# Compact Status - 01-10-2025

**Focus**: Configuration security completion and integration test planning

**Key Accomplishments**:
- ✅ Committed security hardening work (resource exhaustion, info disclosure, type safety)
- ✅ Made worktrees experimental and default OFF (based on user feedback about complexity)
- ✅ Implemented component-level validation (350+ lines) with system resource checks
- ✅ Wrote 23 comprehensive tests for component validation (all passing)
- ✅ Designed integration test strategy (9 scenarios, ~20-25 tests)
- ✅ Created comprehensive worktree documentation (.docs/features/worktrees/, 3000+ lines)

**Critical Decisions**:
- **Worktrees Experimental**: Default OFF (`useWorktreesByDefault: false`), opt-in via `--use-worktree` flag or env var. Rationale: Too complex for 95% of users, preserve for power users who need isolation.
- **Component Validation Non-Fatal**: Logs warnings with recommendations but doesn't block startup. Rationale: Better operator experience, catches misconfigurations before runtime issues.
- **Integration Tests Priority**: 9 test scenarios planned to validate config flows end-to-end through system. Rationale: Unit tests insufficient for catching config → behavior integration bugs.

**Next Priority Actions**:
- [ ] Create test bootstrap helper (`tests/fixtures/test-bootstrap.ts`)
- [ ] Add environment cleanup utilities (`tests/fixtures/test-helpers.ts`)
- [ ] Write 7 integration test scenarios (env vars, security, validation, defaults, EventBus, output, worktrees)

**Critical Issues**:
- **NONE** - All critical security and architectural issues resolved

**Key Files Modified**:
- `src/core/config-validator.ts` - **NEW**: Component-level validation (350+ lines)
- `src/core/configuration.ts` - Added `useWorktreesByDefault: false`, marked EXPERIMENTAL
- `src/bootstrap.ts` - Integrated validation at startup, logs warnings
- `src/cli.ts` - Changed to `--use-worktree` (opt-in), added EXPERIMENTAL warnings
- `tests/unit/core/config-validator.test.ts` - **NEW**: 23 comprehensive tests
- `.docs/features/worktrees/README.md` - **NEW**: Complete worktree guide (local only)

**Context Notes**:
Configuration security is complete (schema validation + component validation + 48 tests). Worktrees simplified to experimental opt-in. Next major work is integration testing (9 tasks in todo list). Previous session's security work was accurate and comprehensive. All changes committed cleanly to `test/comprehensive-testing` branch.

**Commits This Session**:
- `d43dc45` - Security hardening (previous session, committed this session)
- `3039beb` - Worktrees experimental default OFF
- `711e22b` - Component-level configuration validation
