Seen again, and the flake work that just landed on main (50f1a9be) does not cover it. That change fixed this same test at line 115, replacing a `b.groups.first { … }` with the new `awaitGroupList` helper. The failure is at **line 143**:
```kotlin
assertEquals(1L, session.groups.first().first { it.gid == gid }.unread)
```
which is a bare `.first()` on the same shared, conflated list — exactly the hazard `GroupListWaits.kt` documents ("`first { predicate }` is waiting for an emission, not for a value … the emission carrying the value can be folded away before a collector is attached"), on a session that has only just been opened by the reply. The helper exists now; this line was simply not in the set.
Tally so far, same test, same line: 1 failure in 3 rounds at tip 13c0120b, and 1 in 5 at the merged tip 0598d49d (one gate run plus four forced `cleanJvmTest` rounds, all four green). 2 in 8.
The fix looks like the one already written: re-read the shared value instead of awaiting an emission, i.e. `awaitGroupList("count the reply's chat as unread") { … }` at that line, with the assertion kept.
