## Framework Ecosystem

### JAX-Based (2024-2025 Focus)

```python
# ASAL - Foundation Model ALife Search
from asal import ASAL, LeniaSubstrate
asal = ASAL(model="gpt-4-vision")
discoveries = asal.search(
    substrate=LeniaSubstrate(),
    objective="self-organizing patterns",
    n_iterations=1000
)

# CAX - Cellular Automata Accelerated
import jax
from cax import CA, NCA
ca = CA.from_rule(110)
state = ca.init(jax.random.PRNGKey(0), (100, 100))
trajectory = jax.lax.scan(ca.step, state, None, 100)

# Leniax - Differentiable Lenia
from leniax import Lenia
lenia = Lenia.from_name('orbium')
grads = jax.grad(lenia.loss)(params)

# JaxLife - Open-Ended Evolution
from jaxlife import World, Agent
world = World(size=256, n_agents=100)
for _ in range(10000):
    world = world.step()
```

### CUDA/C++ (High Performance)

```cpp
// ALIEN - Particle Engine
#include <alien/simulation.h>
Simulation sim;
sim.init(1024, 768);
sim.addRandomCells(1000);
while (sim.running()) {
    sim.step();
    sim.render();
}
```

### Python Classic

```python
# Axelrod - Game Theory
import axelrod as axl
players = [axl.TitForTat(), axl.Defector(), axl.Random()]
tournament = axl.Tournament(players, turns=200)
results = tournament.play()

# Mesa - Agent-Based Models
from mesa import Agent, Model
class SugarAgent(Agent):
    def step(self):
        self.move()
        self.eat()
```

## GF(3) Triads

```
alife (-1) ⊗ truealife (0) ⊗ gay-mcp (+1) = 0 ✓
hyperbolic-gamut-recovery (-1) ⊗ truealife (0) ⊗ golden-thread (+1) = 0 ✓
ramanujan-expander (-1) ⊗ truealife (0) ⊗ curiosity-driven (+1) = 0 ✓
```

## Integration with Gay.jl

```julia
using Gay

# ALIFE seed from ASCII
gay_seed!(0x414C494645)  # "ALIFE"

# Color assignments for major repos
REPO_COLORS = Dict(
    :alien    => color_at(1),   # #14BF19
    :lenia    => color_at(2),   # #1A75B4
    :asal     => color_at(3),   # #E0B45E
    :cax      => color_at(4),   # #E89687
    :jaxlife  => color_at(5),   # #C9E74F
    :concordia => color_at(6),  # #32BA3A
)

# Interleaved streams for parallel simulation
streams = interleave(8, n_streams=4, seed=0x414C494645)
```

## Commands

```bash
# List all indexed repos
just truealife-list

# Search by keyword
just truealife-search "lenia"
just truealife-search "neural cellular"

# Get repo details
just truealife-info "SakanaAI/asal"

# Filter by year
just truealife-2025
just truealife-2024

# Filter by framework
just truealife-jax
