logFile property

String? logFile
final

--log-file <path>: tee every line the CLI prints (assistant text, tool trace, diagnostics) to path as it is produced, so a run nested inside a parent CLI's output capture leaves a readable, tail -f-able trace file behind. The file is truncated on start. The FA_LOG_FILE env var is the twin default when the flag is absent (flag wins).

Implementation

final String? logFile;
