This record contains the full paper “A Local-Rule Computational Model for Shape Formation and Repair” together with the complete source code, reproduction scripts, figures, raw results, dependency information, and execution instructions used for the reported experiments. The paper presents a two-dimensional lattice model in which a fixed population of simple modules forms a target structure, responds to damage, moves existing material toward missing regions, verifies whether movement commands physically succeeded, and removes unnecessary active material outside the intended shape. Each module makes bounded local decisions using nearby occupancy, target location, energy, movement support, and a sampled deficit signal. No centralized planner assigns complete repair paths. The reported experiments include: formation of a bridge-shaped target from a partial scaffold and reserve modules; recovery from a prescribed structural-damage event across 100 random-seed runs; recovery from 100 randomized connected-damage trials; component-removal tests examining migration, internal vacancy relay, boundary control, support gating, and measured-state verification. The full controller achieved exact formation and recovery in all reported fixed-damage and randomized-damage runs. The experiments also show that internal vacancy relay improves recovery when missing target cells become locally inaccessible. This work is a computational control demonstration. It is not a validated physical material model and does not include continuous mechanics, fracture, force transmission, thermal behavior, manufacturing constraints, or a physical implementation of the deficit signal.
