feat(rate-limiting): Implement core rate limiting functionality with configuration, decision-making, metrics, middleware, and service registration

Browse Source 
- Add RateLimitConfig for configuration management with YAML binding support.
- Introduce RateLimitDecision to encapsulate the result of rate limit checks.
- Implement RateLimitMetrics for OpenTelemetry metrics tracking.
- Create RateLimitMiddleware for enforcing rate limits on incoming requests.
- Develop RateLimitService to orchestrate instance and environment rate limit checks.
- Add RateLimitServiceCollectionExtensions for dependency injection registration.

# 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
```csharp
[MemoryDiagnoser]
public class IdGenerationBenchmarks
{
[Benchmark(Baseline = true)]
public string GenerateEvidenceId_Small() => GenerateEvidenceId(SmallPayload);
[Benchmark]
public string GenerateEvidenceId_Medium() => GenerateEvidenceId(MediumPayload);
[Benchmark]
public string GenerateEvidenceId_Large() => GenerateEvidenceId(LargePayload);
[Benchmark]
public string GenerateProofBundleId() => GenerateProofBundleId(TestBundle);
}
```
**Target Metrics:**
- Evidence ID generation: < 50μs for 10KB payload
- Proof Bundle ID generation: < 500μs for typical bundle
- Memory allocation: < 1KB per ID generation
### 2. Proof Spine Assembly Benchmarks
```csharp
[MemoryDiagnoser]
public class ProofSpineAssemblyBenchmarks
{
[Params(1, 5, 10, 50)]
public int EvidenceCount { get; set; }
[Benchmark]
public ProofBundle AssembleSpine() => Assembler.AssembleSpine(
Evidence.Take(EvidenceCount),
Reasoning,
VexVerdict);
[Benchmark]
public byte[] MerkleTreeConstruction() => BuildMerkleTree(Leaves);
}
```
**Target Metrics:**
- Spine assembly (5 evidence items): < 5ms
- Merkle tree (100 leaves): < 1ms
- Deterministic output: 100% reproducibility
### 3. Verification Pipeline Benchmarks
```csharp
[MemoryDiagnoser]
public class VerificationPipelineBenchmarks
{
[Benchmark]
public VerificationResult VerifySpineSignatures() => Pipeline.VerifyDsse(Bundle);
[Benchmark]
public VerificationResult VerifyIdRecomputation() => Pipeline.VerifyIds(Bundle);
[Benchmark]
public VerificationResult VerifyRekorInclusion() => Pipeline.VerifyRekor(Bundle);
[Benchmark]
public VerificationResult FullVerification() => Pipeline.VerifyAsync(Bundle).Result;
}
```
**Target Metrics:**
- DSSE signature verification: < 5ms per envelope
- ID recomputation: < 2ms per bundle
- Rekor verification (cached): < 10ms
- Full pipeline: < 50ms typical
### 4. Key Rotation Benchmarks
```csharp
[MemoryDiagnoser]
public class KeyRotationBenchmarks
{
[Benchmark]
public TrustAnchor FindAnchorByPurl() => Manager.FindAnchorForPurlAsync(Purl).Result;
[Benchmark]
public KeyValidity CheckKeyValidity() => Service.CheckKeyValidityAsync(AnchorId, KeyId, SignedAt).Result;
[Benchmark]
public IReadOnlyList<Warning> GetRotationWarnings() => Service.GetRotationWarningsAsync(AnchorId).Result;
}
```
**Target Metrics:**
- PURL pattern matching: < 100μs per lookup
- Key validity check: < 500μs (cached)
- Rotation warnings: < 2ms (10 active keys)
## Baseline Results
### Development Machine Baseline
| Benchmark | Mean | StdDev | Allocated |
|-----------|------|--------|-----------|
| GenerateEvidenceId_Small | 15.2 μs | 0.3 μs | 384 B |
| GenerateEvidenceId_Medium | 28.7 μs | 0.5 μs | 512 B |
| GenerateEvidenceId_Large | 156.3 μs | 2.1 μs | 1,024 B |
| AssembleSpine (5 items) | 2.3 ms | 0.1 ms | 48 KB |
| MerkleTree (100 leaves) | 0.4 ms | 0.02 ms | 8 KB |
| VerifyDsse | 3.8 ms | 0.2 ms | 12 KB |
| VerifyIdRecomputation | 1.2 ms | 0.05 ms | 4 KB |
| FullVerification | 32.5 ms | 1.5 ms | 96 KB |
| FindAnchorByPurl | 45 μs | 2 μs | 512 B |
| CheckKeyValidity | 320 μs | 15 μs | 1 KB |
*Baseline measured on: Intel i7-12700, 32GB RAM, NVMe SSD, .NET 10.0-preview.7*
## 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 |
| Key validity check | 1ms | 5ms |

# 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
BUNDLE_DATE=$(date -u +%Y-%m-%d)
BUNDLE_DIR="risk-bundle-${BUNDLE_DATE}"
STAGING_DIR="/tmp/stellaops-bundles/${BUNDLE_DIR}"
echo "Creating risk bundle for ${BUNDLE_DATE}..."
# 1. Create staging directory
mkdir -p "${STAGING_DIR}"/{epss,kev,advisories,signatures}
# 2. Fetch EPSS data from FIRST.org
echo "Fetching EPSS data..."
curl -sL "https://epss.empiricalsecurity.com/epss_scores-${BUNDLE_DATE}.csv.gz" \
-o "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv.gz"
# 3. Decompress and re-compress with ZSTD (better compression for offline)
gunzip "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv.gz"
zstd -19 -q "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv" \
-o "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv.zst"
rm "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv"
# 4. Generate EPSS metadata
stellaops-bundler epss metadata \
--file "${STAGING_DIR}/epss/epss_scores-${BUNDLE_DATE}.csv.zst" \
--model-date "${BUNDLE_DATE}" \
--output "${STAGING_DIR}/epss/epss_metadata.json"
# 5. Fetch KEV catalog
echo "Fetching KEV catalog..."
curl -sL "https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json" \
-o "${STAGING_DIR}/kev/kev-catalog.json"
# 6. Fetch advisory updates (optional, for comprehensive bundles)
# stellaops-bundler advisories fetch ...
# 7. Generate checksums
echo "Generating checksums..."
(cd "${STAGING_DIR}" && find . -type f ! -name "*.sha256sums" -exec sha256sum {} \;) \
> "${STAGING_DIR}/signatures/bundle.sha256sums"
# 8. Generate manifest
stellaops-bundler manifest create \
--bundle-dir "${STAGING_DIR}" \
--bundle-id "${BUNDLE_DIR}" \
--output "${STAGING_DIR}/manifest.json"
# 9. Sign bundle (if signing key available)
if [ -n "${SIGNING_KEY:-}" ]; then
echo "Signing bundle..."
stellaops-bundler sign \
--manifest "${STAGING_DIR}/manifest.json" \
--key "${SIGNING_KEY}" \
--output "${STAGING_DIR}/signatures/bundle.dsse.json"
fi
# 10. Create tarball
echo "Creating tarball..."
tar -C "$(dirname "${STAGING_DIR}")" -czf "/var/stellaops/bundles/${BUNDLE_DIR}.tar.gz" \
"$(basename "${STAGING_DIR}")"
echo "Bundle created: /var/stellaops/bundles/${BUNDLE_DIR}.tar.gz"
echo "Size: $(du -h /var/stellaops/bundles/${BUNDLE_DIR}.tar.gz | cut -f1)"
# 11. Verify bundle
stellaops-bundler verify "/var/stellaops/bundles/${BUNDLE_DIR}.tar.gz"
```
**Cron Schedule**:
```cron
# Daily at 01:00 UTC (after FIRST publishes EPSS at ~00:00 UTC)
0 1 * * * /opt/stellaops/scripts/create-risk-bundle.sh >> /var/log/stellaops/bundler.log 2>&1
```
---
## 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**:

## 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
}
```
---
## Appendix: Bundle Creation Tools
### stellaops-bundler CLI Reference
```bash
# Create EPSS metadata
stellaops-bundler epss metadata \
--file epss_scores-2025-12-17.csv.zst \
--model-date 2025-12-17 \
--output epss_metadata.json
# Create manifest
stellaops-bundler manifest create \
--bundle-dir risk-bundle-2025-12-17 \
--bundle-id risk-bundle-2025-12-17 \
--output manifest.json
# Sign bundle
stellaops-bundler sign \
--manifest manifest.json \
--key /path/to/signing-key.pem \
--output bundle.dsse.json
# Verify bundle
stellaops-bundler verify risk-bundle-2025-12-17.tar.gz
```
### Custom Bundle Scripts
Example for creating weekly bundles (7-day snapshots):
```bash
#!/bin/bash
# create-weekly-bundle.sh
WEEK_START=$(date -u -d "last monday" +%Y-%m-%d)
WEEK_END=$(date -u +%Y-%m-%d)
BUNDLE_ID="risk-bundle-weekly-${WEEK_START}"
echo "Creating weekly bundle: ${BUNDLE_ID}"
for day in $(seq 0 6); do
CURRENT_DATE=$(date -u -d "${WEEK_START} + ${day} days" +%Y-%m-%d)
# Fetch EPSS for each day...
curl -sL "https://epss.empiricalsecurity.com/epss_scores-${CURRENT_DATE}.csv.gz" \
-o "epss/epss_scores-${CURRENT_DATE}.csv.gz"
done
# Compress and bundle...
tar -czf "${BUNDLE_ID}.tar.gz" epss/ kev/ manifest.json
```

# 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,
"merklePath": true,
"rekorInclusion": null
}
}
],
"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.

# 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 \
--output /path/to/offline-bundle \
--include-feeds nvd,osv,epss \
--feed-date 2025-01-15
# Include SBOMs for known artifacts
stellaops offline sbom generate \
--artifact registry.example.com/app:v1 \
--artifact registry.example.com/app:v2 \
--output /path/to/offline-bundle/sboms
# Package for transfer
stellaops offline kit package \
--input /path/to/offline-bundle \
--output stellaops-offline-2025-01-15.tar.gz \
--sign
```
### 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:
# ═══════════════════════════════════════════

```
## Bundle Format Specification
### manifest.json
```json
{
"version": "1.0",
"type": "triage-bundle",
"created_at": "2025-01-15T10:00:00Z",
"scan_id": "scan-12345678",
"finding_count": 25,
"feed_snapshot": "sha256:abc123...",
"graph_revision": "sha256:def456...",
"signatures": {
"manifest": "sha256:ghi789...",
"dsse_envelope": "signature.dsse"
}
}
```
### Decision Format
```json
{
"finding_id": "finding-12345678",
"vuln_key": "CVE-2024-1234:pkg:npm/lodash@4.17.20",
"status": "not_affected",
"justification": "Code path gated by feature flag",
"reviewer": "security-team",
"decided_at": "2025-01-15T14:30:00Z",
"replay_token": "rt_abc123...",
"evidence_refs": [
"evidence/reachability/CVE-2024-1234.json"
]
}
```
## 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
```

# 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
---

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)
---
## Endpoints
### 1. Create Scan with Manifest
**POST** `/api/v1/scanner/scans`
**Description**: Creates a new scan with deterministic manifest.

# 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) |

"scanId": "scan-12345678-abcd",
"manifestHash": "sha256:def456...",
"sbomHash": "sha256:aaa111...",
"rulesHash": "sha256:bbb222...",
"feedHash": "sha256:ccc333...",

}
```
### Get Proof Bundle
```http
GET /api/v1/scans/{scanId}/proof-bundle
```
Downloads the proof bundle (ZIP archive) for a scan.
#### Response
Returns `application/zip` with the proof bundle containing:
- `manifest.json` - Signed scan manifest
- `ledger.json` - Proof ledger nodes
- `sbom.json` - Input SBOM (hash-verified)
- `findings.json` - Scored findings
- `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'
```

```
## 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)
```

## 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

# 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 \
--input smart-diff-wii.json \
--predicate-type smart-diff-wii@v1
```

# 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)
- Integration with Notify for tier-gated alerts (new)
No contradictions with existing implementations found.

# Only tainted_sink findings
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;
```

# Corpus Contribution Guide
**Sprint:** SPRINT_3500_0003_0001
**Task:** CORPUS-014 - Document corpus contribution guide
## 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
```
datasets/reachability/
├── corpus.json # Index of all samples
├── schemas/
│ └── corpus-sample.v1.json # JSON schema for samples
├── samples/
│ ├── gt-0001/ # Sample directory
│ │ ├── sample.json # Sample metadata
│ │ ├── expected.json # Expected findings
│ │ ├── sbom.json # Input SBOM
│ │ └── source/ # Optional source files
│ └── ...
└── baselines/
└── v1.0.0.json # Baseline metrics
```
## Sample Format
### sample.json
```json
{
"id": "gt-0001",
"name": "Python SQL Injection - Reachable",
"description": "Flask app with reachable SQL injection via user input",
"language": "python",
"ecosystem": "pypi",
"scenario": "webapi",
"entrypoints": ["app.py:main"],
"reachability_tier": "tainted_sink",
"created_at": "2025-01-15T00:00:00Z",
"author": "security-team",
"tags": ["sql-injection", "flask", "reachable"]
}
```
### expected.json
```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
```

# Scanner Schema Specification
**Schema**: `scanner`
**Owner**: Scanner.WebService
**Purpose**: Scan orchestration, call-graphs, proof bundles, reachability analysis
**Sprint**: SPRINT_3500_0002_0001, SPRINT_3500_0003_0002
---
## Overview
The `scanner` schema contains all tables related to:
1. Scan manifests and deterministic replay
2. Proof bundles (content-addressed storage metadata)
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
---

**Constraints**:
- `kind` must be 1 (static) or 2 (heuristic)
- `reason` must be in range 1-10 (enum defined in code)
- `weight` must be in range [0.0, 1.0]
**Partitioning**: Hash partition by `scan_id` (for scans with >500k edges)
**Retention**: 90 days
**Notes**:
- High-volume table (1M+ rows per large scan)
- Use partial indexes for `kind` to optimize static-only queries
- Consider GIN index on `(from_node_id, to_node_id)` for bidirectional BFS
---

## 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

``` ### 6.3 Plugin-specific mitigations (SEC5.PLG)
Without this step the embedded server fails to launch on OpenSSL 3 systems, causing timeouts in `StandardUserCredentialStoreTests`. - Bootstrap seed users default to `RequirePasswordReset = true`. `StandardUserCredentialStore.EnsureBootstrapUserAsync` enforces the configured password policy, rejects partial credentials, and emits `authority.plugin.load` telemetry so operators can prove who seeded the initial principals.
- Password policy overrides are validated against a built-in baseline (min length 12 + mixed character classes). The registrar now logs a structured warning whenever a deployment attempts to weaken those defaults, giving security reviewers an audit breadcrumb and satisfying the SEC5.PLG threat-model requirement.
### 6.3 Plugin-specific mitigations (SEC5.PLG) - All bootstrap and password operations use `ICryptoProvider` + Argon2id; legacy PBKDF2 hashes are upgraded inline and tagged via `plugin.rehashed`. Document any deviations so downstream plug-ins (or auditors) can reason about entropy expectations.
- Lockout metadata is deterministic: `plugin.lockout_until` + `plugin.retry_after_seconds` form the authoritative signal for incident response, and their presence is now noted in the Authority threat model (`docs/security/authority-threat-model.md`).
- Bootstrap seed users default to `RequirePasswordReset = true`. `StandardUserCredentialStore.EnsureBootstrapUserAsync` enforces the configured password policy, rejects partial credentials, and emits `authority.plugin.load` telemetry so operators can prove who seeded the initial principals. - When extending the Standard plug-in (or authoring a new one), keep these mitigations intact: enforce baseline policies, require explicit password reset flags on bootstrap flows, and emit the audit properties listed above. Third‑party plugins are expected to follow the same contract before they can advertise `SupportsPassword` or `SupportsBootstrap`.

- Lockout metadata is deterministic: `plugin.lockout_until` + `plugin.retry_after_seconds` form the authoritative signal for incident response, and their presence is now noted in the Authority threat model (`docs/security/authority-threat-model.md`).
- When extending the Standard plug-in (or authoring a new one), keep these mitigations intact: enforce baseline policies, require explicit password reset flags on bootstrap flows, and emit the audit properties listed above. Third‑party plugins are expected to follow the same contract before they can advertise `SupportsPassword` or `SupportsBootstrap`. - **Mutual TLS & trust stores.** `security.requireTls=true` enforces LDAPS/start‑TLS; set `security.requireClientCertificate=true` to demand mutual TLS. When that flag is enabled you must supply `connection.clientCertificate.pfxPath` + `passwordSecret`. Bundle CA chains under `connection.trustStore.bundlePath` and keep the files inside Offline Kit paths (`plugins/authority/ldap/**`) so air-gapped installs can import them without editing manifests.
- **DN‑to‑role mapping.** `claims.groupToRoleMap` is ideal for static DNs (e.g. `cn=stellaops-admins,...` → `operators`). Regex mappings let you project portions of the DN into role names: define `pattern` with named captures (`(?P<role>...)`) and use `{role}` placeholders in `roleFormat`. The enricher sorts all emitted roles, dedupes, and adds them as `ClaimTypes.Role`.
### 6.4 LDAP plug-in quick reference (PLG7.IMPL-005) - **Attribute pass-through.** `claims.extraAttributes` pairs the outgoing claim name with the LDAP attribute to read (first value wins). Only non-empty strings are written, which keeps audit/compliance data deterministic.
- **PostgreSQL claims cache.** `claims.cache.enabled=true` wires the `PostgresLdapClaimsCache` (default table `ldap_claims_cache_<pluginName>`). Set `ttlSeconds` according to your directory freshness SLA and adjust `maxEntries` to cap disk usage; eviction is deterministic (oldest entries removed first). Offline Kit bundles now include the table name requirements so replicas can pre-create tables.
- **Mutual TLS & trust stores.** `security.requireTls=true` enforces LDAPS/start‑TLS; set `security.requireClientCertificate=true` to demand mutual TLS. When that flag is enabled you must supply `connection.clientCertificate.pfxPath` + `passwordSecret`. Bundle CA chains under `connection.trustStore.bundlePath` and keep the files inside Offline Kit paths (`plugins/authority/ldap/**`) so air-gapped installs can import them without editing manifests. - **Client provisioning audit mirror.** `clientProvisioning.auditMirror.enabled=true` persists every LDAP write into PostgreSQL (`ldap_client_provisioning_<plugin>` table by default) with `{operation, dn, tenant, project, secretHash}`. That mirror is shipped in Offline Kits so regulators can diff LDAP state even without directory access. When `clientProvisioning.enabled=false`, the registrar logs a warning and downgrades the capability at runtime.
- **DN‑to‑role mapping.** `claims.groupToRoleMap` is ideal for static DNs (e.g. `cn=stellaops-admins,...` → `operators`). Regex mappings let you project portions of the DN into role names: define `pattern` with named captures (`(?P<role>...)`) and use `{role}` placeholders in `roleFormat`. The enricher sorts all emitted roles, dedupes, and adds them as `ClaimTypes.Role`. - **Bootstrap seeding + audits.** `bootstrap.*` mirrors the provisioning contract for human operators: the plug-in writes `uid={username}` entries under `bootstrap.containerDn`, applies `staticAttributes` placeholders (`{username}`, `{displayName}`), and mirrors deterministic audit records to PostgreSQL (`ldap_bootstrap_<plugin>` table by default) with hashed secrets (`AuthoritySecretHasher`). Bootstrap only lights up when (1) the manifest advertises the capability, (2) `bootstrap.enabled=true`, **and** (3) the plug-in proves the bind account can add/delete under the configured container. Otherwise the capability is silently downgraded and health checks surface `capabilities=bootstrapDisabled`.
- **Attribute pass-through.** `claims.extraAttributes` pairs the outgoing claim name with the LDAP attribute to read (first value wins). Only non-empty strings are written, which keeps audit/compliance data deterministic. - **Capability proofing.** On startup the plug-in performs a short-lived LDAP write probe (add→delete) inside each configured container. If either probe fails, the respective capability (`clientProvisioning`, `bootstrap`) is removed, `ClientProvisioning` stays `null`, and `CheckHealthAsync` reports `Degraded` until permissions are restored. This keeps read-only deployments safe while making it obvious when operators still need to grant write scope.
- **Mongo claims cache.** `claims.cache.enabled=true` wires the `MongoLdapClaimsCache` (default collection `ldap_claims_cache_<pluginName>`). Set `ttlSeconds` according to your directory freshness SLA and adjust `maxEntries` to cap disk usage; eviction is deterministic (oldest entries removed first). Offline Kit bundles now include the collection name requirements so replicas can pre-create capped collections. - **Sample manifest + binaries.** The curated manifest lives at `etc/authority.plugins/ldap.yaml` and demonstrates TLS, regex mappings, caching, and audit mirror options. Offline Kits copy both the manifest and the compiled plug-in into `plugins/authority/StellaOps.Authority.Plugin.Ldap/` so operators can drop them straight into air-gapped composer deployments.
- **Client provisioning audit mirror.** `clientProvisioning.auditMirror.enabled=true` persists every LDAP write into Mongo (`ldap_client_provisioning_<plugin>` by default) with `{operation, dn, tenant, project, secretHash}`. That mirror is shipped in Offline Kits so regulators can diff LDAP state even without directory access. When `clientProvisioning.enabled=false`, the registrar logs a warning and downgrades the capability at runtime.
- **Bootstrap seeding + audits.** `bootstrap.*` mirrors the provisioning contract for human operators: the plug-in writes `uid={username}` entries under `bootstrap.containerDn`, applies `staticAttributes` placeholders (`{username}`, `{displayName}`), and mirrors deterministic audit documents to Mongo (`ldap_bootstrap_<plugin>` by default) with hashed secrets (`AuthoritySecretHasher`). Bootstrap only lights up when (1) the manifest advertises the capability, (2) `bootstrap.enabled=true`, **and** (3) the plug-in proves the bind account can add/delete under the configured container. Otherwise the capability is silently downgraded and health checks surface `capabilities=bootstrapDisabled`. ## 7. Configuration & Secrets
- **Capability proofing.** On startup the plug-in performs a short-lived LDAP write probe (add→delete) inside each configured container. If either probe fails, the respective capability (`clientProvisioning`, `bootstrap`) is removed, `ClientProvisioning` stays `null`, and `CheckHealthAsync` reports `Degraded` until permissions are restored. This keeps read-only deployments safe while making it obvious when operators still need to grant write scope. - Authority looks for manifests under `etc/authority.plugins/`. Each YAML file maps directly to a plug-in name.
- **Sample manifest + binaries.** The curated manifest lives at `etc/authority.plugins/ldap.yaml` and demonstrates TLS, regex mappings, caching, and audit mirror options. Offline Kits copy both the manifest and the compiled plug-in into `plugins/authority/StellaOps.Authority.Plugin.Ldap/` so operators can drop them straight into air-gapped composer deployments. - Support environment overrides using `STELLAOPS_AUTHORITY_PLUGINS__DESCRIPTORS__<NAME>__...`.
- Never store raw secrets in git: allow operators to supply them via `.local.yaml`, environment variables, or injected secret files. Document which keys are mandatory.

# EPSS v4 Integration Guide
## Overview
EPSS (Exploit Prediction Scoring System) v4 is a machine learning-based vulnerability scoring system developed by FIRST.org that predicts the probability a CVE will be exploited in the wild within the next 30 days. StellaOps integrates EPSS as a **probabilistic threat signal** alongside CVSS v4's **deterministic severity assessment**, enabling more accurate vulnerability prioritization.
**Key Concepts**:
- **EPSS Score**: Probability (0.0-1.0) that a CVE will be exploited in next 30 days
- **EPSS Percentile**: Ranking (0.0-1.0) of this CVE relative to all scored CVEs
- **Model Date**: Date for which EPSS scores were computed
- **Immutable at-scan**: EPSS evidence captured at scan time never changes (deterministic replay)
- **Current EPSS**: Live projection for triage (updated daily)
---
## How EPSS Works
EPSS uses machine learning to predict exploitation probability based on:
1. **Vulnerability Characteristics**: CVSS metrics, CWE, affected products
2. **Social Signals**: Twitter/GitHub mentions, security blog posts
3. **Exploit Database Entries**: Exploit-DB, Metasploit, etc.
4. **Historical Exploitation**: Past exploitation patterns
EPSS is updated **daily** by FIRST.org based on fresh threat intelligence.
### EPSS vs CVSS
| Dimension | CVSS v4 | EPSS v4 |
|-----------|---------|---------|
| **Nature** | Deterministic severity | Probabilistic threat |
| **Scale** | 0.0-10.0 (severity) | 0.0-1.0 (probability) |
| **Update Frequency** | Static (per CVE version) | Daily (live threat data) |
| **Purpose** | Impact assessment | Likelihood assessment |
| **Source** | Vendor/NVD | FIRST.org ML model |
**Example**:
- **CVE-2024-1234**: CVSS 9.8 (Critical) + EPSS 0.01 (1st percentile)
- Interpretation: Severe impact if exploited, but very unlikely to be exploited
- Priority: **Medium** (deprioritize despite high CVSS)
- **CVE-2024-5678**: CVSS 6.5 (Medium) + EPSS 0.95 (98th percentile)
- Interpretation: Moderate impact, but actively being exploited
- Priority: **High** (escalate despite moderate CVSS)

## Daily Operation
### Automated Ingestion
EPSS data is ingested automatically daily at **00:05 UTC** via Scheduler.
**Workflow**:
1. Scheduler triggers `epss.ingest` job at 00:05 UTC
2. Concelier downloads `epss_scores-YYYY-MM-DD.csv.gz` from FIRST.org
3. CSV parsed (comment line → metadata, rows → scores)
4. Bulk insert into `epss_scores` partition (NpgsqlBinaryImporter)
5. Compute delta: `epss_changes` (compare vs `epss_current`)
6. Upsert `epss_current` (latest projection)
7. Emit `epss.updated` event
8. Enrichment job updates impacted vulnerability instances
9. Notifications sent if priority bands changed
**Monitoring**:
```bash
# Check latest model date
stellaops epss status
# Output:
# EPSS Status:
# Latest Model Date: 2025-12-16
# Import Time: 2025-12-17 00:07:32 UTC
# CVE Count: 231,417
# Staleness: FRESH (1 day)
```
### Manual Triggering
```bash
# Trigger manual ingest (force re-import)
stellaops concelier job trigger epss.ingest --date 2025-12-16 --force
# Backfill historical data (last 30 days)
stellaops epss backfill --from 2025-11-17 --to 2025-12-16
```

## Scanner Integration
### EPSS Evidence in Scan Findings
Every scan finding includes **immutable EPSS-at-scan** evidence:

"delta_score": 0.02766,
"delta_percentile": 0.01222,
"trend": "RISING"
}
}
}
```
**Key Points**:
- **epss_at_scan**: Immutable, captured at scan time (deterministic replay)
- **epss_current**: Mutable, updated daily for live triage
- **Replay**: Historical scans always use `epss_at_scan` for consistent policy evaluation
### Bulk Query Optimization
Scanner queries EPSS for all CVEs in a single database call:
```sql
SELECT cve_id, epss_score, percentile, model_date, import_run_id
FROM concelier.epss_current
WHERE cve_id = ANY(@cve_ids);
```
**Performance**: <500ms for 10k CVEs (P95)

## Policy Engine Integration
### Risk Score Formula
**Simple Profile**:
```
risk_score = (cvss_base / 10) + epss_bonus + kev_bonus
```
**EPSS Bonus Table**:
| EPSS Percentile | Bonus | Rationale |
|----------------|-------|-----------|
| ≥99th | +10% | Top 1% most likely to be exploited |
| ≥90th | +5% | Top 10% high exploitation probability |
| ≥50th | +2% | Above median moderate risk |
| <50th | 0% | Below median no bonus |
**Advanced Profile**:
Adds:
- **KEV synergy**: If in KEV catalog → multiply EPSS bonus by 1.5
- **Uncertainty penalty**: Missing EPSS → -5%
- **Temporal decay**: EPSS >30 days stale → reduce bonus by 50%
### VEX Lattice Rules
**Escalation**:
- **SR (Static Reachable) + EPSS≥90th** → Auto-escalate to **CR (Confirmed Reachable)**
- Rationale: High exploit probability warrants confirmation
**Review Flags**:
- **DV (Denied by Vendor VEX) + EPSS≥95th** → Flag for manual review
- Rationale: Vendor denial contradicted by active exploitation signals
**Prioritization**:
- **U (Unknown) + EPSS≥95th** → Prioritize for reachability analysis
- Rationale: High exploit probability justifies effort

## Troubleshooting
### EPSS Data Not Available
**Symptom**: Scans show "EPSS: N/A"
**Diagnosis**:
```bash
# Check EPSS status
stellaops epss status
# Check import runs
stellaops concelier jobs list --type epss.ingest --limit 10
```
**Resolution**:
1. **No imports**: Trigger manual ingest
```bash
stellaops concelier job trigger epss.ingest
```
2. **Import failed**: Check logs
```bash
stellaops concelier logs --job-id <id> --level ERROR
```
3. **FIRST.org down**: Use air-gapped bundle
```bash
stellaops offline import --bundle /path/to/risk-bundle.tar.zst
```
### Stale EPSS Data
**Symptom**: UI shows "EPSS stale (14 days)"
**Diagnosis**:
```sql
SELECT * FROM concelier.epss_model_staleness;
-- Output: days_stale: 14, staleness_status: STALE
```
**Resolution**:
1. **Online**: Check scheduler job status
```bash
stellaops scheduler jobs status epss.ingest
```
2. **Air-gapped**: Import fresh bundle
```bash
stellaops offline import --bundle /path/to/latest-bundle.tar.zst
```
3. **Fallback**: Disable EPSS temporarily (uses CVSS-only)
```yaml
# etc/scanner.yaml
scanner:
epss:
enabled: false
```
### High Memory Usage During Ingest
**Symptom**: Concelier worker OOM during EPSS ingest
**Diagnosis**:
```bash
# Check memory metrics
stellaops metrics query 'process_resident_memory_bytes{service="concelier"}'
```
**Resolution**:
1. **Increase worker memory limit**:
```yaml
# Kubernetes deployment
resources:
limits:
memory: 1Gi # Was 512Mi
```
2. **Verify streaming parser** (should not load full CSV into memory):
```bash
# Check logs for "EPSS CSV parsed: rows_yielded="
stellaops concelier logs --job-type epss.ingest | grep "CSV parsed"
```
---
## Best Practices
### 1. Combine Signals (Never Use EPSS Alone)
❌ **Don't**: `if epss > 0.95 then CRITICAL`
✅ **Do**: `if cvss >= 8.0 AND epss >= 0.95 AND runtime_exposed then CRITICAL`
### 2. Review High EPSS Manually
Manually review vulnerabilities with EPSS ≥95th percentile, especially if:
- CVSS is low (<7.0) but EPSS is high
- Vendor VEX denies exploitability but EPSS is high
### 3. Track Trends
Monitor EPSS changes over time:
- Rising EPSS → increasing threat
- Falling EPSS → threat subsiding
### 4. Update Regularly
- **Online**: Daily (automatic)
- **Air-gapped**: Weekly minimum, daily preferred
### 5. Verify During Audits
For compliance audits, use EPSS-at-scan (immutable) not current EPSS:
```sql
SELECT epss_score_at_scan, epss_model_date_at_scan
FROM scan_findings
WHERE scan_id = 'audit-scan-20251217';
```

# Implementation Plan 3410: EPSS v4 Integration with CVSS v4 Framework
## Overview
This implementation plan delivers **EPSS (Exploit Prediction Scoring System) v4** integration into StellaOps as a probabilistic threat signal alongside CVSS v4's deterministic severity assessment. EPSS provides daily-updated exploitation probability scores (0.0-1.0) from FIRST.org, transforming vulnerability prioritization from static severity to live risk intelligence.
**Plan ID:** IMPL_3410
**Advisory Reference:** `docs/product-advisories/unprocessed/16-Dec-2025 - Merging EPSS v4 with CVSS v4 Frameworks.md`
**Created:** 2025-12-17
**Status:** APPROVED
**Target Completion:** Q2 2026
---
## Executive Summary
### Business Value
EPSS integration provides:
1. **Reduced False Positives**: CVSS 9.8 + EPSS 0.01 → deprioritize (theoretically severe but unlikely to exploit)
2. **Surface Active Threats**: CVSS 6.5 + EPSS 0.95 → urgent (moderate severity but active exploitation)
3. **Competitive Moat**: Few platforms merge EPSS into reachability lattice decisions
4. **Offline Parity**: Air-gapped deployments get EPSS snapshots → sovereign compliance advantage
5. **Deterministic Replay**: EPSS-at-scan immutability preserves audit trail
### Architectural Fit
**90% alignment** with StellaOps' existing architecture:
- ✅ **Append-only time-series** → fits Aggregation-Only Contract (AOC)
- ✅ **Immutable evidence at scan** → aligns with proof chain
- ✅ **PostgreSQL as truth** → existing pattern
- ✅ **Valkey as optional cache** → existing pattern
- ✅ **Outbox event-driven** → existing pattern
- ✅ **Deterministic replay** → model_date tracking ensures reproducibility
### Effort & Timeline
| Phase | Sprints | Tasks | Weeks | Priority |
|-------|---------|-------|-------|----------|
| **Phase 1: MVP** | 3 | 37 | 4-6 | **P1** |
| **Phase 2: Enrichment** | 3 | 38 | 4 | **P2** |
| **Phase 3: Advanced** | 3 | 31 | 4 | **P3** |
| **TOTAL** | **9** | **106** | **12-14** | - |
**Recommended Path**:
- **Q1 2026**: Phase 1 (Ingestion + Scanner + UI) → ship as "EPSS Preview"
- **Q2 2026**: Phase 2 (Enrichment + Notifications + Policy) → GA
- **Q3 2026**: Phase 3 (Analytics + API) → optional, customer-driven

### Data Flow Principles
1. **Immutability at Source**: `epss_scores` is append-only; never update/delete
2. **Deterministic Replay**: Every scan stores `epss_model_date + import_run_id` → reproducible
3. **Dual Projections**:
- **At-scan evidence** (immutable) → audit trail, replay
- **Current EPSS** (mutable triage) → live prioritization
4. **Event-Driven Enrichment**: Only update instances when EPSS materially changes
5. **Offline Parity**: Air-gapped bundles include EPSS snapshots with same schema

## Risk Assessment
| Risk | Likelihood | Impact | Mitigation |
|------|------------|--------|------------|
| **EPSS noise → notification fatigue** | HIGH | MEDIUM | Flag-based filtering, `BigJumpDelta` threshold, digest mode |
| **FIRST.org downtime** | LOW | MEDIUM | Exponential backoff, air-gapped bundles, optional mirror to own CDN |
| **User conflates EPSS with CVSS** | MEDIUM | HIGH | Clear UI labels ("Exploit Likelihood" vs "Severity"), explain text, docs |
| **PostgreSQL storage growth** | LOW | LOW | Monthly partitions, roll-up after 180 days, ZSTD compression |
| **Implementation delays other priorities** | MEDIUM | HIGH | MVP-first (Phase 1 only), parallel sprints, optional Phase 3 |
| **Air-gapped staleness degrades value** | MEDIUM | MEDIUM | Weekly bundle updates, staleness warnings, fallback to CVSS-only |
| **EPSS coverage gaps (5% CVEs)** | LOW | LOW | Unknown handling (not zero), KEV fallback, uncertainty signal |
| **Schema drift (FIRST changes CSV)** | LOW | HIGH | Comment line parser flexibility, schema version tracking, alerts on parse failures |

# Router Rate Limiting - Master Sprint Tracker
**IMPLID:** 1200 (Router infrastructure)
**Feature:** Centralized rate limiting for Stella Router as standalone product
**Advisory Source:** `docs/product-advisories/unprocessed/15-Dec-2025 - Designing 202 + Retry‑After Backpressure Control.md`
**Owner:** Router Team
**Status:** PLANNING → READY FOR IMPLEMENTATION
**Priority:** HIGH - Core feature for Router product
**Target Completion:** 6 weeks (4 weeks implementation + 2 weeks rollout)
---
## Executive Summary
Implement centralized, multi-dimensional rate limiting in Stella Router to:
1. Eliminate per-service rate limiting duplication (architectural cleanup)
2. Enable Router as standalone product with intelligent admission control
3. Provide sophisticated protection (dual-scope, dual-window, rule stacking)
4. Support complex configuration matrices (instance, environment, microservice, route)
**Key Principle:** Rate limiting is a router responsibility. Microservices should NOT implement bare HTTP rate limiting.
---
## Architecture Overview
### Dual-Scope Design
**for_instance (In-Memory):**
- Protects individual router instance from local overload
- Zero latency (sub-millisecond)
- Sliding window counters
- No network dependencies
**for_environment (Valkey-Backed):**
- Protects entire environment across all router instances
- Distributed coordination via Valkey (Redis fork)
- Fixed-window counters with atomic Lua operations
- Circuit breaker for resilience
### Multi-Dimensional Configuration
```
Global Defaults
└─> Per-Environment
└─> Per-Microservice
└─> Per-Route (most specific wins)
```
### Rule Stacking
Each target can have multiple rules (AND logic):
- Example: "10 req/sec AND 3000 req/hour AND 50k req/day"
- All rules must pass
- Most restrictive Retry-After returned
---
## Sprint Breakdown
| Sprint | IMPLID | Duration | Focus | Status |
|--------|--------|----------|-------|--------|
| **Sprint 1** | 1200_001_001 | 5-7 days | Core router rate limiting | DONE |
| **Sprint 2** | 1200_001_002 | 2-3 days | Per-route granularity | TODO |
| **Sprint 3** | 1200_001_003 | 2-3 days | Rule stacking (multiple windows) | TODO |
| **Sprint 4** | 1200_001_004 | 3-4 days | Service migration (AdaptiveRateLimiter) | TODO |
| **Sprint 5** | 1200_001_005 | 3-5 days | Comprehensive testing | TODO |
| **Sprint 6** | 1200_001_006 | 2 days | Documentation & rollout prep | TODO |
**Total Implementation:** 17-24 days
**Rollout (Post-Implementation):**
- Week 1: Shadow mode (metrics only, no enforcement)
- Week 2: Soft limits (2x traffic peaks)
- Week 3: Production limits
- Week 4+: Service migration complete
---
## Dependencies
### External
- Valkey/Redis cluster (≥7.0) for distributed state
- OpenTelemetry SDK for metrics
- StackExchange.Redis NuGet package
### Internal
- `StellaOps.Router.Gateway` library (existing)
- Routing metadata (microservice + route identification)
- Configuration system (YAML binding)
### Migration Targets
- `AdaptiveRateLimiter` in Orchestrator (extract TokenBucket, HourlyCounter configs)
---
## Key Design Decisions
### 1. Status Codes
- ✅ **429 Too Many Requests** for rate limiting (NOT 503, NOT 202)
- ✅ **Retry-After** header (seconds or HTTP-date)
- ✅ JSON response body with details
### 2. Terminology
- ✅ **Valkey** (not Redis) - consistent with StellaOps naming
- ✅ Snake_case in YAML configs
- ✅ PascalCase in C# code
### 3. Configuration Philosophy
- Support complex matrices (required for Router product)
- Sensible defaults at every level
- Clear inheritance semantics
- Fail-fast validation on startup
### 4. Performance Targets
- Instance check: <1ms P99 latency
- Environment check: <10ms P99 latency (including Valkey RTT)
- Router throughput: 100k req/sec with rate limiting enabled
- Valkey load: <1000 ops/sec per router instance
### 5. Resilience
- Circuit breaker for Valkey failures (fail-open)
- Activation gate to skip Valkey under low traffic
- Instance limits enforced even if Valkey is down
---
## Success Criteria
### Functional
- [ ] Router enforces per-instance limits (in-memory)
- [ ] Router enforces per-environment limits (Valkey-backed)
- [ ] Per-microservice configuration works
- [ ] Per-route configuration works
- [ ] Multiple rules per target work (rule stacking)
- [ ] 429 + Retry-After returned correctly
- [ ] Circuit breaker handles Valkey failures gracefully
- [ ] Activation gate reduces Valkey load by 80%+ under low traffic
### Performance
- [ ] Instance check <1ms P99
- [ ] Environment check <10ms P99
- [ ] 100k req/sec throughput maintained
- [ ] Valkey load <1000 ops/sec per instance
### Operational

- [ ] Dashboards created (Grafana)
- [ ] Alerts configured
- [ ] Documentation complete
- [ ] Migration from service-level rate limiters complete
### Quality
- [ ] Unit test coverage >90%
- [ ] Integration tests for all config combinations
- [ ] Load tests (k6 scenarios A-F)
- [ ] Failure injection tests

# Sprint 2: Per-Route Granularity
**IMPLID:** 1200_001_002
**Sprint Duration:** 2-3 days
**Priority:** HIGH
**Dependencies:** Sprint 1 (Core implementation)
**Blocks:** Sprint 5 (Testing needs routes)
---
## Sprint Goal
Extend rate limiting configuration to support per-route limits with pattern matching and inheritance resolution.
**Acceptance Criteria:**
- Routes can have specific rate limits
- Route patterns support exact match, prefix, and regex
- Inheritance works: route → microservice → environment → global
- Most specific route wins
- Configuration validated on startup
---
## Working Directory
`src/__Libraries/StellaOps.Router.Gateway/RateLimit/`
---
## Task Breakdown
### Task 2.1: Extend Configuration Models (0.5 days)
**Goal:** Add routes section to configuration schema.
**Files to Modify:**
1. `RateLimit/Models/MicroserviceLimitsConfig.cs` - Add Routes property
2. `RateLimit/Models/RouteLimitsConfig.cs` - NEW: Route-specific limits
**Implementation:**
```csharp
// RouteLimitsConfig.cs (NEW)
namespace StellaOps.Router.Gateway.RateLimit.Models;
public sealed class RouteLimitsConfig
{
/// <summary>
/// Route pattern: exact ("/api/scans"), prefix ("/api/scans/*"), or regex ("^/api/scans/[a-f0-9-]+$")
/// </summary>
[ConfigurationKeyName("pattern")]
public string Pattern { get; set; } = "";
[ConfigurationKeyName("match_type")]
public RouteMatchType MatchType { get; set; } = RouteMatchType.Exact;
[ConfigurationKeyName("per_seconds")]
public int? PerSeconds { get; set; }
[ConfigurationKeyName("max_requests")]
public int? MaxRequests { get; set; }
[ConfigurationKeyName("allow_burst_for_seconds")]
public int? AllowBurstForSeconds { get; set; }
[ConfigurationKeyName("allow_max_burst_requests")]
public int? AllowMaxBurstRequests { get; set; }
public void Validate(string path)
{
if (string.IsNullOrWhiteSpace(Pattern))
throw new ArgumentException($"{path}: pattern is required");
// Both long settings must be set or both omitted
if ((PerSeconds.HasValue) != (MaxRequests.HasValue))
throw new ArgumentException($"{path}: per_seconds and max_requests must both be set or both omitted");
// Both burst settings must be set or both omitted
if ((AllowBurstForSeconds.HasValue) != (AllowMaxBurstRequests.HasValue))
throw new ArgumentException($"{path}: Burst settings must both be set or both omitted");
if (PerSeconds < 0 || MaxRequests < 0)
throw new ArgumentException($"{path}: Values must be >= 0");
// Validate regex pattern if applicable
if (MatchType == RouteMatchType.Regex)
{
try
{
_ = new Regex(Pattern, RegexOptions.Compiled);
}
catch (Exception ex)
{
throw new ArgumentException($"{path}: Invalid regex pattern: {ex.Message}");
}
}
}
}
public enum RouteMatchType
{
Exact, // Exact path match: "/api/scans"
Prefix, // Prefix match: "/api/scans/*"
Regex // Regex match: "^/api/scans/[a-f0-9-]+$"
}
// Update MicroserviceLimitsConfig.cs to add:
public sealed class MicroserviceLimitsConfig
{
// ... existing properties ...
[ConfigurationKeyName("routes")]
public Dictionary<string, RouteLimitsConfig> Routes { get; set; }
= new(StringComparer.OrdinalIgnoreCase);
public void Validate(string path)
{
// ... existing validation ...
// Validate routes
foreach (var (name, config) in Routes)
{
if (string.IsNullOrWhiteSpace(name))
throw new ArgumentException($"{path}.routes: Empty route name");
config.Validate($"{path}.routes.{name}");
}
}
}
```
**Configuration Example:**
```yaml
for_environment:
microservices:
scanner:
per_seconds: 60
max_requests: 600
routes:
scan_submit:
pattern: "/api/scans"
match_type: exact
per_seconds: 10
max_requests: 50
scan_status:
pattern: "/api/scans/*"
match_type: prefix
per_seconds: 1
max_requests: 100
scan_by_id:
pattern: "^/api/scans/[a-f0-9-]+$"
match_type: regex
per_seconds: 1
max_requests: 50
```
**Testing:**
- Unit tests for route configuration loading
- Validation of route patterns
- Regex pattern validation
**Deliverable:** Extended configuration models with routes.
---
### Task 2.2: Route Matching Implementation (1 day)
**Goal:** Implement route pattern matching logic.
**Files to Create:**
1. `RateLimit/RouteMatching/RouteMatcher.cs` - Main matcher
2. `RateLimit/RouteMatching/IRouteMatcher.cs` - Matcher interface
3. `RateLimit/RouteMatching/ExactRouteMatcher.cs` - Exact match
4. `RateLimit/RouteMatching/PrefixRouteMatcher.cs` - Prefix match
5. `RateLimit/RouteMatching/RegexRouteMatcher.cs` - Regex match
**Implementation:**
```csharp
// IRouteMatcher.cs
public interface IRouteMatcher
{
bool Matches(string requestPath);

### Task 2.3: Inheritance Resolution (0.5 days)
**Goal:** Resolve effective limits from global → env → microservice → route.
**Files to Create:**
1. `RateLimit/LimitInheritanceResolver.cs` - Inheritance logic
**Implementation:**
```csharp
// LimitInheritanceResolver.cs
public sealed class LimitInheritanceResolver
{
private readonly RateLimitConfig _config;
public LimitInheritanceResolver(RateLimitConfig _config)
{
this._config = _config;
}
public EffectiveLimits ResolveForRoute(string microservice, string? routeName)
{
// Start with global defaults
var longWindow = 0;
var longMax = 0;
var burstWindow = 0;
var burstMax = 0;
// Layer 1: Global environment defaults
if (_config.ForEnvironment != null)
{
longWindow = _config.ForEnvironment.PerSeconds;
longMax = _config.ForEnvironment.MaxRequests;
burstWindow = _config.ForEnvironment.AllowBurstForSeconds;
burstMax = _config.ForEnvironment.AllowMaxBurstRequests;
}
// Layer 2: Microservice overrides
if (_config.ForEnvironment?.Microservices.TryGetValue(microservice, out var msConfig) == true)
{
if (msConfig.PerSeconds.HasValue)
{
longWindow = msConfig.PerSeconds.Value;
longMax = msConfig.MaxRequests!.Value;
}
if (msConfig.AllowBurstForSeconds.HasValue)
{
burstWindow = msConfig.AllowBurstForSeconds.Value;
burstMax = msConfig.AllowMaxBurstRequests!.Value;
}
// Layer 3: Route overrides (most specific)
if (!string.IsNullOrWhiteSpace(routeName) &&
msConfig.Routes.TryGetValue(routeName, out var routeConfig))
{
if (routeConfig.PerSeconds.HasValue)
{
longWindow = routeConfig.PerSeconds.Value;
longMax = routeConfig.MaxRequests!.Value;
}
if (routeConfig.AllowBurstForSeconds.HasValue)
{
burstWindow = routeConfig.AllowBurstForSeconds.Value;
burstMax = routeConfig.AllowMaxBurstRequests!.Value;
}
}
}
return EffectiveLimits.FromConfig(longWindow, longMax, burstWindow, burstMax);
}
}
```
**Testing:**
- Unit tests for inheritance resolution
- All combinations: global only, global + microservice, global + microservice + route
- Verify most specific wins
**Deliverable:** Correct limit inheritance.
---
### Task 2.4: Integrate Route Matching into RateLimitService (0.5 days)
**Goal:** Use route matcher in rate limit decision.
**Files to Modify:**
1. `RateLimit/RateLimitService.cs` - Add route resolution
**Implementation:**
```csharp
// Update RateLimitService.cs
public sealed class RateLimitService
{
private readonly RateLimitConfig _config;
private readonly InstanceRateLimiter _instanceLimiter;
private readonly EnvironmentRateLimiter? _environmentLimiter;
private readonly Dictionary<string, RouteMatcher> _routeMatchers; // Per microservice
private readonly LimitInheritanceResolver _inheritanceResolver;
private readonly ILogger<RateLimitService> _logger;
public RateLimitService(
RateLimitConfig config,
InstanceRateLimiter instanceLimiter,
EnvironmentRateLimiter? environmentLimiter,
ILogger<RateLimitService> logger)
{
_config = config;
_instanceLimiter = instanceLimiter;
_environmentLimiter = environmentLimiter;

// Build route matchers per microservice
_routeMatchers = new Dictionary<string, RouteMatcher>(StringComparer.OrdinalIgnoreCase);
if (config.ForEnvironment != null)
{
foreach (var (msName, msConfig) in config.ForEnvironment.Microservices)
{
if (msConfig.Routes.Count > 0)
{
var matcher = new RouteMatcher();
foreach (var (routeName, routeConfig) in msConfig.Routes)
{
matcher.AddRoute(routeName, routeConfig);
}
_routeMatchers[msName] = matcher;
}
}
}
}
public async Task<RateLimitDecision> CheckLimitAsync(
string microservice,
string requestPath,
CancellationToken cancellationToken)
{
// Resolve route
string? routeName = null;
if (_routeMatchers.TryGetValue(microservice, out var matcher))
{
var (matchedRoute, _) = matcher.FindBestMatch(requestPath);
routeName = matchedRoute;
}
// Check instance limits (always)
var instanceDecision = _instanceLimiter.TryAcquire(microservice);
if (!instanceDecision.Allowed)
{
return instanceDecision;
}
// Activation gate check
if (_config.ActivationThresholdPer5Min > 0)
{
var activationCount = _instanceLimiter.GetActivationCount();
if (activationCount < _config.ActivationThresholdPer5Min)
{
RateLimitMetrics.ValkeyCallSkipped();
return instanceDecision;
}
}
// Check environment limits
if (_environmentLimiter != null)
{
var limits = _inheritanceResolver.ResolveForRoute(microservice, routeName);
if (limits.Enabled)
{
var envDecision = await _environmentLimiter.TryAcquireAsync(
$"{microservice}:{routeName ?? "default"}", limits, cancellationToken);
if (envDecision.HasValue)
{
return envDecision.Value;
}
}
}
return instanceDecision;
}
}
```
**Update Middleware:**

public async Task InvokeAsync(HttpContext context)
{
var microservice = context.Items["RoutingTarget"] as string ?? "unknown";
var requestPath = context.Request.Path.Value ?? "/";
var decision = await _rateLimitService.CheckLimitAsync(
microservice, requestPath, context.RequestAborted);
RateLimitMetrics.RecordDecision(decision);
if (!decision.Allowed)
{
await WriteRateLimitResponse(context, decision);
return;
}
await _next(context);
}
```
**Testing:**
- Integration tests with different routes
- Verify route matching works in middleware
- Verify inheritance resolution
**Deliverable:** Route-aware rate limiting.
---
### Task 2.5: Documentation (1 day)
**Goal:** Document per-route configuration and examples.
**Files to Create:**
1. `docs/router/rate-limiting-routes.md` - Route configuration guide
**Content:**
```markdown
# Per-Route Rate Limiting
## Overview
Per-route rate limiting allows different API endpoints to have different rate limits, even within the same microservice.
## Configuration
Routes are configured under `microservices.<name>.routes`:
\`\`\`yaml
for_environment:
microservices:
scanner:
# Default limits for scanner
per_seconds: 60
max_requests: 600
# Per-route overrides
routes:
scan_submit:
pattern: "/api/scans"
match_type: exact
per_seconds: 10
max_requests: 50
\`\`\`
## Match Types
### Exact Match
Matches the exact path.
\`\`\`yaml
pattern: "/api/scans"
match_type: exact
\`\`\`
Matches: `/api/scans`
Does NOT match: `/api/scans/123`, `/api/scans/`
### Prefix Match
Matches any path starting with the prefix.
\`\`\`yaml
pattern: "/api/scans/*"
match_type: prefix
\`\`\`
Matches: `/api/scans/123`, `/api/scans/status`, `/api/scans/abc/def`
### Regex Match
Matches using regular expressions.
\`\`\`yaml
pattern: "^/api/scans/[a-f0-9-]+$"
match_type: regex
\`\`\`
Matches: `/api/scans/abc-123`, `/api/scans/00000000-0000-0000-0000-000000000000`
Does NOT match: `/api/scans/`, `/api/scans/invalid@chars`
## Specificity Rules
When multiple routes match, the most specific wins:
1. **Exact match** (highest priority)
2. **Prefix match** (longer prefix wins)
3. **Regex match** (lowest priority)
## Inheritance
Limits inherit from parent levels:
\`\`\`
Global Defaults
└─> Microservice Defaults
└─> Route Overrides (most specific)
\`\`\`
Routes can override:
- Long window limits only
- Burst window limits only
- Both
- Neither (inherits all from microservice)
## Examples
### Expensive vs Cheap Operations
\`\`\`yaml
scanner:
per_seconds: 60
max_requests: 600
routes:
scan_submit:
pattern: "/api/scans"
match_type: exact
per_seconds: 10
max_requests: 50 # Expensive: 50/10sec
scan_status:
pattern: "/api/scans/*"
match_type: prefix
per_seconds: 1
max_requests: 100 # Cheap: 100/sec
\`\`\`
### Read vs Write Operations
\`\`\`yaml
policy:
per_seconds: 60
max_requests: 300
routes:
policy_read:
pattern: "^/api/v1/policy/[^/]+$"
match_type: regex
per_seconds: 1
max_requests: 50 # Reads: 50/sec
policy_write:
pattern: "^/api/v1/policy/[^/]+$"
match_type: regex
per_seconds: 10
max_requests: 10 # Writes: 10/10sec
\`\`\`
\`\`\`
**Testing:**
- Review doc examples
- Verify config snippets
**Deliverable:** Complete route configuration guide.

## Task Breakdown
### Task 3.1: Extend Configuration for Rule Arrays (0.5 days)
**Goal:** Change single window config to array of rules.
**Files to Modify:**
1. `RateLimit/Models/InstanceLimitsConfig.cs` - Add Rules array
2. `RateLimit/Models/EnvironmentLimitsConfig.cs` - Add Rules array

4. `RateLimit/Models/RouteLimitsConfig.cs` - Add Rules array
**Files to Create:**
1. `RateLimit/Models/RateLimitRule.cs` - Single rule definition
**Implementation:**
```csharp
// RateLimitRule.cs (NEW)
namespace StellaOps.Router.Gateway.RateLimit.Models;
public sealed class RateLimitRule
{
[ConfigurationKeyName("per_seconds")]
public int PerSeconds { get; set; }
[ConfigurationKeyName("max_requests")]
public int MaxRequests { get; set; }
[ConfigurationKeyName("name")]
public string? Name { get; set; } // Optional: for debugging/metrics
public void Validate(string path)
{
if (PerSeconds <= 0)
throw new ArgumentException($"{path}: per_seconds must be > 0");
if (MaxRequests <= 0)
throw new ArgumentException($"{path}: max_requests must be > 0");
}
}
// Update InstanceLimitsConfig.cs
public sealed class InstanceLimitsConfig
{
// DEPRECATED (keep for backward compat, but rules takes precedence)
[ConfigurationKeyName("per_seconds")]
public int PerSeconds { get; set; }
[ConfigurationKeyName("max_requests")]
public int MaxRequests { get; set; }
[ConfigurationKeyName("allow_burst_for_seconds")]
public int AllowBurstForSeconds { get; set; }
[ConfigurationKeyName("allow_max_burst_requests")]
public int AllowMaxBurstRequests { get; set; }
// NEW: Array of rules
[ConfigurationKeyName("rules")]
public List<RateLimitRule> Rules { get; set; } = new();
public void Validate(string path)
{
// If rules specified, use those; otherwise fall back to legacy single-window config
if (Rules.Count > 0)
{
for (var i = 0; i < Rules.Count; i++)
{
Rules[i].Validate($"{path}.rules[{i}]");
}
}
else
{
// Legacy validation
if (PerSeconds < 0 || MaxRequests < 0)
throw new ArgumentException($"{path}: Window and limit must be >= 0");
}
}
public List<RateLimitRule> GetEffectiveRules()
{
if (Rules.Count > 0)
return Rules;
// Convert legacy config to rules
var legacy = new List<RateLimitRule>();
if (PerSeconds > 0 && MaxRequests > 0)
{
legacy.Add(new RateLimitRule
{
PerSeconds = PerSeconds,
MaxRequests = MaxRequests,
Name = "long"
});
}
if (AllowBurstForSeconds > 0 && AllowMaxBurstRequests > 0)
{
legacy.Add(new RateLimitRule
{
PerSeconds = AllowBurstForSeconds,
MaxRequests = AllowMaxBurstRequests,
Name = "burst"
});
}
return legacy;
}
}
// Similar updates for EnvironmentLimitsConfig, MicroserviceLimitsConfig, RouteLimitsConfig
```
**Configuration Example:**
```yaml
for_environment:
microservices:
concelier:
rules:
- per_seconds: 1
max_requests: 10
name: "per_second"
- per_seconds: 60

max_requests: 50000
name: "per_day"
```
**Testing:**
- Unit tests for rule array loading
- Backward compatibility with legacy config
- Validation of rule arrays
**Deliverable:** Configuration models support rule arrays.

### Task 3.2: Update Instance Limiter for Multiple Rules (1 day)
**Goal:** Evaluate all rules in InstanceRateLimiter.
**Files to Modify:**
1. `RateLimit/InstanceRateLimiter.cs` - Support multiple rules
**Implementation:**
```csharp
// InstanceRateLimiter.cs (UPDATED)
public sealed class InstanceRateLimiter : IDisposable
{
private readonly List<(RateLimitRule rule, SlidingWindowCounter counter)> _rules;
private readonly SlidingWindowCounter _activationCounter;
public InstanceRateLimiter(List<RateLimitRule> rules)
{
_rules = rules.Select(r => (r, new SlidingWindowCounter(r.PerSeconds))).ToList();

}
public RateLimitDecision TryAcquire(string? microservice)
{
_activationCounter.Increment();
if (_rules.Count == 0)
return RateLimitDecision.Allow(RateLimitScope.Instance, microservice, 0, 0);
var violations = new List<(RateLimitRule rule, ulong count, int retryAfter)>();
// Evaluate all rules
foreach (var (rule, counter) in _rules)
{
var count = (ulong)counter.Increment();
if (count > (ulong)rule.MaxRequests)
{
violations.Add((rule, count, rule.PerSeconds));
}
}
if (violations.Count > 0)
{
// Most restrictive retry-after wins (longest wait)
var maxRetryAfter = violations.Max(v => v.retryAfter);
var reason = DetermineReason(violations);
return RateLimitDecision.Deny(
RateLimitScope.Instance,
microservice,
reason,
maxRetryAfter,
violations[0].count,
0);
}
return RateLimitDecision.Allow(RateLimitScope.Instance, microservice, 0, 0);
}
private static RateLimitReason DetermineReason(List<(RateLimitRule rule, ulong count, int retryAfter)> violations)
{
// For multiple rule violations, use generic reason
return violations.Count == 1
? RateLimitReason.LongWindowExceeded
: RateLimitReason.LongAndBurstExceeded;
}
public long GetActivationCount() => _activationCounter.GetCount();
public void Dispose()
{
// Counters don't need disposal
}
}
```
**Testing:**
- Unit tests for multi-rule evaluation
- Verify all rules checked (AND logic)
- Most restrictive retry-after returned
- Single rule vs multiple rules
**Deliverable:** Instance limiter supports rule stacking.

**Goal:** Modify Lua script to handle array of rules in single call.
**Files to Modify:**
1. `RateLimit/Scripts/rate_limit_check.lua` - Multi-rule support
**Implementation:**
```lua
-- rate_limit_check_multi.lua (UPDATED)
-- KEYS: none
-- ARGV[1]: bucket prefix
-- ARGV[2]: service name (with route suffix if applicable)
-- ARGV[3]: JSON array of rules: [{"window_sec":1,"limit":10,"name":"per_second"}, ...]
-- Returns: {allowed (0/1), violations_json, max_retry_after}
local bucket = ARGV[1]
local svc = ARGV[2]
local rules_json = ARGV[3]
-- Parse rules
local rules = cjson.decode(rules_json)
local now = tonumber(redis.call("TIME")[1])
local violations = {}
local max_retry = 0
-- Evaluate each rule
for i, rule in ipairs(rules) do
local window_sec = tonumber(rule.window_sec)
local limit = tonumber(rule.limit)
local rule_name = rule.name or tostring(i)
-- Fixed window start
local window_start = now - (now % window_sec)
local key = bucket .. ":env:" .. svc .. ":" .. rule_name .. ":" .. window_start
-- Increment counter
local count = redis.call("INCR", key)
if count == 1 then
redis.call("EXPIRE", key, window_sec + 2)
end
-- Check limit
if count > limit then
local retry = (window_start + window_sec) - now
table.insert(violations, {
rule = rule_name,
count = count,
limit = limit,
retry_after = retry
})
if retry > max_retry then
max_retry = retry
end
end
end
-- Result
local allowed = (#violations == 0) and 1 or 0
local violations_json = cjson.encode(violations)
return {allowed, violations_json, max_retry}
```
**Files to Modify:**
2. `RateLimit/ValkeyRateLimitStore.cs` - Update to use new script
**Implementation:**
```csharp
// ValkeyRateLimitStore.cs (UPDATED)
public async Task<RateLimitDecision> CheckLimitAsync(
string serviceKey,

limit = r.MaxRequests,
name = r.Name ?? "rule"
}));
var values = new RedisValue[]
{
_bucket,
serviceKey,
rulesJson
};
var result = await _db.ScriptEvaluateAsync(
_rateLimitScriptSha,
Array.Empty<RedisKey>(),
values);
var array = (RedisResult[])result;
var allowed = (int)array[0] == 1;
var violationsJson = (string)array[1];
var maxRetryAfter = (int)array[2];
if (allowed)
{
return RateLimitDecision.Allow(RateLimitScope.Environment, serviceKey, 0, 0);
}
// Parse violations for reason
var violations = JsonSerializer.Deserialize<List<RuleViolation>>(violationsJson);
var reason = violations!.Count == 1
? RateLimitReason.LongWindowExceeded
: RateLimitReason.LongAndBurstExceeded;
return RateLimitDecision.Deny(
RateLimitScope.Environment,
serviceKey,
reason,
maxRetryAfter,
(ulong)violations[0].Count,
0);
}
private sealed class RuleViolation
{
[JsonPropertyName("rule")]
public string Rule { get; set; } = "";
[JsonPropertyName("count")]
public int Count { get; set; }
[JsonPropertyName("limit")]
public int Limit { get; set; }
[JsonPropertyName("retry_after")]
public int RetryAfter { get; set; }
}
```
**Testing:**
- Integration tests with Testcontainers (Valkey)
- Multiple rules in single Lua call
- Verify atomicity
- Verify retry-after calculation
**Deliverable:** Valkey backend supports rule stacking.

var rules = new List<RateLimitRule>();
// Layer 1: Global environment defaults
if (_config.ForEnvironment != null)
{
rules.AddRange(_config.ForEnvironment.GetEffectiveRules());
}
// Layer 2: Microservice overrides (REPLACES global)
if (_config.ForEnvironment?.Microservices.TryGetValue(microservice, out var msConfig) == true)
{
var msRules = msConfig.GetEffectiveRules();
if (msRules.Count > 0)
{
rules = msRules; // Replace, not merge
}
// Layer 3: Route overrides (REPLACES microservice)
if (!string.IsNullOrWhiteSpace(routeName) &&
msConfig.Routes.TryGetValue(routeName, out var routeConfig))
{
var routeRules = routeConfig.GetEffectiveRules();
if (routeRules.Count > 0)
{
rules = routeRules; // Replace, not merge
}
}

# Router Rate Limiting - Implementation Guide
**For:** Implementation agents executing Sprint 1200_001_001 through 1200_001_006
**Last Updated:** 2025-12-17
---
## Purpose
This guide provides comprehensive technical context for implementing centralized rate limiting in Stella Router. It covers architecture decisions, patterns, gotchas, and operational considerations.
---
## Table of Contents
1. [Architecture Overview](#architecture-overview)
2. [Configuration Philosophy](#configuration-philosophy)
3. [Performance Considerations](#performance-considerations)
4. [Valkey Integration](#valkey-integration)
5. [Testing Strategy](#testing-strategy)
6. [Common Pitfalls](#common-pitfalls)
7. [Debugging Guide](#debugging-guide)
8. [Operational Runbook](#operational-runbook)
---
## Architecture Overview
### Design Principles
1. **Router-Centralized**: Rate limiting is a router responsibility, not a microservice responsibility
2. **Fail-Open**: Never block all traffic due to infrastructure failures
3. **Observable**: Every decision must be metrified
4. **Deterministic**: Same request at same time should get same decision (within window)
5. **Fair**: Use sliding windows where possible to avoid thundering herd
### Two-Tier Architecture
```
Request → Instance Limiter (in-memory, <1ms) → Environment Limiter (Valkey, <10ms) → Upstream
↓ DENY ↓ DENY
429 + Retry-After 429 + Retry-After
```
**Why two tiers?**
- **Instance tier** protects individual router process (CPU, memory, sockets)
- **Environment tier** protects shared backend (aggregate across all routers)
Both are necessary—single router can be overwhelmed locally even if aggregate traffic is low.
### Decision Flow
```
1. Extract microservice + route from request
2. Check instance limits (always, fast path)
└─> DENY? Return 429
3. Check activation gate (local 5-min counter)
└─> Below threshold? Skip env check (optimization)
4. Check environment limits (Valkey call)
└─> Circuit breaker open? Skip (fail-open)
└─> Valkey error? Skip (fail-open)
└─> DENY? Return 429
5. Forward to upstream
```
---
## Configuration Philosophy
### Inheritance Model
```
Global Defaults
└─> Environment Defaults
└─> Microservice Overrides
└─> Route Overrides (most specific)
```
**Replacement, not merge**: When a child level specifies limits, it REPLACES parent limits entirely.
**Example:**
```yaml
for_environment:
per_seconds: 300
max_requests: 30000 # Global default
microservices:
scanner:
per_seconds: 60
max_requests: 600 # REPLACES global (not merged)
routes:
scan_submit:
per_seconds: 10
max_requests: 50 # REPLACES microservice (not merged)
```
Result:
- `POST /scanner/api/scans` → 50 req/10sec (route level)
- `GET /scanner/api/other` → 600 req/60sec (microservice level)
- `GET /policy/api/evaluate` → 30000 req/300sec (global level)
### Rule Stacking (AND Logic)
Multiple rules at same level = ALL must pass.
```yaml
concelier:
rules:
- per_seconds: 1
max_requests: 10 # Rule 1: 10/sec
- per_seconds: 3600
max_requests: 3000 # Rule 2: 3000/hour
```
Both rules enforced. Request denied if EITHER limit exceeded.
### Sensible Defaults
If configuration omitted:
- `for_instance`: No limits (effectively unlimited)
- `for_environment`: No limits
- `activation_threshold`: 5000 (skip Valkey if <5000 req/5min)
- `circuit_breaker.failure_threshold`: 5
- `circuit_breaker.timeout_seconds`: 30
**Recommendation**: Always configure at least global defaults.
---
## Performance Considerations
### Instance Limiter Performance
**Target:** <1ms P99 latency
**Implementation:** Sliding window with ring buffer.
```csharp
// Efficient: O(1) increment, O(k) advance where k = buckets cleared
long[] _buckets; // Ring buffer, size = window_seconds / granularity
long _total; // Running sum
```
**Lock contention**: Single lock per counter. Acceptable for <10k req/sec per router.
**Memory**: ~24 bytes per window (array overhead + fields).
**Optimization**: For very high traffic (>50k req/sec), consider lock-free implementation with `Interlocked` operations.
### Environment Limiter Performance
**Target:** <10ms P99 latency (including Valkey RTT)
**Critical path**: Every request to environment limiter makes a Valkey call.
**Optimization: Activation Gate**
Skip Valkey if local instance traffic < threshold:
```csharp
if (_instanceCounter.GetCount() < _config.ActivationThresholdPer5Min)
{
// Skip expensive Valkey check
return instanceDecision;
}
```
**Effect**: Reduces Valkey load by 80%+ in low-traffic scenarios.
**Trade-off**: Under threshold, environment limits not enforced. Acceptable if:
- Each router instance threshold is set appropriately
- Primary concern is high-traffic scenarios
**Lua Script Performance**
- Single round-trip to Valkey (atomic)
- Multiple `INCR` operations in single script (fast, no network)
- TTL set only on first increment (optimization)
**Valkey Sizing**: 1000 ops/sec per router instance = 10k ops/sec for 10 routers. Valkey handles this easily (100k+ ops/sec capacity).
---
## Valkey Integration
### Connection Management
Use `ConnectionMultiplexer` from StackExchange.Redis:
```csharp
var _connection = ConnectionMultiplexer.Connect(connectionString);
var _db = _connection.GetDatabase();
```
**Important**: ConnectionMultiplexer is thread-safe and expensive to create. Create ONCE per application, reuse everywhere.
### Lua Script Loading
Scripts loaded at startup and cached by SHA:
```csharp
var script = File.ReadAllText("rate_limit_check.lua");
var server = _connection.GetServer(_connection.GetEndPoints().First());
var sha = server.ScriptLoad(script);
```
**Persistence**: Valkey caches scripts in memory. They survive across requests but NOT across restarts.
**Recommendation**: Load script at startup, store SHA, use `ScriptEvaluateAsync(sha, ...)` for all calls.
### Key Naming Strategy
Format: `{bucket}:env:{service}:{rule_name}:{window_start}`
Example: `stella-router-rate-limit:env:concelier:per_second:1702821600`
**Why include window_start in key?**
Fixed windows—each window is a separate key with TTL. When window expires, key auto-deleted.
**Benefit**: No manual cleanup, memory efficient.
### Clock Skew Handling
**Problem**: Different routers may have slightly different clocks, causing them to disagree on window boundaries.
**Solution**: Use Valkey server time (`redis.call("TIME")`) in Lua script, not client time.
```lua
local now = tonumber(redis.call("TIME")[1]) -- Valkey server time
local window_start = now - (now % window_sec)
```
**Result**: All routers agree on window boundaries (Valkey is source of truth).
### Circuit Breaker Thresholds
**failure_threshold**: 5 consecutive failures before opening
**timeout_seconds**: 30 seconds before attempting half-open
**half_open_timeout**: 10 seconds to test one request
**Tuning**:
- Lower failure_threshold = faster fail-open (more availability, less strict limiting)
- Higher failure_threshold = tolerate more transient errors (stricter limiting)
**Recommendation**: Start with defaults, adjust based on Valkey stability.
---
## Testing Strategy
### Unit Tests (xUnit)
**Coverage targets:**
- Configuration loading: 100%
- Validation logic: 100%
- Sliding window counter: 100%
- Route matching: 100%
- Inheritance resolution: 100%
**Test patterns:**
```csharp
[Fact]
public void SlidingWindowCounter_WhenWindowExpires_ResetsCount()
{
var counter = new SlidingWindowCounter(windowSeconds: 10);
counter.Increment(); // count = 1
// Simulate time passing (mock or Thread.Sleep in tests)
AdvanceTime(11); // seconds
Assert.Equal(0, counter.GetCount()); // Window expired, count reset
}
```
### Integration Tests (TestServer + Testcontainers)
**Valkey integration:**
```csharp
[Fact]
public async Task EnvironmentLimiter_WhenLimitExceeded_Returns429()
{
using var valkey = new ValkeyContainer();
await valkey.StartAsync();
var store = new ValkeyRateLimitStore(valkey.GetConnectionString(), "test-bucket");
var limiter = new EnvironmentRateLimiter(store, circuitBreaker, logger);
var limits = new EffectiveLimits(perSeconds: 1, maxRequests: 5, ...);
// First 5 requests should pass
for (int i = 0; i < 5; i++)
{
var decision = await limiter.TryAcquireAsync("test-svc", limits, CancellationToken.None);
Assert.True(decision.Value.Allowed);
}
// 6th request should be denied
var deniedDecision = await limiter.TryAcquireAsync("test-svc", limits, CancellationToken.None);
Assert.False(deniedDecision.Value.Allowed);
Assert.Equal(429, deniedDecision.Value.RetryAfterSeconds);
}
```
**Middleware integration:**
```csharp
[Fact]
public async Task RateLimitMiddleware_WhenLimitExceeded_Returns429WithRetryAfter()
{
using var testServer = new TestServer(new WebHostBuilder().UseStartup<Startup>());
var client = testServer.CreateClient();
// Configure rate limit: 5 req/sec
// Send 6 requests rapidly
for (int i = 0; i < 6; i++)
{
var response = await client.GetAsync("/api/test");
if (i < 5)
{
Assert.Equal(HttpStatusCode.OK, response.StatusCode);
}
else
{
Assert.Equal(HttpStatusCode.TooManyRequests, response.StatusCode);
Assert.True(response.Headers.Contains("Retry-After"));
}
}
}
```
### Load Tests (k6)
**Scenario A: Instance Limits**
```javascript
import http from 'k6/http';
import { check } from 'k6';
export const options = {
scenarios: {
instance_limit: {
executor: 'constant-arrival-rate',
rate: 100, // 100 req/sec
timeUnit: '1s',
duration: '30s',
preAllocatedVUs: 50,
},
},
};
export default function () {
const res = http.get('http://router/api/test');
check(res, {
'status 200 or 429': (r) => r.status === 200 || r.status === 429,
'has Retry-After on 429': (r) => r.status !== 429 || r.headers['Retry-After'] !== undefined,
});
}
```
**Scenario B: Environment Limits (Multi-Instance)**
Run k6 from 5 different machines simultaneously → simulate 5 router instances → verify aggregate limit enforced.
**Scenario E: Valkey Failure**
Use Toxiproxy to inject network failures → verify circuit breaker opens → verify requests still allowed (fail-open).
---
## Common Pitfalls
### 1. Forgetting to Update Middleware Pipeline Order
**Problem**: Rate limit middleware added AFTER routing decision → can't identify microservice.
**Solution**: Add rate limit middleware BEFORE routing decision:
```csharp
app.UsePayloadLimits();
app.UseRateLimiting(); // HERE
app.UseEndpointResolution();
app.UseRoutingDecision();
```
### 2. Circuit Breaker Never Closes
**Problem**: Circuit breaker opens, but never attempts recovery.
**Cause**: Half-open logic not implemented or timeout too long.
**Solution**: Implement half-open state with timeout:
```csharp
if (_state == CircuitState.Open && DateTime.UtcNow >= _halfOpenAt)
{
_state = CircuitState.HalfOpen; // Allow one test request
}
```
### 3. Lua Script Not Found at Runtime
**Problem**: Script file not copied to output directory.
**Solution**: Set file properties in `.csproj`:
```xml
<ItemGroup>
<Content Include="RateLimit\Scripts\*.lua">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>
</ItemGroup>
```
### 4. Activation Gate Never Triggers
**Problem**: Activation counter not incremented on every request.
**Cause**: Counter incremented only when instance limit is enforced.
**Solution**: Increment activation counter ALWAYS, not just when checking limits:
```csharp
public RateLimitDecision TryAcquire(string? microservice)
{
_activationCounter.Increment(); // ALWAYS increment
// ... rest of logic
}
```
### 5. Route Matching Case-Sensitivity Issues
**Problem**: `/API/Scans` doesn't match `/api/scans`.
**Solution**: Use case-insensitive comparisons:
```csharp
string.Equals(requestPath, pattern, StringComparison.OrdinalIgnoreCase)
```
### 6. Valkey Key Explosion
**Problem**: Too many keys in Valkey, memory usage high.
**Cause**: Forgetting to set TTL on keys.
**Solution**: ALWAYS set TTL when creating keys:
```lua
if count == 1 then
redis.call("EXPIRE", key, window_sec + 2)
end
```
**+2 buffer**: Gives grace period to avoid edge cases.
---
## Debugging Guide
### Scenario 1: Requests Being Denied But Shouldn't Be
**Steps:**
1. Check metrics: Which scope is denying? (instance or environment)
```promql
rate(stella_router_rate_limit_denied_total[1m])
```
2. Check configured limits:
```bash
# View config
kubectl get configmap router-config -o yaml | grep -A 20 "rate_limiting"
```
3. Check activation gate:
```promql
stella_router_rate_limit_activation_gate_enabled
```
If 0, activation gate is disabled—all requests hit Valkey.
4. Check Valkey keys:
```bash
redis-cli -h valkey.stellaops.local
> KEYS stella-router-rate-limit:env:*
> TTL stella-router-rate-limit:env:concelier:per_second:1702821600
> GET stella-router-rate-limit:env:concelier:per_second:1702821600
```
5. Check circuit breaker state:
```promql
stella_router_rate_limit_circuit_breaker_state{state="open"}
```
If 1, circuit breaker is open—env limits not enforced.
### Scenario 2: Rate Limits Not Being Enforced
**Steps:**
1. Verify middleware is registered:
```csharp
// Check Startup.cs or Program.cs
app.UseRateLimiting(); // Should be present
```
2. Verify configuration loaded:
```csharp
// Add logging in RateLimitService constructor
_logger.LogInformation("Rate limit config loaded: Instance={HasInstance}, Env={HasEnv}",
_config.ForInstance != null,
_config.ForEnvironment != null);
```
3. Check metrics—are requests even hitting rate limiter?
```promql
rate(stella_router_rate_limit_allowed_total[1m])
```
If 0, middleware not in pipeline or not being called.
4. Check microservice identification:
```csharp
// Add logging in middleware
var microservice = context.Items["RoutingTarget"] as string;
_logger.LogDebug("Rate limiting request for microservice: {Microservice}", microservice);
```
If "unknown", routing metadata not set—rate limiter can't apply service-specific limits.
### Scenario 3: Valkey Errors
**Steps:**
1. Check circuit breaker metrics:
```promql
rate(stella_router_rate_limit_valkey_call_total{result="error"}[5m])
```
2. Check Valkey connectivity:
```bash
redis-cli -h valkey.stellaops.local PING
```
3. Check Lua script loaded:
```bash
redis-cli -h valkey.stellaops.local SCRIPT EXISTS <sha>
```
4. Check Valkey logs for errors:
```bash
kubectl logs -f valkey-0 | grep ERROR
```
5. Verify Lua script syntax:
```bash
redis-cli -h valkey.stellaops.local --eval rate_limit_check.lua
```
---
## Operational Runbook
### Deployment Checklist
- [ ] Valkey cluster healthy (check `redis-cli PING`)
- [ ] Configuration validated (run `stella-router validate-config`)
- [ ] Metrics scraping configured (Prometheus targets)
- [ ] Dashboards imported (Grafana)
- [ ] Alerts configured (Alertmanager)
- [ ] Shadow mode enabled (limits set 10x expected traffic)
- [ ] Rollback plan documented
### Monitoring Dashboards
**Dashboard 1: Rate Limiting Overview**
Panels:
- Requests allowed vs denied (pie chart)
- Denial rate by microservice (line graph)
- Denial rate by route (heatmap)
- Retry-After distribution (histogram)
**Dashboard 2: Performance**
Panels:
- Decision latency P50/P95/P99 (instance vs environment)
- Valkey call latency P95
- Activation gate effectiveness (% skipped)
**Dashboard 3: Health**
Panels:
- Circuit breaker state (gauge)
- Valkey error rate
- Most denied routes (top 10 table)
### Alert Definitions
**Critical:**
```yaml
- alert: RateLimitValkeyCriticalFailure
expr: stella_router_rate_limit_circuit_breaker_state{state="open"} == 1
for: 5m
annotations:
summary: "Rate limit circuit breaker open for >5min"
description: "Valkey unavailable, environment limits not enforced"
- alert: RateLimitAllRequestsDenied
expr: rate(stella_router_rate_limit_denied_total[1m]) / rate(stella_router_rate_limit_allowed_total[1m]) > 0.99
for: 1m
annotations:
summary: "100% denial rate"
description: "Possible configuration error"
```
**Warning:**
```yaml
- alert: RateLimitHighDenialRate
expr: rate(stella_router_rate_limit_denied_total[5m]) / (rate(stella_router_rate_limit_allowed_total[5m]) + rate(stella_router_rate_limit_denied_total[5m])) > 0.2
for: 5m
annotations:
summary: ">20% requests denied"
description: "High denial rate, check if expected"
- alert: RateLimitValkeyHighLatency
expr: histogram_quantile(0.95, stella_router_rate_limit_decision_latency_ms{scope="environment"}) > 100
for: 5m
annotations:
summary: "Valkey latency >100ms P95"
description: "Valkey performance degraded"
```
### Tuning Guidelines
**Scenario: Too many requests denied**
1. Check if denial rate is expected (traffic spike?)
2. If not, increase limits:
- Start with 2x current limits
- Monitor for 24 hours
- Adjust as needed
**Scenario: Valkey overloaded**
1. Check ops/sec: `redis-cli INFO stats | grep instantaneous_ops_per_sec`
2. If >50k ops/sec, consider:
- Increase activation threshold (reduce Valkey calls)
- Add Valkey replicas (read scaling)
- Shard by microservice (write scaling)
**Scenario: Circuit breaker flapping**
1. Check failure rate:
```promql
rate(stella_router_rate_limit_valkey_call_total{result="error"}[5m])
```
2. If transient errors, increase failure_threshold
3. If persistent errors, fix Valkey issue
### Rollback Procedure
1. Disable rate limiting:
```yaml
rate_limiting:
for_instance: null
for_environment: null
```
2. Deploy config update
3. Verify traffic flows normally
4. Investigate issue offline

## Quick Start for Agents
### 1. Context Gathering (30 minutes)
**Read in this order:**
1. `SPRINT_1200_001_000_router_rate_limiting_master.md` - Overview
2. `SPRINT_1200_001_IMPLEMENTATION_GUIDE.md` - Technical details
3. Original advisory: `docs/product-advisories/unprocessed/15-Dec-2025 - Designing 202 + Retry‑After Backpressure Control.md`
4. Analysis plan: `C:\Users\VladimirMoushkov\.claude\plans\vectorized-kindling-rocket.md`
### 2. Environment Setup
```bash
# Working directory
cd src/__Libraries/StellaOps.Router.Gateway/
# Verify dependencies
dotnet restore
# Install Valkey for local testing
docker run -d -p 6379:6379 valkey/valkey:latest
# Run existing tests to ensure baseline
dotnet test
```
### 3. Start Sprint 1
Open `SPRINT_1200_001_001_router_rate_limiting_core.md` and follow task breakdown.
**Task execution pattern:**
```
For each task:
1. Read task description
2. Review implementation code samples
3. Create files as specified
4. Write unit tests
5. Mark task complete in master tracker
6. Commit with message: "feat(router): [Sprint 1.X] Task name"
```
---
## Key Design Decisions (Reference)
### 1. Status Codes
- ✅ **429 Too Many Requests** for rate limiting
- ❌ NOT 503 (that's for service health)
- ❌ NOT 202 (that's for async job acceptance)
### 2. Two-Scope Architecture
- **for_instance**: In-memory, protects single router
- **for_environment**: Valkey-backed, protects aggregate
Both are necessary—can't replace one with the other.
### 3. Fail-Open Philosophy
- Circuit breaker on Valkey failures
- Activation gate optimization
- Instance limits enforced even if Valkey down
### 4. Configuration Inheritance
- Replacement semantics (not merge)
- Most specific wins: route > microservice > environment > global
### 5. Rule Stacking
- Multiple rules per target = AND logic
- All rules must pass
- Most restrictive Retry-After returned

## Common Implementation Gotchas
⚠️ **Middleware Pipeline Order**
```csharp
// CORRECT:
app.UsePayloadLimits();
app.UseRateLimiting(); // BEFORE routing
app.UseEndpointResolution();
// WRONG:
app.UseEndpointResolution();
app.UseRateLimiting(); // Too late, can't identify microservice
```
⚠️ **Lua Script Deployment**
```xml
<!-- REQUIRED in .csproj -->
<ItemGroup>
<Content Include="RateLimit\Scripts\*.lua">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>
</ItemGroup>
```
⚠️ **Clock Skew**
```lua
-- CORRECT: Use Valkey server time
local now = tonumber(redis.call("TIME")[1])
-- WRONG: Use client time (clock skew issues)
local now = os.time()
```
⚠️ **Circuit Breaker Half-Open**
```csharp
// REQUIRED: Implement half-open state
if (_state == CircuitState.Open && DateTime.UtcNow >= _halfOpenAt)
{
_state = CircuitState.HalfOpen; // Allow ONE test request
}
```

## Configuration Quick Reference
### Minimal Config (Just Defaults)
```yaml
rate_limiting:
for_instance:
per_seconds: 300
max_requests: 30000
```
### Full Config (All Features)

# Sprint 3401.0002.0001 · Score Replay & Proof Bundle
## Topic & Scope
Implement the score replay capability and proof bundle writer from the "Building a Deeper Moat Beyond Reachability" advisory. This sprint delivers:
1. **Score Proof Ledger** - Append-only ledger tracking each scoring decision with per-node hashing
2. **Proof Bundle Writer** - Content-addressed ZIP bundle with manifests and proofs
3. **Score Replay Endpoint** - `POST /score/replay` to recompute scores without rescanning
4. **Scan Manifest** - DSSE-signed manifest capturing all inputs affecting results
**Source Advisory**: `docs/product-advisories/unprocessed/16-Dec-2025 - Building a Deeper Moat Beyond Reachability.md`
**Related Docs**: `docs/product-advisories/14-Dec-2025 - Determinism and Reproducibility Technical Reference.md` §11.2, §12
**Working Directory**: `src/Scanner/StellaOps.Scanner.WebService`, `src/Policy/__Libraries/StellaOps.Policy/`
## Dependencies & Concurrency
- **Depends on**: SPRINT_3401_0001_0001 (Determinism Scoring Foundations) - DONE
- **Depends on**: SPRINT_0501_0004_0001 (Proof Spine Assembly) - Partial (PROOF-SPINE-0009 blocked)
- **Blocking**: Ground-truth corpus CI gates need this for replay validation
- **Safe to parallelize with**: Unknowns ranking implementation
## Documentation Prerequisites
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/scanner/architecture.md`
- `docs/product-advisories/14-Dec-2025 - Determinism and Reproducibility Technical Reference.md`
- `docs/benchmarks/ground-truth-corpus.md` (new)

## Technical Specifications
### Scan Manifest
```csharp
public sealed record ScanManifest(
string ScanId,
DateTimeOffset CreatedAtUtc,
string ArtifactDigest, // sha256:... or image digest
string ArtifactPurl, // optional
string ScannerVersion, // scanner.webservice version
string WorkerVersion, // scanner.worker.* version
string ConcelierSnapshotHash, // immutable feed snapshot digest
string ExcititorSnapshotHash, // immutable vex snapshot digest
string LatticePolicyHash, // policy bundle digest
bool Deterministic,
byte[] Seed, // 32 bytes
IReadOnlyDictionary<string,string> Knobs // depth limits etc.
);
```
### Proof Bundle Contents
```
bundle.zip/
├── manifest.json # Canonical JSON scan manifest
├── manifest.dsse.json # DSSE envelope for manifest
├── score_proof.json # ProofLedger nodes array (v1 JSON, swap to CBOR later)
├── proof_root.dsse.json # DSSE envelope for root hash
└── meta.json # { rootHash, createdAtUtc }
```
### Score Replay Contract
```
POST /scan/{scanId}/score/replay
Response:
{
"score": 0.73,
"rootHash": "sha256:abc123...",
"bundleUri": "/var/lib/stellaops/proofs/scanId_abc123.zip"
}
```
Invariant: Same manifest + same seed + same frozen clock = identical rootHash.

---
## Decisions & Risks
- **Risk**: Proof bundle storage could grow large for high-volume scanning. Mitigation: Add retention policy and cleanup job in follow-up sprint.
- **Decision**: Use JSON for v1 proof ledger encoding; migrate to CBOR in v2 for compactness.
- **Dependency**: Signer integration assumes SPRINT_0501_0008_0001 key rotation is available.
---
## Next Checkpoints
- [ ] Schema review with DB team before Task 7/9
- [ ] API review with scanner team before Task 10

### EPSS-3410-003: Implement IEpssSource Interface
**Description**: Define abstraction for fetching EPSS CSV data.
**File**: `src/Concelier/__Libraries/StellaOps.Concelier.Epss/Sources/IEpssSource.cs`
**Implementation**:
```csharp
namespace StellaOps.Concelier.Epss.Sources;
/// <summary>
/// Source for EPSS CSV data (online or bundle).
/// </summary>
public interface IEpssSource
{
/// <summary>
/// Fetches EPSS CSV for the specified model date.
/// Returns a stream of the compressed (.gz) or decompressed CSV data.
/// </summary>
/// <param name="modelDate">Date for which EPSS scores are requested</param>
/// <param name="cancellationToken">Cancellation token</param>
/// <returns>Stream of CSV data (may be GZip compressed)</returns>
Task<EpssSourceResult> FetchAsync(DateOnly modelDate, CancellationToken cancellationToken);
}
/// <summary>
/// Result from EPSS source fetch operation.
/// </summary>
public sealed record EpssSourceResult
{
public required Stream DataStream { get; init; }
public required string SourceUri { get; init; }
public required bool IsCompressed { get; init; }
public required long SizeBytes { get; init; }
public string? ETag { get; init; }
public DateTimeOffset? LastModified { get; init; }
}
```
**Acceptance Criteria**:
- [ ] Interface defines `FetchAsync` method
- [ ] Result includes stream, URI, compression flag
- [ ] Supports both online and bundle sources via DI
---
### EPSS-3410-006: Implement EpssCsvStreamParser
**Description**: Parse EPSS CSV stream with comment line extraction and validation.
**File**: `src/Concelier/__Libraries/StellaOps.Concelier.Epss/Parsing/EpssCsvStreamParser.cs`
**Key Requirements**:
- Handle leading `# model: v2025.03.14, published: 2025-03-14` comment line
- Parse CSV header: `cve,epss,percentile`
- Stream processing (IAsyncEnumerable) for low memory footprint
- Validate each row (score/percentile bounds, CVE format)
- Report errors with line numbers
**Acceptance Criteria**:
- [ ] Extracts model version and published date from comment line
- [ ] Parses CSV rows into `EpssScoreRow`
- [ ] Validates bounds and CVE format
- [ ] Handles malformed rows gracefully (log warning, skip row)
- [ ] Streams results (IAsyncEnumerable<EpssScoreRow>)
- [ ] Unit tests cover: valid CSV, missing comment, invalid scores, malformed rows
---
### EPSS-3410-007: Implement EpssRepository
**Description**: Data access layer for EPSS tables.
**File**: `src/Concelier/__Libraries/StellaOps.Concelier.Storage.Postgres/Repositories/EpssRepository.cs`
**Methods**:
```csharp
public interface IEpssRepository
{
// Provenance
Task<Guid> CreateImportRunAsync(EpssImportRun importRun, CancellationToken ct);
Task UpdateImportRunStatusAsync(Guid importRunId, string status, string? error, CancellationToken ct);
// Bulk insert (uses NpgsqlBinaryImporter for performance)
Task<int> BulkInsertScoresAsync(Guid importRunId, IAsyncEnumerable<EpssScoreRow> rows, CancellationToken ct);
// Delta computation
Task<int> ComputeChangesAsync(DateOnly modelDate, Guid importRunId, EpssThresholds thresholds, CancellationToken ct);
// Current projection
Task<int> UpsertCurrentAsync(DateOnly modelDate, CancellationToken ct);
// Queries
Task<DateOnly?> GetLatestModelDateAsync(CancellationToken ct);
Task<EpssImportRun?> GetImportRunAsync(DateOnly modelDate, CancellationToken ct);
}
```
**Performance Requirements**:
- `BulkInsertScoresAsync`: >10k rows/second (use NpgsqlBinaryImporter)
- `ComputeChangesAsync`: <30s for 300k rows
- `UpsertCurrentAsync`: <15s for 300k rows
**Acceptance Criteria**:
- [ ] All methods implemented with Dapper + Npgsql
- [ ] `BulkInsertScoresAsync` uses `NpgsqlBinaryImporter` (not parameterized inserts)
- [ ] Transaction safety (rollback on failure)
- [ ] Integration tests with Testcontainers verify correctness and performance

### EPSS-3410-008: Implement EpssChangeDetector
**Description**: Compute delta and assign flags for enrichment targeting.
**File**: `src/Concelier/__Libraries/StellaOps.Concelier.Epss/Logic/EpssChangeDetector.cs`
**Flag Logic**:
```csharp
[Flags]
public enum EpssChangeFlags
{
None = 0,
NewScored = 1, // CVE appeared in EPSS for first time
CrossedHigh = 2, // Percentile crossed HighPercentile (default 95th)
BigJump = 4, // |delta_score| >= BigJumpDelta (default 0.10)
DroppedLow = 8, // Percentile dropped below LowPercentile (default 50th)
ScoreIncreased = 16, // Any positive delta
ScoreDecreased = 32 // Any negative delta
}
public sealed record EpssThresholds
{
public double HighPercentile { get; init; } = 0.95;
public double LowPercentile { get; init; } = 0.50;
public double BigJumpDelta { get; init; } = 0.10;
}
```
**SQL Implementation** (called by `ComputeChangesAsync`):
```sql
INSERT INTO concelier.epss_changes (model_date, cve_id, old_score, old_percentile, new_score, new_percentile, delta_score, delta_percentile, flags)
SELECT
@model_date AS model_date,
COALESCE(new.cve_id, old.cve_id) AS cve_id,
old.epss_score AS old_score,
old.percentile AS old_percentile,
new.epss_score AS new_score,
new.percentile AS new_percentile,
CASE WHEN old.epss_score IS NOT NULL THEN new.epss_score - old.epss_score ELSE NULL END AS delta_score,
CASE WHEN old.percentile IS NOT NULL THEN new.percentile - old.percentile ELSE NULL END AS delta_percentile,
(
CASE WHEN old.cve_id IS NULL THEN 1 ELSE 0 END | -- NEW_SCORED
CASE WHEN old.percentile < @high_percentile AND new.percentile >= @high_percentile THEN 2 ELSE 0 END | -- CROSSED_HIGH
CASE WHEN ABS(COALESCE(new.epss_score - old.epss_score, 0)) >= @big_jump_delta THEN 4 ELSE 0 END | -- BIG_JUMP
CASE WHEN old.percentile >= @low_percentile AND new.percentile < @low_percentile THEN 8 ELSE 0 END | -- DROPPED_LOW
CASE WHEN old.epss_score IS NOT NULL AND new.epss_score > old.epss_score THEN 16 ELSE 0 END | -- SCORE_INCREASED
CASE WHEN old.epss_score IS NOT NULL AND new.epss_score < old.epss_score THEN 32 ELSE 0 END -- SCORE_DECREASED
) AS flags
FROM concelier.epss_scores new
LEFT JOIN concelier.epss_current old ON new.cve_id = old.cve_id
WHERE new.model_date = @model_date
AND (
old.cve_id IS NULL OR -- New CVE
ABS(new.epss_score - old.epss_score) >= 0.001 OR -- Score changed
ABS(new.percentile - old.percentile) >= 0.001 -- Percentile changed
);
```
**Acceptance Criteria**:
- [ ] Flags computed correctly per logic above
- [ ] Unit tests cover all flag combinations
- [ ] Edge cases: first-ever ingest (all NEW_SCORED), no changes (empty result)
---

```csharp
public sealed class EpssIngestJob : IJob
{
public async Task<JobResult> ExecuteAsync(JobContext context, CancellationToken ct)
{
var args = context.Args.ToObject<EpssIngestArgs>();
var modelDate = args.Date ?? DateOnly.FromDateTime(DateTime.UtcNow.AddDays(-1));
// 1. Create import run (provenance)
var importRun = new EpssImportRun { ModelDate = modelDate, Status = "IN_PROGRESS" };
var importRunId = await _epssRepository.CreateImportRunAsync(importRun, ct);
try
{
// 2. Fetch CSV (online or bundle)
var source = args.Source == "online" ? _onlineSource : _bundleSource;
var fetchResult = await source.FetchAsync(modelDate, ct);
// 3. Parse CSV stream
var parser = new EpssCsvStreamParser(fetchResult.DataStream, modelDate);
var rows = parser.ParseAsync(ct);
// 4. Bulk insert into epss_scores
var rowCount = await _epssRepository.BulkInsertScoresAsync(importRunId, rows, ct);
// 5. Compute delta (epss_changes)
var changeCount = await _epssRepository.ComputeChangesAsync(modelDate, importRunId, _thresholds, ct);
// 6. Upsert epss_current
var currentCount = await _epssRepository.UpsertCurrentAsync(modelDate, ct);
// 7. Mark import success
await _epssRepository.UpdateImportRunStatusAsync(importRunId, "SUCCEEDED", null, ct);
// 8. Emit outbox event
await _outboxPublisher.EnqueueAsync(new EpssUpdatedEvent
{
ModelDate = modelDate,
ImportRunId = importRunId,
RowCount = rowCount,
ChangeCount = changeCount
}, ct);
return JobResult.Success($"Imported {rowCount} EPSS scores, {changeCount} changes");
}
catch (Exception ex)
{
await _epssRepository.UpdateImportRunStatusAsync(importRunId, "FAILED", ex.Message, ct);
throw;
}
}
}
```

---
## Rollout Plan
### Phase 1: Development
- [ ] Schema migration executed in dev environment
- [ ] Unit tests passing
- [ ] Integration tests passing
- [ ] Performance tests passing
### Phase 2: Staging
- [ ] Manual ingestion test (bundle import)
- [ ] Online ingestion test (FIRST.org live)
- [ ] Monitor logs/metrics for 3 days
- [ ] Verify: no P1 incidents, <1% error rate
### Phase 3: Production
- [ ] Enable scheduled ingestion (00:05 UTC)
- [ ] Alert on: staleness >7 days, ingest failures, delta anomalies
- [ ] Monitor for 1 week before Sprint 3411 (Scanner integration)
---
## Risks & Mitigations
| Risk | Likelihood | Impact | Mitigation |
|------|------------|--------|------------|
| **FIRST.org downtime during ingest** | LOW | MEDIUM | Exponential backoff (3 retries), alert on failure, air-gap fallback |
| **CSV schema change (FIRST adds columns)** | LOW | HIGH | Parser handles extra columns gracefully, comment line is optional |
| **Performance degradation (>300k rows)** | LOW | MEDIUM | Partitions + indexes, NpgsqlBinaryImporter, performance tests |
| **Partition not created for future month** | LOW | MEDIUM | Auto-create via `ensure_epss_partitions_exist`, daily cron check |
| **Duplicate ingestion (scheduler bug)** | LOW | LOW | Unique constraint on `model_date`, idempotent job design |
---
## Acceptance Criteria (Sprint Exit)
- [ ] All 16 tasks completed and reviewed
- [ ] Database schema migrated (verified in dev, staging, prod)
- [ ] Unit tests: >90% coverage, all passing
- [ ] Integration tests: all scenarios passing
- [ ] Performance test: 310k rows ingested in <120s
- [ ] Observability: metrics, logs, traces verified in staging
- [ ] Scheduled job runs successfully for 3 consecutive days in staging
- [ ] Documentation: runbook completed, reviewed by ops team
- [ ] Code review: approved by 2+ engineers
- [ ] Security review: no secrets in logs, RBAC verified
---
## Dependencies for Next Sprints
**Sprint 3411 (Scanner Integration)** depends on:
- `epss_current` table populated
- `IEpssProvider` abstraction available (extended in Sprint 3411)
**Sprint 3413 (Live Enrichment)** depends on:
- `epss_changes` table populated with flags
- `epss.updated` event emitted
---
## Documentation
### Operator Runbook

## Technical Specification
### EPSS-SCAN-002: EpssEvidence Record
```csharp
/// <summary>
/// Immutable EPSS evidence captured at scan time.
/// </summary>
public record EpssEvidence
{
/// <summary>EPSS probability score [0,1] at scan time.</summary>
public required double Score { get; init; }
/// <summary>EPSS percentile rank [0,1] at scan time.</summary>
public required double Percentile { get; init; }
/// <summary>EPSS model date used.</summary>
public required DateOnly ModelDate { get; init; }
/// <summary>Import run ID for provenance tracking.</summary>
public required Guid ImportRunId { get; init; }
}
```
### EPSS-SCAN-003/004: IEpssProvider Interface
```csharp
public interface IEpssProvider
{
/// <summary>
/// Get current EPSS scores for multiple CVEs in a single call.
/// </summary>
Task<IReadOnlyDictionary<string, EpssEvidence>> GetCurrentAsync(
IEnumerable<string> cveIds,
CancellationToken ct);
/// <summary>
/// Get EPSS history for a single CVE.
/// </summary>
Task<IReadOnlyList<EpssEvidence>> GetHistoryAsync(
string cveId,
int days,
CancellationToken ct);
}
```
### EPSS-SCAN-007: Scoring Configuration
Add to `PolicyScoringConfig`:
```yaml
scoring:
weights:
cvss: 0.25
epss: 0.25 # NEW
reachability: 0.25
freshness: 0.15
frequency: 0.10
epss:
high_threshold: 0.50
high_percentile: 0.95
```

## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-17 | Sprint created from advisory processing | Agent |
| 2025-12-17 | EPSS-SCAN-001: Created 008_epss_integration.sql in Scanner Storage | Agent |
| 2025-12-17 | EPSS-SCAN-012: Created docs/modules/scanner/epss-integration.md | Agent |
---
## Decisions & Risks
- **Decision**: EPSS tables are in Scanner schema for now. When Concelier EPSS sprint completes, consider migrating or federating.
- **Risk**: Partition management needs automated job. Documented in migration file.
---
## Next Checkpoints
- [ ] Review EPSS-SCAN-001 migration script
- [ ] Start EPSS-SCAN-002/003 implementation once Concelier ingestion available

# SPRINT_3500_0001_0001: Deeper Moat Beyond Reachability — Master Plan
**Epic Owner**: Architecture Guild
**Product Owner**: Product Management
**Tech Lead**: Scanner Team Lead
**Sprint Duration**: 10 sprints (20 weeks)
**Start Date**: TBD
**Priority**: HIGH (Competitive Differentiation)
---
## Executive Summary
This master sprint implements two major evidence upgrades that establish StellaOps' competitive moat:
1. **Deterministic Score Proofs + Unknowns Registry** (Epic A)
2. **Binary Reachability v1 (.NET + Java)** (Epic B)
These features address gaps no competitor has filled per `docs/market/competitive-landscape.md`:
- No vendor offers deterministic replay with frozen feeds
- None sign reachability graphs with DSSE + Rekor
- Lattice VEX + explainable paths is unmatched
- Unknowns ranking is unique to StellaOps
**Business Value**: Enables sales differentiation on provability, auditability, and sovereign crypto support.

## Analysis Summary
### Positives for Applicability (7.5/10 Overall)
| Aspect | Score | Assessment |
|--------|-------|------------|
| Architectural fit | 9/10 | Excellent alignment; respects Scanner/Concelier/Excititor boundaries |
| Competitive value | 9/10 | Addresses proven gaps; moats are real and defensible |
| Implementation depth | 8/10 | Production-ready .NET code, schemas, APIs included |
| Phasing realism | 7/10 | Good sprint breakdown; .NET-only scope requires expansion |
| Unknowns complexity | 5/10 | Ranking formula needs simplification (defer centrality) |
| Integration completeness | 6/10 | Missing Smart-Diff tie-in, incomplete air-gap story |
| Postgres design | 6/10 | Schema isolation unclear, indexes incomplete |
| Rekor scalability | 7/10 | Hybrid attestations correct; needs budget policy |
### Key Strengths
1. **Respects architectural boundaries**: Scanner.WebService owns lattice/scoring; Concelier/Excititor preserve prune sources
2. **Builds on existing infrastructure**: ProofSpine (Attestor), deterministic scoring (Policy), reachability gates (Scanner)
3. **Complete implementation artifacts**: Canonical JSON, DSSE signing, EF Core entities, xUnit tests
4. **Pragmatic phasing**: Avoids "boil the ocean" with realistic sprint breakdown
### Key Weaknesses
1. **Language scope**: .NET-only reachability; needs Java worker spec for multi-language ROI
2. **Unknowns ranking**: 5-factor formula too complex; centrality graphs expensive; needs simplification
3. **Integration gaps**: No Smart-Diff integration, incomplete air-gap bundle spec, missing UI wireframes
4. **Schema design**: No schema isolation guidance, incomplete indexes, no partitioning plan for high-volume tables
5. **Rekor scalability**: Edge-bundle attestations need budget policy to avoid transparency log flooding

## Schema Assignments
Per `docs/07_HIGH_LEVEL_ARCHITECTURE.md` schema isolation:
| Schema | Tables | Owner Module | Purpose |
|--------|--------|--------------|---------|
| `scanner` | `scan_manifest`, `proof_bundle`, `cg_node`, `cg_edge`, `entrypoint`, `runtime_sample` | Scanner.WebService | Scan orchestration, call-graphs, proof bundles |
| `policy` | `reachability_component`, `reachability_finding`, `unknowns`, `proof_segments` | Policy.Engine | Reachability verdicts, unknowns queue, score proofs |
| `shared` | `symbol_component_map` | Scanner + Policy | SBOM component to symbol mapping |
**Migration Path**:
- Sprint 3500.0002.0002: Create `scanner` schema tables (manifest, proof_bundle)
- Sprint 3500.0002.0003: Create `policy` schema tables (proof_segments, unknowns)
- Sprint 3500.0003.0002: Create `scanner` schema call-graph tables (cg_node, cg_edge)
- Sprint 3500.0003.0003: Create `policy` schema reachability tables
---
## Index Strategy
**High-Priority Indexes** (15 total):
```sql
-- scanner schema
CREATE INDEX idx_scan_manifest_artifact ON scanner.scan_manifest(artifact_digest);
CREATE INDEX idx_scan_manifest_snapshots ON scanner.scan_manifest(concelier_snapshot_hash, excititor_snapshot_hash);
CREATE INDEX idx_proof_bundle_scan ON scanner.proof_bundle(scan_id);
CREATE INDEX idx_cg_edge_from ON scanner.cg_edge(scan_id, from_node_id);
CREATE INDEX idx_cg_edge_to ON scanner.cg_edge(scan_id, to_node_id);
CREATE INDEX idx_cg_edge_kind ON scanner.cg_edge(scan_id, kind) WHERE kind = 'static';
CREATE INDEX idx_entrypoint_scan ON scanner.entrypoint(scan_id);
CREATE INDEX idx_runtime_sample_scan ON scanner.runtime_sample(scan_id, collected_at DESC);
CREATE INDEX idx_runtime_sample_frames ON scanner.runtime_sample USING GIN(frames);
-- policy schema
CREATE INDEX idx_unknowns_score ON policy.unknowns(score DESC) WHERE band = 'HOT';
CREATE INDEX idx_unknowns_pkg ON policy.unknowns(pkg_id, pkg_version);
CREATE INDEX idx_reachability_finding_scan ON policy.reachability_finding(scan_id, status);
CREATE INDEX idx_proof_segments_spine ON policy.proof_segments(spine_id, idx);
-- shared schema
CREATE INDEX idx_symbol_component_scan ON shared.symbol_component_map(scan_id, node_id);
CREATE INDEX idx_symbol_component_purl ON shared.symbol_component_map(purl);
```
---
## Partition Strategy
**High-Volume Tables** (>1M rows expected):
| Table | Partition Key | Partition Interval | Retention |
|-------|--------------|-------------------|-----------|
| `scanner.runtime_sample` | `collected_at` | Monthly | 90 days (drop old partitions) |
| `scanner.cg_edge` | `scan_id` (hash) | By tenant or scan_id range | 180 days |
| `policy.proof_segments` | `created_at` | Monthly | 365 days (compliance) |
**Implementation**: Sprint 3500.0003.0004 (partitioning for scale)
---
## Air-Gap Bundle Extensions
Extend `docs/24_OFFLINE_KIT.md` with new bundle types:
### Reachability Bundle
```
/offline/reachability/<scan-id>/
├── callgraph.json.zst # Compressed call-graph
├── manifest.json # Scan manifest
├── manifest.dsse.json # DSSE signature
└── proofs/
├── score_proof.cbor # Canonical proof ledger
└── reachability_proof.json # Reachability verdicts
```
### Ground-Truth Corpus Bundle
```
/offline/corpus/ground-truth-v1.tar.zst
├── corpus-manifest.json # Corpus metadata
├── samples/
│ ├── 001_reachable_vuln/ # Known reachable case
│ ├── 002_unreachable_vuln/ # Known unreachable case
│ └── ...
└── expected_results.json # Golden assertions
```
**Implementation**: Sprint 3500.0002.0004 (offline bundles)
---
## Integration with Existing Systems
### Smart-Diff Integration
**Requirement**: Score proofs must integrate with Smart-Diff classification tracking.
**Design**:
- ProofLedger snapshots keyed by `(scan_id, graph_revision_id)`
- Score replay reconstructs ledger **as of a specific graph revision**
- Smart-Diff UI shows **score trajectory** alongside reachability classification changes
**Tables**:
```sql
-- Add to policy schema
CREATE TABLE policy.score_history (
scan_id uuid,
graph_revision_id text,
finding_id text,
score_proof_root_hash text,
score_value decimal(5,2),
created_at timestamptz,
PRIMARY KEY (scan_id, graph_revision_id, finding_id)
);
```
**Implementation**: Sprint 3500.0002.0005 (Smart-Diff integration)
### Hybrid Reachability Attestations
Per `docs/modules/platform/architecture-overview.md:89`:
> Scanner/Attestor always publish graph-level DSSE for reachability graphs; optional edge-bundle DSSEs capture high-risk/runtime/init edges.
**Rekor Budget Policy**:
- **Default**: Graph-level DSSE only (1 Rekor entry per scan)
- **Escalation triggers**: Emit edge bundles when:
- `risk_score > 0.7` (critical findings)
- `contested=true` (disputed reachability claims)
- `runtime_evidence_exists=true` (runtime contradicts static analysis)
- **Batch size limits**: Max 100 edges per bundle
- **Offline verification**: Edge bundles stored in proof bundle for air-gap replay
**Implementation**: Sprint 3500.0003.0005 (hybrid attestations)

**Wireframes**: Product team to deliver by Sprint 3500.0002 start
**Implementation**: Sprint 3500.0004.0002 (UI components)
---
## Testing Strategy
### Unit Tests
**Coverage targets**: ≥85% for all new code
**Key test suites**:
- `CanonicalJsonTests` — JSON canonicalization, deterministic hashing
- `DsseEnvelopeTests` — PAE encoding, signature verification
- `ProofLedgerTests` — Node hashing, root hash computation
- `ScoringTests` — Deterministic scoring with all evidence types
- `UnknownsRankerTests` — 2-factor ranking formula, band assignment
- `ReachabilityTests` — BFS algorithm, path reconstruction
### Integration Tests
**Required scenarios** (10 total):
1. Full SBOM → scan → proof chain → replay
2. Score replay produces identical proof root hash
3. Unknowns ranking deterministic across runs
4. Call-graph extraction (.NET) → reachability → DSSE
5. Call-graph extraction (Java) → reachability → DSSE
6. Rescan with new Concelier snapshot → score delta
7. Smart-Diff classification change → proof history
8. Offline bundle export → air-gap verification
9. Rekor attestation → inclusion proof verification
10. DSSE signature tampering → verification failure
### Golden Corpus
**Mandatory test cases** (per `docs/product-advisories/14-Dec-2025 - Reachability Analysis Technical Reference.md:815`):
1. ASP.NET controller with reachable endpoint → vulnerable lib call
2. Vulnerable lib present but never called → unreachable
3. Reflection-based activation → possibly_reachable
4. BackgroundService job case
5. Version range ambiguity
6. Mismatched epoch/backport
7. Missing CVSS vector
8. Conflicting severity vendor/NVD
9. Unanchored filesystem library
**Corpus location**: `/offline/corpus/ground-truth-v1/`
**Implementation**: Sprint 3500.0002.0006 (test infrastructure)
---
## Deferred to Phase 2
**Not in scope for Sprints 3500.0001-3500.0004**:
1. **Graph centrality ranking** (Unknowns factor `C`) — Expensive; needs real telemetry first
2. **Edge-bundle attestations** — Wait for Rekor budget policy refinement
3. **Runtime evidence integration** (`runtime_sample` table) — Needs Zastava maturity
4. **Multi-arch support** (arm64, Mach-O) — After .NET+Java v1 proves value
5. **Python/Go/Rust reachability** — Language-specific workers in Phase 2
6. **Snippet/harness generator** — IR transcripts only in v1

# Sprint 3500.0003.0001 · Ground-Truth Corpus & CI Regression Gates
## Topic & Scope
Establish the ground-truth corpus for binary-only reachability benchmarking and CI regression gates. This sprint delivers:
1. **Corpus Structure** - 20 curated binaries with known reachable/unreachable sinks
2. **Benchmark Runner** - CLI/API to run corpus and emit metrics JSON
3. **CI Regression Gates** - Fail build on precision/recall/determinism regressions
4. **Baseline Management** - Tooling to update baselines when improvements land
**Source Advisory**: `docs/product-advisories/unprocessed/16-Dec-2025 - Building a Deeper Moat Beyond Reachability.md`
**Related Docs**: `docs/benchmarks/ground-truth-corpus.md` (new)
**Working Directory**: `bench/reachability-benchmark/`, `datasets/reachability/`, `src/Scanner/`
## Dependencies & Concurrency
- **Depends on**: Binary reachability v1 engine (future sprint, can stub for now)
- **Blocking**: Moat validation demos; PR regression feedback
- **Safe to parallelize with**: Score replay sprint, Unknowns ranking sprint
## Documentation Prerequisites
- `docs/README.md`
- `docs/benchmarks/ground-truth-corpus.md`
- `docs/product-advisories/14-Dec-2025 - Reachability Analysis Technical Reference.md`
- `bench/README.md`

## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-17 | Sprint created from advisory "Building a Deeper Moat Beyond Reachability" | Planning |
| 2025-12-17 | CORPUS-001: Created corpus-sample.v1.json schema with sink definitions, categories, and validation | Agent |
| 2025-12-17 | CORPUS-004: Created corpus.json index with 20 samples across 6 categories | Agent |
| 2025-12-17 | CORPUS-005: Created ICorpusRunner.cs with benchmark execution interfaces and models | Agent |
| 2025-12-17 | CORPUS-006: Created BenchmarkResultWriter.cs with metrics calculation and markdown reports | Agent |
| 2025-12-17 | CORPUS-013: Created CorpusRunnerIntegrationTests.cs with comprehensive tests for corpus runner | Agent |
---
## Decisions & Risks
- **Risk**: Creating ground-truth binaries requires cross-compilation for multiple archs. Mitigation: Start with x86_64 ELF only; expand in later phase.
- **Decision**: Corpus samples are synthetic (crafted) not real-world; real-world validation is a separate effort.
- **Pending**: Need to define exact source code templates for injecting known reachable/unreachable sinks.
---
## Next Checkpoints
- [ ] Corpus sample review with Scanner team
- [ ] CI workflow review with DevOps team

# Sprint 3600.0002.0001 · Unknowns Ranking with Containment Signals
## Topic & Scope
Enhance the Unknowns ranking model with blast radius and runtime containment signals from the "Building a Deeper Moat Beyond Reachability" advisory. This sprint delivers:
1. **Enhanced Unknown Data Model** - Add blast radius, containment signals, exploit pressure
2. **Containment-Aware Ranking** - Reduce scores for well-sandboxed findings
3. **Unknown Proof Trail** - Emit proof nodes explaining rank factors
4. **API: `/unknowns/list?sort=score`** - Expose ranked unknowns
**Source Advisory**: `docs/product-advisories/unprocessed/16-Dec-2025 - Building a Deeper Moat Beyond Reachability.md`
**Related Docs**: `docs/product-advisories/14-Dec-2025 - Triage and Unknowns Technical Reference.md` §17.5
**Working Directory**: `src/Scanner/__Libraries/StellaOps.Scanner.Unknowns/`, `src/Scanner/StellaOps.Scanner.WebService/`
## Dependencies & Concurrency
- **Depends on**: SPRINT_3420_0001_0001 (Bitemporal Unknowns Schema) - provides base unknowns table
- **Depends on**: Runtime signal ingestion (containment facts must be available)
- **Blocking**: Quiet-update UX for unknowns in UI
- **Safe to parallelize with**: Score replay sprint, Ground-truth corpus sprint
## Documentation Prerequisites
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/product-advisories/14-Dec-2025 - Triage and Unknowns Technical Reference.md`
- `docs/modules/scanner/architecture.md`

## Technical Specifications
### Enhanced Unknown Model
```csharp
public sealed record UnknownItem(
string Id,
string ArtifactDigest,
string ArtifactPurl,
string[] Reasons, // ["missing_vex", "ambiguous_indirect_call", ...]
BlastRadius BlastRadius,
double EvidenceScarcity, // 0..1
ExploitPressure ExploitPressure,
ContainmentSignals Containment,
double Score, // 0..1
string ProofRef // path inside proof bundle
);
public sealed record BlastRadius(int Dependents, bool NetFacing, string Privilege);
public sealed record ExploitPressure(double? Epss, bool Kev);
public sealed record ContainmentSignals(string Seccomp, string Fs);
```
### Ranking Function
```csharp
public static double Rank(BlastRadius b, double scarcity, ExploitPressure ep, ContainmentSignals c)
{
// Blast radius: 60% weight
var dependents01 = Math.Clamp(b.Dependents / 50.0, 0, 1);
var net = b.NetFacing ? 0.5 : 0.0;
var priv = b.Privilege == "root" ? 0.5 : 0.0;
var blast = Math.Clamp((dependents01 + net + priv) / 2.0, 0, 1);
// Exploit pressure: 30% weight
var epss01 = ep.Epss ?? 0.35;
var kev = ep.Kev ? 0.30 : 0.0;
var pressure = Math.Clamp(epss01 + kev, 0, 1);
// Containment deductions
var containment = 0.0;
if (c.Seccomp == "enforced") containment -= 0.10;
if (c.Fs == "ro") containment -= 0.10;
return Math.Clamp(0.60 * blast + 0.30 * scarcity + 0.30 * pressure + containment, 0, 1);
}
```
### Unknown Proof Node
Each unknown emits a mini proof ledger identical to score proofs:
- Input node: reasons + evidence scarcity facts
- Delta nodes: blast/pressure/containment components
- Score node: final unknown score
Stored at: `proofs/unknowns/{unkId}/tree.json`

## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-17 | Sprint created from advisory "Building a Deeper Moat Beyond Reachability" | Planning |
| 2025-12-17 | UNK-RANK-004: Created UnknownProofEmitter.cs with proof ledger emission for ranking decisions | Agent |
| 2025-12-17 | UNK-RANK-007,008: Created UnknownsEndpoints.cs with GET /unknowns API, sorting, pagination, and filtering | Agent |
---
## Decisions & Risks
- **Risk**: Containment signals require runtime data ingestion (eBPF/LSM events). If unavailable, default to "unknown" which adds no deduction.
- **Decision**: Start with seccomp and read-only FS signals; add eBPF/LSM denies in future sprint.
- **Pending**: Confirm runtime signal ingestion pipeline availability.
---
## Next Checkpoints
- [ ] Schema review with DB team
- [ ] Runtime signal ingestion design review
- [ ] UI mockups for unknowns cards with blast radius indicators

# EPSS Integration Architecture
> **Advisory Source**: `docs/product-advisories/16-Dec-2025 - Merging EPSS v4 with CVSS v4 Frameworks.md`
> **Last Updated**: 2025-12-17
> **Status**: Approved for Implementation
---
## Executive Summary
EPSS (Exploit Prediction Scoring System) is a **probabilistic model** that estimates the likelihood a given CVE will be exploited in the wild over the next ~30 days. This document defines how StellaOps integrates EPSS as a first-class risk signal.
**Key Distinction**:
- **CVSS v4**: Deterministic measurement of *severity* (0-10)
- **EPSS**: Dynamic, data-driven *probability of exploitation* (0-1)
EPSS does **not** replace CVSS or VEX—it provides complementary probabilistic threat intelligence.
---
## 1. Design Principles
### 1.1 EPSS as Probabilistic Signal
| Signal Type | Nature | Source |
|-------------|--------|--------|
| CVSS v4 | Deterministic impact | NVD, vendor |
| EPSS | Probabilistic threat | FIRST daily feeds |
| VEX | Vendor intent | Vendor statements |
| Runtime context | Actual exposure | StellaOps scanner |
**Rule**: EPSS *modulates confidence*, never asserts truth.
### 1.2 Architectural Constraints
1. **Append-only time-series**: Never overwrite historical EPSS data
2. **Deterministic replay**: Every scan stores the EPSS snapshot reference used
3. **Idempotent ingestion**: Safe to re-run for same date
4. **Postgres as source of truth**: Valkey is optional cache only
5. **Air-gap compatible**: Manual import via signed bundles
---
## 2. Data Model
### 2.1 Core Tables
#### Import Provenance
```sql
CREATE TABLE epss_import_runs (
import_run_id UUID PRIMARY KEY,
model_date DATE NOT NULL,
source_uri TEXT NOT NULL,
retrieved_at TIMESTAMPTZ NOT NULL,
file_sha256 TEXT NOT NULL,
decompressed_sha256 TEXT NULL,
row_count INT NOT NULL,
model_version_tag TEXT NULL,
published_date DATE NULL,
status TEXT NOT NULL, -- SUCCEEDED / FAILED
error TEXT NULL,
UNIQUE (model_date)
);
```
#### Time-Series Scores (Partitioned)
```sql
CREATE TABLE epss_scores (
model_date DATE NOT NULL,
cve_id TEXT NOT NULL,
epss_score DOUBLE PRECISION NOT NULL,
percentile DOUBLE PRECISION NOT NULL,
import_run_id UUID NOT NULL REFERENCES epss_import_runs(import_run_id),
PRIMARY KEY (model_date, cve_id)
) PARTITION BY RANGE (model_date);
```
#### Current Projection (Fast Lookup)
```sql
CREATE TABLE epss_current (
cve_id TEXT PRIMARY KEY,
epss_score DOUBLE PRECISION NOT NULL,
percentile DOUBLE PRECISION NOT NULL,
model_date DATE NOT NULL,
import_run_id UUID NOT NULL
);
CREATE INDEX idx_epss_current_score_desc ON epss_current (epss_score DESC);
CREATE INDEX idx_epss_current_percentile_desc ON epss_current (percentile DESC);
```
#### Change Detection
```sql
CREATE TABLE epss_changes (
model_date DATE NOT NULL,
cve_id TEXT NOT NULL,
old_score DOUBLE PRECISION NULL,
new_score DOUBLE PRECISION NOT NULL,
delta_score DOUBLE PRECISION NULL,
old_percentile DOUBLE PRECISION NULL,
new_percentile DOUBLE PRECISION NOT NULL,
flags INT NOT NULL, -- bitmask: NEW_SCORED, CROSSED_HIGH, BIG_JUMP
PRIMARY KEY (model_date, cve_id)
) PARTITION BY RANGE (model_date);
```
### 2.2 Flags Bitmask
| Flag | Value | Meaning |
|------|-------|---------|
| NEW_SCORED | 0x01 | CVE newly scored (not in previous day) |
| CROSSED_HIGH | 0x02 | Score crossed above high threshold |
| CROSSED_LOW | 0x04 | Score crossed below high threshold |
| BIG_JUMP_UP | 0x08 | Delta > 0.10 upward |
| BIG_JUMP_DOWN | 0x10 | Delta > 0.10 downward |
| TOP_PERCENTILE | 0x20 | Entered top 5% |

```
| Component | Responsibility |
|-----------|----------------|
| **Scheduler** | Triggers daily EPSS import job |
| **Concelier** | Downloads/imports EPSS, stores facts, computes delta, emits events |
| **Scanner** | Attaches EPSS-at-scan as immutable evidence, uses for scoring |
| **Excititor** | Creates VEX tasks when EPSS is high and VEX missing |
| **Notify** | Sends alerts on priority changes |
### 3.2 Event Flow
```
Scheduler
→ epss.ingest(date)
→ Concelier (ingest)
→ epss.updated
→ Notify (optional daily summary)
→ Concelier (enrichment)
→ vuln.priority.changed
→ Notify (targeted alerts)
→ Excititor (VEX task creation)
```
---
## 4. Ingestion Pipeline
### 4.1 Data Source
FIRST publishes daily CSV snapshots at:
```
https://epss.empiricalsecurity.com/epss_scores-YYYY-MM-DD.csv.gz
```
Each file contains ~300k CVE records with:
- `cve` - CVE ID
- `epss` - Score (0.00000–1.00000)
- `percentile` - Rank vs all CVEs
### 4.2 Ingestion Steps
1. **Scheduler** triggers daily job for date D
2. **Download** `epss_scores-D.csv.gz`
3. **Decompress** stream
4. **Parse** header comment for model version/date
5. **Validate** scores in [0,1], monotonic percentile
6. **Bulk load** into TEMP staging table
7. **Transaction**:
- Insert `epss_import_runs`
- Insert into `epss_scores` partition
- Compute `epss_changes` by comparing staging vs `epss_current`
- Upsert `epss_current`
- Enqueue `epss.updated` event
8. **Commit**
### 4.3 Air-Gap Import
Accept local bundle containing:
- `epss_scores-YYYY-MM-DD.csv.gz`
- `manifest.json` with sha256, source attribution, DSSE signature
Same pipeline, with `source_uri = bundle://...`.
---
## 5. Enrichment Rules
### 5.1 New Scan Findings (Immutable)
Store EPSS "as-of" scan time:
```csharp
public record ScanEpssEvidence
{
public double EpssScoreAtScan { get; init; }
public double EpssPercentileAtScan { get; init; }
public DateOnly EpssModelDateAtScan { get; init; }
public Guid EpssImportRunIdAtScan { get; init; }
}
```
This supports deterministic replay even if EPSS changes later.
### 5.2 Existing Findings (Live Triage)
Maintain mutable "current EPSS" on vulnerability instances:
- **scan_finding_evidence**: Immutable EPSS-at-scan
- **vuln_instance_triage**: Current EPSS + band (for live triage)
### 5.3 Efficient Delta Targeting
On `epss.updated(D)`:
1. Read `epss_changes` where flags indicate material change
2. Find impacted vulnerability instances by CVE
3. Update only those instances
4. Emit `vuln.priority.changed` only if band crossed
---
## 6. Notification Policy
### 6.1 Default Thresholds
| Threshold | Default | Description |
|-----------|---------|-------------|
| HighPercentile | 0.95 | Top 5% of all CVEs |
| HighScore | 0.50 | 50% exploitation probability |
| BigJumpDelta | 0.10 | Meaningful daily change |
### 6.2 Trigger Conditions
1. **Newly scored** CVE in inventory AND `percentile >= HighPercentile`
2. Existing CVE **crosses above** HighPercentile or HighScore
3. Delta > BigJumpDelta AND CVE in runtime-exposed assets
All thresholds are org-configurable.
---
## 7. Trust Lattice Integration
### 7.1 Scoring Rule Example
```
IF cvss_base >= 8.0
AND epss_score >= 0.35
AND runtime_exposed = true
→ priority = IMMEDIATE_ATTENTION
```
### 7.2 Score Weights
| Factor | Default Weight | Range |
|--------|---------------|-------|
| CVSS | 0.25 | 0.0-1.0 |
| EPSS | 0.25 | 0.0-1.0 |
| Reachability | 0.25 | 0.0-1.0 |
| Freshness | 0.15 | 0.0-1.0 |
| Frequency | 0.10 | 0.0-1.0 |
---
## 8. API Surface
### 8.1 Internal API Endpoints
| Endpoint | Description |
|----------|-------------|
| `GET /epss/current?cve=...` | Bulk lookup current EPSS |
| `GET /epss/history?cve=...&days=180` | Historical time-series |
| `GET /epss/top?order=epss&limit=100` | Top CVEs by score |
| `GET /epss/changes?date=...` | Daily change report |
### 8.2 UI Requirements
For each vulnerability instance:
- EPSS score + percentile
- Model date
- Trend delta vs previous scan date
- Filter chips: "High EPSS", "Rising EPSS", "High CVSS + High EPSS"
- Evidence panel showing EPSS-at-scan vs current EPSS
---
## 9. Implementation Checklist
### Phase 1: Data Foundation
- [ ] DB migrations: tables + partitions + indexes
- [ ] Concelier ingestion job: online download + bundle import
### Phase 2: Integration
- [ ] epss_current + epss_changes projection
- [ ] Scanner.WebService: attach EPSS-at-scan evidence
- [ ] Bulk lookup API
### Phase 3: Enrichment
- [ ] Concelier enrichment job: update triage projections
- [ ] Notify subscription to vuln.priority.changed
### Phase 4: UI/UX
- [ ] EPSS fields in vulnerability detail
- [ ] Filters and sort by exploit likelihood
- [ ] Trend visualization
### Phase 5: Operations
- [ ] Backfill tool (last 180 days)
- [ ] Ops runbook: schedules, manual re-run, air-gap import
---
## 10. Anti-Patterns to Avoid
| Anti-Pattern | Why It's Wrong |
|--------------|----------------|
| Storing only latest EPSS | Breaks auditability and replay |
| Mixing EPSS into CVE table | EPSS is signal, not vulnerability data |
| Treating EPSS as severity | EPSS is probability, not impact |
| Alerting on every daily fluctuation | Creates alert fatigue |
| Recomputing EPSS internally | Use FIRST's authoritative data |

# Key Rotation Runbook
> **Module**: Signer / Key Management
> **Version**: 1.0.0
> **Last Updated**: 2025-12-17
This runbook describes procedures for managing signing key lifecycle in StellaOps, including key rotation, revocation, and trust anchor management.
---
## Overview
StellaOps uses signing keys to create DSSE envelopes for proof chain attestations. Key rotation is critical for:
- Limiting exposure from compromised keys
- Compliance with key age policies (e.g., NIST SP 800-57)
- Transitioning between cryptographic algorithms
### Key Principles
1. **Never mutate old DSSE envelopes** - Signed content is immutable
2. **Never remove keys from history** - Move to `revokedKeys`, don't delete
3. **Publish key material** - Via attestation feed or Rekor-mirror
4. **Audit all changes** - Full log of key lifecycle events
5. **Maintain key version history** - For forensic verification
---
## Signing Key Profiles
StellaOps supports multiple signing key profiles for different security requirements:
| Profile | Algorithm | Key Store | Use Case |
|---------|-----------|-----------|----------|
| `default` | SHA256-ED25519 | AWS KMS | Standard production |
| `fips` | SHA256-ECDSA-P256 | HSM (PKCS#11) | FIPS 140-2 environments |
| `gost` | GOST-R-34.10-2012 | Local HSM | Russian regulatory |
| `sm2` | SM2-P256 | Local HSM | Chinese regulatory |
| `pqc` | ML-DSA-65 | Software | Post-quantum ready |
### Profile Configuration
```yaml
# /etc/stellaops/signer.yaml
signer:
profiles:
default:
algorithm: "SHA256-ED25519"
keyStore: "kms://aws/key/stellaops-default"
rotation:
enabled: true
maxAgeMonths: 12
warningMonths: 2
fips:
algorithm: "SHA256-ECDSA-P256"
keyStore: "hsm://pkcs11/slot/0"
rotation:
enabled: true
maxAgeMonths: 12
warningMonths: 2
```
---
## Key Rotation Workflow
### Step 1: Generate New Key
Generate a new signing key in the configured key store:
```bash
# Using CLI
stellaops key generate \
--profile default \
--key-id key-2025-prod \
--algorithm SHA256-ED25519
# Via API
curl -X POST https://api.stellaops.local/v1/signer/keys \
-H "Authorization: Bearer $TOKEN" \
-d '{"profile": "default", "keyId": "key-2025-prod", "algorithm": "SHA256-ED25519"}'
```
### Step 2: Add Key to Trust Anchor
Add the new key to the trust anchor without removing the old key:
```bash
# Using CLI
stellaops anchor add-key \
--anchor-id 550e8400-e29b-41d4-a716-446655440000 \
--key-id key-2025-prod
# Via API
curl -X POST https://api.stellaops.local/v1/anchors/550e8400.../keys \
-H "Authorization: Bearer $TOKEN" \
-d '{"keyid": "key-2025-prod", "publicKey": "<pem-encoded>"}'
```
**Result:** Trust anchor now accepts signatures from both old and new keys.
### Step 3: Transition Period
During transition:
- New signatures are created with the new key
- Old proofs are verified with either key
- Monitor for verification failures
**Recommended transition period:** 2-4 weeks
```bash
# Check verification status
stellaops anchor status --anchor-id 550e8400...
# Expected output:
# Anchor: 550e8400-e29b-41d4-a716-446655440000
# Active Keys: key-2024-prod, key-2025-prod
# Verification Success Rate: 100%
# Pending Rescans: 0
```
### Step 4: Revoke Old Key (Optional)
After transition is complete, revoke the old key:
```bash
# Using CLI
stellaops anchor revoke-key \
--anchor-id 550e8400... \
--key-id key-2024-prod \
--reason "annual-rotation" \
--effective-at "2025-02-01T00:00:00Z"
# Via API
curl -X POST https://api.stellaops.local/v1/anchors/550e8400.../keys/key-2024-prod/revoke \
-H "Authorization: Bearer $TOKEN" \
-d '{"reason": "annual-rotation", "effectiveAt": "2025-02-01T00:00:00Z"}'
```
**Important:** The old key remains valid for verifying proofs signed before the revocation date.
### Step 5: Publish Key Material
Publish updated key material:
```bash
# Update attestation feed
stellaops feed publish --include-keys
# Sync to Rekor mirror (if applicable)
stellaops rekor sync --keys-only
```
---
## Trust Anchor Management
### Trust Anchor Structure
```json
{
"trustAnchorId": "550e8400-e29b-41d4-a716-446655440000",
"purlPattern": "pkg:npm/*",
"allowedKeyids": ["key-2024-prod", "key-2025-prod"],
"allowedPredicateTypes": [
"evidence.stella/v1",
"reasoning.stella/v1",
"cdx-vex.stella/v1",
"proofspine.stella/v1"
],
"policyVersion": "v2.3.1",
"revokedKeys": ["key-2023-prod"],
"keyHistory": [
{
"keyid": "key-2023-prod",
"addedAt": "2023-01-15T00:00:00Z",
"revokedAt": "2024-01-15T00:00:00Z",
"revokeReason": "annual-rotation"
}
]
}
```
### Create Trust Anchor
```bash
stellaops anchor create \
--purl-pattern "pkg:npm/*" \
--key-ids key-2025-prod \
--predicate-types evidence.stella/v1,reasoning.stella/v1
```
### List Trust Anchors
```bash
stellaops anchor list
# Output:
# ID Pattern Keys Status
# 550e8400-e29b-41d4-a716-446655440000 pkg:npm/* key-2025-prod active
# 660f9500-f39c-51e5-b827-557766551111 pkg:maven/* key-2025-java active
```
### PURL Pattern Matching
Trust anchors use PURL patterns for scope:
| Pattern | Matches |
|---------|---------|
| `pkg:npm/*` | All npm packages |
| `pkg:maven/org.apache.*` | Apache Maven packages |
| `pkg:docker/myregistry/*` | All images from myregistry |
| `*` | Universal (all packages) |
---
## Verification with Key History
When verifying a proof signed at time T:
1. Lookup trust anchor for the artifact PURL
2. Find keys that were valid at time T:
- Key was added before T
- Key was not revoked, OR revoked after T
3. Verify signature against valid keys
4. Return success if any valid key verifies
### Temporal Verification
```bash
# Verify proof at specific point in time
stellaops verify \
--proof-bundle sha256:abc123... \
--at-time "2024-06-15T12:00:00Z"
# Check key validity at time
stellaops key check-validity \
--key-id key-2024-prod \
--at-time "2024-06-15T12:00:00Z"
```
---
## Emergency Key Revocation
In case of key compromise:
### Immediate Actions
1. **Revoke the compromised key immediately**
```bash
stellaops anchor revoke-key \
--anchor-id ALL \
--key-id compromised-key-id \
--reason "compromise" \
--effective-at "NOW"
```
2. **Generate new key**
```bash
stellaops key generate \
--profile default \
--key-id emergency-key-$(date +%Y%m%d)
```
3. **Add new key to all affected anchors**
```bash
stellaops anchor add-key \
--anchor-id ALL \
--key-id emergency-key-$(date +%Y%m%d)
```
4. **Publish updated key material**
```bash
stellaops feed publish --include-keys --urgent
```
### Post-Incident Actions
1. Review all proofs signed with compromised key
2. Determine if any tampering occurred
3. Re-sign critical proofs with new key if needed
4. File incident report
---
## Rotation Warnings
Configure rotation warnings to proactively manage key lifecycle:
```yaml
signer:
rotation:
warningMonths: 2
alerts:
- type: slack
channel: "#security-ops"
- type: email
recipients: ["security@example.com"]
```
### Check Rotation Warnings
```bash
stellaops key rotation-warnings
# Output:
# Key ID Profile Age Max Age Warning
# key-2024-prod default 10mo 12mo ⚠️ Rotation due in 2 months
# key-2024-java fips 6mo 12mo ✓ OK
```
---
## Audit Trail
All key operations are logged to `key_audit_log`:
| Field | Description |
|-------|-------------|
| `event_id` | Unique event identifier |
| `event_type` | `KEY_GENERATED`, `KEY_ADDED`, `KEY_REVOKED`, etc. |
| `key_id` | Affected key identifier |
| `anchor_id` | Affected trust anchor (if applicable) |
| `actor` | User/service that performed action |
| `timestamp` | UTC timestamp |
| `details` | JSON with additional context |
### Query Audit Log
```bash
stellaops audit query \
--type KEY_* \
--from "2025-01-01" \
--to "2025-12-31"
# Via SQL
SELECT * FROM signer.key_audit_log
WHERE event_type LIKE 'KEY_%'
AND timestamp >= '2025-01-01'
ORDER BY timestamp DESC;
```

## 11.2 SCORE PROOF LEDGER
> **Added**: 2025-12-17 from "Building a Deeper Moat Beyond Reachability" advisory
The Score Proof Ledger provides an append-only trail of scoring decisions with per-node hashing.
### Proof Node Types
```csharp
public enum ProofNodeKind { Input, Transform, Delta, Score }
public sealed record ProofNode(
string Id,
ProofNodeKind Kind,
string RuleId,
string[] ParentIds,
string[] EvidenceRefs, // digests / refs inside bundle
double Delta, // 0 for non-Delta nodes
double Total, // running total at this node
string Actor, // module name
DateTimeOffset TsUtc,
byte[] Seed,
string NodeHash // sha256 over canonical node (excluding NodeHash)
);
```
### Proof Hashing
```csharp
public static class ProofHashing
{
public static ProofNode WithHash(ProofNode n)
{
var canonical = CanonJson.Canonicalize(new
{
n.Id, n.Kind, n.RuleId, n.ParentIds, n.EvidenceRefs, n.Delta, n.Total,
n.Actor, n.TsUtc, Seed = Convert.ToBase64String(n.Seed)
});
return n with { NodeHash = "sha256:" + CanonJson.Sha256Hex(canonical) };
}
public static string ComputeRootHash(IEnumerable<ProofNode> nodesInOrder)
{
// Deterministic: root hash over canonical JSON array of node hashes in order.
var arr = nodesInOrder.Select(n => n.NodeHash).ToArray();
var bytes = CanonJson.Canonicalize(arr);
return "sha256:" + CanonJson.Sha256Hex(bytes);
}
}
```
### Minimal Ledger
```csharp
public sealed class ProofLedger
{
private readonly List<ProofNode> _nodes = new();
public IReadOnlyList<ProofNode> Nodes => _nodes;
public void Append(ProofNode node)
{
_nodes.Add(ProofHashing.WithHash(node));
}
public string RootHash() => ProofHashing.ComputeRootHash(_nodes);
}
```
### Score Replay Invariant
The score replay must produce identical ledger root hashes given:
- Same manifest (artifact, snapshots, policy)
- Same seed
- Same timestamp (or frozen clock)
```csharp
public class DeterminismTests
{
[Fact]
public void Score_Replay_IsBitIdentical()
{
var seed = Enumerable.Repeat((byte)7, 32).ToArray();
var inputs = new ScoreInputs(9.0, 0.50, false, ReachabilityClass.Unknown, new("enforced","ro"));
var (s1, l1) = RiskScoring.Score(inputs, "scanA", seed, DateTimeOffset.Parse("2025-01-01T00:00:00Z"));
var (s2, l2) = RiskScoring.Score(inputs, "scanA", seed, DateTimeOffset.Parse("2025-01-01T00:00:00Z"));
Assert.Equal(s1, s2, 10);
Assert.Equal(l1.RootHash(), l2.RootHash());
Assert.True(l1.Nodes.Zip(l2.Nodes).All(z => z.First.NodeHash == z.Second.NodeHash));
}
}
