Does the prohibition of writing STaM 'shelo kesidran' (out of order) apply to correcting or completing individual letter components (such as a Yud not touching the Alef) after writing the next letter?
Synopsis
A major dispute among Acharonim whether adding a missing component (such as a Yud that does not touch, a missing tag, or the left spine of a Yud) after writing the subsequent letter violates the prohibition of writing out of order. The ruling depends on whether the letter already has its essential form without the missing element.
