Wait — on a case-insensitive filesystem,

2026-01-07-...-49PGOG.md

and

...-49pgog.md

can't both physically exist as separate files. The

ls

shows both names because APFS here is case-preserving but case-insensitive — they're actually the same file shown via two name forms, OR git checked out both because git is case-sensitive. Let me verify what's real on disk vs what git tracks, because that determines the cleanup.
