That image host answers non-browser clients with an HTML placeholder, so the proxy identifies as a browser for that one host and as itself everywhere else. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_NSW_ENABLED=0`. - **Open Calgary traffic cameras.** Keyless. The camera list is the public Socrata dataset `k7p9-kppz` on `data.calgary.ca`; frames are stills on the city's own `trafficcam.calgary.ca` host, and only that host is registered. Most rows publish an `http://` frame URL and the host redirects those to HTTPS, so URLs are upgraded and pinned to that origin before registration. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `quadrant` field and the quadrant suffix on each camera name are Calgary's address grid, not a bearing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. The licence requires the attribution statement above. Disable with `CCTV_CALGARY_ENABLED=0`. - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals. +- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All seven registered regions are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. - **Radio Browser.** `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply. - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 40,000, a configurable application safety ceiling, not a guarantee of staying within TomTom's monthly free allowance; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app). - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line. @@ -79,10 +87,12 @@ How to read this: --- -## Bundled snapshots (committed under `src/data/local_data/`) +## Bundled snapshots Static datasets shipped in the repo for an out-of-the-box experience. **None are MIT** — each keeps its own license (see the carve-out in [LICENSE](LICENSE)).

Other proxies target fixed upstream hosts. - **Radio is not an audio relay.** `/api/radio/stations` contacts only allowlisted Radio Browser HTTPS hosts and paths, rejects redirects, rejects any hostname with a loopback/private/link-local/metadata/non-public A or AAAA result, and pins each TLS connection to a validated address. It returns normalized public HTTPS stream URLs; `/api/radio/click/:uuid` applies the same destination policy and accepts only station IDs from the current bounded catalog. The browser then connects directly to the broadcaster after an explicit playback action, so the broadcaster sees the listener's IP address. GEV never proxies, caches, records, or redistributes audio. - **No verbatim client headers upstream.** The CCTV media route is the one route that relays a request header (`Range`, for video seeking). It is parsed and canonicalized before it is forwarded: one `bytes=` range only, with every accepted form — explicit span, open-ended and suffix — bounded to the same 64 MiB ceiling the relay applies to a declared response body. Multi-range, malformed, inverted and non-`bytes` values are dropped and the request proceeds without a `Range`, as RFC 7233 §3.1 prescribes. Bounding the request bounds what is asked for: a response that declares no length — live streamed media, or a chunked body from an upstream that ignores the `Range` — has no ceiling. An upstream request the browser has stopped waiting for is cancelled rather than left running, whether the viewer leaves before the headers arrive or during the body. +- **Transit fetches registered feeds only.** `/api/transit/vehicles/` resolves the id against `src/data/transitFeeds.js`; the browser never supplies a URL, and a feed that is registered but disabled does not resolve at all. Redirects are followed manually and each hop is validated against the feed's own https origin before it is requested, so an off-origin or downgraded hop is refused rather than contacted. Bodies are capped at 8 MB, the protobuf is decoded server-side under entity-count and string-length ceilings, a differential feed is refused, and snapshots live 15 s in memory with no disk cache. A per-feed admission limiter and a failure cooldown ladder bound what this process can ask of any operator. - **Response-size caps and timeouts** on proxied responses. - **Sanitized errors** — internal error details are not echoed back to clients. - **Coalesced OAuth refresh** and cached successful responses only (OpenSky). diff --git a/docs/CODE-BOUNDARIES.md b/docs/CODE-BOUNDARIES.md index 41b674996..35409e1d4 100644 --- a/docs/CODE-BOUNDARIES.md +++ b/docs/CODE-BOUNDARIES.md @@ -1,16 +1,19 @@ # Formatting and component boundaries -Run `npm run format` to format the files in `scripts/format-scope.json` and +Run `npm run format` to format the files in `scripts/format-scope.json` plus +automatically discovered runtime JavaScript in `scripts/format-runtime.json`, and `npm run format:check` to check that same list without writing.

Source rasters are 48/96 px before padding. +External halos are 1/1.5 px in normal and 3/3 px in sensors, calculated from the +final unpadded display size. Six modes, two sizes and three profiles cap the +raster cache at 36 variants. Normal mode colours are bus `#5EF08A`, tram +`#FFC24A`, subway `#FF4538`, rail `#D9A6FF`, ferry `#5FD6FF`, and unknown +`#D8DDE5`. Selection keeps the mode colour. Sensor bodies use solid rounded envelopes with at least 60% opaque white coverage +of the padded display footprint, without interior panel lines. Sensor input is opaque white with a +fully opaque black halo; black-hot reverses the contrast through the +thermal effect. Creation, mode changes, selection, deselection, map presets and +Cockpit vision use the same sprite styling function. + +Sensor signatures remain in-scene. The thresholds in `qaMetrics.js` require +white-hot, Ironbow and noir centres ≥0.85 luma and halo minima ≤0.25; +black-hot uses centre ≤0.15 and halo maximum ≥0.75. Surveillance uses ≥90% +of its phosphor peak white (0.65992 from RGB 0.16/1/0.22), halo minimum ≤0.25 +with the centre minus sampled background reported without gating. Each preset needs at least +six verified, unobscured sprites; insufficient coverage is UNEXERCISED. +The sampler excludes overlapping footprints, including otherwise ineligible +sprites, and verifies pick ownership across all nine sampled core pixels. +Noir samples also exclude its deliberately vignetted outer field, using shader +settings and screen position rather than observed brightness. Selected-trail +diagnostics report every condition even when selection fails. + +Transit brackets use the normal-composite overlay surface: a 1.25 px mode-colour +stroke over 3.25 px dark backing. Other contact themes retain their existing +behavior. The selected trail uses a 2 px core over 4 px backing, mode-coloured +in normal and white input in sensors. Alpha falls linearly from 0.80 at the head +to 0.45 at two minutes, 0.20 at ten minutes and 0.08 at fifteen minutes. + +**Cards and DETECT.** The card presents route, mode/operator, displayed motion, +display delay and newest-report age, reported speed/stop, vehicle ID, and +available trail duration. Its anchor follows the rendered marker; text is +checked at 4 Hz and published when it changes. DETECT labels retain route, +mode and motion, with the selected label suppressed beside its fuller card. +Candidate membership changes on revisions, coalesced at 4 Hz; paints read +cached contacts and strings. Marker migration explicitly updates cached +position references. Freshness and delay use the shared sample’s anchored clock; +newest bearings are explicitly labelled as reports. Rejected fixes cannot alter +lag reservoirs or the target delay. Returning from a hidden tab explicitly +synchronizes visible playback before its next frame. + +Playback reserves numeric scratch before the first sample, including unknown +heights, and reuses caller-owned sample and segment storage. + +**Scene work.** Stationary and animated billboards use separate, adjacent +collections above CCTV and Bikeshare. Traffic, Bikeshare and Transit share camera +sensitivity claims; the original sensitivity returns after the last release. +Visibility checks combine the camera frustum and ellipsoid occlusion at no more +than 4 Hz; missing map bounds do not admit the globe's far side. Frame work +visits moving visible vehicles, up to 64 pending height changes, and the selected +head. Rotation visits visible membership at 5 Hz, with selected rotation per +frame. The transit render hold exists only for visible positional or orientation +animation. Polls, surface completions and trail fades request individual renders. +Disable clears vehicles, detection references, requests, timers and holds; +destruction also releases collections and registrations. + +**Acceptance harness.** Run against an already running development server: + +```sh +QA_BASE_URL=http://localhost:4305 QA_TAG=keyless node scripts/qa-transit.mjs +``` + +The full run samples completed frames at 1920×1080 CSS pixels, records DPR, and +measures moving fleets of 800 and 3,000 vehicles with 128 fixes each and DETECT +on.

The 3,000-vehicle CPU budget is 4 ms (recorded browser +measurement 3.4 ms); the 800-vehicle budget stays at 1 ms (measured 0.9 ms). +Transit-authored frame allocation is ≤8 KiB/frame at both fleets, attributed +by source stack to `src/layers/transit/**`, `src/data/contactPlayback.js`, +`src/data/contactTrailRenderer.js` and `src/data/transit*.js`.

Heap growth is measured +conservatively as GC-bracketed page growth; allocation sampling includes objects +collected during the interval.

Matrix routes are +scripted fixtures; the separate live-feed/reload checks use actual observations. +The separate Boston live pass uses actual MBTA observations at 120–600 m and +20–45 degree oblique views, with live selection and sensor readback. +Live visual cities are otherwise chosen for local daytime operation. Motion checks use +injected playback independently of live fleet activity. Thermal checks verify +style activation before reading generated controls; DETECT checks set density +and exercise the real OFF/restore button. Cesium render errors fail selection +acceptance. +Required empty or unexercised checks fail acceptance. The passing final line is +`HARNESS: PASS (0 unexercised)`. A `QA_SECTIONS` subset is diagnostic only and +cannot claim full acceptance. + +**Lifecycle and proxy.** Contacts temporarily disables Transit and restores its +prior state on exit; Space Missions refuses enablement while isolating replay +data. Cockpit enters through Contacts and does not independently enable Transit. +The proxy fetches registered URLs only, validates redirect origins, bounds +responses and decoding, caches successful snapshots, and backs off after failed +refreshes.
