Merge eureka/aetheria-gravity-floater-fixtures-wells (floater-fixtures-wells, head d6380ca8)

Origin branch lagged at c631e09f; merged the closed head d6380ca8 from the shared object store (branch hands/ag4-floater-fix, unpushed).

Spec aetheria-gravity:cut_spec:cut-floater-fixtures-wells.r1; report h1; Soul s1 holds.
