- The chip reads GOOGLE STREET VIEW (and its caption link likewise).
- Providers declare the imagery filters they honour (`filters`, default
pano + since). Street View declares none: every panorama is 360° and it
draws no coverage to thin, so its lookups ignore the filters and the
panel hides IMAGERY and SINCE while it is the only lit provider.
- The legend lists only providers that draw coverage lines, with
Selected only beside one: Street View alone shows no legend.
- Providers may pick their on-globe marker (`marker`); Street View's is a
Google-blue field-of-view cone from a white-ringed dot, in place of
GEV's amber pin, and switches back for a Mapillary photo.

- An open after a failed one is no longer failed by the old panorama's
status: only status_changed can reject; position_changed only resolves.
- A nearest lookup aborted, timed out or refused while Google's script
loads no longer sends its getPanorama request once the script arrives.
- A panorama-details lookup that never answers times out after 10 s,
cools down and retries; an unmount releases lookups in flight, and
their late answers are dropped.
- Every Maps loader on a page shares one script load and ready callback,
and either can retry a failed script.
- OPEN STREET VIEW aimed at the sky opens nothing and says to aim at a
street, instead of looking up the camera footprint.

Google's Maps Platform terms forbid Street View imagery beside non-Google
maps, so the provider declares requiresMapStack: 'photoreal': off Google
3D its chip is dashed with the reason, lookups and opens skip it, and
leaving Google 3D closes its panorama.
- Ground clicks: only a click on the map itself (scenePick.isSurfacePick:
nothing picked or Google 3D tile content) at street zoom opens Street
View, and the camera stays put; higher up the hint says to zoom in.
scenePick.pickGroundPosition replaces the copy in Directions.
- Viewer: poses go out at once and again when the date and address
arrive, so an open never hangs on that lookup; one lookup per panorama,
seeded by the nearest lookup; a close settles a pending open; failed
lookups are asked again; poses follow position changes, not pano_changed.
- Loader: the gm_authFailure handler is installed once, so a retried load
reports a refusal once.
- Viewer host: a prewarm that lands after another provider took the host
is released; FIT/FILL availability is set on every open.
- Provider: a refusal while switched off reports no error over another
photo; SINCE compares against the end of Google's month; messages name
the referrer and network causes; FLAT says Street View is 360° only.
- The layer row names the key of the providers that are on; the MCP panel
CSP admits Street View's tiles, control images and photos.
- Tests for each, against fakes that now follow Google's event order; the
browser gate restores its state, waits instead of sleeping, aims its
panel clicks and corner drags, and asserts the camera stays put.

Google Street View registers beside Mapillary as provider `google`. It runs
on the Maps JavaScript API with the browser GOOGLE_MAPS_API_KEY, loaded on
first use (mapsLoader.js), and uses Google's own StreetViewPanorama as its
viewer adapter, emitting provider-neutral poses (address and month in the
caption, a link to Google Maps, steps along Google's arrows, FOLLOW on
Google 3D). Its chip starts off because every panorama is billed to the
key; the share option is `g`.
Google offers no coverage layer for other maps, so the provider draws
none: with it on, a click on bare ground at street zoom opens its nearest
Google-collected outdoor panorama (groundClick.js). A key Google refuses
reads KEY REJECTED and fails a pending open at once; a lookup Google never
answers fails after 10 s.
Core: providers may declare `groundClick` and `defaultOn`; poses may carry
`capturedAtPrecision` and `title`; the coverage line keeps every
provider's hint; opening one provider's image releases another's
prewarmed viewer; FIT/FILL hides for viewers without render modes. CSP
script-src admits https://maps.googleapis.com. The browser gate gains two
Street View steps (the keyed one skips as 'no Google key' in CI).
