Stability is the fixing of traces, Terms, Judgements, and Observations in place so they can be revisited without drift.
Before dynamics, the system must freeze what it has. Stability ensures that the structures produced so far — traces, terms, judgements, observations, contexts — can be fixed and revisited without drift. It isolates the invariants needed before introducing Flows, Nuclei, and geometric structure.
Stability is forced before dynamics because dynamics acts on structures. If the structures Flow acts on are not stable, then Flow does not transform them coherently. Stability is not the opposite of change; it is the prerequisite for coherent change.
