## NYC DOT TMC CCTV source pack
The CCTV catalog can add New York City traffic cameras from the NYC DOT
Traffic Management Center. NYC DOT requires developers to sign a data-sharing
agreement for the camera feed, so this is the one opt-in pack: it loads only
when `CCTV_NYC_ENABLED=1`, and with the flag unset the server makes no NYC
request. NYC DOT's requested disclaimer is in the Data attribution popover.
When enabled, the server reads the keyless
camera list at `https://webcams.nyctmc.org/api/cameras` and keeps cameras the
feed marks online. Frame URLs are built from each camera UUID under
`https://webcams.nyctmc.org/api/cameras/<uuid>/image`; they are never taken
from the payload. There is no heading in the feed, so gizmos use the shared
id-hash fallback at low confidence.
Once enabled, the 250 cameras nearest the five borough cores load.
`CCTV_NYC_MAX_SOURCES` sets the pack cap (8–400). The catalog-wide ceiling stays at 4,000 and is shared
round-robin, so adding this pack does not silently drop another region.

## GBFS upstream bounds
Station information is normalized in `src/sources/gbfsStations.js` for both the
globe layer and `get_bike_share`. Names accept legacy strings or GBFS v3 Localized
String arrays regardless of the reported feed version. Nonempty English text
(including regional `en-*` tags, case-insensitive) takes precedence, then the first
usable translation. An unusable `name` falls back to `short_name` with the same
rules; if neither supplies text, the station remains available with an empty name
(the globe uses its station-ID label and the tool returns `null`). Malformed
translation entries do not interrupt loading of the other stations. This covers
station names, not complete GBFS v3 support.
`scripts/qa-gbfs-names.mjs` checks synthetic localized names through the real layer,
station selection, keyboard dismissal, mobile cards and bike-share tool against
either a dev or preview server (`--url` selects the target).
The station reader addresses the proxy as `/api/gbfs/<encoded feed URL>`; the
feed address is read from the path, and a query-string form is refused with a 400. GBFS refuses upstream redirects and enforces its 5 MiB response cap while
streaming. The 12-second deadline includes reading the body, and rejected or

Google Street View (`providers/google/`) runs on the Maps JavaScript API with
the browser `GOOGLE_MAPS_API_KEY`, which needs that API enabled; it is loaded
on first use (`mapsLoader.js`, CSP `script-src https://maps.googleapis.com`).
Its chip starts off (`defaultOn: false`; a link without its switch keeps it off) because every
panorama load is billed to the key. Google's terms forbid Street View beside
non-Google maps, so the provider declares `requiresMapStack: 'photoreal'`:
off Google 3D it does not appear at all (no chip, legend swatch, globe
credit, layer source or button, and Google's script is not loaded), lookups
and opens skip it, and leaving Google 3D closes its panorama; the share
option keeps the user's choice for when Google 3D returns. Google offers no coverage layer
for other maps, so it draws none: with it on, a click on the map itself
(`scenePick.isSurfacePick`: nothing picked or Google 3D tile content, so a
Mapillary line under the pointer wins; no tool holding the pointer; camera
below 3 km) opens its nearest Google-collected outdoor panorama within 50 m
and leaves the camera where it is (`groundClick.js`). Higher up the hint
says to zoom in. **OPEN STREET VIEW** beside that hint (`#sl-nearest-btn`)
does the same at the view centre, so Street View needs no pointer; it is
disabled until the camera is at street zoom (and aimed at the sky, it opens
nothing and says to aim at a street). One provider is lit at a time:
`setProviderEnabled(id, true)` darkens the others, a chip click sends every
switch in one update so the share link records the swap, and params that
light several keep the one already on, else the first in chip order
(`litByParams`; reapplying them never flips). Mapillary, free, is lit by
default. The chip reads GOOGLE STREET VIEW, and an open panorama's globe
marker is a Google-blue view cone (`marker: {kind: 'view-cone'}`) in place
of GEV's amber pin. Its
panoramas are all 360° and it draws no coverage, so it declares `filters: []`
(a provider's `filters` default to both `pano` and `since`): lookups ignore
the IMAGERY and SINCE filters, the panel hides each filter row no lit provider
honours (`filterControls`), and the legend lists only providers that draw
lines, with "Selected" only beside one of them. The viewer is Google's `StreetViewPanorama` in its own
element in the viewer host, without Google's fullscreen, close and address
controls (the address goes in the caption); a pose goes out at once and
again when the panorama's month, photographer and address arrive (one
successful lookup per panorama per session, seeded by the nearest lookup;
a details lookup that fails or takes over ten seconds waits five seconds
before a view event can retry, and an unmount drops lookups in flight). A key
Google refuses (`gm_authFailure`: the API not enabled, a referrer it does
not allow, billing off) reads KEY REJECTED and fails a pending open at
once; a lookup or open Google never answers fails after 10 or 20 s. In CI
(no Google key, no Google 3D) the gate checks that nothing of Street View
shows off Google 3D, even switched on by a share link; the click and button
step skips as `no Google key`.
