Throwing work away
The one command that really does destroy something.
`git reset --hard` moves the branch, rewrites the index and overwrites your files. Uncommitted work is gone — no reflog, no object, nothing.
The commits are a different matter. They stay in the object store and the reflog still names them, so a branch moved by mistake is recoverable until a garbage collection runs.
Knowing which half is recoverable is the difference between a bad afternoon and a lost one.
