   - The owner side-by-sides the camp and highway aerials against `?refShadow=1`. The first candidate failed exactly that review.
   - Status 2026-10-03: draft PR #423; two bias fixes landed (hold during load; drawable level), start-pose defect persists (GPU-scene path + bias ≥2 renders coarse levels invisibly); counters: `byMove` repeatable at labelled ticks. Owner side-by-side vs `?refShadow=1` still owed (🙋).
