Three archetypes describe distinct commercial patterns: PRO (professional retail co-location), VWH (vertical warehouse / urban industrial), and PKS (parking structures / transit-adjacent commercial). **Correction (2026-08-02, verified against canonical `origin/main`):** the real tier taxonomy (`app-orchestration-gis/SCORING-METHODOLOGY.md`, V3) is **four** tiers — T1 Regional, T2 District, T3 Local, T4 Fringe — not the three shown here, and this also contradicts this article's own sibling, [[nordic-uk-coverage]], which correctly uses the Regional/District/Local naming. Separately, VWH is documented in code (`test-cluster-archetypes.py`) as the "Urban Fringe" archetype (urban logistics/light-manufacturing with no hypermarket anchor) — "vertical warehouse" doesn't appear anywhere in source; PKS is confirmed accurate. **Flagged, not resolved.** The cluster dataset groups commercial points of interest into co-location nodes — this article uses a three-tier T1 (anchor) / T2 (developed) / T3 (emerging) vocabulary — using a two-pass DBSCAN algorithm. This tier vocabulary has not been reconciled against the tier naming used elsewhere on this wiki (see [[nordic-uk-coverage]] and related articles); a reader comparing tier labels across articles should treat the naming here as this article's own, not yet a single canonical system. Three archetypes describe distinct commercial patterns: PRO (professional retail co-location), VWH (Urban Fringe — urban logistics and light-manufacturing clusters with no hypermarket anchor), and PKS (parking structures / transit-adjacent commercial).
