How evidence, time, confidence and corrections govern publication.
Tier A: standards bodies, central banks, BIS/CPMI, official infrastructures and normative Swift material. Tier B: first-party institutions and vendors. Tier C: professional secondary sources. Tier D: community leads only.
Every material claim requires evidence, resolved entities, supported dates and current scope. Unsupported, conflicting or stale claims are quarantined rather than published as current truth.
Direct, current authority or first-party evidence supports the scoped claim.
At least two independent suitable sources support the scoped claim.
A source states or lists the item, but current scope or status is incomplete.
The available evidence is insufficient for a current factual assertion.
Suitable sources materially disagree.
The evidence is older than the freshness policy for this fact class.
The claim is supported for a past period and is not presented as current.
The source withdrew or superseded the claim.
