Audit of /trade-in/v2 found the FE-3/FE-4 overlay wiring (mapAnalytics/mapSources
feeding AnalyticsView/SourcesView from useEstimateHouseAnalytics,
useEstimateSellTimeSensitivity, analogs[]/actual_deals[]) already shipped in
267585e3. The remaining gap was BE-1 (#2043, merged 2026-07-02) landing real
cv/source_counts/created_at on AggregatedEstimate AFTER that wiring pass, so
v2/mappers.ts was still FE-approximating cv and duplicating a hardcoded source
label map instead of the single source-registry (#2211).
- mapSources' marketAds.kpi.cv (#2041) now prefers the real estimate.cv
(0..1 ratio from BE-1) and only falls back to the FE coefficient-of-variation
of analog prices for pre-#2043 cached estimates where cv is absent.
- adRows/dealRows source badges (#2041) now resolve via the shared
src/lib/source-registry sourceLabel() instead of a local SOURCE_LABEL map,
picking up etagi/canonical labels and staying in sync with the #2211 roster.
- AnalyticsView (#2040) KPIs/sell-time/price-history/scatterDetail were already
wired to real data with no gaps found against the issue spec.
