The curator re-read all cited web sources (S29); nothing was executed. The ETC VFX image-sequence naming report v1.0 (2020) defines identification objects (show, VFX sequence, 4-digit VFX shot, image type with instance number, description, vendor and revision codes, alternate, multi-camera reference, frame number) composed into a file name with fixed separators kept even when a parameter is missing, consistent case (lower case preferred) and names independent of directory paths. Literal token spellings were lost in PDF text extraction.
