Addendum to CLOSED_RED comment 5726868200: doyle identified a second mechanism in golden #2 (35313912102), a CI job-graph defect. twohost-a started 10m39s after twohost-b because Windows n1-gate occupied its runner; missing n1-gate dependency let the Linux rendezvous expire. RCA: .spt/preserved/307/golden-35313912102/RCA-twohost-b.md. This is separate from the resume PRODUCT defect in RCA-resume-unbound.md. twohost-a mirrored failure is predicted, not yet asserted here. Hertz owns paired-job needs:[test,n1-gate]; todlando owns resume custody fix. Both must land on one gated successor before fresh shaping/golden. No same-SHA rerun, tag, or publication; r2 pool retained.
