Under the hood
New internal helper tracks in-flight hooks per event and cleans up when they settle
What
A new internal function tracks hooks (commands Claude Code runs automatically at certain points) that are currently in flight, keyed by event and agent, with a settle(kind) call to mark completion and automatic cleanup when the tracking object is disposed.
Why
This is bookkeeping infrastructure for coordinating hook execution, likely to help Claude Code know when all hooks for a given event have finished running.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.

What consumes this tracking or what behavior depends on it isn't stated.
