Measure ONE clip of the edit as numbers instead of a picture: a frame is rendered through the clip's export path (input profile, grade LUT, secondary correction) and measured — luma percentiles (P1/P50/P99, Rec.709), mean R/G/B, green excess (G minus the mean of R and B: >0 green cast, <0 magenta), vectorscope centroid (Cb, Cr), clipped highlights and crushed shadows. `befund` says what is off in words with the number; `vorschlag.grade` is a correction computed on a sample of the source through the clip's full grade (gamma wheel master first, then exposure, temperature, tint, gain wheel) towards median luma 0.42 and no cast WITHOUT pushing highlights into clipping, with the values it expects — pass it to lab_grade_clip, then measure again. When nothing more is gained, `vorschlag.grade` is null and `grund` says why. Give clip_id (from lab_grade_clip without grade) or zeit_s (seconds on the timeline); default is the middle of the clip. Writes nothing, costs nothing.
