Adds GlassPanel (BackdropFilter + translucent fill + subtle border, values
lifted directly from the Stitch exports' own bg-surface/90 backdrop-blur-xl
border-outline-variant/30 treatment), FloatingPill (a GlassPanel shaped as
a capsule around an arbitrary number of labeled stat columns with
dividers), and PulsingLocationMarker (expanding-ring-plus-glow-dot,
matching the exports' pulse-ring keyframes exactly, with a static-dot
fallback when reduced motion is requested). Pure presentation -- every
UI-04/05/06/07 screen composes these rather than reimplementing blur/
border styling per screen.
Adds outlineVariant to ripprColors, needed for the panel border and pill
dividers and not previously wired up by UI-08.
Verified with a throwaway preview entry point (deleted after use, no
consuming screen exists yet) plus 8 new widget tests covering blur/
translucency/border structure, contrast in both themes, arbitrary stat
counts, and the pulsing marker's animation lifecycle and reduced-motion
fallback.

Adds MapConnectivityState, a shared tracker of tile-fetch outcomes (cache
miss + network failure) that flips every map into an animated skeleton
after 3 consecutive failures and recovers on a single success -- either an
ordinary fetch succeeding, or (once TileLayer has been fully unmounted in
skeleton mode) a periodic single-tile probe every 15s. Detected at the
fetch level rather than via an OS connectivity API, since a captive portal
or degraded connection can report "online" while every real fetch times
out.
SkeletonMapLayer reuses the Stitch exports' 40px grid-overlay treatment
with a shimmer sweep, replacing TileLayer entirely (never fetching
underneath its own placeholder) while markers/polylines keep rendering
since they come from local data. RideMap and the route planner's
independent FlutterMap both wire this in via a plain skeletonMode bool.
Moved the tile-source constants into a new tiles/tile_config.dart so the
connectivity probe (in the app-layer composition root) doesn't need to
import from ui/ to build its request URL.
Verified end-to-end on a real emulator: cut network, cleared the tile
cache, confirmed the skeleton renders after real fetch failures, then
confirmed automatic recovery within one probe interval once network
returned -- not just via the widget/unit tests that also cover this.

Replaces OSM's tan/cream default raster style with CARTO's "Dark Matter"
basemap (both RideMap and the route planner's independent TileLayer), so
the map itself looks like the dark mockups rather than a light basemap
under a dark overlay. Shares one urlTemplate/subdomains/maxNativeZoom
across both call sites instead of two independently-drifting copies.
Re-points the V3-11 tile cache at a versioned directory (tiles/carto_dark_v1)
since TileKey(z, x, y) carries no provider identity and would otherwise
silently serve stale tan tiles cached under the old scheme. Added a test
proving cache isolation holds across provider directories.
Adds a shared TileAttribution widget crediting both OpenStreetMap (CARTO's
style is still built from OSM data) and CARTO, composed into every map
rather than duplicated per screen -- OSM-only credit stopped being
sufficient once a second tile host entered the mix.

Replaces V3-16's safety-orange identity with the palette actually backing
every fetched Stitch mockup (confirmed by hex-matching against all three
design systems in the Stitch project, not by trusting its declared default).
Ground drops to #0a0a0c with a three-level surface/card stack, primary
becomes Professional Blue (#4090fe), and reference readings move to a new
tertiary orange since blue is no longer free for that role. Re-verified
theme_test.dart's AA contrast assertions against the new values (all pass
with wide margin) and left mounted mode's separate daylight palette alone,
per the ticket's own reasoning.
Also resolves the ticket's named risk: RideMap's speed-gradient hardcoded
hex literal, which would have washed to a single hue now that primary is
blue, now lerps from the theme's own secondary token instead.
Inter is not wired in -- no bundled font asset exists to back the family
name, and setting one without an asset would silently fall back to Roboto.
Documented as a deliberate follow-up rather than a silent gap.

Replaces the push/pop stack rooted at Record with a StatefulShellRoute
(Map/Rides/Plan/Settings), each tab keeping its own navigator so Trip Detail
and the route planner push within their own branch. AppShell/ShellScaffold
host one shared RideMap instance behind every tab -- full opacity and
interactive on Map, dimmed and non-interactive elsewhere -- so the camera
position and live path survive a tab switch instead of being refetched.
Every tab's AppBar/header is removed per the redesign's no-chrome mandate.
Fixes a bug this surfaced: RideMap rendered a structurally different tree
for empty vs. non-empty points, which crashed once the map became a
long-lived shell background instead of a fresh per-screen widget. Unified
the background-map tree shape so it no longer remounts mid-recording.
Verified on Medium_Phone_API_35: all four tabs, live recording surviving
tab switches with the camera preserved, and the real HOME-key lifecycle
tile-drop from V3-04 still firing correctly in the shell context.

Direction written before code, per the ticket's own step 1: safety orange stays primary (authentic to the domain, not decorative), a new instrument-blue tertiary is reserved for reference readings (max/average) vs the live figure, ground warmed fractionally, no new font, no motion -- both argued for directly rather than left undecided.
Instrument blue reuses RideMap's existing slow-speed gradient color rather than inventing a new one, so 'same colour, same meaning' holds between the map and stat rows. contrastRatio() implements WCAG 2.x directly and is asserted (11 tests, both themes, AA normal/large) rather than eyeballed. Applied to StatRow's new 'reference' flag on record screen and trip detail's Max/Avg speed rows -- a token-level + targeted pass, not an exhaustive re-skin, named as a deliberate scope reduction alongside the two criteria (outdoor sunlight verification, golden tests) this environment genuinely cannot satisfy.
Three pure modules: tile_math.dart (tilesForBounds/tilesAlongRoute, hard cap enforced by throwing), tile_cache.dart (FileTileCache with LRU eviction before any write that would exceed the cap), tile_downloader.dart (sequential, rate-limited, cooperatively cancellable, one bad tile doesn't abort the rest). CachedTileProvider wires the cache into flutter_map via a custom ImageProvider and now backs RideMap and RoutePlannerScreen's tile layers, so ordinary viewing write-throughs into the same capped cache.
RoutePlannerScreen gained a route-corridor download action (no rectangle-selection UI -- the ticket names the corridor as strictly better and V3-07 already exists to hang it off of), with a count/size confirmation before any request and a cancellable progress dialog. Fixed a real bug before shipping: a StatefulBuilder-based progress dialog would have started a new overlapping download subscription on every single progress tick; moved to a dedicated StatefulWidget that subscribes once in initState.
Marked partially done: aeroplane-mode verification on a real device is the ticket's own acceptance criterion and needs a phone this environment doesn't have.
shouldInitializeCrashReporting() and scrubExtra() are pure, fully unit-tested decision/scrubbing functions wired into sentry_flutter via beforeSend/beforeBreadcrumb. Config.crashReportingEnabled defaults off; the DSN is a compile-time --dart-define, not a preference. RecordingEngine gained an injected onUnexpectedStop callback, firing once when restoreAfterProcessDeath finds a trip still 'recording' at launch -- the process died without a user stop.
Marked partially done: the ticket's real acceptance criteria (a forced crash landing in a real Sentry project from a release build, inspecting a real payload) need a Sentry account and a release build this environment can't produce.
TripRepository.splitTrip mirrors mergeTrips' transaction shape: splits at a segment boundary, moves the target segment and everything after it to a new trip, recomputes both trips' aggregates from scratch. startedAt/endedAt derive from each trip's actual remaining segments, not copied from the pre-split row. Trip detail gained a split action with a segment-boundary picker and a naming confirmation; a single-segment ride explains why it can't split instead of offering a dead control.
gpxActivityType() maps Activity to Strava/Garmin's <trk><type> vocabulary; Activity.other omits the element rather than writing it empty. The ticket's real acceptance criteria are device/account verification (Strava, Garmin Connect, Google Earth import) which can't happen in this environment -- marked partially done and paired with V3-13's real-ride work in the Outcome section.
Route plans are their own entity (RoutePlan/Waypoint, schema v3), never joined into ride totals or the rides list. RoutePlanRepository recomputes straight-line distance after every waypoint mutation. RoutePlannerScreen supports tap-to-add, tap-to-delete, and hand-rolled drag-to-move via MapCamera's screen/latlng conversions.
Fixed a real bug found by testing: FlutterMap's initialCenter/initialZoom are read once at construction, so building the map before the waypoints stream's first emission froze the camera on null-island. Also documents a genuine ten-minute test hang traced to Stream.first on a Drift watch() query inside testWidgets, which needs a pump-driven Timer that flutter_test's fake zone never advances on its own.
RideNotificationController seam over flutter_local_notifications; RideNotificationCoordinator wires TripRepository.watchActiveTrip() to it and routes Pause/Resume actions back into RecordingEngine. Instantiated eagerly at app root rather than screen-owned, since a pocketed ride has no visible widget tree. Documents an unresolved risk: geolocator's own foreground-service notification cannot be suppressed, so two notifications may be visible until verified on a device.
Wake lock via a WakelockController seam (mirrors LocationSource), gated strictly to actual recording and released on stop/discard/navigate-away/dispose. High-contrast ripprMountedTheme() applied only to the record screen. BigStat gained a scale param for the headline figure rather than a blanket TextTheme.apply, which crashes on Material 3's default theme.
Feeds RideMap from watchPointsForTrip/watchSegmentsForTrip via autoDispose.family providers. RecordingEngine stays map-free (enforced by architecture_test.dart). RideMap gained lifecycle-aware tile teardown and follow-mode, both shared with the trip-detail map.
Built together because V3-02's settings screen needed something real for
V3-03's units to control -- executed in reverse of the ticket numbering, but
both tickets are independently complete.
V3-03: UnitSystem (metric/imperial) lives in domain/models.dart alongside
Activity, defaulting from Platform.localeName on first launch. Storage stays
SI everywhere -- conversion happens only in ui/format.dart, at the last
possible moment, which is now documented as the file's central invariant.
Threaded through all three screens plus the speed histogram's bucket labels,
which relabel for display without changing how speedHistogram itself bins.
Export was deliberately left untouched: gpx()/geoJson() take no UnitSystem
parameter at all, a stronger guarantee than validating one would be.
V3-02: SettingsScreen reachable from the record screen. Map render toggle
(nothing previously exposed mapEnabledProvider to the user, despite it
existing since T15 -- there was nothing to "move off trip detail" as drafted),
unit selector, upload endpoint with http(s) validation, a copyable device id,
and a licences page via Flutter's built-in showLicensePage. Skipped
package_info_plus (static version string instead) and a privacy-policy link
(none published yet) as disproportionate to an S-sized ticket.
Neither ticket needed the ConfigNotifier the implementation notes proposed:
unitSystemProvider reuses the exact StateProvider-seeded-from-Config pattern
mapEnabledProvider already established, since Config mutates its own backing
SharedPreferences in place and re-assigning the same instance would never
notify a watcher anyway.
A real locale-dependent flake was caught, not just anticipated: a test
asserting a fresh Config defaults to metric failed, because this machine's own
locale resolves to a region in the imperial set. Fixed by seeding an explicit
value before asserting, and config_test.dart's locale test was written from
the start to only prove the fallback path doesn't throw, not to assert which
value it returns.
221 tests (211 -> 221): 13 format_test, 9 config_test, 9 settings_screen_test,
1 confirming the record screen's settings button is genuinely wired. Analyze
clean.

Adds Activity (motorcycle/bicycle/scooter/skateboard/running/walking/other) as
a column on Trip, and threads it through as real behaviour rather than a label:
ActivityProfile (domain/activity_profile.dart) carries a noise floor, accuracy
gate, histogram bucket width, and elevation smoothing window/threshold per
activity, consumed by sanitizeSpeedKmh, isUsableFix, computeSummary, Accumulator
and speedHistogram. The motorcycle profile reproduces the exact constants the
app shipped with before this existed, and a test asserts they never drift apart.
This is the port's first real migration: schemaVersion 1 -> 2,
m.addColumn(trips, trips.activity) with a motorcycle default so every existing
row survives unmodified. Proven with a hand-built v1 SQLite file (raw sqlite3,
not drift_dev's schema tooling) that a real database with real rides upgrades
and keeps every trip, segment and point.
No picker in front of Start: a new trip defaults to whichever activity was most
recently used, derived live from the trips table rather than duplicated into a
Config field. Editable afterwards on trip detail, which recomputes aggregates
under the new profile immediately -- a walking pace that reads as noise under a
motorcycle's floor reads as real movement once the activity is corrected, and
there's a test proving exactly that transition.
The widget-test pass for the activity-picker sheet caught a real overflow bug:
seven options overflowed a Column-based bottom sheet the same way the record
screen once did. Fixed with a scrollable ListView + isScrollControlled, same
shape as that earlier fix.
188 tests (171 -> 188): 2 migration, 5 ActivityProfile, 3 profile-threading
proofs in computeSummary, 5 repository, 2 widget. Analyze clean.

Launcher, notification and launch screen on both platforms, all generated from
the native app's design sources rather than redrawn.
Android uses the adaptive icon files verbatim from the native app: foreground,
monochrome and the #101418 background colour. That matters because the adaptive
foreground draws its ring at r=32, the corrected radius that survives the
launcher's circular mask -- the first native version used r=43 and the mask
cropped the ring clean off.
iOS gets the full-bleed r=43 artwork instead, which is right there: iOS applies a
rounded superellipse rather than a circle crop, so the wider ring fits. All 15
sizes rendered from the SVG, and the 1024 verified to have no alpha channel,
which the App Store rejects.
The notification icon is ic_stat_rippr, a white silhouette on transparency.
Android masks status bar icons to a solid shape, so pointing this at the colour
launcher icon would render a featureless white blob.
Launch screens were the generated white, which flashes before a dark app on every
cold start. Both now use the app's own tarmac colour with the route mark centred.
Verified on the Android emulator rather than assumed: the launcher shows the
route mark with its orange accent intact, resource 0x7f07007c resolves to
drawable/ic_stat_rippr, and the notification reads "Rippr is recording" with a
clean silhouette. The run also recorded 23 points into a real trip -- the first
time this port has captured anything on Android.

T22 -- TelemetryUploader on package:http with MockClient standing in for
MockWebServer, tested against a real in-memory Drift database rather than a fake
DAO. Upload runs on its own timer, injected as a callback so the engine has no
opinion about HTTP and tests need no network. Config on shared_preferences with
a hand-rolled UUID v4. Still no UI for the endpoint, exactly as in the native
app. 7 tests.
T24 -- integration_test/app_test.dart, 4 tests passing on the iOS simulator.
These cover what widget tests cannot: Drift opening against real platform
storage, plugin registration, go_router driving a real Navigator, cold start.
T26 -- RELEASE-IOS.md. Usage strings are specific rather than generic, which is
the leading Guideline 5.1.1 rejection cause; privacy-label answers decided; a
pre-submission list covering the bundle-id switch back to com.rippr, the still
default app icon, a release build, and a demo video for review notes.
T25 written up as REAL-RIDE-CHECKLIST.md but outstanding by nature. Two items
decide real things: force-stopping mid-ride on Android confirms the 111 km
crash-gap bug is fixed, and parking 15 minutes mid-recording on iOS decides
whether geolocator is sufficient or the paid engine is needed.
Two prefer_initializing_formals lints suppressed with a reason: Dart forbids a
named parameter beginning with an underscore, so the suggested fix will not
compile.

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.

Theme, go_router shell, record screen, trips list with selection, trip detail
with stats and charts, rename/delete/merge. 15 widget tests -- the first this
project has ever had, closing the gap docs/v3/BACKLOG.md names as v2's largest.
The theme sets bodyColor and displayColor explicitly rather than relying on a
wrapping widget, so the black-on-black regression cannot recur by someone
removing a container, and a widget test now asserts the headline names a colour
distinct from the ground.
Those tests immediately found a real layout bug: with a ride active the record
screen grows to six stat rows and overflows a short screen. Compose clipped this
silently, so it may be latent in the native app; Flutter reports it. Fixed by
making the screen scrollable while still centring when there is room.
Two harness lessons. pumpAndSettle never settles against a repeating timer, so
the elapsed clock now runs only while a ride is active -- better behaviour
anyway, since an idle screen has no clock to advance. And flutter_test asserts
no Timer is pending after disposal, which Drift's stream-query keep-alive cache
trips; tests now tear the tree down and pump past that window.
160 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.
145 tests passing, analyze clean.

All lifecycle transitions inside Drift transactions, each idempotent: start
(adopting an active trip rather than duplicating it), pause, resume, complete,
discard, rename, delete, merge, and the authoritative aggregate recomputation.
Room.withTransaction maps onto Drift's transaction() almost exactly, so this was
the most mechanical port so far. 26 tests, green first run.
Merge keeps its hard-won properties: segments are never joined, so the boundary
between two merged rides stays a segment boundary like a pause, and aggregates
are recomputed rather than summed because distance is not additive across the
gap. The regression test puts the two rides a degree of latitude apart and
asserts the ~111km gap never reaches distanceM.
Dropped a mergeTableUpdates helper before committing -- Drift's update() already
notifies dependent streams, so it was scaffolding that earned nothing.
TripRepositoryTest, MergeTest and SchemaTest were 666 lines of instrumented
tests needing a booted emulator. All three now run as unit tests in ~2 seconds.
Phase 2 done: 121 tests passing, analyze clean.

Three tables with CASCADE foreign keys, indices, WAL, and a real MigrationStrategy
from schema version 1. No destructive fallback, ever.
Two things needed deliberate handling. SQLite defaults foreign_keys to OFF and
Drift, unlike Room, does not enable it -- without the pragma every CASCADE is
decorative, so there is now a test that reads the pragma back. And Drift both
snake_cases columns and names row classes after tables; build.yaml sets
case_from_dart_to_sql: preserve so the schema stays column-for-column identical
to Room's, and @DataClassName keeps row types from colliding with the domain
models.
SchemaTest was instrumented and needed a device; the Drift version is a plain
unit test that runs in under a second with no emulator. 16 tests.

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.

T03 — telemetry.dart, format.dart, live_telemetry.dart, plus pure domain models
(Trip/Segment/TrackPoint/RideStats) with no persistence dependency, so Drift can
map to them in T08 rather than the domain depending on the database.
T04 — ride_statistics.dart including ElevationAccumulator, ported structurally
faithfully: moving average, reversal hysteresis, gainIncludingPending, and the
finish() reconciliation against lastRaw.
T07 (early, because T04 forced it) — tool/parity/ drives identical fixtures
through the real Kotlin files and the Dart port, then diffs. Result: every value
byte-identical, including noisy_gain=38.959594555022136 to the last digit. The
sole difference is run_avg_speed, where Kotlin's 32-bit Float widens to double
with artefacts Dart's binary64 does not reproduce. Documented, not papered over.
That harness settled a real question. The ported elevation test failed at 50.9m
against Kotlin's 35m bound, which looked like a porting bug. It was not: Kotlin's
and Dart's Random(42) are different streams. On a shared LCG fixture both produce
39.0m -- which would also fail Kotlin's own bound. The native guard passes on seed
luck rather than on a property of the algorithm. The Dart test now uses the shared
LCG, asserts bit-equality with Kotlin, and sets its bound from measured behaviour
(25 seeds spanned 24.7-46.7m).
52 tests passing.

T00 — toolchain green on both platforms. flutter doctor reports no issues.
Pinned Flutter to Temurin 21 (AGP rejects the default JDK 25, same constraint
as the native build) and installed Android cmdline-tools with an explicit
--sdk_root, the trap already documented in the native DEVELOPMENT.md.
No caches were deleted: the 16 GiB disk reading that drove the cleanup plan
re-measured at 36 GiB before anything was removed.
T01 — flutter create for android+ios. applicationId is com.rippr.port, not
com.rippr, so the native app stays installable alongside it during the port;
T27 switches it at cutover.
T02 — geo/geo.dart ported from com.rippr.geo.Geo with all 23 tests, tolerances
and comments carried over unchanged. Kotlin's object namespace became top-level
functions; LatLon stays our own type so the pure layer never depends on
flutter_map.
