Check the colour CONTINUITY of a scene in the edit (Murnau): every shot is compared with the scene's reference shot (the first, or `referenz_clip_id`) at the SAME scene points — found by feature matching (ORB + homography) between the two frames, each rendered through its export path. Image-wide statistics would measure the framing, not the grade (measured: up to 5000 K apart with no grade change). At those points: white point (Kelvin and mired), lightness (L*), colour distance (ΔE). Over the threshold (8 mired, L* 4, ΔE 3) a shot gets a `befund` with the number (e.g. '150 K wärmer als die Szene (13 Mired)') and a `vorschlag.grade`: a clip grade fitted so the shot's source colours land on the reference colours, with the deviation expected afterwards. Pass it to lab_grade_clip, then run lab_look_match again. Shots without enough shared content (reverse shot, different subject) come back as `vergleichbar: false` with the reason — nothing is guessed. Scenes come from the sequence's shots (lab_shots); without them give the shots as `clip_ids`. At most 24 shots per call. Writes nothing, costs nothing.
