 ## [Unreleased]
 
 ### Added
-- Initial repository structure
-- CI infrastructure (GitHub Actions, pre-commit hooks)
-- Gateway sidecar framework
-- Sandbox container framework
-- CLI tool framework
+- **Core Infrastructure (Phase 1)**
+  - Repository structure with Python packaging (pyproject.toml, hatchling)
+  - GitHub Actions CI/CD workflow (lint, test, security scan)
+  - Pre-commit hooks for code quality
+  - Development tooling (Makefile, dev script)
+
+- **Documentation (Phase 1.5)**
+  - Architecture documentation with security model
+  - Configuration reference with examples
+  - API documentation for gateway endpoints
+  - Setup and troubleshooting guides
+  - ADR (Architecture Decision Record) for design decisions
+
+- **Gateway Module (Phase 2)**
+  - Flask REST API server with Waitress production server
+  - Session management with token-based authentication
+  - Git/GitHub client wrappers with policy enforcement
+  - Repository visibility checking (public/private mode enforcement)
+  - Worktree management for isolated per-session workspaces
+  - Rate limiting and audit logging
+  - Squid HTTP proxy integration for network filtering
+  - Private repository policy enforcement
+
+- **Container Infrastructure (Phase 3)**
+  - Gateway container (Squid proxy + Flask API)
+  - Sandbox container (development environment)
+  - Git/gh binary wrappers routing through gateway
+  - Session token credential helper
+  - Parameterized for standalone deployment
+
+- **CLI Tool (Phase 4)**
+  - `egg start` - Start sandbox environment with network setup
+  - `egg stop` - Stop and cleanup containers
+  - `egg status` - Show container and network status
+  - `egg exec` - Execute commands in sandbox
+  - `egg logs` - View container logs
+  - `egg config` - Configuration management (validate, show, init)
+  - YAML configuration with repository and GitHub App support
