The keyless fallback landed on the LOCATION search box only. Two other places
forward-geocode a name and neither had it: the annotation resolver returned
null, so an annotation silently failed to anchor, and the Radio layer THREW,
which surfaced as a failed voice turn rather than as a station it could not
place. src/keylessGeocoder.test.mjs now COUNTS the call sites instead of
checking them file by file, so a second seam added to a file that already has
a fallback fails the suite too.
The annotation path carries the feature's own name out of Photon. Footprint
scoring matches OSM on that canonical name rather than on the user's words, so
incidental locality tokens cannot win: "the monument near the Texas Capitol,
Austin" scored on the raw utterance picks a downtown building that shares only
"Texas", "Capitol" and "Austin".
Photon's country is deliberately NOT re-exported. It comes back in the
feature's own language — "Việt Nam", "日本", "Россия" — and
normalizeRadioCountryInput fails CLOSED on a name it cannot map, so forwarding
it would filter the station list to nothing for exactly the places the lookup
had just resolved. The composed label still names the country. A keyless
lookup must not apply a filter the keyed one never applies.
A not-found is now remembered only when every source consulted returned a
verdict. Photon not replying is a network blip, not "no such place": memoizing
it kept the query answering not-found for the rest of the session on a network
that had since recovered — the same conflation the Overpass disk cache had to
be repaired for. geocodeMissIsDefinitive states the rule once and both entry
points use it, and the adapter's own memo follows it as well.
Reverse geocoding stays out of scope: the street-label reader consumes
Google's ranked address_components, and Photon's /reverse cannot reproduce
that shape.
Photon scores proximity against the name, so a viewport bias could outrank
an exact name match by distance alone. Searching "Hue" from Austin returned
Hutto, Texas; "Ha Long" returned Long Branch. Measured against the live
service over twelve Vietnamese place names, three resolved to the wrong
continent.
Google's `bounds` prefers a result inside the box without changing what
qualifies as a result, and that is the semantics this adapter promised to
reproduce. So a biased answer is now accepted only when a candidate leads
with the name searched for, and the query otherwise re-runs unbiased — one
extra request, on exactly the searches that were going to be wrong.
Matching leads rather than contains, which is what separates "Hue" from
"Nguyen Hue Road", and compares unaccented so "Hue" and "Huế" are one name.
On the unbiased pass the head of a "place, region" query is matched first;
the tail only says where to look.
Nearby searches are unaffected: "Sixth Street" and "Barton Springs" over
Austin still take the biased answer in a single request.
Place search was Google-only: searchAndFlyTo threw without a key, and with a
key whose Geocoding API is not enabled it returned nothing. Both cases leave
the LOCATION box and the fly_to_location voice tool unable to resolve a name,
even though every other layer in the app works keyless.
src/keylessGeocoder.js adapts Photon (komoot, over OpenStreetMap) into the
shape the Google path already produces — lat/lng, label, Google-style types,
{southwest,northeast} bounds — so geocodeNavigationMode, regionFramingPlan and
the region-swath cap keep running on unchanged inputs. The translation lives at
the boundary and nowhere else; Google remains primary and its branch is
unchanged when it answers.
Detection is the empty result, not an exception: an unenabled Geocoding API
answers HTTP 200 with REQUEST_DENIED. Places near-view recovery is now
attempted only when a key exists, since Places is a Google service too.
Three translations are load-bearing, and each was found by querying the live
service rather than by reasoning about OSM tagging:
- Google's `bounds` PREFERS results inside the box; Photon's `bbox` FILTERS to
it. Sent as a bbox, searching "Ho Guom, Ha Noi" while looking at Austin
returns features: []. Sent as Photon's lat/lon proximity bias it finds the
lake, and "Sixth Street" still resolves to Austin's over Austin and to
England's over London.
- Photon's `extent` is [west, north, east, south]. Read as [w,s,e,n] it yields
an inverted but finite box that frames the camera at nothing.
- A specific OSM key=value rule must beat the coarse `type`. Photon tags a lake
`water=lake` with `type: 'other'` — unmapped, that framed Hoan Kiem Lake as a
precise place and put the camera 26 m over the water — and tags a town square
`type: 'locality'`, which framed Times Square as if it were a city.
searchAndFlyTo no longer throws when no key is present. Both callers already
read a null return as not-found (ui.js renders its miss branch, gevActions
reports ok: false), so the removed throw has no consumer.
Verified end to end through the real search box, with a key Google refuses:
one denied Google geocode, one Photon request, camera from Austin
(30.2700, -97.7400) to 21.0288, 105.8524 — Hoan Kiem Lake to within metres —
and "Ha Noi" framed at province scale. npm test 2604/2604; npm run build
clean; npm run test:track 97/3, the same three failures unmodified main
produces on this machine.
