Identify and unwrap a bounded caller-supplied opaque string into readable JSON,
Identify and unwrap a bounded caller-supplied opaque string into readable JSON, text or binary evidence using deterministic local rules for JWT payloads, canonical Base64/Base64URL and gzip. Ambiguous hex/Base64 representations stop in auto mode; canonical hex and Brotli can be selected only through explicit bounded hints. JWT claims are decode-only and always marked unverified.
