Scientific Figure Loop

The artifact is a scientific figure (the rendered image + the plot.py that produces it). Each iteration generates → critiques+grades: a generator authors a rendering script and renders the figure to land the frozen <goals> message; an adversarial critic grades it 0-100 against the fixed rubrics/rubric.md and decides pass; the generator then revises against the critic's concrete findings. The loop runs until the grade clears <pass_threshold> or the budget is hit. All work happens on copies inside a sandbox; the user's data is copied in read-only and never edited.

The cast (all in this folder):

• roles/generator.md — drafts/revises plot.py, renders figure.png by running <render_cmd>, optionally grounds domain content via <lit>; writes generation_notes.md.
• roles/critic.md — the adversarial grader: re-derives each rubric axis independently, spot-checks the figure's numbers against the data, optionally lit-checks domain completeness, and emits schemas/critique.schema.json (the grade + pass + executable findings).
• rubrics/rubric.md — the fixed grading rubric (the critic never edits it).
• schemas/critique.schema.json — the one validated output.
