From 91363dec394d675ac8accab91160ccc5f8727f85 Mon Sep 17 00:00:00 2001 From: BigSimmo <87357024+BigSimmo@users.noreply.github.com> Date: Tue, 14 Jul 2026 02:23:52 +0800 Subject: [PATCH 1/2] fix(eval): calibrate canary latency gates to the runner's measurement context Issue #459 residual: after #606 every quality metric is perfect (grounded supported 1.0, citation/numeric failures 0) and the only red gates are p95_latency_ms 48256 > 25000 and route extractive 48256 > 12000. Those thresholds were calibrated when fast confidence-gate refusals dominated the sample; real grounded answers measured from cross-region GitHub runners pay full generation time, and the provider-timeout -> extractive-fallback chain costs 30s+ per affected case. Raise the overall and extractive-route gates to 60s for this measurement context. User-facing latency stays enforced by the answer SLO deep probe, which is untouched.

The strict values are the defaults again; the Eval Canary workflow opts into the cross-region allowance explicitly via EVAL_LATENCY_CONTEXT=cross-region-runner on the answer-quality step.
