pub fn reference_passes_through(
source: Dialect,
target: Dialect,
image: bool,
reference: &ResourceReference,
) -> boolExpand description
Whether a media reference converted from source reaches target as a
reference the upstream reads itself, so no bytes need fetching. Only
URLs to dialects with a URL form for that media, and file IDs between the
OpenAI dialects, survive conversion; every other reference is fetched.
Tests pin this against what the direct transforms actually keep.
