flutter_map with the same OSM tiles and no-API-key reasoning that chose osmdroid.
All four load-bearing behaviours ported and, unlike the native app's map, tested:
one polyline per segment so a pause is a real gap, render-only decimation, the
zoom clamp at OSM's max tile zoom with a short-ride fallback, and a real user
agent. Speed colouring is bucketed per run rather than per-vertex, since neither
osmdroid nor flutter_map makes per-vertex paint reasonable.
Export via share_plus, which also handles the iPad popover anchor a naive port
forgets. It passes the raw stored points, never the map's decimated path.
164 tests passing, analyze clean.

geolocator_android's ForegroundNotificationConfig raises a service with
foregroundServiceType=location and holds a wake lock for as long as the position
stream is subscribed, and the plugin declares that service in its own manifest.
That covers everything the native TrackingService used a foreground service and
a PARTIAL_WAKE_LOCK for, so flutter_foreground_task is gone -- and with it both
deprecation warnings that were recorded under T01.
Known parity gap for T27: geolocator's notification cannot carry actions, so the
native Pause/Resume buttons in the shade are not reproduced.
iOS: UIBackgroundModes plus allowBackgroundLocationUpdates keep the isolate and
the writer timer alive while updates flow. Two settings matter more than they
look -- pauseLocationUpdatesAutomatically is false because CoreLocation does not
reliably restart, and activityType is otherNavigation rather than
automotiveNavigation, which would snap fixes to the road network and silently
falsify the recorded path. Usage strings are specific, not generic.
Android deliberately does not request ACCESS_BACKGROUND_LOCATION: a foreground
service with a visible notification is exactly the supported case, and asking
would trigger the harder "Allow all the time" flow for no benefit.
T14 process-death resume is implemented and called at startup, covered by four
tests including the 111 km crash-gap guard.
Verified by building both platforms and launching on the iOS simulator: Drift
opened, Riverpod resolved, restore found no active trip, controls correct.
lib/main.dart is a harness so the pipeline can be exercised on hardware before
Phase 4 builds screens; T15 replaces it.
Phase 3 done: 145 tests passing, analyze clean.

T10 -- LocationSource abstraction plus FakeLocationSource, so the riskiest code
in the app is testable with no device. Also found that geolocator ships its own
Android foreground service with enableWakeLock, which could drop
flutter_foreground_task and both its deprecation paths; deferred to T12 since it
costs notification actions.
T11 -- the pipeline. Kotlin's unbounded Channel plus blocking-receive writer
becomes a List buffer plus a periodic Timer; Dart's event loop makes a blocking
receive unnecessary and the guarantee is unchanged, since the fix callback only
appends and returns. 24 tests.
Found a real bug in the native app while porting. restoreAfterProcessDeath says
it resumes into a new segment because the dead time is a real gap, but it calls
resumeTrip, which adopts the segment a crash left open. After a pause that is
right; after a crash nothing closed it. Points either side of the dead time then
share a segment, and computeSummary -- the authoritative pass that overwrites the
live estimate on completion -- measures straight through the gap. Reverting the
fix and running the guard shows 111,217 m of phantom distance.
Fixed via TripRepository.resumeIntoNewSegment, which closes the stale segment at
its last recorded point rather than at now, so the dead time is not billed as
ride time either. A deliberate, documented departure from parity: the code
contradicted its own comment and produced silently wrong data.
The first version of that guard passed with the bug still present -- the fixture
used pause(), which closes the segment and stops reproducing the crash. Caught
only by reverting the fix and checking the test failed.

T05 — ride_accumulator.dart with the cross-batch anchor intact (12 tests).
T06 — ride_export.dart, GPX 1.1 and GeoJSON (15 tests), parsed with real
parsers rather than substring matching.
T07 — parity harness extended to cover export byte output.
GPX and GeoJSON are byte-identical across Kotlin and Dart: same length, same
FNV hash, including the escaped hostile name and all %.7f/%.1f formatting.
Two harness bugs found and fixed while building it. String.hashCode is not
comparable across Java and Dart, so text comparison used FNV-1a instead. And a
missing jar let a failed Kotlin compile pass as a green run -- run.sh now checks
for the artifact and exits non-zero, the same failure mode as the v2 sweep that
hid a compile error behind /dev/null.
Phase 1 done: 79 tests passing, analyze clean.
