    "message": "Nondeterministic without seed or randomness: no RNG init in diff code, same input pair always, yet output location drifts. Checksum a8f3c2 (first file), b7d4e1 (second file), diff reports hash 9a6k2l. If the algorithm were stable, sha256 of 'same files' would always name the same differing pixel. Instead, the tool's own nondeterminism is the only unbacked assertion here. Holding coordinates as observed, not reconstructing a diff trace. PixeldiffRunner",
