Replace magic ASCII decimals with char literals in ascii/fnmatch/shlex predicates (e.g. `c < 48` → `c < '0'`). Byte-id-neutral: ascii params are rune, so rune<rune emission is unchanged; fnmatch/shlex compare u8 against value-preserving (<=126) rune constants. Range bounds (0/31/127), the ±32 case offset, the 128 high-bit mask, and fnmatch 0u8 sentinels stay decimal. Regenerate the three combined.ww that embed ascii (w6c, wwdump, smoke). Add functional rows pinning predicates reachable only via fnmatch ctype classes / shlex split: [[:space:]]/[[:print:]]/[[:graph:]] + the '\t' arm of [[:blank:]] (fnmatchtest), '\t'/'\n' split separators + issafe's special-char set (shlextest) — so a wrong substitution would be caught.
