Door

Internal singularities arising from anomalous external contact, detectable only within the fruit interior. The intrinsic data axiom A5, door definitions, and Theorems B, C, G.

Theorem B — Finiteness of Doors

The number of door nodes is bounded by theta times the volume divided by the threshold. A direct energy-budget argument.

Theorem G — Door Stability

Under weight perturbation, doors with sufficient margin above the threshold are stable — only the epsilon-boundary layer may change.
