-- **🌆 Add a CCTV source pack.** Austin is the reference camera source. Follow the [CCTV integration workflow](docs/CCTV_INTEGRATION.md) for source review, provider registration, proxy security, tests, and attribution. The proxy only fetches server-registered URLs — never client-supplied ones; see [SECURITY.md](SECURITY.md).
+- **🌆 Add a CCTV source pack.** Austin is the reference camera source. Adding another city means a clean public camera catalog with coordinates, attribution, and server-registered frame URLs (the proxy only fetches registered URLs — never client-supplied ones, see [SECURITY.md](SECURITY.md)). City packs are the best first lane.
 - **🛰️ Add or improve a data layer.** Layer factories live in `src/layers/<family>/`, with source, record, controller and renderer owners implementing the layer interface (`init/enable/disable/update/destroy/getStats`, optional `getDetectableObjects`/`getStats`). Use an existing layer as a template, and see [Adding a new layer](#adding-a-new-layer) for what the PR needs.
 - **🎙️ Extend voice control.** Voice arguments are defined in `src/voice/actionSchemas.js`, with server-side descriptions in `server/providers/openai/tools.js` and client-side execution in `src/voice/gevActions.js`. Keep the tool surface tight and the responses honest (confirm only what actually happened).
 - **🎨 Add a visual style.** Styles are GLSL post-process shaders in `src/styles/`.

 - **Via Lietuva / Eismoinfo (Lithuania).** Public road-camera catalogs and periodically updated still images from [Eismoinfo](https://eismoinfo.lt/), credited to Via Lietuva / eismoinfo.lt in the app. **Off by default.** The camera endpoints are the eismoinfo.lt website backend and are not among the services listed in Via Lietuva's [open-data statement](https://eismoinfo.lt/eismoinfo-backend/content?id=44), whose conditions are attribution and reuse on the same terms. Until the statement is confirmed to cover the camera photos, the pack loads only when an operator sets `CCTV_LITHUANIA_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to Eismoinfo. `eismoinfo-backend/camera-info-table` is joined by ID to `layer-static-features/VKR`. Without `lks=true`, the latter returns WGS84 `[latitude, longitude]`; the table's `x/y` instead use LKS-94 metres. Only the official HTTPS `/eismoinfo-backend/image-provider/camera/last?id=…` image endpoint is registered. Catalogs use the shared 15-minute cache; frames are fetched on demand and never bundled or archived. These are periodic snapshots, not continuous video. Camera headings are low-confidence estimates. No API key is required. `CCTV_LITHUANIA_MAX_SOURCES` defaults to 400.
-- **Freeway Bureau and Highway Bureau, MOTC (Taiwan).** National freeway cameras use the Freeway Bureau’s keyless [MOTC 2.0 CCTV table](https://tisvcloud.freeway.gov.tw/history/motc20/CCTV.xml), refreshed daily and fetched at runtime (never bundled). Freeway Bureau data follows the [Open Government Data License, Taiwan v1.0](https://data.gov.tw/license); the app credits the Bureau, names the dataset and links the licence. If that catalog is unreachable and no last-good source list exists, the app falls back to the Highway Bureau’s free [provincial-road CCTV XML feed](https://thbapp.thb.gov.tw/opendata/), with attribution as requested by the Bureau. Its MJPEG streams are accepted only from cctv-ss01 through cctv-ss08.thb.gov.tw over HTTPS; the frame proxy extracts one bounded JPEG per request. This fallback covers provincial roads, not national freeways. Neither feed requires an API key. CCTV_TAIWAN_ENABLED=0 disables both; CCTV_TAIWAN_MAX_SOURCES defaults to 600 (bounded to 1–2000).
-- **Québec CCTV (MTQ / Québec 511, Montréal and scenic links).** `public/quebec-cameras.json` contains 680 MTQ positions from the official georeferenced WFS (CC BY 4.0), 426 Montréal camera locations derived from OSM (ODbL 1.0), and 14 scenic records with per-row provenance and accuracy. The MTQ video is **opt-in** (`CCTV_QUEBEC_VIDEO_ENABLED=1`): the CC BY 4.0 licence covers the camera locations only, and Québec 511's terms for embedding its clips on another site are unconfirmed, so by default MTQ cameras link to the Québec 511 viewer page instead. With the flag set, the 680 MTQ cameras play the operator's five-second MP4 clip directly in the viewer's browser from `www.quebec511.info/Carte/Fenetres/camera.ashx?id=<id>&format=mp4`, only after the viewer presses Play, so Québec 511 sees the viewer's IP address; Québec 511 refreshes those clips every few minutes. A second browser request supplies an approximate map still. The app does not proxy, store, or read video pixels, and no camera images are bundled. The selected-camera credit names both sources: locations MTQ under CC BY 4.0, video Québec 511. Montréal and scenic entries have provider-page links rather than direct frame URLs; their source-page terms apply. The video remains hosted by Québec 511 under its service terms. No API key is required; `CCTV_QUEBEC_ENABLED=0` disables the pack. Confirm Québec 511's terms of use before setting `CCTV_QUEBEC_VIDEO_ENABLED=1` on a public deployment.
+- **Freeway Bureau, MOTC (Taiwan).** National freeway cameras from the Freeway Bureau's keyless [CCTV static table](https://tisvcloud.freeway.gov.tw/history/motc20/CCTV.xml) in the MOTC 2.0 standard, refreshed daily and fetched at runtime (never bundled). Freeway Bureau traffic data is published under the [Open Government Data License, Taiwan (Version 1.0)](https://data.gov.tw/license), which permits reuse, including commercial reuse, with attribution; the app credits the Freeway Bureau, MOTC, names the dataset and links the licence, as its attribution exhibit asks. The table publishes each camera's MJPEG stream on one of four official camera servers (`cctvn`, `cctvn5`, `cctvc`, `cctvs` under `freeway.gov.tw`). The frame proxy relays single images, so each published stream URL is mapped to the same server's single-JPEG path for the same camera number (`/abs2mjpg/bmjpg` → `/abs2mjpg/jpg`, `/live-view/mjpg/video.cgi` → `/live-view/jpg/image.cgi`); only those exact HTTPS pairs are registered, and the still path is not itself listed in the table. These are on-demand snapshots, not continuous video. Camera headings are low-confidence estimates. No API key is required. The table host does not answer from some networks outside Taiwan (the camera servers do); there the pack is empty, logs one warning and retries hourly. On by default; `CCTV_TAIWAN_ENABLED=0` skips the pack, and `CCTV_TAIWAN_MAX_SOURCES` defaults to 600 (bounded to 1–2000).

They drape on the globe on the OSM and Bing stacks and on the Google Photorealistic tileset on Google 3D (see `src/maps/imageryHost.js`). OpenRailwayMap and OpenInfraMap, also requested in #10, are not included: OpenRailwayMap's tile server only answers requests whose Referer is its own site, and OpenInfraMap serves vector tiles that need a vector rendering pipeline.

 - **DelDOT live video cameras.** The keyless `tmc.deldot.gov/json/videocamera.json` catalog supplies active cameras and official `https://video.deldot.gov/live/…/playlist.m3u8` links. The local server transiently buffers bounded MPEG-TS segments in memory and deletes them on session release or idle expiry. No recordings are retained. `CCTV_DELDOT_ENABLED=0` disables the pack. Public availability is not a blanket redistribution license; deployment beyond personal local viewing needs confirmation of applicable DelDOT terms.
 - **Fintraffic weathercams.** The camera list is one keyless GeoJSON request to `tie.digitraffic.fi/api/weathercam/v1/stations` (809 stations / 2,275 presets), sent with the `Digitraffic-User: gods-eye-view` header the service asks clients to identify themselves with and with gzip; frames are stills on `weathercam.digitraffic.fi`, refreshed on each station's 600 s collection interval, which is also the client's ambient-still refresh cadence for this pack (the active camera keeps the usual 10-second refresh). One preset (a fixed camera view) is one camera; stations not `GATHERING` and presets not `inCollection` are dropped. Attribution is required by the CC BY 4.0 licence and is registered in the Data attribution popover. `CCTV_FINTRAFFIC_ENABLED=0` is the kill switch.
 - **DriveBC highway cameras.** The camera list comes from the keyless `https://www.drivebc.ca/api/webcams/` endpoint served by the DriveBC.ca site ([bcgov/DriveBC.ca](https://github.com/bcgov/DriveBC.ca)); frames come from `https://www.drivebc.ca/images/<id>.jpg`, built from the numeric camera id. DataBC's [DriveBC HighwayCams](https://catalogue.data.gov.bc.ca/dataset/bc-highwaycams) catalogue entry publishes the same cameras under the Open Government Licence – British Columbia, but its CSV still lists the retired `images.drivebc.ca` frame URLs, which now return a placeholder. The licence's attribution statement is required and is registered in the Data attribution popover. By default the 250 cameras nearest Vancouver and Victoria load; `CCTV_DRIVEBC_MAX_SOURCES` changes the cap and `CCTV_DRIVEBC_ENABLED=0` turns the pack off. Some cameras in the feed are supplied by partners (TransLink, the City of Vancouver, the City of Surrey, Parks Canada / Alberta Motor Association and others); the feed's per-camera credit is carried onto the camera record and shown beside the provider in the CCTV panel.
-- **City of Ottawa traffic cameras.** Camera images come from the city's [Traffic Camera Images API](https://traffic.ottawa.ca/en/traffic-map-data-lists-and-resources/about-the-data), which requires an access certificate requested through the city's registration form and allows one certificate and user id to fetch a camera at most once every 60 seconds. Set `OTTAWA_CAMERA_CERTIFICATE`; without it the pack is skipped and makes no request. The camera list is the documented keyless `traffic.ottawa.ca/map/service/camera` JSON (camera number, English and French names, coordinates, owner). Frames are `traffic.ottawa.ca/opendata/camera?c=<number>`; the server adds the certificate and the user id `gev` at fetch time, so no catalog response carries the key, and serves each camera from one shared in-memory frame per minute. MTO cameras carried on the city feed keep their owner as a per-camera credit. The feed publishes no bearing, so headings use the shared id-hash fallback at low confidence, and no status field, so a camera the city takes offline still registers. Frames are never stored on disk. The city states no redistribution licence for the images; the certificate request asks how they will be used, so describe the deployment there. `CCTV_OTTAWA_MAX_SOURCES` caps the pack (default 250, nearest downtown) and `CCTV_OTTAWA_ENABLED=0` turns it off.
-- **World cams image subset.** The normal CCTV catalog adds 1,176 Oregon TripCheck stills and 1,054 MLIT river cameras from the curated `config/cctv_sources.world-image-cameras.json` export; disable it with `CCTV_WORLD_CAMERAS_ENABLED=0`. The export's Vegagerðin rows are left out because the Iceland pack already loads those cameras. The server validates and pins each image URL to its provider path, fetches a frame only when a camera is viewed, and never stores or redistributes it. [ODOT allows businesses, private citizens and organizations to use TripCheck images and asks for credit](https://www.tripcheck.com/Pages/Frequently-Asked-Questions) ("Camera courtesy of ODOT"); TripCheck also carries partner cameras run by Oregon counties and cities, Caltrans and WSDOT, which keep their owner's name in the camera label. MLIT's [site terms](https://www.river.go.jp/kawabou/kwb_apend/html/caution.html) follow the Government of Japan Standard Terms of Use 2.0 (CC BY 4.0 compatible, commercial use allowed, source credit required) and ask tools not to collect data periodically, pointing regular collection to the river information data service; frames are therefore fetched only on view and refresh at most every ten minutes per camera. Both credits are registered in the Data attribution popover.
 - **TxDOT ITS cameras.** The catalog comes from the keyless `its.txdot.gov/its/DistrictIts/GetCctvStatusListByDistrict` endpoint, one call per district. Frames come from the per-camera `GetCctvSnapshotByIcdId` endpoint, which answers JSON carrying a base64 JPEG rather than an image body; the proxy decodes it only for responses from the official TxDOT origin and validates the JPEG header before serving. Only cameras reporting `Device Online` are registered. Districts default to Austin and San Antonio (`CCTV_TXDOT_DISTRICTS`; 25 codes exist statewide); `CCTV_TXDOT_MAX_SOURCES` caps the pack and `CCTV_TXDOT_ENABLED=0` turns it off. Frames are fetched live at request time and are never stored or redistributed.
 - **Tallinn ristmikud.** Intersection camera stills are fetched live from `ristmikud.tallinn.ee` (`/last/camNNN.jpg`).

 - **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`.
 - **FL511 Florida cameras.** Off by default; set `CCTV_FLORIDA_ENABLED=1` to load them. The camera list is the keyless FL511 traffic camera layer on ArcGIS (`services.arcgis.com/.../FL511_Traffic_Cameras`), published from a Florida Division of Emergency Management account rather than by FL511 directly, and the service carries no licence text of its own. It is paged up to 2,000 rows at a time, ordered by the layer's object id and following ArcGIS's `exceededTransferLimit`, to cover the ~4,000-camera statewide set. Frames are stills on two Divas Cloud hosts (`images-dis.divas.cloud`, `snapshots.divas.cloud`); both are host-pinned and a row whose image resolves elsewhere is dropped. `CCTV_FLORIDA_MAX_SOURCES` caps the pack (default 500, anchored per region across the state). Each catalog page is read under a 2 MiB cap and redirects are refused. Frames are fetched live at request time and never stored or redistributed. FL511's terms (fl511.com/privacy#disclaimer) license its content for individual, personal use only; any other use, including a public deployment, needs FDOT's express written consent.
 - **Catalonia (Servei Català de Trànsit) cameras.** The camera list is the keyless `https://www.gencat.cat/transit/opendata/cameres.xml` WFS/GML feed, fetched over https with redirects refused and the body read capped at 1 MiB, since the list decides ids, coordinates and which allowlisted frame path is proxied. It carries a `font` field naming the real publisher per camera; this pack keeps SCT's own highway cameras plus hotlinked Barcelona (IMI) and Terrassa municipal cameras (~130 total), each confirmed to return a real frame, so frame URLs are checked against a small host allowlist (`mct.gencat.cat`, `www.bcn.cat`, `emap.terrassa.cat`) rather than one pinned origin (a link carrying `user:pass@` userinfo or an explicit port, or pointing outside that host's frame directory, is rejected even on an allowed host; an SCT `sctidcam` must be a bare `.gif`/`.jpg` filename), and every non-SCT camera carries its real owner as a `credit` shown beside the shared `provider`. The feed carries no compass heading, so every camera loads at low heading confidence (same as TfL and Fintraffic). SCT's own feed link (`RenderService`) needed a workaround: it always 302s to a second endpoint (`TransitCamera`) on a Location the upstream hardcodes as plain http even when requested over https — refused by `fetchWithinHost`'s same-origin (scheme-included) redirect policy — and separately, `mct.gencat.cat`'s TLS setup fails the handshake with Node's fetch outright (`ERR_SSL_WRONG_SIGNATURE_TYPE`) even though other HTTP clients complete it. The loader therefore builds the `TransitCamera` URL itself, over plain http, from `RenderService`'s `sctidcam` id, rather than registering the (broken) upstream link — the only transport this one host actually serves to this runtime. Camera ids are built from the SCT camera file or the partner image path, not the feed's `fid` (which embeds an upstream server-start stamp and changes on every upstream restart), and rows the feed lists more than once collapse to one camera. The feed carries no camera status field, so a camera its publisher has taken offline still registers and shows the publisher's own "image unavailable" still (SCT and Barcelona both serve one with HTTP 200), the same as other packs without a status field. Frames are fetched at request time and never stored or redistributed. The feed itself states no licence; the pack relies on the Generalitat de Catalunya open-data portal's terms for this dataset (the licence and attribution above). Disable with `CCTV_CATALONIA_ENABLED=0`.
-- **Iceland (Vegagerðin / IRCA) cameras.** The camera list is the keyless `https://gagnaveita.vegagerdin.is/api/vefmyndavelar2014_1` JSON feed (about 500 camera views at roughly 170 stations), fetched over https with redirects refused and the body read capped at 2 MiB, since the list decides ids, coordinates and which frame path is proxied. Frames are JPEG stills in `https://www.vegagerdin.is/vgdata/vefmyndavelar/`; only links inside that directory are registered (userinfo, explicit ports and encoded path separators are rejected). Camera ids come from the frame file name. The feed's `Skyring` view description is the camera label, and a stated facing ("til vesturs", "í suður", "séð austur") sets a high-confidence heading; a view that states none, or two different ones ("niður á veg", a bare road direction), takes the id-hash low-confidence pose. The feed has no elevation, so cameras carry a flat prior that the client's ground snap corrects. IRCA publishes road camera images under CC BY 4.0 and requires the licensor to be acknowledged without implying endorsement; the pack shows the attribution above (licensor, dataset, CC BY 4.0, terms link and no-endorsement note) in the Data attribution popover, and every camera record carries the licence string. IRCA describes the images as fetched several times per hour (a live frame's `Last-Modified` was about four minutes old on 2026-11-06) and the real-time data as provided as is, without warranty. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_ICELAND_ENABLED=0`.
 - **King County road cameras.** Keyless. The camera list is one public ArcGIS FeatureServer GeoJSON query (King County DOT Road Services, "King County and WSDOT Traffic Cameras"). The `outFields` list is explicit on purpose: the layer also carries asset-administration columns — including staff names — that are never fetched. Only live, active cameras with frames on the county's own `info.kingcounty.gov` image handler are registered (the feed writes `http://`; the handler serves HTTPS, so URLs are upgraded and pinned before registration). WSDOT-owned rows in the layer are skipped because their frames are WSDOT-hosted, outside the pinned image origin; partner-city cameras hosted on the county image handler (e.g. Newcastle) name their owner as the per-camera credit. The layer publishes no facing, so headings use the shared id-hash fallback at low confidence. Uniquely, the county publishes each camera's hardware `Manufacturer`/`Model` (Cohu 3950/3965, Bosch AUTODOME, Axis PTZ domes); both are carried on the source (and served by `/api/cctv/sources`) as `model` and `manufacturer` for identified-hardware consumers (vendor-generic strings such as `PTZ` name no model and are omitted). Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_KINGCOUNTY_ENABLED=0`.
 - **WSDOT highway cameras.** Keyless. The camera list is the Esri JSON layer `data.wsdot.wa.gov/travelcenter/Cameras.json` — the same layer WSDOT's own Travel Center map consumes (~1,700 point features, EPSG:3857 geometry converted to WGS84 on load; the body carries Windows-1252 bytes and is decoded as such). Only frames on WSDOT's own `images.wsdot.wa.gov` host are registered — the catalog also lists ~70 partner cameras (Oregon DOT, City of Seattle, lodges, airports) whose own terms apply, and those are skipped rather than proxied. WSDOT's layer metadata marks the feed for "low volume" use (see WSDOT's [travel information disclaimer](https://wsdot.wa.gov/about/policies/travel-information-disclaimer)). The catalog is fetched once per CCTV catalog refresh (every 15 minutes), and a camera's frame is fetched only when that camera is viewed; frames are never stored or redistributed. The live feed's `CompassDirection` is a single cardinal (N/E/S/W), `B` (both directions — most rows), `O`, or null. A single cardinal gives a high-confidence heading (the diagonals NE/SE/SW/NW are mapped too should they appear); `B`, `O`, null, and any other code carry no single facing and use the shared id-hash fallback at low confidence. By default the 250 cameras nearest Seattle and Spokane load; `CCTV_WSDOT_MAX_SOURCES` changes the cap (8–1,200) and `CCTV_WSDOT_ENABLED=0` turns the pack off. A keyed WSDOT Traveler Information API serves the same population for higher-volume use and is deliberately not required here.
 - **Hong Kong Transport Department traffic snapshot cameras.** Keyless. The English camera list is the public DATA.GOV.HK XML at `static.data.gov.hk/td/traffic-snapshot-images/code/Traffic_Camera_Locations_En.xml`; frames are stills on `tdcctv.data.one.gov.hk`, and only that host is registered. Frame URLs are rebuilt from each camera key (`https://tdcctv.data.one.gov.hk/{KEY}.JPG`) rather than taken verbatim from the catalog. Stills were probed to answer directly on that origin with no redirect hop. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. By default nearly the full catalog loads (~1,013; pack cap 1,100), prioritized nearest Central, Tsim Sha Tsui, Sha Tin, Tsuen Wan, Tai Po, Fanling, Tuen Mun, Yuen Long and Tseung Kwan O so a lowered cap still spans Hong Kong Island, Kowloon and the New Territories. When the sum of packs exceeds the catalog-wide ceiling, shared round-robin keeps every lane represented. `CCTV_HK_MAX_SOURCES` (8–1200) changes the cap and `CCTV_HK_ENABLED=0` turns the pack off.

-Operator, owner country and purpose for active satellites, keyed by NORAD number, from the Union of Concerned Scientists Satellite Database release **UCS-Satellite-Database 5-1-2023** (data current through 2023-05-01; https://www.ucsusa.org/satellite_database). The satellites layer joins it to CelesTrak positions and SATCAT records to file each satellite as a station, imaging, telecom, Starlink, probe or debris object, and to name its operator and owner. Section 3 of the UCS database manual: "The Database is free and its use is unrestricted. We request that its use be acknowledged and referenced in written materials. References should include the version of the Database that was used, which is indicated by the name of the Excel file, and a link to or URL for the webpage www.ucsusa.org/satellite_database." The app acknowledges it in the Data attribution popover. UCS has paused updates since this release; Starlink rows are dropped (Starlink is classed by name).

-Swath widths and ground resolutions for 46 Earth-observation platforms (Landsat, Sentinel, MODIS, VIIRS, GOES, Himawari, Gaofen, CBERS, RADARSAT, TerraSAR-X, COSMO-SkyMed, ALOS, KOMPSAT, SPOT, Pléiades, WorldView, SkySat, PlanetScope, ICEYE, Capella, Umbra and others), compiled 2026-11-04 from the operator and agency pages cited per entry. The orbital view draws each satellite's sensor swath to scale and caps its zoom at that swath. Facts only; no text or images copied. A swath is confirmed on an operator, agency (ESA's eoPortal included) or academic page; resellers are not cited. The CEOS MIM Database (CC BY 4.0) is not yet used.

 The data proxies under `server/providers/` are written so the browser cannot turn the server into an open relay:
 
 - **No arbitrary-URL fetching.** The CCTV frame proxy fetches only server-registered camera/frame URLs — clients cannot pass an upstream URL to fetch (SSRF mitigation). Other proxies target fixed upstream hosts.
-- **Live HLS is bounded and origin-pinned.** Registered HTTP(S) HLS sources use a Node puller that rejects redirects and off-origin playlist references, bounds playlists to 256 KiB and segment bodies to 8 MiB while streaming, and aborts timed-out or released sessions. At most two sessions retain 12 segments/24 MiB each, plus bounded download buffers. Stores are memory-only and idle sessions expire after 15 seconds. RTMP/ffmpeg execution is not enabled. Locally configured source URLs remain an operator trust boundary.

At most two sessions retain 12 segments/24 MiB each, plus bounded download buffers. Stores are memory-only and idle sessions expire after 15 seconds. RTMP/ffmpeg execution is not enabled. Locally configured source URLs remain an operator trust boundary.
 - **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.
-- **Québec 511 video plays in the browser, opt-in and after Play.** With `CCTV_QUEBEC_VIDEO_ENABLED=1`, `/api/cctv/sources` lists, for each MTQ camera, one URL built server-side from its numeric id on `https://www.quebec511.info/Carte/Fenetres/camera.ashx`; the overlay accepts no other host, path or format. The browser loads that clip only after the viewer presses Play for the selected camera, so Québec 511 sees the viewer's IP address, and the panel says so before Play. Selecting a camera by click, auto-hop, a scene or voice never loads it, and switching cameras stops playback. GEV never proxies, caches or reads the video's pixels. With the flag unset (the default) the browser makes no request to Québec 511.
 - **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/<id>` 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.
 - **Local receiver feeds are operator-configured and local-only.** `/api/local-receivers/aircraft` reads only the `aircraft.json` URLs in the server's `LOCAL_RECEIVER_FEEDS`; the browser never supplies an address. Each host must pass the shared tap address rule (`src/data/tapAddress.js`: loopback, RFC1918, `localhost`, `*.local`; no link-local, IPv6 or other names), the scheme must be http(s), the path must end in `aircraft.json`, and credentials, queries and fragments are refused. Invalid entries are logged at startup and never fetched. Reads use a 2 s timeout, refuse redirects, cap bodies at 2 MB and share one read per second; responses name each feed by band only and never carry upstream error text.
 - **Voice place search runs only on the operator's Overpass.** `/api/osm/features` answers only when `OVERPASS_UPSTREAMS` is set and never falls back to a public instance. The client sends a curated preset id, a box, a mode and a limit; the server writes and quotes the Overpass query itself, so no client or model text reaches it. Boxes are capped (36 deg² for a count, 4 deg² for a listing), as are the feature limit, the Overpass timeout and memory, and the response bytes read. Each client (IPv6 clients keyed by /64, as on `/api/overpass`) runs one search at a time and two run at once in all, under a per-client rate limit (12/min) and a global one (30/min); a search gets 22 s across every configured endpoint in turn (Overpass itself is told 20 s), which ends before the voice answer stops waiting at 25 s. The route sits behind the cross-site gate below. Answers are cached in memory and on disk (`.gev-cache/osm-features/`, at most 400 entries and 256 MB, kept a day), keyed to the configured instance so a repointed `OVERPASS_UPSTREAMS` never serves the old one's answers; a malformed answer is never cached.
-- **Validated response formats.** Proxied bodies are relayed only in the format the route serves. CCTV frames and the Street View fallback accept JPEG, PNG, GIF, WebP and AVIF only, sent under their canonical type; any other type falls through to the next fallback. The one exception is a source registered as an MJPEG still (the Taiwan Highway Bureau feeds): its `multipart/x-mixed-replace` answer is read only up to its first JPEG part, capped at 2 MB, and sent as `image/jpeg`; a multipart answer from any other camera falls through. A camera whose API needs an operator credential (the City of Ottawa certificate, `OTTAWA_CAMERA_CERTIFICATE`) has a keyless catalog URL; the frame proxy adds the credential only at fetch time, only for a URL inside that camera's pinned path, so `/api/cctv/sources` and `/api/cctv/stream` never carry it. Live CCTV media must match its feed kind (`video/mp4`, `video/webm`, or `multipart/x-mixed-replace` with a boundary) before it is relayed or the camera counts as healthy, and its redirects stay on the registered origin. GBFS bodies must parse as JSON and are re-serialized as `application/json; charset=utf-8`. Camera catalog URLs are pinned by parsed URL — scheme, exact host, no credentials, default port, and a normalized path inside the agency's image directory — and a redirect on a pinned host must stay inside the same directory. Every `/api/cctv` route uses the keyless cross-site checks described below, so cameras stay reachable behind a reverse proxy; a request carrying forwarding headers never reaches the key-bearing Street View fallback and gets the placeholder frame instead, as when no key is configured.

-# CCTV integration workflow
-
-Use this workflow when adding a camera provider or repairing an existing feed.
-The CCTV catalog comes through the local server; media normally does too. Keep
-provider-specific URL policy on the server, including any validated browser-only
-media URL permitted by the exception below.
-
-## 1. Check the source before coding
-
-- Identify the catalog endpoint and the actual frame or live-media endpoint.
-  They may be different hosts or use different formats.
-- Read the provider's license, terms, attribution, rate limits, and access
-  requirements. Publicly reachable data is not automatically licensed for
-  reuse. Record whether the app may display it and whether any use is
-  restricted.
-- Prefer a public, keyless feed. If credentials are required, keep them in a
-  server-only environment variable; never put a secret in browser code or a
-  Vite-exposed variable. A pack that needs a key is opt-in by that key: with
-  the variable unset it makes no request and logs once (Ontario 511 and
-  Ottawa). Keep the key out of catalog URLs and add it only at fetch time. Use
-  the provider's documented API, not a website endpoint that skips its key. If
-  access terms require an agreement or remain unconfirmed, make the pack
-  opt-in and ensure it makes no request by default.
-- Confirm the feed can be fetched from the app's Node server environment. A URL
-  opening in a browser does not prove the server can reach it, and browser CORS
-  behavior does not diagnose a server-side fetch.
-- Treat camera directories and aggregators such as [TW Live](https://tw.live/)
-  as discovery aids. Trace each listing to the original agency or camera owner;
-  their data and media terms govern reuse. For example, SkylineWebcams says
-  only camera hosts may embed its live feed and its terms restrict copying or
-  retransmitting footage, so do not proxy its stream without written
-  authorization ([FAQ](https://www.skylinewebcams.com/support/faq.html),
-  [terms](https://www.skylinewebcams.com/en/terms-of-use.html)).
-- Decide whether the provider supplies still snapshots or continuous video.
-  Prefer stills unless live video is necessary and supported by the existing
-  proxy path.
-
-## 2. Add and register the provider pack
-
-Use the smallest existing provider as a template. Current owners are:
-
-- `server/providers/cctv/sources.js` for standard open-data loaders.
-- `server/providers/cctv/<provider>.js` for a provider with its own parser,
-  fallback, or more involved URL policy.
-- `server/providers/cctv/catalog.js` to import the loader and add it to
-  `LIVE_PACKS`. Each pack is independently gated and the shared catalog cap
-  allocates space across packs.
-- `server/providers/cctv/constants.js` for provider endpoints, caps, and
-  timeouts.
-
-Return normalized camera records with stable unique IDs, readable names,
-`city`/`cityId`, provider attribution, valid `lat`/`lon`, and the correct
-`feedType`. Include camera heading only when the source actually provides a
-bearing; descriptive direction text is not a numeric heading. Mark uncertain
-heading data with the existing low-confidence conventions. Set `sourceKind` so
-health and source diagnostics identify the provider. Apply a bounded per-pack
-camera limit and geographic filtering where appropriate; avoid one provider
-silently consuming the whole shared catalog cap.
-
-Camera coordinates need their own verification. Prefer the original provider's
-camera coordinates, then corroborate them against its location description,
-route/mile marker, or official map. An aggregator's map dot, a town/county name,
-or a geocoded attraction name is not a precise camera position. Do not pin a
-camera to a city center or nearby landmark; if its actual location cannot be
-verified, leave it out until it can. For manually curated coordinates, record
-the evidence in the provider data or an adjacent comment. For example, TW Live
-camera pages identify the originating agency; use that agency's catalog for
-the camera point when available.
-
-If the source becomes opt-in, use the catalog's opt-in gate (`envOptIn`) and
-document the flag and reason in `DATA_SOURCES.md`. Otherwise use the normal
-enabled-by-default flag pattern and document how to disable the pack.
-
-## 3. Keep frame and media requests server-registered
-
-The browser should request the local `/api/cctv/frame/:id` or
-`/api/cctv/media/:id` endpoint. Do not pass an arbitrary upstream URL from the
-browser, and do not fetch an unvalidated URL supplied by a catalog record.
-Every provider must have a server-side rule that pins frame and media URLs to
-the expected scheme, host, and path; use HTTPS where the provider supports it.
-Use `pinnedCameraUrl()` for URLs that belong under a fixed provider directory,
-or a stricter provider-specific validator when hosts or paths vary. Register
-any new permitted image/media origin in the existing
-`server/providers/cctv` media policy.
-
-Catalog and media loaders must also:
-
-- refuse unsafe schemes, credentials, unexpected ports, redirects outside the
-  registered origin/path, and malformed identifiers;
-- set request deadlines and cap catalog and buffered frame bodies;
-- parse only the expected format and validate coordinates before returning a
-  camera;
-- handle offline cameras and partial provider failures without failing the
-  entire merged catalog; and
-- avoid persistent frame storage unless the provider's terms explicitly allow
-  it and the design has been reviewed.
-
-For live media, prefer the existing proxy and supported feed type (`mjpeg`,
-`mp4`, `webm`, or `hls`). A direct browser-only video is a narrow fallback for
-a source whose terms allow embedding when the browser can play it but the app
-server cannot fetch it. Unconfirmed embedding terms make it opt-in like any
-other pack, and the browser loads it only after an explicit play action, never
-on selection, because the provider sees the viewer's IP address. Build its URL
-from a validated provider ID on the server; never accept a browser-supplied
-media URL. Render it in a native DOM
-`<video>` without `crossOrigin`, and do not read its pixels into canvas, WebGL,
-or a Cesium texture. If a map preview is needed, a second video request may be
-paused as a DOM overlay at the camera location; label it as an approximate
-still and scale it with map distance. If terms disallow embedding, use a source
-link instead. Read [SECURITY.md](../SECURITY.md) before changing URL
-validation, redirects, or proxy behavior.
-
-When an image provider sets a minimum refresh interval, enforce it at the
-server frame boundary as well as in the client. A bounded in-memory cache and
-single-flight request per camera prevent projection, panel, and re-selection
-paths from multiplying upstream requests; do not persist frames unless the
-provider's terms explicitly allow it.
-
-## 4. Add focused regression coverage
-
-Add provider tests under `src/data/` following the existing CCTV test naming
-and fixtures. Cover at least:
-
-- representative valid catalog rows and their normalized output;
-- missing or invalid IDs, coordinates, and frame URLs;
-- duplicate records and the pack's cap/filter behavior;
-- unsafe host/path, credentials, and redirect cases;
-- timeout, oversized, malformed, and unavailable upstream responses; and
-- the frame or live-media content type the provider actually serves.
-
-Use `src/data/cctvProxy.test.mjs` for shared proxy/media behavior and
-`src/data/cctvCatalogCap.test.mjs` for shared catalog allocation. For a
-browser-only source, verify native playback, denied canvas pixel access, the
-paused second-player overlay, and its cleanup separately from proxy tests. Run
-the focused provider and proxy tests, then the standard checks from
-[CONTRIBUTING.md](../CONTRIBUTING.md) that apply to the change. For runtime
-verification, inspect `/api/cctv/sources`, `/api/cctv/health`, and the camera's
-`/api/cctv/frame/:id` or `/api/cctv/stream/:id` response locally. Confirm a
-successful frame is from the upstream camera by checking its content type and
-`X-CCTV-Source`; a fallback image is not proof that the upstream feed works.
-
-## 5. Update source documentation and submit
-
-- Add the provider, endpoint, terms/license, required attribution, key status,
-  caching behavior, and any restrictions to `DATA_SOURCES.md`.
-- Update the CCTV source section in `docs/CURRENT-STATE.md` when runtime
-  behavior, flags, caps, or fallback behavior changes.
-- Register in-app attribution through the existing source/provider credit
-  fields; update `src/data/dataCredits.js` when the source needs a layer-level
-  credit.
-- Add the required `changelog.d/<pr-number>-<slug>.md` entry for a runtime
-  change, and include the source, license, attribution, key/runtime-fetch
-  details, and verification evidence in the PR description.
-- For a new layer, also follow the camera/source requirements in the
-  [new-layer PR checklist](../CONTRIBUTING.md#adding-a-new-layer).

-### Ship bridge view
-
-With no aircraft tracked, Cockpit can ride the selected AIS vessel instead.
-Entry needs only the layer of the vessel it rides, Live AIS Vessels, and a
-selected vessel; Contacts and every other layer may be off, before or during
-the bridge (`bridgeEntryAllowed` in `src/contextModePolicy.js`). A Context mode
-change still in flight blocks entry until it settles. Double-clicking the
-selected vessel enters it, and the entry button reads BRIDGE with a ship icon
-both in Contacts (`#cockpit-entry`) and under the selected vessel's Intel HUD
-readout in the bottom-right corner (`#cockpit-entry-readout`, shown with the
-HUD on, in its Tactical and Cyber layouts). Turning Live AIS Vessels off ends
-the bridge: the layer then has no subject (`getCockpitSubject` returns null).
-The bridge picture uses AIS alone, so no other feed being off makes it partial.
-Voice (`control_cockpit`) and the selection entry transaction stay aircraft-only;
-voice `enter` on a bridge or in an orbital view is refused before it touches
-tracking, with the reason to exit it first.
-The vessel layer supplies the subject (`getCockpitSubject`), hides that ship's
-sprite, card, detection bracket and trail while it is held
-(`setCockpitSubject`), and
-ignores scene clicks so open water cannot deselect it. The eye sits on the AIS
-position at a representative bridge height for the AIS type family
-(`src/layers/vessels/cockpitSubject.js`: cargo and tanker 30 m, passenger 25 m,
-tug 7 m, fishing 6 m, ferry and AIS "Other" (codes 90–99, or a feed's text
-type "Other") 4 m, sailing and pleasure 3 m; 12 m when the type names no
-family, including the reserved and wing-in-ground codes the vessel layer also
-files under OTHER), pitched 2° down with 2 m clearance over the shared ground floor
-(`src/cockpitSubjects.js`). The camera faces true heading (course over ground
-when heading is missing) and moves along course over ground. A ship reporting
-neither has no direction: the camera keeps the heading it had on entry, the
-heading readout shows `---`, the visor reads NO HEADING · AIS, the entry signal
-names the ship without a heading, no bow or stern mark is drawn, and the eye
-stays on the fix rather than moving along a made-up course. The vessel layer
-redraws a ship only on its 60-second refresh, so the camera's target is the last
-fix dead-reckoned along course over ground for up to 180 s, and the existing
-inertial anchor absorbs each new fix. The fix's age is read without comparing
-the two clocks (`vesselFixAgeSec`): the time since this client first received
-the fix, plus how far it trailed that refresh's newest fix, so a client clock
-running fast or slow neither projects the ship nor marks it stale, and a fix
-the feed keeps re-serving from its cache goes on ageing into STALE FEED. A
-stale vessel, or a projection past that limit, holds the camera on the target.
-The vessel layer floats ships on the geoid, which on a river or lake can lie
-well below the water (the Seine through Paris is ~27 m up), so the bridge also
-reads the rendered surface around its ship: the ship's position and a ring of
-eight probes 30 m out, the lowest probe taken as the water when it is 2 m to
-4,000 m above sea level. The first read starts from the tiles already loaded, then
-the full-detail read replaces it; it repeats every 5 s. Only one full-detail
-read runs at a time: while one is still running, a refresh reads the loaded
-tiles instead, and the slow read applies whenever it lands. Once a
-full-detail read has answered, loaded-tile reads no longer change the height;
-before then they may find raised water but never take it back to the sea.
-A read that sampled nothing, or failed, keeps the height it had and is
-tried again on the next refresh.
-
-The HUD keeps its frame, vision styles, briefing, weather and Display/Radio
-utilities. It names the ship, reads `{type} · LIVE AIS · EYE {height}`, shows
-speed over ground in knots, true heading and course over ground in place of
-altitude, hides the altitude tape, and shows the crew-entered AIS destination as
-a Reported Voyage card without an origin or direction arrow. The arrow keys
-look around the bridge in 5° steps (Shift for 45°): Left and Right turn the
-view all the way round, Up and Down pitch it up to ±90°, and the camera eases
-there unless the user prefers reduced motion. Home or `0`, or the LOOK AHEAD
-button shown while the view is turned, bring it back over the bow at the rest
-pitch. The keys stay with a focused text field, slider, tab, radio group, list
-or menu. The heading tape is a straight strip that scrolls continuously with
-the camera, so the caret reads the view's exact heading, while the readout
-above it keeps the ship's true heading; a ring with a centre dot marks the bow
-(prograde) and a ring with a cross the stern (retrograde) at their bearings
-from the caret. The bridge radar
-shows nearby AIS ships heading-up and opens at 3 NM
-(`DEFAULT_RADAR_RANGE_NM` in `src/cockpitRadar.js`); its range button steps
-3, 6, 12 and 24 NM and the chosen range is kept across bridges. Own ship
-sits where the camera rides (its fix dead-reckoned) and contacts at their
-last fixes, where the vessel layer draws them, so the scope matches the view
-out of the window. Contact
-Previous/Next and Live Signals aircraft handoffs are refused on the bridge and
-the Contact card stays hidden. Exit returns the camera to the vessel's map view
-through the layer's own focus. Tracking an aircraft or losing the vessel
-selection ends the bridge without refocusing the ship. `src/ui/cockpitBridge.test.mjs`
-covers entry, readouts, refusal and exit.
-
-### Orbital view
-
-With a satellite tracked and no aircraft tracked, Cockpit can ride the
-satellite instead. Entry needs only the Satellites layer
-(`orbitEntryAllowed` in `src/contextModePolicy.js`); Contacts and every other
-layer may be off. A Context mode change in flight blocks entry until it
-settles. Debris (rocket bodies, fragments and dead satellites; see the
-satellite class toggles) can be tracked but never entered: no ORBIT entry is
-offered and double-click refuses it. A tracked aircraft still takes
-entry first, and a tracked satellite
-takes it before a selected vessel. Double-clicking the tracked satellite
-enters it, and the entry button reads
-ORBIT with a satellite icon in Contacts (`#cockpit-entry`) and under the Intel
-HUD readout (`#cockpit-entry-readout`). Voice (`control_cockpit`) stays
-aircraft-only; its state reports an orbital view in use as a `satellite`
-subject. `gev:cockpit-mode-changed` carries layer `satellites` and the NORAD
-id.
-
-The camera sits on the satellite's own per-frame SGP4 position
-(`getCockpitPosition`, the sample the dot uses) and looks at the Earth's
-centre track-up: the ground track points to the top of the frame, so the
-picture scrolls along it (`nadirOrientation` in `src/cockpitOrbital.js`). A
-satellite with no ground track (a geostationary one) is shown north-up, and
-over a pole the previous frame's up is kept. It updates on every rendered
-frame, with no ground clamp. Entry opens in the plain optical vision style
-(the other styles stay one click away) and leases the map for flat imagery:
-with Google 3D tiles shown, which stay coarse from hundreds of kilometres up,
-the map switches to Esri imagery, and exit puts it back unless the operator
-picked another map meanwhile; another owner already holding the map (an
-imagery comparison) keeps it as it is. While orbit holds the lease, Recent
-Imagery cannot take it: turned on in orbit, the layer reports the comparison
-in use until, after exit, it is turned off and on again or its shown days
-are cleared and picked again. The Cockpit cloud pass is off in orbit
-(it fades out above 24 km); cloud cover from orbit is the Weather layer's,
-and the saved cloud preference stands for the next aircraft or bridge. The layer hides the satellite's dot, docked
-companions, its own orbit ring and its detection bracket, and draws every
-other orbit ring (the ISS ring included) at 30% of its alpha; other
-satellites' points and labels stay. Scene clicks and the layer's Escape are
-ignored by the satellites layer while it is ridden (a click on a mapped
-site focuses it; see below). The optical zoom steps 1×, 2×, 4× and 8× for
-every satellite with `+` (or `=`) and `-` (or `_`), the panel's buttons and
-the mouse wheel (one step per notch; trackpad scrolling is summed to a step):
-the 1× frame is 60° vertical in low orbit and fits the Earth's disk with
-margin from high orbits, each step divides the tangent of the half-angle, and
-Cesium's `frustum.fov` is set from it for the canvas aspect. A step animates
-over 400 ms with a focus-pull blur and a reticle lock tick, and cuts at once
-under `prefers-reduced-motion`. An imaging satellite matched to an entry of
-the bundled sensor pack (`src/data/local_data/imaging_sensors/`, by NORAD
-number or name in `src/layers/satellites/sensors.js`) whose narrowest swath
-is confirmed also gets 16×, 32×, 64× and 128×, each only while the view at
-the satellite's live altitude and the window's shape is still at least as
-wide as that swath (`orbitalMaxZoom` in `src/cockpitOrbital.js`); when the
-cap falls below the zoom shown, the view steps back to it. Unconfirmed
-swaths add no steps, but are still drawn, read out and offered to SENSOR.
-The sensor's swath is drawn to scale as a strip along the ground track (its
-width follows the view through a zoom step, not ahead of it) with
-a SENSOR SWATH readout, and a SENSOR button zooms to exactly that width when
-it lies between 1× and the cap. No strip is drawn for a geostationary view
-(no ground track; its sensors image areas, not strips) or a SAR (it images
-to one side of nadir, not under it); the readout stays. Tilted off nadir
-the strip stays (view and swath widen alike), the readout scales as the swath
-readout does (`SENSOR SWATH ≈ 191 KM`), and SENSOR, a nadir framing, is
-hidden; tilted past the Earth's limb neither the sensor nor the swath
-reads. A swath is confirmed only on the operator's, an agency's (ESA's
-eoPortal included) or an academic page for its platform. From
-16×, with flat imagery on the globe (not Google 3D tiles) and the view at
-nadir, every 2 s the view asks the base imagery layer for the tiles it will
-need 5 to 20 s ahead along the ground track (`prefetchImageryAhead` in
-`src/ui/cockpitOrbitalView.js`), so the browser has them cached when the
-view arrives. The level is the one Cesium will draw there
-(`imageryLevelForView` in `src/cockpitOrbital.js`, following Cesium's own
-choice: the terrain level whose error spans at most the globe's maximum
-screen-space error, then the imagery level whose texels are nearest that
-error, about one to two screen pixels per texel). It asks for at most 12
-tiles at a time through Cesium's request scheduler, throttled per server and
-at the lowest priority, so a request is declined while the imagery server's
-slots are taken by the tiles on screen and is the first dropped when the
-scheduler is full (a declined or dropped tile is asked for again later, one that failed to load is not); it remembers the last 512 tiles asked for and does not ask
-for those again, starts over on another base map (cancelling the old map's
-pending requests), and cancels the requests still pending on exit. Across the track it samples the centre line, a third
-out and the frame's edges. While tilted off nadir the view looks away from
-the track, and with the world clock more than a minute from now (paused or
-played back) it will not pass where the look-ahead points, so nothing is
-pre-loaded. The arrows tilt the view off nadir in 5° steps
-along the frame's axes (Up/Down tilt forward/aft along the ground track,
-Left/Right across it, each axis to ±45°; Shift takes no larger step); Home,
-`0` or NADIR return to nadir. While tilted the panel shows the total angle
-from nadir, acos(cos along · cos across), before each axis
-(`OFF-NADIR 18.0° · FWD 10° · RIGHT 15°`; N, S, E and W for a north-up view)
-and a NADIR button, and the swath readout turns approximate
-(`SWATH ≈ 26 KM`): an estimate of the ground width at the view's centre, the
-nadir footprint scaled by 1/cos² of the tilt across the frame and 1/cos of
-the tilt along it (`offNadirSwathScale`, flat Earth). At nadir it reads the
-footprint without ≈. After a zoom step lands, the focus pull holds until the
-imagery under the view has loaded (at most 2.5 s, `zoomSettleHolding`), then
-the reticle locks. The look keys and zoom keys keep the bridge's focus
-guards.
-
-In orbit the briefing's Live Signals page (OBSERVED / MAPPED PINGS) lists
-what is around the satellite, as the aircraft Cockpit lists the contacts
-of its Contacts snapshot (`src/ui/cockpitOrbitalSignals.js`): five rows at
-most, rebuilt once a second with stable keys, so a row keeps its place and
-time. TRACK ACQUIRED stays first. Then:
-
-- **Sites**: the Mapped Installations layer's loaded records around the
-  sub-satellite point (`getNearby`, asked only as far as the reach extends
-  over the ground, and never past 3,000 km, so from a high orbit only the
-  sites within 3,000 km of the point below are listed) that face the
-  satellite and lie within the off-nadir reach, nearest to nadir first, the focused site always among them. A row
-  reads the site's name over its class and off-nadir angle; its button
-  (`Keep the camera on …`) focuses the site, and on the focused site's row,
-  marked as the subject is (`FOCUS · …`, `Release the camera from …`), ends
-  the focus. With Mapped Installations off the layer keeps its records, so
-  nothing is listed then: a SITES STANDBY row says to turn the layer on.

-  left out (the satellites layer's bounded `getNearestPositions`, measured
-  from the satellite itself), with their bearing from the top of the frame
-  and distance. A row (`Ride …`) rides that satellite. While there is a

-  that satellite has left the catalogue it is dropped and RETURN offers the
-  one before. Riding stays in orbit: the satellites layer tracks the new
-  satellite (`trackById`), the Cockpit takes the camera back at once and
-  marks it as the ridden subject, any ground focus ends with the view easing
-  back to nadir, and the camera hops to the new satellite along the great
-  circle over 1.2 s (cut under reduced motion), keeping the zoom. Until the
-  camera is on the new satellite the page shows only TRACK ACQUIRED and
-  RETURN (and SITES STANDBY with Mapped Installations off), then rebuilds
-  at once. The new satellite's TRACK ACQUIRED carries the time it was
-  ridden. The hop starts from where the camera was, which does not follow
-  the old satellite on.
-
-Sites take two rows while satellites fill the rest, more when there are
-fewer satellites. The Contact card stays hidden in orbit.
-
-The focus (`src/ui/cockpitOrbitalFocus.js`, geometry in
-`src/cockpitOrbitalFocus.js`) aims the look each frame from the satellite's
-position to the site's Earth-fixed position in the same track-up nadir
-frame the arrows tilt, so the site stays at the centre as the satellite
-moves. The turn onto it (and between sites) eases what is left of the swing
-with the arrows' easing on a slower clock (250 ms time constant, about
-0.75 s to 95%), then holds the site exactly, and cuts under
-`prefers-reduced-motion`. A single click on a site's marker focuses it too:
-the pick is resolved through the layer's own pick ids (`findByPick`: a named
-marker's `{ installationId }` or a site entity). A click anywhere else
-(a site beyond the reach included), the
-focused site's row, NADIR, Home or `0` ends the focus and the view eases
-back to nadir on the same clock; an arrow ends it (or the ease back) and
-tilts on from where the view is. The layer reloads its thinned view as the
-camera moves (about once a second in orbit), so a site in view can leave
-its records for a moment: while the layer is on, a site seen in the last
-10 s stays a candidate (sites do not move), so the rows hold still and a
-row's site can be focused, and a focused site keeps its last position. The focus ends by
-itself, easing back, when the site leaves the reach (either tilt axis past
-±45°, or the site below the satellite's horizon), when the layer is turned
-off, when another satellite is ridden, and with the orbital view. A site
-beyond the reach cannot be focused. While focused the readout gives the
-single off-nadir angle to the site, as image metadata does
-(`OFF-NADIR 23.4°`, updated on the HUD's beat and not announced), names it
-in a polite live region (`FOCUS · Camp Alpha`), and the swath reads
-approximate as for a tilt, scaled by the tilt onto the site. Clicks still
-reach Cesium's own handler and never untrack the satellite; a click a tool
-owns (drawing) is ignored, and the draw tool still borrows the click while
-it draws. A double-click on a site keeps or starts the focus on it and
-never reaches Cesium's double-click, which would track the site and end the
-view (the Cockpit's double-click routing in `src/ui/cockpitInput.js`); any
-other double-click goes on as before. `src/ui/cockpitOrbitalFocus.test.mjs`
-covers the rows, the easing in and out, the reach release, switching sites
-and satellites, the hop, the layer turned off, click handling and the
-readout, against the layers' method shapes.

-The HUD (`#cockpit-hud[data-subject='satellite']`, body class
-`cockpit-orbit`) mounts `CockpitOrbital` over the picture: name, class,
-altitude, orbital speed, sub-satellite point, TRACK UP (NORTH UP without a
-ground track) with a pointer that turns to keep north marked N on the frame,
-zoom and swath. Under
-the vision selector a "CURRENTLY OVER" band names what the sub-satellite point
-is over, looked up offline from the bundled Natural Earth packs
-(`src/data/placeBelow.js`: on land the first-level division as Natural Earth
-names it and the country in the reader's language through `Intl.DisplayNames`,

-the view's smaller side, so it is in the picture, "Sichuan, China · near
-Chengdu", from a bundled pack of Natural Earth populated places loaded on

-else the ocean; nothing in a coastline gap), at most every 2 s and only after
-20 km of ground travel, or at once when a zoom step changes how much ground
-the view shows. A division or populated-places pack that fails to load drops
-only that part (the country still shows); a lookup that fails outright hides
-the band rather than leave the last place up, and the next HUD beat looks

-Timiș, Romania. To use it, set `CCTV_SOURCES_FILE=config/cctv_sources.romania.json`
-in the local `.env` and restart the server. Set `CCTV_FORCE_AUSTIN=1` as well to
-retain the built-in live packs; despite its historical name, this flag applies
-to all live packs. The default catalog is unchanged.
-
-The camera uses Webcam Romania's public HLS stream and JPEG snapshot, fetched
-at runtime without an API key. Its position, 45.70028947266781, 21.233675914004227,
-was corrected by the contributor rather than copied from the directory's
-inaccurate pin. Heading, pitch, field of view, mounting height and ground
-elevation are uncalibrated priors; the camera retains the RAW PRIOR badge.
-See `DATA_SOURCES.md` for attribution and provider terms. Webcam Romania's
-terms grant no reuse licence for the video and name no camera operator; the
-provider's sanctioned route is its iframe embed. Keep this pack to local use
-and off hosted deployments unless the operator grants permission.
-
-The existing HLS puller resolves same-origin relative master/media references
-and serves local leased playlists and segments. It downloads complete segments
-without forwarding a browser Range header. Its per-segment streamed-byte cap
-is 8 MiB: Giroc's roughly ten-second 2702×1520 segments can exceed the former
-4 MiB cap (one measured 6,437,120 bytes). Retained data remains capped at
-24 MiB and 12 segments per session, with two sessions maximum. Redirect

 - Context is set for reading in every theme: mode, standby and action labels are 10 px, and the panel draws no glow halo. Outside Cyber, the two modes form one segmented control, the standby guidance is plain left-aligned text rather than a dashed placeholder, and the panel's section titles share the side panels' dock-label colour. Cyber keeps its separately framed mode buttons, its red panel titles, and in layout-focus a framed, centred standby card over its radar art.
 - The expanded desktop header omits the redundant `ON` label; the active mode button carries state. Expanded Contact results also omit the duplicate `GLOBAL CONTEXT` / `CONTEXT ONLY` status row and begin with the selected subject and its 250 km scope. Global Context does not fabricate a selected-entity model preview: the provisional hand-authored aircraft wireframe was removed because it was not geometry extracted from the selected entity's actual asset.
 - Dependency ownership is reversible: disabling Global Context releases only dependencies it enabled, while user-enabled layers remain on. This also removes the Military-layer suppression handoff when Global Context owned Military, allowing an already-enabled civilian Flights layer to resume its normal mixed rendering. If OpenSky is unavailable and has no last-good cache, Flights requests a capped 250 nm adsb.lol point snapshot around the current view anchor and labels that provenance explicitly; it never relabels military-feed rows as civilian data. If both inputs fail, Flights remains `UNKNOWN`.
-- Space Missions is replay-isolated: Rocket Launches and Satellites are the only Data Layers permitted while the mode is active. Direct UI and voice entry capture the same pre-entry snapshot; internal dependency and restoration enables do not create a user-owned Context session. Entry waits for incompatible layers to shut down, direct incompatible enables are blocked before lifecycle work, and the entry gate remains active through the complete Rocket Launches enable. That enable includes the first mission-index load: an HTTP error, timeout, network failure or malformed payload before any index has loaded fails the enable, so Context rolls back to the pre-entry layers instead of committing an empty, isolating mode; the camera returns to its pre-entry view unless navigation took it, and a toast says the mission index could not load. A valid empty index still enters, and a refresh failure after an index loaded keeps its records and the mode. Exiting cancels the layer's own camera flights but never one navigation started. A newer same-target ON request takes ownership of the pending entry without releasing its isolation snapshot, including when it arrives while the prior request is awaiting the adoption guard. A caller abort, resource cancellation, newer OFF, or layer teardown waits for exact manager settlement and restores that snapshot without resurrecting Rocket Launches. If an abort lands after only part of a restore settles, Context completes the same exact target without the stale caller signal and then replays newer explicit layer intent. Dedicated Voice Context cancellation reports a stable cancelled result plus the current Context state; generic layer visibility additionally exposes manager phase, reason, successor, and lifecycle details. Once an exact voice visibility intent commits, a newer voice turn cannot relabel it as cancelled while Context settlement completes; pre-commit aborts remain cancellable and final lifecycle mismatches remain failures.

 ### Motion & Symbology Correctness (June 10, 2026)
 
-- **Flights (commercial + military)** render one poll interval behind real time (30s/15s) and interpolate between two known feed-stamped fixes (OpenSky `time_position`; adsb.lol `receipt − seen_pos`). The display latency is an intentional product decision — do not "fix" it away. The fleet dead-reckons at ~12Hz (1m² write gating); a contact already hidden behind the horizon whose last position still is re-reckons on a staggered one-in-13-ticks rotation (about once a second) instead, so the worldwide feed's ~13k contacts no longer cost a full pass when well under 1% are on screen. Anything that position puts in view, and any contact with a fleet model, takes the full pass immediately, and hidden-inclusive proximity queries read positions at most about a second old; aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum. A nominally successful worldwide OpenSky response whose own snapshot epoch is more than two minutes old prefers the existing 250-nm viewport-scoped adsb.lol fallback and labels the source/coverage accordingly when that upstream is available.

+- **Flights (commercial + military)** render one poll interval behind real time (30s/15s) and interpolate between two known feed-stamped fixes (OpenSky `time_position`; adsb.lol `receipt − seen_pos`). The display latency is an intentional product decision — do not "fix" it away. The whole fleet dead-reckons at ~12Hz (1m² write gating); aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight.

 - **World-space headings at every angle** (`src/data/iconOrientation.js`): aircraft/vessel icon rotation uses the camera right/up basis per tick (alignedAxis always ZERO), which is exact at screen center and for orthographic/nadir views and remains stable through >180° tracked orbits. Perspective rays vary across the viewport, so off-center contacts at oblique pitch can diverge from an exact finite-difference window projection; a regression test pins that known regime, and field evidence decides whether to adopt exact projection with the basis method as fallback. Fleet rotations refresh on camera-pose change; tracked entities per frame. Billboards are horizon-culled via a shared EllipsoidalOccluder.
 - **Military/OpenSky reconciliation** (`src/data/militaryRegistry.js`): known-military ICAOs render amber in the flights layer (60s self-poll of the cached mil endpoint when the military layer is off) and are suppressed there while the military layer renders them.
-- **Satellites**: core catalog from CelesTrak's stations, visual, GPS, GLONASS, Galileo, GEO, resource, weather, planet, SAR and science groups, tracking lands ~726km out via `viewFrom` (tracked entity owns a point graphic so the tracking camera engages), rings realign via primitive modelMatrix (no per-second rebuild flicker), optional `setParams({catalog:'dense'})` Starlink mode.
-- **Satellite classes** (`src/layers/satellites/classes.js`): every satellite is filed under one of six classes, each with its own point colour, legend swatch and toggle: STATIONS (warm white), IMAGING (cyan), TELECOM (violet; communications and navigation, so GPS, GLONASS, Galileo and BeiDou read as one family), STARLINK (dim slate), PROBES (muted blue-gray) and DEBRIS (receding brown-gray). That module is the single source of truth for class, label and colour, so the dot, the card and the legend swatch cannot disagree. Two deliberate palette rules: no class may sit in the 40–48° amber band, which is the app-wide known-military convention; and STARLINK stays far below PROBES in Rec.601 luminance so the dense shell stays separable when NVG/FLIR collapse the scene to one channel. The ISS keeps its long-standing red hero dot rather than the STATIONS colour — it carries a permanent name label and its card still reads `STATIONS · ISS`; it is a station whichever group ingested it, so a stations-feed outage cannot refile it. `src/data/satelliteClass.js` keeps the group-based labels beneath the classes: the constellation subtype and a group's own label for a satellite with no class.
-- Class is also a **text field**, not just a color: `TELECOM · GPS` / `STARLINK` / `STATIONS · ISS` leads the tracked card's detail block and replaces the raw CelesTrak tag on the detection-overlay label. Because that canvas composites above the post-FX chain, the class stays readable in NVG/FLIR after the in-scene dot colors are flattened.
-- The satellites row in DATA LAYERS carries per-layer sub-controls (`DataLayerManager._syncRowControls`, the first consumer of the optional `getRowControls()` layer hook): one chip per class (the STARLINK chip exposes the existing `catalog` param), a swatch legend with live per-class counts, and an info line while SATCAT is stale or unavailable (`Classes may lag: SATCAT is a cached copy` / `Classes may lag: SATCAT unavailable`). Default is the sparse core catalog. The chips are stateless — each declares the params to apply and the manager owns the write — so the Space Missions capture/restore path over the same param stays authoritative. Controls stay hidden while the layer is off. An explicit CORE or DENSE choice participates in versioned local and share-link state; temporary Space Missions overrides do not.
-- **Class toggles** (`src/layers/satellites/classes.js`): the layer row carries one chip per class — STATIONS, IMAGING, TELECOM (communications and navigation), PROBES (science, technology development and demonstration, unknown purpose) and DEBRIS (rocket bodies, fragments, unknown objects launched before last year and dead payloads) on by default, so the layer shows what it did before classes; STARLINK off, as DENSE was. Points of a hidden class stay built and are only hidden, so a toggle needs no reload; hidden classes are left out of the detection overlay, the voice/framing position lists and analyst answers (the tracked satellite still answers), and the legend keys only the classes on screen. The class comes, strongest evidence first, from CelesTrak SATCAT (object type and operational status, fetched per group through `/api/celestrak-satcat/<group>`, cached a day by the proxy; the layer keeps a current read six hours rather than asking on every five-minute update), the bundled UCS Satellite Database pack (UCS-Satellite-Database 5-1-2023: operator, owner country and purpose; `src/data/local_data/ucs_satellites/`), name patterns for satellites launched after May 2023, and finally the CelesTrak groups the TLE came in (a mission group such as `weather` before the orbit group `geo`; a UCS purpose of "Unknown" counts as none). Only crewed stations and the craft that visit them, by name, are STATIONS: the CubeSats CelesTrak's stations group also carries after their deployment from the ISS are classed like any other satellite. A payload whose SATCAT record gives no status, with no UCS record and no recognisable name, that launched 20 or more years ago (SATCAT's launch date, else the TLE designator's year) is presumed dead and filed as debris; without a SATCAT record (a failed read) nothing is presumed. To cover imaging launched after the UCS snapshot the core catalog also reads CelesTrak's `resource`, `weather`, `planet`, `sar` and `science` groups. Debris can be tracked but is never ridden: the orbital entry gate (`orbitEntryAllowed`) refuses it, so no ORBIT entry is offered and double-click does nothing for it. Retired stations and the shuttles have re-entered and have no orbit to show. An explicit class choice is kept in local and share-link state as the `classes` option, one letter per class shown (`sitpd`: stations, imaging, telecom, probes, debris; `0`: none; `src/data/satelliteClassMask.js`), and the layer takes those letters back through `setParams({classes})`; STARLINK maps to the existing `catalog: 'dense'` param instead.
-- The satellite Cockpit subject (`getCockpitSubject()`) also carries `satelliteClass`, `cosparId` (from SATCAT, else TLE line 1), `tle` (`{line1, line2, epochMs}`), `owner` (`{countryCode, label}`: ISO 3166-1 alpha-2 for a single country, `null` code for organisations such as ESA, EUMETSAT or Intelsat and for joint owners) and `operator` (UCS; SpaceX for Starlink). UCS names the operator's country and wins over the SATCAT owner code; CelesTrak's CIS (former USSR) is filed under Russia.
-- **The STARLINK chip (formerly DENSE) reports the dense LOAD, not the catalog param.** The param flips synchronously while the Starlink shell takes seconds to arrive over a chunked load, and CelesTrak 502s that feed regularly. So the chip reads `STARLINK ···` (busy, disabled) while loading, ACTIVE only once dense points are actually on screen, and `STARLINK ✕` with the reason on hover when the load fails — a failure also reverts `catalog` to `core`, drops any partial chunk, and leaves the chip clickable to retry. A load is judged by points added, not by HTTP status: a 200 carrying an empty body, a passed-through HTML error page, or only TLEs the core catalog already owns fails with the same revert semantics as a 502. Any explicit request for `core` clears a latched error even when the mode does not change, so a Space Missions restore of an already-core snapshot never leaves the user with a failure they did not cause. Because the load settles asynchronously, the layer pushes a re-render through the optional `setRowControlsListener()` hook; nothing else would repaint that row before the 5-minute catalog refresh, so the count and legend would otherwise sit stale.
+- **Satellites**: 838-sat core catalog (stations/visual/GPS/GLONASS/Galileo/GEO), tracking lands ~726km out via `viewFrom` (tracked entity owns a point graphic so the tracking camera engages), rings realign via primitive modelMatrix (no per-second rebuild flicker), optional `setParams({catalog:'dense'})` Starlink mode.
+- **Satellite classes** (`src/data/satelliteClass.js`): every satellite is classified from the CelesTrak group it was ingested with — no extra fetch and no heuristics — into STATION (warm white), NAV (cyan; GPS/GLONASS/Galileo deliberately share one color so the GNSS family reads as one thing), GEO (violet), VISUAL (muted blue-gray catch-all), and COMMS (dim slate, dense Starlink shell only). That module is the single source of truth for class, label, and color, so the dot, the card, and the legend swatch cannot disagree. Two deliberate palette rules: no class may sit in the 40–48° amber band, which is the app-wide known-military convention; and COMMS stays far below VISUAL in Rec.601 luminance so the dense shell stays separable when NVG/FLIR collapse the scene to one channel. The ISS keeps its long-standing red hero dot rather than the STATION color — it carries a permanent name label and its card still reads `STATION · ISS`. `satelliteClassOf` is the single owner of that ISS rule, so the card label and the legend tally can never disagree: during a stations-feed outage the ISS is ingested as `visual`, and both surfaces still file it under STATION.
+- Class is also a **text field**, not just a color: `NAV · GPS` / `GEO` / `COMMS · STARLINK` / `STATION · ISS` leads the tracked card's detail block and replaces the raw CelesTrak tag on the detection-overlay label.

The chip is stateless — it declares the params to apply and the manager owns the write — so the Space Missions capture/restore path over the same param stays authoritative.

 - **A dependency owner takes the row with it.** Space Missions borrows this layer for TLE lookup with `showPoints:false`; while points are hidden the layer returns empty row controls, so the legend never describes an empty sky and the chip cannot accept a write that the owner's restore would silently revert.
 - The detection-overlay record cache (`_detectionObjects`) is cleared with the catalog on every rebuild: it stamps id/class at creation only, and a rebuild can re-tag a satellite when a partial CelesTrak outage changes which group wins dedupe.
 - **Catalog numbers above 99999** can be written in a TLE as Alpha-5: a letter A–Z, skipping I and O, for the first two digits, so `A0000` is 100000 and `Z9999` is 339999. CelesTrak's TLE feed carries no satellite above 99999 (that needs the OMM feed, #1191), so this is compatibility with Alpha-5 TLEs. `src/sources/tle.js` decodes the field through one shared helper: `noradIdFromSatnum()` for the satellites layer, which keys and deduplicates its catalog by that number, and `tleCatalogNumber()` for the satellite tools. Plain digits read as before (`noradIdFromSatnum()` accepts any length, as an OMM satrec carries the number unpadded); a malformed field — a sign, decimal point, hex, exponent, embedded space, stray or lowercase letter, or blank — is rejected rather than partly read, as `NaN` in the layer and `null` in the tools.

 - UTILITIES ▸ **Draw** turns the globe into a whiteboard drawn by hand. Pick a shape (icon buttons for Area, Line and Pin) and a colour swatch for the next shape, click the vertices on the real world, and finish. **Keyboard contract, live only while Draw is on and never while you are typing in another field:** Enter finishes the shape (as does a double-click, and the two cannot both submit it — the session is replaced before the annotate call is awaited); Backspace removes the last vertex; Esc cancels the shape in progress, and a second Esc — Esc on an empty session — leaves draw mode. **Clear** wipes the board (the shape in progress and every placed mark), so removing marks does not require the console or the microphone.
 - **Drawn shapes are listed under Draw like Import's files** (`src/ui/views/panels/DrawMarkList.vue`, rows worded by `presentDrawMarks` in `src/annotations/drawMarks.js`): one row per hand-drawn mark (`manual: true`; voice marks are not listed) with its colour swatch, its name, and show/hide, fly-to and remove. The draw tool publishes the rows with the rest of its controls and answers the row actions (`renameDrawMark`, `recolorDrawMark`, `toggleDrawMark`, `flyToDrawMark`, `removeDrawMark`) through the display store; it republishes on the engine's `onChange`, so a voice clear or an expiry updates the list. Rows are keyed and updated in place: a board change never takes a name being typed (the field keeps its draft while focused) or the button under a click. The name is saved on Enter or on leaving the field, once; Esc restores it, before anything else and with the row's colours open too. Both keep focus in the field, so neither drops it to the page or leaves Draw. The swatch opens the five colours right after it (shown at the end of the row), with the current colour focused; the arrows, Home and End try another, and a click or Esc closes them and returns focus to the swatch. Both colour groups (the next shape's and a row's) are one `DrawSwatches` radio group with a single tab stop, coloured from `DRAW_COLOR_CSS`; on touch screens each dot answers a 24 px target. An unnamed shape shows its kind, and an unnamed line its length; a renamed line keeps its length (`Ridge walk — 950 m`). **Hidden** keeps a mark on the board at alpha 0, and the world renderer takes every one of its entities out (`show = false`), so no material that keeps its own colour (the line's flowing stroke) still paints it; the screen renderer does not project a hidden callout, so it cannot push a visible label aside; `fly_route` skips a hidden route; and with every mark hidden the annotations render hold is released. **Fly to** is an immediate navigation (`runImmediateNavigation('drawing', …)`), like Import's: Cockpit refuses it and a running orbit, follow or track lets go first. A line is framed by its whole path, across the antimeridian too.
-- Runtime entry: `createApplicationTools` (`src/app/tools.js`, behind the `src/standalone/tools.js` shim) calls `initDrawTool({ viewer, annotations, navigation, publish, connect, markActions })` after `initAnnotations` and defers its `destroy()`, so disposing the shell returns every DOM listener, the Cesium handler, the preview data source, the borrowed click actions and the `window.__gevDrawTool` handle. Its controls are Vue views in the UTILITIES panel (`DrawControls.vue`, `DrawMarkList.vue`) that render what the tool publishes to the display store and call its actions. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `marks`, `setColor`, `diagnostics`) is the no-mouse test seam.
-- **One shape, handed back.** `createApplicationTools` also returns `drawShape({ shape, signal })` (`drawTool.drawShape`): it opens draw mode for one `area` or `line` and resolves with its geometry, a closed `[lon, lat]` `Polygon` or a `LineString`, without placing a mark; the shape chosen before comes back and draw mode ends. While it is open the controls cannot change the shape, and one across the antimeridian is refused as a row's actions refuse it ("That shape could not be placed.") and drawn again. It resolves `null` when the drawing is cancelled (the second Escape), draw mode is left, `signal` aborts, another request replaces it, the pointer is held elsewhere, the tool is destroyed, or the page has no Draw controls. It returns `pointerFree` (`data/inputOwnership.js` `isPointerFree`) too, so an application's own click handlers yield to the tool holding the pointer, as the layers' do.
-- **Row actions are an application's own.** `createApplicationTools({ drawMarkActions })` hands `initDrawTool` buttons for drawn areas' and lines' rows; the standalone shell passes none, so the open-source build shows no new button and makes no new request. Each action (`drawMarkActions` in `src/annotations/drawMarks.js`) is `{ id, icon, label(name), shapes: ['area', 'line'], accepts?(geometry, shape), run({ id, shape, name, title, geometry }) }`: the icon a Material Symbols name, the label worded by the application, `name` the person's own and `title` the row's (the name, else `Area` or `Line · 950 m`), the geometry `drawMarkGeometry`'s `[lon, lat]` `Polygon` (closed; a `MultiPolygon` for an area handle with several parts) or `LineString`, longitudes wrapped into [-180, 180]. A pin, and a shape that crosses the antimeridian or has a part that cannot be given whole, has no geometry and is offered nothing. Malformed actions and repeated ids are dropped once, at construction. What `run` returns or resolves to is a note under the row (`role=status`; past 200 characters it is cut at a word with an ellipsis); the row is busy (`aria-disabled`, no second press) until it settles, a rejection or a throw clears the note and is logged (so an action words its own refusals and resolves with them), and a shape's note goes with the shape, so a late answer never lands on a removed one.

 - Contract: a finished shape is submitted through the SAME `annotationEngine.annotate()` the voice agent uses, with geometry supplied and `manual: true` (`type: area` + `ring`, `type: route` + `path`, `type: pin` + coordinates). `resolveSpec` short-circuits manual specs (`resolveManualSpec`) so no geocoder, Places or Overpass call is made. A drawn area is a real (not synthesized) outline and drapes solid; a drawn line is a `route` with `mode: 'manual'`, labelled with its length and never a travel time; a pin is a point. Drawn marks therefore render with the whiteboard look, persist, appear in `.list()`, and clear with `clear_annotations` / `.clear()`. A drawn shape is never merged with another as a duplicate: every one is drawn on purpose, and every one is unnamed until its row names it, so two pins dropped close together are two pins.
 - **A vertex is a lon/lat, and the mark is DRAPED.** Clicks are picked through `pickWorldFromScreen` — one of two scene helpers the annotation resolver factory (`src/annotations/resolver.js`) exposes alongside `sampleGroundHeight`, so the app has ONE depth-aware pick cascade rather than a second written beside it — which returns the height the pick landed on as well as the coordinate, so the live preview hangs on the roof or hillside under the pointer instead of sinking to sea level. The world renderer draws areas and routes with `clampToGround`, so the height is dropped at finish in one place (`finishSpec`) rather than being carried downstream and discarded silently: what you get is the outline you drew, lying on the surface beneath it.
 - **Draped marks classify onto `ClassificationType.BOTH`** — terrain AND 3D tiles — not onto 3D tiles alone. With only `CESIUM_3D_TILE`, every area fill, area outline, route and arrow rendered to nothing on a keyless boot, where Cesium's own globe carries Esri/OSM imagery and there are no tiles to classify against; the labels appeared and the geometry did not. That hit spoken annotations exactly as hard as hand-drawn ones. `scripts/qa-draw-tool.mjs` counts the mark's own colour in the rendered frame before and after a shape is finished, on a keyed AND a keyless server, so "the board says there is a mark" can no longer pass for "the mark is on screen".

Turning off the ridden aircraft's layer ends the view (the layer clears its tracking). When an air feed the surrounding picture uses is off, the Cockpit says so instead of blocking: Live Signals leads with `MILITARY FEED OFF · PARTIAL PICTURE` or `FLIGHTS FEED OFF · PARTIAL PICTURE`, and the Contact card shows that line in place of its inputs status, so a partial picture is never presented as complete. `control_cockpit` refuses entry with `entryBlockedReason` `contacts-starting` (a Context change in flight), `subject-layer-off` (the aircraft's layer, or with none tracked any aircraft layer, is off) or `no-tracked-aircraft`.

Contacts outside the selected band use small rotation-free cyan-white pips for civilian aircraft and amber pips for military. The pilot's own airframe is not drawn in first person, and exiting clears the Cockpit band and restores normal map silhouettes/models. The normal left accordion remains available for Layers and Authoring and keeps the same 26vh HUD-aligned anchor used in map mode, independent of whether the bottom-left Contact card is expanded or collapsed; the right-rail CCTV and Context chooser are hidden to avoid duplicating or overlapping the cockpit presentation. When the intelligence HUD is enabled, its classification, scene summary, collection/orbit metadata, coordinates, and imaging-status text remain visible as reduced peripheral cockpit telemetry; the optical center and flight instruments stay clear, and turning the HUD off still hides it. Ground speed, exact heading, and rendered altitude form one compact lower-center instrument cluster, keeping the horizon and peripheral view open. A second live altitude tape hugs the inside-right visor rim: its rail and nine moving ticks are derived from the same responsive keyhole radius, remain 20 px inside the circular edge even on wide displays, fade deeply at both vertical ends, and move continuously behind a fixed current-altitude pointer; its interval tightens automatically near the surface and it is suppressed on narrow screens. Cockpit mode also has a weather-backed transparent volumetric-cloud pass derived from the supplied FBM/domain-warped R&D shader. It renders at no more than 520×320, uses 24 ray steps/three FBM octaves at 12 FPS, is clipped to the visor, fails clear when Open-Meteo is unavailable, and stops its animation completely on cockpit exit. It does not restore the prior CPU weather canvases, precipitation, scene fog, or any map-mode effect.

+  it settles. Turning off the layer the view rides ends it. Riding an aircraft
+  while Contacts is on adopts its layer as the user's own, as a direct selection
+  does (`adoptLayerVisibility`), so Contacts ending, by its own switch or one of
+  its layers going off, restores the pre-Contacts layers but keeps the ridden
+  one and the view; Live Signals then drops the rows Contacts built and shows
+  `CONTEXT STANDBY`. The visible Cockpit actions, the `C` shortcut and voice use
+  the same gate; voice entry still opens Contacts first, as its layer-targeted
+  entry navigates through Contacts.
+- **Aircraft cockpit view:** selecting a commercial or military aircraft reveals a `COCKPIT` action (`C`) once that aircraft's own layer is on; Contacts is not required. The action shows in Contacts (`#cockpit-entry`) and under the Intel HUD's bottom-right readout (`#cockpit-entry-readout`, with the HUD on, in its Tactical and Cyber layouts), so entry needs no Contacts panel. Turning off the ridden aircraft's layer ends the view (the layer clears its tracking). When an air feed the surrounding picture uses is off, the Cockpit says so instead of blocking: Live Signals leads with `MILITARY FEED OFF · PARTIAL PICTURE` or `FLIGHTS FEED OFF · PARTIAL PICTURE`, and the Contact card shows that line in place of its inputs status, so a partial picture is never presented as complete. `control_cockpit` refuses entry with `entryBlockedReason` `contacts-starting` (a Context change in flight), `subject-layer-off` (the aircraft's layer, or with none tracked any aircraft layer, is off) or `no-tracked-aircraft`. Cockpit mode temporarily releases Cesium's orbit-follow transform and drives a first-person camera from the tracked aircraft's existing smoothed display position and course. Its concave helmet-visor HUD shows callsign, UTC time, coordinates, curved roll/pitch guides, and a seven-division heading tape. Ambient commercial and military AIR contacts use a Cockpit near/far band selected by the shared Display 3D mode: Proximity admits at 150 km and retains to 185 km; All admits at 400 km and retains to 450 km.

 - **Cockpit left-panel clearance:** the Cockpit Contact card and peripheral HUD participate in the adaptive left accordion's live obstacle measurements, including live viewport-height changes. Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
-- **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls are the way in and out; Cockpit claims no `C` shortcut, so `C` keeps toggling CCTV, also inside a first-person view. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, and `NOIR`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.

 - Cockpit wind-direction labels wrap after rounding to whole degrees, so a direction of 359.5° displays as `N · 0°` rather than `N · 360°`.
 - The transit, ALPR, vessel, CCTV, Local ADS-B, flight and military context, awareness, Cockpit and Street Level heading readouts round through `roundHeadingDegrees` in `src/data/headingDegrees.js` (whole degrees 0–359, `null` when not finite, so each caller keeps its own placeholder); `normalizeHeading` lives there too and `cockpitMath.js` re-exports it. The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.
 - **Cockpit missing observations:** missing local weather observations remain unknown rather than being converted to zero or clear skies, in the briefing and in the cloud effects; a missing temperature drops the whole local weather record, including its wind and condition.

-## Québec CCTV integration
-
-The regular CCTV source loader reads `public/quebec-cameras.json` by default
-when `CCTV_QUEBEC_ENABLED` is not `0`. The pack contains 1,120 records: 680
-MTQ highway cameras, 426 Montréal OSM camera locations, and 14 scenic webcams.
-The default catalog limit is 7,350: it reserves all 1,120 Québec locations and
-2,230 World image feeds, and keeps 4,000 slots for the existing round-robin
-camera packs. Reservations only use capacity above those 4,000 slots: a lower
-explicit `CCTV_MAX_SOURCES` thins every pack round-robin, Québec and World
-included, instead of taking the shared slots.
-
-The Québec 511 video is opt-in (`CCTV_QUEBEC_VIDEO_ENABLED=1`) because Québec
-511's terms for embedding its clips on another site are unconfirmed; the camera
-locations themselves are CC BY 4.0. With the flag unset, MTQ cameras show
-their location, credit and a link to the Québec 511 viewer page. With it set,
-selecting an MTQ camera opens a floating panel with a Play button and a notice
-that Québec 511 sees the viewer's IP address; the browser contacts Québec 511
-only after Play, never on selection alone (layer enable, auto-hop, a scene or
-voice), and a different camera starts unplayed. After Play, the panel plays
-the official MP4 in a native browser player and requests a second video for the
-paused map preview. The official feed is a five-second clip refreshed by
-Québec 511 every 2–4 minutes, not continuous live video; the browser player
-reloads every two minutes while the tab is visible. The
-map preview is a DOM overlay attached to the camera's coordinates and scales
-down with camera distance. Neither video is read into a canvas or Cesium texture:
-Québec 511 does not grant localhost pixel access, and its MP4 is not available
-to the app's server proxy. Montréal and scenic entries are regular CCTV camera
-locations with per-camera source-page links, but no direct frame URLs; those
-show a location label and open the official/operator page. MTQ positions carry
-CC BY 4.0 attribution, Montréal positions are attributed to OpenStreetMap
-contributors under ODbL, and scenic rows retain their position accuracy and
-provenance. Québec cameras load through the normal CCTV layer.

-## City of Ottawa CCTV source pack
-
-The CCTV catalog can add City of Ottawa traffic cameras, including the MTO
-cameras the city carries. Camera images come from the city's Traffic Camera
-Images API (`traffic.ottawa.ca/opendata/camera`), which needs a certificate
-from the city's registration form and lets one certificate and user id fetch a
-camera at most once a minute. Without `OTTAWA_CAMERA_CERTIFICATE` the pack is
-skipped with no request and one log line. The camera list is the documented
-keyless `traffic.ottawa.ca/map/service/camera` JSON. Catalog URLs carry no
-key: the frame proxy adds the certificate and the fixed user id `gev` at fetch
-time, only for a numeric camera number inside the pinned `/opendata/` path,
-and serves each camera from one shared server-side frame per minute. Inside
-that minute a camera with no cached frame gets the placeholder, never the
-Street View fallback. The feed publishes no bearing, so headings use the
-id-hash fallback at low confidence. `CCTV_OTTAWA_MAX_SOURCES` caps the pack
-(default 250, nearest downtown) and `CCTV_OTTAWA_ENABLED=0` turns it off.
-
-## World camera image feeds
-
-The default `world-cameras` pack reads only the checked-in, curated
-`config/cctv_sources.world-image-cameras.json` file. It adds 1,176 Oregon
-TripCheck and 1,054 MLIT river cameras. Duplicate feeds are excluded because
-DriveBC, Ottawa, Québec and Iceland (Vegagerðin) already have app packs. NZTA's
-249 rows are excluded because they were collected from a Journey Planner web
-cache whose current terms prohibit automated scraping; an authorized API feed
-or permission is required before adding them. The wider discovery export is
-not shipped with the app.
-
-The app validates and pins each still-image URL to its provider directory
-before the server proxy uses it. Oregon frames refresh no faster
-than every five minutes; MLIT river frames refresh every ten minutes to reduce
-requests. Images are not persisted; the proxy reuses frames in a bounded 32 MB
-in-memory cache until their provider cadence. Set
-`CCTV_WORLD_CAMERAS_ENABLED=0` to disable the pack.
-
-Only the curated image-backed rows are bundled. Camera images are fetched from
-their registered providers at request time and are not included in this data
-file. The additive `/api/cctv/sources` metadata includes provider source links,
-browser-only media links, refresh cadence, and location provenance where
-available. When MLIT serves its recognized adjustment image, `/api/cctv/frame`
-returns a God’s Eye maintenance card and `/api/cctv/health` reports the camera
-as degraded with the provider-adjustment reason.
