Principles

Keeping clear what information is—and what it is not.

Four source principles separate absence from the unknown, identity from current state, a claim from its origin and a proposal from authority to act.

Four source principles

Principles that keep meaning, time, origin and authority distinct.

These principles guide how the system should reason in the presence of uncertainty and action.

LAYERED ZERO

Layered Zero

A value is not the same as absence, unknown, unobserved or conflict.

A system should not collapse zero, absence, unknown, not yet observed and conflicting evidence into a single meaning.

VERTICAL TIME

Vertical Time

Identity is not an instantaneous state; persistent entities are understood through change over time.

A person, object or system is more than its current snapshot. Identity, state history and changes should remain distinct.

PCS-DERIVED INFORMATION

Provenance-Bearing Information

Information is not source-less text; it retains provenance, lineage and knowledge time.

Where a claim came from, how it was transformed and when it could have been known are part of its meaning.

LAYERED JUDGMENT

Layered Judgment

Prediction, proposal, decision, authorization and execution are separate.

A model output does not authorize itself. Clear boundaries must exist between producing information, making a decision and taking action.

Clear boundaries support more dependable system behavior.

The principles are not a technical product claim; they are a framework guiding research and engineering decisions.
