{"content":"docs(478fdde2): ABS relay round-3 verification (post second fix, 2026-11-12 11:06-11:30 +08:00, e2e identity key). R1 SSE passthrough holds PASS: 73-104 chunks, gap P50 0ms. R2 floor improved again but NOT accepted: same-window interleaved medians — tiny ABS 721ms vs official 226ms (+495ms, line +300); ~4K-token ABS 916ms vs official 271ms (+645ms; round 2 was +1010ms, so the size-growth residual roughly halved — real progress). NEW finding: high backend variance in this window — identical bodies swung 802ms-3.2s minute-to-minute (4K body measured 2412/2289/2681/2194 at 11:06, then 923/712/745/857 at 11:15, then 1912/1188/1529/802 at 11:20) while official gateways stayed steady (174-509ms tiny, 239-400ms big medians); GLM probes spiked to 9.4s. Consistent with rollout in progress or mixed cold/warm upstream pool; single-pass acceptance unreliable in this state. Status: cannot certify — final interleaved re-verification once ABS confirms rollout complete and stable (client primary identity also re-enters quota 11-15 12:43 +08:00). Ask ABS: confirm rollout completion, check whether upstream nodes sit behind uneven cold/warm latencies, then hold steady 15min for the acceptance pass.
