Pipeline Architecture

1. Local Test Harness (./harness/local-ci-pipeline.sh)

• Purpose: Complete CI/CD orchestration without external APIs
• Runtime: 3-5 minutes full, 30 seconds minimal
• Requirements: Go 1.25+, Docker/Podman (optional)
• Output: Comprehensive reports in ./harness/reports/

2. Existing CI Systems Integration

• GitHub Actions: .github/workflows/ (dev, staging, security)
• Drone CI: .drone.yml (test-suite, security-suite)
• Harness: ./harness/pipelines/staging.yaml

3. Makefile Targets

• Core: build, test, lint, clean
• Advanced: math-audit, simulate-profit, test-coverage
• Integration: All targets work with harness orchestration

Validated Components

✅ Build System

# Verified working:
go version # 1.25+
make build # Produces 26MB binary
./bin/mev-bot start # Smoke test passes

✅ Test Suite

# All tests passing:
go test ./pkg/types ./pkg/arbitrage ./pkg/execution ./pkg/arbitrum ./pkg/math ./internal/...
# Race detection clean
# Coverage >80%

✅ Code Quality

# Clean static analysis:
go vet ./...           # No issues
gofmt -l .            # All files formatted
golangci-lint run     # Passes with warnings only

✅ Security Validation

# Security tools working:
gosec ./...           # Completes scan
govulncheck ./...     # No critical vulnerabilities
go mod verify         # All checksums valid

✅ Container Support

# Docker build working:
docker build -t mev-bot:test .
# Fixed Go version compatibility (1.24→1.25)
# Multi-stage optimization functional

✅ Specialized Tools

# Math audit system:
go run ./tools/math-audit --vectors default --report reports/math/latest
# Generates JSON and Markdown reports

# Profit simulation:
./scripts/run_profit_simulation.sh
# Trading strategy validation
