The situation
It is Wednesday 27 May 2026, week 7. Priya replays the 20 April queue in staging. In R-1001's chat Aisha Rahman wrote: "Please keep emails short, I read them on my phone between night shifts, so no phone calls." An hour later R-1006, a new run, knew nothing of it.
"Can it remember?" asks Priya. Sam asks the other question: "Then what happens when R-1008 writes that the policy has changed?" This lesson answers both, traced through Aisha's sentence.
