Documentation
Frameworks, execution loops, public-private boundaries, and prototype roadmaps for natural language programming. Lean on the plate and Euclid will insist you define your terms first.
Proposition One: two circles and the equilateral triangle they conjure, a compass, and a solid rising above the scroll. Begin with what cannot be doubted, then build only what follows.
Introduction
Sans Serif Systems is a solo-builder systems laboratory and utility bench dedicated to making AI-assisted operations predictable, verifiable, and secure. It is built for anyone who wants to build, not only those who write code. Natural language is the new API, and intent is the interface.
The philosophy rejects raw, ad-hoc, untracked prompt snippets in favor of formal execution loops, structured interfaces, and strict build ledgers. You bring the intent; the system keeps it honest.
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.
