Production Safety: Why Sandboxing, Trust, and Reset Are Non-Negotiable
Why sandboxing, trust ladders, reset controls, and tripwires are mandatory before self-rewriting code touches production.
Test-Time Search & Re-Ranking: Why One Candidate Is Usually Not Enough
Why best-of-N search outperforms one-shot mutation proposals when the search space is wide and the judge is stable.

Why the orchestrator must read evidence, request one bounded mutation, verify it, and revert failure cleanly.
The Genome: Why Your Pipeline Needs a Bounded Mutation Surface
Why self-improving systems need one mutable genome, one fixed judge, and clean rollback boundaries.
