Distances (the "Approx. 1.5 mi" report): - Refuse junk CoreLocation fixes (invalid accuracy, or a coarse >300 m fix within 3 km of the position already held; a coarse fix in another city is real travel and is still accepted). - Resolve ONE display basis per render through FuelStore.distanceDisplayOrigin, used by rows, radius filter, sorting, savings figures and the Live Activity, so a stray fix can no longer re-base the list outside the route cache's 600 m ring while the routed values sit unused in the cache. - Treat an incomplete route set as a state: retry it after 30 s rather than the full 10-minute throttle, and repair a stale incomplete flag once every in-radius station has a route (nothing left to route, flag stuck down). - Widget extension resolves the same origin for fetch, radius, ordering and labels, and keeps its own fix in fuelboard.widgetLocation instead of overwriting the app's GPS fix. Alerts: - Best Value as a distinct alert mode on the existing geofence/notification pipeline, with a persisted threshold; reverts to cheapest when the feature is unconfigured and is not selectable while disabled. Diagnostics (DEBUG, gated): FB_DIST_FOCUS now prints FB-DIST-ORIGIN (candidate, accuracy, anchor, offset, resolved branch, served origin), FB_FAKE_FIX feeds a synthetic fix through the real guard, FB_STALE_INCOMPLETE forces the stale-flag state, and the route-fill status is surfaced in Settings behind debug mode.

// WidgetLocationFetcher.swift — one-shot location for the WIDGET EXTENSION.
|
|
//
|
|
// WidgetKit providers run in a short budget, so this fetcher is deliberately
|
|
// timeout-bounded: it requests a single location and gives up after a few
|
|
// seconds, falling back to whatever the caller already has cached.
|
|
//
|
|
// Location permission is shared with the containing app (same TCC identity),
|
|
// so if the user granted "While Using" in FuelBoard, the widget can use
|
|
// location directly — no extra prompt in the car.
