Introduction

Sans Serif Systems is a solo-builder systems laboratory and utility bench dedicated to making AI-assisted developer operations predictable, verifiable, and secure.

Our development philosophy rejects raw, ad-hoc, untracked prompt snippets in favor of formal execution loops, structured interfaces, and strict build ledgers.

Three Operational Pillars

1. Bounded Autonomy

Limiting agent action spaces using declarative runtime schemas rather than raw system instructions.

2. Proof of Evidence

Logging verification output checks to an immutable local ledger before promoting files to main.

3. Local-First Execution

Enforcing local-first schemas, local tokenizers, and sandbox executions before hitting external networks.
