MT5 Master & Slave spawn · desktop sync (Spawner v2 not required)
Connect to load device details.
Recovery runs only while Launch-WebControl.bat is running.
Sync everything repairs accounts, pulls desktop MT5 servers/bases, applies chart presets, and writes SHA256 hashes to Logs\sync-all-manifest.json.
Find desktop MT5 & sync all: save WebRequest URLs in real MT5 (Tools → Options → Experts → OK), then click once — finds the AppData profile, saves it in settings.ini, and copies into templates, golden seed, and every Instance.
Sync brokers and presets from Slave ops (Sync everything) — same account store.
After connecting, accounts and symbol presets load automatically. Use Ctrl+F5 if the page looks outdated.
