What

A worker that never became ready and exited for a specific known cause is now classified as crashed rather than passing quietly, so failed background work shows up instead of disappearing.

Details
  • The new condition sits alongside the existing bad working directory, repeated attempt and last exit cause checks, any of which force the crashed outcome.
  • Feeds the existing tengu_bg_worker_exit telemetry.
Evidence

tengu_bg_worker_exit

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
