DESIGN.md@docs/architectureA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
DESIGN.md@docs/architecture from autonomous-ai/physical-ai-operating-system is a DESIGN.md file: the design rules coding agents follow in that repo.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Designing Autonomous — an OS for physical AI agents Autonomous is an open-source OS that thousands of physical AI devices — different sensors, actuators, and boards — can be built on without forking. This document defines the architecture and the rules that make that possible. It is grounded in two battle-tested systems: **Linux** (one kernel, every piece of hardware) and **Android** (one OS, thousands of OEM devices). ## Three load-bearing principles 1. **Organize by interface, not by vendor.** A driver lives in the *subsystem* whose capability it provides (`motion`, `vision`, `audio`), never in a vendor folder. Adding the 300th device changes one leaf, not the core. *(Linux `drivers/`.)* 2. **Two stability policies, by audience.** The contract facing skills and devices is a **frozen ABI**; the driver API behind it is **deliberately unstable and in-tree**, so when the core changes, every driver is fixed in the same commit. Out-of-tree is your problem; in-tree is ours — the flywheel that maximizes hardware support. *(Linux uapi + in-tree drivers; Android Treble vendor interface.)* …

How to install
mdr add autonomous-ai/physical-ai-operating-system/docs/architecture/DESIGN.md@sha256:64b7fc86ef329b9fThe line at the top of this page pins the label git:20260817.947aa36, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
