# OrbitHub Codex Build Prompt (Pure C++ / Qt6 Widgets)

You are Codex. You will implement OrbitHub entirely in C++ using Qt6 Widgets.

The previous Python/Shiboken implementation is abandoned.

## Rules

- Use modern CMake
- Use Qt6 Widgets only
- Use C++17 or newer
- Never block the GUI thread
- Use Git for checkpointing
- Maintain docs/PROGRESS.md

## Required Git Workflow

Create milestone branches:
- milestone-0-restart-cpp
- milestone-1-storage

Make small logical commits.

Tag milestone completions:
- v0-m0-done
- v0-m1-done

## Milestone 0 Deliverable

Implement:
- ProfilesWindow (QMainWindow)
- SessionWindow (QMainWindow)
- QTabWidget hosting placeholder QWidget
- main.cpp wiring

Stop after Milestone 0 is complete and tagged.
