# R05: after-side rerun

After [4b55798444](https://git.cafe/pingdotgg/t3code/commit/4b557984448fd3d2e5bb506b3d9ff180e32f7748), OpenCode 2.2.6, Linux x86_64. Fresh synthetic data only. Actual UTC timestamps; private model labels replaced by `<model>`. Browser Date is frozen for visual consistency and is not elapsed-time evidence.

Outcome unchanged. After a READY initial turn, the identical sleep 20; echo done driver starts run 2. At 13:50:19.030 the real bash and sleep processes are alive with one pending command. Native completion at 13:50:38.930 contains done, and a continuation notification is persisted at 13:50:38.992: Command "sleep 20; echo done" finished, source background_command, outcome completed. The actual web client renders that notification and replies The background shell completed and printed done. At 13:51:11.338 both PIDs are absent, roster [], and all 3 runs are completed. This covers successful natural completion only. No new stills were needed.
