In the keyless setup a single transient failure while loading the default
map layers locked in the degraded fallback until reload.
_getImageryProvider cached the construction-fallback resolution (OSM) under
the Esri stack id, so every later "Esri Satellite" selection showed OSM.
createKeylessTerrain turns any Re:Earth failure into a flat
EllipsoidTerrainProvider; the controller cached it and set _terrainMode to
'keyless', so a boot-time network blip left the globe flat.
Fallbacks are still cached and shown at once, and no switch waits on a
retry. One controller timer now retries the real provider behind whichever
fallback is on screen (Esri's OSM stand-in, or flat terrain on a shown
globe), starting at 30 seconds and doubling to a 10-minute cap while it
keeps failing. A failed retry leaves the cached fallback and the installed
terrain untouched. A success replaces the cache entry and applies it live:
terrain is installed in place with a render request (or, behind a 3D
tileset, picked up by the next globe activation), and Esri is reselected
automatically, after any in-flight switch settles. A switch that read the
flat fallback re-reads the terrain cache before installing, and destroy()
cancels the timer and releases a provider built after it.
Traffic roads come from OpenFreeMap vector tiles, or TomTom flow tiles with a
key (Hybrid by default). Military areas use OpenFreeMap polygons with a bundled
worldwide name index; wide views show named points. ALPR reads an hourly
OpenStreetMap extract. Cockpit place context and country, state and US county
outlines use bundled Natural Earth and US Census data. Overpass is used only
when an operator configures their own endpoint.
Also: camera arrivals no longer land below ground, keyless terrain retries on
429, bounded relation geometry for configured Overpass, one shared
OpenStreetMap credit, and separate tile and API transports for embedders.
