- Station detail now separates the station's own report age from the
selected fuel's update time, so a recent station-wide report no longer
reads as an old price.
- Warning copy names the fuel and says which side is weak: the station's
price is not individually dated, or the baseline's is. The misleading
"unverified or older than 7 days" line is gone.
- Wording stays "Closest" throughout; new copy uses Unleaded / Premium /
Diesel rather than the internal grade codes.
- Localisation: new and updated keys for the added copy.
Calculation audit (brief config: 30 MPG imperial, £60 fill-up, baseline
Rontec Shelf 171.9p at 0.4 mi):
- One mile<->kilometre constant pair (kilometresPerMile 1.609344,
metresPerMile 1609.344) replaces the mixed 1609.34 / 0.621371 / 1.60934
used in the savings path. Effect ~2 ppm (invisible), but the conversions
are now auditable in one place.
- New FuelSavingsCalculationAuditTests (20 deterministic tests, no live
MKDirections) pins the brief's three stations - Tesco 170.9p/2.0 mi,
MFG Hare & Hounds 172.9p/2.8 mi, PGG Napoleon 171.9p/2.8 mi - plus
imperial-vs-US gallon, MPG and budget scaling, the break-even tolerance
boundary, the nearer-candidate clamp, route-unavailable, mixed-basis
estimates and display-rounding boundaries.
- Formula unchanged, and verified correct: fixed quantity (budget / baseline
price), pump saving, round-trip extra distance clamped at zero, travel fuel
priced at the candidate station, +/-5p break even, baseline labelled
"Closest station", sorting on the unrounded net saving. The brief's "£0.18"
for Tesco is the rounded 1 dp extra-distance caption (2.02-2.05 mi reads as
"2.0 mi"), not a rounding bug in the money.
UI (uncommitted since d7a0ecb):
- Done bar drawn in the bottom safe area from keyboard notifications:
.toolbar(placement: .keyboard) is device-dependent (present on the 15 Pro,
absent on the SE on the same iOS build).
- Favourite star in the More-info heading, wired to the same fuel-scoped
toggle as the listing rows at all three call sites.
- CHEAPEST/TOP badge moved above the price so it reads as part of it.
- Listing rows carry the real session fill-up amount instead of a hard zero
(the compact banner does not print it today; a future row layout would).
153 tests, 0 failures. Simulator and device builds succeed.
Optional Fuel Savings feature (off by default): vehicle MPG in UK imperial gallons, fill amount in pounds or litres, persisted through the existing keychain/app-group store. Ranks the WHOLE station pool by estimated net saving (fuel-price saving at each pump minus the extra return-trip driving cost) using MapKit road distances with a straight-line fallback marked (est.).
The closest station with a valid price for the selected fuel is the comparison baseline and is labelled "Closest station"; other rows read "Save £X.XX after travel" / "£X.XX worse off after travel" / "Break even". Labels live in the shared model so they are unit-tested. The TOP badge still marks the cheapest pump price and reads "CHEAPEST" when the list is ranked by net saving.
Road routing now prioritises the Worth-the-Drive candidates plus the baseline and merges cache entries instead of replacing them, so far-out stations get real routes rather than permanent straight-line estimates. Numeric fields gain a Done button above the keypad (decimalPad has no Return key); the fill-up control is hidden unless the feature is configured; Favourites shares one session fill amount with the station list. 131 tests.
Settings → Units gains a Tap station picker: Open map (default,
historic behaviour — tap opens Apple Maps directions) or More info
(tap shows a detail sheet with name, address, distance from current
location, and a Directions button). Applies to Stations and
Favourites tabs; persisted keychain-first as
fuelboard.stationTapAction. Stations footer hint follows the setting.
A history fetch that comes back empty BECAUSE the mirror is unreachable
(pointer probe failed) was only an in-sheet retry card — no global signal.
Now it also raises the red connection banner ('Check your internet
connection / Tap to try again'), so a network problem is visible on every
tab, not just inside the Trends sheet. A successful load clears the
banner (only when the banner is the connection banner — never clobbers
the offline-dump banner).
- TrendsView: onHistoryUnavailable/onHistoryRecovered closures fired from
load() (loadFailed -> unavailable; hasAnyData -> recovered);
-forceHistoryFailure QA hook (forces the unreachable state, skips
auto-refresh like the other force-* hooks)
- FavouritesView: closures threaded through the Trends sheet init
- ContentView: wires them to dataStatus (.live -> .connectionProblem on
failure; recovered clears only .connectionProblem)
- fuelboard-development skill: hook + wiring documented
Legend rows now show each station's average over the days shown
in brackets (pence; signed +X.Xp in vs-cheapest mode, matching the
list-row deltas). Footer under the key explains the figure per mode.
averagePence helper (nil for empty series) + 3 tests; -showTrends
becomes a permanent QA hook like -showKeySheet.
- Shared/FuelHistory.swift: GitHub mirror read path (latest.json pointer +
history/YYYY-MM-DD.json day files); day math (UTC noon keys), slim day decode
with the shared price band, series + deltaSeries (vs-cheapest rebase),
favourites-only app-group cache (90-day prune), parallel per-day fetches,
404/network = graph gap never error.
- FuelPriceProvider: shared priceBand + mapGrades (single source for live +
history decoding).
- FuelBoard/TrendsView.swift: line chart in the Favourites tab via toolbar
button + sheet; fuel capsule (fuels with favourites only), 7/30/90 range,
Price/vs-cheapest toggle, per-station legend, price-display style on y-axis,
empty/loading/retry states with honest copy; no widget in v1.
- Localizable.strings: Trends keys.
- 83 tests (13 history + URL regression): day math, band guard, series gaps,
delta rebasing, prune, and the appendingPathComponent regression (relative
URL resolution dropped /main — all fetches 404'd).
- Sim-verified: favourites rows + TOP/deltas; sheet controls + building-up
state with live first-snapshot date (archive has 1 day; lines render once
>=2 snapshots).
- Backlog: P1 Trends DONE (unmerged); P0 REMAINING = live provider chain +
telemetry beacon.
- FuelTypeSegmentedPicker promoted to shared (was private in StationsView)
and parameterised by fuel list so Favourites passes only fuels with favourites
- Favourites tab swaps native .segmented picker for the capsule control with
green/purple/grey fuelpump icons, matching Stations
The gold-crown header row is redundant with the list itself (rows are already
cheapest-first with a TOP badge on the first). The bottom caption about
alerts monitoring stays.
Fixing the bug where favouriting an Unleaded entry also created a Diesel
favourite. Favourites are now [FavouriteEntry] = (station, fuel) pairs:
- Starring a row pins it only for the fuel being viewed
- Favourites tabs show only fuels that actually have favourites
- Geofence monitor gives priority slots only to favourites matching the
monitored fuel
- Tests updated + new fuel-scoping test (31/31 passing)
Only fuel types that currently have at least one favourite appear as
tabs; each tab ranks that fuel's favourites cheapest-first and the
narrative (crown header, section title, cheapest-favourite explainer)
names the active fuel.
- FuelType labels: 'Unleaded (E10)'/'Premium (E5)' -> 'Unleaded'/'Premium'
- New DistanceUnit (miles/km) preference; all app + widget distances,
radii and alert text convert/display in the chosen unit
- Settings tab (4th tab): segmented miles/km picker, 'Show introduction'
replay button (onboarding moved out of Alerts tab), StoreKit tip £4.99
- ProximityMonitor + widget notifications use the chosen unit
- Tests: label expectations updated, DistanceUnit conversion + format tests
