Record Doubao reverse-alpha finding: needs black-background capture, not more content images (#26)

Browse Source

Session 2026-05-29: content-image reverse-alpha distillation fails (persistent
ghost) because the mark is never observed on a dark background (median darkest
bg over glyph pixels 58/255), so alpha is unidentifiable; no dark halo (white-
logo model is right); LaMa O is a hallucination. Gemini is clean only because
its map is the watermark on pure black (alpha=capture/255). Real unlock = black
Doubao captures (requested in #13). Shipped direction stays mask + cv2/lama.
