Last 2 .228 stragglers confirmed load/timing, not bugs: test 31 (companion recreate)
= contamination + ~108s reconcile cadence > 90s window; test 55 (immich restart) =
heavy stack restarts >120s under load but DOES return. Path to literally-green gate
is infra (bitcoin sync, re-quadletize .228) + minor test-window tuning. Optional
product improvement noted: independent ~30s companion-reconcile cadence.
