     The script:
       - cd's into a stable working directory
       - exports HERMES_HOME, PYTHONIOENCODING, VIRTUAL_ENV
-      - invokes ``pythonw -m hermes_cli.main [--profile X] gateway run``
+      - invokes a no-console ``pythonw -m hermes_cli.main [--profile X] gateway run``
         directly so the wrapper cmd.exe exits without a visible gateway console
 
+    uv-created venv launchers need special care: ``venv\\Scripts\\pythonw.exe``
+    can respawn the base interpreter as console ``python.exe``.  Reuse the same
+    resolver as direct detached starts so Scheduled Task launches use the base
+    ``pythonw.exe`` plus PYTHONPATH entries for the repo and venv site-packages.
+
     We intentionally do NOT inline PATH overrides here — cmd.exe inherits
     the per-user PATH the Scheduled Task was created with, and forcibly
     rewriting PATH tends to break Homebrew/nvm-style installations.
