PHILIA OS Phase 2 — 102nd DOI Pre-registration: Probe-Profile Shape Separation of Chaos-Family Substrates from an Autoregressive Reference Panel under Multi-Probe CEI Architecture

Description This document pre-registers a confirmatory study examining whether the probe-centered CV_mean response profile (probe-profile shape) robustly separates chaos-family substrates from a 26-member autoregressive reference panel, as measured by MAD-based RMS-z distance under a multi-probe CEI architecture. The endpoint was identified through a four-stage exploratory program (E1–E4, seeds 0–169) following the null result of the 101st DOI (H-101 NOT CONFIRMED; duty-axis slope pathway closed). In exploratory E4 (seeds 160–169), the probe-profile shape representation of CV_mean response separated nose_hoover from the AR reference panel in all five held-out seeds (MAD scorer), with four-of-five agreement under the classical SD cross-check. Sandbox reanalysis further indicated that multiple chaos-family substrates (lorenz, duffing, sprott_b, chua, kuramoto, rabinovich_fabrikant, lorenz_variant, nose_hoover) exceeded the AR LOAO boundary, while a subset (lorenz96, henon, ikeda) remained inside — establishing the endpoint as a chaos-family separator rather than a nose_hoover-specific detector. The pre-registered primary hypothesis (H-102-Primary) uses nose_hoover as the confirmatory anchor case (historically the most persistent structural-inside substrate). CONFIRMED requires ≥ 4/5 seeds outside_mad AND median MAD margin > 0, in ≥ 2 of 3 valid independent confirmatory batches (Batch A: seeds 170–174, B: 175–179, C: 180–184; replacements D–F: 185–199). The confirmatory script (philia_phase2_102nd_confirmatory_v1_1.py) SHA256 is pre-declared in this addendum: 02c661a7d67b57b39cac7a721fb449935e32143182f8d41ad09a7466688a171a. No modification to the script is permitted after this registration. All exploratory seeds (0–169) are exhausted. The CEI engine parameters, probe panel {D-05, D-07, D-09, C-c1}, shape centering procedure, MAD floor (ε = 10⁻⁴), and AR reference panel (24 AR(1) + 2 AR(2) = 26 substrates) are locked. This pre-registration is part of the PHILIA-EcoSensory Swarm Phase 2 research program. Cumulative self-corrections at registration: 29 (SC#29 carried from 101st DOI).
