# Equilibrium

A dynamical system's stationary state — where the dynamics leave it unchanged

Layer: Physics · Category: Primitives

## Mechanism

A [State](https://mindscape.world/scapes/bootstrap/State.md) of a dynamical system in which the system's time evolution under its own dynamics is stationary — once the system occupies the state it remains there absent external perturbation. Every dynamical system has equilibria (possibly empty), and they are classified by their response to perturbation: *stable* (small deviations decay back to the state), *unstable* (small deviations amplify away), *neutral* (deviations neither decay nor grow). Substrate property: equilibria are implied by a system's dynamics, not designed. Higher patterns test for equilibrium as a signal that a process has settled; some coordination protocols explicitly drive toward or away from a chosen equilibrium.

## Invariants

- Stationary: under its own dynamics the system does not leave the [State](https://mindscape.world/scapes/bootstrap/State.md).
- Classifiable as stable, unstable or neutral by its response to perturbation.
- Not unique: occupying this equilibrium is a fact about history, not necessity.

## Failure modes

- Transient mistaken for equilibrium: a slow-moving state is read as settled.
- Stability inferred from occupancy: the system sits here, so it is assumed to return here.
