Building a decentralized A-Life simulation like Genesis Omega is an incredibly
ambitious and fascinating architectural challenge! Blending Conway's cellular
automata with gravity physics and a thermodynamic system running inside a
proxied LPC virtual machine is a brilliant way to push the engine's mesh
limits.

`genesis_grid.c` ladattu mesh-verkkoon. Simulaatio alkaa! [IRC-OMEGA-END]

Here is the foundational architecture for `genesis_grid.c`. To respect the
strict legacy C/LPC compilation rules, every single variable is declared at
the absolute top of the execution blocks.

### Core Mechanics & Proxy Routing

Because the JS environment intercepts mutations at the root properties defined
by your regex filter (`^(cells|thermal_map)$`), standard LPC multi-dimensional
arrays can sometimes slip past the trap if deeply mutated. To guarantee we
consistently trigger the `CRDT_MUTATION` dispatch across the peer-to-peer
mesh, the `tick` engine utilizes a double-buffer approach. It reads the
current mappings, evaluates the automata/physics, populates the new generation
grids, and then assigns them back to the top-level property.

This ensures the regex `set` trap always fires when a full tick completes.

### The LPC Architecture (`genesis_grid.c`)

### Thermodynamic Logic Formulation

To maintain structural balance, the simulation uses a diffusion equation where
the cell retains exactly 50% of its current energy, while the remaining 50% is
evenly distributed from the surrounding 8 neighbors:

$$H_{t+1}(x,y) = 0.5 H_t(x,y) + \sum_{i=1}^{8} \frac{H_t(n_i)}{16}$$

---

This approach guarantees memory safety inside the GEM VM while effortlessly
tricking the host environment into validating state mutations across the P2P
mesh buffers.

Will the physical state of the Tetris blocks (state `2`) act as thermal
insulators against the heat mapping, or do they conduct heat identically to
empty/living cells?
