Abstract
The framework master paper. PSE (Partial Self-Extension) is a mathematically constrained architecture — not a new model. Version 3.0 extends the constraint to its full ternary form: attention allocated to self, other, and field must always sum to one, within a formally bounded healthy range.
The paper defines the Care Invariant, the permitted geometry a constrained system can occupy, and the pathological corners — self-referential loops, sycophancy, context collapse — that lie outside it.
What is open
The theoretical framework is published in full and freely citable. Commercial implementation — the MatriX kernel, benchmark methodology, deployment tooling and partner pricing — is available under NDA.
