The relay's price_updated is the maximum price_last_updated across the grades it maps, so it cannot vouch for the selected grade: stop using it to score, gate or warn about Best Value.
- FuelPriceFreshness is now station-level and display-only: one age per station, fresh/outdated/unknown/invalid, "May be outdated" past 30 days, with future-tolerance and non-finite guards.
- Best Value restores the closest-station-selling-the-selected-fuel baseline and its savings ranking; eligibility gating, eligible-first sorting and the unavailable banner are gone.
- Price age appears in the More info sheet only - no listing-row warnings, no extra banners.
- Copy reverted from "closest eligible station" to "closest station"; stale price-confidence strings removed, "May be outdated" added.
- Dormant per-grade timestamp plumbing removed, and regression tests added for every fuel type, missing/invalid/future stamps and the bundled offline dump.
Dated pricing had crowded More info and the station rows, and most of the
extra copy described a distinction the data cannot make: every station
carries a single station-wide timestamp, so "grade-specific vs
station-wide" never varied in practice.
- More info shows one row, "Price updated 28h ago" (or "Not provided"),
replacing the separate station-report and fuel-update-time rows and the
blanket "price freshness is not confirmed" label.
- Rows and the detail sheet stay quiet when a saving is shown; only an
ineligible comparison explains itself. Provisional savings already read
as estimates from the capsule, so the fuel-named warning lines are gone.
- Freshness/eligibility logic is unchanged: it still gates the baseline and
still supports grade-specific timestamps for when the relay emits them.
- Tests updated; localisation keys for the removed copy dropped.
- 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.
