A hike can ask the router for more than its difficulty limit: avoid steps,
avoid ferries, prefer footpaths, shorter over faster. They sit under the
limit in the planner's details as switches, each with what it really does,
and the info dot says they weigh the way and give way where there is no
other, and that none grades a path. Switching one plans the route again as
one step of the history, and the choice is kept in the draft.
Only preferences the public Valhalla was seen to honour are offered, with
the measured cases beside hikingCostingOptions: step_penalty took Würzburg
to the Festung from four flights to one, use_ferry 0 sent Kiel round the
Förde and Hamburg through the Elbe tunnel, walkway_factor moved Garmisch to
the Partnachklamm onto the paths, shortest cut the way to the Eckbauer.
use_hills and use_tracks showed no effect on foot and are left out, as are
marked, paved and rough ways, for which the router has no option.
tours.hiking_preferences (migration 045000) holds them as JSON, NULL for
none, so no tour saved before routes differently. Only a hike keeps them;
a paddle tour naming one is refused. A copy carries them, and list_tours
and get_tour_plan read them.
The trip copy's waypoint links now follow the copied places inside
TourWaypointsRepository.insertForPlace.
