Shotcut's EDL exporter writes one section per playlist with cuts and dissolves from program time 0 and no header lines; by default the reel name is the media base name (cut at the first dot, non-word characters replaced, padded or truncated to 8 characters), so files sharing their first eight characters collide; an option uses the stored hash instead. With proxies on, names may come from proxy files (producer inference).

Curator qualifications: Code read 2026-10-22; no export run. Proxy save-path rewrite (proxymanager.cpp, mltcontroller.cpp) from producer reading. Curator nuance: the base name stops at the first '.', so 'scene.v2.mov' becomes 'scene'.

Limitations: Code read 2026-10-22; no export run.
