Second distinct flake in this suite today (gate run: MoveEast observed mid-move at the 5s window). The old accounting accrued elapsed only on empty polls — load-dependent effective window. Wall-clock deadline via Time.get_ticks_msec; ceiling 5s->10s (exit-on-arrival, costs nothing when healthy). Targeted suite 6/6. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
