# Scanner Module — Score Proofs & Reachability Implementation Guide
|
||||
|
||||
**Module**: Scanner (Scanner.WebService + Scanner.Worker)
|
||||
**Sprint**: SPRINT_3500_0002_0001 through SPRINT_3500_0004_0004
|
||||
**Target**: Agents implementing deterministic score proofs and binary reachability
|
||||
|
||||
---
|
||||
|
||||
## Purpose
|
||||
|
||||
This guide provides step-by-step implementation instructions for agents working on:
|
||||
1. **Epic A**: Deterministic Score Proofs + Unknowns Registry
|
||||
2. **Epic B**: Binary Reachability v1 (.NET + Java)
|
||||
|
||||
**Role**: You are an implementer agent. Your job is to write code, tests, and migrations following the specifications in the sprint files. Do NOT make architectural decisions or ask clarifying questions—if ambiguity exists, mark the task as BLOCKED in the delivery tracker.

||||
}
|
||||
```
|

|
||||
- Seed BFS from entrypoints
|
||||
- Traverse graph (bounded depth: 100 hops)
|
||||
- Track visited nodes and paths
|
||||
- Map reachable nodes to PURLs via `symbol_component_map`
|
||||
- For each vulnerability:
|
||||
- Check if affected PURL's symbols are reachable
|
||||
- Assign status: `REACHABLE_STATIC`, `UNREACHABLE`, `POSSIBLY_REACHABLE`
|
||||
- Compute confidence score
|
||||
3. Output `ReachabilityFinding[]`
|
||||
|
||||

|
||||
{
|

## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
**Coverage Target**: ≥85% for all new code
|
||||
|
||||
**Key Test Suites**:
|
||||
- `CanonJsonTests` — JSON canonicalization
|
||||
- `DsseEnvelopeTests` — Signature verification
|
||||
- `ProofLedgerTests` — Node hashing, root hash
|
||||
- `ScanManifestTests` — Manifest hash computation
|
||||
- `ProofBundleWriterTests` — Bundle creation
|
||||
- `DotNetCallGraphExtractorTests` — Call-graph extraction
|
||||
- `ReachabilityAnalyzerTests` — BFS algorithm
|
||||
|
||||
**Running Tests**:
|
||||
|
||||
```bash
|
||||
cd src/Scanner
|
||||
dotnet test --filter "Category=Unit"
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
**Location**: `src/__Tests/StellaOps.Integration.Tests/`
|
||||
|
||||
**Required Scenarios**:
|
||||
1. Full pipeline: Scan → Manifest → Proof Bundle → Replay
|
||||
2. Call-graph → Reachability → Findings
|
||||
3. API endpoints: POST /scans → GET /manifest → POST /score/replay
|
||||
|
||||
**Setup**:
|
||||
- Use Testcontainers for Postgres
|
||||
- Seed database with migrations
|
||||
- Use in-memory DSSE signer for tests
|
||||
|
||||
**Running Integration Tests**:
|
||||
|
||||
```bash
|
||||
dotnet test --filter "Category=Integration"
|
||||
```
|
||||
|
||||
### Golden Corpus Tests
|
||||
|
||||
**Location**: `/offline/corpus/ground-truth-v1/`
|
||||
|
||||
**Test Cases**:
|
||||
1. ASP.NET controller → reachable vuln
|
||||
2. Vulnerable lib never called → unreachable
|
||||
3. Reflection-based activation → possibly_reachable
|
||||
|
||||
**Format**:
|
||||
|
||||
```
|
||||
corpus/
|
||||
├── 001_reachable_vuln/
|
||||
│ ├── app.sln
|
||||
│ ├── expected.json # Expected reachability verdict
|
||||
│ └── README.md
|
||||
├── 002_unreachable_vuln/
|
||||
└── ...
|
||||
```
|
||||
|
||||
**Running Corpus Tests**:
|
||||
|
||||
```bash
|
||||
stella test corpus --path /offline/corpus/ground-truth-v1/
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Debugging Tips
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Issue**: Canonical JSON hashes don't match across runs
|
||||
|
||||
**Solution**:
|
||||
- Check for floating-point precision differences
|
||||
- Verify no environment variables in serialization
|
||||
- Ensure stable key ordering (Ordinal comparison)
|
||||
|
||||
**Issue**: DSSE signature verification fails
|
||||
|
||||
**Solution**:
|
||||
- Check PAE encoding matches spec
|
||||
- Verify same key used for sign and verify
|
||||
- Inspect base64 encoding/decoding
|
||||
|
||||
**Issue**: Reachability BFS misses paths
|
||||
|
||||
**Solution**:
|
||||
- Verify adjacency list built correctly
|
||||
- Check max depth limit (100 hops)
|
||||
- Inspect edge filtering (`kind='static'` only)
|
||||
|
||||
**Issue**: EF Core migration fails
|
||||
|
||||
**Solution**:
|
||||
- Check advisory lock acquired
|
||||
- Verify no concurrent migrations
|
||||
- Inspect Postgres logs for errors
|
||||
