Observed evidence
Provider facts retain source, geography, construct, period, coverage and freshness. Different providers are not assumed to be directly comparable.
PUBLIC METHODOLOGY
Evidence before interpretation
NEXORA separates official records, normalization, derived metrics, synthesis and scenarios so every claim carries the right boundary.
Derived and composite metrics
Deterministic transformations disclose inputs and scope. Product constructs are not official statistics, universal rankings or causal estimates.
Provider status
READY means a verified public snapshot or controlled official record has passed the current quality boundary. Other states remain visible and never become production evidence.
Geography and time
City, county, CBSA, state and country remain distinct. Every record retains observation year, source period, retrieval date, snapshot date and source vintage.
Semantic missingness
Observed zero, missing, not applicable, suppressed and unavailable are different states. Government suppression flags never become measured zero.
AI interpretation
The evidence-first workspace reports sufficiency, cites configured support, and qualifies or refuses when evidence is inadequate.
Scenarios
Simulation explores trajectories under explicit assumptions and uncertainty. It is not prediction, a forecast or proof of policy impact.
Sensitivity is independent
Observed, Derived, Scenario, Demo and Unavailable describe evidence status. A separate sensitivity status controls whether content may be released.
Default deny and mosaic risk
Uncertain source, rights or reuse scope is quarantined. Multiple ordinary sources may not be combined to infer sensitive, facility-level or operational results.
Public data boundary
Public provider metadata, generic indicators and public aggregates remain separate from all private research inputs, calibration and unpublished outputs.
