The Tracial Endpoint: Dark Energy as the Maximal-Entropy State

Dark energy as the maximal-entropy state: the value is postulated, the form is derived. Horizon entropy is computed at the observed constant; a conditional theorem forbids phantom crossing; the paper closes with an explicit ledger of what is proved, what is chosen and what is exposed, and falsifiable predictions with named tests and thresholds. / [ES] El punto final tracial: la energia oscura como estado de entropia maxima — el valor se postula, la forma se deriva; entropia de horizonte en la constante observada; teorema condicional que prohibe el cruce fantasma; libro mayor explicito y predicciones falsables con test y umbral nombrados.
