Concepts

The working vocabulary.

Terms I use across the essays, defined in one place. Each page holds the canonical definition and links to where the idea gets worked out.

The Aperture Problem

Nearly everything in healthcare passes through one narrow opening. Whatever cannot fit is refused, and refused demand lands on families.

The Three Clocks

People live their health on three timescales at once. The system is built for the shortest of them.

Absorb vs. Streamline

Every prior wave of health technology made the existing channel faster. Absorbing the work is a different thing entirely.

Divergence over Thresholds

The same reading means different things on different trajectories. Alert on departure from the expected path, not a population cutoff.

The Scissors

Three supply-and-demand curves closing at once, on a schedule already set by demography.

Trajectory State Object

Not a digital twin. Not a risk score. A data architecture decision.

Member Co-Authorship

Participation on a gradient, from passive to active — because attention is not evenly distributed.

The Companion Layer

A surface that lives where people live, rather than one they have to visit.
