Sokhi got a read-only error from the cover-art filler with NO ':ro' in his compose. Root cause: my earlier Tim fix added a statvfs pre-flight that bailed when f_flag & ST_RDONLY — but union/FUSE/network filesystems (mergerfs, rclone, NFS), ubiquitous in self-hosted setups, misreport those mount flags. A perfectly writable library could be flagged read-only and blocked. statvfs is a guess; the only honest test is whether an actual write raises EROFS. - Removed the statvfs pre-flight entirely. Read-only is now detected solely from a real EROFS on the embed write, which also fast-fails the remaining files (so no statvfs needed for the fast-fail Tim wanted either). - Broadened the user message: a genuine read-only mount isn't always ':ro' — could be a read-only host/NFS/SMB mount or a mergerfs read-only branch. Tests: writable FS succeeds even when statvfs would claim read-only (the regression), real-EROFS-on-write still flagged + bails the rest, EACCES still not conflated with EROFS. Dropped the now-moot Windows-statvfs test (statvfs is no longer referenced). 445 art/cover/repair tests pass.
