Captured from maglev @ 91b568ae (branch gtfs-flex) running locally against testdata/alexandria-flex.zip and testdata/charlevoix-flex.zip. Covers /api/ondemand/service, /api/ondemand/services-for-location (point and viewport), /api/ondemand/services-for-agency, and the onDemandServiceIds pointers on /api/where/stop and /api/where/route. Also copies testdata/flex-booking-vectors.json verbatim.
Implements the spec §6 booking deadline algorithm and runs all 21 shared booking vectors against it, comparing state, both instants (including their agency-local offset) and nextBookableServiceDate. countBack returns null when a prior-notice count cannot complete (it reaches the calendar's start date, the calendar has no active days, or the walk exceeds 400 days); evaluate maps a failure on either the last-day or start-day count to UNKNOWN, matching maglev's reference.
A zone tap unfocused the map a level and then opened the service page unconditionally, so over directions it could stage the leave-directions confirmation or peel a leg and still navigate away. Stop and bike taps are refused there (#2097); a zone tap now answers as a plain background tap and never navigates. HomeViewModel owns the decision, asked before the tap unfocuses, so it is JVM-tested with the rest of the focus rules.
The summary took the earliest cutoff over every rule active on the travel date, including rules already closed for it. With a prior-day rule and a same-day rule both running today, the page read "Book by yesterday 17:00 for a ride on today". Only open and not-yet-open rules now supply the deadline: the earliest of those is the safest thing to tell a rider, a closed rule's deadline has passed, and an unknown one adds no bound the client can state.
goToPhoneDialer started ACTION_DIAL unguarded, so on a device with no dialer (many tablets) the on-demand page's Call button and the customer-service phone action threw ActivityNotFoundException. It now toasts instead, as goToUrl does. It also takes the number itself and builds the URI with Uri.fromParts: feed phone text can carry '#' or an extension, which "tel:$phone" would parse as a fragment.
load() launched a fresh fetch without cancelling the one in flight, so a retry during a slow load could be overwritten when the stale answer finally arrived, putting an error back over loaded content.
The three on-demand strings shown in place of content had no context for translators, unlike their neighbours.
The zone-tap predicate was inserted between onBikeStationFocused and its doc comment, leaving the function undocumented and the comment floating above unrelated code.
A stop's onDemandServiceIds name the GTFS-Flex services that serve it, but the arrivals screen had no way to show them. Resolve each pointer through OnDemandDataSource into a small card item (name, kind, pickup booking phone) and carry the list through ArrivalsData into the content state. Services are static data, so items are cached per repository and a 60-second poll never refetches them. A service that fails to load, or a server without the on-demand namespace, just leaves that item off: the arrivals are the screen's job, and the pointer is retried on the next load.
Riders at a stop served by dial-a-ride had no sign of it on the arrivals list. Render the loaded services as a card above the route rows, one tappable row per service showing its booking phone when the feed publishes one, and open the service page through the existing on-demand route (standalone board) or HomeCallbacks (home sheet). The card is a new optional head item, so the promoted-row scroll must count it. Pull that count into firstRouteIndex, a pure function with a test, so the index can't drift from the list's item order again.
The arrivals wait on these fetches before the list can render, and a stop can name several services. Fetching them one after another made the first load of such a stop pay one round trip per service. Fetch the uncached pointers together instead; the card still lists them in the stop's pointer order.
The stale fallback runs because the arrivals fetch just failed, most likely because the network is down. Fetching an uncached on-demand pointer there held the stale arrivals back until that fetch failed or timed out as well. On the stale path, show only the services already cached from an earlier load and fetch nothing.
A clickable modifier on the row's Surface gave it no button role and no minimum touch target for TalkBack and Switch Access. Use the clickable Surface overload, which provides both. Also check firstRouteIndex over all sixteen head-item combinations rather than three samples, and wrap its parameter list for reading.
Keeps the shared booking-deadline vectors byte-identical to maglev's testdata/flex-booking-vectors.json. The new vector pins that the next-bookable search skips dates that evaluate unknown instead of stopping at the first one.
The map already reads preference_key_show_ondemand_zones to decide whether to draw on-demand (GTFS-Flex) service areas, but nothing let the rider change it. Expose it as a switch on the settings screen, following the same snapshot/UI-state/view-model wiring as the existing rental-button toggle.
Locale.getDefault() reads the JVM default once and does not recompose when the user changes the system language, so the formatted day/time/deadline text on the service page could go stale until the screen restarts. LocalLocale.current is a CompositionLocal that Compose UI already updates on locale changes; read its platformLocale to keep java.time formatting unchanged elsewhere. Fixes the NonObservableLocale lint error that lintObaGoogleDebug was flagging on this branch.
A tap inside an on-demand zone unfocused the map a level and then also opened the service page, so a rider tapping a zone to dismiss a focused stop was carried off to a page they did not ask for. The zone tap now opens the page only when the map had nothing to peel: no focus and no directions. Otherwise it is purely a background tap.
The zone layer took its deployment from the region's base URL alone, so with a custom OBA API URL and no region it read "no deployment" and never drew zones, even though ObaEndpointResolver routes every request to that URL. With both set, a 404 was recorded against the region's server rather than the one that answered. Extract the resolver's choice (a non-empty custom URL ahead of the region's base URL) as obaEndpoint and derive the layer's deployment from the same inputs, so the layer, OnDemandSupport and the data source agree. Only demo mode now reads as "no deployment".
The travel date is by construction one on which some rule is open for booking, but the summary took the earliest cutoff over open and not-yet-open rules alike. A not-yet-open rule with an earlier cutoff won, so the page said "Booking opens ..." while another rule was bookable right now. Take the earliest cutoff over the rules that evaluate open on the travel date. An open rule with no booking rule still counts, with no deadline, and supplies "no notice required" only when it is alone.
When the agency timezone was missing or an id java.time does not know, the page fell back to the device zone and computed a booking deadline in it. For a rider in another zone that deadline could be hours late, the one error they cannot recover from. Leave the zone null in that case and compute no deadline: the booking line reads "no deadline published" and the contact details remain. The When rows need no zone and still render. The travel-date search and the open-rule cutoff move into their own functions so the null zone is handled in one place.
presentService searches each rule's calendars day by day for the next bookable date, up to the latest calendar end, which is CPU work the main thread should not do. Hop it onto Dispatchers.Default. The dispatcher is injected under a new DefaultDispatcher qualifier, so the view model test hands in a test dispatcher and stays deterministic.
The deadline line was computed once, when the service loaded. A rider who went to the dialer or browser and came back after the cutoff saw a deadline that had already passed. Keep the loaded service and re-present it against a fresh clock on ON_RESUME, without fetching it again. The clock now comes from the injected TimeProvider so the test can move it past the cutoff.
A list response adapted all-or-nothing: one service with a bad time string, date or bbox threw, and the whole viewport's zones (or an agency's services) disappeared with it. Drop only the service that fails to adapt and keep the rest. The single-service entry stays strict; there the malformed service is the whole answer and the page reports the failure.
The arrivals card shows a service's name, kind and phone number and draws no zone, yet it fetched each service with simplified geometry, about 15 KB per zone that was parsed and thrown away. Give OnDemandDataSource.service a geometryDetail parameter, defaulting to simplified for the service page, and pass none from the arrivals repository.
The architecture doc said the app probes services-for-location once per launch. It queries that endpoint for every settled viewport; what is kept for the rest of the process is only an HTTP 404 answer.
Import order and one wrapped expression spotless normalises; no behaviour change.
When no rule could be booked for any date, as with a seasonal service whose booking window has not opened, the page said the agency had published no deadline, though the feed says exactly when booking opens. The iOS presenter states it. When nothing is bookable, evaluate each rule on its next active service day (a new nextActiveServiceDate, bounded by the latest calendar end and a 400-day lookahead) and state the not-yet-open one whose booking opens earliest. If none is not-yet-open the line is unchanged. A rule bookable now still supplies the deadline from open rules only.
Seen on device with Charlevoix's CC_CC1: the "When" section repeated the same "Mon-Fri 5:00 AM - 12:50 AM" row once per availability rule that shared those days and hours, instead of once. Dedupe whenRows by their displayed (days, start, end) triple, keeping first-occurrence order, matching the iOS presenter's behavior.
OnDemandSupport was a line-for-line copy of NearbyArrivalsSupport: the same synchronized set, the same one-way 404 latch keyed by endpoint URL. Both now extend AbsentEndpointTracker, keeping their own names, DI bindings and the doc comments that explain why each endpoint has to be discovered. This is a cleanup, not a behaviour change.
nextBookableServiceDate and nextActiveServiceDate each resolved the
rule's calendars and built the same date sequence, differing only in the
terminal step. They now share activeServiceDates.
This is a cleanup with one deliberate behaviour change: the bookable
walk is now capped at 400 days like the active walk, as spec §6.4 states
("bounded at 400 days") and iOS already does. Before, it ran to the
latest calendar end date however far away that was. No test asserted
the unbounded walk; all 22 shared booking vectors still pass.
present() wrapped timeProvider.now() in WallTime only to unwrap it again in the same expression. The comment above the function already marks this as the device wall-clock boundary, so the wrapper added nothing. This is a cleanup, not a behaviour change.
OnDemandServiceItem.kind was filled in toItem() and carried through the arrivals state, but the card never reads it; the service page gets its kind from the full OnDemandService. This is a cleanup, not a behaviour change.
Zones sat in the static clear-and-redraw bucket, so every unrelated snapshot change (a stop refresh on pan, a rental toggle, a badge update) destroyed and recreated every zone polygon and its vertex data. Both flavours now collect the zones through onDemandZoneRenderFlow and reconcile them in place with a shared ZonePolygonReconciler, mirroring the route-polyline path: equal zones keep their native polygon, gone ones are removed, new ones created. Zones are matched by value because a MultiPolygon area is several zones under one service id. Polygon click (Google) and zoneAt (MapLibre) work as before. The rendering boundary is the intended change. On MapLibre it also fixes the stacking: classic shape annotations draw in add order with no z-index, and zones re-added on every static redraw used to land above the route lines. When a zone is now added, the route lines are re-added on top (RoutePolylineReconciler.redraw), so zones sit beneath them.
OnDemandItemsTest calls runCurrent() without opting in to ExperimentalCoroutinesApi. CI compiles the tests with warnings as errors, so the opt-in warning failed the unit-test compile. Add the class-level @OptIn the other coroutine tests use. No behaviour change.
When nothing is bookable yet, the service page picked each rule's next service day and kept it only if booking had not opened for it. With a window that shuts the evening before the ride, that day is already closed while the day after is still to open, so the page fell back to "no booking deadline published" although one was knowable. Walk the rule's service days for the first whose booking is not yet open instead. The evaluator's bookable-date lookahead becomes a lookahead for any state so both callers share one walk and one cap.
A transient failure keeps the zones on screen so a pan never blanks the layer. After a region switch or a custom API URL change that kept the previous deployment's zones drawn over a region they do not belong to whenever the first request to the new server failed, since the cache was only bypassed on a deployment change, never dropped. Drop the cache and clear the map when the deployment differs from the one the cached zones came from, before the new fetch is made.
A ring position or nearestPointOnBoundary with fewer than two coordinates was read by index, so it failed with an IndexOutOfBoundsException. The list adapter drops a single service only on IllegalArgumentException or DateTimeException, so one bad position failed the whole viewport response and blanked every zone in it, contrary to the per-service drop the adapter promises. Check the position length up front and fail as malformed input, the failure the adapter already handles, so only that service is dropped.
The service page only rendered a booking rule's infoUrl/bookingUrl as "More information," so a zero-rule service or one whose pickup rules carry no info link never got the link, even when the service itself had one. iOS already falls back to the service-level URL when no booking rule supplies an info URL; match that so the button appears whenever either source has one, without inventing a deadline line for a service that has no rules to compute one from.

Do not delay arrivals while service details load.
If a stop has an on-demand pointer and its service lookup is slow, toData waits for that lookup before the repository returns otherwise successful arrivals. The rider cannot see those arrivals until the slowest lookup completes. Publish the arrivals first, then load the card items independently and update the card when they arrive.
