fix(multicall): resolve critical multicall parsing corruption issues
- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing - Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives - Added LRU caching system for address validation with 10-minute TTL - Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures - Fixed duplicate function declarations and import conflicts across multiple files - Added error recovery mechanisms with multiple fallback strategies - Updated tests to handle new validation behavior for suspicious addresses - Fixed parser test expectations for improved validation system - Applied gofmt formatting fixes to ensure code style compliance - Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot - Resolved critical security vulnerabilities in heuristic address extraction - Progress: Updated TODO audit from 10% to 35% complete 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

## 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
