Rejected, but with error 0x106 where the specification requires 0x108. The violation was detected; the code reported is wrong.
The client did something the clause forbids, or failed to do what it requires.
What was measured
- Client
- chromium — Chromium QUICHE, build 1248
- Test
- CANCEL_PUSH for a push ID that was never promised —
h-cancel-push-unsolicited - Clause
- RFC 9114 §7.2.3 (MUST)
- Class
- correctness — Rejected something invalid, with the code the RFC names.
- Required behaviour
- Close the connection with H3_ID_ERROR. No MAX_PUSH_ID was granted, so every push ID is greater than currently allowed, and §7.2.3 requires a CANCEL_PUSH referencing one to be treated as a connection error of that type.

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=$(curl -sX POST https://conformance.pqcrypta.com/session | jq -r .id)
# then drive chromium at the test URL and read the verdict:
curl -s https://conformance.pqcrypta.com/report/$SESSION.json | jq '.results["h-cancel-push-unsolicited"]'
