 The acceptance cell was proven failing against PTY main `d5fabc3` and passing
-against validation-only fork head
-`4dd713e5cd71b8ba5cc6b07ffeae8b82e7a31e96`. That head merges detach candidate

-`1c625c75702e032ff5dc455976ad75005cd2c1c8`, which already contains the attach
-stream fixture prerequisite from #145. The validation-only ref is not a runtime
-dependency; after both corrections merge, the maintained cell runs against the
-packaged PTY on merged main.
+against the packaged PTY built from merged upstream main
+`7effe7b8c4ee22796f62188d321445027c8f5096`. That revision contains the attach
+stream fixture prerequisite from #145, intentional detach outcomes from #146,
+and explicit same-socket role replacement from #147. The maintained cell now
+runs directly against packaged PTY main; it has no validation-only runtime
+dependency.
