Audit per-file syscall sequence across chown/chmod/utimensat/xattr/ACL paths, document parallelism status (rayon batch only on directory creation), and propose 5 reductions: cached-stat skip, fd-relative ops on the streaming path, dirfd batching, attribute deduplication, and a deferred metadata phase.

Audit metadata apply pipeline (chmod/chown/utimensat/setxattr/setfacl), quantify the 300K-syscall floor at 100K files, plan strace-c profiling, confirm rayon par_iter wiring through apply_metadata_from_file_entry (threshold 64), and enumerate io_uring statx, O_PATH fchownat, and skip-if-equal optimization candidates.
