How Does a “Re-Org” Event Relate to a Soft Fork Activation Failure?

A "re-org" (reorganization) is when a node switches from one chain tip to a longer, competing chain, invalidating the blocks on the shorter chain. A soft fork activation failure could lead to a re-org if a significant minority of miners do not upgrade and continue to mine blocks that violate the new rules.

If this minority chain unexpectedly becomes longer than the chain following the new rules, the rest of the network could re-org to the non-upgraded chain, causing instability and a temporary rollback of transactions.
