master dac8e10e36 feat(crypto): Complete Phase 2 - Configuration-driven crypto architecture with 100% compliance
## 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
- **Plugin Discovery System**: Created StellaOps.Cryptography.PluginLoader with manifest-based loading
- **Configuration Model**: Added CryptoPluginConfiguration with regional profiles support
- **Dependency Injection**: Extended DI to support plugin-based crypto provider registration
- **Regional Configs**: Created appsettings.crypto.{international,russia,eu,china}.yaml
- **CI Workflow**: Added .gitea/workflows/crypto-compliance.yml for audit enforcement

### 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)
- src/__Libraries/StellaOps.Cryptography/EcdsaSigner.cs (fixed ephemeral verifier)

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

**Production Code Refactoring:**
- src/AirGap/StellaOps.AirGap.Importer/Validation/DsseVerifier.cs (100% compliant)

**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

Regulator-grade threat and evidence model

This summary captures the regulator-facing threat and evidence model for the platform without project-specific schedules or delivery notes.

Threat model goals

  • Preserve decision integrity, evidence integrity, confidentiality, and availability across online and air-gapped deployments.
  • Ensure non-repudiation for approvals and decisions.
  • Keep evidence replayable and deterministic.

Evidence principles

  • Integrity: content-addressed and immutable storage.
  • Authenticity: signed artifacts and verified trust roots.
  • Traceability: decisions link to all inputs and transformations.
  • Reproducibility: decisions are replayable with frozen inputs.
  • Confidentiality: redaction profiles and scoped access.
  • Known unknowns are captured explicitly.

Evidence taxonomy (high level)

  • Input artifacts: SBOM, VEX, provenance, scan outputs.
  • Normalization artifacts: identity resolution and mapping logs.
  • Analysis artifacts: reachability, diffs, scoring traces.
  • Governance artifacts: policies, approvals, exceptions.
  • Decision artifacts: verdicts, explanations, signatures.

Controls and audit expectations

  • Strong auth and scoped tokens for ingestion and admin flows.
  • Signed manifests and optional transparency anchors.
  • Rate limiting and size guards for ingestion DoS protection.
  • Least privilege and separation of duties for policy changes.
  • Audit packages with hashes, signatures, and policy versions.

Offline and export

  • Offline bundles carry signed manifests and dataset snapshots.
  • Exports include redaction profiles and integrity metadata.
