+# Implementation Plan: Rich Thinking Trace Handling
+
+## Status: COMPLETE (2026-03-14)
+
+## Summary
+Implemented thinking trace parsing, model, persistence, and GUI rendering for AI responses containing `<thinking>`, `<thought>`, and `Thinking:` markers.
+
+## Files Created/Modified:
+- `src/thinking_parser.py` - Parser for thinking traces
+- `src/models.py` - ThinkingSegment model
+- `src/gui_2.py` - _render_thinking_trace helper + integration
+- `tests/test_thinking_trace.py` - 7 parsing tests
+- `tests/test_thinking_persistence.py` - 4 persistence tests  
+- `tests/test_thinking_gui.py` - 4 GUI tests
+
+## Implementation Details:
+- **Parser**: Extracts thinking segments from `<thinking>`, `<thought>`, `Thinking:` markers
+- **Model**: `ThinkingSegment` dataclass with content and marker fields
+- **GUI**: `_render_thinking_trace` with collapsible "Monologue" header
+- **Styling**: Tinted background (dark brown), gold/amber text
+- **Indicator**: Existing "THINKING..." in Discussion Hub
