D723 - A played window reads the host clock

Status: assumed Date: 2026-09-26

The GUI runs its workers on the host clock unless ORBISTOUN_CLOCK is set; the CLI, the loop and corpus runs keep the logical clock by default.

Why: a run is a measurement and has to repeat, which is what the logical clock is for. A window someone plays is not a measurement: on the hardware a title's clock is real time, and the logical clock advances a step per reading, so a guest thread spinning on the time counter runs game time several times faster than real time. An explicit setting still wins, and a replayed capture stays in step either way because its steps are keyed to flips (D721).

Rejected:

• The logical clock in the window: no guarantee of pace to a person holding a pad.
• The host clock everywhere: measured runs stop repeating.
