## Summary
This commit completes Phase 2 of the configuration-driven crypto architecture, achieving
100% crypto compliance by eliminating all hardcoded cryptographic implementations.
## Key Changes
### Phase 1: Plugin Loader Infrastructure

### Phase 2: Code Refactoring
- **API Extension**: Added ICryptoProvider.CreateEphemeralVerifier for verification-only scenarios
- **Plugin Implementation**: Created OfflineVerificationCryptoProvider with ephemeral verifier support
- Supports ES256/384/512, RS256/384/512, PS256/384/512
- SubjectPublicKeyInfo (SPKI) public key format
- **100% Compliance**: Refactored DsseVerifier to remove all BouncyCastle cryptographic usage
- **Unit Tests**: Created OfflineVerificationProviderTests with 39 passing tests
- **Documentation**: Created comprehensive security guide at docs/security/offline-verification-crypto-provider.md
- **Audit Infrastructure**: Created scripts/audit-crypto-usage.ps1 for static analysis
### Testing Infrastructure (TestKit)
- **Determinism Gate**: Created DeterminismGate for reproducibility validation
- **Test Fixtures**: Added PostgresFixture and ValkeyFixture using Testcontainers
- **Traits System**: Implemented test lane attributes for parallel CI execution
- **JSON Assertions**: Added CanonicalJsonAssert for deterministic JSON comparisons
- **Test Lanes**: Created test-lanes.yml workflow for parallel test execution
### Documentation
- **Architecture**: Created CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md master plan
- **Sprint Tracking**: Created SPRINT_1000_0007_0002_crypto_refactoring.md (COMPLETE)
- **API Documentation**: Updated docs2/cli/crypto-plugins.md and crypto.md
- **Testing Strategy**: Created testing strategy documents in docs/implplan/SPRINT_5100_0007_*
## Compliance & Testing
- ✅ Zero direct System.Security.Cryptography usage in production code
- ✅ All crypto operations go through ICryptoProvider abstraction
- ✅ 39/39 unit tests passing for OfflineVerificationCryptoProvider
- ✅ Build successful (AirGap, Crypto plugin, DI infrastructure)
- ✅ Audit script validates crypto boundaries
## Files Modified
**Core Crypto Infrastructure:**
- src/__Libraries/StellaOps.Cryptography/CryptoProvider.cs (API extension)
- src/__Libraries/StellaOps.Cryptography/CryptoSigningKey.cs (verification-only constructor)

**Plugin Implementation:**
- src/__Libraries/StellaOps.Cryptography.Plugin.OfflineVerification/ (new)
- src/__Libraries/StellaOps.Cryptography.PluginLoader/ (new)
**Production Code Refactoring:**

**Tests:**
- src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests/ (new, 39 tests)
- src/__Libraries/__Tests/StellaOps.Cryptography.PluginLoader.Tests/ (new)
**Configuration:**
- etc/crypto-plugins-manifest.json (plugin registry)
- etc/appsettings.crypto.*.yaml (regional profiles)
**Documentation:**
- docs/security/offline-verification-crypto-provider.md (600+ lines)
- docs/implplan/CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md (master plan)
- docs/implplan/SPRINT_1000_0007_0002_crypto_refactoring.md (Phase 2 complete)
## Next Steps
Phase 3: Docker & CI/CD Integration
- Create multi-stage Dockerfiles with all plugins
- Build regional Docker Compose files
- Implement runtime configuration selection
- Add deployment validation scripts

Findings workspace
Purpose
- Present materialized policy verdicts with explainability, filtering, and export support.
- Preserve aggregation-only provenance while enabling triage and automation.
Access and dependencies
- Route: /console/findings with optional panel=explain.
- Scopes: findings.read, policy:runs, policy:simulate, downloads.read.
- Depends on Policy Engine effective findings, Concelier and Excititor provenance, SBOM service metadata.
- Feature flags: findings.explain.enabled, findings.savedViews.enabled, findings.simulationDiff.enabled.
Layout
- Header with tenant badge, policy selector, global filters, and actions.
- Summary cards: affected assets, critical count, KEV count.
- Findings grid (virtualized) with right-side drawer for details.
Filters and saved views
- Status: affected, at_risk, quieted, fixed, not_applicable, mitigated.
- Severity: critical, high, medium, low, informational, untriaged.
- KEV toggle and exploitability hints.
- Policy view: active, staged, simulation.
- Component search by PURL or substring.
- SBOM filter by image digest or SBOM ID.
- Tags from policy outputs.
- Run window and explain hints (rule ID, justification, VEX provider).
- Saved views persist per tenant and policy; shared views appear in the rail.
Grid columns and badges
- Status badge with rationale and quieted expiry.
- Severity with score tooltip.
- Component PURL and SBOM link.
- Policy name and revision digest.
- Source signals (VEX, advisory, runtime overlays).
- Age since last evaluation.
- Row badges: KEV, override, simulation only, determinism alert.
Bulk actions
- Open explains (batch drawer).
- Export CSV or JSON.
- Copy CLI batch explain commands.
- Create ticket using configured integrations.
Explain drawer
- Summary: status, severity, policy decision, rule ID, run ID, SBOM link.
- Rule chain: ordered rule hits with actions and score contributions.
- Evidence: advisory, VEX, runtime signals, overrides.
- VEX impact: claims used, justification, acceptance.
- History: state transitions with timestamps and operators.
- Raw trace: canonical policy trace with CLI parity.
Simulations and comparisons
- Compare active vs staged or simulation snapshots with diff banners.
- Side-by-side view highlights added, removed, and severity changes.
- Simulation results expire after a retention window and prompt re-run.
Exports and automation
- Immediate CSV, JSON, and Markdown summary exports.
- Scheduled exports produce full tenant reports with manifests.
- Explain bundle export packages traces for audit.
- Webhook subscription hints for export completion.
Real-time updates
- SSE stream updates new findings, status changes, and quieted expirations.
- Metrics cards mirror findings_critical_total, findings_quieted_total, findings_kev_total.
- Errors surface correlation IDs for logs.
Offline behavior
- Snapshot banner shows offline dataset and staleness.
- Explain drawer notes cached evidence sources.
- Exports default to local paths with transfer guidance.
- Tenants missing in the snapshot are hidden.
