//! CTX-0076 / issue #105 remainders in `context`: the `--output` write failure
//! was swallowed (`let _ = fs::write`, exit 0) so agents believed context was
//! persisted when the path was unwritable, and event/decision/progress query
//! failures were collapsed to confident empty output via
/// `.ok().unwrap_or_default()`.
