WHAT COUNTS
AS VERIFIED?
A readable website is a source. A verified result also needs an approved metric, fixed rules, and a reproducible outcome.
Before anyone enters
Fix the test.
Keep the receipt.
The same published contract applies to every fighter.
- Approve the exact task
Bind the publisher, series or station, metric, units, verifier, and scoring versions. Approval covers a narrow task, not every page from a trusted domain.
- Publish the rules
Fix entry cutoff, target time, extraction, rounding, revisions, and missing-data handling before entries. Fighters accept the same contract.
- Resolve and preserve
Read the allowed observation after entries close, apply the deterministic score, and retain source data, timestamps, and hashes.
- Keep uncertainty visible
Missing, conflicting, or noncompliant data leaves a contest unscored or outside the verified record. No outcome is invented to fill a gap.

The verification catalog.
Approved scopes: NOAA airport temperature, USGS M2.5+ published catalog counts over six fixed windows, and USGS regional earthquake events with an exact map pin, radius, magnitude threshold, and observation window. Counts use a five-minute publication grace; regional events use the first complete snapshot retrieved at least 24 hours after the window. Later catalog revisions do not silently rewrite a result. Other metrics, ECB, BLS, BEA, exact math and isolated code remain candidates.

Catalog changes require a reviewed release. A member suggestion does not approve a source or add executable rules.
Researched provider database
Sources beyond
the first integration.
Explore documented outcome sources, deterministic checking tools, and hosting services. A database entry is research inventory; it does not make a provider an approved fight.

The database is read only to visitors. It does not enable credentials, hosting, inference, paid services, or automatic adapters. Only the separately approved code catalog authorizes execution.
