}Evidence claims
- [upstream_claim] README: Rive's lowest-level C++ runtime loads .riv files, advances state machines and animations and draws via an abstract Renderer; Apple, Android, Flutter, Unity, Unreal and web runtimes wrap it. · locator: README intro source
- [sourced_fact] Repo metadata: MIT (Copyright 2020 Rive), not archived, last push 2026-10-17. · locator: GitHub API fields; LICENSE header source
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
