This commit implements Phase 2 of the CHORUS Task Execution Engine development plan, providing a comprehensive execution environment abstraction layer with Docker container sandboxing support. ## New Features ### Core Sandbox Interface - Comprehensive ExecutionSandbox interface with isolated task execution - Support for command execution, file I/O, environment management - Resource usage monitoring and sandbox lifecycle management - Standardized error handling with SandboxError types and categories ### Docker Container Sandbox Implementation - Full Docker API integration with secure container creation - Transparent repository mounting with configurable read/write access - Advanced security policies with capability dropping and privilege controls - Comprehensive resource limits (CPU, memory, disk, processes, file handles) - Support for tmpfs mounts, masked paths, and read-only bind mounts - Container lifecycle management with proper cleanup and health monitoring ### Security & Resource Management - Configurable security policies with SELinux, AppArmor, and Seccomp support - Fine-grained capability management with secure defaults - Network isolation options with configurable DNS and proxy settings - Resource monitoring with real-time CPU, memory, and network usage tracking - Comprehensive ulimits configuration for process and file handle limits ### Repository Integration - Seamless repository mounting from local paths to container workspaces - Git configuration support with user credentials and global settings - File inclusion/exclusion patterns for selective repository access - Configurable permissions and ownership for mounted repositories ### Testing Infrastructure - Comprehensive test suite with 60+ test cases covering all functionality - Docker integration tests with Alpine Linux containers (skipped in short mode) - Mock sandbox implementation for unit testing without Docker dependencies - Security policy validation tests with read-only filesystem enforcement - Resource usage monitoring and cleanup verification tests ## Technical Details ### Dependencies Added - github.com/docker/docker v28.4.0+incompatible - Docker API client - github.com/docker/go-connections v0.6.0 - Docker connection utilities - github.com/docker/go-units v0.5.0 - Docker units and formatting - Associated Docker API dependencies for complete container management ### Architecture - Interface-driven design enabling multiple sandbox implementations - Comprehensive configuration structures for all sandbox aspects - Resource usage tracking with detailed metrics collection - Error handling with retryable error classification - Proper cleanup and resource management throughout sandbox lifecycle ### Compatibility - Maintains backward compatibility with existing CHORUS architecture - Designed for future integration with Phase 3 Core Task Execution Engine - Extensible design supporting additional sandbox implementations (VM, process) This Phase 2 implementation provides the foundation for secure, isolated task execution that will be integrated with the AI model providers from Phase 1 in the upcoming Phase 3 development. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
