How each client answered
| Client | Version | Verdict | What happened |
|---|---|---|---|
| curl | ngtcp2/1.11.0 | Pass | Responded correctly: closed with FRAME_ENCODING_ERROR, which is the code §12.4 requires for a frame of unknown type. |
| quinn | noq fork | Pass | Responded correctly: closed with FRAME_ENCODING_ERROR, which is the code §12.4 requires for a frame of unknown type. |
| aioquic | 1.3.0 | Pass | Responded correctly: closed with FRAME_ENCODING_ERROR, which is the code §12.4 requires for a frame of unknown type. |
| chromium | build 1223 | Pass | Responded correctly: closed with FRAME_ENCODING_ERROR, which is the code §12.4 requires for a frame of unknown type. |
| quic-go | quic-go v0.61.0 | Inconclusive | The client completed its request and then said nothing further before the window closed. A rejection whose CONNECTION_CLOSE was lost cannot be told apart from a client that never objected: QUIC re-sends that frame only in answer to an incoming packet, so one that goes missing is simply never seen. |
| quiche | 0.30.0 | Pass | Responded correctly: closed with FRAME_ENCODING_ERROR, which is the code §12.4 requires for a frame of unknown type. |
| neqo | 0.31.1 | Fail | rejected the unknown frame type with INTERNAL_ERROR, where RFC 9000 §12.4 requires FRAME_ENCODING_ERROR. The violation was detected; the code reported is wrong. |
What the clause requires
Close the connection with FRAME_ENCODING_ERROR. Unlike HTTP/3, QUIC reserves no ignorable frame types — §12.4 makes an unknown frame a connection error, so ignoring it is the failure here.
