Substrate — a shared knowledge environment treated as an active medium: participants read from it, act through it, and write back in ways that change what others can encounter next.
Frame — a bounded unit of context or knowledge. In our current apparatus, frames are typed and can compose into larger structures; other substrate designs may use different units.
Interaction event — an observable contact between an actor and the substrate, such as retrieval, use, or write-back. Events let us study collective dynamics without claiming access to private reasoning.
Coupling — a durable relation produced when parts of the substrate are repeatedly active together. Coupling records a history of use; it does not by itself imply agreement.
Membrane — a computed, temporary boundary around a co-active region. Membranes can overlap and nest, and provide a place to read or alter the context available to a population.
Movement — observable change in active context over time. A trajectory orders those interactions into a path; across a population, trajectories make recurrence, convergence, separation, and encounter visible.
Divergence and convergence — the movement between opening a field of possibilities and settling around something usable. Whether either movement is healthy depends on the task and its stakes.
