Interface TapPoint

The processor KIND that DEFINES this point — the one that occupies its segment and cannot leave it. A ProcessorKind token; absent means the segment is free and anything may be attached to it.

Pre-Fader and Post-Fader mean what they mean because the FADER runs between them; the same for the EQ and Pre-EQ/Post-EQ. Let the fader be dragged to the head of the chain and the two names stop describing anything — which is precisely what the old flat model allowed, and what "it makes no sense to reorder the pre-fader and post-fader" refuses. So the definer is pinned: the normaliser puts it back, and the door refuses to move it.

It is DATA, per point, per desk: a skeleton whose fader sits elsewhere says so here, and no code changes.

The wire token (Pre-Fader), stable for the life of the set.

The desk's own spelling of this point (Roland prints PRE FADER, SSL prints its Stem feed points differently again). It is the manufacturer's label, not translatable prose: a surface shows it as-is, the way a unit symbol is shown as-is.
