Abstract

This deposit contains the complete pre-registration corpus (embedded in section-batch runner scripts), runner code, summary verdicts, per-study reports, figures, POC addenda, and arXiv-format manuscript for a 259-study pre-registered empirical validation campaign of a universal Internet-of-Things to large-language-model (IoT-LLM) pipeline architecture across bioelectric, kinematic, and intraoperative-surgical sensor streams. The campaign comprises approximately 271 pre-registered hypothesis-testing decision rules across twenty-one thematic sections, executed under continuous deterministic protocol (PYTHONHASHSEED=0) with zero post-hoc threshold adjustments. The campaign achieves 91. 5% SUPPORTED (248 of 271 hypotheses). The architecture under test (the *H-pipeline*) comprises a spiral-domain encoder, a privacy-mechanism-protected k-means codebook quantization layer, a large-language-model byte-pair-encoding tokenizer (tiktoken cl100kbase), a two-layer privacy composition rule, and per-cohort operating-point calibration, decomposed into twelve stages H-A through H-L. Key empirical findings: (i) 17, 999× token reduction on real MIT-BIH Arrhythmia Database electrocardiogram data (Mann-Whitney U p = 2. 23 × 10⁻¹³, bootstrap 95% confidence interval lower bound 17, 999×) ; (ii) codebook quantization is empirically privacy-bearing on real PhysioNet data — capable-adversary patient-re-identification AUC reduces by Δ = 0. 461 (from 0. 952 raw-feature baseline to 0. 491 post-codebook) ; (iii) Stage H-K kinematic privacy mechanism composition rule generalizes the pipeline to real KIMORE rehabilitation skeleton (2, 699× token reduction) and real CMU MoCap walking (299× token reduction) ; (iv) Stage H-L intraoperative clinical-advantage triple-composition (Phase XXII + XXIV + XXV) executes at 83 ms p99 end-to-end within the 100 ms generic surgical clinical-decision-support budget and 1. 15 ms p99 inner-loop within the 50 ms tight da Vinci surgical-robot control-loop budget, with workflow phase recognition AUC 0. 970, adverse-event detection AUC 0. 672, and multi-modal bioelectric-plus-kinematic fusion AUC 0. 583.
