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.
