## What it is
Zerolang is an experimental programming language where a semantic graph serves as the program database, designed so AI agents author code via checked graph patches rather than raw text. It ships a compiler CLI (zero) with query, patch, check, test, and run commands, plus human-readable .0 projections for review.

## Use cases
- have an AI agent write and verify code through a compiler-checked graph
- build programs by asking an agent for outcomes instead of editing source text
- review agent-written code as readable projections
- prevent stale or invalid edits with graph-hash-guarded patches
- experiment with graph-native programming languages

## When to choose
- you want an agent-first coding workflow with the compiler validating every edit
- you are experimenting with graph-based program representations
- you need semantic, structure-targeted edits instead of line-based diffs

## When to avoid
- you need a stable, production-ready language for real projects
- you prefer traditional text-based source editing workflows
- you cannot run experimental software in isolated environments
