Actually, I completely forgot about Patrick's recent ref-transaction hook. See the "reference-transaction" section of githooks(7). They do more than you'd need, but you should be able to write a hook that just looks for updates to HEAD, or updates to the ref that HEAD is pointing at. The code was introduced in 6754159767 (refs: implement reference transaction hook, 2020-06-19), so you'll need Git v2.28.0 or later. -Peff
