//! The `classify --pair-timeout-ms` default is **5 ms** as of v0.4.19.
//!
//! Pinned because the value is load-bearing and was chosen by measurement, not taste:
//! a 1,920-ontology two-arm sweep found 16 recoveries, 0 regressions and −15.9% wall,
//! with ΔMISSED +8 (+1.04%) and FP=0 over a 400-ontology Konclude ∪ `HermiT` net.
//! **1 ms was screened and rejected** at ΔMISSED +360 (+46.75%), so the completeness
//! cliff sits between 1 and 5 and this default should not drift downward casually.
//!
//! Only `classify` moved. `disjoint`, `individuals` and `property-values` keep their
//! own 1000 ms defaults — the sweep measured `classify`, and flipping the others
//! would be unmeasured.
