`createVectorTileSource` took `tileJsonUrl` and `allowedOrigin` as independent
options, and `createOpenFreeMapSource` hardcoded both to the default host. A
caller that repointed only `tileJsonUrl` — the obvious single change — kept the
default `allowedOrigin`, so the TileJSON's absolute upstream `tiles[0]` passed
the origin check and every tile was fetched from the default host instead. No
error, no warning, and nothing reached the configured mirror.
`allowedOrigin` now defaults to the origin of `tileJsonUrl`, so repointing one
option is enough, and a mirror that serves the default host's TileJSON verbatim
fails with the existing `Invalid vector tile origin` instead of silently
bypassing itself. The origin check is unchanged: a TileJSON still cannot point
the client at a host the caller did not configure.
All three existing callers pass `allowedOrigin` explicitly
(`openFreeMap.js`, `alpr/source.js`, `traffic/flowSource.js`), and an explicit
value still overrides the derived one, so behaviour is unchanged for every
current call site.
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.
