PHILIA EcoSensory Swarm Phase SC-4 Part 2 — Written Protocol Annex v1.2: Source Independence Supplementary Interpretations (§6.0.1 ⑤)

This document is the Written Protocol Annex v1.2 for PHILIA EcoSensory Swarm Phase SC-4 Part 2 substrate collection. It is supplementary to the SC-4 Pre-registration v0.7 (DOI: 10.5281/zenodo.20471179), where Annex v1.1 was included as a supporting file. The revision in v1.2 adds three supplementary interpretation clauses to §6.0.1 ⑤ Source Independence, confirmed by 5/5 Trinity AI Research Team consensus during SC-4 Part B Gate-0 audit (2026.06.02): (1) Shared hospital infrastructure (e.g., MIMIC-II) does not constitute a shared source. Datasets published independently with distinct curators, platforms, and DOIs are treated as independent sources. (2) Spatially distinct biosignal channels from different electrode/anatomical sites are treated as physically distinct quantities, even if the measurement unit is identical (e.g., surface EMG channels from different muscle groups). (3) IMU vector components (X/Y/Z axes), multi-lead ECG, and multi-channel EEG are recognized as orthogonal physical quantities and treated as individual substrates. Empirically confirmed by distinct AC1 and MSE values per axis/channel. All other content is identical to Annex v1.1. MSE regime remains a descriptive diagnostic only and must not enter substrate adoption decisions (Risk #2).
