Narrowing the live-writer check to only git ... commit|add makes the decision tree misclassify other index-writing commands (for example merge, rebase, checkout, reset, stash, or update-index) as “Dead,” which then sends operators down the stale-lock removal path. In the documented saturation scenario, that can remove a lock from an actually active Git writer and risk index corruption or broken in-flight operations; this is a regression from the previous safer probe scope in this same memo.
