- Add FuelPriceFreshness: selected-fuel-aware eligibility plus a shared
comparison confidence, so a saving is presented as verified only when
both the candidate and the baseline pass the gate for the fuel on screen.
- Rank against the closest station with an eligible selected-fuel price
instead of the physically closest station, so a single stale neighbour
can no longer invalidate every comparison in the list. Ordinary Closest
sorting still includes every priced station.
- Keep ineligible prices visible, fall back to pump-price order, and label
Best Value unavailable when no comparison qualifies.
- Widget: same baseline and confidence path as the app.
- Tests: stale-closest baseline, alert baseline, eligibility policy,
boundary and missing-timestamp regressions.
