Index Governance

The policy set for the benchmark class — the governed indices carrying versioned methodology and an immutable track record. Slates are the tactical class and are not covered here; the class is always shown on every surface.

The two commitments everything rests on

A published value is never silently changed. Corrections go through the restatement policy, are logged forever, and appear as a second row on the same date — the original stays, flagged superseded, and the corrective row chains off it. A reader holding the old checksum still finds it in the chain and can see what it became, which is how a correction is detected without being announced.

A rule is never changed to produce a number. Methodology changes are proposed, published with backtested impact, and take effect prospectively after a 14-day consultation window.

Standing disclosure

The independent committee seat is currently vacant, so the administrator is the sole decision-maker on methodology changes. This is a real governance gap and is stated here rather than omitted.

Methodology change & consultation
What counts as a material change, the 14-day consultation window, and why changes are prospective.
Data licence & rights
What the free tier grants, what attribution it requires, and what commercial use needs.
The loop architecture
The nine scheduled agents that cultivate indices, which one may publish, and the six mechanisms that assure accuracy.
The confirm gate
What human confirmation covers — merges only — and how to read the provisional and single-venue counts.
Restatement policy
The three narrow conditions under which a published value may be corrected — and the many under which it may not.
Cessation & fallback
What happens when a benchmark cannot be computed, and why the history stays published forever.
Conflicts & the conflict wall
The wall between index operations and the trading circuit, plus standing disclosures.
Data-error playbook
Detection, triage, quarantine — and the commitment to disclose errors nobody noticed.
Complaints & challenges
How to challenge a value, a rule, or a constituent. No account required.
Settlement-reference licensing
What licensing a benchmark to settle against requires — and why publication alone does not grant it. Reading a value is free; referencing it in something that settles is not the same act.
Determination, disruption & cessation
Written for contracts rather than charts: who determines a final value, the disruption fallback ladder, and why a refusal is not a cessation.
The independent committee seat
The seven-part independence test, published before a candidate exists; the power to block rather than comment; and what the administrator may do while the seat is vacant.
Incident process
Who is paged, what they do, and what gets published when the machinery fails — as distinct from a wrong value, which is the data-error playbook.
Finding — the WETX coverage breach, August 2026
Why WETX refused for five consecutive days, the change that caused it, and what is still not established. Published because an availability figure without the incidents behind it is a number nobody can check.

Benchmark readings of prediction-market prices. Free to quote with attribution and the “as of” date. Not a forecast, not advice, and never a performance claim — where an accuracy scorecard is published it reports calibration, never returns.
