## Chief Engineer Guidance: Checklist Scope Refinement

Per Chief Engineer (Shusa) review, the 100-point QA checklist has been refactored:

### Batuta Orchestrator Checklist (Local)
- **Scope:** Sections IV & V only (40 points)
- **Focus:** Orchestration logic and code quality
- **Verification:** `make qa-local`
- **Score: 40/40** (normalized for applicable sections)

### Stack-Wide Checklist (Global)
- **Scope:** Full 100 points across all repositories
- **Requires:** CI environment with trueno, aprender, batuta side-by-side
- **Sections I-III:** Verified in component repos via their own CI

**Rationale:** Sections I-III (Trueno compute, Aprender ML) are component QA verified in their respective repositories. Batuta's role is Integration Verification - handling errors gracefully, not re-testing SIMD internals.

## Implemented Features

### [36] TUI Dashboard - COMPLETED
- **Technology:** ratatui 0.29 + crossterm 0.28
- **Features:**
  - Interactive navigation (↑/↓/j/k keys)
  - Details panel toggle (d key)
  - Health status indicators with colors
  - Graceful fallback for non-TTY environments
- **Tests:** 5 unit tests for Dashboard state management
- **File:** `src/stack/tui.rs` (460 lines)

### [40] Performance Optimization - COMPLETED
- **Technology:** Persistent file-based cache
- **Location:** `~/.cache/batuta/crates_io_cache.json`
- **Results:**
  - Before: 4.3 seconds
  - After (warm cache): 201ms
  - Offline mode: 373ms
- **Features:**
  - `--offline` flag for CI environments
  - TTL-based expiration (24 hours)
  - Automatic cache cleanup

### [47] Security Audit Investigation - COMPLETED
- **Finding:** 1 warning for `paste` crate (RUSTSEC-2024-0436)
- **Status:** Unmaintained, not a security vulnerability
- **Impact:** Transitive dependency from:
  - ratatui → paste
  - parquet → paste
  - simba → paste (via nalgebra)
  - rmp → paste
- **Resolution:** Cannot fix - upstream dependency
