[{"type":"thinking","thinking":"§3 helpers compile clean. Commit this (5e-v-b first chunk: split/count/low constant helpers), then continue with the main series bound.\n\nNow the main 5e-v-b lemma.

From exists_gapCircle_radius (hZC) (hk : 1 ≤ k): ∃ R, 4k+5/2 ≤ R ∧ R ≤ 4k+3 ∧ (∀ m : ℤ, 1/4 ≤ |R/2 − m|) ∧ (∀ ρ nontrivial, 1/(16Ĉ₀(4k+9/2)) ≤ |ρ.im − R| ∨ 1 ≤ |ρ.im − R|). The bound lemma takes these as hypotheses (or obtains them via the exists inside). Take them as hypotheses for the bound lemma (cleaner).\n\nThe split of the series norm-tsum by shells — with the tsum_split_finset helper, the split into the LOW finset (‖ρ‖ ≤ 3) and the complement, then bound the complement by shell-majorants...\n\nActually — you know what, given the enormous plumbing, let me reconsider ONE more time whether there's a fundamentally cheaper route for the series bound...\n\n**The cheap-route idea**: bound ‖seriesFun s‖ on the circle NOT via the raw series but via the IDENTITY-TO-BE... circular. No.\n\n**The middle route**: bound the series via the junk-free decomposition seriesFun s = (seriesFun s − Σ_{near} m(1/(s−ρ)+1/ρ)) + Σ_{near}(...)... still needs the far part.\n\nOK — accept the full build. But simplify the shell bookkeeping: use NORM-shells with the master bound via a single generic dyadic-sum lemma applied to the zero subtype:\n\n**Generic dyadic-tail lemma**: for the zero subtype and a nonneg function f with:\n- f ρ ≤ K·2^{-j}·(1/‖γ‖-ish)... \n\nno — let me just carefully assemble.
