Information about provability could be propagated downwards inside the proof:

if all premises of a rule are provable, the conclusion is provable
if a sequent is not provable and above a reversible rule, the conclusion of this rule is not provable

This would in particular allow to avoid the attached situations with a meaningless orange turnstile: orange2 orange1
