Subject: [PATCH] ci: add comprehensive CI/CD pipeline with 100% coverage
 enforcement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Created complete CI/CD infrastructure for V2 development:

GitHub Actions Pipeline (.github/workflows/v2-ci.yml):
- Pre-flight checks (branch naming, commit messages)
- Build & dependency validation
- Code quality with 40+ linters (golangci-lint)
- Unit tests with MANDATORY 100% coverage enforcement
- Integration tests with timeout management
- Performance benchmarks (parser < 5ms, detection < 10ms, e2e < 50ms)
- Decimal precision validation
- Modularity validation (component independence)
- Final validation summary with PR comments

Code Quality (.golangci.yml):
- 40+ enabled linters for comprehensive checks
- Cyclomatic complexity limits (max 15)
- Magic number detection
- Security scanning (gosec)
- Style checking with MEV/DEX terminology
- Test file exclusions for appropriate linters

Build Automation (Makefile):
- build, test, test-coverage with 100% enforcement
- lint, fmt, vet, security targets
- deps-download, deps-verify, deps-tidy, deps-check
- validate (full CI/CD locally)
- bench (performance benchmarks)
- check-modularity, check-circular
- Color-coded output for better UX

Git Optimization (.gitattributes):
- LF normalization for cross-platform consistency
- Binary file handling
- Diff settings for Go files
- Merge strategies
- Export-ignore for archives

Git Hooks (.git-hooks/):
- pre-commit: format, tests, vet, secret detection, go.mod tidy
- commit-msg: message format validation
- README with installation instructions
- install-git-hooks.sh script for easy setup

Documentation (docs/planning/05_CI_CD_SETUP.md):
- Complete pipeline architecture diagram
- Local development workflow
- GitHub Actions job descriptions
- Performance optimizations (caching, parallel execution)
- Failure handling and debugging
- Branch protection rules
- Deployment process
- Best practices and troubleshooting

Performance Targets:
- Pipeline duration: < 15 minutes
- Test coverage: 100% (enforced, non-negotiable)
- Parser latency: < 5ms
- Arbitrage detection: < 10ms
- End-to-end: < 50ms

+# Git Hooks for MEV Bot V2
+
+This directory contains Git hooks to ensure code quality and consistency.
+
+## Installation
+
+Run these commands from the repository root:
+
+```bash
+# Make hooks executable
+chmod +x .git-hooks/*
+
+# Install pre-commit hook
+ln -sf ../../.git-hooks/pre-commit .git/hooks/pre-commit
+
+# Install commit-msg hook
+ln -sf ../../.git-hooks/commit-msg .git/hooks/commit-msg
+```
+
+Or use the provided installation script:
+
+```bash
+./scripts/install-git-hooks.sh
+```
+
+## Available Hooks
+
+### pre-commit
+
+Runs before each commit and performs:
+
+1. **Branch Name Validation** - Ensures correct naming convention
+2. **Merge Conflict Detection** - Prevents committing conflict markers
+3. **Secret Detection** - Scans for passwords, API keys, tokens
+4. **Dependency Management** - Auto-tidies go.mod and go.sum
+5. **Code Formatting** - Auto-formats Go code with gofmt
+6. **Quick Tests** - Runs tests on changed packages
+7. **Go Vet** - Runs static analysis
+8. **File Size Check** - Warns about large files
+
+### commit-msg
+
+Validates commit message format:
+
+**Required Format:**
+```
+type(scope): description
+
+Optional body explaining the change
+
+🤖 Generated with [Claude Code](https://claude.com/claude-code)
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+**Valid Types:**
+- `feat` - New feature
+- `fix` - Bug fix
+- `perf` - Performance improvement
+- `refactor` - Code refactoring
+- `test` - Tests
+- `docs` - Documentation
+- `build` - Build system
+- `ci` - CI/CD
+
+**Example:**
+```
+feat(parsers): add UniswapV2 parser with event validation
+
+- Implements ParseLog() for Swap events
+- Adds token extraction from pool cache
+- Includes comprehensive validation rules
+- Achieves 100% test coverage

+```
+
+## Bypassing Hooks (Emergency Only)
+
+If you absolutely must bypass hooks:
+
+```bash
+git commit --no-verify -m "emergency fix"
+```
+
+**⚠️ Warning:** Only use in emergencies. CI/CD will still enforce all checks.
+
+## Troubleshooting
+
+### Hook not executing
+
+1. Check if hook is executable:
+   ```bash
+   ls -l .git/hooks/pre-commit
+   ```
+
+2. If not, make it executable:
+   ```bash
+   chmod +x .git/hooks/pre-commit
+   ```
+
+### Hook failing unexpectedly
+
+1. Run the hook manually to see errors:
+   ```bash
+   .git/hooks/pre-commit
+   ```
+
+2. Check that all required tools are installed:
+   ```bash
+   which gofmt
+   which go
+   ```
+
+### Disabling hooks temporarily
+
+```bash
+# Disable all hooks
+git config core.hooksPath /dev/null
+
+# Re-enable hooks
+git config --unset core.hooksPath
+```
+
+## Best Practices
+
+1. **Never bypass hooks** unless absolutely necessary
+2. **Fix issues** instead of bypassing
+3. **Keep hooks fast** - they run on every commit
+4. **Test hooks locally** before committing to shared repository
+5. **Document any new hooks** added to this directory
+
+## Performance
+
+Hooks are designed to be fast:
+
+- **Pre-commit**: Typically < 5 seconds
+- **Commit-msg**: < 1 second
+
+If hooks are slow, consider:
+
+1. Only testing changed packages (already implemented)
+2. Using `--short` flag for tests (already implemented)
+3. Running full tests in CI/CD instead
+
+## Maintenance
+
+Review and update hooks periodically:
+
+1. Add new checks as project evolves
+2. Remove obsolete checks
+3. Optimize performance
+4. Keep documentation up to date

+
+## Local Development Workflow
+
+### Git Hooks
+
+#### Pre-Commit Hook
+
+Location: `.git-hooks/pre-commit`
+
+**Checks performed:**
+1. Branch name validation
+2. Merge conflict detection
+3. Secret and forbidden pattern detection
+4. go.mod/go.sum tidiness
+5. Code formatting (auto-fix)
+6. Quick tests on changed packages
+7. go vet static analysis
+8. File size warnings
+
+**Installation:**
+```bash
+./scripts/install-git-hooks.sh
+```
+
+**Manual bypass (emergency only):**
+```bash
+git commit --no-verify
+```
+
+#### Commit-msg Hook
+
+Location: `.git-hooks/commit-msg`
+
+**Validates:**
+- Commit message format: `type(scope): description`
+- Valid types: feat, fix, perf, refactor, test, docs, build, ci
+- Minimum description length: 10 characters
+- Maximum first line: 72 characters (warning)
+
+**Example valid commit:**
+```
+feat(parsers): add UniswapV2 parser with event validation
+
+- Implements ParseLog() for Swap events
+- Adds token extraction from pool cache
+- Includes comprehensive validation rules
+- Achieves 100% test coverage
+
+🤖 Generated with [Claude Code](https://claude.com/claude-code)
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+### Local Testing Commands
+
+```bash
+# Quick pre-commit check
+make pre-commit
+
+# Full local CI validation (mimics GitHub Actions)
+make validate
+
+# Individual checks
+make fmt           # Format code
+make test          # Run all tests
+make test-coverage # Run tests with 100% coverage enforcement
+make lint          # Run linters
+make security      # Security scan
+
+# Build
+make build
+
+# Dependencies
+make deps-tidy
+make deps-check
+```
+
+## GitHub Actions Pipeline
+
+### Workflow: v2-ci.yml
+
+**Triggers:**
+- Push to `feature/v2-**` or `feature/v2/**` branches
+- Pull requests to `feature/v2-prep` or `master`
+- Manual workflow dispatch
+
+**Environment:**
+- Go version: 1.25
+- Minimum coverage: 100%
+- golangci-lint version: v1.61.0
+
+### Pipeline Jobs
+
+#### 1. Pre-Flight Checks
+
+**Purpose:** Validate branch naming and commit messages
+
+**Checks:**
+- Branch name follows convention: `feature/v2/<component>/<TASK-ID>-<description>`
+- Commit message follows format: `type(scope): description`
+
+**Example branch names:**
+```
+feature/v2/parsers/P2-002-uniswap-v2-base
+feature/v2/cache/P3-001-address-index
+feature/v2/validation/P4-001-validation-rules
+```
+
+**Failure behavior:** Block pipeline if validation fails
+
+#### 2. Build & Dependencies
+
+**Purpose:** Ensure code compiles and dependencies are correct
+
+**Steps:**
+1. Set up Go 1.25
+2. Download and cache dependencies
+3. Verify dependencies
+4. Check go.mod tidiness
+5. Build all packages
+6. Build main binary (if exists)
+
+**Caching:**
+- Go modules: `~/go/pkg/mod`
+- Build cache: `~/.cache/go-build`
+- Cache key: `${{ runner.os }}-go-${{ GO_VERSION }}-${{ hashFiles('**/go.sum') }}`
+
+**Failure behavior:** Pipeline stops if build fails
+
+#### 3. Code Quality & Linting
+
+**Purpose:** Enforce code quality standards
+
+**Checks:**
+1. **gofmt** - Code formatting
+2. **go vet** - Static analysis
+3. **golangci-lint** - Comprehensive linting
+4. **gosec** - Security scanning
+5. **TODO/FIXME detection** - Warning only
+
+**Configuration:** `.golangci.yml`
+
+**Enabled linters (40+):**
+- errcheck, gosimple, govet, ineffassign, staticcheck, typecheck, unused
+- bodyclose, cyclop, dupl, errname, exhaustive, exportloopref
+- gocognit, goconst, gocritic, gocyclo, godot, goimports
+- gomnd, gosec, lll, misspell, nakedret, nestif
+- And many more...
+
+**Failure behavior:** Pipeline stops if linting fails
+
+#### 4. Unit Tests (100% Coverage Enforcement)
+
+**Purpose:** Run all tests with mandatory 100% coverage
+
+**Steps:**
+1. Run tests with race detector
+2. Generate coverage report
+3. Calculate coverage percentage
+4. **ENFORCE 100% COVERAGE REQUIREMENT**
+5. Upload coverage to Codecov
+6. Generate HTML coverage report
+
+**Coverage calculation:**
+```bash
+COVERAGE=$(go tool cover -func=coverage.out | grep total | awk '{print $3}' | sed 's/%//')
+
+if (( $(echo "$COVERAGE < 100" | bc -l) )); then
+    echo "❌ COVERAGE FAILURE"
+    exit 1
+fi
+```
+
+**Failure behavior:** Pipeline STOPS if coverage < 100%
+
+**Artifacts uploaded:**
+- `coverage.out` - Coverage profile
+- `coverage.html` - HTML coverage report
+
+#### 5. Integration Tests
+
+**Purpose:** Test component interactions
+
+**Triggers:**
+- Commit message contains `[integration]`
+- Pull request events
+
+**Tests:**
+- Integration tests (tag: `integration`)
+- End-to-end tests (if exists)
+
+**Timeout:** 30 minutes
+
+#### 6. Performance Benchmarks
+
+**Purpose:** Ensure performance targets are met
+
+**Triggers:**
+- Manual workflow dispatch with `run_benchmarks: true`
+- Commit message contains `[bench]`
+
+**Benchmarks:**
+- Parser performance: < 5ms per transaction
+- Arbitrage detection: < 10ms
+- End-to-end: < 50ms
+
+**Command:**
+```bash
+go test -bench=. -benchmem -benchtime=10s ./...
+```
+
+**Artifacts uploaded:**
+- `benchmark.txt` - Detailed benchmark results (retained 90 days)
+
+#### 7. Decimal Precision Tests
+
+**Purpose:** Validate critical decimal handling
+
+**Tests:**
+- Decimal scaling accuracy
+- Rounding error accumulation
+- Cross-protocol decimal handling
+- Edge case decimal values
+
+**Failure behavior:** Pipeline stops if decimal tests fail
+
+#### 8. Modularity Validation
+
+**Purpose:** Ensure component independence
+
+**Checks:**
+1. Each `pkg/*` compiles independently
+2. No circular dependencies
+3. Standalone executability
+
+**Command:**
+```bash
+for dir in pkg/*/; do
+    (cd "$dir" && go build .) || exit 1
+done
+```
+
+**Dependency check:**
+```bash
+godepgraph ./... | grep -i cycle && exit 1
+```
+
+**Failure behavior:** Pipeline stops if modularity fails
+
+#### 9. Final Validation Summary
+
+**Purpose:** Aggregate all results and determine deployment readiness
+
+**Checks all jobs:**
+- Pre-flight ✅
+- Build ✅
+- Code quality ✅
+- Unit tests (100% coverage) ✅
+- Modularity ✅
+- Decimal precision ✅
+
+**Generates:**
+- CI/CD summary markdown
+- Deployment readiness status
+
+**PR Comments:**
+- Automatically comments on PRs with summary
+
+**Failure behavior:**
+- Exit 0 if all checks pass
+- Exit 1 if any check fails
+
+## Performance Optimizations
+
+### Caching Strategy
+
+**Go Modules Cache:**
+```yaml
+uses: actions/cache@v4
+with:
+  path: |
+    ~/.cache/go-build
+    ~/go/pkg/mod
+  key: ${{ runner.os }}-go-${{ GO_VERSION }}-${{ hashFiles('**/go.sum') }}
+  restore-keys: |
+    ${{ runner.os }}-go-${{ GO_VERSION }}-
+```
+
+**Benefits:**
+- Faster dependency downloads
+- Reduced bandwidth usage
+- Faster builds (2-5x speedup)
+
+### Parallel Execution
+
+**Jobs run in parallel:**
+- Code quality & Unit tests (independent)
+- Modularity & Decimal tests (after unit tests)
+- Integration & Benchmarks (after unit tests)
+
+**Estimated pipeline time:**
+- Pre-flight: 30 seconds
+- Build: 1-2 minutes
+- Code quality: 2-3 minutes
+- Unit tests: 3-5 minutes
+- Integration tests: 5-10 minutes
+- Total: 10-15 minutes (with caching)
+

+5. **Follow branch naming convention**
+6. **Write descriptive commit messages**
+
+### For Code Reviewers:
+
+1. **Check CI/CD status** before reviewing code
+2. **Verify test coverage** (should always be 100%)
+3. **Review security scan results**
+4. **Ensure modularity is maintained**
+5. **Verify performance benchmarks** (if applicable)
+
+### For Maintainers:
+
+1. **Monitor pipeline success rate**
+2. **Update dependencies regularly**
+3. **Review and update linter rules**
+4. **Optimize caching strategy**
+5. **Keep documentation up to date**
+
+## Troubleshooting
+
+### Common Issues:
+
+**1. Coverage not 100%:**
+```bash
+# View uncovered lines
+make test-coverage
+
+# Check specific package
+go test -coverprofile=coverage.out ./pkg/parsers
+go tool cover -func=coverage.out | grep -v "100.0%"
+```
+
+**2. Linting failures:**
+```bash
+# Run locally
+make lint
+
+# Auto-fix some issues
+golangci-lint run --fix
+```
+
+**3. Test failures:**
+```bash
+# Run with verbose output
+go test -v ./...
+
+# Run specific test
+go test -v -run TestSpecificTest ./pkg/parsers
+```
+
+**4. Build failures:**
+```bash
+# Clean and rebuild
+make clean
+make build
+
+# Check dependencies
+make deps-verify
+make deps-tidy
+```
+
+## Future Enhancements
+
+### Planned Improvements:
+
+1. **Automated Performance Regression Detection**
+   - Compare benchmarks against baseline
+   - Fail if performance degrades > 10%
