This is a **cross-sectional index**, not a time series. Every locality carries its own score at a fixed reference vintage; there is no single national "current reading" the way a national indicator has one. 2Composite Construction Equal-weighted across five pillars, with a 3-of-5 floor: a locality scores on the composite once at least three pillars have a valid reading for it.

Substrate (climate resilience, mean 63.68) is the strongest, and the only pillar with a floor above 26. The composite's national mean of 51.13 sits close to the simple pillar-average midpoint, consistent with the equal-weight, 3-of-5-floor construction: a locality needs only three of five pillars to generate a composite reading, so a weak pillar like Agora pulls down the localities it covers without being smoothed away by the other four. 6Certification APN Codex Node 24100 — Certified - Current methodology: equal-weight, 3-of-5 pillar floor (interim standard) - All five pillars are independently certified and included in the composite - Inter-branch weighting study remains open, filed as separate future work
