### Blockers (Policy Engine Integration - Tasks 35-40)
### Resolved: Policy Engine Integration Architecture (Tasks 35-40)
The following architectural issues block Wave 5:
**Resolution Date**: 2025-12-25
1. **Internal class visibility**: `PolicyEvaluator` in `StellaOps.Policy.Engine` is `internal sealed`. Injecting `IProvcacheService` requires either:
- Making it public with a DI-friendly constructor pattern
- Creating a wrapper service layer that orchestrates caching + evaluation
- Adding a caching layer at a higher level (e.g., at the API/orchestration layer)
The architectural blockers have been resolved with the following decisions:
2. **Integration point unclear**: The Policy Engine has multiple evaluation entry points:
- `PolicyEvaluator.Evaluate()` - internal, per-finding evaluation
- `EvaluationOrchestrationWorker` - batch evaluation orchestrator
- `PolicyRuntimeEvaluationService` - used by tests
- Needs architectural decision on which layer owns the cache read/write responsibility
1. **Caching Decorator Pattern**: Create `ProvcachePolicyEvaluationCache` that implements the existing `IPolicyEvaluationCache` interface.
- Follows the established pattern (see `MessagingPolicyEvaluationCache`)
- `PolicyEvaluator` remains `internal sealed` (no change needed)
- Cache decorator is registered in DI via `AddPolicyEngineCore()`
- Integrates with `PolicyRuntimeEvaluationService` at the service layer
3. **VeriKey construction from context**: `PolicyEvaluationContext` contains many inputs, but mapping them to `VeriKeyBuilder` inputs requires:
- Defining canonical serialization for SBOM, VEX statements, advisory metadata
- Ensuring all inputs that affect the decision are included in the VeriKey
- Excluding non-deterministic fields (timestamps, request IDs)
2. **Integration Point Decision**: The caching layer sits at the `IPolicyEvaluationCache` level:
- Cache lookup occurs before `PolicyRuntimeEvaluationService.Evaluate()`
- Cache write occurs after successful evaluation
- This is the same level as existing `MessagingPolicyEvaluationCache`
- Worker and orchestrator services use the cache transparently
**Recommendation**: Create a separate sprint for Policy Engine integration after architectural review with Policy Guild. The Provcache core library is complete and can be used independently.
3. **VeriKey Construction Strategy**:
- Extract canonical inputs from `PolicyEvaluationContext` via extension methods
- Use `VeriKeyBuilder` to compose the key from: source_hash, sbom_hash, vex_hash_set, policy_hash, signer_set_hash
- Time window determined by `ProvcacheOptions.TimeWindowBucket` (default: hourly)
- Non-deterministic fields (timestamps, request IDs) are excluded by design
**Tasks 35-40 are now UNBLOCKED** and can proceed with implementation.

# AGENTS
## Role
---
## Canonical Advisory Service
### Role
Deduplicated canonical advisory management with provenance-scoped source edges. Ingests raw advisories from multiple sources (NVD, GHSA, OSV, vendor, distro), computes merge hashes for deduplication, and maintains canonical records with linked source edges.
### Scope
- **Ingestion**: `IngestAsync` and `IngestBatchAsync` - Raw advisory to canonical pipeline with merge hash computation, duplicate detection, and source edge creation.
- **Query**: `GetByIdAsync`, `GetByCveAsync`, `GetByArtifactAsync`, `GetByMergeHashAsync`, `QueryAsync` - Lookup canonical advisories with source edges.
- **Status**: `UpdateStatusAsync`, `DegradeToStubsAsync` - Lifecycle management (Active, Stub, Withdrawn).
- **Caching**: `CachingCanonicalAdvisoryService` decorator with configurable TTLs for hot queries.
- **Signing**: Optional DSSE signing of source edges via `ISourceEdgeSigner` integration.
### Interfaces & Contracts
- **ICanonicalAdvisoryService**: Main service interface for ingest and query operations.
- **ICanonicalAdvisoryStore**: Storage abstraction for canonical/source edge persistence.
- **IMergeHashCalculator**: Merge hash computation (CVE + PURL + version range + CWE + patch lineage).
- **ISourceEdgeSigner**: Optional DSSE envelope signing for source edges.
### Domain Models
- **CanonicalAdvisory**: Deduplicated advisory record with merge hash, status, severity, EPSS, weaknesses.
- **SourceEdge**: Link from source advisory to canonical with precedence rank, doc hash, DSSE envelope.
- **IngestResult**: Outcome with MergeDecision (Created, Merged, Duplicate, Conflict).
- **RawAdvisory**: Input from connectors with CVE, affects key, version range, weaknesses.
### Source Precedence
Lower rank = higher priority for metadata updates:
- `vendor` = 10 (authoritative)
- `redhat/debian/suse/ubuntu/alpine` = 20 (distro)
- `osv` = 30
- `ghsa` = 35
- `nvd` = 40 (fallback)
### API Endpoints
- `GET /api/v1/canonical/{id}` - Get by ID
- `GET /api/v1/canonical?cve={cve}&artifact={purl}&mergeHash={hash}` - Query
- `POST /api/v1/canonical/ingest/{source}` - Ingest single advisory
- `POST /api/v1/canonical/ingest/{source}/batch` - Batch ingest
- `PATCH /api/v1/canonical/{id}/status` - Update status
### In/Out of Scope
**In**: Merge hash computation, canonical upsert, source edge linking, duplicate detection, caching, DSSE signing.
**Out**: Raw advisory fetching (connectors), database schema (Storage.Postgres), HTTP routing (WebService).
### Observability
- Logs: canonical ID, merge hash, decision, source, precedence rank, signing status.
- Cache: hit/miss tracing at Trace level.
### Tests
- Unit tests in `Core.Tests/Canonical/` covering ingest pipeline, caching, signing.
- Integration tests in `WebService.Tests/Canonical/` for API endpoints.
---
## Job Orchestration
### Role
Job orchestration and lifecycle. Registers job definitions, schedules execution, triggers runs, reports status for connectors and exporters.
## Scope
### Scope
- Contracts: IJob (execute with CancellationToken), JobRunStatus, JobTriggerOutcome/Result.
- Registration: JobSchedulerBuilder.AddJob<T>(kind, cronExpression?, timeout?, leaseDuration?); options recorded in JobSchedulerOptions.
- Plugin host integration discovers IJob providers via registered IDependencyInjectionRoutine implementations.

The registry exposed via `AliasSchemes` and `AliasSchemeRegistry` can be used to validate aliases and

## Merge Hash
The merge hash is a deterministic semantic identity hash that enables provenance-scoped deduplication.
Unlike content hashing (which changes when any field changes), merge hash is computed from identity
components only, allowing the same CVE from different sources (Debian, RHEL, NVD, etc.) to produce
identical hashes when semantically equivalent.
### Purpose
- **Deduplication**: Identify equivalent advisories across multiple sources
- **Stable Identity**: Hash remains constant despite variations in non-identity fields (title, description, CVSS scores)
- **Source Independence**: Same CVE affecting the same package produces the same hash regardless of source
### Hash Format
The merge hash is a hex-encoded SHA256 hash prefixed with `sha256:`:
```
sha256:a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2
```
Total length: 71 characters (`sha256:` prefix + 64 hex characters).
### Identity Components
The merge hash is computed from the following canonical string format:
```
CVE:{cve}|AFFECTS:{affects_key}|VERSION:{version_range}|CWE:{cwes}|LINEAGE:{patch_lineage}
```
| Component | Source | Notes |
|-----------|--------|-------|
| `cve` | Advisory key or CVE alias | Normalized to uppercase (e.g., `CVE-2024-1234`) |
| `affects_key` | First affected package identifier | PURL or CPE, normalized to canonical form |
| `version_range` | First affected package version ranges | Canonical interval notation, sorted |
| `cwes` | Advisory weaknesses | Uppercase, sorted numerically, comma-joined |
| `patch_lineage` | Patch references | Extracted commit SHA or PATCH-ID (optional) |
### Normalization Rules
#### CVE Normalization
- Uppercase: `cve-2024-1234` → `CVE-2024-1234`
- Numeric-only input prefixed: `2024-1234` → `CVE-2024-1234`
- Non-CVE advisories use advisory key as-is
#### PURL Normalization
- Type lowercase: `pkg:NPM/lodash` → `pkg:npm/lodash`
- Namespace/name lowercase: `pkg:npm/LODASH` → `pkg:npm/lodash`
- Strip non-identity qualifiers: `?arch=amd64`, `?checksum=...`, `?platform=linux`
- Preserve version: `@4.17.0` retained
#### CPE Normalization
- Convert CPE 2.2 to 2.3: `cpe:/a:vendor:product:1.0` → `cpe:2.3:a:vendor:product:1.0:*:*:*:*:*:*:*`
- Lowercase all components
- Normalize wildcards: `ANY` → `*`, `NA` → `-`
#### Version Range Normalization
- Interval to comparison: `[1.0.0, 2.0.0)` → `>=1.0.0,<2.0.0`
- Trim whitespace: `< 1.5.0` → `<1.5.0`
- Fixed notation: `fixed: 1.5.1` → `>=1.5.1`
- Multiple constraints sorted and comma-joined
#### CWE Normalization
- Uppercase: `cwe-79` → `CWE-79`
- Sort numerically: `CWE-89,CWE-79` → `CWE-79,CWE-89`
- Deduplicate
- Comma-joined output
#### Patch Lineage Normalization
- Extract 40-character SHA from GitHub/GitLab URLs
- Extract SHA from `commit {sha}` or `backport of {sha}` patterns
- Normalize PATCH-ID to uppercase: `patch-12345` → `PATCH-12345`
- Returns `null` for unrecognized formats (produces empty string in canonical form)
### Multi-Package Advisories
When an advisory affects multiple packages, the merge hash is computed from the first affected package.
Use `ComputeMergeHash(advisory, affectedPackage)` to compute per-package hashes for deduplication
at the package level.
### Implementation
The merge hash is computed by `MergeHashCalculator` in `StellaOps.Concelier.Merge.Identity`:
```csharp
var calculator = new MergeHashCalculator();
var hash = calculator.ComputeMergeHash(advisory);
// or for specific package:
var packageHash = calculator.ComputeMergeHash(advisory, affectedPackage);
```
### Migration
During migration, the `mergeHash` field is nullable. Use `MergeHashShadowWriteService` to backfill
hashes for existing advisories:
```csharp
var shadowWriter = new MergeHashShadowWriteService(advisoryStore, calculator, logger);
var result = await shadowWriter.BackfillAllAsync(cancellationToken);
// result.Updated: count of advisories updated with merge hashes
```
