-# Changes Summary - ComfyUI Face Shaper Update
-
-## Overview
-This update synchronizes ComfyUIFaceShaper with the latest SVG, implementing refreshed ear geometry, integrating the nose tip control within the main nose path, and removing obsolete nose_tip geometry/settings.
-
-## Changes Implemented
-
-### A) Updated Ear Geometry
-- **Replaced ear coordinates**: Updated `ear_left` and `ear_right` with new SVG-derived, viewBox-normalized coordinates from path184 (which contains both ears in 2 subpaths)
-  - `ear_left`: 5 points starting at (0.187500, 0.484375) - left ear, subpath 1
-  - `ear_right`: 5 points starting at (0.796875, 0.609375) - right ear, subpath 2
-- **Maintained controls**: Existing ear controls (pos_x/pos_y, size_x/size_y) remain functional
-- **Transform pipeline**: Ears are transformed via centroid → scale → position offsets → pixel conversion
-- **Rendering**: Drawn with `draw.line` using existing stroke logic
-
-### B) Removed Obsolete nose_tip Geometry
-- **Removed from FEMALE_FACE**: Deleted separate `nose_tip` geometry (5 points)
-- **Removed INPUT_TYPES settings**:
-  - `nose_tip_size_x` (FLOAT, was default 1.0, min 0.5, max 2.0)
-  - `nose_tip_size_y` (FLOAT, was default 1.0, min 0.5, max 2.0)
-- **Updated method signature**: Removed `nose_tip_size_x` and `nose_tip_size_y` from `draw_face()` parameters
-- **Removed rendering code**: Deleted separate nose_tip drawing section
-- **Updated settings_list**: Adjusted import/export indices (now 57 parameters instead of 59)
-
-### C) Integrated Nose Tip Control
-- **Kept nose_tip_pos_y**: Single control parameter (FLOAT, default 0.0, min -0.2, max 0.2, step 0.005)
-- **Updated nose geometry**: 13 points from SVG path46 (was 11 points)
-- **Identified tip points**: Indices 5, 6, 7 are the 3 middle-most, lowest-Y points of the nose polyline
-  - Index 5: (0.487500, 0.656250) - left tip
-  - Index 6: (0.500000, 0.659375) - center point (lowest)
-  - Index 7: (0.512500, 0.656250) - right tip
-- **Applied offset**: `nose_tip_pos_y` is applied ONLY to these 3 points after nose scaling and position transforms, before pixel conversion
-- **Single draw call**: Nose is still drawn exactly once with `draw.line()`
-
-### D) Settings List Updates
-- **SETTINGS_LIST_LENGTH**: Still 60 (for future expansion)
-- **Actual parameters**: 57 (55 feature controls + 2 canvas dimensions)
-  - Previously: 59 parameters
-  - Reduction: Removed 2 nose_tip size controls
-- **Updated indices**: All parameters after nose_tip_pos_y shifted down by 2
-  - `nose_tip_pos_y`: index 49
-  - `camera_distance`: index 50 (was 52)
-  - `camera_pos_x`: index 51 (was 53)
-  - `camera_pos_y`: index 52 (was 54)
-  - `fov_mm`: index 53 (was 55)
-  - `line_thickness`: index 54 (was 56)
-  - `canvas_width`: index 55 (was 57)
-  - `canvas_height`: index 56 (was 58)
-
-## Validation Results
-
-All validation checks passed:
-- ✓ FEMALE_FACE dictionary updated correctly
-- ✓ INPUT_TYPES parameters correct
-- ✓ draw_face signature correct
-- ✓ Nose rendering logic correct (single draw call with integrated tip control)
-- ✓ Settings list handling correct
-
-## Backward Compatibility
-
-**Breaking Changes**:
-- Any code passing `nose_tip_size_x` or `nose_tip_size_y` will need to remove those parameters
-- Settings lists exported with the old format (59 params) can still be imported but indices 50-51 will be ignored
-
-**Maintained**:
-- Node name/category unchanged: CATEGORY="face", display name "Face Shaper"
-- All other controls remain the same
-- Settings export/import/reset behaviors intact
-- Default sliders reproduce the updated SVG exactly
-
-## Files Modified
-
-1. `face_shaper.py`:
-   - Updated docstring
-   - Updated FEMALE_FACE dictionary (ears, removed nose_tip)
-   - Updated INPUT_TYPES (removed nose_tip sizes)
-   - Updated draw_face signature
-   - Updated settings import section
-   - Updated nose rendering with integrated tip control
-   - Removed separate nose_tip rendering
-   - Updated settings export list
-   - Updated SETTINGS_LIST_LENGTH comment
-
-2. `test_implementation.py`:
-   - Updated test expectations for new geometry
-   - Updated test expectations for removed parameters
-   - Updated parameter count (57 instead of 59)
-
-3. `validate_changes.py` (new):
-   - Comprehensive validation script for all changes
-   - Can run without full dependencies
-
-## Testing
-
-Run validation:
-```bash
-python3 validate_changes.py
-```
-
-Run tests (requires numpy, torch, PIL):
-```bash
-python3 test_implementation.py
-```
-
-## Visual Changes
-
-With default settings:
-- Ears now appear in their updated positions from the latest SVG
-- Nose renders identically to before (tip integrated, no visual change at default)
-- Adjusting `nose_tip_pos_y` moves only the 3 tip points up/down subtly
