The drive from where one day ended to where the next begins was the one stretch of a
connected road trip that offered no other ways. The band above a card's first stop had no
button on the desk, and the phone did not show that drive at all. A via behind a day's last
stop, where the map already files a point dropped on that drive, was deleted when the day
was reordered under Days, and was left on no stop when that last stop was removed or
dragged up the day. Switching the avoided road classes or the day's profile kept the old
road and minutes on it until a reload.
The drive in now opens the same picker as any leg, on the desk band and on a new row at
the head of the phone's chain that names where it leaves. A choice is proven with the
seam's own router and written behind the last stop of the day before, also when a day with
a single stop lies between. The rule for that via lives once in shared (carriedSeam): it
stays with the last stop while that stop stays last, and is read like any other once it is
not, for the planner's drags and removals as for the server's sorts and seated nights. The
cached answer for a seam now records its mode and avoided classes, so changing either asks
for it again.
The picker of other ways asked OSRM with nothing avoided while the rail drives a trip
that avoids a road class through Valhalla, so the list had no current road, called a road
the rail was not on the fastest, and choosing it changed nothing. A choice was stored as
one via where the offer strayed furthest, without asking whether the router then drove
it: a point on a ferry was pulled to the pier and the drive went overland, and a way
weighed away from motorways kept the motorway after its one point. An OSRM answer standing
in for a Valhalla that did not respond was cached as the avoided road, unmarked.
The rail now hands out a router per leg with the leg's own mode, avoided classes and
engine, and its days carry the line of every leg. Offers come from that engine, and the
rail's own leg always heads the list as Current. A choice is pinned and proven against
that router with at most three pins before anything is written; a way it will not follow
is not saved and says why, with a hint when it crosses by ferry, and a leg that changed
meanwhile or a device offline writes nothing. The OSRM stand-in is filed under the plain
key only and flags the day as not avoided.
It named the day's destination with its picture, its stop count, its arrival and the
stage distance, and it stood there for the whole of the road trip tab. The day and
the distance are in the shell's stage header already, and on a map that fills the
screen a permanent card over the bottom edge costs more than the three facts it
added. Tapping it opened the destination's stop sheet; the chain opens the same sheet
from the row that names it.
The slot stays for the one bar that earns it: while other ways of driving a leg are
on offer, the picker's bar stands there. That wrapper is now mounted with the bar
rather than lying empty over the map's own buttons the rest of the time, and the map
floor lifts only while it is up, so on the stage the round controls stand on the dock
like everywhere else.
The desk offers alternative routes from the drive band between two stops;
the phone had nothing. A leg in the phone chain now carries one round
button that asks the router for other ways and switches to the map, where a
bar takes the stage bar's place: the ways as chips with their colour, time,
distance and what sets them apart, and a confirm button. On glass there is
no hover, so a tap on a chip or on a line only previews that road; confirm
writes it. The button shows only where the desk offers it (a routed leg
between chosen stops), for someone who may edit the day, and not offline,
since vias are written online only.
The picker could not have stayed open on a phone at all: the planner closed
it whenever road trip mode was off, and that mode is off on a phone by
design, so the next render shut it. The close now follows where the picker
can be seen (road trip mode on the desk, the road trip tab on a phone), and
useRouteAlternatives returns a memoised object.
The rules both shells need are shared: legReroutable in the row model,
alternativesPhase and alternativeSubline next to the overlays, and the desk
bar and sidebar read them too with no visible change. Both map engines take
an optional fitPadding, so the phone frames the leg between the day chips
and the bar instead of under them.
