#cp

This documents version 0.2.1. The support record tracks platform verification and exact-version publication evidence separately.

Copy regular files and directory trees to new destinations with --no-preserve=mode (and -R/-r for trees). Source modes cannot be read with the public async 0.22.4 API, so default copying is explicitly unavailable. New files use 0666 & ~umask, and new directories use 0777 & ~umask. Supports -T, -v, and -H/-L/-P traversal. No-clobber (-n) and -u/--update modes (all, none, none-fail, older) can select a no-op without requiring copying capabilities. Non-recursive command-line symlinks are followed; recursive traversal rejects links unless explicitly enabled. The source tree, unsupported entries, cycles, and nested destinations are preflighted before mutation for each source operand. Existing regular-file overwrites are rejected because public file identity and truncation on the same open handle are unavailable. This includes same-file and hard-link aliases; no temporary-file rename is substituted for inode-preserving overwrite. The parser accepts -f/-i, backup controls (-b/--backup) and -S, but they do not enable replacement: overwrite requests fail during preflight, before an interactive prompt or backup mutation. A successful new-file copy with these flags does not establish their overwrite semantics.

-a/--archive and -p/--preserve (including an attribute list) are recognized but fail before creating output because the portable API cannot read and restore complete links, modes, ownership, and timestamps. See the support record.

#Standalone metadata

Standalone --version prints exactly cp 0.2.1 followed by one newline. Standalone --help starts with Usage: cp, 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.
