```
(unset-hook client name &key scope target (key nil key-p) cancel-token timeout output-limit)
```

Remove one registered hook or hook-array entry and return its outcome.
SCOPE/TARGET and KEY follow SET-HOOK. The ordinary path never uses [set-hook](/en/tmux/latest/manual/set-hook/) -R,
but tmux may run a remaining native after-hook as a consequence of this
[set-hook](/en/tmux/latest/manual/set-hook/) command. The operation does not retry and validates the exact live
catalog before payload dispatch.
