Tracing today's leader…
The ladderFive provenance marks — the same ◆ every score wears across the terminal
A third party ran the model.
Replicable from the harness's published prompts and scoring code. The strongest mark a score can wear.
HELM · LiveBench · SWE-Bench Verified · LMArena evals
An aggregator surfaced the score.
Model card, leaderboard table, registry entry — a neutral party re-attesting a primary source.
Hugging Face · Papers with Code · model registries
The maker's own number.
System card, model card, launch post. Authoritative on the model — not independently replicated.
OpenAI system cards · Anthropic model cards · vendor blogs
A vendor re-states a rival's number.
Launch-post comparison tables, a blog quoting a competitor's eval. Kept, attributed — and never the headline.
Demoted below first-party attribution when the headline score is selected
Extracted from prose, not re-run.
Research papers, conference talks, technical briefs. Surfaced with its source — the lowest rung, worn openly.

The pipelineFive stages, source poll → published board · runs without human hands
01Ingest
200+ sources poll on schedule — leaderboards, system cards, audited harnesses, papers.
Sources register on first detection
02Canonicalize
Aliases collapse onto one canonical model and one canonical benchmark; most-recent wins at the database layer.
One row of truth per (model, benchmark)
03Score
Per-axis manifestos define the basket. Composites are reliability-weighted percentiles, shrunk toward the median for thin samples.
Two bases, toggleable everywhere
04Verify
Every score carries its provenance mark; within-model disagreement surfaces as a band, never averaged away.
Low confidence → review, not publication
05Publish
The boards render straight from the scored view — no editorial overlay between the data and the page.
