 # Changelog
 
+- The tracked-aircraft descriptor now publishes `verticalRateMps`, on both the
+  civil and military layers, so a consumer reading `getTrackedInfo()` no longer
+  has to reach past it into the raw poll record for climb/descent. Reported,
+  never derived: an aircraft that has not transmitted a rate reads as `null`
+  rather than a level-flight `0`.
+
+- Add nine Ontario transit feeds: TTC, MiWay, Hamilton HSR, Durham Region,
+  YRT/Viva, Guelph, Burlington, Barrie and Kingston, each carrying its own
+  licence quote and attribution. A feed can now name its own modes, so Toronto's
+  trams read "Streetcar" while Helsinki's stay "Tram", and a feed whose route ids
+  are internal keys can translate them to the number a rider would say. TTC
+  vehicles take their mode from the fleet number first, so replacement buses on
+  streetcar routes read as buses and out-of-service streetcars stay streetcars.
+
+- CCTV cameras with identified hardware show the model's datasheet specs. When a
+  source names a camera model found in the vendored CCTV Camera Database records
+  (CC0), the HUD meta line adds its resolution, night vision and PTZ capability.
+  A fixed single-lens model's horizontal FOV fills in when the source states no
+  FOV and the pose is not curated (`FOV n° (DATASHEET)`); a PTZ or varifocal
+  range is what the lens can do, not its current zoom, so those cameras keep the
+  estimate and show `SPEC FOV min–max° (CAPABILITY)` beside it (bassem chagra,
+  #452).
+
+- Ship a web app manifest and raster home-screen icons, so adding the app to a
+  phone home screen or installing it on desktop uses the God's Eye View mark
+  instead of a blank tile. The icons are generated from `public/logo.svg` by
+  `node scripts/generate-icons.mjs` and committed, so a plain `vite build` needs
+  no image toolchain. The existing SVG favicon still serves the browser tab.
+  Manifest paths are relative to the manifest, so a build served under a path
+  prefix installs and launches inside that prefix.
+
+- Cyclone advisories no longer go dark while NHC publishes an advisory ahead
+  of its nominal time: advisory and position times up to 90 minutes ahead of
+  the server clock are accepted (previously 5 minutes), so the whole feed is
+  not rejected for about half an hour each advisory cycle.
+
+- Flights age out vanished aircraft again. OpenSky's routine position-less rows
+  no longer mark every snapshot partial, which had kept vanished and landed
+  aircraft at full opacity for up to five minutes; those rows retain only their
+  own aircraft, and a likely-landed one still leaves on the landed limit.
+
+- Add WSDOT highway cameras (Washington State) as a keyless CCTV source pack:
+  WSDOT's official Travel Center camera layer, with frames registered only on
+  WSDOT's own image host (partner-hosted cameras such as Oregon DOT and City of
+  Seattle are skipped). Cameras with a single cardinal `CompassDirection` get
+  a high-confidence heading; `B` (both directions), `O`, and unset directions
+  use the shared id-hash fallback at low confidence. By default the 250
+  cameras nearest Seattle and Spokane load; `CCTV_WSDOT_MAX_SOURCES` sets the
+  cap (8–1,200) and `CCTV_WSDOT_ENABLED=0` turns the pack off (bassem chagra,
+  #644).
+
+- Refuse still-image cameras on the CCTV media relay. `/api/cctv/media` is the
+  live-feed route, but it also relayed any registered still camera through an
+  ordinary fetch that followed redirects to any host, passed through whatever
+  content type came back and had no cap on the body, bypassing every protection
+  `/api/cctv/frame` applies to the same URL. Only HLS, MP4, WebM and MJPEG
+  feeds are relayed now; a still camera, or an unknown id, gets a JSON 404
+  without an upstream request and is served only through `/api/cctv/frame`.
+  The client already loaded stills through `/frame`, so nothing it requests
+  changes.
+
+- Add Lithuania's public Via Lietuva / Eismoinfo road cameras to CCTV, with published coordinates, on-demand snapshots, attribution and bounded catalog requests. No API key is required. The pack is opt-in (`CCTV_LITHUANIA_ENABLED=1`) because its camera endpoints are the eismoinfo.lt website backend, not a service listed in Via Lietuva's open-data statement, so the licence for the photos is unconfirmed.
+
+- Add King County road cameras (Washington State) as a keyless CCTV source
+  pack: one public King County DOT ArcGIS layer, fetched with an explicit field
+  list so its staff-name columns are never requested, and frames pinned to the
+  county's own image host and upgraded to HTTPS. WSDOT-owned rows are skipped,
+  and city-owned cameras the county hosts credit their owner. The layer
+  publishes no facing, so headings use the shared id-hash fallback at low
+  confidence. It does publish each camera's hardware, which is served on
+  `/api/cctv/sources` as `model` and `manufacturer`. `CCTV_KINGCOUNTY_MAX_SOURCES`
+  sets the cap and `CCTV_KINGCOUNTY_ENABLED=0` turns the pack off
+  (bassem chagra, #645).
+
+- Add City of Toronto RESCU traffic cameras as a keyless CCTV source pack: the
+  ~336 municipal cameras the Ontario 511 pack does not carry — downtown
+  arterials plus the Gardiner, DVP, Allen and Lake Shore. The list is the
+  City's own open data feed; frames are built from the documented
+  `loc####.jpg` convention and a digits-only camera number, so the frame proxy
+  is pinned to the portal origin by construction. The dataset publishes no
+  camera facing — its `D1`-`D4` fields describe static 2016 comparison images,
+  not the live pan-tilt-zoom frame — so headings use the shared id-hash
+  fallback at low confidence and are corrected with the calibration gizmo.
+  Carries the required Open Government Licence – Toronto attribution. Disable
+  with `CCTV_TORONTO_ENABLED=0`.
+
+- Stop one retired bikeshare feed from reporting the whole layer as failed.
+  City feeds are fetched independently, but failure was recorded in a single
+  flag that only a successful *activation* cleared — and an already-loaded city
+  never activates again. A dead feed re-entering camera range therefore latched
+  LOAD FAILED permanently over a map still drawing every other city's stations.
+  Failure is now tracked per city: a city that fails beside others still
+  drawing marks the layer DEGRADED, polls that all fail over previously drawn
+  points read STALE without advancing freshness, and LOAD FAILED is reported
+  only when nothing is left to draw. A city that recovers clears its own
+  failure, a failure is dropped once its city leaves range or the camera rises
+  above the activation altitude, and late results from superseded requests are
+  ignored.
+
+  Repointed the three feeds whose operators had moved: Reddy Bikeshare (Buffalo)
+  to Social Bicycles, Tugo (Tucson) and Trinity Metro (Fort Worth) to PBSC.
+  Dropped CoGo (Columbus) and Broward B-cycle (Fort Lauderdale), whose systems
+  have wound down — CoGo's feed reports no stations and last moved a bike in
+  March 2025. The three repointed feeds were verified live.
+
+- Add seven Brazilian Bike Itaú (Tembici) cities to the GBFS bikeshare registry:
+  São Paulo, Rio de Janeiro, Salvador, Recife, Porto Alegre, Brasília and
+  Curitiba (about 1,000 stations in total). These are the layer's first stations
+  in South America.
+
+- Add Bike Share Toronto (1,069 stations) to the bikeshare registry. The system
+  publishes the same PBSC GBFS v2 feeds as the Austin, Honolulu and Chattanooga
+  entries, so it needs no new plumbing; a registry test now holds every city's
+  feed URLs against the proxy host and path allowlists, so a city the proxy
+  would refuse fails the suite instead of rendering an empty layer.
+
+- GBFS v3 station names use English translations when available, then the first
+  usable translation or short name. Empty or malformed names no longer appear as
+  `[object Object]` or interrupt station loading; legacy string names remain
+  supported in the globe and bike-share tools. Thanks to

 ## [Unreleased]
 
+- Add a keyless Air quality layer to the Weather group, with Environment and
+  Climate Change Canada's AQHI as the first registered provider. Readings carry
+  `{ provider, scale, value, band }` so another network can be added without
+  inventing a shared numeric meaning across indices that do not share one; the
+  row and readout both state that coverage is Canada only. The WEATHER card
+  shows the band legend and the highest readings currently in view. AQHI is
+  reported as an integer from 1 with an open-ended "10+", so readings round to
+  that published form rather than the decimal precision the API returns.
+  Readings older than six hours are dropped, and the layer reports `stale`
+  through `getStats()` (also when every observation was dropped) so feed
+  provenance cannot describe an aged feed as live. Voice can switch it on and
+  query readings by value, band, station and observation time.
+
+- Bound six upstream body reads (FIRMS CSV, CelesTrak TLE groups, adsb.lol
+  `/v2/mil`, TomTom flow tiles, OpenSky `states/all` and adsbdb lookups) with
+  streaming size caps that cancel the body at the cap or the route's deadline;
+  the adsb.lol military poll gains a deadline of its own. An oversized OpenSky
+  snapshot is not retried, and an OpenSky 429 starts its cooldown before the
+  body is read.
+
+- Keep later satellites when a TLE catalog entry is missing an orbital line.
+  The parser skips the incomplete set and resumes at the next complete named
+  set, instead of losing the rest of the group (#906).
+
+- Satellite clouds keep Clouds only / Full as quick endpoints and add a continuous
+  cloud-filter slider: 0% is Full, 100% is the existing brightness key, and
+  intermediate values blend the keyed alpha. The slider commits on release to
+  avoid restaging imagery for every drag event. Filter percentages round-trip in
+  share links; legacy mode codes retain their old endpoint meanings. Background
+  panel refreshes preserve the pending drag value until release. Contributed by
+  [NotProniss](https://github.com/NotProniss) (#1084).
+
+- Street Level: Panoramax is the fourth provider, keyless. Light its chip
+  (orange; off by default, one provider at a time): from orbit dots show
+  where the federated commons has pictures, and below about 60 km its
+  sequences draw as lines from `api.panoramax.xyz` vector tiles. A click on a
+  line opens that sequence's picture nearest the click without moving the
+  camera, flat or 360°, with cones along the sequence around it and ‹ › /
+  ← → following the picture's own links. The 360° and since filters apply,
+  in the lines and in the lookup. The caption names each picture's author
+  and licence (CC BY-SA 4.0, Licence Ouverte 2.0…) and links to it in the
+  Panoramax viewer. HD originals load once, only when the viewer is wider
+  than the 2,048 px version (a panorama: expanded), and every download stops
+  when the photo changes; an image whose header declares more than 64 MP is
+  refused before it decodes. Share links carry it as
+  `0.m.0_0.r.google-0*kartaview-0*panoramax-1` (`0.m.0_0.r.panoramax-1` works
+  too). KartaView's photo viewer
+  is now shared (`photoViewer.js`, `panorama.js`); in it, for KartaView too,
+  Esc clears the selected drive before it collapses the panel. Lines are
+  simplified and drawn within a point budget (a tile's unsimplified lines
+  over Paris hung the tab), decoded in slices so the globe keeps moving,
+  and kept; the cones' tiles have their own connection, and the open
+  picture's tile draws its cones before its neighbours arrive.

 ### Notes on the live sources
 
+- **Air quality (ECCC AQHI).** Keyless. Read from the MSC GeoMet OGC API (`api.weather.gc.ca`): the `aqhi-stations` catalog plus `aqhi-observations-realtime`. **Coverage is Canada only** — ECCC is the single registered provider, and the layer row and readout card both say so. Roughly 134 stations across ECCC's five administrative zones (Atlantic, Quebec, Ontario, Prairies & North, Pacific & Yukon). AQHI publishes hourly, so readings poll every 20 minutes and the station catalog, which changes a few times a year, is refetched only every 12 hours. Observations are requested with `latest=true`; without it the collection returns the full history, roughly 2,000 rows nationally. Readings older than six hours are dropped rather than displayed as current.
+
+  Readings are stored as `{ provider, scale, value, band }` rather than a bare number, because air-quality indices are not interchangeable: AQHI runs 1-10+ on health risk, the US AQI runs 0-500 on concentration breakpoints, and Europe's EAQI is a five-step category. Naming the index a value belongs to is what lets another network be added later without inventing a shared numeric meaning that does not exist.
+
+  AQHI is reported by ECCC as an integer from 1 to 10 with an open-ended "10+" above that. The API returns the underlying decimal (1.08, 2.32); the layer rounds to the published form rather than displaying a precision the index does not claim.
+
+  **Quebec is thinly represented**, and that is upstream rather than a filter here: the province runs its own Info-Smog program, so only a handful of Quebec stations appear in ECCC's national feed. The reporting station count also varies hour to hour as stations report or fall silent.
+
+- **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.
+
 - **Google Maps Platform.** You supply your own API key and are bound by [Google's ToS](https://cloud.google.com/maps-platform/terms). Google Maps Content (tiles, geocodes, places) **may not be cached, stored, rehosted, or committed** — this app only ever uses it live, which is the compliant pattern. The "Google" attribution is displayed on the globe and must stay visible. Restrict your key (see [SECURITY.md](SECURITY.md)).
 - **OpenSky Network.** Its license is **non-commercial**, and operational use of the REST API in a live product can require a prior written agreement with OpenSky — even for non-profit/government use. If you deploy this commercially, contact OpenSky for your own terms. The flights layer is a toggle and runs anonymously by default.
 - **adsb.lol flight fallback.** When OpenSky is unavailable and no last-good OpenSky response exists, the server requests a cached, capped 250 nm adsb.lol point snapshot around the current camera subpoint. This is regional observed context, not worldwide completeness; provenance is exposed in the Flights stats/context row. Military ICAOs remain reconciled through the existing dedicated military registry rather than duplicated.

 - **Warendorf webcam.** The Stadt Warendorf Marktplatz webcam, registered from the curated `config/cctv_sources.warendorf.json` (the Kreis Warendorf registration-office cameras from the contributing PR are indoor waiting rooms and were left out); only the municipal image host is proxied, frames are fetched at request time and never stored or redistributed. Disable with `CCTV_WARENDORF_ENABLED=0`.
 - **Live Traffic NSW cameras.** The camera list is the keyless public `data.livetraffic.com/cameras/traffic-cam.json` feed (Transport for NSW open data, CC BY 4.0); frames are stills on `webcams.transport.nsw.gov.au`, and only that host is registered. That image host answers non-browser clients with an HTML placeholder, so the proxy identifies as a browser for that one host and as itself everywhere else. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_NSW_ENABLED=0`.
 - **Open Calgary traffic cameras.** Keyless. The camera list is the public Socrata dataset `k7p9-kppz` on `data.calgary.ca`; frames are stills on the city's own `trafficcam.calgary.ca` host, and only that host is registered. Most rows publish an `http://` frame URL and the host redirects those to HTTPS, so URLs are upgraded and pinned to that origin before registration. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `quadrant` field and the quadrant suffix on each camera name are Calgary's address grid, not a bearing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. The licence requires the attribution statement above. Disable with `CCTV_CALGARY_ENABLED=0`.
+- **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`.
+- **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.
 - **Statens vegvesen road cameras.** Keyless. The camera list is one GeoJSON request to the OGC API Features view of the official DATEX 3.1 CCTV site table (`ogckart-sn1.atlas.vegvesen.no/ogc/features/v1/collections/datex_3_1:CctvSimple/items`), so no DATEX account is needed; frames are stills on `kamera.atlas.vegvesen.no/api/images/<cameraId>`, and only that exact path per camera is registered. Cameras the feed reports as faulty are dropped. About 135 working cameras also publish live HLS (`kamera.vegvesen.no/public/<cameraId>/manifest.m3u8`, MPEG-TS); those play as live video through the bounded in-memory HLS relay, with the still as the snapshot fallback, and only that exact manifest path per camera is registered. `CCTV_VEGVESEN_VIDEO=0` keeps every camera on stills. `orientationDescription` names the place a camera faces, not a bearing, so it goes into the label and headings use the id-hash fallback at low confidence. By default every live camera loads (~850); `CCTV_VEGVESEN_MAX_SOURCES` (8–1000) lowers the cap, keeping the cameras nearest Oslo, Bergen, Stavanger, Trondheim, Kristiansand, Bodø and Tromsø and `CCTV_VEGVESEN_ENABLED=0` turns the pack off. Frames are fetched at request time and never stored or redistributed. The NLOD attribution is registered in the Data attribution popover.
 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `[email protected]` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
+- **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.

Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington and YRT publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.
 - **Radio Browser.** `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

 **macOS shortcut:** `./scripts/dev-fresh.sh` clears the Vite cache and pulls any

+### Path 3 — Docker
+
+No Node install needed; the container publishes the same dev server.
+
+```bash
+git clone https://github.com/bilawalsidhu/gods-eye-view.git
+cd gods-eye-view
+docker compose up
+```
+
+Open **`http://localhost:4173`** as above. Everything the app saves stays in the folder you cloned, so `docker compose down` never loses anything:
+
+- `.env` - your API keys, whether saved from Provider Settings or typed in by hand
+- `.gev-cache/` - downloaded map and satellite data, so later starts are faster
+- `.gev-logs/` - logs
+
+Back up that folder and you've backed up everything; delete `.env` to forget your keys. Source edits still hot-reload. The port is published to `127.0.0.1` only, so the default matches the native one.
+
+The local MCP server and ChatGPT OAuth voice are not available under Docker; use an OpenAI API key for voice.
+
+Publishing it wider is the [Sharing an instance](#-sharing-an-instance) opt-in, and it hands out **Provider Settings** too: the launcher trusts the container gateway as this machine, and a wider publish delivers everyone else from that same address. For an instance you mean to share, put the keys in `.env` by hand instead. [SECURITY.md](SECURITY.md) has the detail.
+
+When you widen the publish, also set `GEV_KEY_SETUP_TRUSTED_PEERS=none` so the launcher trusts no gateway address.

+Run it as the user who should own the files it writes. `id` shows the numbers; for yourself on Linux:
+
+```bash
+env UID=$(id -u) GID=$(id -g) docker compose up
+```
+
+On a NAS, clone onto the share you want the data on and use the share owner's ids:
+
+```bash
+cd /volume1/docker
+git clone https://github.com/bilawalsidhu/gods-eye-view.git
+cd gods-eye-view
+env UID=1026 GID=100 docker compose up -d
+```
+
+Keep the `env`: bash treats `UID` as read-only, so a plain `UID=1026` in front of a command is silently ignored. If the container can't write the checkout, it says so at start. Docker Desktop on macOS and Windows maps ownership for you.
+
+Behind a reverse proxy, put your keys in `.env` or pass them as environment variables - Provider Settings refuses proxied requests on purpose - and add the hostname you serve it on, for example `GEV_ALLOWED_HOSTS=globe.example.lan` (see [Sharing an instance](#-sharing-an-instance)).
+
+</details>
+
+<details>
+<summary>IPv6-only networks, rebuilding, and the test suites</summary>
+
+The launcher reads the IPv4 default gateway, so an IPv6-only Docker network
+finds none: it logs `No default gateway; Provider Settings stays loopback-only`
+and the panel refuses every save. Put your keys in `.env` by hand there, or name
+the gateway yourself with `GEV_KEY_SETUP_TRUSTED_PEERS` after reading
+[SECURITY.md](SECURITY.md).
+
+`node_modules` deliberately stays inside the image, so it survives in an
+anonymous volume across restarts: after a `git pull` that changes dependencies,
+recreate it with `docker compose down -v && docker compose up --build`. The
+image also skips Puppeteer's Chromium download, which keeps it small but leaves
+`npm run test:track` to the host — `npm run build` and `npm test` run fine in
+the container.

Photos KartaView has archived are skipped, and where all are archived the panel says so. For KartaView, **SINCE** goes by upload date, as KartaView's own map does (it can filter by nothing else), and the panel notes it under the slider; KartaView filters its lines on its own server, and a filtered area KartaView has not drawn before can take several seconds, and the unfiltered lines show meanwhile. On the **Google 3D** map (Google's terms keep Street View off other maps, where it does not appear), light **GOOGLE STREET VIEW** and click a street from below 3 km, or press **OPEN STREET VIEW** for the view centre, to open Google's panorama there; step along its arrows. Above the photo: **EXPAND**, **FIT / FILL** (Mapillary, and flat KartaView photos), and **FOLLOW** (the globe camera follows the photo's view; Google 3D map only). The caption links to the image on the provider's site, and the globe credits each provider that is on ("© Mapillary contributors, CC BY-SA 4.0", "Street View imagery © Google", "© KartaView contributors, CC BY-SA 4.0"). KartaView's own photo pages fail for signed-out visitors, so its link opens the full-size photo.

 - **Full Content-Security-Policy.** The dev and preview servers send a real CSP (`script-src 'self' 'unsafe-eval' blob:` plus the YouTube, Facebook and X scripts the Nepal event's embedded media loads and the Maps JavaScript API that Street View runs on, with a matching `frame-src` for their players and posts: no inline script and no other script origin; `blob:` covers the object URLs Cesium's bundled workers bootstrap through in the built app), alongside the existing `X-Frame-Options: DENY` and `frame-ancestors 'none'`. `'unsafe-eval'` stays because Knockout, bundled inside Cesium's widgets package, resolves the global object with `eval` at load time and the globe does not initialize without it; styles permit `'unsafe-inline'` and Google Fonts because Vite's dev client injects `<style>` elements.
 
 Allowing `maps.googleapis.com` in `script-src` also trusts its JSONP endpoints, which can bypass the script allowlist if an HTML-injection bug exists; this is an accepted limitation of loading the Maps JavaScript API, alongside the existing `'unsafe-eval'` allowance.

 - **Local-only by default.** `./scripts/dev-fresh.sh` (and the Vite config itself) bind to `localhost`, so only your machine can reach the server — and only local names are accepted (`allowedHosts` stays restricted, which also blunts DNS-rebinding tricks). Binding to all interfaces keeps that restriction: IP addresses and `localhost` work, and LAN hostnames must be listed in `GEV_ALLOWED_HOSTS` (for example `GEV_ALLOWED_HOSTS=globe.lan`); suffix and wildcard entries are ignored.
 - **LAN exposure is an explicit opt-in**: `HOST=0.0.0.0 ./scripts/dev-fresh.sh`. The launcher prints a prominent warning plus your LAN URL. Understand what opting in means: **every device on that network can drive the proxies and spend your OpenAI / Google / OpenSky / AISStream / TomTom / FIRMS quota** for as long as the server runs. Do this only on networks you trust.
 - **App-level throttles (on by default):** `GEV_RATELIMIT_OPENAI_PER_MIN` (default `30`) and `GEV_RATELIMIT_GOOGLE_PER_MIN` (default `120`) — the values the Pinokio build already ships — cap the cost-bearing endpoints per client IP per minute (over-limit requests receive a sanitized `429`). Both defaults sit well above what the app itself generates; set either to exactly `0` to run unthrottled. They are **per-IP, process-local, in-memory guards** — they reset on restart, a caller with several addresses gets a bucket per address, and they are **not billing caps**.
+- **Docker trusts one address, and only because the port is on loopback.**
+  Docker delivers the host's own browser to the container from the container
+  network's gateway, never from `127.0.0.1`, so a loopback-only Provider
+  Settings refuses the machine running it. `scripts/docker-start.mjs` therefore
+  sets `GEV_KEY_SETUP_TRUSTED_PEERS` to exactly that gateway address. The list
+  takes exact addresses only (no wildcards, prefixes or hostnames), is unset
+  under every other launcher, and relaxes none of the sharing, Host, Origin,
+  Content-Type or proxy-header checks. It is safe precisely because
+  `compose.yaml` publishes on `127.0.0.1`: **widen that mapping and every LAN
+  client arrives from the same gateway address, which hands them Provider
+  Settings too.** Treat publishing beyond loopback as the LAN opt-in above.
 - **Provider-side budgets are the real backstop.** For hard spend protection, configure limits where the money is: OpenAI platform usage limits, Google Cloud budget alerts + per-API quotas, and equivalent controls for any other keyed provider.

+the top of the file, so two pull requests in flight write into the same few lines
+and git has nothing to merge on.

+stops the run before anything is written and names the files.
+
+If `npm run changelog` fails part-way (a full disk, a killed process), run it
+again. The batch is staged in `changelog.d/.assembling/` and only lands when the
+assembled file replaces `CHANGELOG.md` in a single rename, so the rerun either
+finishes that batch or puts its fragments back first. It never adds an entry

+`src/annotations/drawTool.test.mjs` asserts against `CHANGELOG.md` — should
+assert against `docs/CURRENT-STATE.md` or `README.md` instead. A pull request

+### Interface localization (October 2026)
+
+Shipped locales: **en** (source and fallback), **es** and **ru**. The code lives in
+`src/i18n/`. How to mark UI text: [`docs/I18N.md`](./I18N.md); translator workflow:
+[`docs/TRANSLATORS.md`](./TRANSLATORS.md).
+
+- **Keys are the English text.** `t('Save keys')`, `tn(count, '{count} camera',
+  '{count} cameras')`, and `msg('Live Flights')` for text stored in data and
+  translated later. Markup opts in with `data-i18n` (element text) and
+  `data-i18n-title` / `-aria-label` / `-placeholder` (that attribute's English
+  value). English has no catalog; every other locale is
+  `src/i18n/locales/<code>.json`, and a missing entry falls back to English.
+- **Locale choice.** `?lang=` → stored choice (`gev:locale:v1`) →
+  `navigator.languages` → English. `?lang=` is not stored, and share links drop
+  it, so a recipient keeps their own language. The globe picker in the
+  bottom-right corner (`src/ui/localePicker.js`) stores the choice, drops
+  `?lang=` (keeps it only when storage is blocked) and reloads. It asks first
+  when the reload would lose work registered with `registerUnsavedWork`:
+  unsaved keys or CCTV calibration, Draw marks, imported map files, the open
+  cockpit, a voice session.
+- **Gate.** `npm run i18n` (and `src/i18n/catalog.test.mjs` under `npm test`)
+  extracts every message and fails on missing, empty, unused,
+  placeholder-mismatched, still-English (plural forms included) or
+  wrongly-shaped plural entries.
+- **Not translated by design:** layer ids, share-link and hash parameters, API
+  fields, voice tool schemas, provider names, feed data (callsigns, vessel and
+  station names) and attribution.
+- **Unmarked text.** The same check lists UI text that is not marked at all
+  (markup without `data-i18n*`, literals reaching the page without `t`/`tn`/`msg`)
+  and fails on it. Text kept on purpose says why: `translate="no"`,
+  `data-i18n-runtime`, or `// i18n-ignore: <reason>`. `src/tools/` is skipped:
+  it writes for AI clients, not the page.

+pages fail for signed-out visitors. The viewer itself is `photoViewer.js`,
+shared with Panoramax: each provider hands it a `PhotoSources` table (first
+and sharper flat and panorama URLs, and the caption fields).
+
+Panoramax (`providers/panoramax/`) is keyless and browser-side: the
+meta-catalogue `api.panoramax.xyz` (CORS open) federates every instance, and
+each picture is served by the instance holding it (OpenStreetMap France,
+IGN, MapComplete…; IGN's redirect to its OVH object storage). Its chip
+(orange, `#ff6f00`, Panoramax's own) starts off. Coverage comes from its
+vector tiles (`/api/map/{z}/{x}/{y}.mvt`, an hour's HTTP cache): sequence
+lines from z14 below 1.8 km above ground, z13 to 5 km, z12 to 12 km, z11
+to 30 km and z10 to 60 km, as Mapillary's (a dense z10 tile over Paris is
+~2.1 MB and 8,600 sequences, 750,000 points). `decode.js` simplifies each
+line (Douglas–Peucker to the segment, 4 units of a 4,096 tile: about a
+pixel where it is drawn, 6–10% of a GPS track's points), and the tiles in
+view draw their longest lines within 90,000 points (`maxPoints`,
+`keepOrder`), shared out once loading settles so a sparse tile keeps all
+it has and a dense one (a city centre) takes the rest; the selected
+sequence is always drawn. Every point becomes ~8 ground-line vertices:
+unsimplified, the lines hung the tab. Decoded tiles are kept while the
+provider is on (16, ten minutes, `tileCache.js`, shared with KartaView),
+and above
+60 km the `grid` layer's 0.1°
+density cells, binned to at most 96×96 points a tile (a z0 tile holds
+~70,000 cells) and not counted as sequences: the panel says to zoom in.
+A tile decodes in slices of about 8 ms, the page getting a turn between
+them (a 2 MB z10 tile is ~200 ms of work). A busy API (429/503) holds the
+tiles back for its Retry-After, which the browser cannot read here (the API
+exposes no headers), so the wait doubles from 5 s to 5 minutes until it
+answers; an answer may take as long as it keeps arriving (silent for 15 s
+is given up), so a slow link still gets its megabyte tiles. Both
+filters apply: lines carry their day and camera type, and a cell stays while
+it holds pictures of the kind asked for (cells are undated). A click on a
+line asks the core (`actions.openNearest`) for that sequence's picture
+nearest the click, within the camera height / 100 (50–400 m: from high up
+a click lands well off a line), without framing, then any sequence's within
+50 m. Each lookup is two searches side by side, ranked by distance in the
+browser: `place_position` (nearest first, but even at
+`place_fov_tolerance=180` it leaves out pictures looking away from the
+point) and a bounding box (those too, roughly nearest first, so 20 are
+asked for: ~60 kB, against ~600 kB for 100); the filters go to both (`filter=field_of_view=360`, `datetime=<since>/..`). A line is dated
+by its sequence's first day, so a sequence still growing can hide under
+SINCE; a line with no camera type or day stays drawn. Lines keep the
+decoded longest-first order under the per-tile cap (`keepOrder`). Once the picture is on screen
+its sequence is highlighted and drawn as cones from the z15 tiles around it
+(their `pictures` layer, ~110 bytes a picture, against ~7.5 kB for a STAC
+item), plus the neighbours within 150 m of an edge, on their own connection
+(coverage tiles take three, searches two); each tile's list for the sequence
+is kept. The open picture's own tile draws at once and the neighbours join
+as they arrive; one that fails is not counted, so a picture opening in it
+re-centres the cones there. The cones re-centre when a picture opens outside the tiles
+they were drawn from, judged from the moment their load starts, and centre
+only on a picture actually shown (never on a lookup that came back after
+the user moved on); a lookup nobody waits for any more is stopped. ‹ › follow the picture's own `prev`/`next`
+links, so stepping costs one small search per picture. The viewer shows the
+2,048 px SD derivative (equirectangular for a 360° picture, decoded at
+2,048 × 1,024) and swaps in the HD original only when the viewer is wider
+than SD (flat) or, for a panorama, expanded; once, shrunk while it decodes.
+When SD fails a flat picture falls back to the thumbnail, and to the
+original only in the expanded viewer. Every download of a photo, first or
+sharper, stops when another opens or the viewer closes. Originals wider than
+8,192 px are never fetched; a file's header (JPEG, PNG, WebP, GIF) is read
+before it decodes, and one declaring more than 64 MP or 16,384 px a side
+is refused undecoded, as is an `<img>` that decodes larger and any file
+over 48 MB. The caption names every
+producer (an uploading app and its photographer; never an account named by
+an email address), or else the instance holding the picture ("via
+panoramax.ign.fr"), and the picture's licence (CC BY-SA 4.0, Licence
+Ouverte 2.0…; StreetPose `license`), and links to the picture in the
+Panoramax viewer. Esc anywhere in the docked viewer clears the selected
+sequence before the panel can take it (KartaView too). After a GPU reset
+the viewer draws the same picture again itself (`onReopen`), leaving the
+core's lookups alone. The MCP globe panel allows the meta-catalogue and the
+three biggest instances; a picture on another instance shows only in the
+app.

 - The internal Context coordinator is available in every visual style. Its dedicated right-side `CONTEXT` chooser exposes the neutral shell; the coordinator is not duplicated in Data Layers and does not enable a live-data dependency until a mode is selected.
 - The expanded `CONTEXT` view offers mutually exclusive `CONTACTS` and `SPACE MISSIONS` modes. Selecting `CONTACTS` enables the context-owned Flights, Military Flights, AIS Vessels, and Mapped Installations dependencies only when they are not already user-enabled; selecting `SPACE MISSIONS` enables the recent-launch layer and its Satellite dependency. `CONTACTS` cycles the nearest supported contact of whatever type is selected. Satellites are deliberately excluded from those Awareness cohorts and keep their own tracking UX. Selecting the active mode again returns to the neutral chooser and releases only mode-owned dependencies.
 - If a civilian or military aircraft is already tracked when `CONTACTS` becomes operational, that source-owned track is adopted as the Context subject before nearest-contact autofocus. Context rechecks the tracker after its dependencies settle, so a newer selection wins, while an explicit clear during activation prevents fallback from silently selecting a replacement. Cockpit entry remains unavailable until that Context transaction has settled, so its camera takeover cannot clear Cesium tracking before adoption. Adoption does not recreate tracking or transfer camera ownership; it initializes the normal 250 km ring, history, proximity results, and Cockpit Previous/Next state for the original aircraft.

+- `SEARCH NEARBY SITES` retains the bounded OSM results and makes one user-initiated, view-biased Google Maps Places text search for “military installation.” Google results are source-stamped, deduplicated against OSM by rounded location/name, and remain mapped context rather than operational claims. If Places is unavailable or the API is not enabled for the supplied key, OSM context remains available. A view across the antimeridian is searched around its own centre, with a radius from its real width.
 - 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. 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. Clear Selected Layers reserves its complete captured OFF set before sequential teardown; a newer absolute request of any origin supersedes only its layer reservation and remains authoritative. A rejected layer teardown retains the truthful enabled state, rolls already-stopped siblings back to the captured pre-entry set, and aborts replay; rapid exit/re-entry serializes the full Satellite enabled-state and parameter restore before a new snapshot is taken. Contacts remains additive and restores user-enabled layers normally.

 - **Modes, pins and the preview.** The mode is explicit: `image` (one pinned day, slot `a`), `basemap` (that day on the left of a swipe, the basemap on the right: slot `a` splits LEFT and there is no second layer) and `ab` (day `a` left, day `b` right). `setAssignment(slot, key | null)` / `toggleAssignment(slot, key)` pin and unpin; a day is in one slot at most (pinning it in the other slot moves it) and an empty day cannot be pinned. `setMode()` keeps both pins; `b` only drapes in `ab`. While the mode's first empty slot exists the focused day previews in it: a click at once, arrow keys after 250 ms of quiet (`FOCUS_DEBOUNCE_MS`, one timer, last day wins); an unprobed day is followed and previews when its probe says present, an empty or unknown day never drapes and the previous preview stays. A pin change drops the preview until focus moves again, and unpinning takes that layer off at once. `rankLatest` picks START HERE coverage first (a present HLS day whose footprints cover the box, or have none, beats a newer sliver), then newest with all granules ≤ 20% known cloud, then newest; slivers only as `partial`; else the newest non-empty VIIRS day; it is focused and previewed after each search when nothing is pinned. Escape clears the preview (`clearPreview()`), then cancels the box tool, then blurs — with SELECT BOX armed too, through the tool's `onEscape` interceptor wired in `createApplicationTools`. Pins, mode, box and split changes made in the panel are published with `adoptLayerParams`, never while a share link is being applied.
 - **Rendering.** `rendering.js` owns at most two GIBS layers on the host `src/maps/imageryHost.js` resolves: `viewer.imageryLayers` while the globe shows, the photoreal tileset's `imageryLayers` while it is hidden, or none (the panel says so). Layers are rebuilt on a new host, never re-parented. `MapSourceController.subscribe()` fires after every settled stack switch (silent switches and fallbacks included) and the layer rebinds on it. Tile requests pass a six-slot semaphore of our own (Cesium's global limits are untouched). Under `requestRenderMode` a deferred tile needs a later frame, but a deferral must never request one itself or a stalled tile keeps the scene rendering every frame: a request that finds the semaphore full asks for nothing (the settling request asks for one frame), and a tile Cesium itself deferred goes through one coalesced 250 ms retry. Thumbnails: three fetches at once, sixteen decoded images, least-recently-used where a `get` read is never a use; eviction keeps the probe result. The strip's visible window is probed around the focused card; the pinned and previewed days are probed wherever they sit, at the focused card's priority, so a pin restored or assigned off-screen still drapes.
 - **Esri surface and the swipe.** While any image is on the map (a preview included) the layer holds the map lease (`acquireImageryComparison`, owner `recent-imagery`, `esri-if-photoreal`): on Google 3D the map switches to Esri, because 30 m pixels over 3D buildings do not read, and Cesium's split only works on the globe. The lease is handed back, and Google 3D restored unless the operator changed maps meanwhile, when the last image leaves the map or the layer is disabled; the notice line says so while it holds. While a day is shown the imagery keeps Esri: a manual switch that lands on Google 3D is answered at once with a new lease under the same policy (`keepEsri`), the notice reads `Imagery stays on Esri · CLEAR to use Google 3D`, and the divider never suspends because of a map switch. It re-leases once per switch generation and only for a manual one (`MapSourceController#getSwitchOrigin()` is `manual` for an outside `setStack`, `automatic` for the controller's own fallback or recovery), never for the lease's own switch and never while releasing, so CLEAR and disable still return to Google 3D; a lease another owner holds stays refused. When Esri fails and the controller falls back to Google 3D on its own, the layer lets the lease go without restoring anything, both days drape on the tileset without a swipe and the guidance reads `Esri map unavailable · no swipe`; only the next manual switch to Google 3D takes Esri again, so a failing Esri map is never retried in a loop. Switching between globe stacks (Esri, OSM, Bing) only rebinds. On a tileset host both images drape without a swipe. The split control (`createImagerySplit`, labels A / B, or IMAGE / BASEMAP) exists only while a swipe is live, recentres on every new comparison (not while scrubbing the second day), except once for a split restored from a link. There is no keyboard shortcut (Space is the app's push-to-talk): SWAP (`#ri-swap`, in the controls row, its slot reserved and the button disabled while no swipe is live) trades the two sides, A to the right and B to the left, or the image to the right of the basemap, and a second click restores; the hint reads `Drag the divider · SWAP trades sides`. The swap is not in the share link, and every new comparison starts unswapped. One opacity applies to both drapes. Another owner holding the lease is reported and the images still drape.

+# UI text and translation
+
+Every piece of text a user can see goes through `t()`, `tn()` or `msg()` in code, or a `data-i18n*` attribute in markup. The English text itself is the key. English needs no catalog; other languages live in `src/i18n/locales/<code>.json`. Translators work from [TRANSLATORS.md](./TRANSLATORS.md).
+

+
+```js
+import { t, tn, msg } from '../i18n/index.js';
+
+status.textContent = t('Save keys');
+status.textContent = t('Saved to {store}', { store: storeLabel() });
+
+chip.textContent = tn(missing, '{count} KEY WAITING', '{count} KEYS WAITING');

+
+const FEED_STATE_LABELS = { loading: msg('LOADING'), stale: msg('STALE') };
+label.textContent = t(FEED_STATE_LABELS[state]);
+```
+
+A module the server, tools or other portable code also imports must not load the catalogs: it imports `msg` from `src/i18n/marker.js`, which only marks the text, and the UI translates it with `t()` where it shows it. (Older modules keep a local `const msg = (text) => text`, which works the same.)
+
+`msg()` exists for two reasons. `npm run i18n` finds messages only as string literals inside `t(…)`, `tn(…)` and `msg(…)`, so `t(FEED_STATE_LABELS[state])` alone tells it nothing. And a `t()` call at module load runs before the page has picked its language, so it would freeze the English.
+
+## Markup
+
+```html
+<span data-i18n>Normal</span>
+<button title="Pin visual presets" data-i18n-title>…</button>
+<input placeholder="Search any location..." data-i18n-placeholder />
+```
+
+`data-i18n` replaces the element's text, so put it on the element that directly holds the text, never on a parent with child elements. `data-i18n-title`, `data-i18n-aria-label` and `data-i18n-placeholder` translate that attribute. Markup is translated once at boot, and switching language reloads the page. A module that holds work a reload would lose (an unsaved edit, an open session) registers it with `registerUnsavedWork(() => busy ? msg('unsaved …') : null)` from `src/i18n/index.js`, and the language picker asks before reloading.
+
+## Rules
+
+- **Pass literals.** `t('Close')`, not `t(label)` (unless `label` holds a `msg()` value) and never a template literal with `${…}`.
+- **Use placeholders, not concatenation.** `t('Flying to {place}…', { place })`, not `t('Flying to') + ' ' + place`. Word order differs between languages.
+- **Use `tn()` for counts**, not `count === 1 ? … : …`. Russian has three forms.
+- **Translate the label, not the value.** Layer ids, enums, share-link parameters, API fields, voice tool schemas and feed data (callsigns, vessel and place names) stay as they are; translate only the text shown for them.
+- **No `t()` at module top level.** Keep the English in `msg()` and call `t()` when rendering.
+- **Numbers and dates** go through `formatNumber`, `formatDate`, `formatRelativeTime` and `formatUtcDayMonth` from `src/i18n/index.js`, which follow the active language.
+- **Identical English means identical translation,** unless you give it a context: `t('CLEAR', { context: 'action' })` (a button) is its own catalog entry, `action|CLEAR`, while `t('CLEAR')` (the sky) stays separate. English output is the same.
+- **Text that should stay English** (a brand, a code, a unit symbol) is simply not wrapped.
+
+## After you add or change text
+
+```sh
+npm run i18n                     # what each language lacks or no longer uses, and unmarked UI text
+npm run i18n -- --missing ru     # the missing ru entries as JSON
+npm run i18n -- --prune          # drop entries whose English no longer exists
+```
+
+Changing the English changes the key: the old translation goes unused and the new text shows as missing. Add the translation to every `src/i18n/locales/<code>.json` (or ask a translator), prune, and run `npm test`; it fails until every language is complete.
+
+To see a language, open the app with `?lang=ru`, or use the language picker (the globe button in the bottom-right corner).
+
+An empty translation is reported, and so is one left as the English, plural forms included. When English is right on purpose (a code such as CRT, a product name), list it under the language in `src/i18n/same-as-english.json`.
+
+## Text the check reports as unmarked
+
+`npm run i18n` and `npm test` fail on UI text that is not marked:
+
+- **Markup:** element text without `data-i18n`, and `title`, `aria-label` or `placeholder` without the matching `data-i18n-*`.
+- **Code:** string literals that reach the page without `t()`, `tn()` or `msg()`: assigned to `textContent`, `title` and the like; passed to `setAttribute('title' | 'aria-label' | …)`, `createTextNode`, `showToast` and other notice helpers; assigned to a layer's `error`, `lastError`, `loadingLabel`, `statusMessage` or `status` (a plain `error = …` too); or kept in `label:`, `title:`, `status:` and similar properties. Not reported: declarations (`let status = …`), default values, ternary branches and lower-case codes (`'auth-failed'`). The full list is `JS_SINKS` in `scripts/i18n.mjs`.
+
+Fix it by marking the text. When the text must stay as it is, say so where it lives:
+
+| Case                                                                        | How                                                                      |
+| --------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
+| Codes, units, product names in markup (`0.9 dB`, `ADS-B · 1090`, `OpenSky`) | `translate="no"` on the element; it covers everything inside, as in HTML |
+| Markup whose text code sets through `t()` (a status that starts as `OFF`)   | `data-i18n-runtime` on the element                                       |
+| A literal in code that is not UI copy (a product name, sample data)         | `// i18n-ignore: <reason>` on the line or the line above                 |

+# Translating God's Eye View
+
+Shipped languages: **English** (source and fallback), **Spanish** (`es`) and **Russian** (`ru`).
+
+## How it works
+
+The English text is the key: code calls `t('Save keys')`, and markup marks elements with `data-i18n`. How developers mark text is in [I18N.md](./I18N.md).
+
+Every other language is one flat JSON file, `src/i18n/locales/<code>.json`, keyed by the English text:
+
+```json
+{
+  "Save keys": "Сохранить ключи",
+  "{count} cameras": {
+    "one": "{count} камера",
+    "few": "{count} камеры",
+    "many": "{count} камер",
+    "other": "{count} камеры"
+  }
+}
+```
+
+A `tn()` entry is keyed by the English plural form and holds one string per `Intl.PluralRules` category of that language. A missing entry falls back to English.
+
+The page picks its language from `?lang=`, then the choice stored by the language picker (the globe button in the bottom-right corner), then the browser languages, then English. `?lang=` is not stored, and copied share links leave it out. Switching reloads the page.
+
+## The check
+
+```sh
+npm run i18n                      # what is missing, unused or broken, per language
+npm run i18n -- --missing ru      # missing ru entries as JSON, ready to translate
+npm run i18n -- --prune           # drop entries the code no longer uses
+```
+
+`npm test` runs the same check. It fails on a missing, empty or unused entry, on placeholders that differ from the English, on a missing plural form, and on text or plural forms still in English. The `--missing` template fails until every entry is translated. If an entry is right in English (a code such as CRT, a product name), add it under your language code in `src/i18n/same-as-english.json`.
+
+Changing English text changes its key: the old translation becomes unused and the new text shows as missing. Translate it and prune.
+
+## Fixing a translation
+
+Edit `src/i18n/locales/<code>.json` and run `npm run i18n`. To see your change, open the app with `?lang=<code>`.
+
+## Adding a language
+
+1. Create `src/i18n/locales/<code>.json`, fill it from `npm run i18n -- --missing <code>` (start from `{}`), and translate every entry.
+2. Import it in `src/i18n/index.js` and add it to `CATALOGS`.
+3. Add the code to `LOCALES` and its own-language name to `LOCALE_NAMES` in `src/i18n/locale.js`. Right-to-left languages also go in `RTL_LOCALES`.
+4. Add `src/i18n/locales/<code>.json` next to `ru.json` in `scripts/package-boundaries.json`.
+5. Write `docs/translations/<code>.md`: glossary, plural forms, units and style (copy the structure of `ru.md`).
+6. Run `npm run i18n` and `npm test`, then check the panels in the app at narrow widths.
+
+## Rules
+
+- Keep every `{placeholder}` name exactly as in the English: do not rename, drop or add one. Its position inside the sentence follows the grammar of your language, e.g. `"{accepted} of {raw} records accepted"` → `"принято записей: {accepted} из {raw}"`.
+- UPPERCASE English stays UPPERCASE. Short labels, chips and HUD readouts should stay short; prefer an abbreviation over a wrapped line.
+- Keep the separators `·`, `—`, `→`, `↗`, `…`.
+- Leave product, provider and data names in their original form: Google Maps, Cesium ion, OpenAI, ChatGPT, NASA FIRMS, USGS, OpenSky, ADS-B, AIS, CCTV, HUD, TomTom, OpenStreetMap, Mapillary, and keyboard keys (Space, Esc, H, 1–9).
+- Units follow the language's convention; see the language notes.
+
+## Never translated
+
+These are contracts, not copy: layer ids and registry keys, status enums and other machine values (translate only the label shown for them), share-link and hash parameters, `?lang=`, storage schemas, API fields, voice tool names and schemas, provider and dataset names, data from feeds (callsigns, vessel, satellite, station and place names, headlines), attribution, console diagnostics, and user-authored content.
+
+## Language notes
+
+Each language keeps its glossary, plural forms, units and style in its own file, `docs/translations/<code>.md`: [Spanish](./translations/es.md), [Russian](./translations/ru.md). Read it before translating, and add a term there when you settle on one.

+# Spanish (`es`)
+
+Catalog: `src/i18n/locales/es.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+## Style
+
+- Neutral Spanish that reads naturally in Spain and Latin America; avoid regionalisms.
+- Address the user with informal "tú" imperatives: «Añade», «Activa», «Elige», «Pega», «Inténtalo de nuevo». Tooltips that name an action may use the infinitive: «Expandir el panel», «Restablecer la cámara».
+- Sentence case, not Title Case: "Live Flights" → «Vuelos en vivo». UPPERCASE English stays UPPERCASE: «EN VIVO», «SIN DATOS».
+- Quotes inside Spanish text are straight double quotes: «¿Eliminar el plano "{shot}"?». Questions and exclamations open with ¿ and ¡.
+- Short labels, chips and HUD readouts stay short. A standard abbreviation with a period beats a wrapped line: ANT., SIG., VEL., DIST., SINCR., cám., cob.
+- The HUD codes HDG, BRG, CRS, FOV, DEST, SPD, RANGE and ALT stay in English everywhere, as in cockpit avionics. Words used in a sentence are translated: heading → «rumbo», range → «alcance».
+- Keyboard keys stay in English: Space, Esc, Enter, Tab, Shift, H, 1–9 («Mantén pulsado Space para hablar»).
+- Units: km, m, km/h, m/s, kn (knots), ft (feet), h, min, s; in UPPERCASE text KM, KM/S, KN, FT, MIN, H. "m" is always metres, so minutes are «min» («hace 5 min»). MW stays MW. `°` and `%` stay.
+- "ago" goes before the time: «hace {count} min». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add «hace» again.
+- Spelling: «costo» (not «coste»).
+
+## Plurals
+
+A `tn()` entry needs three forms. `Intl.PluralRules('es')` picks:
+
+| Form    | Counts                                 | Example              |
+| ------- | -------------------------------------- | -------------------- |
+| `one`   | 1                                      | 1 cámara             |
+| `many`  | 1 000 000, 2 000 000… (exact millions) | 1 000 000 de cámaras |
+| `other` | everything else: 0, 2–999 999, 1.5…    | 3 cámaras            |
+
+The `many` form is the `other` text with «de» after the number: «{count} de cámaras cargadas», «{count} DE CLAVES EN ESPERA».

+ * SCT's own `RenderService` frame link is a special case, for two stacked

+ *  1. It always 302s to `TransitCamera`, on a Location the upstream
+ *     hardcodes as plain http even when RenderService itself was requested
+ *     over https. fetchWithinHost (media.js) only follows same-origin
+ *     redirects — same scheme included, by design, to stop an upstream
+ *     steering a host-pinned request into a plaintext downgrade — so that
+ *     hop is refused and the camera would render as a placeholder.
+ *  2. mct.gencat.cat's TLS setup itself does not complete a handshake with
+ *     Node's fetch/OpenSSL (`ERR_SSL_WRONG_SIGNATURE_TYPE`) even though it
+ *     is reachable over https from other clients (e.g. curl) — an upstream
+ *     server misconfiguration this proxy cannot route around.
+ * TransitCamera answers the frame directly over **http**, no redirect, and
+ * that is the only transport this host actually serves to this runtime — so
+ * this builds that URL itself from RenderService's `sctidcam` id instead of
+ * registering the (https, then-redirecting) RenderService link. The
+ * `sctidcam` id must be a bare image filename (CATALONIA_SCT_CAMERA_FILE_RE).
