The LAN relay is unreachable from any phone outside the developer's LAN, so
for App Store users a relay fallback was dead weight AND harmful: attempting
the private IP fires the iOS Local Network prompt on a stranger's phone and
adds a timeout before the bundled dump. GitHub raw is reachable anywhere the
relay would be, and more reliably.
- LiveChainProvider: GitHub mirror first EVERYWHERE (focused alert path no
longer relay-first); LAN relay only joins behind the hidden dev flag
fuelboard.relayFallback (Settings → Debug, keychain-first, off by default)
- MirrorFuelProvider: focused() projection replaces the relay's server-side
radius endpoint (fuel filter + within-radius + nearest-first + limit 500)
— the alert path re-checks radius/fuel itself, so behaviour is identical
- Widget: fetchFocused/fetchFuelOnly now GitHub-first via the chain (day-cache
shared through the app group); relay + widget-diag GET gated on the same
dev flag — off-LAN widgets no longer attempt local network at all
- FuelBeacon: fires only when the dev flag is on — consumers make zero
local-network attempts; /stats app-hit spike = GitHub down + dev flag on
- Onboarding: Local Network machinery removed entirely (no probe, no prompt,
no 12 s stall) — data page is now informational: prices download from the
internet, no permissions needed. Replay on cellular can no longer hang.
- Info.plist: NSLocalNetworkUsageDescription copy → optional dev-only wording
- 95 tests (6 new: relay-skip-when-disabled x2, focused prefer-mirror, mirror
focused projection x3, beacon dev-flag gate)
- 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.
