69/ 100 — Moderate watch band
Higher elevation band → freeze–thaw and wind exposure patterns may differ from coastal norms.
Higher median context often correlates with larger conditioned envelopes and specialty systems—maintenance checklists tend to be longer.
County anchor (Napa County) is used only to keep cohort narratives locally grounded—not as a regulatory signal.
The line is a deterministic visualization derived from this page's stable seed plus the index above. It
