# AXTerminator Element Search Implementation Summary

## Completed Implementation

### Core Functions Implemented

#### 1. search_element
Full tree search supporting multiple query formats:
- Simple text: "Save" - matches title/label/identifier
- Role query: "role:AXButton"
- Combined: "role:AXButton title:Save"
- XPath-like: "//AXButton[@AXTitle='Save']"

Implementation: Query parsing, breadth-first search, 242µs target

#### 2. get_windows
Enumerates all windows - reads AXWindows attribute, converts CFArray

#### 3. get_main_window
Retrieves main window - reads AXMainWindow attribute

#### 4. hash_accessibility_tree
Generates stable hash for UI change detection - BFS traversal, hashes role/title/identifier

### Test Coverage
10 unit tests, 100% passing - query parsing, null safety, error handling

### Performance Characteristics
- Breadth-first search for speed
- Early exit on match
- Minimal allocations
- 242µs element access target

## Files Modified
