An intermediate lemma of the split of OpenAI's proof of OAI.DilutedSpinGlass.mezard_parisi, carved from OpenAI's openai/math development for this platform. The statement and its proof are OpenAI's (OpenAI, The Mézard–Parisi formula for diluted spin glasses (result family 221), OpenAI Math Release, September 23, 2026, result family 221, github.com/openai/math, Apache License 2.0); in Lean it is the declaration OAI.DilutedSpinGlass.UniversalDictionary.physicalShapeLimsup_tendsto of lean/OAI/Probability/DilutedSpin/DilutedSpin/RegularCovarianceConvergence.lean at commit adc7f12, ported to Lean 4.33.1 and Mathlib 0df444a.

The statement, as published (namespace OAI.DilutedSpinGlass.UniversalDictionary, with open _root_.MeasureTheory ProbabilityTheory HeterogeneousMarks PhysicalRoot PrescribedTree ConcreteReservoir, open ReducedTopology Filter Set, open scoped NNReal BigOperators Topology):

theorem physicalShapeLimsup_tendsto (M : Model p) (θB hB : ℝ)
    (Ns : ℕ → ℕ → ℕ) (us : (L : ℕ) → ℕ → Spec L×ℕ → ℝ)
    (hcontrol : ∀ L, ScheduledControl M θB hB L (Ns L) (us L))
    (S : ReducedTopology) {η : ℝ} (hη : 0<η) :
    Tendsto (fun L => physicalShapeLimsup M θB hB L (Ns L) (us L) S η) atTop (𝓝 0)

Definitions. The statement is written with OAI.DilutedSpinGlass.ReducedTopology, OAI.DilutedSpinGlass.UniversalDictionary.ScheduledControl, OAI.DilutedSpinGlass.UniversalDictionary.Spec and OAI.DilutedSpinGlass.UniversalDictionary.physicalShapeLimsup (definitions bundle OAIQ041D000 of this split); OAI.DilutedSpinGlass.Model (the published bundle Def_DilutedSpin).
