Assembly.LoadFrom can fail on volumes .NET misclassifies as remote; fall back to Assembly.Load(byte[]). Broaden exception handling to BaseException for pythonnet, and skip WebView2 warmup/taskkill when the instance lock is held by another process.
Windows prefers WebView2, Linux uses QtWebEngine only; pythonnet deps are win32-marked. Each QtWebEngine instance gets its own profile under data/webengine, and Chromium flags are sanitized before QApplication (--no-sandbox accepted only for explicit root/container use).
Windows runs 'cmd.exe /d /s /c <command>' as a string command line; Linux uses ['/bin/bash', '-lc', command]. Removes implicit shell=True behavior and aligns the agent system prompt per platform.
Import the pre-repair source tree as the history baseline.
Runtime data (data/), virtualenvs, bytecode caches and logs are
gitignored so local secrets and user state stay out of the repo.
