What

A failed read of a background job's state now reports itself once per job before falling back to the cached copy, so intermittent storage problems are visible.

Details
  • fires on backend errors and on parse/read exceptions, and only if that job has not already reported
  • the event carries the errno and whether a cached state existed
  • oversized state files are skipped with a warning instead of being parsed
Evidence

tengu_bg_state_read_transient

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