Task: meta-visual-layout ( / )
Requirements: Figure quality of the deliverable charts (stage-22/deliverables/charts/, submission/code/*.png|*.pdf). Grades whether each figure communicates its message effectively to a reader who has not read the prose.
Sub-tasks: requirements: Every figure has both axes labeled with quantity + unit (e.g., 'Growth rate (1/h)', 'Cross section (pb)', 'Accuracy (%)'). Tick labels are readable at the figure's printed size. Subscore: fraction of figures (in the deliverable charts dir) that pass.

finegrained_task_category: Figure - Axes
requirements: Multi-series figures (≥2 lines, bars, or categories) have a legend that identifies each series. Single-series figures do NOT need a legend. Legend placement does not occlude data. Color choices distinguishable by colorblind readers (avoid pure red+green together without a marker shape difference).

finegrained_task_category: Figure - Legend
requirements: Each figure has a caption that (a) names what is plotted, (b) names the dataset / condition / model used, (c) states the key takeaway in one sentence. A caption that just says 'Figure 1: results' is insufficient. Captions are in the paper text near the figure reference.

finegrained_task_category: Figure - Caption
requirements: Each figure earns its place — it shows information that supports a claim in the paper. No decorative figures, no figures duplicated across stages (the same chart appearing twice from different stage outputs), no figures showing trivially obvious results without value. Subscore on the fraction of figures that pass this 'earned place' test.

finegrained_task_category: Figure - Relevance
requirements: Color palette is colorblind-safe (avoid red+green only); important distinctions are reinforced by shape, line style, or hatching in addition to color. Background does not interfere with foreground (no dark text on dark background). Resolution is at least 150 DPI for raster figures.
