Stable contracts
Versioned APIs, typed errors, signed cursors, and deprecation windows.
Public platform documentation, policies, service status, support, and accessibility commitments.
Canonical storage responded and source health was read.
CapOrCup reads only from publication-safe projections produced by the governed reconciliation pipeline. A disconnected store produces no public records; it never falls back to fixtures, generated identities, or unclassified upstream data.
Versioned APIs, typed errors, signed cursors, and deprecation windows.
Health, readiness, source state, incidents, and SLO evidence.
WCAG-aligned navigation, interactions, semantics, and media.
CapOrCup does not flatten “true,” “projected,” “believed,” and “argued” into the same feed.
Executed agreements, official registries, notices, reports, and authorized feeds.
Neutral calculations, research, rule interpretation, and model output with versions.
Aggregated belief movement is labelled as market evidence, never an official event.
Opinion and argument stay attributed and visibly separate from neutral analysis.
Missing, stale, disputed, withheld, and unavailable are first-class states. See the methodology, source registry, and correction ledger.
