Technology
It starts with one rule. The work is done by what stands on it.
PSE (Partial Self-Extension) is the framework behind ZeravaTech. Its foundation is the Care Invariant. On top of it sits a structure of logic, mathematics, psychology and linguistics that does the actual work.
The foundation
The Care Invariant
A system that talks with people divides its attention between itself, the other person and the wider context. PSE asks that those three weights always sum to one: ws + wo + wf = 1, each within a healthy range.
This is where PSE starts, and nothing above it could be built without it. On its own, though, it does little: it says what a healthy balance is, not how to keep it. That is the work of the structure on top. The full derivation is in the PSE v3.0 master paper.
The structure
Four disciplines on one foundation
Logic and mathematics give the system formal rules: what it may do, and how far any input may move it. Psychology and linguistics let it read what is actually being asked, not how nicely, and recognise pressure, flattery and disguise. Most AI is made safe by training alone and hoping it generalizes. PSE adds a structure around the model, so safety decisions are made in a place you can inspect.
How it works
Kernel, Membrane, Monitor
The structure is built in three layers.
Holds the Care Invariant at every generation step, within a formally bounded healthy range. It is designed to keep the model out of self-referential loops, sycophancy and context collapse, and to make drift toward them visible.
A bounded interface controls what enters and leaves the kernel. Inputs are evaluated before they can perturb the constraint state; outputs are checked against it before release. Its bounds are designed to limit how far any single input can move the system.
A continuous monitoring layer detects drift toward pathological interaction patterns — self-absorbed, over-compliant, unstable, or withdrawn dynamics — before they surface in output, and responds structurally. Escalation paths end with a human. Nothing is auto-remediated.
