What

The record kept for each background session now stores how many monitors still have work to drain, which changes when an idle background session is retired.

Details
  • The count is only written when it is above zero.
  • The check that decides whether a session is a parked idle fork became its own method, and it now accepts a session recorded by a different CLI version as long as that session reports drainable monitors.
  • Change detection between records now compares kinds as a set, so reordering alone no longer counts as a change.

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