# Compact Status - 30-09-2025

**Focus**: Critical security hardening and configuration architecture improvements

**Key Accomplishments**:
- ✅ **Security**: Added resource exhaustion protection (max 32 CPU cores, 64GB memory, 1h timeout)
- ✅ **Security**: Implemented CLI sanitization to prevent information disclosure (shows ranges not exact values)
- ✅ **Type Safety**: Eliminated non-null assertions by implementing "Parse, don't validate" with Zod defaults
- ✅ **Testing**: Fixed EventBus constructor issues in test fixtures
- ✅ **Testing**: Created 25 comprehensive security tests validating attack prevention

**Critical Decisions**:
- **Zod `.default()` over `.optional()`**: Schema transforms input into complete config (type-safe, no undefined)
- **Timeout max reduced to 1 hour**: Security over convenience, prevents infinite task DoS attacks
- **CLI output sanitization**: Shows ranges ("1-4GB") instead of exact values to prevent fingerprinting

**Next Priority Actions**:
- [ ] Create ListWorktrees MCP tool (foundation for worktree management)
- [ ] Create CleanupWorktrees MCP tool (solve 129+ stale worktrees problem)
- [ ] Add worktree safety validation (prevent unsafe deletions)

**Critical Issues**:
- **NONE** - All critical security issues from previous session have been resolved

**Key Files Modified**:
- `src/core/configuration.ts` - Added security bounds, Zod defaults, "Parse don't validate" docs
- `src/cli.ts` - Added sanitization function for secure config display
- `tests/security/resource-exhaustion.test.ts` - **NEW** - 25 security tests
- `tests/fixtures/factories.ts` - Added `createTestConfiguration()` helper
- `tests/fixtures/test-container.ts` - Fixed EventBus constructor

**Context Notes**:
Session started with `/catch-up` which revealed previous "successful" work had failing tests and critical security vulnerabilities. Fixed 4 major issues: resource exhaustion attack vectors, type safety problems, information disclosure, and test infrastructure bugs. All security fixes validated with comprehensive test suite. Project now has solid security foundation for worktree feature development.

**Todo List**: 5 completed (all security), 14 pending (worktree features, docs, additional security)
