 # Implementation Log
 
+## 2026-07-02
+
+- Hardened Windows background operation so users do not need to keep a visible
+  console window open:
+  - `scripts/start_bot.py` now starts `app/main.py` with `pythonw.exe` when it is
+    available.
+  - `scripts/_watchdog.py` uses the same `pythonw.exe` restart path.
+  - `scripts/setup_scheduler.ps1` registers scheduled PowerShell tasks with
+    `-WindowStyle Hidden` and marks task settings as hidden.
+- Updated `README.md` with the background-operation rule and the preferred
+  manual start command.
+
