Stock Screener Launcher
|
|
=======================
|
|
Startup sequence:
|
|
1. Generate HWID
|
|
2. Load stored license key — show activation dialog if none found
|
|
3. Verify license against Supabase (with 30-min offline grace period)
|
|
4. Silently check for and apply updates
|
|
5. Launch the bundled screener_gui
