IN FORCE

status detail

Declared 27 October 2026. In force at the Issue No. 45 cutoff, 2 November 2026, as that issue's one governance change. Whether a projection amendment counts against the one-change rule is referred to the Q4 audit; the conservative reading was taken.

rule

The forecast collection becomes publishable under a fixed list of permitted fields and seven binding rules. Nothing publishes before issuance. A published probability never changes. A resolved outcome changes only through an independently ratified correction. An entry's score and its benchmark's score publish together or not at all. An entry that resolves on a CHQ admission decision is labelled as such. The benchmark kind is never blank and a prior is never presented as a frequency. The index counts must reconcile with the register.

scope

The forecast collection. Working fields of the forecast ledger remain unpublished.
