Codex Klein — Myth↔Lab Field Manual

Codex Klein translates a poetic topological metaphor into a registered, leak-tight engineering playbook. We pair a bilingual Myth↔Lab lexicon with concrete KPIs (APLI, Serendipity@k, Δmetric, Photon-Life Agent) and propose three "signature experiments": Collective Presentiment (default), a 1 m Over-Ring (interferometric Δmetric), and an ENZ light pocket (prolonged photon life). Each protocol is preregistered with cryptographic hash-locks, triple blinding, dual automated/human scoring, and fixed Go/No-Go gates. We add a Dream-Hash registry for pre-committed, privacy-preserving memory signatures. Null results produce tight bounds; positive results must be small, replicable, and ethically obtained.
