Two things changed:\n\n- one path now stops early when the setup in use sends compaction summaries\n\n- the check that decides whether to re-run queued work now also counts hidden internal messages marked as left over for that re-run\n\n**Why**\n\nThese changes affect what happens when a conversation is compacted or a turn is resumed.\n\n- Area: Compaction\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
