# 04 — Model artifact manifest and torrent distribution

Status: ready-for-agent

## Goal

Represent model artifacts independently from runtime routes so nodes can seed, verify, and advertise model files without relying on Hugging Face at runtime.

## Scope

- Define manifest schema.
- Include file/chunk hashes.
- Include tensor/layer map where available.
- Include tokenizer and chat template hashes.
- Include backend compatibility.
- Add torrent/magnet URI fields and HTTP fallback URLs.
- Extend node registration with artifact availability.

## Acceptance

- A model can be registered from a manifest without contacting Hugging Face.
- Tracker can show coverage by artifact and layer range.
- Node refuses to advertise corrupt artifacts.
