//! Regression for issue #190 (secondary): the rolling daily log files are named
//! `opencrabs.YYYY-MM-DD` with NO `.log` extension. The old
//! `path.extension() == "log"` checks therefore matched ZERO real log files, so
//! `logs status` reported `Log files: 0`, `logs view` found nothing, and
//! `cleanup_old_logs` never pruned anything. `is_log_file` matches the real
//! naming instead.

use crate::logging::is_log_file;

/// The synchronous self-healing writer (#190 primary) must actually create a
/// `opencrabs.<date>` file and write events into it — proving the wiring that
/// replaced the silently-dying `non_blocking` worker. The file it produces must
/// also be one that `is_log_file` recognizes, so the readers can see it.
