FuelBoard Contributor 7dbb3d1a15 More info sheet: float the "Copied" capsule over the address row, not the map 
The confirmation belongs to the address row, so hovering it over the map read as
belonging to the map. It now overlays the address row itself, horizontally centred
on the address line, as .overlay(alignment: .center) on the row with
allowsHitTesting(false) still keeping the row tappable through the capsule.

Verified: with the capsule up, the OCR box sits at y 1189-1231 inside the address
band (map bottom is 1075), the tint blob is centred at x 602.5 against a screen
centre of 603, the row's ink runs outside the capsule footprint are byte-identical
to the idle frame, and a real tap on the capsule's own footprint still copies.

FuelBoard Contributor 6e534ed5b7 More info sheet: float the "Copied" capsule and put the copy glyph on the address line 
The address row is back to a single line: the copy glyph now sits on the address
line itself (trailing, plain glyph — the confirmation says it elsewhere), and the
always-reserved second line is gone.

The "Copied" confirmation is now a green-tinted capsule that floats over the
bottom of the map, directly above the address and horizontally centred. It is an
overlay with allowsHitTesting(false), so nothing reflows while it is up (verified:
the address row's ink, column for column, does not move) and the map's tap target
stays live underneath (verified: tapping where the capsule floats still opens
Apple Maps). A material base keeps it legible against map tiles, where a 14% wash
alone — the notice-capsule recipe — disappears. Timing is unchanged: 2s, then
fades, with the success haptic on copy.

FuelBoard Contributor 73db893f4f More info sheet: drop the hairline between the map and the address 
The map already reads as its own block, so the row separator below it only
added clutter. Removed with .listRowSeparator(.hidden, edges: .bottom) on the map
row, leaving the Address/Distance and Distance/actions hairlines in place.
 2026-10-14 13:16:19 +01:00
FuelBoard Contributor 7da09928ca More info sheet: one card for the map, address, distance and the two actions 
The map, the address, the distance, any notices and the Directions/Report issue
row now share a single section, in that order, with the buttons as the last row.
The list's own row hairlines separate them (inset like Address/Distance), so no
hand-rolled Divider is added — that would double the line.

The map loses .listRowInsets(EdgeInsets()) so it sits inset inside the card with
its rounded corners, aligned with the hairlines and text rather than butting the
card edges.

Directions/Report issue keep .buttonStyle(.borderless); verified with real
simulated taps in the merged card that each fires alone.
 2026-10-14 12:48:33 +01:00
FuelBoard Contributor 666d59c483 More info sheet: give each action button its own tap target 
Directions and Report issue both fired on any tap inside their row: with the
default button style a List row has a single row-wide tap target, so tapping
one button triggered the other's action too (tapping Report issue opened Apple
Maps, and tapping Directions showed the report alert).

`.buttonStyle(.borderless)` gives each button its own hit area over its
half-row frame. Verified with real simulated taps on both buttons.
 2026-10-14 12:25:16 +01:00
FuelBoard Contributor 311118f0fa Add a DEBUG screen-marker hook so Simulator taps can be verified 
`-qaScreenMarker` paints the screen flat magenta, which lets a macOS capture
locate the device-screen rectangle exactly and map simulator-screenshot pixels
to click coordinates. `simctl` cannot drive taps and the project has no UI-test
target, so this is the only way to test real touch behaviour on the sheet.
Guarded by #if DEBUG, exactly like the existing -qaCopyPostcode hook.
 2026-10-14 12:25:16 +01:00
FuelBoard Contributor 1b2bdd46ea More info sheet: give the two station actions their own card below the map 
Sharing the map's section made the buttons read as part of the map card and
the map tap target. They now sit in their own section, rendering as a
separate card directly beneath the map.
 2026-10-14 12:07:54 +01:00
FuelBoard Contributor 6983fa83cc More info sheet: put Directions and Report issue on one line under the map 
The two station actions now sit together directly beneath the map card, each
taking half the width, instead of being two separate rows at the foot of the
sheet.
 2026-10-14 11:52:41 +01:00
FuelBoard Contributor 68139e6690 More info sheet: overlay the map tap target, move the copy line below the address 
The map tap target is now an OVERLAY button on top of the Map. A Map wrapped
in a Button inside a List row never received the touch, so the first attempt
left the card inert. The Map stays non-interactive and the overlay owns an
explicit rounded-rect content shape.

The copy glyph and its Copied confirmation move onto their own always-present
second line, so the confirmation can no longer reflow the address above it.
Verified: the address line's ink-pixel runs are identical with and without
the confirmation.

FuelBoard Contributor 6f177837a5 Stop Approx. distances beside routed values; add Best Value alert mode 
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.

FuelBoard Contributor 2a2823c180 Accurate distances toggle, Approx. distance markers, and Closest-mode speedup 
Distance confidence
- Every distance surface takes the figure AND its "Approx." marker from one
  FuelStore.stationDistanceDisplay call (station rows, detail sheet, widget,
  Live Activity, watch, Siri), so a surface can never mark one figure approximate
  while showing a routed one. Radius filters and Closest ordering test that same
  displayed distance, so no row can read a distance outside the radius that
  filtered it (the reported "14.6 mi inside a 10-mile list").

Accurate distances (Settings -> Distances, default off)
- Off: the browse layer serves the straight line, marked Approx., for every row,
  so two installs agree to the metre and the app makes no route requests at all.
- On: routed distances for the whole search area, unmarked, served only from a
  COMPLETE set anchored within 600 m — a partial fill reverts every row at once
  rather than mixing road and straight-line bases.
- Best Value maths sits deliberately outside the toggle: it keeps using measured
  road routes and its own confidence marking, so money figures never move with
  the switch.
- Fills run only while the toggle is on and the app is frontmost; capacity raised
  to 600 stations per pass; completeness tolerates pins Apple Maps has no route
  for, which otherwise left an area permanently incomplete and the whole list
  stuck on estimates.

Performance (the reported slowdown switching to Closest / launching with it)
- FuelStore.accurateDistancesEnabled was a UserDefaults(suiteName:) read per
  call: a synchronous cfprefsd round-trip measured at ~1.9 us, ~200k calls per
  Closest sort. Memoised, with the setter keeping it in step.
- Both keyed sorts decorate their keys — one distance per station, carried as an
  index instead of copying whole stations into the decorated array — and the
  comparison baseline plus per-station journeys now come from ONE pass instead of
  two full scans per tab. The Stations tab also reuses its single sorted list for
  the count and the TOP badge instead of sorting the country three times.
- Measured on iPhone SE (7,914-station Closest pool): sort 36.6 ms -> 17.1 ms per
  list, Cheapest 6 ms, Best Value 11 ms.
- DEBUG probes: FB_PERF list timing, FB_PERF_BENCH toggle-read benchmark, and
  FB_DIST_FOCUS now reports the served value, marker and mode (and re-prints when
  a fill lands). FB_ACCURATE_DISTANCES / FB_SORT_MODE env forms for devices, where
  devicectl eats a leading-dash argument.

Tests: 198, 0 failures. Device and simulator Debug builds green.

FuelBoard Contributor d5e7ff737f Best Value page: the button says Continue in both states 
The declined state had its own "Not now" label, on the theory that declining
should read as a decision rather than a skip. In practice the toggle above it
already shows which answer is being given, so the second label only added a
second thing to read. The label is now an unconditional Continue for both
states, which also let primaryTitle drop the settings value it no longer
consulted.

Nothing else about the page changed: the toggle still hides the sliders when
off, the "can be turned on in Settings" note still appears when declined, and
the settings still save as the controls move.

Verified on the simulator (OCR of the rendered screens): the announcement page,
and the onboarding page with the toggle both off and on, all show Continue as
the bottom button. No "Not now" remains in the app's source. 180 tests,
0 failures.

FuelBoard Contributor bfa9209d68 Best Value: announce the page to existing users, once per announcement version 
Users who finished onboarding before Best Value existed are "completed, not
fresh" forever, so the first-run gate never fires again for them and the feature
stayed invisible unless they went looking in Settings. They now get the Best
Value page on its own, once per announcement version — deliberately NOT a replay
of the onboarding flow, which would re-run permission pages they answered long
ago and has no skip.

- FuelStore: "fuelboard.bestValueIntroVersion", stored through the same
  saveString/loadString path as the onboarding flag and compared against a
  CODE-SIDE "currentBestValueIntroVersion". Deliberately not
  CFBundleShortVersionString: keying on the bundle version would re-announce on
  every bugfix release. Bump the constant to re-announce on purpose.
- FuelStore.shouldAnnounceBestValue(settings:hasSeen:onboardingDue:isSuppressed:)
  holds the rule, with every fact injectable so it is unit-tested instead of
  being driven through a simulator. It declines when onboarding is due or on
  screen, when this announcement version has been seen, and when the user has
  already configured Best Value themselves.
- BestValueAnnouncementHost wraps the app's content and owns the presentation
  state, so ContentView's change is a single wrapper and the whole feature lives
  in the new file. It reloads the stored settings on dismiss, because the page
  writes straight to the store rather than through ContentView's binding.
- The page is now ONE view, BestValueIntroContent, used by first-run onboarding
  (page 5 of 6) and by the announcement, so the copy, the sliders and the
  "declining is a decision" rule cannot drift. OnboardingView drops its private
  duplicate of the page, its bindings and its read-outs, and finish() marks the
  announcement seen so a new user never sees the page twice.

QA hooks (DEBUG): -showBestValueIntro forces the announcement, and -skipOnboarding
suppresses it. Worth knowing now that a returning install announces on a PLAIN
launch, so tab screenshots need -skipOnboarding.

Verified on the simulator (OCR of the rendered screens): a plain launch of an
install that has completed onboarding shows the single announcement page — Best
Value title, explanation, "Turn on Best Value", the "Settings, under Fuel
Savings" note and a "Not now" button, with no page dots; -skipOnboarding shows
no cover at all; -showBestValueIntro forces it. 180 tests, 0 failures (8 new).

FuelBoard Contributor a69ee14e07 Onboarding: add a Best Value page before the final screen 
New page 5 of 6, sitting between "Prices, ready when you are" and "You're all
set":

- Explains the feature: the cheapest pump isn't always the cheapest fill-up.
- Asks whether to switch it on, with a toggle.
- Switched ON, it asks for the two figures the ranking needs — average fuel
  economy and typical fill-up — using exactly the Settings slider pattern
  (read-out above a slider, £/Litres picker, no text entry anywhere).
- Switched OFF, it says where to switch Best Value on later ("Settings, under
  Fuel Savings") instead of showing controls the user has just declined, and
  the button reads "Not now" rather than "Continue" so declining reads as a
  decision.

Chosen figures are written to the store as the controls move — the same
immediate-persist rule as Settings — so swiping past the page cannot lose a
choice. ContentView now reloads the stored savings settings when onboarding
dismisses: onboarding is a full-screen cover writing straight to the store
rather than through ContentView's binding, so without the reload the choice
would not take effect until the next launch.

QA hooks (DEBUG only, alongside -tab / -skipOnboarding): -showOnboarding forces
the cover up (the app-group onboarding flag survives an app delete, so a
reinstall alone won't bring it back), -onboardingPage N opens straight on a
page, -onboardingBestValue on|off forces the page's choice.

Verified on the simulator: with the toggle off the page shows the title,
explanation, toggle, the "set it up in Settings" note and a "Not now" button;
with it on it shows the MPG slider (45 MPG), the £/Litres picker, the fill-up
slider (£40), the "change these in Settings" note and "Continue". Page 5 is
still "You're all set". Checked on an iPhone 17 Pro and on an iPhone SE (3rd
gen) screen — nothing clips on the small one.

172 tests, 0 failures.

FuelBoard Contributor f1d9e9591d Settings: Fuel Savings moves to the first section 
It was the third block in the List (after Units and Tap action), so the feature's
own controls — and the MPG/fill-up figures that drive the Best Value ranking —
sat below unrelated settings. The section (header, toggle, sliders, footer) is now
the first thing in the List; Units and Tap action follow in their existing order,
unchanged.

The move is a pure reorder: no copy, no binding, no gating changed. The section
still greys its controls out when Best Value is switched off, and the footer
narrative is unchanged.

Verified on the simulator: Settings opens with Fuel Savings -> Best Value ->
Average fuel economy / 45 MPG, with Units and Tap action below.
 2026-10-11 20:20:37 +01:00
FuelBoard Contributor d348157a45 Best Value: rename the remaining user-facing copy, hide the sheet section when off 
Following the sort-segment rename, the rest of the user-facing "Worth the Drive"
copy moves to "Best Value".

- Settings: the toggle is now just "Best Value" (was "Enable Worth the Drive"),
  and the narrative footer opens "Best Value estimates fuel cost only, …".
- More info sheet: the section header is "Best Value" (was "Worth the drive?"),
  and the section itself is now conditional. `fuelSavings` is nil whenever the
  feature is off — `savingsLookup` returns nil when it is not configured — so
  the heading is never left dangling over an empty section while the feature is
  disabled.
- The unavailable text reads "Best Value unavailable: …".
- Comments and doc comments that named the sort were updated so they match the
  UI instead of contradicting it.

Deliberately unchanged: the enum's raw value stays `worthTheDrive`, so stored
sort preferences and widget configs keep decoding, and FuelSavingsStatus keeps
its verdict wording ("Worth the drive" / "Not worth the drive") — that describes
a station's verdict rather than the feature, and is not shown in the UI.

Verified on the simulator: with the feature OFF the more info sheet shows
Address / Distance / Directions and no heading at all; with it ON the sheet
shows the "Best Value" section; Settings reads "Fuel Savings" / "Best Value"
with no "Enable" anywhere. 172 tests, 0 failures.
 2026-10-11 20:11:57 +01:00
FuelBoard Contributor 801f969644 Stations sort: "Worth the Drive" segment is now "Best Value" 
The third sort segment, the caption line it drives on the Stations tab, and the
Settings sentence about sorting now read "Best Value" — that is
SortMode.worthTheDrive.displayName plus the two copy sites that name the sort.

The feature that backs it keeps the name "Worth the Drive": the Settings toggle
("Enable Worth the Drive"), the Fuel Savings section header and footer, the sheet
header "Worth the drive?", the "Worth the Drive unavailable: …" text and
FuelSavingsStatus.worthTheDrive's own wording are all unchanged.

The enum's raw value stays `worthTheDrive`, so stored sort preferences and widget
configs keep decoding — only the label moved.

3 new tests pin the three sort names, the stability of the raw values, and the
fact that the feature's own wording did not change (172 total, 0 failures).

Verified on the simulator: the Stations segmented control reads
Closest | Cheapest | Best Value.
 2026-10-11 20:01:32 +01:00
FuelBoard Contributor 79c012b405 More info sheet: drop the Name row — the header already shows it 
The sheet's header (navigationTitle, .inline) shows the station name, and the
address row no longer leads with the name either, so the Name row restated the
header immediately above the address. The section now opens straight with
Address; distance, Worth the drive and the buttons are untouched.

Verified on the simulator: the sheet reads "Sainsbury's Halifax" in the header
with rows "Address / WADE STREET, HX1 1SB" and "Distance / 0.5 mi", and no Name
row. No other surface in the app prints a Name row.
 2026-10-11 19:40:11 +01:00
FuelBoard Contributor bb053de8b1 Listing rows: verdict text hugs its icon, and the address stops repeating the name 
Two things the listing row was saying twice, or too loosely.

- The verdict capsule used a Label, and a Label lays its icon and title out
  across the width it is given: in a listing row that left 22pt of empty space
  between the symbol and "Save £1.07 after travel". It is now an HStack with
  an explicit 3pt spacing (5pt in the detail sheet), so the text sits beside its
  icon and the capsule background hugs the pair. Measured on the same row: the
  capsule text moved x 412 -> 341 and the pill 270-831 -> 270-691.

- The address line printed the station name a second time. The official Fuel
  Finder address field usually opens with the station's own name ("CHIDSWELL
  SERVICE STATION, LEEDS ROAD, DEWSBURY, WF12 7QW" for "Jet Chidswell"): 14% of
  the dump's addresses start with the exact name, and 13% also end with the
  postcode the row appended again. StationAddressLine (new, in Shared/, so the
  row and the detail sheet share one rule) drops a leading repeat of the name
  and writes the postcode exactly once.

The rules are deliberately conservative: a leading segment carrying a house
number is a real street address and is left alone ("41 ANNACLOY RD ANNACLOY"),
and a partial-word match ("Jet" against "JETSON FILLING STATION") never cuts
into a word. 14 new tests (169 total, 0 failures) pin the shapes found in the
real dump as well as the examples above.

Verified on the simulator: the first listing row's second line went from
"CHIDSWELL SERVICE STA..." to "LEEDS ROAD, DEWSBURY...", and the detail sheet
reads "Sainsbury's Halifax / WADE STREET, HX1 1SB".
 2026-10-11 19:33:26 +01:00
FuelBoard Contributor 85f601fffd Fuel Savings: the feature's own settings grey out when it is switched off 
With "Enable Worth the Drive" off, the MPG slider, the fill-up unit picker
and the fill-up slider stayed live — editable settings for a switched-off
feature. They now sit in a Group disabled by `enabled`, so they grey out but
stay on screen and keep their values (the same rule as the distance picker
in Closest mode), and re-enabling restores exactly what was there.

The surfaces that USE the feature were already gated on `isConfigured`
(which includes `enabled`), so the in-list fill-up control and the Worth the
Drive sort option still disappear entirely rather than greying out.

Verified on the simulator with the toggle off vs forced on: the MPG slider
row and the unit picker row both measurably dim — MPG row mean RGB
33.06/35.62/39.49 off vs 37.61/42.70/48.43 on; picker 40.00/40.00/42.62 vs
53.35/53.36/56.82 — while the toggle row itself changes as expected
(54.85/64.77/58.96 with the switch on).
 2026-10-11 19:15:26 +01:00
FuelBoard Contributor cf3abb3fa7 Fuel Savings: MPG and fill-up are sliders, not typed fields 
The two Fuel Savings figures and the in-list fill-up control were text
fields. A typed figure could sit outside the slider's own bounds, so the
control and the number it claimed to show could disagree, and the decimal
pad needed a Done button to escape.

- Settings: "Average fuel economy" and "Typical fill-up" are now sliders
  with a read-out ("45 MPG", "£40" / "40 L") in place of the field. The
  warning copy reads "Set a realistic..." rather than "Enter...".
- FuelSavingsAdjustmentView (shared by the Stations Worth-the-Drive header
  and the Favourites tab) drops its text field and gains the same read-out;
  the typed-value machinery and the -focusFillAmount QA hook go with it.
- Slider bounds live in FuelSavingsCalculator (fillAmountSliderRange/Step,
  mpgSliderRange/Step) so the Settings control and the in-list control can
  never offer different ranges, and the fill-up slider range stays inside
  the calculator's validity ceiling (asserted by test).
- Two tests pin those invariants: every slider position is a valid amount,
  and both MPG bounds are valid MPG values. 155 tests, 0 failures.
- Comments that described the removed fields were updated; the keyboard
  Done-bar plumbing is kept (no numeric field remains in the app, so it can
  no longer fire) rather than deleted, so any field added later still has an
  escape route.

Verified on the simulator: Settings shows "Average fuel economy / 45 MPG"
with no field, and the Worth-the-Drive fill-up control shows the unit picker
with a "£40" read-out and a slider. The Settings "Typical fill-up" row sits
below the fold on every simulator available here (and synthetic input cannot
scroll it), so those pixels are unverified.

FuelBoard Contributor d0a89d97d5 Worth the Drive: calculation audit + listing/detail polish 
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.

FuelBoard Contributor d7a0ecb79a Add Worth the Drive fuel savings with road-routed estimates 
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.

station is not in cache).

Live Activity Lock Screen card and island station row pick
their Link destination the same way: Maps URL for Open map,

FuelBoard Contributor ed41df46de siri: drop generic shortcut and broaden fuel-word phrases 
Siri was hit-and-miss on 'unleaded near me' (\u2018can't do that, searching
in app\u2019 fallback). The generic parameterized AppShortcut ('cheapest
${fuel}') competed with the fixed-fuel literal-word shortcuts for the same
intent, degrading NLU ranking; it was already documented as flaky. Remove it
(now 9 shortcuts, under the 10 cap) and add natural phrase variants for
unleaded/petrol ('What's the cheapest unleaded near me', 'Cheapest unleaded
near me', 'Where's the cheapest petrol'). All phrases keep .applicationName
per the iOS 26 metadata requirement. Build-verified in extract.actionsdata:
generic gone, new phrases registered.

FuelBoard Contributor 9342ccc7c9 trends: redraw lines on 7/30/90 selection 
Callers previously morphed the existing lines on a reload, so picking a new
range only glided in place. Now every range/fuel selection (the only reloads;
the sheet has no periodic refetch) replays the staggered per-series draw-in
via revealSeries(), so the lines visibly redraw left->right when the user
switches 7/30/90. Price<->vs-cheapest still morphs (pure view toggle, no
reload). Reduce Motion jump-cuts.
 2026-08-20 18:49:54 +01:00
FuelBoard Contributor 508ccc3802 trends: staggered per-series line draw-in 
The single-waterline trace-in was invisible with sparse data (2 points draw
in one step). Replace it with a per-series waterline: each station's line now
traces left->right on first appearance, series revealed 0.18s apart in a
cascade so the draw is clearly visible. Newly-added favourites get a full
reveal immediately on reload; Reduce Motion still jump-cuts. Range/mode
morphs and numeric headline transition unchanged.
 2026-08-20 18:40:09 +01:00
FuelBoard Contributor 69c3c17606 trends: animate the price-history lines (subtle, Reduce-Motion aware) 
- Reloads (range/fuel switch, Price<->vs-cheapest) now glide the existing
  lines + y-axis to the new data via withAnimation/.animation(value: mode)
  instead of snapping.
- One-time left->right trace-in on first data appearance by revealing an
  increasing prefix of each series' points (area + line stay in sync); later
  switches morph rather than re-trace.
- Headline average rolls its digits with .contentTransition(.numericText).
- All animation honours .accessibilityReduceMotion (jump-cut to final state).
Kept two-pass area/line ordering, explicit series:, bounded fill bands, and
tight chartYScale unchanged.
 2026-08-20 17:54:55 +01:00
FuelBoard Contributor 0b27d3d4f6 road distance: pin-fingerprint guard so embedded/live/cached never cross-pollute 
The road-distance cache was keyed purely by station ID with no coordinate, so
a value routed to one pin could be served for a same-ID station whose stored
coordinate came from a different source (live fetch vs bundled offline dump
vs a corrected pin), reproducing Maps mismatches.
- RoadDistanceCache now stores each routed pin (CachedRoadDistance{meters,
  lat, lng}) and roadDistanceMeters() only serves a value when the displayed
  station's coordinate matches the pinned one (within ~11 m).
- Kept the existing origin-distance staleness guard.
- Verified embedded sample data (ids y1/se1/...) never collides with real
  relay IDs, and the widget STRICT radius filter drops far-offline samples, so
  no actual leak existed in practice — this closes the theoretical stale-pin
  channel and future-proofs against coordinate fixes.
 2026-08-20 17:26:33 +01:00
FuelBoard Contributor 01517ba687 onboarding: replay on a fresh/reinstalled install, not every launch 
The keychain-first completed flag persists across reinstalls (same bundle id),
so a new install was treated as already-completed and onboarding silently
skipped while permissions still prompted. Add install identity:
- Store an install id in BOTH the app-own container defaults (wiped on
  reinstall, persists across launches) and keychain (survives reinstall).
- isFreshInstall() is true on first-ever launch or when the local id is
  missing/different from keychain (i.e. reinstalled); it seeds a fresh common
  id so the next launch of the same install is not 'fresh' again.
- shouldShowOnboarding() = not completed || fresh install -> onboarding now
  replays once per fresh/reinstall, never on ordinary launches.
Works on free SideStore (no app-group), using the app's own defaults domain
as the same-install signal.
 2026-08-20 13:12:53 +01:00
FuelBoard Contributor d73a64023f road distance: trigger at launch + foreground, fall back to saved location 
Road-distance routing previously only fired once a fresh GPS fix arrived via
the location hook/onChange. A returning user on a cold launch waited for that
fix, and if onboarding/flag issues kept tracking from starting, distances
stayed straight-line. Now:
- refreshRoadDistancesIfNeeded() uses the last saved location when the live
  fix isn't set yet, so it can run immediately.
- It's called explicitly on launch (already-onboarded branch), on foreground
  activation, and on the existing location paths.

FuelBoard Contributor 90fb3b7385 road distance: cover all in-radius stations, not just nearest 12 
Stations past the nearest-12 cutoff silently fell back to straight-line,
which explained the remaining app-vs-Apple-Maps gaps (e.g. 3.5 straight-line
vs 5.9 road). Raise the per-pass cap to 40 and route every station within a
25 km straight-line radius (covers the 15 mi max search window) so any station
the widget/Live Activity/list can show gets a real road distance.

Also harden the new cache tests against persistent keychain state across
invocations (reset in setUp) so they pass deterministically.
 2026-08-20 11:54:23 +01:00
FuelBoard Contributor 64ef260959 widget + live activity: prefer Apple-Maps road distance, computed by the app 
The widget/Live Activity showed straight-line haversine distance (0.8 mi)
while Apple Maps routes 1.8 mi. Road routing is too heavy for the widget
execution + ~40-70/day refresh budget, so the APP now computes it:

- New RoadDistanceService (app target): for the nearest 12 stations each
  pass, calls MapKit MKDirections (free, no API key, matches Apple Maps)
  and caches metres keyed by station ID.
- Cache stored in KEYCHAIN (fuelboard.roadDistances) so the widget reads it
  even on free SideStore accounts with no app-group container; only valid
  within 600 m of the location it was built from.
- Throttled: recompute max every 10 min, or when the user moves > 400 m;
  wired into the location-update hook + location onChange.
- Widget face, app station rows + Live Activity show the cached road
  distance, falling back to straight-line when absent.
- 4 new cache tests (105 total).

## StoreKit sandbox: verified working configuration and caveats
### Verified configuration
The FuelBoard consumable tip products are:
- `com.apt.fuelboard.tip099`
- `com.apt.fuelboard.tip299`
- `com.apt.fuelboard.tip499`
The app requests these exact **Product IDs** with StoreKit 2
`Product.products(for:)`; the UI names are display labels and are not used for
lookup. The app bundle ID, App Store Connect app, explicit App ID, development
team, and Sandbox Apple Account must belong to the same developer account.
Two test environments must remain distinct:
- **Local StoreKit testing:** select `/Users/apt/workspace/fuelboard/FuelBoardTips.storekit`
in Xcode, under Product > Scheme > Edit Scheme > Run > Options. This bypasses
App Store Connect and confirms the app's StoreKit loading and purchase code.
- **Apple sandbox testing:** select **None** for StoreKit Configuration, then
use Product > Run on a physical device with the development-signed build and
a Sandbox Apple Account signed in under Settings > Developer. This exercises
the real App Store Connect catalog.
The local configuration returning all three products does not prove that the
Apple sandbox catalog is ready. Conversely, a successful local run showing `$`
does not mean the App Store Connect price is USD: `Product.displayPrice` is
formatted for the active StoreKit/device storefront. Local StoreKit prices are
placeholders and do not upload to App Store Connect.
### Availability versus pricing
App Store Connect has separate controls:
- **Availability** controls the storefronts where the IAP is offered. The
verified FuelBoard configuration uses **United Kingdom only**.
- **Price schedule** may show generated prices for **175 countries and
regions**. This is expected and does not make the IAP available in all 175
storefronts; it is Apple's price conversion schedule.
The Sandbox Apple Account's App Store Country or Region must match an enabled
IAP storefront. After changing the sandbox tester's storefront, sign out and
back in under Settings > Developer so the storefront change activates.
### Important propagation/cache caveat
During sandbox diagnosis, `Product.products(for:)` completed successfully but
returned zero products with the IAP availability set to UK. Temporarily
changing one product's availability to all regions caused it to appear in the
sandbox catalog; changing it back to UK left it working. This indicates an
Apple-side catalog refresh or propagation/cache issue, not a change required in
the StoreKit code. Apple documents that product metadata changes can take up to
approximately one hour to appear in sandbox.
If an otherwise valid product returns zero products:
1. Confirm the Sandbox Apple Account belongs to the same developer team.
2. Confirm its storefront is an enabled availability region.
3. Sign out and back in to the sandbox account on the device.
4. Delete/reinstall the development build and retry with StoreKit Configuration
set to **None**.
5. If necessary, temporarily broaden one product's availability to all
regions, allow propagation, verify the product, then restore the intended
availability and allow propagation again.
Record whether the diagnostic result is **request failed**, **completed with
zero products**, or **a partial product set**. These are different failure
classes. Do not add fallback prices or change product lookup to display names.
Sandbox testing does not require prior App Review approval of the IAP. It does
require active developer membership, an active Paid Applications Agreement,
complete banking and tax information, valid product metadata and pricing, the
correct app/team association, and a matching Sandbox Apple Account.
## Hard blockers (must happen before ANY submission)

## Review risks (know before submitting)
- **Always-location (5.1.1)** — the #1 question. The feature is visible
(Alerts tab) and opt-in; the review notes above say so explicitly.
- **Always-location (5.1.1 / 2.5.4)** — the feature is visible (Alerts tab)
and opt-in; the app does not declare persistent background location mode,
and the review notes describe region monitoring/significant-change rather
than continuous tracking.
- **Reviewer outside the UK** — empty radius; mitigated by the empty-state
task above + review notes.
- **"Cheapest" claims (2.3.1)** — mitigated by the OGL/footnote task.
