Architecture principles #

01

Longitudinal over episodic

DT4H models adaptive trajectories instead of isolated snapshots.

02

Calibration over static scoring

Confidence and state evolve continuously through evidence.

03

Execution-aware intelligence

SETPOINT outcomes become new evidence for Twin recalibration.

04

Governed infrastructure

DT4H remains bounded as adaptive infrastructure support.
