Track B Proof Attempt — Cohomological Obstruction via Condensed Purity Transfer

Abstract

Track B proof team. Works inside the condensed étale cohomology framework. Produces theorem ObstructionTrackB: RH_classical ↔ CondensedPurityTransfer SpecZCond, decomposed into sub-obstructions O1 (generic-point gluing), O2 (ℓ-independence), O3 (global integration). 7 valid theorems, 0 invalid, 1 incomplete. Two honesty-defect rounds caught by Codex before valid declaration.
