ascii: valid, validstr, ispunct, isprint, iscntrl, isgraph, isblank, strcasecmp. bytes: hasprefix, hassuffix, rindex, rindexbyte, contains, reverse, zero. strings: rindex, sub, trimprefix, trimsuffix, ltrimbyte, rtrimbyte, trimbyte. The byte-set trim is a single-byte subset of Hare's `trim(input, exclude: rune...)`; no variadic ABI yet. path: dirname, basename, extension, join. Owned-str returns where the result isn't a borrowed view of the input (join). endian: full Hare table — be/le get/put for u16/u32/u64 plus the network-order htonu/ntohu pair extended to 32/64. lib/CLAUDE.md rewritten to reflect the post-graduation policy (tagged-union returns, owned-str returns, plan9 names, documented deviations for non-graduating modules). Makefile picks up lib/ascii and lib/fmt as wwdump_ww / w6c_ww deps so lib-only edits regenerate the affected binaries.
