K₄ LIGHT + GRADE LOCK the same hour, light direction, color temperature and camera grade in every frame (soft daylight with warm sun on the canopy). ¬K₄ = light jump / grade mismatch / shadow‑direction flip. K₅ POSE/GAZE/VIEW VARIATION exactly four frames, each a DISTINCT appropriate pose+gaze+framing (standing turn‑back / seated lean‑in / seated gaze‑away hand‑in‑hair / seated cheek‑on‑hand), each interacting naturally with scene furniture (hand on chair or table); no duplicate views. ¬K₅ = duplicate poses / floating hands / inappropriate pose / wrong frame count. η HONEST PORTRAIT natural skin, consistent fabric wrinkles, prop continuity, phone‑portrait realism. FORBIDDEN = face drift · outfit change · location jump · light jump · duplicate poses · wrong frame count · floating contact · studio look
