The /channel/{kind}/{index}/headAmp row FIELD each analog head-amp capability WORD is
carried by — the one translation between the two vocabularies, declared once.
They differ for exactly one word, and deliberately: the capability is sens — the name of the
CONTROL the box exposes, which is what an adapter enumerating its inputs can honestly declare —
while the field is gainDb, the value the desk stores and publishes, in the desk's one unit.
Spelling that correspondence twice is how a narrowing silently stops narrowing: a lookup keyed
sens against a map keyed by the field finds nothing, reads as "not capable", and hides a
working preamp.
