Sub-ticket of MARS-112 api-images: 67 orphan files in shared flat uploads/2026/ with no DB owner (mars nor pluto) post tenant-isolation backfill — cross-app reconciliation pass: identify (pluto-deleted-file-remains / pre-DB test / stray), decide trash-vs-assign. Not Mars-exclusive; coordinate with pm-pluto + coder-apiimages. Mars set confirmed complete (5,690), so none are Mars's. · mars
