By payment rail
The agreement rides in the rail’s own field.
For each rail the published package supports, the field the ATR hash rides in, in the form that field can hold, with no new contract on any of them. Where a rail has no field for it, its page says what carries it instead.

Its ATR hash, the ATR’s fingerprint, is the proof bound to the transaction: change one byte of the ATR and it no longer matches.
