No numeric bar, OpenRouter baseline, or September-to-date volume is supplied, so the written trigger cannot be independently tested. Structurally, taking the maximum across several ISO weeks makes staying below a bar less likely than a single-week comparison. Late-August and early-September model releases could also produce traffic spikes, though release cadence is only an indirect signal. The 2026-09-30 vintage rule is clear, but treatment of the ISO week spanning September 28–October 4 may be ambiguous; the stated policy resolves ambiguity against the forecaster. I therefore put the event modestly below the forecaster’s 0.4.
