# OrbitHub v0 Specification (Pure C++ / Qt6 Widgets)
## Overview
OrbitHub is a cross-platform native desktop application for managing and launching remote sessions.
Platforms:
- Windows 11
- Linux (Mint/Ubuntu-family)
- macOS
Implementation:
- 100% C++
- Qt 6 Widgets (no Qt Quick)
- CMake build system
- MIT License
This replaces the earlier Python-based architecture.
---
## UX Model
OrbitHub uses a two-window model:
1) Profiles Window (single instance)
- List of saved profiles
- Search box
- New / Edit / Delete
- Double-click connects
2) Session Window(s)
- QTabWidget
- One tab per session
- Close tab destroys session
- Placeholder view widget displays:
"OrbitHub Native Surface"
---
## Milestone 0
- Fresh C++/Qt repo scaffold
- App builds
- Profiles window launches
- Session window opens with placeholder tab
- Tag: v0-m0-done
---
## Milestone 1
- SQLite integration
- Profiles CRUD
- Connect loads profile name into tab
- Tag: v0-m1-done
---
## Milestone 2
- Extend profiles schema (`host`, `port`, `username`, `protocol`, `auth_mode`)
- Replace prompt-based create/edit with a structured profile dialog form
- Connect loads full profile details into session tab
- Session lifecycle states in UI (`Connecting`, `Connected`, `Failed`) with non-blocking updates
- Tag: v0-m2-done
---
## Milestone 3
- Real SSH backend using native `ssh` process (connect, disconnect, reconnect)
- Protocol backend abstraction with worker-thread execution
- RDP/VNC explicitly marked as not implemented in session UX
- Connect-time credential prompts (password/private key path) with no secret storage in DB
- Session tab controls: `Connect`, `Disconnect`, `Reconnect`, `Copy Error`
- Per-session timestamped event log and user-friendly error mapping
- Profile schema extended with `private_key_path` and `known_hosts_policy`
- Tag: v0-m3-done
---
## Milestone 4 (Draft)
- Make SSH sessions actually usable as interactive sessions inside OrbitHub
- Replace placeholder surface with interactive SSH terminal panel (stream output + send input)
- Add SSH host-key trust prompt flow for `Ask` policy
- Improve auth flow UX for password / private key at connect time
- Preserve responsive UI under active session output
- Add terminal/session utilities (`Clear Terminal`, improved output visibility)
- Keep session controls stable (`Connect`, `Disconnect`, `Reconnect`, `Copy Error`)
- Add validation and diagnostics coverage for host-key, auth, and reconnect behavior
- Planned Tag: v0-m4-done (after completion approval)
