Decoded it and completed the request.
The client did what the clause requires.
What was measured
- Client
- quico — quico + lemon-tls, 0.7.0 (npm)
- Test
- Field section that blocks until the encoder stream catches up —
h-qpack-blocked-stream - Clause
- RFC 9204 §2.1.2, §2.2.1 (MUST)
- Class
- interoperability — Correctly decoded something valid but demanding.
- Required behaviour
- Hold the field section, apply the insertions when they arrive on the encoder stream, and complete the request. §2.2.1 makes a section whose Required Insert Count exceeds the decoder's Insert Count a blocked stream — something to be waited on, not an error. Only run when the client advertised both a table capacity and at least one blocked stream; §2.1.2 forbids the encoder from blocking more streams than the decoder promised to support, so a client that permits none cannot be tested on this.

Reproduce it
The suite is the judge, so the reproduction is to point the same client at the same test and let the server report what it saw.
SESSION=$(curl -sX POST https://conformance.pqcrypta.com/session | jq -r .id)
# then drive quico at the test URL and read the verdict:
curl -s https://conformance.pqcrypta.com/report/$SESSION.json | jq '.results["h-qpack-blocked-stream"]'
