flux-1.png / flux-1.jpg are real Black Forest Labs FLUX.2 [pro] Playground outputs (signed C2PA, issuer "Black Forest Labs" + trainedAlgorithmicMedia, manifests verified to contain no personal data). flux-1.jpg is the first committed JPEG-with-C2PA fixture, exercising the c2pa-python non-PNG reader path end to end. Regression tests assert both attribute to "Black Forest Labs (FLUX)". Also documents the verified finding (n=2, 2026-06-19): BFL's hosted output carries the signed C2PA manifest but NOT the open invisible-watermark DWT-DCT (decodes to degenerate all-ones, chance-level vs the FLUX reference) -- the open pixel mark is dev-inference-code-optional only. So a hosted FLUX.2 image is identified by C2PA alone, with no open-pixel fallback once C2PA is stripped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
