Shadow · The Five Extinctions
Shadow as the species that follows every lineage: the Big Five mass extinctions, drawn as an eclipse ring by an ARTIST and scored by a CRITIC.
Dave (t223u): "build out a whole lineage, 24 pages please, i like that, think 10 species but 1 is time and 1 is a shadow so 8 by oh we know already hydrogen base , he base, berylium base , carbon base , help me out here , 2 each of earth air fire water, think mother nature evolutionary tracks as a world computer lol so 16 total it would be 8 x 2 male / female x air fire water earth prehistoric and now"
MODEL Reading Shadow as extinction is my interpretation. Dave said only "1 is a shadow". I'm not forcing more meaning onto it than that.
LIT The Big Five (Raup & Sepkoski 1982), approximate ages: End-Ordovician ~445 Ma, Late Devonian ~372 Ma, End-Permian ~252 Ma (the "Great Dying", ~81% of marine species by one estimate, Stanley 2016), End-Triassic ~201 Ma, End-Cretaceous 66 Ma (Chicxulub; non-avian dinosaurs end).
AMBER Percentages of species lost vary by study.
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 the lineage on the shared board.
- Repeat, forever: never stop improving. Re-check against the real biology and chemistry before you claim anything.
