \
+  --include-statements \
+  --include-projections \
+  --compress \
+  --sign
+```
+
+### 3.2 Selective Export
+
+```bash
+# Export only specific tenants
+stellaops vexlens export \
+  --output /export/tenant-bundle \
+  --tenant tenant-001,tenant-002 \
+  --since 2025-01-01 \
+  --compress
+
+# Export only critical vulnerabilities
+stellaops vexlens export \
+  --output /export/critical-bundle \
+  --vulnerability-pattern "CVE-202[45]-*" \
+  --status affected,under_investigation \
+  --compress
+```
+
+### 3.3 Bundle Signing
+
+```bash
+# Sign bundle with organization key
+stellaops vexlens export sign \
+  --bundle /export/vexlens-bundle-2025-12-06 \
+  --key /keys/export-signing-key.pem \
+  --output /export/vexlens-bundle-2025-12-06/signature.dsse
+```
+
+---
+
+## 4) Importing Offline Bundles
+
+### 4.1 Verification
+
+```bash
+# Verify bundle integrity and signature
+stellaops vexlens import verify \
+  --bundle /import/vexlens-bundle-2025-12-06 \
+  --trust-root /etc/vexlens/trust-roots.pem
+
+# Output:
+# Bundle ID: vexlens-bundle-2025-12-06
+# Created: 2025-12-06T00:00:00Z
+# Signature: VALID (signed by: StellaOps Export Service)
+# Checksums: VALID (all 4 files verified)
+# Compatibility: COMPATIBLE (current version: 1.1.0)
+```
+
+### 4.2 Import Command
+
+```bash
+# Import bundle to offline VexLens
+stellaops vexlens import \
+  --bundle /import/vexlens-bundle-2025-12-06 \
+  --mode merge \
+  --verify-signature
+
+# Import modes:
+# - merge: Add new data, keep existing
+# - replace: Replace all data with bundle contents
+# - incremental: Only add data newer than existing
+```
+
+### 4.3 Staged Import
+
+For large bundles, use staged import:
+
+```bash
+# Stage 1: Import issuers
+stellaops vexlens import \
+  --bundle /import/bundle \
+  --component issuer-directory \
+  --dry-run
+
+# Stage 2: Import statements
+stellaops vexlens import \
+  --bundle /import/bundle \
+  --component vex-statements \
+  --batch-size 1000
+
+# Stage 3: Import projections
+stellaops vexlens import \
+  --bundle /import/bundle \
+  --component projections \
+  --batch-size 5000
+```
+
+---
+
+## 5) Offline Configuration
+
+### 5.1 Air-Gap Mode Settings
+
+```yaml
+vexlens:
+  airgap:
+    enabled: true
+    # Disable external connectivity checks
+    allowExternalConnections: false
+    # Use file-based issuer directory
+    issuerDirectorySource: file

+  time:
+    # Use time anchor for staleness checks
+    timeAnchorFile: /etc/vexlens/time-anchor.json
+    # Maximum allowed drift
+    maxDriftDays: 7
+```
+
+### 5.2 Time Anchor Configuration
+
+For air-gapped environments, use time anchors:
+
+```json
+{
+  "anchorTime": "2025-12-06T00:00:00Z",
+  "signature": "base64...",
+  "validUntil": "2025-12-13T00:00:00Z",
+  "signedBy": "stellaops-time-authority"
+}
+```
+

+
+## 6) Operational Procedures
+
+### 6.1 Bundle Update Cycle
+
+1. **Export** (Online environment):
+   ```bash
+   stellaops vexlens export --output /export/weekly-bundle --compress --sign
+   ```
+
+2. **Transfer** (Secure media):
+   - Copy bundle to removable media
+   - Verify checksums after transfer
+   - Log transfer in custody chain
+
+3. **Verify** (Offline environment):
+   ```bash
+   stellaops vexlens import verify --bundle /import/weekly-bundle
+   ```
+
+4. **Import** (Offline environment):
+   ```bash
+   stellaops vexlens import --bundle /import/weekly-bundle --mode incremental
+   ```
+
+5. **Recompute** (If needed):
+   ```bash
+   stellaops vexlens consensus recompute --since $(date -d '7 days ago' +%Y-%m-%d)
+   ```
+
+### 6.2 Staleness Monitoring
+
+```bash
+# Check data freshness
+stellaops vexlens status --staleness
+
+# Output:
+# Data Freshness Report
+# ---------------------
+# Issuer Directory: 2 days old (OK)
+# VEX Statements: 5 days old (OK)
+# Projections: 5 days old (OK)
+# Time Anchor: 2 days old (OK)
+#
+# Overall Status: FRESH
+```
+
+### 6.3 Audit Trail
+
+All import operations are logged:
+
+```bash
+# View import history
+stellaops vexlens import history --limit 10
+
+# Output:
+# Import History
+# --------------
+# 2025-12-06 08:00: vexlens-bundle-2025-12-06 (merge, 50000 statements)
+# 2025-11-29 08:00: vexlens-bundle-2025-11-29 (incremental, 12000 statements)
+# ...
+```
+
+---
+
+## 7) Degraded Mode Operation
+
+### 7.1 Degradation Matrix
+
+| Component | Degradation | Impact | Mitigation |
+|-----------|-------------|--------|------------|
+| Stale VEX data | >7 days old | Lower accuracy | Schedule bundle update |
+| Missing issuers | Unknown issuer | Lower trust scores | Add issuer to directory |
+| No projections | Cold start | Slower first queries | Pre-compute on import |
+| Time drift | >24 hours | Staleness warnings | Update time anchor |
+
+### 7.2 Emergency Recovery
+
+If bundle import fails:
+
+```bash
+# Check bundle integrity
+stellaops vexlens import verify --bundle /import/bundle --verbose
+
+# Attempt partial import
+stellaops vexlens import --bundle /import/bundle --skip-corrupted
+
+# Rollback to previous state
+stellaops vexlens import rollback --to vexlens-bundle-2025-11-29
+```
+
+---
+
+## 8) Bundle Management
+
+### 8.1 Retention Policy
+
+```yaml
+vexlens:
+  bundles:
+    # Keep last N bundles
+    retentionCount: 5
+    # Minimum age before deletion
+    minimumAgeDays: 30
+    # Archive location
+    archivePath: /archive/vexlens-bundles
+```
+
+### 8.2 Storage Requirements
+
+| Data Type | Typical Size | Compression Ratio |
+|-----------|--------------|-------------------|
+| Issuers | 1-5 MB | 5:1 |
+| Statements | 100-500 MB | 10:1 |
+| Projections | 50-200 MB | 8:1 |
+| **Total Bundle** | **150-700 MB** | **8:1** |
+
+### 8.3 Bundle Cleanup
+
+```bash
+# Clean old bundles
+stellaops vexlens bundles cleanup --keep 5
+
+# Archive bundles older than 30 days
+stellaops vexlens bundles archive --older-than 30d --to /archive
+```
+
+---
+
+## 9) Security Considerations
+
+### 9.1 Bundle Signing
+
+All bundles should be signed before transfer:
+
+```bash
+# Verify signature chain
+stellaops vexlens import verify-chain \
+  --bundle /import/bundle \
+  --trust-root /etc/vexlens/root-ca.pem
+```
+
+### 9.2 Transfer Security
+
+1. Use encrypted removable media
+2. Maintain custody chain documentation
+3. Verify checksums at each transfer point
+4. Log all bundle operations
+
+### 9.3 Access Control
+
+```yaml
+vexlens:
+  security:
+    # Require authentication for import
+    importRequiresAuth: true
+    # Allowed import roles
+    importRoles: [vexlens.admin, vexlens.operator]
+    # Audit all imports
+    auditImports: true
+```
+
+---
+
+## 10) Troubleshooting
+
+### 10.1 Common Issues
+
+| Issue | Cause | Resolution |
+|-------|-------|------------|
+| Import fails | Corrupted bundle | Re-export from source |
+| Signature invalid | Wrong trust root | Update trust anchors |
+| Time anchor expired | Stale time anchor | Generate new anchor |
+| Missing issuers | Incomplete export | Include issuers in export |
+
+### 10.2 Diagnostic Commands
+
+```bash
+# Verify bundle contents
+stellaops vexlens bundle inspect /import/bundle
+
+# Check import readiness
+stellaops vexlens import preflight --bundle /import/bundle
+
+# Generate diagnostic report
+stellaops vexlens diagnostics --output /tmp/diag.json
+```

+# Mock Dev Release Pipeline
+
+Purpose: provide a minimal CI artifact so deploy tasks can progress with placeholder digests until real releases land.
+
+What it does:
+- Packages `deploy/releases/2025.09-mock-dev.yaml` and `deploy/downloads/manifest.json` into `out/mock-release/mock-dev-release.tgz`.
+- Uploads the tarball as a CI artifact (`mock-dev-release`) for downstream consumers (deploy packaging, docs snapshots, local testing).
+
+How to run locally:
+```bash
+mkdir -p out/mock-release
+cp deploy/releases/2025.09-mock-dev.yaml out/mock-release/
+cp deploy/downloads/manifest.json out/mock-release/
+tar -czf out/mock-release/mock-dev-release.tgz -C out/mock-release .
+```
+
+CI entrypoint:
+- Workflow: `.gitea/workflows/mock-dev-release.yml`
+- Triggers: push to mock manifest/downloads files or manual `workflow_dispatch`.
+
+Notes:
+- Artefacts are **development-only**; replace with real digests as soon as upstream releases publish.
+- Keep the mock manifest and downloads JSON deterministic to avoid artifact churn.***
