Recovering from a Bad Reset --hard

Three real commits. One destructive reset. Recovered in a single command.

git reset --hard HEAD~3 is a real, genuinely destructive command — it moves the branch pointer back three commits and overwrites the working directory to match, with no confirmation. Three real recipes, just committed, disappear from the branch instantly.\n\nBut reset --hard, like every ref-moving command, is itself recorded in reflog before it happens. HEAD@{1} always means "wherever HEAD was, one real step before its most recent move" — which, immediately after a bad reset, is exactly the good state from right before it. No searching required.

A Real, Destructive Mistake

git reset --hard HEAD~3

Three real commits, instantly gone from the branch — no confirmation, no warning. The working directory is overwritten to match, too.

The One-Command Undo

git reset --hard HEAD@{1}

HEAD@{1} means "one real step back in HEAD's own reflog" — immediately after the bad reset, that is exactly the good commit from right before it. No hash to look up, no grep required.

Confirming the Real Recovery

git log --oneline -4

All three real commits, back exactly where they were, plus whatever came before them.

HEAD@{1}

Reflog's own relative addressing — "one real step back from HEAD's current reflog position," regardless of what kind of operation caused that move. Confirmed directly in this lab: run immediately after a bad reset --hard, it pointed exactly at the good state from right before it.

🍲 Three Real New Commits

Three genuine recipes, committed normally.
