# Stratum > The open-source, agent-first code forge — evaluation-gated merges, provenance, and agent identities, built on Cloudflare Workers. Stratum is the open-source, agent-first code forge: git hosting where every change proves itself before it merges. Humans and AI agents are both first-class identities; agents can never approve a change. Merge gates are policy-as-code in .stratum/policy.yaml and a malformed policy fails closed. It runs in layer mode over GitHub or in forge mode as the source of truth, on Cloudflare Workers. ## Documentation Sets - [Abridged documentation](https://docs.usestratum.dev/llms-small.txt): a compact version of the documentation for Stratum, with non-essential content removed - [Complete documentation](https://docs.usestratum.dev/llms-full.txt): the full documentation for Stratum ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation ## Optional - [OpenAPI specification](https://docs.usestratum.dev/openapi.yml): Complete machine-readable REST API contract - [Source repository](https://github.com/stratum-eng/stratum): AGPL-3.0-or-later, self-hostable on your own Cloudflare account
