Module loss 

What an export to a lossy format gives up (mirrored ontology C8, the codec model’s points 3–5).

Each codec declares, per IR feature, whether it carries it exact, folded (merged into something coarser) or dropped. Before writing, an export lists every folded and dropped item in the model being exported, as GIMP warns before flattening layers; it then proceeds and keeps the report beside the output. The native folder is never the export’s destination, so what was folded or dropped still lives there. A native save has no report: it loses nothing.
