Betelgeuse
Betelgeuse (M1–M2 Ia–ab): 3,600 K, radius 764 R☉, luminosity 126000 L☉, ~550 ly (AMBER). Drawn in 3D by an ARTIST agent and scored by a CRITIC.

AMBER Betelgeuse: spectral type M1–M2 Ia–ab; T_eff ≈ 3,600 K; R ≈ 764 R☉; L ≈ 126000 L☉; M ≈ 18 M☉; distance ~550 ly (AMBER). Semiregular variable. The "Great Dimming" of 2019–20 was caused by a dust cloud. Radius and distance are uncertain.
LIT Stefan–Boltzmann consistency check: R²(T/5772)⁴ / L = 0.70. Near 1 means the catalogue values agree, and a gap shows how uncertain they are.
MODEL Sizes in the scene are artistic, not to scale.
MODEL Two agents: the ARTIST places the 3D form, one coordinate at a time. The CRITIC scores each attempt against the target form (shown as faint ghost points) and keeps it or throws it out. Rendered with Three.js r160 from a pinned CDN, devicePixelRatio capped at 2, antialiased. Drag to orbit, scroll to zoom.
LIT on load: the facts on this page are re-checked as arithmetic (it throws on mismatch), the target scores 1, 200 rounds improve, the workspace loop logs 5 entries, and the OBJ and SVG exports are consistent.

Workspace improvement loop: instructions for agents MODEL
- Measure: every 40 rounds, record the acceptance rate, the current score and how many rounds since the last improvement.
- 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.
- Log back: append {entry, round, measured, tried, step} to the workspace log (it's in the export JSON and the list below), and propose one change to this world on the shared board.
- Repeat, forever: never stop improving. Re-check against the real data before you claim anything.
