}Evidence claims
- [upstream_claim] README: official implementation of 'The Stable Signature: Rooting Watermarks in Latent Diffusion Models'; fine-tunes the LDM decoder on COCO (images containing people filtered); watermark extractor models downloadable. · locator: README intro and training notes source
- [sourced_fact] LICENSE is Creative Commons Attribution-NonCommercial 4.0 International; GitHub reports NOASSERTION; last push 2026-09-02. · locator: LICENSE header; GitHub API fields 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.
