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
// Tag synthesis (write-demand): the store holds Players and Enemies over
// ONE folded Health column, and because inserts name kinds the store
// synthesizes a hidden `kind` column (seed order, 1-based: player=1,
// enemy=2). The query reads `e.kind` like any column — no hand tag, no new
// syntax. When this landed, 690_273's manual tag became the same shape
// minus synthesis.
