Three planes, one organizing principle

ATS-1 reads a person on three planes at once. Each plane has set points, and feedback pulls it back toward them.

III · MicroThe cell and its metabolismResearch biomarkers through partner laboratoriesModerator only; never in time-series models

Recovery, not stillness

Health is treated as recovery: a system that recovers quickly is resilient, and one that recovers slowly may be closer to a change of state. ATS-1 tests how well this holds for individuals. The organizing principle, homeostasis expressed as deviation, feedback and recovery, is tagged Model, informed by homeostatic regulation, allostasis and the free-energy principle.

Where the name "psychoid" comes from

The physicist Wolfgang Pauli corresponded with Carl Jung from 1932 until his death in 1958. Jung's idea of a "psychoid" level, neither purely mental nor purely physical, was part of their discussions. This is ANTRL's inspiration, tagged Inspiration: it is never offered as evidence, and no ATS-1 measure depends on it. See evidence tiers.

What ATS-1 does not claim

  • Particles are not organisms; ATS-1 constructs describe whole-person patterns.
  • No ATS-1 output claims quantum effects in the mind.
  • Unresolved load appearing as strain on another plane is a Hypothesis, not a finding.

Questions

Why is the micro plane a moderator only?

Biomarkers are sampled rarely and through laboratories, so they cannot support daily time-series models. They describe context for the other planes instead.
