  "abstract": "In small collision systems strange hadrons are suppressed, and the suppression grows with the number of strange quarks. Exact strangeness conservation in a finite volume accounts for this, but when it is imposed on hadrons it leaves the $ϕ$ meson unsuppressed, contrary to observation. We impose the conservation law on the strange quarks in a causally connected cluster, before hadronization, and count separately the combinations of a strange quark with the antiquark created together with it. A pair created from the vacuum cannot form a $ϕ$, a pair created from a gluon can only if it loses its color. With one function of multiplicity, the mean number of strange quarks per cluster, the model describes kaons, $ϕ$, $Ξ$ and $Ω$ in pp and p--Pb collisions at the LHC; the data require that about half of the same-pair combinations are excluded from the $ϕ$, and reject both an unsuppressed $ϕ$ and a $ϕ$ built only from different pairs at about five standard deviations. The same-pair combinations are those that carry the spin correlation observed in $Λ\\barΛ$ production, whose dilution is thereby tied to the $ϕ$ suppression and is predicted to decrease with multiplicity",
