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
🎯 Compiler coordination: Passes: 20 (flow-based: elaborate, analysis, emission)Code
// K1 (2026-09-04): union members expand to folded columns. GameEntities
// holds Players and Enemies; both name (home, Health), so the store derives
// ONE Health column from its members. No tag, nothing asks — plain full-row
// inserts, plain query. The members are the column source of truth: adding a
// leaf to Player re-folds here.
