What

The step that decides a background task has come to rest now reports three outcomes instead of two: a dead worker generation, a normal settle, or nothing to do.

Details
  • Dead generations record a deadEpochReapedAt timestamp rather than the mid-work reap timestamp.
  • In that case the first terminal time is taken from the previous update time instead of the current one.
Evidence

deadEpochReapedAt

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