Model Posture
SETPOINT is a descriptive longitudinal framework for observing regulation dynamics across time. It prioritizes variability structure, recovery behavior, and stability patterns over isolated readings.
Descriptive, not diagnostic
SETPOINT describes temporal behavior of signals. It is not a disease classifier and does not provide treatment recommendations. Clinical judgment and guideline-based evaluation remain primary.
Dynamics across time
Regulation is expressed as trajectories: stability regimes, fluctuation structure, recovery patterns, and coherence over sequences of measurements.
Overclaiming
No diagnosis. No prescribing. No automation of clinical decisions. No claim of medical device behavior on this public surface.
Trajectories over snapshots
Many health metrics behave like single photographs. SETPOINT treats physiology as a dynamic process: direction, stability, and recovery matter more than a single moment.
A composite descriptive index
SPI (SETPOINT Index) is an interpretive construct derived from variability characteristics, stability structure, and recovery dynamics across sequential data. It supports pattern observation—not decision automation.
Public vs clinical posture
Public pages explain concepts. Clinical workflows (when enabled) require identity, consent, access controls, audit logs, and traceable model/version pinning.
Consistency & traceability
The framework prefers stable definitions, explicit scope, and controlled updates. When the system evolves, changes should be visible, versioned, and reviewable.
Non-claims are first-class
Safety is not only about warnings—it's about preventing misuse by defining what the system does not do. This page exists to reduce interpretive ambiguity.
What SETPOINT assumes
Physiological signals are inherently variable, context-dependent, and probabilistic. Stability is not defined as absence of fluctuation, but as coherent behavior across time. No single reading is treated as definitive.
Known misinterpretations
Common misuse includes interpreting SPI as a diagnostic label, comparing values across individuals without context, or assuming monotonic “good/bad” meaning. SPI is a pattern descriptor, not a categorical judgment.
Stability & evolution
SETPOINT definitions prioritize semantic stability. Conceptual changes, when necessary, are versioned rather than silently modified. Interpretive continuity is treated as a first-order design constraint.
Where to go
If you want a quick grounding: read SPI, then Safety. If you are a clinician: review the posture separation.
