I think that in the context of Bitcoin, the most useful definition of
covenant is that it's when the scriptPubKey of a utxo restricts the
scriptPubKey in the output(s) of a tx spending that utxo.
CTV, TLUV, etc do that; CSV, CLTV don't. ("checksig" per se doesn't
either, though of course the signature that checksig uses does -- if that
signature is in the scriptPubKey rather than the scriptSig or witness,
that potentially becomes a covenant too)
Cheers,
aj
