Broken The test itself needs fixing.
Sibling-field union (`player: Player, enemy: Enemy` in the store seed) is not the store surface. The signed declaration was `entity: Player | Enemy`. These pins must not stay green in stdlib.
Failure Output
error[KORU161]: std/store:insert(arena): column 'damage' is not a leaf of kind 'player' — player holds health, score
--> tests/regression/600_STDLIB/690_STORE/690_284_insert_foreign_leaf_refused/input.k:21:0Code
// A kinded insert names only that member's leaves. `damage` belongs to
// enemy; a player row that writes it is refused — zero-fill is the
// call site's job, not a back door for the other kind's columns.
