- The recorded reply: 27 September 2026, from the model named in its header, with the vendor's defaults, no system prompt and one turn. The question named no product and showed no screen.
- The screens: one product's desktop app in the run of 19 September 2026, from the course's own log; its settings, captured on 18 September 2026; the two other products' screens, 18 September 2026. English interfaces, one account per product. The run's files were read on 19 September 2026.
- The maker's page on how its cloud sessions work, "Claude Cowork architecture overview", read on 27 September 2026: the account keeps "sessions and files", for a time the page does not state.
