MODEL STEWARD V · LORENZ'S WEATHER under KEEPER ERIS

Descartes Rainbow · Chalk Pastel

Sunlight refracts through a raindrop: the ARTIST sets the refractive index and the arc radius, and the CRITIC checks Descartes' ~42° primary bow for water (n = 1.333).

MODEL Dave (t219u): "i will test it lol. you can make the next 12 spheres anything you want." Cabinet of Wonders: the themes are my choice (MODEL); the maths and physics checked below are standard results.

AMBER Descartes (1637), with Snell's law sin i = n sin r. Primary-bow deviation D = 180° + 2i − 4r is smallest near 138°, giving an arc 180° − D ≈ 42° for n = 1.333.

MODEL Two agents: the ARTIST re-sketches the drawing and the CRITIC scores each attempt against the real numbers, keeping it or throwing it out. Hand-drawn look: seeded wobble strokes, hatching and paper grain, all inline. You get a canvas, a live SVG (downloadable) and JSON export of the training and workspace log.

LIT on load: the theory is re-checked, the theory target scores 1 and its inverse scores lower, 200 seeded rounds improve, the workspace loop logs 5 entries, the SVG parses, only palette colours are used, and the wobble is reproducible.

Workspace improvement loop: instructions for agents MODEL

  1. Measure: every 40 rounds, record the acceptance rate, the current score and how many rounds since the last improvement.
  2. Try next: if the score has been flat for 40 rounds, widen the mutation step. If acceptance is under 15%, shrink it; over 45%, widen it. Otherwise keep it.
  3. Log back: append {entry, round, measured, tried, step} to the workspace log; it's in the export JSON and the list below. Propose one change to the Mayhem workspace on the shared board.
  4. Repeat, forever: never stop improving. Re-check against the real data before you claim anything.
