When a response declares a `Content-Length` that exceeds `maxSize`, the request is aborted cleanly. When a response is sent chunked (no `Content-Length`) and its body exceeds `maxSize`, it is not aborted: the interceptor ends the response early once the accumulated size reaches `maxSize`, and continued delivery from the parser triggers an internal assertion that is caught and turned into a request abort and connection tear-down.

Any application using the dump interceptor against untrusted or misbehaving upstreams is affected.\n\n### Patches\n\nUpgrade to `7.29.1` or `8.10.2`. The dump interceptor now enforces `maxSize` on both the declared and the received body size, aborting the request with a `RequestAbortedError` instead of returning a truncated response.\n\n### Workarounds\n\nNone.
