Peel — a self-evolving symbolic brain
Sep 2026
The question
It changes while it runs, without gradient descent
What we built
Operational knowledge changes between attempts while the system is running: an evolver proposes, a doctor diagnoses, pruning removes — each only with proof. No neural weight is updated.
What it proved
Doom: 37 changes proposed, 1 promoted. BattleZone: pruning with proof, +66% over the native rules.
What it added to the brain
- The evolver
Why it matters for defense
It changes between attempts while it runs, with no retraining. A machine that improves mid-mission, and shows its proof for every change.
