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:query(arena): the guard reads `e is ...`, but no insert names `kind:` - there is no tag to read; tag the inserts (`insert(arena, kind: player) { ... }`) first

// `is` on a kindless store refuses loudly: no insert names `kind:`, so
// there is no tag to read. Tag the inserts first.
