The routeData Y.Map's ~15 string keys (geojson, coordinates,
segmentBoundaries, road metadata, profile, colorMode, baseLayer,
overlays, poiCategories) were read and written raw at ~30 call sites,
each with its own JSON parsing and casts; parseJsonArray existed twice
and waypoint extraction four times. GPX assembly was duplicated between
SaveToJournalButton and ExportButton, so the saved plan and the
exported file could silently diverge.
- new lib/route-data.ts owns the routeData (+ noGoAreas) schema:
typed read/write, JSON encoding internal, ColorMode moves here
(re-exported from ColoredRoute for existing importers)
- new lib/gpx-export.ts owns GPX assembly: buildRouteGpx /
buildPlanGpx / buildDayGpxFiles / hasDayBreaks; multi-day splitting
becomes a pure, tested function
- waypoint-ymap.ts gains extractWaypoints / extractWaypointData; the
four hand-rolled copies (use-routing, use-waypoint-manager,
WaypointSidebar, use-days) now share it, and WaypointSidebar's
moveWaypoint reuses the round-trip helpers instead of re-listing
every waypoint field
- all hooks/components consume the seam; no raw routeData key strings
remain outside route-data.ts
