pub fn graphs_ready_after_fp8_kv_cal<I>(states: I) -> boolExpand description
2026-09-25: True when every calibrating layer has frozen, which is when the
model lifts its CUDA-graph suppression (trait_impl/decode_a.rs).
Per layer: None = no calibrator, Some(false) = still inside the window,
Some(true) = frozen. True when no layer calibrates. Graphs therefore stay
eager for the whole window.
