The web app keeps the # reasoning hidden until status === "settled"; reading raw chain state was # always possible for anyone, before and after this change. # # On windows & dust: the acceptance/evidence windows are constructor params # (default 86400s each, so a no-arg deploy is unchanged). Filings must stake # at least MIN_STAKE_WEI (0.1 GEN); terms and evidence text are capped (2000 / # 5000 chars) so one oversized submission can't bloat every verdict prompt. # # Known residual (documented, deliberately unfixed): if BOTH sides submit # evidence and the validators persistently disagree, request_verdict keeps # failing and the pot stays locked in "evidence_open" — the default- # judgment path only covers missing submissions. An escape hatch here # would let a losing party dodge judgment by sabotaging consensus, so the # failure mode is kept loud rather than adding a refund loop that # undercuts the mechanism. # ---------------------------------------------------------------------------
