Class A · White Stars
Spectral class A (7,500–10,000 K): white. Spectral signature: strongest hydrogen Balmer lines. Rendered as a 3D star with an ARTIST and a CRITIC.

LIT Harvard/MK class A: effective temperature 7,500–10,000 K, colour white. Spectrum: strongest hydrogen Balmer lines; ~0.6% (AMBER). e.g. Vega, Sirius A, Deneb.
LIT Wien's law at a representative 8,800 K: peak λ = 2.898×10⁶ nm·K / T ≈ 329 nm.
MODEL The representative temperature and the scene are my choices.
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.
