An eviction recorded "nothing owed" whenever it ran over a session with no provider child of its own, and the retry then read that record in preference to the child in front of it. A session suspended to an agent terminal is exactly that shape, and the trip back to native re-acquires into the SAME session object rather than replacing it, so the next close skipped both the dead-generation settlement and the lease release — leaving the record claiming a live owner this host had just stopped, and a pending send unsettled. The obligation is now derived the way the quit sweep already derived it, from one shared predicate: a live child always owes a wind-down, and a remembered `false` only carries the obligation forward, never cancels it. Also drops a memoization in the history page that could never hit. Its key was the snapshot's items array, which the reducer rebuilds on every `snapshot()` call, so each backward page allocated a fresh key; the one reader that does share a snapshot across pages reads forward and never calls it. The comment claimed a multi-page read filtered once, which was not true of either path. Tests: the handoff round trip that strands the lease, and the quit sweep picking up an eviction whose close retry never came.
