# Implementation Plan: Rich Thinking Trace Handling

## Phase 1: Core Parsing & Model Update
- [x] Task: Audit `src/models.py` and `src/project_manager.py` to identify current message serialization schemas.
- [x] Task: Write Tests: Verify that raw AI responses with `<thinking>`, `<thought>`, and `Thinking:` markers are correctly parsed into segmented data structures (Thinking vs. Response).
- [x] Task: Implement: Add `ThinkingSegment` model in `src/models.py` to support optional thinking traces.
- [x] Task: Implement: Add `src/thinking_parser.py` with parse_thinking_trace utility.
- [ ] Task: Conductor - User Manual Verification 'Phase 1' (Protocol in workflow.md)

## Phase 2: Persistence & History Integration
- [x] Task: Write Tests: Verify that `ProjectManager` correctly serializes/deserializes messages with thinking segments.
- [x] Task: Implement: ProjectManager handles thinking_segments in dict structure (works with existing code).
- [ ] Task: Conductor - User Manual Verification 'Phase 2' (Protocol in workflow.md)

## Phase 3: GUI Rendering - Comms & Discussion
- [x] Task: Write Tests: Verify GUI rendering logic handles thinking segments.
- [ ] Task: Implement: Create `_render_thinking_trace` helper in `src/gui_2.py`.
- [ ] Task: Implement: Integrate thinking trace renderer into Discussion Hub.
- [ ] Task: Implement: Integrate thinking trace renderer into Comms History panel.
- [ ] Task: Conductor - User Manual Verification 'Phase 3' (Protocol in workflow.md)

## Phase 4: Final Polish & Theming
- [ ] Task: Apply specialized styling to thinking traces.
- [ ] Task: Add "Calculating..." indicator while agent is active.
- [ ] Task: Conductor - User Manual Verification 'Phase 4' (Protocol in workflow.md)
