Gotchas

• git log -S finds commits where the string was added OR removed. A commit that deleted a function surfaces as equally relevant to the one that added it — verify the direction of change.
• Squash merges erase commit-level traceability. git reflog only works locally and expires — if another contributor squashed and force-pushed, the original commits are unrecoverable.
