/**
|
|
* C216 — the ONE ordering vocabulary of the acervo list: the recordings source
|
|
* (C219) and the web speeches source (C216) share the options, the labels, the
|
|
* `recentes` default (never serialized) and the duration gate. Each domain owns
|
|
* the mapping to its Payload order (recordings default `-createdAt`, web
|
|
* `-speechAt`); a duration order only lists rows with a measured duration,
|
|
* because Postgres sorts NULLS FIRST on DESC.
