pub fn append_dashboard_log_to(path: &Path, msg: &str)Expand description
Append a timestamped line to the dashboard activity log at an explicit
path. Silently ignores I/O errors - the dashboard log is best-effort.
The path is a parameter so Dashboard can inject a test-isolated log
location, guaranteeing no dashboard-input test appends to the user’s real
~/.leviath/dashboard.log (see dashboard_log_path).
