The no-network last resort (bundled real dump) now shows a tappable banner
above the tabs — 'Offline data from 15 Aug / Pull to refresh to update
prices' — so stale snapshot data is never presented as live. Banner date
comes from the dump's own data_updated stamp (FuelStore.offlineDataLabel,
ISO 8601 with/without fractional seconds). Cleared on any successful fetch.
- BundledDumpProvider.dataUpdatedStamp (JSONSerialization, app target)
- ContentView: offlineDataDate state, offlineBanner view (tip-card styling,
orange wifi.slash + arrow.clockwise, tap = force refresh), refresh()
clears/sets it, -forceOfflineDump QA launch hook (serves the dump and
skips auto-refresh so the banner stays up for captures)
- Localizable.strings: 3 keys (banner title/subtitle/a11y)
- +3 tests: OfflineDataLabelTests (101 total)
- MirrorFuelProvider: fetches CURRENT prices from raw.githubusercontent
(latest.json pointer → history/<day>.json full dump), app-group day-cache
so the ~2.8 MB dump is re-downloaded only when the mirror pushes a new day
- LiveChainProvider: full path (app refresh) GitHub → relay; focused path
(background alert checks) relay-first so alerts never pull the full dump
over mobile data; records which leg served for About + telemetry
- FuelBeacon: fire-and-forget X-Client app ping to the relay's existing
widget-diag route (zero relay changes) — attribution + cadence on-LAN,
silent skip off-LAN is the reachability datum; /stats app-hit spike =
GitHub path failing
- Bundled dump: FuelBoardDump dataset (real 2026-08-15 snapshot, 8,022
stations) + BundledDumpProvider + scripts/refresh_bundled_dump.sh —
no-network last resort replaces the demo sample set
- ContentView: About meta from the chain; catch falls back cached → bundled
→ sample
- 89 tests (6 new: chain order x4, cache decision, beacon URL); Release
build green; beacon route verified against the live relay (204 + logged)
