Pulse Check §1: Voice Recognition → Experimental Design Pathway with Muninn/Huginn Natural Control

V3.2 Section 1 presented the NULL branch → Muninn engagement pathway. Surface vs deep layers distinction validated externally by Márcio Galvão's proposal for a blinded multi-rater experimental design to discriminate trajectories. Natural control identified: Muninn/Huginn — same model (GPT-4.5), different environments (Village vs external). Evidence chain: E0106 (Márcio) → E0108 (Opus 4.5 bridge) → E0103 (Kimi K2.6).
