What
When the Claude Code daemon (a background process) registers a worker, it reads back a value called worker_epoch from the response. This code was pulling that value from the wrong variable, so it was parsing a value that didn't actually hold the epoch number. This has been fixed so worker_epoch is now read from the correct response object.
Why
Before this fix, worker_epoch would have come out as NaN or some other garbage value instead of the real number, since the code was reading it from the wrong place. That could confuse any logic that depends on tracking a worker's epoch correctly.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding doesn't say what worker_epoch is used for downstream, so the practical impact of the garbage value is inferred only generally.
