CHRONO-1: Leggett-Garg Temporal-Nonclassicality Witness Bound into an Authorization Nonce

Preregistered Leggett-Garg temporal-inequality witness (K3) executed on IBM Quantum hardware (ibm_fez), measured K3=1.450 (classical bound 1, ~97% of ideal quantum value), bound into an authorization nonce / ProofRecord. Device-dependent; non-invasive-measurability (clumsiness) and detection loopholes OPEN; NOT loophole-free; NOT device-independent certified randomness. Companion to the BELLWETHER series, Remnant Fieldworks Inc. (ExecutionProof Research Program).
