feat: add Attestation Chain and Triage Evidence API clients and models
- Implemented Attestation Chain API client with methods for verifying, fetching, and managing attestation chains. - Created models for Attestation Chain, including DSSE envelope structures and verification results. - Developed Triage Evidence API client for fetching finding evidence, including methods for evidence retrieval by CVE and component. - Added models for Triage Evidence, encapsulating evidence responses, entry points, boundary proofs, and VEX evidence. - Introduced mock implementations for both API clients to facilitate testing and development.

# 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 |
|
||||
|--------|------|-------------|
|
||||
| `witness_id` | UUID | Primary key |
|
||||
| `witness_hash` | TEXT | BLAKE3 hash (unique) |
|
||||
| `payload_json` | JSONB | Full witness JSON |
|
||||
| `dsse_envelope` | JSONB | Signed envelope (nullable) |
|
||||
| `graph_hash` | TEXT | Source graph reference |
|
||||
| `sink_cve` | TEXT | CVE for quick lookup |
|
||||
|
||||
---
|
||||
|
||||
## API Endpoints
|
||||
|
||||
| Method | Path | Description |
|
||||
|--------|------|-------------|
|
||||
| `GET` | `/api/v1/witnesses/{id}` | Get witness by ID |

# Sprint 3104 · Signals callgraph projection completion
|
||||
|
||||
**Status:** DONE
|
||||
**Priority:** P2 - MEDIUM
|
||||
**Module:** Signals
|
||||
**Working directory:** `src/Signals/`
|
||||
|
||||
## Topic & Scope
|
||||
- Pick up the deferred projection/sync work from `docs/implplan/archived/SPRINT_3102_0001_0001_postgres_callgraph_tables.md` so the relational tables created by `src/Signals/StellaOps.Signals.Storage.Postgres/Migrations/V3102_001__callgraph_relational_tables.sql` become actively populated and queryable.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- Depends on Signals Postgres schema migrations already present (relational callgraph tables exist).
|
||||
- Touches both:
|
||||
- `src/Signals/StellaOps.Signals/` (ingest trigger), and
|
||||
- `src/Signals/StellaOps.Signals.Storage.Postgres/` (projection implementation).
|
||||
- Keep changes additive and deterministic; no network I/O.
|
||||
|
||||
## Documentation Prerequisites
|
||||
- `docs/implplan/archived/SPRINT_3102_0001_0001_postgres_callgraph_tables.md`
|
||||
- `src/Signals/StellaOps.Signals.Storage.Postgres/Migrations/V3102_001__callgraph_relational_tables.sql`

||||
| 5 | SIG-CG-3104-005 | DONE | Close bookkeeping | Signals · Storage | Update local `TASKS.md` and sprint status with evidence. |
|
||||
|
||||
## Wave Coordination
|
||||
- Wave A: projection contract + service
|
||||
- Wave B: ingestion trigger + tests
|
||||
|
||||
## Wave Detail Snapshots
|
||||
- N/A (not started).
|
||||
|
||||
## Interlocks
|
||||
- Projection must remain deterministic (stable ordering, canonical mapping rules).
|
||||
- Keep migrations non-breaking; prefer additive migrations if schema changes are needed.

|
||||
|
||||
## Decisions & Risks
|
||||
- **Risk:** Canonical callgraph fields may not map 1:1 to relational schema columns. **Mitigation:** define explicit projection rules and cover with tests.
|
||||
- **Risk:** Large callgraphs may require bulk insert. **Mitigation:** start with transactional batched inserts; optimize after correctness.

## 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}...`
