# Drift CLI Reference
**Sprint:** SPRINT_3600_0004_0001
**Task:** UI-024 - Update CLI documentation for drift commands
## Overview
The Drift CLI provides commands for detecting and analyzing reachability drift between scan results. Reachability drift occurs when the call paths to vulnerable code change between builds, potentially altering the risk profile of an application.
## Commands
### stellaops drift
Parent command for reachability drift operations.
```bash
stellaops drift <SUBCOMMAND> [OPTIONS]
```
---
### stellaops drift compare
Compare reachability between two scans or graph snapshots.
```bash
stellaops drift compare [OPTIONS]
```
#### Required Options
| Option | Alias | Description |
|--------|-------|-------------|
| `--base <ID>` | `-b` | Base scan/graph ID or commit SHA for comparison |
#### Optional Options

```bash
stellaops drift compare --base abc123 --output json > drift.json
```
##### Output as SARIF for CI integration
```bash
stellaops drift compare --base abc123 --output sarif > drift.sarif
```

# Vuln Surface Contract v1
**Sprint:** SPRINT_3700_0002_0001
**Task:** SURF-024
**Schema:** `stella.ops/vulnSurface@v1`
## Overview
A Vulnerability Surface represents the specific methods that changed between a vulnerable and fixed version of a package. This enables precise reachability analysis by identifying the exact "trigger" methods that are dangerous rather than treating the entire package as vulnerable.
## Use Cases
1. **Noise Reduction** - Only flag findings where code actually calls vulnerable methods
2. **Confidence Tiers** - "Confirmed reachable" (calls trigger) vs "Potentially reachable" (uses package)
3. **Remediation Guidance** - Show developers exactly which API calls to avoid
4. **VEX Precision** - Automatically generate VEX "not_affected" for unreachable triggers
## Data Model

# Witness Schema v1 Contract
> **Version**: `stellaops.witness.v1`
> **Status**: Draft
> **Sprint**: `SPRINT_3700_0001_0001_witness_foundation`
---
## Overview
A **witness** is a cryptographically-signed proof of a reachability path from an entrypoint to a vulnerable sink. Witnesses provide:
1. **Auditability** - Proof that a path was found at scan time
2. **Offline verification** - Verify claims without re-running analysis
3. **Provenance** - Links to the source graph and analysis context
4. **Transparency** - Can be published to transparency logs

## Hash Computation
The `witness_hash` is computed as:
1. Serialize the witness to canonical JSON (sorted keys, no whitespace)
2. Exclude `witness_id`, `witness_hash`, and `created_at` fields
3. Compute BLAKE3 hash of the canonical bytes
4. Prefix with `blake3:` and hex-encode
```csharp
var canonical = JsonSerializer.Serialize(witness, canonicalOptions);
var hash = Blake3.Hasher.Hash(Encoding.UTF8.GetBytes(canonical));
var witnessHash = $"blake3:{Convert.ToHexString(hash.AsSpan()).ToLowerInvariant()}";
```
---
## DSSE Signing
Witnesses are signed using [DSSE (Dead Simple Signing Envelope)](https://github.com/secure-systems-lab/dsse):
```json
{
"payloadType": "application/vnd.stellaops.witness.v1+json",
"payload": "<base64url-encoded witness JSON>",
"signatures": [
{
"keyid": "sha256:abcd1234...",
"sig": "<base64url-encoded signature>"
}
]
}
```
### Verification
1. Decode the payload from base64url
2. Parse as PathWitness JSON
3. Recompute witness_hash and compare
4. Verify signature against known public key
5. Optionally check transparency log for inclusion
---
## Storage
Witnesses are stored in `scanner.witnesses` table:
| Column | Type | Description |

## Unblock Task Notes (T6a/T6b)
### T6a: Freeze offline checkpoint/receipt contract
- **Goal:** define the canonical offline inputs required to verify inclusion proofs without network access.
- **Use these docs as the baseline (do not invent new shapes):**
- `docs/product-advisories/14-Dec-2025 - Rekor Integration Technical Reference.md` (§13)
- `docs/product-advisories/14-Dec-2025 - Offline and Air-Gap Technical Reference.md` (§3–4; `evidence/tlog/checkpoint.sig` + `entries/`)
- **Minimum deliverables:**
- A single canonical contract doc (new or existing) that answers:
- Where the **tlog public key** comes from (file path, rotation/versioning)
- Where the **signed checkpoint/tree head** lives (file path; signature format)
- Where the **inclusion proof pack** lives (file path; entry + hashes; deterministic ordering rules)
- How the checkpoint is bound to the proof pack (tree size, root hash)
- A schema file (JSON Schema) for the on-disk checkpoint/receipt shape used by Attestor offline verification.
### T6b: Offline fixtures + validation harness
- **Goal:** make offline mode testable and reproducible.
- **Minimum deliverables:**
- Deterministic fixtures committed under `src/Attestor/StellaOps.Attestor.Tests/Fixtures/` (checkpoint, pubkey, valid/invalid proof material).
- Tests that verify:
- checkpoint signature verification succeeds/fails as expected
- recomputed Merkle root matches checkpoint for valid entries and fails for tampered fixtures
- no network calls are required for offline mode

@@ -285,6 +313,7 @@ public Counter<long> CheckpointVerifyTotal { get; } // attestor.checkpoint_
## Interlocks
- Rekor public key distribution must be configured via `AttestorOptions` and documented for offline bundles.
- Offline checkpoints must be pre-distributed; `AllowOfflineWithoutSignature` policy requires explicit operator intent.
- T6a/T6b define the concrete offline checkpoint/receipt contract and fixtures; do not implement T8 until those are published and reviewed.

### EPSS-3410-013A: Perf Harness + Deterministic Dataset Generator
**Description**: Add an offline-friendly perf harness for EPSS ingest without committing a huge static dataset.
**Deliverables**:
- New test project: `src/Scanner/__Tests/StellaOps.Scanner.Storage.Performance.Tests/`
- Deterministic generator: 310k rows with fixed seed, stable row order, and controlled CVE distribution.
- Test tagged so it does not run in default CI (`[Trait("Category","Performance")]` or equivalent).
- Local run snippet (exact `dotnet test` invocation + required env vars for Testcontainers).
**Acceptance Criteria**:
- [ ] Generator produces identical output across runs (same seed ⇒ same SHA-256 of CSV bytes)
- [ ] Perf test runs locally in <= 5 minutes on a dev machine (budget validation happens in CI)
- [ ] No network required beyond local Docker engine for Testcontainers
---
### EPSS-3410-013B: CI Perf Runner + Workflow
**Description**: Enable deterministic perf execution in CI with known hardware + reproducible logs.
**Deliverables**:
- Gitea workflow (nightly + manual): `.gitea/workflows/epss-perf.yml`
- Runner requirements documented (label, OS/arch, CPU/RAM, Docker/Testcontainers support).
- Artifacts retained: perf logs + environment metadata (CPU model, cores, memory, Docker version, image digests).
**Acceptance Criteria**:
- [ ] CI job can spin up PostgreSQL via Testcontainers reliably
- [ ] Perf test output includes total duration + phase breakdowns (parse/insert/changes/current)
- [ ] Budgets enforced only in this workflow (does not break default PR CI)

## Unblock Task Notes (NUC-003A/NUC-003B)
### NUC-003A: Project reference + dependency direction
- **Goal:** make the integration unambiguous: Scanner Worker emits Unknowns during scan; Unknowns.Core provides the domain + classifier.
- **Touchpoints (expected):**
- `src/Scanner/StellaOps.Scanner.Worker/StellaOps.Scanner.Worker.csproj` (add project reference)
- If persistence from Worker is required, also reference `src/Unknowns/__Libraries/StellaOps.Unknowns.Storage.Postgres/` and ensure migrations are applied by Scanner startup.
- **Acceptance criteria (minimum):**
- `dotnet build src/Scanner/StellaOps.Scanner.Worker/StellaOps.Scanner.Worker.csproj` succeeds with no circular references.
### NUC-003B: Wiring from native analyzer to Unknowns
- **Goal:** convert analyzer-side identification/resolution gaps into first-class Unknowns records.
- **Touchpoints (expected):**
- `src/Scanner/StellaOps.Scanner.Analyzers.Native/` (where classification context is produced)

## Unblock Task Notes (WIT-007A..WIT-007D)
### WIT-007A: ReachabilityAnalyzer → witness output contract
- **Goal:** define the exact path output shape (entrypoint → sink), including stable ordering and caps (max depth/path count) so witness generation is deterministic.
- **Touchpoints (expected):** `src/Scanner/__Libraries/StellaOps.Scanner.CallGraph/Analysis/ReachabilityAnalyzer.cs` and `src/Scanner/__Tests/StellaOps.Scanner.CallGraph.Tests/` (fixtures + determinism assertions).
- **Evidence:** fixture graphs + expected path lists committed and validated by tests.
### WIT-007B: ReachabilityAnalyzer refactor (sink-aware + path export)
- **Acceptance criteria (minimum):** analyzer accepts explicit sinks and returns deterministic path(s) per reachable sink without breaking existing tests/behaviour.
### WIT-007C: Witness predicate + DSSE payloadType constants
- **Goal:** remove ambiguity about predicate URI/media type; Scanner/Attestor must sign/verify the same bytes.
- **Touchpoints (expected):** `src/Attestor/StellaOps.Attestor/Predicates/` and `docs/contracts/witness-v1.md`.
### WIT-007D: DSSE signing + verification for witnesses
- **Preferred implementation:** use `src/Attestor/StellaOps.Attestor.Envelope/` (serializer + `EnvelopeSignatureService`) for Ed25519 first.
- **Evidence:** golden fixture payload + DSSE envelope + public key, plus unit tests proving deterministic serialization and successful verification.

- [x] Backfill tool (last 180 days)
- [x] Ops runbook: schedules, manual re-run, air-gap import
---
## 10. Anti-Patterns to Avoid
## 10. Operations Runbook
### 10.1 Configuration
EPSS ingestion is configured via the `Epss:Ingest` section in Scanner Worker configuration:
```yaml
Epss:
Ingest:
Enabled: true # Enable/disable the job
Schedule: "0 5 0 * * *" # Cron expression (default: 00:05 UTC daily)
SourceType: "online" # "online" or "bundle"
BundlePath: null # Path for air-gapped bundle import
InitialDelay: "00:00:30" # Wait before first run (30s)
RetryDelay: "00:05:00" # Delay between retries (5m)
MaxRetries: 3 # Maximum retry attempts
```
### 10.2 Online Mode (Connected)
The job automatically fetches EPSS data from FIRST.org at the scheduled time:
1. Downloads `https://epss.empiricalsecurity.com/epss_scores-YYYY-MM-DD.csv.gz`
2. Validates SHA256 hash
3. Parses CSV and bulk inserts to `epss_scores`
4. Computes delta against `epss_current`
5. Updates `epss_current` projection
6. Publishes `epss.updated` event
### 10.3 Air-Gap Mode (Bundle)
For offline deployments:
1. Download EPSS CSV from FIRST.org on an internet-connected system
2. Copy to the configured `BundlePath` location
3. Set `SourceType: "bundle"` in configuration
4. The job will read from the local file instead of fetching online
### 10.4 Manual Ingestion
Trigger manual ingestion via the Scanner Worker API:
```bash
# POST to trigger immediate ingestion for a specific date
curl -X POST "https://scanner-worker/epss/ingest?date=2025-12-18"
```
### 10.5 Troubleshooting
| Symptom | Likely Cause | Resolution |
|---------|--------------|------------|
| Job not running | `Enabled: false` | Set `Enabled: true` |
| Download fails | Network/firewall | Check HTTPS egress to `epss.empiricalsecurity.com` |
| Parse errors | Corrupted file | Re-download, check SHA256 |
| Slow ingestion | Large dataset | Normal for ~250k rows; expect 60-90s |
| Duplicate runs | Idempotent | Safe - existing data preserved |
### 10.6 Monitoring
Key metrics and traces:
- **Activity**: `StellaOps.Scanner.EpssIngest` with tags:
- `epss.model_date`: Date of EPSS model
- `epss.row_count`: Number of rows ingested
- `epss.cve_count`: Distinct CVEs processed
- `epss.duration_ms`: Total ingestion time
- **Logs**: Structured logs at Info/Warning/Error levels
- `EPSS ingest job started`
- `Starting EPSS ingestion for {ModelDate}`
- `EPSS ingestion completed: modelDate={ModelDate}, rows={RowCount}...`
