 This repository hosts the StellaOps Concelier service, its plug-in ecosystem, and the
 first-party CLI (`stellaops-cli`). Concelier ingests vulnerability advisories from
-authoritative sources, stores them in MongoDB, and exports deterministic JSON and
+authoritative sources, stores them in PostgreSQL, and exports deterministic JSON and
 Trivy DB artefacts. The CLI drives scanner distribution, scan execution, and job

+# Proof Chain Benchmark Suite
+
+This benchmark suite measures performance of proof chain operations as specified in the Proof and Evidence Chain Technical Reference advisory.
+
+## Overview
+
+The benchmarks focus on critical performance paths:
+
+1. **Content-Addressed ID Generation** - SHA-256 hashing and ID formatting
+2. **Proof Spine Assembly** - Merkle tree construction and deterministic bundling
+3. **Verification Pipeline** - End-to-end verification flow
+4. **Key Rotation Operations** - Trust anchor lookups and key validation
+
+## Running Benchmarks
+
+### Prerequisites
+
+- .NET 10 SDK
+- PostgreSQL 16+ (for database benchmarks)
+- BenchmarkDotNet 0.14+
+
+### Quick Start
+
+```bash
+# Run all benchmarks
+cd bench/proof-chain
+dotnet run -c Release
+
+# Run specific benchmark class
+dotnet run -c Release -- --filter *IdGeneration*
+
+# Export results
+dotnet run -c Release -- --exporters json markdown
+```
+
+## Benchmark Categories
+
+### 1. ID Generation Benchmarks

+
+## Regression Detection
+
+Benchmarks are run as part of CI with regression detection:
+
+```yaml
+# .gitea/workflows/benchmark.yaml
+name: Benchmark
+on:
+  pull_request:
+    paths:
+      - 'src/Attestor/**'
+      - 'src/Signer/**'
+
+jobs:
+  benchmark:
+    runs-on: self-hosted
+    steps:
+      - uses: actions/checkout@v4
+      - name: Run benchmarks
+        run: |
+          cd bench/proof-chain
+          dotnet run -c Release -- --exporters json
+      - name: Compare with baseline
+        run: |
+          python3 tools/compare-benchmarks.py \
+            --baseline baselines/proof-chain.json \
+            --current BenchmarkDotNet.Artifacts/results/*.json \
+            --threshold 10
+```
+
+Regressions > 10% will fail the PR check.
+
+## Adding New Benchmarks
+
+1. Create benchmark class in `bench/proof-chain/Benchmarks/`
+2. Follow naming convention: `{Feature}Benchmarks.cs`
+3. Add `[MemoryDiagnoser]` attribute for allocation tracking
+4. Include baseline expectations in XML comments
+5. Update baseline after significant changes:
+   ```bash
+   dotnet run -c Release -- --exporters json
+   cp BenchmarkDotNet.Artifacts/results/*.json baselines/
+   ```
+
+## Performance Guidelines
+
+From advisory §14.1:
+
+| Operation | P50 Target | P99 Target |
+|-----------|------------|------------|
+| Proof Bundle creation | 50ms | 200ms |
+| Proof Bundle verification | 100ms | 500ms |
+| SBOM verification (complete) | 500ms | 2s |

-   into a directory that is already on the default library path, or export the
-   `LD_LIBRARY_PATH` value shown above before invoking `dotnet test`.

+# EPSS Air-Gapped Bundles Guide
+
+## Overview
+
+This guide describes how to create, distribute, and import EPSS (Exploit Prediction Scoring System) data bundles for air-gapped StellaOps deployments. EPSS bundles enable offline vulnerability risk scoring with the same probabilistic threat intelligence available to online deployments.
+
+**Key Concepts**:
+- **Risk Bundle**: Aggregated security data (EPSS + KEV + advisories) for offline import
+- **EPSS Snapshot**: Single-day EPSS scores for all CVEs (~300k rows)
+- **Staleness Threshold**: How old EPSS data can be before fallback to CVSS-only
+- **Deterministic Import**: Same bundle imported twice yields identical database state

+## Creating EPSS Bundles
+
+### Prerequisites
+
+**Build System Requirements**:
+- Internet access (for fetching FIRST.org data)
+- StellaOps Bundler CLI: `stellaops-bundler`
+- ZSTD compression: `zstd` (v1.5+)
+- Python 3.10+ (for verification scripts)
+
+**Permissions**:
+- Read access to FIRST.org EPSS API/CSV endpoints
+- Write access to bundle staging directory
+- (Optional) Signing key for DSSE signatures
+
+### Daily Bundle Creation (Automated)
+
+**Recommended Schedule**: Daily at 01:00 UTC (after FIRST publishes at ~00:00 UTC)
+
+**Script**: `scripts/create-risk-bundle.sh`
+
+```bash
+#!/bin/bash
+set -euo pipefail

+```
+
+---
+
+## Distributing Bundles
+
+### Transfer Methods
+
+#### 1. Physical Media (Highest Security)
+
+```bash
+# Copy to USB drive
+cp /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz /media/usb/stellaops/
+
+# Verify checksum
+sha256sum /media/usb/stellaops/risk-bundle-2025-12-17.tar.gz
+```
+
+#### 2. Secure File Transfer (Network Isolation)
+
+```bash
+# SCP over dedicated management network
+scp /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz \
+  admin@airgap-gateway.internal:/incoming/
+
+# Verify after transfer
+ssh admin@airgap-gateway.internal \
+  "sha256sum /incoming/risk-bundle-2025-12-17.tar.gz"
+```
+
+#### 3. Offline Bundle Repository (CD/DVD)
+
+```bash
+# Burn to CD/DVD (for regulated industries)
+growisofs -Z /dev/sr0 \
+  -R -J -joliet-long \
+  -V "StellaOps Risk Bundle 2025-12-17" \
+  /var/stellaops/bundles/risk-bundle-2025-12-17.tar.gz
+
+# Verify disc
+md5sum /dev/sr0 > risk-bundle-2025-12-17.md5
+```
+
+### Storage Recommendations
+
+**Bundle Retention**:
+- **Online bundler**: Keep last 90 days (rolling cleanup)
+- **Air-gapped system**: Keep last 30 days minimum (for rollback)
+
+**Naming Convention**:
+- Pattern: `risk-bundle-YYYY-MM-DD.tar.gz`
+- Example: `risk-bundle-2025-12-17.tar.gz`
+
+**Directory Structure** (air-gapped system):
+```
+/opt/stellaops/bundles/
+├── incoming/               # Transfer staging area
+├── verified/               # Verified, ready to import
+├── imported/               # Successfully imported (archive)
+└── failed/                 # Failed verification/import (quarantine)
+```
+
+---
+
+## Importing Bundles (Air-Gapped System)
+
+### Pre-Import Verification
+
+**Step 1: Transfer to Verified Directory**
+
+```bash
+# Transfer from incoming to verified (manual approval gate)
+sudo mv /opt/stellaops/bundles/incoming/risk-bundle-2025-12-17.tar.gz \
+        /opt/stellaops/bundles/verified/
+```
+
+**Step 2: Verify Bundle Integrity**
+
+```bash
+# Extract bundle
+cd /opt/stellaops/bundles/verified
+tar -xzf risk-bundle-2025-12-17.tar.gz
+
+# Verify checksums
+cd risk-bundle-2025-12-17
+sha256sum -c signatures/bundle.sha256sums
+
+# Expected output:
+# epss/epss_scores-2025-12-17.csv.zst: OK
+# epss/epss_metadata.json: OK
+# kev/kev-catalog.json: OK
+# manifest.json: OK
+```
+
+**Step 3: Verify DSSE Signature (if signed)**
+
+```bash
+stellaops-bundler verify-signature \
+  --manifest manifest.json \
+  --signature signatures/bundle.dsse.json \
+  --trusted-keys /etc/stellaops/trusted-keys.json
+
+# Expected output:
+# ✓ Signature valid
+# ✓ Key ID: stellaops-bundler-2025
+# ✓ Signed at: 2025-12-17T01:05:00Z
+```
+
+### Import Procedure
+
+**Step 4: Import Bundle**
+
+```bash
+# Import using stellaops CLI
+stellaops offline import \
+  --bundle /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+  --verify \
+  --dry-run
+
+# Review dry-run output, then execute
+stellaops offline import \
+  --bundle /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+  --verify
+```
+
+**Import Output**:
+```
+Importing risk bundle: risk-bundle-2025-12-17
+  ✓ Manifest validated
+  ✓ Checksums verified
+  ✓ Signature verified
+
+Importing EPSS data...
+  Model Date: 2025-12-17

+  ✓ epss_current upserted (231,417 rows, 5.2s)
+  ✓ Event emitted: epss.updated
+
+Importing KEV catalog...
+  Known Exploited Count: 1,247
+  ✓ kev_catalog updated
+
+Import completed successfully in 41.2s
+```
+
+**Step 5: Verify Import**
+
+```bash
+# Check EPSS status
+stellaops epss status
+
+# Expected output:
+# EPSS Status:
+#   Latest Model Date: 2025-12-17
+#   Source: bundle://risk-bundle-2025-12-17
+#   CVE Count: 231,417
+#   Staleness: FRESH (0 days)
+#   Import Time: 2025-12-17T10:30:00Z
+
+# Query specific CVE to verify
+stellaops epss get CVE-2024-12345
+
+# Expected output:
+# CVE-2024-12345
+#   Score: 0.42357
+#   Percentile: 88.2th
+#   Model Date: 2025-12-17
+#   Source: bundle://risk-bundle-2025-12-17
+```
+
+**Step 6: Archive Imported Bundle**
+
+```bash
+# Move to imported archive
+sudo mv /opt/stellaops/bundles/verified/risk-bundle-2025-12-17.tar.gz \
+        /opt/stellaops/bundles/imported/

+## Staleness Handling
+
+### Staleness Thresholds
+
+| Days Since Model Date | Status | Action |
+|-----------------------|--------|--------|
+| 0-1 | FRESH | Normal operation |
+| 2-7 | ACCEPTABLE | Continue, low-priority alert |
+| 8-14 | STALE | Alert, plan bundle import |
+| 15+ | VERY_STALE | Fallback to CVSS-only, urgent alert |
+
+### Monitoring Staleness
+
+**SQL Query**:
+```sql
+SELECT * FROM concelier.epss_model_staleness;
+
+-- Output:
+-- latest_model_date | latest_import_at       | days_stale | staleness_status
+-- 2025-12-10        | 2025-12-10 10:30:00+00 | 7          | ACCEPTABLE
+```
+
+**Prometheus Metric**:
+```promql
+epss_model_staleness_days{instance="airgap-prod"}
+
+# Alert rule:
+- alert: EpssDataStale
+  expr: epss_model_staleness_days > 7
+  for: 1h
+  labels:
+    severity: warning
+  annotations:
+    summary: "EPSS data is stale ({{ $value }} days old)"
+```
+
+### Fallback Behavior
+
+When EPSS data is VERY_STALE (>14 days):
+
+**Automatic Fallback**:
+- Scanner: Skip EPSS evidence, log warning
+- Policy: Use CVSS-only scoring (no EPSS bonus)
+- Notifications: Disabled EPSS-based alerts
+- UI: Show staleness banner, disable EPSS filters
+
+**Manual Override** (force continue using stale data):
+```yaml
+# etc/scanner.yaml
+scanner:
+  epss:
+    staleness_policy: continue  # Options: fallback, continue, error
+    max_staleness_days: 30      # Override 14-day default
+```
+
+---
+
+## Troubleshooting
+
+### Bundle Import Failed: Checksum Mismatch
+
+**Symptom**:
+```
+ERROR: Checksum verification failed
+epss/epss_scores-2025-12-17.csv.zst: FAILED
+```
+
+**Diagnosis**:
+1. Verify bundle was not corrupted during transfer:
+   ```bash
+   # Compare with original
+   sha256sum risk-bundle-2025-12-17.tar.gz
+   ```
+
+2. Re-transfer bundle from source
+
+**Resolution**:
+- Delete corrupted bundle: `rm risk-bundle-2025-12-17.tar.gz`
+- Re-download/re-transfer from bundler system
+
+### Bundle Import Failed: Signature Invalid
+
+**Symptom**:
+```
+ERROR: Signature verification failed
+Invalid signature or untrusted key
+```
+
+**Diagnosis**:
+1. Check trusted keys configured:
+   ```bash
+   cat /etc/stellaops/trusted-keys.json
+   ```
+
+2. Verify key ID in bundle signature matches:
+   ```bash
+   jq '.signature.key_id' manifest.json
+   ```
+
+**Resolution**:
+- Update trusted keys file with current bundler public key
+- Or: Skip signature verification (if signatures optional):
+  ```bash
+  stellaops offline import --bundle risk-bundle-2025-12-17.tar.gz --skip-signature-verify
+  ```
+
+### No EPSS Data After Import
+
+**Symptom**:
+- Import succeeded, but `stellaops epss status` shows "No EPSS data"
+
+**Diagnosis**:
+```sql
+-- Check import runs
+SELECT * FROM concelier.epss_import_runs ORDER BY created_at DESC LIMIT 1;
+
+-- Check epss_current count
+SELECT COUNT(*) FROM concelier.epss_current;
+```
+
+**Resolution**:
+1. If import_runs shows FAILED status:
+   - Check error column: `SELECT error FROM concelier.epss_import_runs WHERE status = 'FAILED'`
+   - Re-run import with verbose logging
+
+2. If epss_current is empty:
+   - Manually trigger upsert:
+     ```sql
+     -- Re-run upsert for latest model_date
+     -- (This SQL is safe to re-run)
+     INSERT INTO concelier.epss_current (cve_id, epss_score, percentile, model_date, import_run_id, updated_at)
+     SELECT s.cve_id, s.epss_score, s.percentile, s.model_date, s.import_run_id, NOW()
+     FROM concelier.epss_scores s
+     WHERE s.model_date = (SELECT MAX(model_date) FROM concelier.epss_import_runs WHERE status = 'SUCCEEDED')
+     ON CONFLICT (cve_id) DO UPDATE SET
+       epss_score = EXCLUDED.epss_score,
+       percentile = EXCLUDED.percentile,
+       model_date = EXCLUDED.model_date,
+       import_run_id = EXCLUDED.import_run_id,
+       updated_at = NOW();
+     ```
+
+---
+
+## Best Practices
+
+### 1. Weekly Bundle Import Cadence
+
+**Recommended Schedule**:
+- **Minimum**: Weekly (every Monday)
+- **Preferred**: Bi-weekly (Monday & Thursday)
+- **Ideal**: Daily (if transfer logistics allow)
+
+### 2. Bundle Verification Checklist
+
+Before importing:
+- [ ] Checksum verification passed
+- [ ] Signature verification passed (if signed)
+- [ ] Model date within acceptable staleness window
+- [ ] Disk space available (estimate: 500MB per bundle)
+- [ ] Backup current EPSS data (for rollback)
+
+### 3. Rollback Plan
+
+If new bundle causes issues:
+```bash
+# 1. Identify problematic import_run_id
+SELECT import_run_id, model_date, status
+FROM concelier.epss_import_runs
+ORDER BY created_at DESC LIMIT 5;
+
+# 2. Delete problematic import (cascades to epss_scores, epss_changes)
+DELETE FROM concelier.epss_import_runs
+WHERE import_run_id = '550e8400-...';
+
+# 3. Restore epss_current from previous day
+-- (Upsert from previous model_date as shown in troubleshooting)
+
+# 4. Verify rollback
+stellaops epss status
+```
+
+### 4. Audit Trail
+
+Log all bundle imports for compliance:
+
+**Audit Log Format** (`/var/log/stellaops/bundle-audit.log`):
+```json
+{
+  "timestamp": "2025-12-17T10:30:00Z",
+  "action": "import",
+  "bundle_id": "risk-bundle-2025-12-17",
+  "bundle_sha256": "abc123...",
+  "imported_by": "admin@example.com",
+  "import_run_id": "550e8400-e29b-41d4-a716-446655440000",
+  "result": "SUCCESS",
+  "row_count": 231417,
+  "duration_seconds": 41.2
+}
+```

+- Updated `ImportValidator` to include monotonicity checks, force-activate support (requires reason), and quarantine on validation failures.
+- Added Postgres-backed bundle version tracking in `src/AirGap/StellaOps.AirGap.Storage.Postgres/Repositories/PostgresBundleVersionStore.cs` and registration via `src/AirGap/StellaOps.AirGap.Storage.Postgres/ServiceCollectionExtensions.cs`.
+- Updated tests in `tests/AirGap/StellaOps.AirGap.Importer.Tests` to cover versioning/quarantine and the new import validator behavior.
+
 ## Next implementation hooks
 - Replace placeholder plan with actual DSSE + TUF verifiers; keep step ordering stable.
 - Feed trust roots from sealed-mode config and Evidence Locker bundles (once available) before allowing imports.
 - Record audit trail for each plan step (success/failure) and a Merkle root of staged content.
 
 ## Determinism/air-gap posture
-- No network dependencies; only BCL used.
+- No network dependencies; BCL + `Microsoft.Extensions.*` only.
 - Tests use cached local NuGet feed (`local-nugets/`).
 - Plan steps are ordered list; do not reorder without bumping downstream replay expectations.

+# Offline Bundle Format (.stella.bundle.tgz)
+
+> Sprint: SPRINT_3603_0001_0001  
+> Module: ExportCenter
+
+This document describes the `.stella.bundle.tgz` format for portable, signed, verifiable evidence packages.
+
+## Overview
+
+The offline bundle is a self-contained archive containing all evidence and artifacts needed for offline triage of security findings. Bundles are:
+
+- **Portable**: Single file that can be transferred to air-gapped environments
+- **Signed**: DSSE-signed manifest for authenticity verification
+- **Verifiable**: Content-addressable with SHA-256 hashes for integrity
+- **Complete**: Contains all data needed for offline decision-making
+
+## File Format

+  "hash": "sha256:abc123...",
+  "size": 2048,
+  "content_type": "application/json",
+  "compression": null
+}
+```
+
+## DSSE Signing
+
+Bundles support DSSE (Dead Simple Signing Envelope) signing:
+
+```json
+{
+  "payloadType": "application/vnd.stellaops.bundle.manifest+json",
+  "payload": "<base64-encoded manifest>",
+  "signatures": [
+    {

+      "sig": "<base64-encoded signature>"
+    }
+  ]
+}
+```
+
+## Creation
+
+### API Endpoint
+
+```http
+GET /v1/alerts/{alertId}/bundle
+Authorization: Bearer <token>
+
+Response: application/gzip
+Content-Disposition: attachment; filename="alert-123.stella.bundle.tgz"
+```
+
+### Programmatic
+
+```csharp
+var packager = services.GetRequiredService<IOfflineBundlePackager>();
+
+var result = await packager.CreateBundleAsync(new BundleRequest
+{
+    AlertId = "alert-123",
+    ActorId = "user@example.com",
+    IncludeVexHistory = true,
+    IncludeSbomSlice = true
+});
+
+// result.Content contains the tarball stream
+// result.ManifestHash contains the verification hash
+```
+
+## Verification
+
+### API Endpoint
+
+```http
+POST /v1/alerts/{alertId}/bundle/verify
+Content-Type: application/json
+
+{
+  "bundle_hash": "sha256:abc123...",
+  "signature": "<optional DSSE signature>"
+}
+
+Response:
+{
+  "is_valid": true,
+  "hash_valid": true,
+  "chain_valid": true,
+  "signature_valid": true,
+  "verified_at": "2024-12-15T10:00:00Z"
+}
+```
+
+### Programmatic
+
+```csharp
+var verification = await packager.VerifyBundleAsync(
+    bundlePath: "/path/to/bundle.stella.bundle.tgz",
+    expectedHash: "sha256:abc123...");
+
+if (!verification.IsValid)
+{
+    Console.WriteLine($"Verification failed: {string.Join(", ", verification.Errors)}");
+}
+```
+
+## CLI Usage
+
+```bash
+# Export bundle
+stellaops alert bundle export --alert-id alert-123 --output ./bundles/
+
+# Verify bundle
+stellaops alert bundle verify --file ./bundles/alert-123.stella.bundle.tgz
+
+# Import bundle (air-gapped instance)
+stellaops alert bundle import --file ./bundles/alert-123.stella.bundle.tgz
+```
+
+## Security Considerations
+
+1. **Hash Verification**: Always verify bundle hash before processing
+2. **Signature Validation**: Verify DSSE signature if present
+3. **Content Validation**: Validate JSON schemas after extraction
+4. **Size Limits**: Enforce maximum bundle size limits (default: 100MB)
+5. **Path Traversal**: Tarball extraction must prevent path traversal attacks
+

+# Proof Chain Verification in Air-Gap Mode
+
+> **Version**: 1.0.0  
+> **Last Updated**: 2025-12-17  
+> **Related**: [Proof Chain API](../api/proofs.md), [Key Rotation Runbook](../operations/key-rotation-runbook.md)
+
+This document describes how to verify proof chains in air-gapped (offline) environments where Rekor transparency log access is unavailable.
+
+---
+
+## Overview
+
+Proof chains in StellaOps consist of cryptographically-linked attestations:
+1. **Evidence statements** - Raw vulnerability findings
+2. **Reasoning statements** - Policy evaluation traces
+3. **VEX verdict statements** - Final vulnerability status determinations
+4. **Proof spine** - Merkle tree aggregating all components
+
+In online mode, proof chains include Rekor inclusion proofs for transparency. In air-gap mode, verification proceeds without Rekor but maintains cryptographic integrity.
+
+---
+
+## Verification Levels
+
+### Level 1: Content-Addressed ID Verification
+Verifies that content-addressed IDs match payload hashes.
+
+```bash
+# Verify a proof bundle ID
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --level content-id
+
+# Expected output:
+# ✓ Content-addressed ID verified
+# ✓ Payload hash: sha256:1a2b3c4d...
+```
+
+### Level 2: DSSE Signature Verification
+Verifies DSSE envelope signatures against trust anchors.
+
+```bash
+# Verify signatures with local trust anchors
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --anchor-file /path/to/trust-anchors.json \
+  --level signature
+
+# Expected output:
+# ✓ DSSE signature valid
+# ✓ Signer: key-2025-prod
+# ✓ Trust anchor: 550e8400-e29b-41d4-a716-446655440000
+```
+
+### Level 3: Merkle Path Verification
+Verifies the proof spine merkle tree structure.
+
+```bash
+# Verify merkle paths
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --level merkle
+
+# Expected output:
+# ✓ Merkle root verified
+# ✓ Evidence paths: 3/3 valid
+# ✓ Reasoning path: valid
+# ✓ VEX verdict path: valid
+```
+
+### Level 4: Full Verification (Offline)
+Performs all verification steps except Rekor.
+
+```bash
+# Full offline verification
+stellaops proof verify --offline \
+  --proof-bundle sha256:1a2b3c4d... \
+  --anchor-file /path/to/trust-anchors.json
+
+# Expected output:
+# Proof Chain Verification
+# ═══════════════════════
+# ✓ Content-addressed IDs verified
+# ✓ DSSE signatures verified (3 envelopes)
+# ✓ Merkle paths verified
+# ⊘ Rekor verification skipped (offline mode)
+# 
+# Overall: VERIFIED (offline)
+```
+
+---
+
+## Trust Anchor Distribution
+
+In air-gap environments, trust anchors must be distributed out-of-band.
+
+### Export Trust Anchors
+
+```bash
+# On the online system, export trust anchors
+stellaops anchor export --format json > trust-anchors.json
+
+# Verify export integrity
+sha256sum trust-anchors.json > trust-anchors.sha256
+```
+
+### Trust Anchor File Format
+
+```json
+{
+  "version": "1.0",
+  "exportedAt": "2025-12-17T00:00:00Z",
+  "anchors": [
+    {
+      "trustAnchorId": "550e8400-e29b-41d4-a716-446655440000",
+      "purlPattern": "pkg:*",
+      "allowedKeyids": ["key-2024-prod", "key-2025-prod"],
+      "allowedPredicateTypes": [
+        "evidence.stella/v1",
+        "reasoning.stella/v1",
+        "cdx-vex.stella/v1",
+        "proofspine.stella/v1"
+      ],
+      "revokedKeys": ["key-2023-prod"],
+      "keyMaterial": {
+        "key-2024-prod": {
+          "algorithm": "ECDSA-P256",
+          "publicKey": "-----BEGIN PUBLIC KEY-----\n..."
+        },
+        "key-2025-prod": {
+          "algorithm": "ECDSA-P256",
+          "publicKey": "-----BEGIN PUBLIC KEY-----\n..."
+        }
+      }
+    }
+  ]
+}
+```
+
+### Import Trust Anchors
+
+```bash
+# On the air-gapped system
+stellaops anchor import --file trust-anchors.json
+
+# Verify import
+stellaops anchor list
+```
+
+---
+
+## Proof Bundle Distribution
+
+### Export Proof Bundles
+
+```bash
+# Export a proof bundle for offline transfer
+stellaops proof export \
+  --entry sha256:abc123:pkg:npm/lodash@4.17.21 \
+  --output proof-bundle.zip
+
+# Bundle contents:
+# proof-bundle.zip
+# ├── proof-spine.json        # The proof spine
+# ├── evidence/               # Evidence statements
+# │   ├── sha256_e1.json
+# │   └── sha256_e2.json
+# ├── reasoning.json          # Reasoning statement
+# ├── vex-verdict.json        # VEX verdict statement
+# ├── envelopes/              # DSSE envelopes
+# │   ├── evidence-e1.dsse
+# │   ├── evidence-e2.dsse
+# │   ├── reasoning.dsse
+# │   ├── vex-verdict.dsse
+# │   └── proof-spine.dsse
+# └── VERIFY.md               # Verification instructions
+```
+
+### Verify Exported Bundle
+
+```bash
+# On the air-gapped system
+stellaops proof verify --offline \
+  --bundle-file proof-bundle.zip \
+  --anchor-file trust-anchors.json
+```
+
+---
+
+## Batch Verification
+
+For audits, verify multiple proof bundles efficiently:
+
+```bash
+# Create a verification manifest
+cat > verify-manifest.json << 'EOF'
+{
+  "bundles": [
+    "sha256:1a2b3c4d...",
+    "sha256:5e6f7g8h...",
+    "sha256:9i0j1k2l..."
+  ],
+  "options": {
+    "checkRekor": false,
+    "failFast": false
+  }
+}
+EOF
+
+# Run batch verification
+stellaops proof verify-batch \
+  --manifest verify-manifest.json \
+  --anchor-file trust-anchors.json \
+  --output verification-report.json
+```
+
+### Verification Report Format
+
+```json
+{
+  "verifiedAt": "2025-12-17T10:00:00Z",
+  "mode": "offline",
+  "anchorsUsed": ["550e8400..."],
+  "results": [
+    {
+      "proofBundleId": "sha256:1a2b3c4d...",
+      "verified": true,
+      "checks": {
+        "contentId": true,
+        "signature": true,

+      }
+    }
+  ],
+  "summary": {
+    "total": 3,
+    "verified": 3,
+    "failed": 0,
+    "skipped": 0
+  }
+}
+```
+
+---
+
+## Key Rotation in Air-Gap Mode
+
+When keys are rotated, trust anchor updates must be distributed:
+
+### 1. Export Updated Anchors
+
+```bash
+# On online system after key rotation
+stellaops anchor export --since 2025-01-01 > anchor-update.json
+sha256sum anchor-update.json > anchor-update.sha256
+```
+
+### 2. Verify and Import Update
+
+```bash
+# On air-gapped system
+sha256sum -c anchor-update.sha256
+stellaops anchor import --file anchor-update.json --merge
+
+# Verify key history
+stellaops anchor show --anchor-id 550e8400... --show-history
+```
+
+### 3. Temporal Verification
+
+When verifying old proofs after key rotation:
+
+```bash
+# Verify proof signed with now-revoked key
+stellaops proof verify --offline \
+  --proof-bundle sha256:old-proof... \
+  --anchor-file trust-anchors.json \
+  --at-time "2024-06-15T12:00:00Z"
+
+# The verification uses key validity at the specified time
+```
+
+---
+
+## Manual Verification (No CLI)
+
+For environments without the StellaOps CLI, manual verification is possible:
+
+### 1. Verify Content-Addressed ID
+
+```bash
+# Extract payload from DSSE envelope
+jq -r '.payload' proof-spine.dsse | base64 -d > payload.json
+
+# Compute hash
+sha256sum payload.json
+# Compare with proof bundle ID
+```
+
+### 2. Verify DSSE Signature
+
+```python
+#!/usr/bin/env python3
+import json
+import base64
+from cryptography.hazmat.primitives import hashes
+from cryptography.hazmat.primitives.asymmetric import ec
+from cryptography.hazmat.primitives.serialization import load_pem_public_key
+
+def verify_dsse(envelope_path, public_key_pem):
+    """Verify a DSSE envelope signature."""
+    with open(envelope_path) as f:
+        envelope = json.load(f)
+    
+    payload_type = envelope['payloadType']
+    payload = base64.b64decode(envelope['payload'])
+    
+    # Build PAE (Pre-Authentication Encoding)
+    pae = f"DSSEv1 {len(payload_type)} {payload_type} {len(payload)} ".encode() + payload
+    
+    public_key = load_pem_public_key(public_key_pem.encode())
+    
+    for sig in envelope['signatures']:
+        signature = base64.b64decode(sig['sig'])
+        try:
+            public_key.verify(signature, pae, ec.ECDSA(hashes.SHA256()))
+            print(f"✓ Signature valid for keyid: {sig['keyid']}")
+            return True
+        except Exception as e:
+            print(f"✗ Signature invalid: {e}")
+    
+    return False
+```
+
+### 3. Verify Merkle Path
+
+```python
+#!/usr/bin/env python3
+import json
+import hashlib
+
+def verify_merkle_path(leaf_hash, path, root_hash, leaf_index):
+    """Verify a Merkle inclusion path."""
+    current = bytes.fromhex(leaf_hash)
+    index = leaf_index
+    
+    for sibling in path:
+        sibling_bytes = bytes.fromhex(sibling)
+        if index % 2 == 0:
+            # Current is left child
+            combined = current + sibling_bytes
+        else:
+            # Current is right child
+            combined = sibling_bytes + current
+        current = hashlib.sha256(combined).digest()
+        index //= 2
+    
+    computed_root = current.hex()
+    if computed_root == root_hash:
+        print("✓ Merkle path verified")
+        return True
+    else:
+        print(f"✗ Merkle root mismatch: {computed_root} != {root_hash}")
+        return False
+```
+
+---
+
+## Exit Codes
+
+Offline verification uses the same exit codes as online:
+
+| Code | Meaning | CI/CD Action |
+|------|---------|--------------|
+| 0 | Verification passed | Proceed |
+| 1 | Verification failed | Block |
+| 2 | System error | Retry/investigate |
+
+---
+
+## Troubleshooting
+
+### Missing Trust Anchor
+
+```
+Error: No trust anchor found for keyid "key-2025-prod"
+```
+
+**Solution**: Import updated trust anchors from online system.
+
+### Key Not Valid at Time
+
+```
+Error: Key "key-2024-prod" was revoked at 2024-12-01, before proof signature at 2025-01-15
+```
+
+**Solution**: This indicates the proof was signed after key revocation. Investigate the signature timestamp.
+
+### Merkle Path Invalid
+
+```
+Error: Merkle path verification failed for evidence sha256:e1...
+```
+
+**Solution**: The proof bundle may be corrupted. Re-export from online system.

+# AirGap Quarantine Investigation Runbook
+
+## Purpose
+Quarantine preserves failed bundle imports for offline forensic analysis. It keeps the original bundle and the verification context (reason + logs) so operators can diagnose tampering, trust-root drift, or packaging issues without re-running in an online environment.
+
+## Location & Structure
+Default root: `/updates/quarantine`
+
+Per-tenant layout:
+`/updates/quarantine/<tenantId>/<timestamp>-<reason>-<id>/`
+
+Removal staging:
+`/updates/quarantine/<tenantId>/.removed/<quarantineId>/`
+
+## Files in a quarantine entry
+- `bundle.tar.zst` - the original bundle as provided
+- `manifest.json` - bundle manifest (when available)
+- `verification.log` - validation step output (TUF/DSSE/Merkle/rotation/monotonicity, etc.)
+- `failure-reason.txt` - human-readable failure summary (reason + timestamp + metadata)
+- `quarantine.json` - structured metadata for listing/automation
+
+## Investigation steps (offline)
+1. Identify the tenant and locate the quarantine root on the importer host.
+2. Pick the newest quarantine entry for the tenant (timestamp prefix).
+3. Read `failure-reason.txt` first to capture the top-level reason and metadata.
+4. Review `verification.log` for the precise failing step.
+5. If needed, extract and inspect `bundle.tar.zst` in an isolated workspace (no network).
+6. Decide whether the entry should be retained (for audit) or removed after investigation.
+
+## Removal & Retention
+- Removal requires a human-provided reason (audit trail). Implementations should use the quarantine service’s remove operation which moves entries under `.removed/`.
+- Retention and quota controls are configured via `AirGap:Quarantine` settings (root, TTL, max size); TTL cleanup can remove entries older than the retention period.
+
+## Common failure categories
+- `tuf:*` - invalid/expired metadata or snapshot hash mismatch
+- `dsse:*` - signature invalid or trust root mismatch
+- `merkle-*` - payload entry set invalid or empty
+- `rotation:*` - root rotation policy failure (dual approval, no-op rotation, etc.)
+- `version-non-monotonic:*` - rollback prevention triggered (force activation requires a justification)

+# Smart-Diff Air-Gap Workflows
+
+**Sprint:** SPRINT_3500_0001_0001  
+**Task:** SDIFF-MASTER-0006 - Document air-gap workflows for smart-diff
+
+## Overview
+
+Smart-Diff can operate in fully air-gapped environments using offline bundles. This document describes the workflows for running smart-diff analysis without network connectivity.
+
+## Prerequisites
+
+1. **Offline Kit** - Downloaded and verified (`stellaops offline kit download`)
+2. **Feed Snapshots** - Pre-staged vulnerability feeds
+3. **SBOM Cache** - Pre-generated SBOMs for target artifacts
+
+## Workflow 1: Offline Smart-Diff Analysis
+
+### Step 1: Prepare Offline Bundle
+
+On a connected machine:
+
+```bash
+# Download offline kit with feeds
+stellaops offline kit download \

+```
+
+### Step 2: Transfer to Air-Gapped Environment
+
+Transfer the bundle using approved media:
+- USB drive (scanned and approved)
+- Optical media (DVD/Blu-ray)
+- Data diode
+
+### Step 3: Import Bundle
+
+On the air-gapped machine:
+
+```bash
+# Verify bundle signature
+stellaops offline kit verify \
+  --input stellaops-offline-2025-01-15.tar.gz \
+  --public-key /path/to/signing-key.pub
+
+# Extract and configure
+stellaops offline kit import \
+  --input stellaops-offline-2025-01-15.tar.gz \
+  --data-dir /opt/stellaops/data
+```
+
+### Step 4: Run Smart-Diff
+
+```bash
+# Set offline mode
+export STELLAOPS_OFFLINE=true
+export STELLAOPS_DATA_DIR=/opt/stellaops/data
+
+# Run smart-diff
+stellaops smart-diff \
+  --base sbom:app-v1.json \
+  --target sbom:app-v2.json \
+  --output smart-diff-report.json
+```
+
+## Workflow 2: Pre-Computed Smart-Diff Export
+
+For environments where even running analysis tools is restricted.
+
+### Step 1: Prepare Artifacts (Connected Machine)
+
+```bash
+# Generate SBOMs
+stellaops sbom generate --artifact app:v1 --output app-v1-sbom.json
+stellaops sbom generate --artifact app:v2 --output app-v2-sbom.json
+
+# Run smart-diff with full proof bundle
+stellaops smart-diff \
+  --base app-v1-sbom.json \
+  --target app-v2-sbom.json \
+  --output-dir ./smart-diff-export \
+  --include-proofs \
+  --include-evidence \
+  --format bundle
+```
+
+### Step 2: Verify Export Contents
+
+The export bundle contains:
+```
+smart-diff-export/
+├── manifest.json           # Signed manifest
+├── base-sbom.json          # Base SBOM (hash verified)
+├── target-sbom.json        # Target SBOM (hash verified)
+├── diff-results.json       # Smart-diff findings
+├── sarif-report.json       # SARIF formatted output
+├── proofs/
+│   ├── ledger.json         # Proof ledger
+│   └── nodes/              # Individual proof nodes
+├── evidence/
+│   ├── reachability.json   # Reachability evidence
+│   ├── vex-statements.json # VEX statements
+│   └── hardening.json      # Binary hardening data
+└── signature.dsse          # DSSE envelope
+```
+
+### Step 3: Import and Verify (Air-Gapped Machine)
+
+```bash
+# Verify bundle integrity
+stellaops verify-bundle \
+  --input smart-diff-export \
+  --public-key /path/to/trusted-key.pub
+
+# View results
+stellaops smart-diff show \
+  --bundle smart-diff-export \
+  --format table
+```
+
+## Workflow 3: Incremental Feed Updates
+
+### Step 1: Generate Delta Feed
+
+On connected machine:
+
+```bash
+# Generate delta since last sync
+stellaops offline feed delta \
+  --since 2025-01-10 \
+  --output feed-delta-2025-01-15.tar.gz \
+  --sign
+```
+
+### Step 2: Apply Delta (Air-Gapped)
+
+```bash
+# Import delta
+stellaops offline feed apply \
+  --input feed-delta-2025-01-15.tar.gz \
+  --verify
+
+# Trigger score replay for affected scans
+stellaops score replay-all \
+  --trigger feed-update \
+  --dry-run
+```
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `STELLAOPS_OFFLINE` | Enable offline mode | `false` |
+| `STELLAOPS_DATA_DIR` | Local data directory | `~/.stellaops` |
+| `STELLAOPS_FEED_DIR` | Feed snapshot directory | `$DATA_DIR/feeds` |
+| `STELLAOPS_SBOM_CACHE` | SBOM cache directory | `$DATA_DIR/sboms` |
+| `STELLAOPS_SKIP_NETWORK` | Block network requests | `false` |
+| `STELLAOPS_REQUIRE_SIGNATURES` | Require signed data | `true` |
+
+### Config File
+
+```yaml
+# ~/.stellaops/config.yaml
+offline:
+  enabled: true
+  data_dir: /opt/stellaops/data
+  require_signatures: true
+  
+feeds:
+  source: local
+  path: /opt/stellaops/data/feeds
+  
+sbom:
+  cache_dir: /opt/stellaops/data/sboms
+  
+network:
+  allow_list: []  # Empty = no network
+```
+
+## Verification
+
+### Verify Feed Freshness
+
+```bash
+# Check feed dates
+stellaops offline status
+
+# Output:
+# Feed Status (Offline Mode)
+# ─────────────────────────────
+# NVD:  2025-01-15 (2 days old)
+# OSV:  2025-01-15 (2 days old)
+# EPSS: 2025-01-14 (3 days old)
+# KEV:  2025-01-15 (2 days old)
+```
+
+### Verify Proof Integrity
+
+```bash
+# Verify smart-diff proofs
+stellaops smart-diff verify \
+  --input smart-diff-report.json \
+  --proof-bundle ./proofs
+
+# Output:
+# ✓ Manifest hash verified
+# ✓ All proof nodes valid
+# ✓ Root hash matches: sha256:abc123...
+```
+
+## Determinism Guarantees
+
+Offline smart-diff maintains determinism by:
+
+1. **Content-addressed feeds** - Same feed hash = same results
+2. **Frozen timestamps** - All timestamps use manifest creation time
+3. **No network randomness** - No external API calls
+4. **Stable sorting** - Deterministic output ordering
+
+### Reproducibility Test
+
+```bash
+# Run twice and compare
+stellaops smart-diff --base a.json --target b.json --output run1.json
+stellaops smart-diff --base a.json --target b.json --output run2.json
+
+# Compare hashes
+sha256sum run1.json run2.json
+# abc123...  run1.json
+# abc123...  run2.json  (identical)
+```
+
+## Troubleshooting
+
+### Error: Feed not found
+
+```
+Error: Feed 'nvd' not found in offline data directory
+```
+
+**Solution:** Ensure feed was included in offline kit:
+```bash
+stellaops offline kit status
+ls $STELLAOPS_FEED_DIR/nvd/
+```
+
+### Error: Network request blocked
+
+```
+Error: Network request blocked in offline mode: api.osv.dev
+```
+
+**Solution:** This is expected behavior. Ensure all required data is in offline bundle.
+
+### Error: Signature verification failed
+
+```
+Error: Bundle signature verification failed
+```
+
+**Solution:** Ensure correct public key is configured:
+```bash
+stellaops offline kit verify \
+  --input bundle.tar.gz \
+  --public-key /path/to/correct-key.pub
+```

+# Triage Air-Gap Workflows
+
+**Sprint:** SPRINT_3600_0001_0001  
+**Task:** TRI-MASTER-0006 - Document air-gap triage workflows
+
+## Overview
+
+This document describes how to perform vulnerability triage in fully air-gapped environments. The triage workflow supports offline evidence bundles, decision capture, and replay token generation.
+
+## Workflow 1: Offline Triage with Evidence Bundles
+
+### Step 1: Export Evidence Bundle (Connected Machine)
+
+```bash
+# Export triage bundle for specific findings
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --findings CVE-2024-1234,CVE-2024-5678 \
+  --include-evidence \
+  --include-graph \
+  --output triage-bundle.stella.bundle.tgz
+
+# Export entire scan for offline review
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --all-findings \
+  --output full-triage-bundle.stella.bundle.tgz
+```
+
+### Step 2: Bundle Contents
+
+The `.stella.bundle.tgz` archive contains:
+
+```
+triage-bundle.stella.bundle.tgz/
+├── manifest.json           # Signed bundle manifest
+├── findings/
+│   ├── index.json          # Finding list with IDs
+│   ├── CVE-2024-1234.json  # Finding details
+│   └── CVE-2024-5678.json
+├── evidence/
+│   ├── reachability/       # Reachability proofs
+│   ├── callstack/          # Call stack snippets
+│   ├── vex/                # VEX/CSAF statements
+│   └── provenance/         # Provenance data
+├── graph/
+│   ├── nodes.ndjson        # Dependency graph nodes
+│   └── edges.ndjson        # Graph edges
+├── feeds/
+│   └── snapshot.json       # Feed snapshot metadata
+└── signature.dsse          # DSSE envelope
+```
+
+### Step 3: Transfer to Air-Gapped Environment
+
+Transfer using approved methods:
+- USB media (security scanned)
+- Optical media
+- Data diode
+
+### Step 4: Import and Verify
+
+On the air-gapped machine:
+
+```bash
+# Verify bundle integrity
+stellaops triage verify-bundle \
+  --input triage-bundle.stella.bundle.tgz \
+  --public-key /path/to/signing-key.pub
+
+# Import for offline triage
+stellaops triage import \
+  --input triage-bundle.stella.bundle.tgz \
+  --workspace /opt/stellaops/triage
+```
+
+### Step 5: Perform Offline Triage
+
+```bash
+# List findings in bundle
+stellaops triage list \
+  --workspace /opt/stellaops/triage
+
+# View finding with evidence
+stellaops triage show CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --show-evidence
+
+# Make triage decision
+stellaops triage decide CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --status not_affected \
+  --justification "Code path is unreachable due to config gating" \
+  --reviewer "security-team"
+```
+
+### Step 6: Export Decisions
+
+```bash
+# Export decisions for sync back
+stellaops triage export-decisions \
+  --workspace /opt/stellaops/triage \
+  --output decisions-2025-01-15.json \
+  --sign
+```
+
+### Step 7: Sync Decisions (Connected Machine)
+
+```bash
+# Import and apply decisions
+stellaops triage import-decisions \
+  --input decisions-2025-01-15.json \
+  --verify \
+  --apply
+```
+
+## Workflow 2: Batch Offline Triage
+
+For high-volume environments.
+
+### Step 1: Export Batch Bundle
+
+```bash
+# Export all untriaged findings
+stellaops triage export-batch \
+  --query "status=untriaged AND priority>=0.7" \
+  --limit 100 \
+  --output batch-triage-2025-01-15.stella.bundle.tgz
+```
+
+### Step 2: Offline Batch Processing
+
+```bash
+# Interactive batch triage
+stellaops triage batch \
+  --workspace /opt/stellaops/triage \
+  --input batch-triage-2025-01-15.stella.bundle.tgz
+
+# Keyboard shortcuts enabled:
+# j/k - Next/Previous finding
+# a   - Accept (affected)
+# n   - Not affected
+# w   - Will not fix
+# f   - False positive
+# u   - Undo last decision
+# q   - Quit (saves progress)
+```
+
+### Step 3: Export and Sync
+
+```bash
+# Export batch decisions
+stellaops triage export-decisions \
+  --workspace /opt/stellaops/triage \
+  --format json \
+  --sign \
+  --output batch-decisions.json
+```
+
+## Workflow 3: Evidence-First Offline Review
+
+### Step 1: Pre-compute Evidence
+
+On connected machine:
+
+```bash
+# Generate evidence for all high-priority findings
+stellaops evidence generate \
+  --scan-id scan-12345678 \
+  --priority-min 0.7 \
+  --output-dir ./evidence-pack
+
+# Include:
+# - Reachability analysis
+# - Call stack traces
+# - VEX lookups
+# - Dependency graph snippets
+```
+
+### Step 2: Package with Findings
+
+```bash
+stellaops triage package \
+  --scan-id scan-12345678 \
+  --evidence-dir ./evidence-pack \
+  --output evidence-triage.stella.bundle.tgz
+```
+
+### Step 3: Offline Review with Evidence
+
+```bash
+# Evidence-first view
+stellaops triage show CVE-2024-1234 \
+  --workspace /opt/stellaops/triage \
+  --evidence-first
+
+# Output:
+# ═══════════════════════════════════════════
+# CVE-2024-1234 · lodash@4.17.20
+# ═══════════════════════════════════════════
+#
+# EVIDENCE SUMMARY
+# ────────────────
+# Reachability: EXECUTED (tier 2/3)
+#   └─ main.js:42 → utils.js:15 → lodash/merge
+#
+# Call Stack:
+#   1. main.js:42    handleRequest()
+#   2. utils.js:15   mergeConfig()
+#   3. lodash:merge  <vulnerable>
+#
+# VEX Status: No statement found
+# EPSS: 0.45 (Medium)
+# KEV: No
+#
+# ─────────────────────────────────────────────
+# Press [a]ffected, [n]ot affected, [s]kip...

+
+## Replay Tokens
+
+Each decision generates a replay token for audit trail:
+
+```bash
+# View replay token
+stellaops triage show-token rt_abc123...
+
+# Output:
+# Replay Token: rt_abc123...
+# ─────────────────────────────
+# Finding: CVE-2024-1234
+# Decision: not_affected
+# Evidence Hash: sha256:xyz789...
+# Feed Snapshot: sha256:abc123...
+# Decided: 2025-01-15T14:30:00Z
+# Reviewer: security-team
+```
+
+### Verify Token
+
+```bash
+stellaops triage verify-token rt_abc123... \
+  --public-key /path/to/key.pub
+
+# ✓ Token signature valid
+# ✓ Evidence hash matches
+# ✓ Feed snapshot verified
+```
+
+## Troubleshooting
+
+### Error: Bundle signature invalid
+
+```
+Error: Bundle signature verification failed
+```
+
+**Solution:** Ensure the correct public key is used:
+```bash
+stellaops triage verify-bundle \
+  --input bundle.tgz \
+  --public-key /path/to/correct-key.pub \
+  --verbose
+```
+
+### Error: Evidence not found
+
+```
+Error: Evidence for CVE-2024-1234 not included in bundle
+```
+
+**Solution:** Re-export with evidence:
+```bash
+stellaops triage export \
+  --scan-id scan-12345678 \
+  --findings CVE-2024-1234 \
+  --include-evidence \
+  --output bundle.tgz
+```
+
+### Error: Decision sync conflict
+
+```
+Error: Finding CVE-2024-1234 has newer decision on server
+```
+
+**Solution:** Review and resolve:
+```bash
+stellaops triage import-decisions \
+  --input decisions.json \
+  --conflict-mode review
+
+# Options: keep-local, keep-server, newest, review
+```

+# Orchestrator · First Signal API
+
+Provides a fast “first meaningful signal” for a run (TTFS), with caching and ETag-based conditional requests.
+
+## Endpoint
+
+`GET /api/v1/orchestrator/runs/{runId}/first-signal`
+
+### Required headers
+- `X-Tenant-Id`: tenant identifier (string)
+
+### Optional headers
+- `If-None-Match`: weak ETag from a previous 200 response (supports multiple values)
+
+## Responses
+
+### 200 OK
+Returns the first signal payload and a weak ETag.
+
+Response headers:
+- `ETag`: weak ETag (for `If-None-Match`)
+- `Cache-Control: private, max-age=60`
+- `Cache-Status: hit|miss`
+- `X-FirstSignal-Source: snapshot|cold_start` (best-effort diagnostics)
+
+Body (`application/json`):
+```json
+{
+  "runId": "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa",
+  "firstSignal": {
+    "type": "started",
+    "stage": "unknown",
+    "step": null,
+    "message": "Run started",
+    "at": "2025-12-15T12:00:10+00:00",
+    "artifact": { "kind": "run", "range": null }
+  },
+  "summaryEtag": "W/\"...\""
+}
+```
+
+### 204 No Content
+Run exists but no signal is available yet (e.g., run has no jobs).
+
+### 304 Not Modified
+Returned when `If-None-Match` matches the current ETag.
+
+### 404 Not Found
+Run does not exist for the resolved tenant.
+
+### 400 Bad Request
+Missing/invalid tenant header or invalid parameters.
+
+## ETag semantics
+- Weak ETags are computed from a deterministic, canonical hash of the stable signal content.
+- Per-request diagnostics (e.g., cache hit/miss) are intentionally excluded from the ETag material.
+
+## Streaming (SSE)
+The run stream emits `first_signal` events when the signal changes:
+
+`GET /api/v1/orchestrator/stream/runs/{runId}`
+
+Event type:
+- `first_signal`
+
+Payload shape:
+```json
+{
+  "runId": "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa",
+  "etag": "W/\"...\"",
+  "signal": { "version": "1.0", "signalId": "...", "jobId": "...", "timestamp": "...", "kind": 1, "phase": 6, "scope": { "type": "run", "id": "..." }, "summary": "...", "etaSeconds": null, "lastKnownOutcome": null, "nextActions": null, "diagnostics": { "cacheHit": false, "source": "cold_start", "correlationId": "" } }
+}
+```
+
+## Configuration
+
+`appsettings.json`:
+```json

+# Proof Chain API Reference
+
+> **Version**: 1.0.0  
+> **OpenAPI Spec**: [`proofs-openapi.yaml`](./proofs-openapi.yaml)
+
+The Proof Chain API provides endpoints for creating and verifying cryptographic proof bundles that link SBOM entries to vulnerability assessments through attestable DSSE envelopes.
+
+---
+
+## Overview
+
+The proof chain creates an auditable, cryptographically-verifiable trail from vulnerability evidence through policy reasoning to VEX verdicts. Each component is signed with DSSE envelopes and aggregated into a merkle-rooted proof spine.
+
+### Proof Chain Components
+
+| Component | Predicate Type | Purpose |
+|-----------|----------------|---------|
+| **Evidence** | `evidence.stella/v1` | Raw findings from scanners/feeds |
+| **Reasoning** | `reasoning.stella/v1` | Policy evaluation trace |
+| **VEX Verdict** | `cdx-vex.stella/v1` | Final VEX status determination |
+| **Proof Spine** | `proofspine.stella/v1` | Merkle aggregation of all components |
+| **Verdict Receipt** | `verdict.stella/v1` | Human-readable verification receipt |
+
+### Content-Addressed IDs
+
+All proof chain components use content-addressed identifiers:
+
+```
+Format: sha256:<64-hex-chars>
+Example: sha256:e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6...
+```
+
+IDs are computed by:
+1. Canonicalizing the JSON payload (RFC 8785/JCS)
+2. Computing SHA-256 hash
+3. Prefixing with `sha256:`
+
+---
+
+## Authentication
+
+All endpoints require authentication via:
+
+- **Bearer Token**: Authority-issued OpToken with appropriate scopes
+- **mTLS**: Mutual TLS with client certificate (service-to-service)
+
+Required scopes:
+- `proofs.read` - Read proof bundles and receipts
+- `proofs.write` - Create proof spines
+- `anchors.manage` - Manage trust anchors
+- `proofs.verify` - Perform verification
+
+---
+
+## Endpoints
+
+### Proofs

+
+---
+
+## Error Handling
+
+All errors follow RFC 7807 Problem Details format:
+
+```json
+{
+  "title": "Validation Error",
+  "detail": "Evidence ID sha256:abc... not found",
+  "status": 422,
+  "errors": {
+    "evidenceIds[0]": ["Evidence not found"]
+  }
+}
+```
+
+### Common Error Codes
+
+| Status | Meaning |
+|--------|---------|
+| 400 | Invalid request format or parameters |
+| 401 | Authentication required |
+| 403 | Insufficient permissions |
+| 404 | Resource not found |
+| 409 | Conflict (e.g., anchor already exists) |
+| 422 | Validation error |
+| 500 | Internal server error |
+
+---
+
+## Offline Verification
+
+For air-gapped environments, verification can be performed without Rekor:
+
+```json
+{
+  "proofBundleId": "sha256:1a2b3c4d...",
+  "checkRekor": false
+}
+```
+
+This skips Rekor inclusion proof verification but still performs:
+- DSSE signature verification
+- Content-addressed ID recomputation
+- Merkle path verification

+# Scanner WebService API — Score Proofs & Reachability Extensions
+
+**Version**: 2.0
+**Base URL**: `/api/v1/scanner`
+**Authentication**: Bearer token (OpTok with DPoP/mTLS)
+**Sprint**: SPRINT_3500_0002_0003, SPRINT_3500_0003_0003
+
+---
+
+## Overview
+
+This document specifies API extensions to `Scanner.WebService` for:
+1. Scan manifests and deterministic replay
+2. Proof bundles (score proofs + reachability evidence)
+3. Call-graph ingestion and reachability analysis
+4. Unknowns management
+
+**Design Principles**:
+- All endpoints return canonical JSON (deterministic serialization)
+- Idempotency via `Content-Digest` headers (SHA-256)
+- DSSE signatures returned for all proof artifacts
+- Offline-first (bundles downloadable for air-gap verification)
+
+---

+# Score Replay API Reference
+
+**Sprint:** SPRINT_3401_0002_0001  
+**Task:** SCORE-REPLAY-014 - Update scanner API docs with replay endpoint
+
+## Overview
+
+The Score Replay API enables deterministic re-scoring of scans using historical manifests. This is essential for auditing, compliance verification, and investigating how scores change with updated advisory feeds.
+
+## Base URL
+
+```
+/api/v1/score
+```
+
+## Authentication
+
+All endpoints require Bearer token authentication:
+
+```http
+Authorization: Bearer <token>
+```
+
+Required scope: `scanner:replay:read` for GET, `scanner:replay:write` for POST
+
+## Endpoints
+
+### Replay Score
+
+```http
+POST /api/v1/score/replay
+```
+
+Re-scores a scan using the original manifest with an optionally different feed snapshot.
+
+#### Request Body
+
+```json
+{
+  "scanId": "scan-12345678-abcd",
+  "feedSnapshotHash": "sha256:abc123...",
+  "policyVersion": "1.0.0",
+  "dryRun": false
+}
+```
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `scanId` | string | Yes | Original scan ID to replay |
+| `feedSnapshotHash` | string | No | Feed snapshot to use (defaults to current) |
+| `policyVersion` | string | No | Policy version (defaults to original) |
+| `dryRun` | boolean | No | If true, calculates but doesn't persist |

+- `signature.dsse` - DSSE envelope
+
+## Scheduled Replay
+
+Scans can be automatically replayed when feed snapshots change.
+
+### Configuration
+
+```yaml
+# config/scanner.yaml
+score_replay:
+  enabled: true
+  schedule: "0 4 * * *"  # Daily at 4 AM UTC
+  max_age_days: 30       # Only replay scans from last 30 days
+  notify_on_delta: true  # Send notification if scores change
+  delta_threshold: 0.5   # Only notify if delta > threshold
+```
+
+### Trigger Types
+
+| Type | Description |
+|------|-------------|
+| `manual` | User-initiated via API |
+| `feed_update` | Triggered by new feed snapshot |
+| `policy_change` | Triggered by policy version change |
+| `scheduled` | Triggered by scheduled job |
+
+## Determinism Guarantees
+
+Score replay guarantees deterministic results when:
+
+1. **Same manifest hash** - All inputs are identical
+2. **Same scanner version** - Scoring algorithm unchanged
+3. **Same policy version** - Policy rules unchanged
+
+### Manifest Contents
+
+The manifest captures:
+- SBOM content hash
+- Rules snapshot hash
+- Advisory feed snapshot hash
+- Policy configuration hash
+- Scanner version
+
+### Verification
+
+```bash
+# Verify replay determinism
+curl -H "Authorization: Bearer $TOKEN" \
+  "https://scanner.example.com/api/v1/scans/{scanId}/manifest" \
+  | jq '.manifestHash'
+
+# Compare with replay
+curl -H "Authorization: Bearer $TOKEN" \
+  "https://scanner.example.com/api/v1/score/replays/{replayId}" \
+  | jq '.replayedManifestHash'
+```
+
+## Error Responses
+
+| Status | Code | Description |
+|--------|------|-------------|
+| 400 | `INVALID_SCAN_ID` | Scan ID not found |
+| 400 | `INVALID_FEED_SNAPSHOT` | Feed snapshot not found |
+| 400 | `MANIFEST_NOT_FOUND` | Scan manifest missing |
+| 401 | `UNAUTHORIZED` | Invalid token |
+| 403 | `FORBIDDEN` | Insufficient permissions |
+| 409 | `REPLAY_IN_PROGRESS` | Replay already running for scan |
+| 429 | `RATE_LIMITED` | Too many requests |
+
+## Rate Limits
+
+- POST replay: 10 requests/minute
+- GET replays: 100 requests/minute
+- GET manifest: 100 requests/minute

+# Stella Ops Triage API Contract v1
+
+Base path: `/api/triage/v1`
+
+This contract is served by `scanner.webservice` (or a dedicated triage facade that reads scanner-owned tables).
+All risk/lattice outputs originate from `scanner.webservice`.
+
+Key requirements:
+- Deterministic outputs (policyId + policyVersion + inputsHash).
+- Proof-linking (chips reference evidenceIds).
+- `concelier` and `excititor` preserve prune source: API surfaces source chains via `sourceRefs`.
+
+## 0. Conventions
+
+### 0.1 Identifiers
+- `caseId` == `findingId` (UUID). A case is a finding scoped to an asset/environment.
+- Hashes are hex strings.
+
+### 0.2 Caching
+- GET endpoints SHOULD return `ETag`.
+- Clients SHOULD send `If-None-Match`.
+
+### 0.3 Errors
+Standard error envelope:
+
+```json
+{
+  "error": {
+    "code": "string",
+    "message": "string",
+    "details": { "any": "json" },
+    "traceId": "string"
+  }
+}
+```
+
+Common codes:
+
+* `not_found`
+* `validation_error`
+* `conflict`
+* `unauthorized`
+* `forbidden`
+* `rate_limited`
+
+## 1. Findings Table

+
+## Reason Codes
+
+| Code | Description |
+|------|-------------|
+| `missing_vex` | No VEX statement for vulnerability |
+| `ambiguous_indirect_call` | Indirect call target unresolved |
+| `incomplete_sbom` | SBOM missing component data |
+| `unknown_platform` | Platform not recognized |
+| `missing_advisory` | No advisory data for CVE |
+| `conflicting_evidence` | Multiple conflicting data sources |
+| `stale_data` | Data exceeds freshness threshold |
+
+## Score Calculation
+
+The unknown score is calculated as:
+
+```
+score = 0.60 × blast + 0.30 × scarcity + 0.30 × pressure + containment_deduction
+```
+
+Where:
+- `blast` = normalized blast radius (0-1)
+- `scarcity` = evidence scarcity factor (0-1)  
+- `pressure` = exploit pressure (EPSS + KEV factor)
+- `containment_deduction` = -0.10 for enforced seccomp, -0.10 for read-only FS
+
+### Blast Radius Normalization
+
+```
+dependents_normalized = min(dependents / 50, 1.0)
+net_factor = 0.5 if net_facing else 0.0
+priv_factor = 0.5 if privilege == "root" else 0.0
+blast = min((dependents_normalized + net_factor + priv_factor) / 2, 1.0)
+```
+
+### Exploit Pressure
+
+```
+epss_normalized = epss ?? 0.35  // Default if unknown
+kev_factor = 0.30 if kev else 0.0
+pressure = min(epss_normalized + kev_factor, 1.0)
+```

+# Fidelity Metrics Framework
+
+> Sprint: SPRINT_3403_0001_0001_fidelity_metrics
+
+This document describes the three-tier fidelity metrics framework for measuring deterministic reproducibility in StellaOps scanner outputs.
+
+## Overview
+
+Fidelity metrics quantify how consistently the scanner produces outputs across replay runs. The framework provides three tiers of measurement, each capturing different aspects of reproducibility:
+
+| Metric | Abbrev. | Description | Target |
+|--------|---------|-------------|--------|
+| Bitwise Fidelity | BF | Byte-for-byte identical outputs | ≥ 0.98 |
+| Semantic Fidelity | SF | Normalized object equivalence | ≥ 0.99 |
+| Policy Fidelity | PF | Policy decision consistency | ≈ 1.0 |
+
+## Metric Definitions
+
+### Bitwise Fidelity (BF)
+
+Measures the proportion of replay runs that produce byte-for-byte identical outputs.
+
+```
+BF = identical_outputs / total_replays
+```
+
+**What it captures:**
+- SHA-256 hash equivalence of all output artifacts
+- Timestamp consistency
+- JSON formatting consistency
+- Field ordering consistency
+
+**When BF < 1.0:**
+- Timestamps embedded in outputs
+- Non-deterministic field ordering
+- Floating-point rounding differences
+- Random identifiers (UUIDs)
+
+### Semantic Fidelity (SF)
+
+Measures the proportion of replay runs that produce semantically equivalent outputs, ignoring formatting differences.
+
+```
+SF = semantic_matches / total_replays
+```
+
+**What it compares:**
+- Package PURLs and versions
+- CVE identifiers
+- Severity levels (normalized to uppercase)
+- VEX verdicts
+- Reason codes
+
+**When SF < 1.0 but BF = SF:**
+- No actual content differences
+- Only formatting differences
+
+**When SF < 1.0:**
+- Different packages detected
+- Different CVEs matched
+- Different severity assignments
+
+### Policy Fidelity (PF)
+
+Measures the proportion of replay runs that produce matching policy decisions.
+
+```
+PF = policy_matches / total_replays
+```
+
+**What it compares:**
+- Final pass/fail decision
+- Reason codes (sorted for comparison)
+- Policy rule triggering
+
+**When PF < 1.0:**
+- Policy outcome differs between runs
+- Indicates a non-determinism bug that affects user-visible decisions
+
+## Prometheus Metrics
+
+The fidelity framework exports the following metrics:
+
+| Metric Name | Type | Labels | Description |
+|-------------|------|--------|-------------|
+| `fidelity_bitwise_ratio` | Gauge | tenant_id, surface_id | Bitwise fidelity ratio |
+| `fidelity_semantic_ratio` | Gauge | tenant_id, surface_id | Semantic fidelity ratio |
+| `fidelity_policy_ratio` | Gauge | tenant_id, surface_id | Policy fidelity ratio |
+| `fidelity_total_replays` | Gauge | tenant_id, surface_id | Number of replays |
+| `fidelity_slo_breach_total` | Counter | breach_type, tenant_id | SLO breach count |
+
+## SLO Thresholds
+
+Default SLO thresholds (configurable):
+
+| Metric | Warning | Critical |
+|--------|---------|----------|
+| Bitwise Fidelity | < 0.98 | < 0.90 |
+| Semantic Fidelity | < 0.99 | < 0.95 |
+| Policy Fidelity | < 1.0 | < 0.99 |
+
+## Integration with DeterminismReport
+
+Fidelity metrics are integrated into the `DeterminismReport` record:
+
+```csharp
+public sealed record DeterminismReport(
+    // ... existing fields ...
+    FidelityMetrics? Fidelity = null);
+
+public sealed record DeterminismImageReport(
+    // ... existing fields ...
+    FidelityMetrics? Fidelity = null);
+```
+
+## Usage Example
+
+```csharp
+// Create fidelity metrics service
+var service = new FidelityMetricsService(
+    new BitwiseFidelityCalculator(),
+    new SemanticFidelityCalculator(),
+    new PolicyFidelityCalculator());
+
+// Compute fidelity from baseline and replays
+var baseline = LoadScanResult("scan-baseline.json");
+var replays = LoadReplayScanResults();
+var fidelity = service.Compute(baseline, replays);
+
+// Check thresholds
+if (fidelity.BitwiseFidelity < 0.98)
+{
+    logger.LogWarning("BF below threshold: {BF}", fidelity.BitwiseFidelity);
+}
+
+// Include in determinism report
+var report = new DeterminismReport(
+    // ... other fields ...
+    Fidelity: fidelity);
+```
+
+## Mismatch Diagnostics
+
+When fidelity is below threshold, the framework provides diagnostic information:
+
+```csharp
+public sealed record FidelityMismatch
+{
+    public required int RunIndex { get; init; }
+    public required FidelityMismatchType Type { get; init; }
+    public required string Description { get; init; }
+    public IReadOnlyList<string>? AffectedArtifacts { get; init; }
+}
+
+public enum FidelityMismatchType
+{
+    BitwiseOnly,    // Hash differs but content equivalent
+    SemanticOnly,   // Content differs but policy matches
+    PolicyDrift     // Policy decision differs
+}
+```
+
+## Configuration
+
+Configure fidelity options via `FidelityThresholds`:
+
+```json
+{
+  "Fidelity": {
+    "BitwiseThreshold": 0.98,
+    "SemanticThreshold": 0.99,
+    "PolicyThreshold": 1.0,
+    "EnableDiagnostics": true,
+    "MaxMismatchesRecorded": 100
+  }
+}
+```

+# Ground-Truth Corpus Specification
+
+> **Version**: 1.0.0  
+> **Last Updated**: 2025-12-17  
+> **Source Advisory**: 16-Dec-2025 - Building a Deeper Moat Beyond Reachability
+
+This document specifies the ground-truth corpus for benchmarking StellaOps' binary-only reachability analysis and deterministic scoring.
+
+---
+
+## Overview
+
+A ground-truth corpus is a curated set of binaries with **known** reachable and unreachable vulnerable sinks. It enables:
+- Precision/recall measurement for reachability claims
+- Regression detection in CI
+- Deterministic replay validation
+
+---
+
+## Corpus Structure
+
+### Sample Requirements
+
+Each sample binary must include:
+- **Manifest file**: `sample.manifest.json` with ground-truth annotations
+- **Binary file**: The target executable (ELF/PE/Mach-O)
+- **Source (optional)**: Original source for reproducibility verification
+

+## Corpus Maintenance
+
+### Adding New Samples
+
+1. Create sample binary with known sink reachability
+2. Write `sample.manifest.json` with ground-truth annotations
+3. Place in `datasets/reachability/ground-truth/{category}/`
+4. Update corpus version in `datasets/reachability/corpus.json`
+5. Run baseline update: `stellaops bench baseline update`
+
+### Updating Baselines
+
+When scanner improvements are validated:
+```bash
+stellaops bench baseline update \
+  --results bench/results/latest.json \
+  --output bench/baselines/current.json
+```
+
+### Sample Categories
+
+- `basic/` — Simple direct call chains
+- `indirect/` — Function pointers, vtables, callbacks
+- `stripped/` — Symbol-stripped binaries
+- `obfuscated/` — Control-flow obfuscation, packing
+- `guarded/` — Config/auth/privilege guards
+- `multiarch/` — ARM64, x86, RISC-V variants

 ## TL;DR
 - StellaOps runs as a multi-service platform with deterministic SBOM generation, attestation (DSSE + Rekor), and tenant-aware controls, whereas Grype is a single Go CLI that leans on Syft to build SBOMs before vulnerability matching.[1](#sources)[g1](#grype-sources)
 - Grype covers a broad OS and language matrix via Syft catalogers and Anchore’s aggregated vulnerability database, but it lacks attestation, runtime usage context, and secret management features found in StellaOps’ Surface/Policy ecosystem.[1](#sources)[g2](#grype-sources)[g3](#grype-sources)

 ## TL;DR
 - StellaOps delivers a self-hosted, multi-service scanning plane with deterministic SBOMs, attestation (DSSE + Rekor), and tenant-aware Surface controls, while the Snyk CLI is a Node.js tool that authenticates against Snyk’s SaaS to analyse dependency graphs, containers, IaC, and code.[1](#sources)[s1](#snyk-sources)
 - Snyk’s plugin ecosystem covers many package managers (npm, yarn, pnpm, Maven, Gradle, NuGet, Go modules, Composer, etc.) and routes scans through Snyk’s cloud for policy, reporting, and fix advice; however it lacks offline operation, deterministic evidence, and attestation workflows that StellaOps provides out of the box.[1](#sources)[s1](#snyk-sources)[s2](#snyk-sources)

 ## TL;DR
 - StellaOps Scanner stays focused on deterministic, tenant-scoped SBOM production with signed evidence, policy hand-offs, and Surface primitives that keep offline deployments first-class.[1](#sources)
 - Trivy delivers broad, single-binary coverage (images, filesystems, repos, VMs, Kubernetes, SBOM input) with multiple scanners (vuln, misconfig, secret, license) and a rich plugin ecosystem, but it leaves provenance, signing, and multi-tenant controls to downstream tooling.[8](#sources)

+# Smart-Diff Weighted Impact Index (WII)
+
+**Source Advisory:** `docs/product-advisories/unprocessed/16-Dec-2025 - Smart‑Diff Meets Call‑Stack Reachability.md`  
+**Status:** Processed 2025-12-17
+
+## Overview
+
+The Weighted Impact Index (WII) is a composite score (0-100) that combines Smart-Diff semantic analysis with call-stack reachability to measure the runtime risk of code changes. It proves not just "what changed" but "how risky the change is in reachable code."
+
+## Core Concepts
+
+### Inputs
+
+1. **Smart-Diff Output** - Semantic differences between artifact states
+2. **Call Graph** - Symbol nodes with call edges
+3. **Entrypoints** - HTTP routes, jobs, message handlers
+4. **Runtime Heat** - pprof, APM, or eBPF execution frequency data
+5. **Advisory Data** - CVSS v4, EPSS v4 scores
+
+### WII Scoring Model
+
+The WII uses 8 weighted features per diff unit:
+
+| Feature | Weight | Description |
+|---------|--------|-------------|
+| `Δreach_len` | 0.25 | Change in shortest reachable path length |
+| `Δlib_depth` | 0.10 | Change in library call depth |
+| `exposure` | 0.15 | Public/external-facing API |
+| `privilege` | 0.15 | Path crosses privileged sinks |
+| `hot_path` | 0.15 | Frequently executed (runtime evidence) |
+| `cvss_v4` | 0.10 | Normalized CVSS v4 severity |
+| `epss_v4` | 0.10 | Exploit probability |
+| `guard_coverage` | -0.10 | Sanitizers/validations reduce score |
+
+### Determinism Bonus
+
+When `reachability == true` AND (`cvss_v4 > 0.7` OR `epss_v4 > 0.5`), add +5 bonus for "evidence-linked determinism."
+
+### Formula
+
+```
+WII = clamp(0, 1, Σ(w_i × feature_i_normalized)) × 100
+```
+
+## Data Structures
+
+### DiffUnit
+
+```json
+{
+  "unitId": "pkg:npm/lodash@4.17.21#function:merge",
+  "change": "modified",
+  "before": {"hash": "sha256:abc...", "attrs": {}},
+  "after": {"hash": "sha256:def...", "attrs": {}},
+  "features": {
+    "reachable": true,
+    "reachLen": 3,
+    "libDepth": 2,
+    "exposure": true,
+    "privilege": false,
+    "hotPath": true,
+    "cvssV4": 0.75,
+    "epssV4": 0.45,
+    "guardCoverage": false
+  },
+  "wii": 68
+}
+```
+
+### Artifact-Level WII
+
+Two metrics for artifact-level impact:
+- `max(WII_unit)` - Spike impact (single highest risk change)
+- `p95(WII_unit)` - Broad impact (distribution of risk)
+
+## DSSE Attestation
+
+The WII is emitted as a DSSE-signed attestation:
+
+```json
+{
+  "_type": "https://in-toto.io/Statement/v1",
+  "subject": [{"name": "ghcr.io/acme/app:1.9.3", "digest": {"sha256": "..."}}],
+  "predicateType": "https://stella-ops.org/attestations/smart-diff-wii@v1",
+  "predicate": {
+    "artifactBefore": {"digest": {"sha256": "..."}},
+    "artifactAfter": {"digest": {"sha256": "..."}},
+    "evidence": {
+      "sbomBefore": {"digest": {"sha256": "..."}},
+      "sbomAfter": {"digest": {"sha256": "..."}},
+      "callGraph": {"digest": {"sha256": "..."}},
+      "runtimeHeat": {"optional": true, "digest": {"sha256": "..."}}
+    },
+    "units": [...],
+    "aggregateWII": {
+      "max": 85,
+      "p95": 62,
+      "mean": 45
+    }
+  }
+}
+```
+
+## Pipeline Integration
+
+1. **Collect** - Build call graph, import SBOMs, CVE/EPSS data
+2. **Diff** - Run Smart-Diff to generate `DiffUnit[]`
+3. **Enrich** - Query reachability engine per unit
+4. **Score** - Compute per-unit and aggregate WII
+5. **Attest** - Emit DSSE statement with evidence URIs
+6. **Store** - Proof-Market Ledger (Rekor) + PostgreSQL
+
+## Use Cases
+
+### CI/CD Gates
+
+```yaml
+# .github/workflows/security.yml
+- name: Smart-Diff WII Check
+  run: |
+    stellaops smart-diff \
+      --base ${{ env.BASE_IMAGE }} \
+      --target ${{ env.TARGET_IMAGE }} \
+      --wii-threshold 70 \
+      --fail-on-threshold
+```
+
+### Risk Prioritization
+
+Sort changes by WII for review prioritization:
+
+```bash
+stellaops smart-diff show \
+  --sort wii \
+  --format table
+```
+
+### Attestation Verification
+
+```bash
+stellaops verify-attestation \

+# Tiered Precision Curves for Scanner Accuracy
+
+**Advisory:** 16-Dec-2025 - Measuring Progress with Tiered Precision Curves  
+**Status:** Processing  
+**Related Sprints:** SPRINT_3500_0003_0001 (Ground-Truth Corpus)
+
+## Executive Summary
+
+This advisory introduces a tiered approach to measuring scanner accuracy that prevents metric gaming. By tracking precision/recall separately for three evidence tiers (Imported, Executed, Tainted→Sink), we ensure improvements in one tier don't hide regressions in another.
+
+## Key Concepts
+
+### Evidence Tiers
+
+| Tier | Description | Risk Level | Typical Volume |
+|------|-------------|------------|----------------|
+| **Imported** | Vuln exists in dependency | Lowest | High |
+| **Executed** | Code/deps actually run | Medium | Medium |
+| **Tainted→Sink** | User data reaches sink | Highest | Low |
+
+### Tier Precedence
+
+Highest tier wins when a finding has multiple evidence types:
+1. `tainted_sink` (highest)
+2. `executed`
+3. `imported`
+
+## Implementation Components
+
+### 1. Evidence Schema (`eval` schema)
+
+```sql
+-- Ground truth samples
+eval.sample(sample_id, name, repo_path, commit_sha, language, scenario, entrypoints)
+
+-- Expected findings
+eval.expected_finding(expected_id, sample_id, vuln_key, tier, rule_key, sink_class)
+
+-- Evaluation runs
+eval.run(eval_run_id, scanner_version, rules_hash, concelier_snapshot_hash)
+
+-- Observed results
+eval.observed_finding(observed_id, eval_run_id, sample_id, vuln_key, tier, score, rule_key, evidence)
+
+-- Computed metrics
+eval.metrics(eval_run_id, tier, op_point, precision, recall, f1, pr_auc, latency_p50_ms)
+```
+
+### 2. Scanner Worker Changes
+
+Workers emit evidence primitives:
+- `DependencyEvidence { purl, version, lockfile_path }`
+- `ReachabilityEvidence { entrypoint, call_path[], confidence }`
+- `TaintEvidence { source, sink, sanitizers[], dataflow_path[], confidence }`
+
+### 3. Scanner WebService Changes
+
+WebService performs tiering:
+- Merge evidence for same `vuln_key`
+- Run reachability/taint algorithms
+- Assign `evidence_tier` deterministically
+- Persist normalized findings
+
+### 4. Evaluator CLI
+
+New tool `StellaOps.Scanner.Evaluation.Cli`:
+- `import-corpus` - Load samples and expected findings
+- `run` - Trigger scans using replay manifest
+- `compute` - Calculate per-tier PR curves
+- `report` - Generate markdown artifacts
+
+### 5. CI Gates
+
+Fail builds when:
+- PR-AUC(imported) drops > 2%
+- PR-AUC(executed/tainted_sink) drops > 1%
+- FP rate in `tainted_sink` > 5% at Recall ≥ 0.7
+
+## Operating Points
+
+| Tier | Target Recall | Purpose |
+|------|--------------|---------|
+| `imported` | ≥ 0.60 | Broad coverage |
+| `executed` | ≥ 0.70 | Material risk |
+| `tainted_sink` | ≥ 0.80 | Actionable findings |
+
+## Integration with Existing Systems
+
+### Concelier
+- Stores advisory data, does not tier
+- Tag advisories with sink classes when available
+
+### Excititor (VEX)
+- Include `tier` in VEX statements
+- Allow policy per-tier thresholds
+- Preserve pruning provenance
+
+### Notify
+- Gate alerts on tiered thresholds
+- Page only on `tainted_sink` at operating point
+
+### UI
+- Show tier badge on findings
+- Default sort: tainted_sink > executed > imported
+- Display evidence summary (entrypoint, path length, sink class)
+
+## Success Criteria
+
+1. Can demonstrate release where overall precision stayed flat but tainted→sink PR-AUC improved
+2. On-call noise reduced via tier-gated paging
+3. TTFS p95 for tainted→sink within budget

+- Tiered precision tracking (new)
+- Per-tier operating points (new)
+- CI gates based on tier-specific AUC (enhancement)

+stellaops scan image:tag --output-format sarif --tier tainted_sink
+
+# Executed and tainted_sink
+stellaops scan image:tag --output-format sarif --tier executed,tainted_sink
+```
+
+### By Priority
+
+```bash
+# Only high priority changes
+stellaops smart-diff --output-format sarif --min-priority 0.7
+```
+
+## Troubleshooting
+
+### SARIF Validation Errors
+
+If your CI platform rejects the SARIF output:
+
+1. Validate against schema:
+   ```bash
+   stellaops validate-sarif results.sarif
+   ```
+
+2. Check for required fields:
+   - `$schema` must be present
+   - `version` must be `"2.1.0"`
+   - Each result must have `ruleId` and `message`
+
+### Empty Results
+
+If SARIF contains no results:
+- Check scan completed successfully
+- Verify image has vulnerability data
+- Ensure feed snapshots are current

+# Smart-Diff Scoring Configuration Guide
+
+**Sprint:** SPRINT_3500_0004_0001  
+**Task:** SDIFF-BIN-031 - Documentation for scoring configuration
+
+## Overview
+
+Smart-Diff uses configurable scoring weights to prioritize material risk changes. This guide explains how to customize scoring for your organization's risk appetite.
+
+## Configuration Location
+
+Smart-Diff scoring can be configured via:
+1. **PolicyScoringConfig** - Integrated with policy engine
+2. **SmartDiffScoringConfig** - Standalone configuration
+3. **Environment variables** - Runtime overrides
+4. **API** - Dynamic configuration
+
+## Default Configuration
+
+```json
+{
+  "name": "default",
+  "version": "1.0",
+  "reachabilityFlipUpWeight": 1.0,
+  "reachabilityFlipDownWeight": 0.8,
+  "vexFlipToAffectedWeight": 0.9,
+  "vexFlipToNotAffectedWeight": 0.7,
+  "vexFlipToFixedWeight": 0.6,
+  "vexFlipToUnderInvestigationWeight": 0.3,
+  "rangeEntryWeight": 0.8,
+  "rangeExitWeight": 0.6,
+  "kevAddedWeight": 1.0,
+  "epssThreshold": 0.1,
+  "epssThresholdCrossWeight": 0.5,
+  "hardeningRegressionWeight": 0.7,
+  "hardeningImprovementWeight": 0.3,
+  "hardeningRegressionThreshold": 0.1
+}
+```
+
+## Weight Categories
+
+### Reachability Weights (R1)
+
+Controls scoring for reachability status changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `reachabilityFlipUpWeight` | 1.0 | Unreachable → Reachable (risk increase) |
+| `reachabilityFlipDownWeight` | 0.8 | Reachable → Unreachable (risk decrease) |
+| `useLatticeConfidence` | true | Factor in reachability confidence |
+
+**Example scenarios:**
+- Vulnerability becomes reachable after code refactoring → weight = 1.0
+- Dependency removed, vulnerability no longer reachable → weight = 0.8
+
+### VEX Status Weights (R2)
+
+Controls scoring for VEX statement changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `vexFlipToAffectedWeight` | 0.9 | Status changed to "affected" |
+| `vexFlipToNotAffectedWeight` | 0.7 | Status changed to "not_affected" |
+| `vexFlipToFixedWeight` | 0.6 | Status changed to "fixed" |
+| `vexFlipToUnderInvestigationWeight` | 0.3 | Status changed to "under_investigation" |
+
+**Rationale:**
+- "affected" is highest weight as it confirms exploitability
+- "fixed" is lower as it indicates remediation
+- "under_investigation" is lowest as status is uncertain
+
+### Version Range Weights (R3)
+
+Controls scoring for affected version range changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `rangeEntryWeight` | 0.8 | Version entered affected range |
+| `rangeExitWeight` | 0.6 | Version exited affected range |
+
+### Intelligence Signal Weights (R4)
+
+Controls scoring for external intelligence changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `kevAddedWeight` | 1.0 | Vulnerability added to CISA KEV |
+| `epssThreshold` | 0.1 | EPSS score threshold for significance |
+| `epssThresholdCrossWeight` | 0.5 | Weight when EPSS crosses threshold |
+
+### Binary Hardening Weights (R5)
+
+Controls scoring for binary hardening flag changes.
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `hardeningRegressionWeight` | 0.7 | Security flag disabled (e.g., NX removed) |
+| `hardeningImprovementWeight` | 0.3 | Security flag enabled (e.g., PIE added) |
+| `hardeningRegressionThreshold` | 0.1 | Minimum score drop to flag regression |
+
+## Presets
+
+### Default Preset
+
+Balanced configuration suitable for most organizations.
+
+```csharp
+SmartDiffScoringConfig.Default
+```
+
+### Strict Preset
+
+Higher weights for regressions, recommended for security-critical applications.
+
+```csharp
+SmartDiffScoringConfig.Strict
+```
+
+Configuration:
+```json
+{
+  "name": "strict",
+  "reachabilityFlipUpWeight": 1.2,
+  "vexFlipToAffectedWeight": 1.1,
+  "kevAddedWeight": 1.5,
+  "hardeningRegressionWeight": 1.0,
+  "hardeningRegressionThreshold": 0.05
+}
+```
+
+### Lenient Preset
+
+Lower weights for alerts, suitable for development/staging environments.
+
+```json
+{
+  "name": "lenient",
+  "reachabilityFlipUpWeight": 0.7,
+  "vexFlipToAffectedWeight": 0.6,
+  "kevAddedWeight": 0.8,
+  "hardeningRegressionWeight": 0.4,
+  "epssThreshold": 0.2
+}
+```
+
+## Policy Integration
+
+Smart-Diff scoring integrates with `PolicyScoringConfig`:
+
+```csharp
+var config = new PolicyScoringConfig(
+    Version: "1.0",
+    SeverityWeights: severityWeights,
+    QuietPenalty: 0.1,
+    WarnPenalty: 0.5,
+    IgnorePenalty: 0.0,
+    TrustOverrides: trustOverrides,
+    ReachabilityBuckets: reachabilityBuckets,
+    UnknownConfidence: unknownConfig,
+    SmartDiff: new SmartDiffPolicyScoringConfig(
+        ReachabilityFlipUpWeight: 1.0,
+        VexFlipToAffectedWeight: 0.9,
+        KevAddedWeight: 1.2
+    )
+);
+```
+
+## Environment Variable Overrides
+
+```bash
+# Override reachability weights
+export STELLAOPS_SMARTDIFF_REACHABILITY_FLIP_UP_WEIGHT=1.2
+export STELLAOPS_SMARTDIFF_REACHABILITY_FLIP_DOWN_WEIGHT=0.7
+
+# Override KEV weight
+export STELLAOPS_SMARTDIFF_KEV_ADDED_WEIGHT=1.5
+
+# Override hardening threshold
+export STELLAOPS_SMARTDIFF_HARDENING_REGRESSION_THRESHOLD=0.05
+```
+
+## API Configuration
+
+### Get Current Configuration
+
+```bash
+GET /api/v1/config/smart-diff/scoring
+
+Response:
+{
+  "name": "default",
+  "version": "1.0",
+  "weights": { ... }
+}
+```
+
+### Update Configuration
+
+```bash
+PUT /api/v1/config/smart-diff/scoring
+Content-Type: application/json
+
+{
+  "reachabilityFlipUpWeight": 1.2,
+  "kevAddedWeight": 1.5
+}
+```
+
+## Score Calculation Formula
+
+The final priority score is calculated as:
+
+```
+priority_score = base_severity × Σ(change_weight × rule_match)
+```
+
+Where:
+- `base_severity` is the CVSS/severity normalized to 0-1
+- `change_weight` is the configured weight for the change type
+- `rule_match` is 1 if the rule triggered, 0 otherwise
+
+### Example Calculation
+
+Given:
+- CVE-2024-1234 with CVSS 7.5 (base_severity = 0.75)
+- Became reachable (reachabilityFlipUpWeight = 1.0)
+- Added to KEV (kevAddedWeight = 1.0)
+
+```
+priority_score = 0.75 × (1.0 + 1.0) = 1.5 → capped at 1.0
+```
+
+## Tuning Recommendations
+
+### For CI/CD Pipelines
+
+```json
+{
+  "kevAddedWeight": 1.5,
+  "hardeningRegressionWeight": 1.2,
+  "epssThreshold": 0.05
+}
+```
+
+Focus on blocking builds for known exploited vulnerabilities and hardening regressions.
+
+### For Alert Fatigue Reduction
+
+```json
+{
+  "reachabilityFlipDownWeight": 0.3,
+  "vexFlipToNotAffectedWeight": 0.2,
+  "rangeExitWeight": 0.2
+}
+```
+
+Lower weights for positive changes to reduce noise.
+
+### For Compliance Focus
+
+```json
+{
+  "kevAddedWeight": 2.0,
+  "vexFlipToAffectedWeight": 1.2,
+  "hardeningRegressionThreshold": 0.02
+}
+```
+
+Higher weights for regulatory-relevant changes.
+
+## Monitoring and Metrics
+
+Track scoring effectiveness with:
+
+```sql
+-- Average priority score by rule type
+SELECT 
+  change_type,
+  AVG(priority_score) as avg_score,
+  COUNT(*) as count
+FROM smart_diff_changes
+WHERE created_at > now() - interval '30 days'
+GROUP BY change_type
+ORDER BY avg_score DESC;
+```

+
+## Overview
+
+The Ground-Truth Corpus is a collection of validated test samples used to measure scanner accuracy. Each sample has known reachability status and expected findings, enabling deterministic quality metrics.
+
+## Corpus Structure

+
+### expected.json

+{
+  "findings": [
+    {
+      "vuln_key": "CVE-2024-1234:pkg:pypi/sqlalchemy@1.4.0",
+      "tier": "tainted_sink",
+      "rule_key": "py.sql.injection.param_concat",
+      "sink_class": "sql",
+      "location_hint": "app.py:42"
+    }
+  ]
+}
+```
+
+## Contributing a Sample
+
+### Step 1: Choose a Scenario
+
+Select a scenario that is not well-covered in the corpus:
+
+| Scenario | Description | Example |
+|----------|-------------|---------|
+| `webapi` | Web application endpoint | Flask, FastAPI, Express |
+| `cli` | Command-line tool | argparse, click, commander |
+| `job` | Background/scheduled job | Celery, cron script |
+| `lib` | Library code | Reusable package |
+
+### Step 2: Create Sample Directory
+
+```bash
+cd datasets/reachability/samples
+mkdir gt-NNNN
+cd gt-NNNN
+```
+
+Use the next available sample ID (check `corpus.json` for the highest).
+
+### Step 3: Create Minimal Reproducible Case
+
+**Requirements:**
+- Smallest possible code to demonstrate the vulnerability
+- Real or realistic vulnerability (use CVE when possible)
+- Clear entrypoint definition
+- Deterministic behavior (no network, no randomness)
+
+**Example Python Sample:**
+
+```python
+# app.py - gt-0001
+from flask import Flask, request
+import sqlite3
+
+app = Flask(__name__)
+
+@app.route("/user")
+def get_user():
+    user_id = request.args.get("id")  # Taint source
+    conn = sqlite3.connect(":memory:")
+    # SQL injection: user_id flows to query without sanitization
+    result = conn.execute(f"SELECT * FROM users WHERE id = {user_id}")  # Taint sink
+    return str(result.fetchall())
+
+if __name__ == "__main__":
+    app.run()
+```
+
+### Step 4: Define Expected Findings
+
+Create `expected.json` with all expected findings:
+
+```json
+{
+  "findings": [
+    {
+      "vuln_key": "CWE-89:pkg:pypi/flask@2.0.0",
+      "tier": "tainted_sink",
+      "rule_key": "py.sql.injection",
+      "sink_class": "sql",
+      "location_hint": "app.py:13",
+      "notes": "User input from request.args flows to sqlite3.execute"
+    }
+  ]
+}
+```
+
+### Step 5: Create SBOM
+
+Generate or create an SBOM for the sample:
+
+```json
+{
+  "bomFormat": "CycloneDX",
+  "specVersion": "1.6",
+  "version": 1,
+  "components": [
+    {
+      "type": "library",
+      "name": "flask",
+      "version": "2.0.0",
+      "purl": "pkg:pypi/flask@2.0.0"
+    },
+    {
+      "type": "library",
+      "name": "sqlite3",
+      "version": "3.39.0",
+      "purl": "pkg:pypi/sqlite3@3.39.0"
+    }
+  ]
+}
+```
+
+### Step 6: Update Corpus Index
+
+Add entry to `corpus.json`:
+
+```json
+{
+  "id": "gt-0001",
+  "path": "samples/gt-0001",
+  "language": "python",
+  "tier": "tainted_sink",
+  "scenario": "webapi",
+  "expected_count": 1
+}
+```
+
+### Step 7: Validate Locally
+
+```bash
+# Run corpus validation
+dotnet test tests/reachability/StellaOps.Reachability.FixtureTests \
+  --filter "FullyQualifiedName~CorpusFixtureTests"
+
+# Run benchmark
+stellaops bench corpus run --sample gt-0001 --verbose
+```
+
+## Tier Guidelines
+
+### Imported Tier Samples
+
+For `imported` tier samples:
+- Vulnerability in a dependency
+- No execution path to vulnerable code
+- Package is in lockfile but not called
+
+**Example:** Unused dependency with known CVE.
+
+### Executed Tier Samples
+
+For `executed` tier samples:
+- Vulnerable code is called from entrypoint
+- No user-controlled data reaches the vulnerability
+- Static or coverage analysis proves execution
+
+**Example:** Hardcoded SQL query (no injection).
+
+### Tainted→Sink Tier Samples
+
+For `tainted_sink` tier samples:
+- User-controlled input reaches vulnerable code
+- Clear source → sink data flow
+- Include sink class taxonomy
+
+**Example:** User input to SQL query, command execution, etc.
+
+## Sink Classes
+
+When contributing `tainted_sink` samples, specify the sink class:
+
+| Sink Class | Description | Examples |
+|------------|-------------|----------|
+| `sql` | SQL injection | sqlite3.execute, cursor.execute |
+| `command` | Command injection | os.system, subprocess.run |
+| `ssrf` | Server-side request forgery | requests.get, urllib.urlopen |
+| `path` | Path traversal | open(), os.path.join |
+| `deser` | Deserialization | pickle.loads, yaml.load |
+| `eval` | Code evaluation | eval(), exec() |
+| `xxe` | XML external entity | lxml.parse, ET.parse |
+| `xss` | Cross-site scripting | innerHTML, document.write |
+
+## Quality Criteria
+
+Samples must meet these criteria:
+
+- [ ] **Deterministic**: Same input → same output
+- [ ] **Minimal**: Smallest code to demonstrate
+- [ ] **Documented**: Clear description and notes
+- [ ] **Validated**: Passes local tests
+- [ ] **Realistic**: Based on real vulnerability patterns
+- [ ] **Self-contained**: No external network calls
+
+## Negative Samples
+
+Include "negative" samples where scanner should NOT find vulnerabilities:
+
+```json
+{
+  "id": "gt-0050",
+  "name": "Python SQL - Properly Sanitized",
+  "tier": "imported",
+  "expected_count": 0,
+  "notes": "Uses parameterized queries, no injection possible"
+}
+```
+
+## Review Process
+
+1. Create PR with new sample(s)
+2. CI runs validation tests
+3. Security team reviews expected findings
+4. QA team verifies determinism
+5. Merge and update baseline
+
+## Updating Baselines
+
+After adding samples, update baseline metrics:
+
+```bash
+# Generate new baseline
+stellaops bench corpus run --all --output baselines/v1.1.0.json
+
+# Compare to previous
+stellaops bench corpus compare baselines/v1.0.0.json baselines/v1.1.0.json
+```
+
+## FAQ
+
+### How many samples should I contribute?
+
+Start with 2-3 high-quality samples covering different aspects of the same vulnerability class.
+
+### Can I use synthetic vulnerabilities?
+
+Yes, but prefer real CVE patterns when possible. Synthetic samples should document the vulnerability pattern clearly.
+
+### What if my sample has multiple findings?
+
+Include all expected findings in `expected.json`. Multi-finding samples are valuable for testing.
+
+### How do I test tier classification?
+
+Run with verbose output:
+```bash
+stellaops bench corpus run --sample gt-NNNN --verbose --show-evidence
+```

+### 5.3.1 Generated Columns for JSONB Hot Keys
+
+**RULE:** Frequently-queried JSONB fields (>10% of queries) SHOULD be extracted as generated columns.
+
+**When to use generated columns:**
+- Field is used in WHERE clauses frequently
+- Field is used in JOIN conditions
+- Field is used in GROUP BY or ORDER BY
+- Query planner needs cardinality statistics
+
+```sql
+-- ✓ CORRECT: Generated column for hot JSONB field
+ALTER TABLE scheduler.runs
+ADD COLUMN finding_count INT GENERATED ALWAYS AS ((stats->>'findingCount')::int) STORED;
+
+CREATE INDEX idx_runs_finding_count ON scheduler.runs(tenant_id, finding_count);
+```
+
+**RULE:** Generated column names MUST follow snake_case convention matching the JSON path.
+
+```sql
+-- ✓ CORRECT naming
+doc->>'bomFormat'      → bom_format
+stats->>'findingCount' → finding_count
+raw->>'schemaVersion'  → schema_version
+
+-- ✗ INCORRECT naming
+doc->>'bomFormat' → bomFormat, format, bf
+```
+
+**RULE:** Generated columns MUST be added with concurrent index creation in production.
+
+```sql
+-- ✓ CORRECT: Non-blocking migration
+ALTER TABLE scheduler.runs ADD COLUMN finding_count INT GENERATED ALWAYS AS (...) STORED;
+CREATE INDEX CONCURRENTLY idx_runs_finding_count ON scheduler.runs(finding_count);

+### 6.4 Generated Columns for JSONB Hot Keys
+
+For frequently-queried JSONB fields, use PostgreSQL generated columns to enable efficient B-tree indexing and query planning statistics.
+
+**Problem with expression indexes:**
+```sql
+-- Expression indexes don't collect statistics
+CREATE INDEX idx_format ON sbom_docs ((doc->>'bomFormat'));
+-- Query planner can't estimate cardinality, may choose suboptimal plans
+```
+
+**Solution: Generated columns (PostgreSQL 12+):**
+```sql
+-- Add generated column that extracts JSONB field
+ALTER TABLE scanner.sbom_documents
+ADD COLUMN bom_format TEXT GENERATED ALWAYS AS ((doc->>'bomFormat')) STORED;
+
+-- Standard B-tree index with full statistics
+CREATE INDEX idx_sbom_bom_format ON scanner.sbom_documents(bom_format);
+```
+
+**Benefits:**
+- **B-tree indexable**: Standard index on generated column
+- **Statistics**: `ANALYZE` collects cardinality, MCV, histogram
+- **Index-only scans**: Visible to covering indexes
+- **Zero application changes**: Transparent to ORM/queries
+
+**When to use generated columns:**
+- Field queried in >10% of queries against the table
+- Cardinality >100 distinct values (worth collecting stats)
+- Field used in JOIN conditions or GROUP BY
+- Index-only scans are beneficial
+
+**Naming convention:**

+-- Purpose:
+--   EPSS (Exploit Prediction Scoring System) v4 daily ingestion and storage.
+--   Provides time-series EPSS scores (0.0-1.0 probability) and percentiles

+# Scan Metrics Schema
+
+Sprint: `SPRINT_3406_0001_0001_metrics_tables`  
+Task: `METRICS-3406-013`  
+Working Directory: `src/Scanner/__Libraries/StellaOps.Scanner.Storage/Postgres/Migrations/`
+
+## Overview
+
+The scan metrics schema provides relational PostgreSQL tables for tracking Time-to-Evidence (TTE) and scan performance metrics. This is a hybrid approach where metrics are stored in PostgreSQL while replay manifests remain in the document store.
+
+## Tables
+
+### `scanner.scan_metrics`
+
+Primary table for per-scan metrics.
+
+| Column | Type | Description |
+|--------|------|-------------|
+| `metrics_id` | UUID | Primary key |
+| `scan_id` | UUID | Unique scan identifier |
+| `tenant_id` | UUID | Tenant identifier |
+| `surface_id` | UUID | Optional attack surface identifier |

+| `t_sign_ms` | INT | Sign phase duration |
+| `t_publish_ms` | INT | Publish phase duration |
+| `package_count` | INT | Number of packages analyzed |
+| `finding_count` | INT | Number of findings |
+| `vex_decision_count` | INT | Number of VEX decisions |
+| `scanner_version` | TEXT | Scanner version |
+| `scanner_image_digest` | TEXT | Scanner container digest |
+| `is_replay` | BOOLEAN | Replay mode flag |
+| `created_at` | TIMESTAMPTZ | Record creation time |
+
+### `scanner.execution_phases`
+
+Detailed phase execution tracking.
+
+| Column | Type | Description |
+|--------|------|-------------|
+| `id` | BIGSERIAL | Primary key |
+| `metrics_id` | UUID | Foreign key to `scan_metrics` |
+| `phase_name` | TEXT | Phase: `ingest`, `analyze`, `reachability`, `vex`, `sign`, `publish`, `other` |
+| `phase_order` | INT | Execution order |
+| `started_at` | TIMESTAMPTZ | Phase start time |
+| `finished_at` | TIMESTAMPTZ | Phase completion time |
+| `duration_ms` | INT | Duration in milliseconds (generated) |
+| `success` | BOOLEAN | Phase success status |
+| `error_code` | TEXT | Error code if failed |
+| `error_message` | TEXT | Error message if failed |
+| `phase_metrics` | JSONB | Phase-specific metrics |
+
+## Views
+
+### `scanner.scan_tte`
+
+Time-to-Evidence view with phase breakdowns.
+
+```sql
+SELECT
+    metrics_id,
+    scan_id,
+    tte_ms,
+    tte_seconds,
+    ingest_percent,
+    analyze_percent,
+    reachability_percent,
+    vex_percent,

+### `scanner.tte_stats`
+
+Hourly TTE statistics with SLO compliance.
+
+```sql
+SELECT
+    hour_bucket,
+    scan_count,
+    tte_avg_ms,
+    tte_p50_ms,
+    tte_p95_ms,
+    slo_p50_compliance_percent,
+    slo_p95_compliance_percent
+FROM scanner.tte_stats
+WHERE tenant_id = :tenant_id;
+```
+
+## Functions
+
+### `scanner.tte_percentile`
+
+Calculate TTE percentile for a tenant.
+
+```sql
+SELECT scanner.tte_percentile(
+    p_tenant_id := :tenant_id,
+    p_percentile := 0.95,
+    p_since := NOW() - INTERVAL '7 days'
+);
+```
+
+## Indexes
+
+| Index | Columns | Purpose |

+
+## SLO Thresholds
+
+Per the advisory section 13.1:
+
+| Metric | Target |
+|--------|--------|
+| TTE P50 | < 120 seconds |
+| TTE P95 | < 300 seconds |
+
+## Usage Examples
+
+### Get TTE for recent scans
+
+```sql
+SELECT scan_id, tte_ms, tte_seconds
+FROM scanner.scan_tte
+WHERE tenant_id = :tenant_id
+  AND NOT is_replay
+ORDER BY started_at DESC
+LIMIT 100;
+```
+
+### Check SLO compliance
+
+```sql
+SELECT
+    hour_bucket,
+    slo_p50_compliance_percent,
+    slo_p95_compliance_percent
+FROM scanner.tte_stats
+WHERE tenant_id = :tenant_id
+  AND hour_bucket >= NOW() - INTERVAL '24 hours';
+```
+
+### Phase breakdown analysis
+
+```sql
+SELECT
+    phase_name,
+    AVG(duration_ms) as avg_ms,
+    PERCENTILE_CONT(0.95) WITHIN GROUP (ORDER BY duration_ms) as p95_ms
+FROM scanner.execution_phases ep
+JOIN scanner.scan_metrics sm ON ep.metrics_id = sm.metrics_id
+WHERE sm.tenant_id = :tenant_id
+  AND sm.started_at >= NOW() - INTERVAL '7 days'
+GROUP BY phase_name
+ORDER BY phase_order;
+```
+
+## Migration
+
+Migration file: `src/Scanner/__Libraries/StellaOps.Scanner.Storage/Postgres/Migrations/004_scan_metrics.sql`
+
+Apply with:
+```bash
+psql -d stellaops -f 004_scan_metrics.sql

+3. Call-graph nodes and edges (reachability analysis)
+4. Entrypoints (framework-specific entry discovery)
+5. Runtime samples (profiling data for reachability validation)
+
+**Design Principles**:
+- All tables use `scan_id` as primary partition key for scan isolation
+- Deterministic data only (no timestamps in core algorithms)
+- Content-addressed references (hashes, not paths)
+- Forward-only schema evolution

+
+---
+
+## Performance Considerations
+
+### Query Patterns
+
+**High-frequency queries**:
+
+1. **Scan manifest lookup by artifact**:
+   ```sql
+   SELECT * FROM scanner.scan_manifest
+   WHERE artifact_digest = $1
+   ORDER BY created_at_utc DESC LIMIT 1;
+   ```
+   - Index: `idx_scan_manifest_artifact`
+
+2. **Reachability BFS (forward)**:
+   ```sql
+   SELECT to_node_id FROM scanner.cg_edge
+   WHERE scan_id = $1 AND from_node_id = ANY($2) AND kind = 1;
+   ```
+   - Index: `idx_cg_edge_from`
+
+3. **Reachability BFS (backward)**:
+   ```sql
+   SELECT from_node_id FROM scanner.cg_edge
+   WHERE scan_id = $1 AND to_node_id = $2 AND kind = 1;
+   ```
+   - Index: `idx_cg_edge_to`
+
+4. **Find runtime samples containing node**:
+   ```sql
+   SELECT * FROM scanner.runtime_sample
+   WHERE scan_id = $1 AND $2 = ANY(frames);
+   ```
+   - Index: `idx_runtime_sample_frames` (GIN)
+
+### Index Maintenance
+
+**Reindex schedule**:
+- `cg_edge` indexes: Weekly (high churn)
+- `runtime_sample` GIN index: Monthly (after partition drops)
+
+**Vacuum**:
+- Autovacuum enabled for all tables
+- Manual VACUUM ANALYZE after bulk inserts (>1M rows)
+
+### Partition Management
+
+**Automated partition creation** (cron job):
+
+```sql
+-- Create next month's partition 7 days in advance
+CREATE TABLE IF NOT EXISTS scanner.runtime_sample_2025_02 PARTITION OF scanner.runtime_sample
+    FOR VALUES FROM ('2025-02-01') TO ('2025-03-01');
+```
+
+**Automated partition dropping** (90-day retention):
+
+```sql
+DROP TABLE IF EXISTS scanner.runtime_sample_2024_10; -- Older than 90 days
+```
+
+---
+
+## Compliance & Auditing
+
+### DSSE Signatures
+
+All proof bundles and manifests include DSSE signatures:
+- `manifest_dsse_json` in `scan_manifest`
+- `proof_root_dsse_json` in `proof_bundle`
+
+**Verification**:
+- Signatures verified on read using `IContentSigner.Verify`
+- Invalid signatures → reject proof bundle
+
+### Immutability
+
+**Immutable tables**:
+- `scan_manifest` — No updates allowed after insert
+- `proof_bundle` — No updates allowed after insert
+
+**Enforcement**: Application-level (no UPDATE grants in production)
+
+### Retention Policies
+
+| Table | Retention | Enforcement |
+|-------|-----------|-------------|
+| `scan_manifest` | 180 days | DELETE WHERE created_at_utc < NOW() - INTERVAL '180 days' |
+| `proof_bundle` | 365 days | DELETE WHERE created_at_utc < NOW() - INTERVAL '365 days' |
+| `cg_node` | 90 days | CASCADE delete on scan_manifest |
+| `cg_edge` | 90 days | CASCADE delete on scan_manifest |
+| `runtime_sample` | 90 days | DROP PARTITION (monthly) |
+
+---
+
+## Monitoring
+
+### Key Metrics
+
+1. **Table sizes**:
+   ```sql
+   SELECT schemaname, tablename, pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename))
+   FROM pg_tables WHERE schemaname = 'scanner';
+   ```
+
+2. **Index usage**:
+   ```sql
+   SELECT indexrelname, idx_scan, idx_tup_read, idx_tup_fetch
+   FROM pg_stat_user_indexes
+   WHERE schemaname = 'scanner'
+   ORDER BY idx_scan DESC;
+   ```
+
+3. **Partition sizes**:
+   ```sql
+   SELECT tablename, pg_size_pretty(pg_total_relation_size('scanner.'||tablename))
+   FROM pg_tables
+   WHERE schemaname = 'scanner' AND tablename LIKE 'runtime_sample_%'
+   ORDER BY tablename DESC;
+   ```
+
+### Alerts
+
+- **Table growth**: Alert if `cg_edge` >10GB per scan
+- **Index bloat**: Alert if index size >2x expected
+- **Partition creation**: Alert if next month's partition not created 7 days in advance
+- **Vacuum lag**: Alert if last autovacuum >7 days
