https://datenvertrag.halowerk.com/v1/literal-like-pattern-witnessOverview
Decide whole-string LIKE membership for caller-supplied nonnull text, pattern and explicit escape, returning parsed tokens and a deterministic shortest-percent-span witness. Bounded Unicode scalar codepoint literal equality profile: underscore consumes exactly one codepoint, percent consumes zero or more. No ILIKE, locale/nondeterministic collation, SQL literal parser, database execution or vendor conformance assertion.
