The websocket URL pointed at the GitHub mirror because 73429df — the setsockopt crash fix zat shipped in 0.3.18 — had only ever been pushed there. It is now on tangled.org main and tagged v0.1.11 (identical content hash, no code change), so zat v0.3.20 and zlay both fetch from the forge. Conformance unchanged: 43 of 49 rows match the published baseline, the five intended reject flips hold, and the sync11/commit2-valid control still accepts.
