/**
 * Feedback exports carry the camera-original filename (#1224).
 *
 * Both exports used to select only `photos.filename` — the sanitized stored
 * name — so a photographer acting on client picks had nothing to match the
 * masters on disk with.
 *
 * The load-bearing case is the third one: `original_filename` is overwritten
 * the first time an edited render is uploaded over a proof (#745), so an
 * export that read it alone would name the render rather than the master and
 * silently stop matching. `source_filename` survives a replace by design
 * (migration 193) and must win.
