kill the player

kill the player (statement, peer to win and lose) has the forms kill the player, kill the player <phrase-key>, and an optional when <condition> suffix; it is legal anywhere statements go: on and after clauses (entity or trait), on every turn [while …] daemons, define action bodies, and inside select and each blocks. The phrase key is the death text (define it like any phrase) and doubles as the recorded cause; a bare kill the player records the cause killed and shows only the platform's ending text.

The machinery, in order: the death text speaks, the platform's player-died event fires, and at end of turn the engine re-checks the player's actual life state; that re-check, not the event, is the final word. A story policy that revives the player during the turn (Dungeo's death-penalty machinery works this way) vetoes the ending; otherwise the game ends in defeat (game-lost, the death and endgame channels). Because the decision waits for end of turn, statements after the kill in the same body still run. There is no built-in "restart or undo?" prompt; that is client/story territory.

  shock-death:
    The current takes you before you can let go.
  wire-cold:
    Cold and inert. The breaker did its job.
  breaker-thrown:
    The breaker slams over and the hum dies with it.

The player who touches the wire straight away sees the death text and nothing after it; the game has ended in defeat:

> touch the wire
The current takes you before you can let go.

The player who throws the breaker first (a fresh game) lives:

> pull the lever
The breaker slams over and the hum dies with it.

> touch the wire
Cold and inert. The breaker did its job.

The when suffix is the whole gate: with a live wire, the kill fires; with a dead wire, it is skipped. Note the second when on phrase wire-cold: statements after a kill still run, so follow-up text must gate itself off the fatal case.
