◊ A4 · the policy-brain · a Seal's mind, made real
The Brain. A bred tool stops being a lookup table.
Every Seal has a mind. Until now that mind was seven static numbers — reflexes, not thought. Here you swap it: a deterministic heuristic, a real WebLLM model running in your browser on WebGPU, or your own BYOK endpoint. Same decide(state) → {move, scores} contract; different brains behind it. Then watch the mind actually play.

one swappable contract · three engines
Heuristic
The deterministic dot-product the population breeds on. Fast, reproducible, no download.
● ready
WebLLM ◆
A real small instruct model in your browser (WebGPU). The mind, made real — no server.
● checking WebGPU…
BYOK
Same contract, inference on your own OpenAI-compatible endpoint. Key stays in your browser.
● not configured
2 · Pick the Seal, read its mind
a champion from the arena · a live decision on the board below

the decision
Press Think to run the chosen mind on this board.
3 · Watch it play — a live duel
the chosen mind drives every play, turn by turn · opponent runs the heuristic
WebLLM downloads a model once (a few hundred MB) then runs fully offline on your GPU. No WebGPU? Use BYOK or the heuristic mind — the contract is identical. The headless GA always breeds on the deterministic heuristic, so evolution stays reproducible.
