# Unravel runtime models (StrumWorks)

The separation models that **Unravel by StrumWorks** downloads, laid out exactly like
the app's model folder, and the signed catalog that lists them.

- `catalog.json` is signed with StrumWorks' Ed25519 key. Unravel checks the signature
  against keys built into the app before reading it.
- The catalog pins every download to an exact commit of this repository, and Unravel
  verifies each file's size and SHA-256 before using it.
- Separation runs entirely on the user's Mac; nothing is uploaded.

**Licences differ per model and not every model is cleared for redistribution.**
Status values used: Apache-2.0, MIT, research-only, unresolved. See [LICENSE.md](LICENSE.md) for each model's
author, source revision, receipt and status.
