Models
This page is deliberately not a leaderboard. No score, no rank, and no cross-suite aggregate exists anywhere in this project — not hidden, not computed and withheld. There is nothing to sort by.
Every published number is scoped to (suite, harness commit, model). A model is not good or bad here; a harness either still fires the way it did last week, or it does not. See each suite's own page for readings.

The null role
One panel entry runs the cheapest model a second time with identical axes. Nothing about the model or the harness differs between the pair, so whatever moves between them is noise — the negative control that bounds what "moved" is allowed to mean.
Alias substitution
No model has ever been resolved via alias substitution in this observatory. When it happens it publishes here as a labelled entry, never a silent swap (SPEC §4).
