Key Decisions

1. Inline Authorization ✅

• Decision: Validate pushes in HTTP handler (not Git hooks)
• Why: Better UX, simpler deployment, easier testing
• Impact: Superior architecture to reference implementation

2. Technology Stack ✅

• actix-web for HTTP server
• git-http-backend for Git protocol
• nostr-relay-builder for Nostr relay
• tokio for async runtime

3. GRASP Compliance Testing Tool ⭐ NEW

• Standalone Rust crate that can test ANY GRASP implementation
• Spec-mirrored structure: Tests match protocol documents exactly
• Clear failures: Cite exact spec lines (e.g., "GRASP-01:12-13")
• Reusable: Can be published for other implementations

Test Strategy Highlights

Spec-Mirrored Tests

/// MUST reject announcements that do not list the service
/// in both `clone` and `relays` tags
///
/// Spec: GRASP-01, Line 12-13
async fn test_rejects_unlisted_announcements(ctx: &TestContext) {
    // Test implementation
}

Clear Failure Reporting

✗ rejects_unlisted_announcements (GRASP-01:12-13)
  Requirement: MUST reject announcements not listing 
               service in clone and relays
  Error: Expected rejection but got acceptance
  Duration: 45ms

Multiple Test Levels

• Unit Tests (~40%): Individual functions
• Integration Tests (~30%): Component interaction
• Compliance Tests (~20%): GRASP spec validation
• End-to-End Tests (~10%): Real Git client workflows

Reusable Compliance Tool

# Test ngit-grasp
cargo test --test compliance

# Test another GRASP implementation
grasp-compliance-tests --url http://other-server.com

# CI/CD integration
- name: GRASP Compliance
  run: cargo test --test compliance

Implementation Estimate

• Lines of Code: ~1,400 (similar to reference)
• Time to MVP: 4-6 weeks (GRASP-01)
• Test Coverage: >80% target
• Compliance: 100% GRASP-01 requirements tested

GRASP Compliance

GRASP-01 (Core Service Requirements)

• ✅ Architecture designed
• ✅ Tests designed (all requirements covered)
• ⏭️ Implementation ready to start

GRASP-02 (Proactive Sync)

• ✅ Architecture designed
• ✅ Test structure ready
• ⏭️ Future phase

GRASP-05 (Archive)

• ✅ Architecture designed
• ✅ Test structure ready
• ⏭️ Future phase

Benefits of Compliance Testing Tool

For ngit-grasp

• Validate implementation against spec
• Continuous compliance in CI/CD
• Clear error messages for violations

For Other Implementations

• Reusable test suite for any GRASP server
• Language-agnostic (tests over HTTP/WebSocket)
• Standardized compliance validation

For GRASP Protocol

• Reference test suite for specification
• Helps clarify ambiguous requirements
• Evolves with spec versions

Recommendation

✅ PROCEED WITH IMPLEMENTATION

The architecture is:

• ✅ Technically sound
• ✅ Pragmatic and achievable
• ✅ Superior to hook-based approach
• ✅ Comprehensively documented
• ✅ Fully testable with compliance tool
• ✅ GRASP-compliant

Next Steps

1. Review documentation (start with REVIEW_SUMMARY.md)
2. Review test strategy (docs/TEST_STRATEGY.md)
3. Provide feedback or approve architecture
4. Begin implementation following docs/GETTING_STARTED.md
5. Build compliance tool as first step (validates as we build)
