+```
+
+## Setup
+
+### 1. Enable Federation
+
+Configure federation in `concelier.yaml`:
+
+```yaml
+Federation:
+  Enabled: true
+  SiteId: "site-us-west-1"  # Unique identifier for this site
+  DefaultCompressionLevel: 3
+  DefaultMaxItems: 10000
+  RequireSignature: true
+
+FederationImport:
+  AllowedSites:
+    - "site-us-east-1"
+    - "site-eu-central-1"
+  MaxBundleSizeBytes: 104857600  # 100 MB
+  SkipSignatureOnTrustedSites: false
+```
+
+### 2. Configure Site Policies
+
+Create site policies for each trusted federation partner:
+
+```bash
+# Add trusted site
+stella feedser sites add site-us-east-1 \
+  --display-name "US East Production" \
+  --enabled
+
+# Configure policy
+stella feedser sites policy site-us-east-1 \
+  --max-bundle-size 100MB \
+  --allowed-sources nvd,ghsa,debian
+```
+
+### 3. Generate Signing Keys
+
+For signed bundles, configure Authority keys:
+
+```bash
+# Generate federation signing key
+stella authority keys generate \
+  --name federation-signer \
+  --algorithm ES256 \
+  --purpose federation
+
+# Export public key for distribution
+stella authority keys export federation-signer --public
+```
+
+## Import Operations
+
+### API Import
+
+```
+POST /api/v1/federation/import
+Content-Type: application/zstd
+```
+
+**Query Parameters:**
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `dry_run` | bool | false | Validate without importing |
+| `skip_signature` | bool | false | Skip signature verification (requires trust) |
+| `on_conflict` | enum | prefer_remote | `prefer_remote`, `prefer_local`, `fail` |
+| `force` | bool | false | Import even if cursor is not after current |
+
+**Response:**
+
+```json
+{
+  "success": true,
+  "bundle_hash": "sha256:a1b2c3...",
+  "imported_cursor": "2025-01-15T10:30:00.000Z#0042",
+  "counts": {
+    "canonical_created": 100,
+    "canonical_updated": 25,
+    "canonical_skipped": 10,
+    "edges_added": 200,
+    "deletions_processed": 5
+  },
+  "conflicts": [],
+  "duration_ms": 1234
+}
+```
+
+### CLI Import
+
+```bash
+# Import from file
+stella feedser bundle import ./bundle.zst
+
+# Import with dry run
+stella feedser bundle import ./bundle.zst --dry-run
+
+# Import from stdin (for pipes)
+cat bundle.zst | stella feedser bundle import -
+
+# Import without signature verification (testing only)
+stella feedser bundle import ./bundle.zst --skip-signature
+
+# Force import (override cursor check)
+stella feedser bundle import ./bundle.zst --force
+```
+
+### Conflict Resolution
+
+When conflicts occur between local and remote values:
+
+| Strategy | Behavior |
+|----------|----------|
+| `prefer_remote` | Remote value wins (default) |
+| `prefer_local` | Local value preserved |
+| `fail` | Abort import on first conflict |
+
+Conflicts are logged with full details:
+
+```json
+{
+  "merge_hash": "sha256:abc...",
+  "field": "severity",
+  "local_value": "high",
+  "remote_value": "critical",
+  "resolution": "prefer_remote"
+}
+```
+
+## Site Management
+
+### List Sites
+
+```bash
+stella feedser sites list
+```
+
+Output:
+```
+SITE ID                    STATUS    LAST SYNC            CURSOR

+site-asia-pacific-1        disabled  never                -
+```
+
+### View Site History
+
+```bash
+stella feedser sites history site-us-east-1 --limit 10
+```
+
+### Update Site Policy
+
+```bash
+stella feedser sites policy site-us-east-1 \
+  --enabled false  # Disable imports from this site
+```
+
+## Air-Gap Operations
+
+For sites without network connectivity:
+
+### Export for Transfer
+
+```bash
+# On connected site
+stella feedser bundle export \
+  -c "2025-01-14T00:00:00Z#0000" \
+  -o ./delta-2025-01-15.zst
+
+# Transfer via USB/secure media
+```
+
+### Import on Air-Gap Site
+
+```bash
+# On air-gapped site
+stella feedser bundle import ./delta-2025-01-15.zst
+
+# Verify import
+stella feedser sites list
+```
+
+### Full Sync Workflow
+
+1. **Initial Sync:**
+   ```bash
+   # Export full dataset
+   stella feedser bundle export -o ./full-sync.zst
+   ```
+
+2. **Transfer to air-gap site**
+
+3. **Import on air-gap:**
+   ```bash
+   stella feedser bundle import ./full-sync.zst
+   ```
+
+4. **Subsequent Delta Syncs:**
+   ```bash
+   # Get current cursor from air-gap site
+   stella feedser sites list  # Note the cursor
+
+   # On connected site, export delta
+   stella feedser bundle export -c "{cursor}" -o ./delta.zst
+
+   # Transfer and import on air-gap
+   ```
+
+## Verification
+
+### Validate Bundle Without Import
+
+```bash
+stella feedser bundle validate ./bundle.zst
+```
+
+Output:
+```
+Bundle: bundle.zst
+  Version: feedser-bundle/1.0
+  Site: site-us-east-1
+  Cursor: 2025-01-15T10:30:00.000Z#0042
+
+Counts:
+  Canonicals: 1,234
+  Edges: 3,456
+  Deletions: 12
+  Total: 4,702
+
+Verification:
+  Hash: ✓ Valid
+  Signature: ✓ Valid (key: sha256:abc...)
+  Format: ✓ Valid
+
+Ready for import.
+```
+
+### Preview Import Impact
+
+```bash
+stella feedser bundle import ./bundle.zst --dry-run --json
+```
+
+## Monitoring
+
+### Sync Status Endpoint
+
+```
+GET /api/v1/federation/sync/status
+```
+
+Response:
+```json
+{
+  "sites": [
+    {
+      "site_id": "site-us-east-1",
+      "enabled": true,
+      "last_sync_at": "2025-01-15T10:30:00Z",
+      "last_cursor": "2025-01-15T10:30:00.000Z#0042",
+      "bundles_imported": 156,
+      "total_items_imported": 45678
+    }
+  ],
+  "local_cursor": "2025-01-15T10:35:00.000Z#0044"
+}
+```
+
+### Event Stream
+
+Import events are published to the `canonical-imported` stream:
+
+```json
+{
+  "canonical_id": "uuid",
+  "cve": "CVE-2024-1234",
+  "affects_key": "pkg:npm/express@4.0.0",
+  "merge_hash": "sha256:...",
+  "action": "Created",
+  "bundle_hash": "sha256:...",
+  "site_id": "site-us-east-1",
+  "imported_at": "2025-01-15T10:30:15Z"
+}
+```
+
+### Cache Invalidation
+
+After import, cache indexes are automatically updated:
+- PURL index updated for affected packages
+- CVE index updated for vulnerability lookups
+- Existing cache entries invalidated for refresh
+
+## Troubleshooting
+
+### Common Issues
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| "Cursor not after current" | Bundle is stale | Use `--force` or export newer bundle |
+| "Signature verification failed" | Key mismatch | Verify signing key is trusted |
+| "Site not allowed" | Policy restriction | Add site to `AllowedSites` config |
+| "Bundle too large" | Size limit exceeded | Increase `MaxBundleSizeBytes` or export smaller delta |
+
+### Debug Logging
+
+Enable verbose logging for federation operations:
+
+```yaml
+Logging:
+  LogLevel:
+    StellaOps.Concelier.Federation: Debug
+```
+
+### Verify Sync State
+
+```bash
+# Check local vs remote cursor
+stella feedser sites status site-us-east-1
+
+# List recent imports
+stella feedser sites history site-us-east-1 --limit 5
+
+# Verify specific canonical was imported
+stella feedser canonical get sha256:mergehash...
+```
+
+## Best Practices
+
+1. **Regular Sync Schedule:** Configure automated delta exports/imports on a schedule (e.g., hourly)
+
+2. **Monitor Cursor Drift:** Alert if cursor falls too far behind
+
+3. **Verify Signatures:** Only disable signature verification in development
+
+4. **Size Bundles Appropriately:** For large deltas, split into multiple bundles
+
+5. **Test Import Before Production:** Use `--dry-run` to validate bundles
+
+6. **Maintain Key Trust:** Regularly rotate and verify federation signing keys
+
+7. **Document Site Policies:** Keep a registry of trusted sites and their policies

+# Federation Setup and Operations Guide
+
+This guide covers the setup and operation of StellaOps federation for multi-site vulnerability data synchronization.
+
+## Overview
+
+Federation enables secure, cursor-based synchronization of canonical vulnerability advisories between StellaOps sites. It supports:
+
+- **Delta exports**: Only changed records since the last cursor are included
+- **Air-gap transfers**: Bundles can be written to files for offline transfer
+- **Multi-site topology**: Multiple sites can synchronize independently
+- **Cryptographic verification**: DSSE signatures ensure bundle authenticity
+
+## Architecture
+
+```
+┌─────────────┐     ┌─────────────┐     ┌─────────────┐
+│   Site A    │────▶│   Bundle    │────▶│   Site B    │
+│  (Export)   │     │   (.zst)    │     │  (Import)   │
+└─────────────┘     └─────────────┘     └─────────────┘
+                          │
+                          ▼
+                    ┌───────────┐
+                    │  Site C   │
+                    │ (Import)  │
+                    └───────────┘
+```
+
+## Bundle Format
+
+Federation bundles are ZST-compressed TAR archives containing:
+
+| File | Description |
+|------|-------------|
+| `MANIFEST.json` | Bundle metadata, cursor, counts, hash |
+| `canonicals.ndjson` | Canonical advisories (one per line) |
+| `edges.ndjson` | Source edges linking advisories to sources |
+| `deletions.ndjson` | Withdrawn/deleted advisory IDs |
+| `SIGNATURE.json` | Optional DSSE signature envelope |
+
+## Configuration
+
+### Export Site Configuration
+
+```yaml
+# concelier.yaml
+federation:
+  enabled: true
+  site_id: "us-west-1"                    # Unique site identifier
+  export:
+    enabled: true

+
+```bash
+# Export full bundle (no cursor = all data)
+feedser bundle export --output bundle.zst
+
+# Export delta since last cursor
+feedser bundle export --since-cursor "2025-01-15T10:00:00Z#0001" --output delta.zst

+```
+
+### Import Operations
+
+```bash
+# Import bundle
+feedser bundle import bundle.zst
+
+# Dry run (validate without importing)
+feedser bundle import bundle.zst --dry-run
+
+# Import from stdin (pipe)
+cat bundle.zst | feedser bundle import -
+
+# Force import (skip cursor validation)
+feedser bundle import bundle.zst --force
+```
+
+### Site Management
+
+```bash
+# List federated sites
+feedser sites list
+
+# Show site details
+feedser sites show us-west-1
+
+# Enable/disable site
+feedser sites enable ap-south-1
+feedser sites disable ap-south-1
+```
+
+## Cursor Format
+
+Cursors use ISO-8601 timestamp with sequence number:
+
+```
+{ISO-8601 timestamp}#{sequence number}
+
+Examples:
+2025-01-15T10:00:00.000Z#0001
+2025-01-15T10:00:00.000Z#0002
+```
+
+- Cursors are site-specific (each site maintains independent cursors)
+- Sequence numbers distinguish concurrent exports
+- Cursors are monotonically increasing within a site
+
+## Air-Gap Transfer Workflow
+
+For environments without network connectivity:
+
+```bash
+# On Source Site (connected to authority)
+feedser bundle export --since-cursor "$LAST_CURSOR" --output /media/usb/bundle.zst
+feedser bundle preview --since-cursor "$LAST_CURSOR" > /media/usb/manifest.txt
+
+# Transfer media to target site...
+
+# On Target Site (air-gapped)
+feedser bundle import /media/usb/bundle.zst --dry-run  # Validate first
+feedser bundle import /media/usb/bundle.zst            # Import
+```
+
+## Multi-Site Synchronization
+
+### Hub-and-Spoke Topology
+
+```
+           ┌─────────────┐
+           │   Hub Site  │
+           │  (Primary)  │
+           └──────┬──────┘
+                  │
+       ┌──────────┼──────────┐
+       ▼          ▼          ▼
+ ┌──────────┐ ┌──────────┐ ┌──────────┐
+ │  Site A  │ │  Site B  │ │  Site C  │
+ │ (Spoke)  │ │ (Spoke)  │ │ (Spoke)  │
+ └──────────┘ └──────────┘ └──────────┘
+```
+
+### Mesh Topology
+
+Each site can import from multiple sources:
+
+```yaml
+federation:
+  import:
+    allowed_sites:
+      - "hub-primary"
+      - "hub-secondary"  # Redundancy
+```
+
+## Merge Behavior
+
+### Conflict Resolution
+
+When importing, conflicts are resolved based on configuration:
+
+| Strategy | Behavior |
+|----------|----------|
+| `prefer_remote` | Remote (bundle) value wins (default) |
+| `prefer_local` | Local value preserved |
+| `fail` | Import aborts on any conflict |
+
+### Merge Actions
+
+| Action | Description |
+|--------|-------------|
+| `Created` | New canonical added |
+| `Updated` | Existing canonical updated |
+| `Skipped` | No change needed (identical) |
+
+## Verification
+
+### Hash Verification
+
+Bundle hash is computed over compressed content:
+
+```
+SHA256(compressed bundle content)
+```
+
+### Signature Verification
+
+DSSE envelope contains:
+
+```json
+{
+  "payloadType": "application/stellaops.federation.bundle+json",
+  "payload": "base64(bundle_hash + site_id + cursor)",
+  "signatures": [
+    {
+      "keyId": "signing-key-001",
+      "algorithm": "ES256",
+      "signature": "base64(signature)"
+    }
+  ]
+}
+```
+
+## Monitoring
+
+### Key Metrics
+
+- `federation_export_duration_seconds` - Export time
+- `federation_import_duration_seconds` - Import time
+- `federation_bundle_size_bytes` - Bundle sizes
+- `federation_items_processed_total` - Items processed by type
+- `federation_conflicts_total` - Merge conflicts encountered
+
+### Health Checks
+
+```bash
+# Check federation status
+curl http://localhost:5000/api/v1/federation/status
+
+# Response
+{
+  "site_id": "us-west-1",
+  "export_enabled": true,
+  "import_enabled": true,
+  "last_export": "2025-01-15T10:00:00Z",
+  "last_import": "2025-01-15T09:30:00Z",
+  "sites_synced": 2
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Import fails with "cursor validation failed"**
+- Bundle cursor is not after current site cursor
+- Use `--force` to override (not recommended)
+- Check if bundle was already imported
+
+**Signature verification failed**
+- Signing key not trusted on target site
+- Key expired or revoked
+- Use `--skip-signature` for testing only
+
+**Large bundle timeout**
+- Increase `federation.export.timeout`
+- Use smaller `max_items_per_bundle`
+- Stream directly to file
+
+### Debug Logging
+
+```yaml
+logging:
+  level:
+    StellaOps.Concelier.Federation: Debug
+```
+
+## Security Considerations
+
+1. **Never skip signature verification in production**
+2. **Validate allowed_sites whitelist**
+3. **Use TLS for API endpoints**
+4. **Rotate signing keys periodically**
+5. **Audit import events**
+6. **Monitor for duplicate bundle imports**

+# Interest Scoring
+
+Per SPRINT_8200_0013_0002.
+
+## Overview
+
+Interest scoring learns which advisories matter to your organization by analyzing SBOM intersections, reachability data, VEX status, and deployment signals. High-interest advisories are prioritized and cached, while low-interest ones are degraded to lightweight stubs to save resources.
+
+## Score Components
+
+The interest score is computed from weighted factors:
+
+| Factor | Weight | Description |
+|--------|--------|-------------|
+| `in_sbom` | 0.4 | Advisory affects a component in registered SBOMs |
+| `reachable` | 0.25 | Affected code is reachable in call graph |
+| `deployed` | 0.15 | Component is deployed in production |
+| `no_vex_na` | 0.1 | No VEX "not_affected" statement exists |
+| `recent` | 0.1 | Advisory is recent (age decay applied) |
+
+### Score Calculation
+
+```
+score = (in_sbom × 0.4) + (reachable × 0.25) + (deployed × 0.15)
+      + (no_vex_na × 0.1) + (recent × 0.1)
+```
+
+Each factor is binary (0.0 or 1.0), except `recent` which decays over time.
+
+## Configuration
+
+Configure in `concelier.yaml`:
+
+```yaml
+InterestScoring:
+  Enabled: true
+
+  # Factor weights (must sum to 1.0)
+  Weights:
+    InSbom: 0.4
+    Reachable: 0.25
+    Deployed: 0.15
+    NoVexNa: 0.1
+    Recent: 0.1
+
+  # Age decay for recent factor
+  RecentDecay:
+    HalfLifeDays: 90
+    MinScore: 0.1
+
+  # Stub degradation policy
+  Degradation:
+    Enabled: true
+    ThresholdScore: 0.1
+    GracePeriodDays: 30
+    RetainCve: true  # Keep CVE ID even in stub form
+
+  # Recalculation job
+  RecalculationJob:
+    Enabled: true
+    IncrementalIntervalMinutes: 15
+    FullRecalculationHour: 3  # 3 AM daily
+```
+
+## API Endpoints
+
+### Get Score
+
+```
+GET /api/v1/canonical/{id}/score
+```
+
+Response:
+```json
+{
+  "canonical_id": "uuid",
+  "score": 0.85,
+  "tier": "high",
+  "reasons": [
+    { "factor": "in_sbom", "value": 1.0, "weight": 0.4, "contribution": 0.4 },

+  ],
+  "computed_at": "2025-01-15T10:30:00Z",
+  "last_seen_in_build": "uuid"
+}
+```
+
+### Trigger Recalculation (Admin)
+
+```
+POST /api/v1/scores/recalculate
+```
+
+Request:
+```json
+{
+  "mode": "incremental",  // or "full"
+  "canonical_ids": null    // null = all, or specific IDs
+}
+```
+
+Response:
+```json
+{
+  "job_id": "uuid",
+  "mode": "incremental",
+  "canonicals_queued": 1234,
+  "started_at": "2025-01-15T10:30:00Z"
+}
+```
+
+## Score Tiers
+
+| Tier | Score Range | Cache TTL | Behavior |
+|------|-------------|-----------|----------|
+| High | >= 0.7 | 24 hours | Full advisory cached, prioritized in queries |
+| Medium | 0.3 - 0.7 | 4 hours | Full advisory cached |
+| Low | 0.1 - 0.3 | 1 hour | Full advisory, eligible for degradation |
+| Negligible | < 0.1 | none | Degraded to stub after grace period |
+
+## Stub Degradation
+
+Low-interest advisories are degraded to lightweight stubs to save storage:
+
+### Full Advisory vs Stub
+
+| Field | Full | Stub |
+|-------|------|------|
+| id | ✓ | ✓ |
+| cve | ✓ | ✓ |
+| affects_key | ✓ | ✓ |
+| merge_hash | ✓ | ✓ |
+| severity | ✓ | ✓ |
+| title | ✓ | ✗ |
+| summary | ✓ | ✗ |
+| references | ✓ | ✗ |
+| weaknesses | ✓ | ✗ |
+| source_edges | ✓ | ✗ |
+
+### Restoration
+
+Stubs are restored to full advisories when:
+- Interest score increases above threshold
+- Advisory is directly queried by ID
+- Advisory appears in scan results
+
+```csharp
+// Automatic restoration
+await scoringService.RestoreFromStubAsync(canonicalId, ct);
+```
+
+## Integration Points
+
+### SBOM Registration
+
+When an SBOM is registered, interest scores are updated:
+
+```
+POST /api/v1/learn/sbom → Triggers score recalculation
+```
+
+### Scan Events
+
+Subscribe to `ScanCompleted` events:
+
+```csharp
+// In event handler
+public async Task HandleScanCompletedAsync(ScanCompletedEvent evt)
+{
+    await sbomService.LearnFromScanAsync(evt.SbomDigest, ct);
+    // This triggers interest score updates for affected advisories
+}
+```
+
+### VEX Updates
+
+VEX imports trigger score recalculation:
+
+```csharp
+// In VEX ingestion pipeline
+await interestService.RecalculateForCanonicalAsync(canonicalId, ct);
+```
+
+## CLI Commands
+
+```bash
+# View score for advisory
+stella scores get sha256:mergehash...
+
+# Trigger recalculation
+stella scores recalculate --mode incremental
+
+# Full recalculation
+stella scores recalculate --mode full
+
+# List high-interest advisories
+stella scores list --tier high --limit 100
+
+# Force restore from stub
+stella scores restore sha256:mergehash...
+```
+
+## Monitoring
+
+### Metrics
+
+| Metric | Type | Description |
+|--------|------|-------------|
+| `interest_score_computed_total` | Counter | Scores computed |
+| `interest_score_distribution` | Histogram | Score distribution |
+| `interest_stubs_created_total` | Counter | Advisories degraded to stubs |
+| `interest_stubs_restored_total` | Counter | Stubs restored to full |
+| `interest_job_duration_seconds` | Histogram | Recalculation job duration |
+
+### Alerts
+
+```yaml
+# Example Prometheus alert

+# Valkey Advisory Cache
+
+Per SPRINT_8200_0013_0001.
+
+## Overview
+
+The Valkey Advisory Cache provides sub-20ms read latency for canonical advisory lookups by caching advisory data and maintaining fast-path indexes. The cache integrates with the Concelier CanonicalAdvisoryService as a read-through cache with automatic population and invalidation.
+
+## Architecture

+
+## Key Schema
+
+### Advisory Entry
+
+**Key:** `advisory:{merge_hash}`
+
+**Value:** JSON-serialized `CanonicalAdvisory`
+
+**TTL:** Based on interest score tier
+
+```json
+{
+  "id": "uuid",
+  "cve": "CVE-2024-1234",
+  "affects_key": "pkg:npm/express@4.0.0",
+  "merge_hash": "sha256:a1b2c3...",
+  "severity": "high",
+  "interest_score": 0.85,
+  "title": "...",
+  "updated_at": "2025-01-15T10:30:00Z"
+}
+```
+
+### Hot Set (Sorted Set)
+
+**Key:** `rank:hot`
+
+**Score:** Interest score (0.0 - 1.0)
+
+**Member:** merge_hash
+
+Stores top advisories by interest score for quick access.
+
+### PURL Index (Set)
+
+**Key:** `by:purl:{normalized_purl}`
+
+**Members:** Set of merge_hash values
+
+Maps package URLs to affected advisories.
+
+Example: `by:purl:pkg:npm/express@4.0.0` → `{sha256:a1b2c3..., sha256:d4e5f6...}`
+
+### CVE Index (Set)
+
+**Key:** `by:cve:{cve_id}`
+
+**Members:** Set of merge_hash values
+
+Maps CVE IDs to canonical advisories.
+
+Example: `by:cve:cve-2024-1234` → `{sha256:a1b2c3...}`
+
+## Operations
+
+### Get Advisory
+
+```csharp
+// Service interface
+public interface IAdvisoryCacheService
+{
+    Task<CanonicalAdvisory?> GetAsync(string mergeHash, CancellationToken ct = default);
+    Task SetAsync(CanonicalAdvisory advisory, CancellationToken ct = default);
+    Task InvalidateAsync(string mergeHash, CancellationToken ct = default);
+    Task<IReadOnlyList<CanonicalAdvisory>> GetByPurlAsync(string purl, CancellationToken ct = default);
+    Task<IReadOnlyList<CanonicalAdvisory>> GetHotAsync(int count = 100, CancellationToken ct = default);
+    Task IndexPurlAsync(string purl, string mergeHash, CancellationToken ct = default);
+    Task IndexCveAsync(string cve, string mergeHash, CancellationToken ct = default);
+}
+```
+
+### Read-Through Cache
+
+```
+1. GetAsync(mergeHash) called
+2. Check Valkey: GET advisory:{mergeHash}
+   └─ Hit: deserialize and return
+   └─ Miss: fetch from PostgreSQL, cache result, return
+```
+
+### Cache Population
+
+Advisories are cached when:
+- First read (read-through)
+- Ingested from source connectors
+- Imported from federation bundles
+- Updated by merge operations
+
+### Cache Invalidation
+
+Invalidation occurs when:
+- Advisory is updated (re-merge with new data)
+- Advisory is withdrawn
+- Manual cache flush requested
+
+```csharp
+// Invalidate single advisory
+await cacheService.InvalidateAsync(mergeHash, ct);
+
+// Invalidate multiple (e.g., after bulk import)
+await cacheService.InvalidateManyAsync(mergeHashes, ct);
+```
+
+## TTL Policy
+
+Interest score determines TTL tier:
+
+| Interest Score | TTL | Rationale |
+|----------------|-----|-----------|
+| >= 0.7 (High) | 24 hours | Hot advisories: likely to be queried frequently |
+| 0.3 - 0.7 (Medium) | 4 hours | Moderate interest: balance between freshness and cache hits |
+| < 0.3 (Low) | 1 hour | Low interest: evict quickly to save memory |
+
+TTL is set when advisory is cached:
+
+```csharp
+var ttl = ttlPolicy.GetTtl(advisory.InterestScore);
+await cache.SetAsync(key, advisory, ttl, ct);
+```
+
+## Monitoring

+## Performance
+
+### Benchmarks
+
+| Operation | p50 | p95 | p99 |
+|-----------|-----|-----|-----|
+| GetAsync (hit) | 1.2ms | 3.5ms | 8.0ms |
+| GetAsync (miss + populate) | 12ms | 25ms | 45ms |
+| SetAsync | 1.5ms | 4.0ms | 9.0ms |
+| GetByPurlAsync | 2.5ms | 6.0ms | 15ms |
+| GetHotAsync(100) | 3.0ms | 8.0ms | 18ms |
+
+### Optimization Tips
+
+1. **Connection Pooling:** Use shared multiplexer with `PoolSize: 20`
+
+2. **Pipeline Reads:** For bulk operations, use pipelining:
+   ```csharp
+   var batch = cache.CreateBatch();
+   foreach (var hash in mergeHashes)
+       tasks.Add(batch.GetAsync(hash));
+   batch.Execute();
+   ```
+
+3. **Hot Set Preload:** Run warmup job on startup to preload hot set
+
+4. **Compression:** Enable Valkey LZF compression for large advisories
+
+## Fallback Behavior
+
+When Valkey is unavailable:
+
+1. **FallbackToPostgres: true** (default)
+   - All reads go directly to PostgreSQL
+   - Performance degrades but system remains operational
+   - Reconnection attempts continue in background
+
+2. **FallbackToPostgres: false**
+   - Cache misses return null/empty
+   - Only cached data is accessible
+   - Use for strict latency requirements
+
+## Troubleshooting
+
+### Common Issues
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| High miss rate | Cache cold / insufficient TTL | Run warmup job, increase TTLs |
+| Latency spikes | Connection exhaustion | Increase PoolSize |
+| Memory pressure | Too many cached advisories | Reduce HotSetMaxSize, lower TTLs |
+| Index stale | Invalidation not triggered | Check event handlers, verify IndexPurlAsync calls |
+
+### Debug Commands
+
+```bash
+# Check cache stats
+stella cache stats
+
+# View hot set
+stella cache list-hot --limit 10
+
+# Check specific advisory
+stella cache get sha256:mergehash...
+
+# Flush cache
+stella cache flush --confirm
+
+# Check PURL index
+stella cache lookup-purl pkg:npm/express@4.0.0
+```
+
+### Valkey CLI
+
+```bash
+# Connect to Valkey
+redis-cli -h localhost -p 6379
+
+# Check memory usage
+INFO memory
+
+# List hot set entries
+ZRANGE rank:hot 0 9 WITHSCORES
+
+# Check PURL index
+SMEMBERS by:purl:pkg:npm/express@4.0.0
+
+# Get advisory
+GET advisory:sha256:a1b2c3...

+# SBOM Learning API
+
+Per SPRINT_8200_0013_0003.
+
+## Overview
+
+The SBOM Learning API enables Concelier to learn which advisories are relevant to your organization by registering SBOMs from scanned images. When an SBOM is registered, Concelier matches its components against the canonical advisory database and updates interest scores accordingly.
+

+
+## Matching Algorithm
+
+### PURL Matching
+
+1. **Exact Match:** `pkg:npm/express@4.17.1` matches advisories affecting exactly that version
+2. **Range Match:** Uses semantic version ranges from advisory affects_key
+3. **Namespace Normalization:** `@scope/pkg` normalized for comparison
+
+### CPE Matching
+
+For OS packages (rpm, deb):
+
+1. Extract CPE from SBOM
+2. Match against advisory CPE patterns
+3. Apply distro-specific version logic (NEVRA/EVR)
+
+### Reachability Integration
+
+When `include_reachability=true`:
+
+1. Query Scanner call graph data for matched components
+2. Mark `is_reachable` based on path from entry point
+3. Factor into interest score calculation
+
+## Events
+
+### SbomLearned
+
+Published when SBOM is registered:
+
+```json
+{
+  "event_type": "sbom_learned",
+  "sbom_id": "uuid",
+  "sbom_digest": "sha256:...",
+  "artifact_id": "sha256:...",
+  "component_count": 234,
+  "matched_advisory_count": 15,
+  "timestamp": "2025-01-15T10:30:00Z"
+}
+```
+
+### ScoresUpdated
+
+Published after batch score update:
+
+```json
+{
+  "event_type": "scores_updated",
+  "trigger": "sbom_registration",
+  "sbom_digest": "sha256:...",
+  "advisories_updated": 15,
+  "timestamp": "2025-01-15T10:30:05Z"
+}
+```

+| Watchlist | 0-39 | Gray (`#6B7280`) | Low - Monitor for changes |
+
+## Evidence Flags
+
+Findings can have special flags indicating evidence quality:
+
+| Flag | Icon | Color | Description |
+|------|------|-------|-------------|
+| `live-signal` | Signal wave | Green | Active runtime signals detected |
+| `proven-path` | Checkmark | Blue | Verified reachability path confirmed |
+| `vendor-na` | Strikethrough | Gray | Vendor marked as not affected |

+}
+```
+
+## Bucket Selection
+
+### Select All in Bucket
+Click "Select All" on a bucket card to select all findings in that bucket.
+
+### Toggle Bucket
+Clicking "Select All" when all bucket items are selected will deselect them.
+
+### Partial Selection
+When some items in a bucket are selected, the button shows a partial indicator.
+
+## Action Descriptions
+
+| Action | Icon | Description |
+|--------|------|-------------|
+| Acknowledge | Checkmark | Mark findings as reviewed |
+| Suppress | Eye-off | Suppress with reason (opens modal) |
+| Assign | User | Assign to team member (opens modal) |
+| Escalate | Alert | Mark for urgent attention |
+
+## Undo Capability
+
+The component maintains an undo stack for recent actions:
+- Up to 5 operations stored
+- Undo restores previous selection
+- Toast shows "Undo" button after action
+
+## Accessibility
+
+- Bucket summary has `aria-label="Findings by priority"`
+- Select All buttons have `aria-pressed` state
+- Action bar has `role="toolbar"`
+- Progress overlay announces to screen readers
+- Modals trap focus and support Escape to close
+- Action buttons have descriptive labels
+
+## Keyboard Navigation
+
+| Key | Action |
+|-----|--------|
+| Tab | Navigate between elements |
+| Enter/Space | Activate buttons |
+| Escape | Close modals |
+
+## Styling
+
+```css
+app-bulk-triage-view {
+  --bucket-card-padding: 16px;
+  --bucket-card-radius: 8px;
+  --action-bar-bg: #f9fafb;

+.bucket-card.investigate { --bucket-color: #2563EB; }
+.bucket-card.watchlist { --bucket-color: #6B7280; }
+```
+
+## Responsive Behavior
+
+| Breakpoint | Layout |
+|------------|--------|
+| > 640px | 4 bucket cards in row |
+| <= 640px | 2x2 grid, action labels hidden |

+
+## Accessibility Notes
+
+- All color combinations meet WCAG 2.1 AA contrast requirements (4.5:1 for text)
+- Bucket colors use both color and position/labels for identification
+- Flag badges use icons in addition to colors
+- Focus states use high-contrast ring colors

+# FindingsListComponent
+
+Comprehensive findings list with Evidence-Weighted Score (EWS) integration, filtering, and bulk selection.
+
+## Overview
+
+The `FindingsListComponent` displays a sortable, filterable table of vulnerability findings with integrated score loading and display.
+
+## Selector
+
+```html
+<app-findings-list />
+```
+
+## Inputs
+
+| Input | Type | Default | Description |
+|-------|------|---------|-------------|
+| `findings` | `Finding[]` | `[]` | Array of findings to display |
+| `autoLoadScores` | `boolean` | `true` | Auto-fetch scores when findings change |
+
+## Outputs
+
+| Output | Type | Description |
+|--------|------|-------------|
+| `findingSelect` | `EventEmitter<ScoredFinding>` | Emits when a finding row is clicked |
+| `selectionChange` | `EventEmitter<string[]>` | Emits finding IDs when selection changes |
+
+## Data Structures
+
+### Finding
+
+```typescript
+interface Finding {
+  id: string;               // Unique finding ID
+  advisoryId: string;       // CVE/GHSA ID
+  packageName: string;
+  packageVersion: string;
+  severity: 'critical' | 'high' | 'medium' | 'low';
+  status: 'open' | 'in_progress' | 'fixed' | 'excepted';
+  publishedAt?: string;     // ISO 8601
+}
+```
+
+### ScoredFinding
+
+```typescript
+interface ScoredFinding extends Finding {
+  score?: EvidenceWeightedScoreResult;
+  scoreLoading: boolean;
+}
+```
+
+## Table Columns
+
+| Column | Description | Sortable |
+|--------|-------------|----------|
+| Checkbox | Bulk selection | No |
+| Score | EWS score pill with flags | Yes |
+| Advisory | CVE/GHSA identifier | Yes |
+| Package | Package name and version | Yes |
+| Severity | CVSS severity level | Yes |
+| Status | Finding status | Yes |
+
+## Features
+
+### Score Loading
+When `autoLoadScores` is true, scores are fetched automatically via the `SCORING_API` injection token.
+
+### Bucket Filtering
+Filter findings by priority bucket using the chip filters:
+- All (default)
+- Act Now (90-100)
+- Schedule Next (70-89)
+- Investigate (40-69)
+- Watchlist (0-39)
+
+### Flag Filtering
+Filter by active score flags:
+- Live Signal
+- Proven Path
+- Vendor N/A
+- Speculative
+
+### Search
+Text search across advisory ID and package name.
+
+### Sorting
+Click column headers to sort. Click again to reverse order.
+
+### Bulk Selection
+- Click checkboxes to select individual findings
+- Use "Select All" to select visible findings
+- Selection persists across filter changes
+
+## Usage Examples
+
+### Basic Usage
+
+```html
+<app-findings-list
+  [findings]="findings"
+  (findingSelect)="openFinding($event)"
+/>
+```
+
+### Without Auto-Loading Scores
+
+```html
+<app-findings-list
+  [findings]="findings"
+  [autoLoadScores]="false"
+/>
+```
+
+### With Selection Handling
+
+```html
+<app-findings-list
+  [findings]="findings"
+  [autoLoadScores]="true"
+  (selectionChange)="onSelectionChange($event)"
+/>
+
+<div class="bulk-actions" *ngIf="selectedIds.length > 0">
+  <button (click)="acknowledgeSelected()">
+    Acknowledge ({{ selectedIds.length }})
+  </button>
+</div>
+```
+
+```typescript
+selectedIds: string[] = [];
+
+onSelectionChange(ids: string[]): void {
+  this.selectedIds = ids;
+}
+```
+
+### Full Feature Example
+
+```typescript
+@Component({
+  selector: 'app-vulnerability-dashboard',
+  template: `
+    <div class="dashboard">
+      <h1>Vulnerabilities</h1>
+
+      <app-findings-list
+        [findings]="findings()"
+        [autoLoadScores]="true"
+        (findingSelect)="openFindingDetail($event)"
+        (selectionChange)="updateSelection($event)"
+      />
+
+      @if (selectedFinding()) {
+        <app-finding-detail-panel
+          [finding]="selectedFinding()"
+          (close)="closeFindingDetail()"
+        />
+      }
+    </div>
+  `
+})
+export class VulnerabilityDashboardComponent {
+  findings = signal<Finding[]>([]);
+  selectedFinding = signal<ScoredFinding | null>(null);
+  selectedIds = signal<string[]>([]);
+
+  constructor(private findingsService: FindingsService) {
+    this.loadFindings();
+  }
+
+  async loadFindings(): Promise<void> {
+    this.findings.set(await this.findingsService.getFindings());
+  }
+
+  openFindingDetail(finding: ScoredFinding): void {
+    this.selectedFinding.set(finding);
+  }
+
+  closeFindingDetail(): void {
+    this.selectedFinding.set(null);
+  }
+
+  updateSelection(ids: string[]): void {
+    this.selectedIds.set(ids);
+  }
+}
+```
+
+## Dependency Injection
+
+The component requires a `SCORING_API` provider:
+
+```typescript
+import { SCORING_API, ScoringApiService } from '@app/core/services/scoring.service';
+
+@NgModule({
+  providers: [
+    { provide: SCORING_API, useClass: ScoringApiService }
+  ]
+})
+export class AppModule {}
+```
+
+### Mock API for Testing
+
+```typescript
+import { MockScoringApi } from '@app/core/services/scoring.service';
+
+TestBed.configureTestingModule({
+  providers: [
+    { provide: SCORING_API, useClass: MockScoringApi }
+  ]
+});
+```
+
+## Empty States
+
+### No Findings
+
+```html
+<!-- Displays: "No findings to display" -->
+<app-findings-list [findings]="[]" />
+```
+
+### No Matches
+
+When filters result in no matches:
+```html
+<!-- Displays: "No findings match the current filters" -->
+```
+
+## Accessibility
+
+- Proper table semantics with `<table>`, `<thead>`, `<tbody>`
+- Sortable columns use `aria-sort`
+- Checkboxes have accessible labels
+- Filter chips are keyboard navigable
+- Focus management on filter/sort changes
+- Screen reader announces result counts
+
+## Styling
+
+```css
+app-findings-list {
+  --table-header-bg: #f9fafb;
+  --table-border-color: #e5e7eb;
+  --table-row-hover: #f3f4f6;
+  --table-row-selected: #eff6ff;
+}
+```

+
+## Flag Significance
+
+### live-signal (Green - High Confidence)
+Indicates the vulnerability affects code that is actively being executed in production. This is the highest confidence indicator and typically elevates priority.
+
+**Sources:**
+- Runtime telemetry from deployed containers
+- Function call traces
+- Code coverage data from production
+
+### proven-path (Blue - Confirmed)
+A verified call path from application entry points to the vulnerable function has been confirmed through static or dynamic analysis.
+
+**Sources:**
+- Static reachability analysis
+- Dynamic call graph analysis
+- Fuzzing results
+
+### vendor-na (Gray - Vendor Override)
+The software vendor has issued a VEX statement indicating this vulnerability does not affect their product configuration or version.
+
+**Sources:**
+- Vendor VEX documents
+- CSAF advisories
+- Distro security teams
+
+### speculative (Orange - Unconfirmed)
+The evidence for this vulnerability is speculative or based on incomplete analysis. Score caps are typically applied.
+
+**Sources:**
+- Incomplete static analysis
+- Heuristic-based detection
+- Unverified reports
+
+## Accessibility
+
+- Uses `role="img"` with descriptive `aria-label`
+- Tooltip shown on focus for keyboard users
+- Icon colors meet WCAG AA contrast requirements

+
+## Styling
+
+```css
+stella-score-badge {
+  --badge-font-size: 12px;
+  --badge-padding: 4px 8px;
+  --badge-border-radius: 4px;
+}
+```
+
+### Live Signal Animation
+
+The live-signal badge features a subtle pulse animation to draw attention:
+
+```css
+@keyframes pulse {
+  0%, 100% { opacity: 1; }
+  50% { opacity: 0.7; }
+}
+
+.live-signal-badge {
