# Unenrol Lead Finder

`DELETE /api/experiments/{key}/lead-finder/enrol`

Close a lead-finder run: drop its assignment rows and its label from
``agent_lead.ab_arms``.

The inverse of the enrol route, and the reason a probe run is safe to make
at all — bookkeeping for one key, meaningless once the run is over, and
actively misleading if left behind (a cohort that looks real). Restricted
to ``lead_finder`` and to a card that is NOT running: closing a live
experiment's cohort out from under its readout is never what anyone meant.
