  "rank": "Equal-weight arithmetic mean of primary categorical temporal and pooled geographic relative deviance gains; show both. Feature-specific cohorts plus two-feature common-cohort sensitivity. Baseline form checks excluded from new-candidate ranking.",
  "fdr": "Benjamini\u2013Hochberg over all 11 primary tests, unavailable/unestimable candidates p=1. Original 28-candidate family and 10 baseline checks unchanged. Combined 39-candidate FDR sensitivity deferred until all 11 available. Placeholder p/q=1 for untested candidates is not a measured null.",
  "secondaryForms": "Same linear and restricted-cubic-spline forms as Phase5. stop_density uses log1p; heavy_rain identity. Training scaling/knots refit within each fold. No switching primary p-values.",

  "uncertainty": "Finite-sample cluster sandwich coefficient intervals; 1000 fixed-prediction block resamples, seed20261012. Permanent Phase5 authority/source-area unions. Conditional intervals omit refitting, selection and mileage uncertainty; no E8 promotion.",
  "scope": "Distinct motor-involved police-recorded injury collisions at collision locations per 100,000 motor miles. Matched counted-route collision/mileage scope for restricted sensitivity. No insurer claims, causal, residence-risk or pricing validation.",
  "vintage": "Retrospective source vintages. 2026 access-site/road snapshot and 1991\u20132020 climate normals; no as-of-2022 forecasting claim.",
  "commonCohort": "Intersection of the two admitted feature cohorts across 2022\u201323; refit baseline and each single categorical feature on same rows for temporal and all geographic folds. Descriptive robustness, not a new FDR family or joint model.",
  "untested": "Nine source/measurement gates unresolved. No outcomes are used to override F6 admission decisions.",
  "modelFailures": "Numerical/data errors stop the release for investigation; genuinely unestimable additions have p=1 and cannot be retained."
