Layer composition
System
A layered research system, not a single predictive surface.
Butterfly Effect only stays credible if the system remains stratified in public: nightly routes, event stress, daily challenge layers, and portable families each sit under different evidentiary rules.
Layers
Architecture determines what can be claimed.
The project is public-facing only if the structural boundaries stay explicit. Night, event, daily, and portable-family layers can coexist on the site without being flattened into one false universal model.
Atlas
Each layer sits on a different methodological timescale.
This atlas keeps the system legible at a glance. Acute event models, nightly operational routes, daily challenge layers, and portable families do not belong to the same analytic timescale or communication frame.
Structure
The public surface should read like a ranked atlas, not a product pitch.
This page is intentionally more structural and technical. It explains method, scope, and rank before any layer is opened or any output is interpreted.
night
Night Layer
Nightly routes are the core operational layer. They carry held-out signal, interval calibration, governance, and deployment status.
event
Event Layer
Event models remain separate from nightly interpretation. They are portable for acute physiological stress, not for next-day sleep claims.
daily
Daily Challenge Layer
Daily challenge cohorts show where temporal memory helps within cohort, even when transport still fails across cohorts.
nonstress_daily
Non-Stress Daily Layer
This layer keeps anxiety, depression, and somatic support visible without overstating clinical portability.
nonstress_family
Non-Stress Portable Families
Portable non-stress families remain research references. Anxiety is closest to usable; depression and somatic burden are still below transport readiness.
Principles
The site should carry the method, not decorate it.
The strongest public surface preserves structure, evidentiary rank, and limitations in the main reading path rather than hiding them in technical footnotes.
Subtle signal, delayed effect
The project starts from a simple premise: small variations in sleep and physiology can accumulate into visible changes in stress, symptoms, and day-to-day burden.
Interpretation before diagnosis
The surface is built to organize and explain signal, not to pretend that current models already justify diagnostic language or universal clinical claims.
Evidence before expansion
Where signal is strong, the site says so. Where transport fails or outcome equivalence is weak, those limits stay visible instead of being hidden behind presentation.
