## Quick Start Commands

### Full Pipeline Execution
```bash
# Complete pipeline (3-5 minutes)
./harness/local-ci-pipeline.sh

# Fast validation (30-60 seconds)
HARNESS_SKIP_DOCKER=true HARNESS_SKIP_MATH_AUDIT=true HARNESS_SKIP_SECURITY=true ./harness/local-ci-pipeline.sh

# Pre-commit check
make build && make test
```

### Individual Components
```bash
# Build and test
make build test

# Security and quality
go vet ./... && golangci-lint run

# Coverage report
go test -coverprofile=coverage.out ./... && go tool cover -html=coverage.out

# Math audit
make math-audit

# Docker build
docker build -t mev-bot:test .
```

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

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

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

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

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

### ✅ Specialized Tools
```bash
# 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
```

## Configuration Options

### Environment Variables
```bash
# Harness control
HARNESS_SKIP_DOCKER=true      # Skip container builds
HARNESS_SKIP_MATH_AUDIT=true  # Skip mathematical validation
HARNESS_SKIP_SECURITY=true    # Skip security scans
HARNESS_PARALLEL_JOBS=4       # Concurrent execution

# Paths
HARNESS_LOG_DIR=./harness/logs
HARNESS_REPORT_DIR=./harness/reports
HARNESS_GOCACHE=./.gocache
```

### Runtime Selection
```bash
# Auto-detected in order: podman, docker
HARNESS_RUNTIME=podman ./harness/local-ci-pipeline.sh
HARNESS_RUNTIME=docker ./harness/local-ci-pipeline.sh
```
