EpsilonWarning is dead code and mixes two contract return styles.

No field applies EpsilonWarning. The epsilon fields at lines 192-196 and 261-265 apply EpsilonContract only. The function also mixes std.contract.blame_with_message, which aborts, with 'Ok value, which is the validator-result style used elsewhere in this file. Either apply it to the two epsilon fields with one consistent style, or remove it.

EpsilonContract at lines 43-54 also has three branches that all return 'Ok value. Collapse them and keep the comment.

   if value <= 0 || value >= 1 then
