Interior Coherence Instrumentation Handbook: Cohort Routing Matrices, Intake Architecture, and Clinical Workflow Validation Standard Coherence Fidelity Layer (SCFL) Pilot Edition

This Handbook operationalizes the Standard Coherence Fidelity Layer (SCFL) diagnostic-to-restoration architecture for clinical use. It bridges Matrix 1 (Cohort Class Matrix — activation geometry: where coherence collapse originates and how it propagates across twelve population cohorts) and Matrix 2 (full instrument routing logic per cohort, standardized across Entry, Propagation, Support, and Termination stages).The Handbook includes: (1) a Bridge Section formalizing the Matrix 1 → Matrix 2 transformation and its falsifiability criteria; (2) twelve cohort-specific instrument routing tables spanning veteran, trauma-exposed, addiction, developmental, aging, and existential-crisis populations; (3) Instrument Class Specifications for all ten SCFL instrument classes, each defined by purpose, measurable input, expected clinical output, operating conditions, misapplication risks, and confidence limits; (4) the Souljourner Intake Workflow, a ten-question minimum-viable coherence baseline requiring only single-word, phrase, gesture, or silence responses, paired with an explicit Safety (5) a One-Page Intake Rubric for rapid clinician scoring and routing; and (6) an addendum positioning interior coherence measurement as a nascent, empirically open scientific discipline against the six characteristics of a mature science.The Handbook is explicitly scoped as a measurement and routing layer, not a standalone therapy or diagnostic instrument in the clinical sense: the coherence baseline it establishes is analogous to a structural scan, not a clinical diagnosis, and all treatment and safety planning remain the responsibility of the licensed clinician integrating the tool. Instrument state thresholds referenced throughout (Ready / Conditional / Delayed / Contraindicated) are presented as proposed architecture pending empirical validation, documented in full in a forthcoming Measurement Infrastructure companion paper. This work is part of the broader Upstream Coherence Measurement Stratum (UCMS) canon and is distinct from, though conceptually related to, The Geometry of Now, Volume IV: The Structural Coherence Instrumentation Handbook (non-biological) (DOI: 10.5281/zenodo.21271877).
