This describes version 0.2.2. See the support record for measured option combinations and backend limits; accepted options do not establish full compatibility.

Move files and directories with the policy-checked atomic rename operation. Declining an interactive overwrite, including EOF, returns status 1 and leaves both paths unchanged; other operands are still processed. A no-clobber skip remains a successful no-op.

Supports force/no-clobber/interactive selection (-f/-n/-i), update modes (-u/--update), backup controls (-b/--backup, -S), explicit target paths (-T), directory destinations, and verbose output. Cross-filesystem copy-and-delete fallback is excluded because public APIs cannot preserve all required mode/link/time semantics. POSIX EXDEV can now be classified using async 0.22.4 host-platform information. The source remains intact when rename or backup commit fails. Classification of EXDEV does not add a cross-device fallback. Windows rename error classification and the remaining interactive/backup/update combinations still need independent validation.

Same-path moves fail before prompting or making backups, except an explicit no-clobber/update-none skip. After rename, the source entry must have disappeared; a same-inode hard-link no-op reports failure and preserves both names. Public identity metadata is unavailable before the operation. Equal-time targets with -i or -u therefore reject explicitly: equal timestamps cannot distinguish an alias from a separate file. This includes separate files whose mtimes happen to match. Other processes recreating the source during rename also cause a postcondition error; no second deletion is attempted.

#Standalone metadata

Standalone --version prints exactly mv 0.2.2 followed by one newline. Standalone --help starts with Usage: mv, lists both metadata options, and ends with a newline. Both write to stdout, leave stdin unread, and exit with status 0. Exact-version publication and verification remain recorded separately in the support record.
