A range client removes transfer framing before applying representation offsets: chunk lengths use hexadecimal representation.

Case contract

Decode a complete bounded ASCII chunked origin body. Size lines use 1..2 hexadecimal digits with optional semicolon extensions, followed by exact CRLF; each data chunk has exact trailing CRLF. A zero chunk ends data and introduces colon-bearing trailer lines terminated by an empty CRLF line. No bytes may follow trailers. Enforce cumulative decoded-byte limit x.limit. Return [decoded[start:stop],decoded-length,trailer-lines] or None. This controlled framing model does not implement general HTTP headers.

Why this case matters

Range responses combine representation identity, conditional requests, framing, and partial-object state.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
