Framework

A minimal boundary-design method: remove catastrophic trajectories by fixing upstream constraints.

ARCHE
Initial Conditions
What must be fixed before dynamics unfold.
BOUNDARY
Non-negotiable Constraints
What the system physically refuses to allow.
IRREVERSIBLE
Structures
Where responsibility is bound across time.
The point is not to choose an optimal future, but to delete futures that must never exist.

Three rules

  1. Fix the smallest set of constraints that eliminates catastrophic outcomes.
  2. Prefer structural refusal over monitoring, tuning, or after-the-fact correction.
  3. Bind capability to accountability where exit is impossible.
