To Create a Stone with Six Birds: Emergent Geometric and Thermodynamic Regimes from a Minimal Stochastic Substrate

We study emergence of macroscopic lawfulness in a minimal stochastic substrate defined on a finite state space Z with a time-dependent micro kernel P. A closure interaction algebra composed of six primitives is specified by an enable matrix E ∈ 0, 1^ (6×6), yielding up to 36 directed actor←informant interactions that (i) rewrite and gate the micro kernel, (ii) adapt timescale τ, (iii) select coarse-graining lenses f: Z→X and packagings, and (iv) impose accounting constraints. For a given (τ, f) we construct an induced macro kernel P̂ = PX_ (τ, f) and the associated empirical endomap E_ (τ, f), and we audit multiscale behavior along a resolution ladder k = |X|. Across a manifest-defined campaign union spanning four micro sizes n ∈ 32, 64, 128, 256 (2307 runs total), combining an exhaustive ablation suite for n ≤ 128 with a computationally motivated scaling suite at n = 256, we find robust, resolution-dependent signatures reminiscent of geometry and stochastic thermodynamics, including least-action dominance, diffusion-consistent embeddings, and non-equilibrium time-asymmetry. Beyond these substrate-specific results, the Primitive Interaction Closure Algebra (PICA) provides a reusable, implementation-independent object for specifying and comparing closure mechanisms in other emergent systems.
