02 · PROVENANCE

Source and review records

Every record must have a reachable official-exchange source, review date, review state and public-reference rights state. The exact source is exposed on the contract page and each expiry event.

A source-compliance self-review (publisher terms and citation practice checked source by source) was completed and archived on 2026-08-20.

03 · DATE STATUS

Confirmed and rule-based are different states

Confirmed schedule
A date explicitly present in the current contract schedule; shown without an asterisk.
Rule-based estimate
Calculated from an accepted expiry rule and marked *; holidays, notices or exchange adjustments can move the final date.

A rule-derived value must never be presented silently as confirmed. Re-open the linked official source before trading.

04 · FRESHNESS

Automated gates and review targets

  • 120 daysMinimum future coverage; current coverage ends .
  • 30 daysNear-term dates must carry an explicit review state.
  • 80%Maintenance target for confirmed dates in the next 90 days; shortfalls remain visibly estimated.
  • 90 daysMaximum record review age before the build gate alerts.

05 · CORRECTIONS

How corrections are handled

Send the page URL, field to correct, official notice URL and notice date. The accepted value stays in place until the evidence is reviewed through a traceable change; external feedback never silently overwrites it.
