Errors
WORK_DEAD_LETTERED
Runtime work exhausted its retry budget.
What failed
A work item retried until maxAttempts and moved to the dead-letter terminal state.
Why
The runtime stops retrying to avoid hot loops and preserve the last error for inspection.
What still works
Other work continues. The dead-lettered item remains inspectable and can be explicitly retried after the cause is fixed.
Fix
Inspect, fix the cause, then retry:
crux runtime inspect <workId>
crux runtime retry <workId>
