A map keeps the datum it was built with, and Leaflet cannot change one
afterwards. The basemap could still turn into Amap's after the fact: a first
settings request that fails leaves the store on defaults for the session and is
healed later, and the raster layer then drew GCJ-02 tiles under a map still
projecting WGS-84, putting every marker, route and cluster a few hundred metres
off the street beneath it until the planner was left and reopened. The datum is
part of the element's identity now, so a flip rebuilds the map. Only the datum:
keying on the whole tile URL would throw the view away on every template edit.
Index POIs were labelled by an exact lookup of a term the index matches as a
substring, so any leaf that is not literally a term missed and took the first
category of the request instead. In a corridor search that is whichever pill
was tapped first, and the panel groups and colours on that field: a trattoria
came back as a petrol station, or a petrol station as tonight's hotel. The
label now comes from the term that actually matched, longest first.
Two outbound reads were missing what the house rule asks for. The brand-logo
fetch had no deadline at all next to a Wikidata hop that allows six seconds, so
a stalled CDN held a request context and a socket for undici's five-minute
default, and its size cap only applied after the bytes were in memory. The
Wikimedia photo proxy beside it had the same shape. And the Amap provider
buffered every answer uncapped and trusted a cast for its arrays, so a `pois`
object rather than a list threw a TypeError that surfaced as a 500 instead of
the OpenStreetMap answer.
With Amap in the keyed slot every reverse lookup went to Amap first,
worldwide. Outside its box that buys a round trip and an empty answer
before Nominatim is asked anyway, which is latency on every right click in
Lisbon. The client side of the same question already filters by the box
(placeNavigation.ts); isOutsideChina is the shared helper both use.
The two fixtures in the file that were cast to any now carry a type: the
key row and the fetch spy whose calls the reverse case reads back.
The rebase kept maps.service.ts as dev has it: the TREK index and
OpenStreetMap answer every search first, and a keyed provider only fills
what they leave empty. Amap now sits in that slot next to Google instead
of behind an extracted Google provider, which is dropped.
places_provider (auto | google | amap | openstreetmap) decides which keyed
provider holds the slot; auto keeps whatever the install already used.
An amap: id opens against the Amap key regardless of the setting, takes
the plain details lookup on expand, never reaches Google's photo call,
and a pasted Amap link resolves through parseAmapUrl. Reverse geocoding
asks Amap at the instance key before Nominatim.
The migration carries users.amap_api_key, which the rebase had left at a
stale array position, and places.amap_poi_id for the next commit.
