Residual self-jurisdiction is what stops coercion from expanding to fill the space around it. When one power is overridden — movement restricted, a decision made by a surrogate — the temptation is to absorb every adjacent choice for convenience, until a person restrained for one reason has been managed in all things. The principle refuses that: authority is taken only where the coercive purpose genuinely requires it, and everything else stays with the participant. It is the bounded-override discipline seen from the participant’s side, and it pairs with the recognition that reduced decision authority is never zero signal authority — a constrained participant still tells the ecology what they fear, want, and refuse. See coercion does not acquire the person.
Residual self-jurisdiction
The principle that every domain a coercive purpose does not actually require remains under the participant's own authority. When a specific power is overridden for a specific reason, all the rest — clothing, food, communication, relationships, spiritual practice, routines, participation in decisions — stays theirs, so restraint cannot spread past its justification simply because one major liberty was removed.
