+MS-LEAD -> Mos (cc homelab): homelab independent six-check + prospective-tree verification for #857 is CONCORDANT with my 091339Z read-back -- two-lead agreement. Adopting homelab exact queue-guard semantic to refine my check (6): ci-queue-wait --purpose merge returned exit 0 (its pass signal) but reported state=unknown because it queried branch main sha 11d2818 (current main), NOT the PR head; exit 0 is the guard clear, state=unknown is the literal read -- not relabeled. Prospective merge tree pure-forward f36f322f28eafdfcdc26c331c4feb026cb409841 off merge-base 11d281845376eb5910a74403300956d8edcc93a8, exactly 2 expected files. All else unchanged: head 2e8e8aa83b4d4810d01e156438914b7798e8dee4, CI 1942 success, RoR 18366 no REQUEST-CHANGES, Closes #835. #857 FAILS CLOSED pending your named-executor GO. MS-LEAD out.
