 - **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, 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).
 
 - **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)).

 - **adsbdb enrichment.** `/api/adsbdb` resolves an ICAO hex to aircraft type, model name and registration, and the tracked flight's callsign to an airline and an origin/destination pair. Fan-out is deliberately small because adsbdb is a free community API that publishes no quota: at most 4 requests in flight, dispatches dripped to roughly 5/s, and each key asked for at most once per session, with route lookups reserved for the tracked aircraft. The dev-server proxy caches each key for 24 hours in `.gev-cache/adsbdb.json`, negative answers included, so fresh entries survive server restarts. That gitignored cache remains local to the deployment and is not bundled with this repo. adsbdb publishes no general service license; its README says the route data may not be copied, published, or incorporated into other databases without the explicit permission of David J Taylor, Edinburgh. Deployers are responsible for obtaining any permission their use requires. Enrichment is best-effort and fail-silent — a flight that gets no answer keeps what the flight feed already gave it.
 - **Launch Library 2.** `/api/launches` makes a server-side rolling-30-day query against the supported v2.3 detailed launch endpoint, caches successful responses for 15 minutes in memory and on disk, and serves the last successful response during a throttle or transient outage. Anonymous access is limited to 15 calls/hour; deployments can provide `LL2_API_TOKEN` for authenticated access. The Space Devs' published terms permit using and sharing the API data in any form, ask users not to forward it without adding value, disclaim complete accuracy, and encourage—but do not require—attribution. This app keeps a courtesy credit. Payload and stage/recovery records are shown only when supplied. Failed launches expose their source status and never receive fallback orbit geometry or a live/estimated marker. LL2 supplies launch context and event timing, not continuous ascent telemetry or live orbital state.
 - **TfL JamCams.** The camera list comes from the keyless `api.tfl.gov.uk` endpoint (an optional `TFL_APP_KEY` raises its rate limit); frames come from TfL's public S3 bucket. The "Powered by TfL Open Data" attribution is required by TfL's terms and is registered in the Data attribution popover.
-- **Ontario 511 CCTV.** The camera list comes from the keyless `511on.ca/api/v2/get/cameras` endpoint; frames are server-registered still images under `511on.ca/map/Cctv/`. The source is live-fetched at runtime and attributed under the Open Government Licence - Ontario.
+- **Ontario 511 CCTV.** The camera list comes from the `511on.ca/api/v2/get/cameras` endpoint, which now requires a free developer key (`ONTARIO_511_API_KEY`: sign up at 511on.ca/my511/register, then request it while logged in at 511on.ca/developers/doc; throttled to 10 calls a minute). Without the key the pack is skipped. Frames are server-registered still images under `511on.ca/map/Cctv/`. The source is live-fetched at runtime and attributed under the Open Government Licence - Ontario. Access is governed by Ontario 511's Developer's Access Agreement (511on.ca/developers/resources): the data stays under the Open Government Licence - Ontario unless otherwise specified; key requests are reviewed case by case and ask for the intended use and any third parties that will receive the data; attribution by link to 511on.ca is encouraged, and the Ontario 511 logo may not be altered or used to imply endorsement (this app links and shows no logo); and the data is provided "as is", a disclaimer distributors should pass on, which the credit does.
 - **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.

 - **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`.
+- **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`.
 - **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. The DATA.GOV.HK Terms of Use require attribution to the Government / Transport Department / DATA.GOV.HK.
 - **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.
+- **Kartverket ground heights for Statens vegvesen cameras.** The camera feed's points are 2D, so the loader asks Kartverket's keyless point-height API (`ws.geonorge.no/hoydedata/v1/punkt`, CC BY 4.0) for the terrain height at each camera. Requests carry 20 points: the API accepts 50, but above ~20 it answers the extra points from contour lines (`hoydekurver`, metres to ~20 m off) or not at all. Eight requests run at a time, about 36 for the whole country: a cold lookup took 6–13 s in testing (single requests 0.6–9.5 s). Answers are matched by the coordinates the API echoes and recorded only for points that request asked about. Over water the API returns the sea-floor depth (`dybdekurver` or `Havflate`), which is replaced by 0 m, the water surface; for the ~14 bridge cameras that is below the deck, but much closer than the sea floor or the flat prior. Heights are cached in memory by position for the life of the server, and points with no height (a few ferry quays and bridges, or a point a 200 answer leaves out) for 6 h, so the 15-minute catalog refresh only asks about new or moved cameras. The first failing request (a 408, 429 or 5xx, a network error, a request over 10 s, or an unreadable or oversized body) stops the lookup, with no retries, and no new lookup starts until the backoff ends (Retry-After when sent, else 30 min, longer than the refresh; bounded to 1 min–1 h). Any other 4xx marks that request's points as having no height and the lookup carries on. The whole lookup has a 30 s deadline; a lookup cut short by it resumes on the next refresh without a backoff. The lane waits at most 12 s, counted from the start of the loader, and only when more than 10% of the cameras have no answer yet; a few new cameras or expired misses are looked up in the background. A slower lookup keeps filling the cache, and the cameras it had not reached keep the flat prior until the next 15-minute refresh (about 190 of 865 on one slow first run). Only coordinates are sent, with the same User-Agent as the other CCTV requests. `CCTV_VEGVESEN_HEIGHTS=0` turns the lookup off. The Kartverket credit, with a note that heights over water are set to 0 m and heights are rounded to 0.1 m, is shown beside the Statens vegvesen entry 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.

 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.

-On Google 3D (`photoreal`) at street zoom (in below 1,400 m above ground, out
-above 1,800 m) the surface mode switches from `draped` to `terrain`: draped
-lines land on roofs and tree tops, so `groundCast.js` instead places lines,
-cones and the marker 2 m above the bare earth from `/api/terrain/heights`, and
-the mesh hides what is behind buildings and trees. A tile is drawn draped until
-its heights arrive; a geoid fallback leaves it draped. Within 900 m of the
-camera, `meshSampler.js` samples the rendered surface (`scene.sampleHeight`,
-~11 m cells, nearest first, 6 ms idle budget) so lines also follow trenches,
-steep streets and roads under trees. It uses the mesh floor's rules (the
-visible tileset has finished streaming, a real bare-earth prior, the shared
-mesh window) and probes a cell again once the camera is half as far from it,
-down to 40 m, so coarse early samples are replaced as finer tiles load. A
-failed probe keeps the last good sample and distance and is retried after the
-miss cooldown. Roads on elevated decks are still drawn at

They now call `selectTrackedSubjectContext` / `refreshTrackedSubjectContext` / `clearTrackedSubjectContext` (`src/data/contextStore.js`) on select / poll / deselect. **Invariants: (a)** that write path must NOT dispatch `gev:entity-selected` — tracking layers already own an event lane and a second one makes two surfaces fight over one subject; **(b)** exactly one record per tracking layer, because a frozen snapshot of a moved contact must never reach the visible-entity scan; **(c)** precedence is recency, not layer — one slot, last selection wins, so clicking an overlay entity supersedes a tracked plane as the voice subject while the plane stays tracked.

-# Running the mobile demo
-
-## Start
-
-```sh
-npm install
-npm run dev
-```
-
-Open `http://localhost:4173/mobile/` in Chrome. Open DevTools, turn on the device toolbar (Cmd+Shift+M), and pick a phone (iPhone 14 Pro Max is close to the 17 Pro Max at 430×932) or an iPad Pro (1024×1366). The two-pane tablet layout starts at 600 px wide.
-
-No keys are needed. Load the page once before presenting: the first load compiles and caches, and later loads paint Today in under a second from the last good snapshot.
-
-## Presenter keys
-
-Press `.` to open the director. Press a key to jump to a beat. Each beat sets up its own state, so they can be run in any order.
-
-| Key | Beat | What to say |
-| --- | --- | --- |
-| 1 | Today | The daily brief: since you last looked, today's Moment, your sky, your watch. |
-| 2 | Your sky now | Everything above you this minute, from live ADS-B and orbital elements. |
-| 3 | The Empire State Moment | A 4D reconstruction: helicopter tracks, sealed captures with view cones, chat and the record on one clock. Illustrative. |
-| 4 | The Live lane, with hearts | Twitch-style chat over the city; reactions rise from where people are. Simulated chat. |
-| 5 | Need eyes | A room asks for coverage; the first sealed answer earns the byline and Signal. |
-| 6 | Capture | Look, Witness, Live and Upload, signed on the device. |
-| 7 | Dossier of a live aircraft | Gotham-style: identity, live state, track, links, receipts. Real data. |
-| 8 | Link graph | Everything that thing touches, synchronized with the globe. |
-| 9 | Time machine at 60× | Replays a real bundled recording of London, NYC and the Gulf. |
-| 0 | Clip this Moment | Select a range and clip it into a shareable Moment. |
-| - | An alert, calmly | Severity-gated alert rules on live data. |
-| = | Search to dossier | Search "7700" (or "ISS" if nothing is squawking) and open the result. |
-
-`Esc` closes the top sheet. The director has a **Reset demo** action.
-
-## What's real
-
-| Real | Illustrative or simulated |
-| --- | --- |
-| Live aircraft, military, satellites, quakes, cyclones, fires, radar, lightning, wind, air quality, GNSS interference, transit, public cameras | The Empire State Moment (synthetic tracks over real NYC footprints) |
-| Detections (circling, squawks, quake clusters) on live data | Chat in the Live lane, example posts, crews, and other contributors |
-| The time machine's recording (this session's polling plus a bundled real recording from 23 Oct 2026, 08:25–11:06Z) | Need eyes requests from other people |
-| Capture signing, hash chains and verification (WebCrypto on this device) | The room clerk (rules, not a model) |
-
-Every illustrative or simulated surface carries a label in the app.
-
-## Rehearse
-
-Run the beats once on the presenting Mac before the meeting. On first load the keyless terrain host can be slow; if a close-up stays black for more than a few seconds, the engine falls back to flat terrain on its own.
-
-Refresh the bundled data while `npm run dev` is running: `node mobile/demo/capture-snapshot.mjs --base http://localhost:4173` for the snapshot, and `node mobile/demo/capture-history.mjs --base http://localhost:4173 --minutes 150` for the recording (it writes every 5 minutes; behind a proxy, prefix it with `NODE_USE_ENV_PROXY=1`).

-## 1. The goal, rewritten
-
-> Build the app people open **the moment something happens in the real world**, and the app they open **when nothing is happening** just to look.
->
-> It must make 40+ live layers feel like one calm surface on a 6.9" phone, unfold into a two-pane instrument on a foldable, scrub the planet through time like a video, and let anyone with a phone add **signed, sensor-rich observations** that make reconstructions of real events harder to fake.
-
-Five commitments fall out of that sentence:
-
-1. **Situations, not layers.** The public does not think in feeds. They think in _things worth watching_: a cyclone, a launch, a flood, a chopper school, a stadium, an airport at rush hour. The home screen is a feed of situations. Layers are the ingredients a situation turns on for you.
-2. **Click _into_ the world, not to the next card.** Opening a card is a spatial transition: the card's thumbnail is the globe, and it expands into the live globe at that place, at that time, with that situation's lenses on. Closing it folds the world back into the card. No page loads, no white flashes.
-3. **Time is a first-class axis.** Every view has a scrubbable timeline (past ← now → forecast). Situations carry their own time window. Reconstructions are 4D: space × time × evidence.
-4. **Truth needs walls.** Captures from this app are cryptographically signed at the moment of capture and carry the full session: IMU trace, GPS, heading, timestamps, device and sensor metadata, a hash chain. Foundation **observations** are kept separate from the **hypotheses** people (and AI) layer on top, and every change is in an inspectable audit trail.
-5. **Cinematic by default, performant always.** Day and night blend across the terminator. High orbit gets the planetary treatment (cloudless day mosaic + night lights + atmosphere + bloom); close in, it becomes photorealistic 3D. The post chain is budgeted for a phone GPU, adapts to thermal state and battery, and drops to a still frame when nothing moves.
-
-## 2. Information architecture
-
-Five tabs. Capture is a tab, not a floating action, because it is a _mode_ with its own full-screen surface (HIG: tab bars navigate between peer areas; capture is a peer area here, as it is in Camera-first apps).
-
-| Tab         | SF-style glyph                          | Job                                                                                                                                                                                                                                                                                                          |
-| ----------- | --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
-| **Now**     | `dot.radiowaves`                        | A two-column, RedNote-style masonry feed of live and recent situations. Each card is a living thumbnail: real imagery of the place, live counters, a pulse when it changes. Sections: _Happening now_, _Near you_, _Reconstructions_, _Always on_ (chopper schools, busy airports, ISS, port of Rotterdam…). |
-| **Globe**   | `globe.americas`                        | The window. Full-bleed globe, the lens dock, the time ribbon, search. This is the expert surface.                                                                                                                                                                                                            |
-| **Capture** | `viewfinder`                            | Two modes on one dial: **Look** (AR — the God's-eye view projected around you: aircraft, satellites, ships, quakes as overlays on the camera, aligned by compass + gyro) and **Witness** (your phone becomes an eye for the God's eye: signed photo/video with IMU, GPS, heading, depth when available).     |
-| **Threads** | `point.3.connected.trianglepath.dotted` | Reconstructions people are building together: observations, hypotheses, AI refinements, and the ledger.                                                                                                                                                                                                      |
-| **You**     | `person.crop.circle`                    | Your captures and their seals, holograms you left in places, situations you follow, alert radius.                                                                                                                                                                                                            |
-
-The iOS 26-era shell: a floating glass tab bar that shrinks to a pill while you scroll the feed and expands when you stop; a **tab-bar accessory** shows the one situation you are following live ("Typhoon · 185 km/h · 2 min ago"), like a now-playing bar for the planet.
-
-## 3. Interaction model
-
-- **Card → world (hero transition).** The tapped card's frame animates to full-screen while its static thumbnail cross-fades into the live globe already flying to the situation camera. The sheet rises to the medium detent with the situation brief. Swipe the sheet down or tap the back chevron to fold back to the card. Reduced Motion: cross-fade only.
-- **Sheets with detents** (peek ≈ 96 pt / medium ≈ 45% / large ≈ 92%). Peek shows the headline numbers; medium shows the brief and the evidence strip; large shows the full thread. Dragging the globe while the sheet is at medium collapses it to peek, so the world always wins.
-- **Lens dock.** 40+ layers live in eight families. The dock shows _family_ chips (Sky, Sea, Orbit, Hazards, Eyes, Ground, Weather, Infra); tapping a family opens a Control-Center-style grid of its layers with live counts. Long-press a family to solo it. The globe also curates by **semantic zoom**: at planetary altitude only aggregates render (density glows, cyclone cones, fire clusters); individual glyphs appear as you descend.
-- **Time ribbon.** A thin, haptic-detented scrubber above the tab bar: −72 h ← NOW → +120 h (forecast). Event pips sit on the ribbon (the quake, the launch, the flood crest). Dragging fast moves in hours; slow, in minutes. Tapping NOW snaps back to live with a single tick haptic. In Live the ribbon breathes.
-- **Pick anything.** Tap a contact on the globe: it's highlighted, a trail draws, and a compact card offers **Follow**, **Ride** (cockpit/bridge camera), **Nearest eye** (closest live camera), **Thread** (start or join a reconstruction).
-- **Foldables & large screens.** Width ≥ 600 pt switches to a two-pane layout: feed/thread list on the leading pane, globe on the trailing pane; selection in one drives the other. With a vertical hinge (`horizontal-viewport-segments: 2`) the panes split exactly at `env(viewport-segment-right 0 0)` so nothing renders under the fold. Half-folded (tabletop, `vertical-viewport-segments: 2`): globe on top, controls and timeline on the bottom half, like a laptop.
-- **One-handed reach.** All primary controls sit in the bottom 40% of the screen. Search lives in the tab bar row (iOS 26 pattern), not at the top.
-- **Haptics & sound.** `navigator.vibrate` where available for ribbon detents and capture seal; never decorative.
-
-## 4. Visual language
-
-- **Ground:** near-black with a blue bias (`#05070B`), never pure grey. The globe is the only light source; UI is glass over it.
-- **Glass:** `backdrop-filter: blur(24px) saturate(1.6)` panels with a 0.5 px inner highlight, 22–28 pt continuous corners, no drop shadows on glass.
-- **Signal colors** carry meaning and are reserved: Sky `#7CC4FF`, Sea `#38E1C6`, Orbit `#C9A7FF`, Hazards `#FF6A3D`, Eyes `#FFD166`, Ground `#9BE15D`, Weather `#8AB4F8`, Infra `#B8C0CC`. Live = a soft pulse; Stale = desaturated with a dotted outline; Signed = a seal glyph in warm gold.
-- **Type:** the system UI face (SF Pro / Roboto Flex via `system-ui`) for UI; tabular numerals for every live readout; a monospace for coordinates and hashes only. Large titles (34 pt) on Now and Threads, collapsing on scroll.
-- **Tufte rule for reconstructions:** maximize data-ink. Small multiples for before/after, sparklines in-line with text, direct labels instead of legends, uncertainty drawn (cones, bands, dotted where inferred), and every number carries its source and age.

-| Data             | each layer has an LOD rule (aggregate above 2,000 km altitude, glyphs below) and a visible-count cap                                                                                  |
-
-## 6. Capture and provenance
-
-A Witness capture produces a **sealed bundle**:
-
-```
-bundle = {
-  media:     JPEG/WebM bytes                                   → sha256
-  session:   { start, end, imu: [{t, α, β, γ, ax, ay, az}], gps: [{t, lat, lon, acc, alt}], heading }
-  context:   { device, ua, screen, timezone, network-time-offset }
-  prev:      sha256 of this device's previous bundle            (hash chain)
-  hash:      sha256(canonical(media hash + session + context + prev))
-  signature: ECDSA P-256 over hash, key generated on device, non-extractable, stored in IndexedDB
-}
-```
-
-In a native build the key lives in the Secure Enclave / StrongBox and is bound to App Attest / Play Integrity, and the bundle is written as a C2PA manifest. The prototype does the browser-equivalent with WebCrypto so the flow, the data and the verification UI are real. Verification recomputes the hash, checks the signature against the device public key, and checks IMU/GPS plausibility (the motion trace must agree with the image's horizon and the compass heading; the GPS track must agree with the time). None of this proves truth. It raises the cost of lying.
-
-## 7. Reconstructions (Threads)
-
-A reconstruction is a document with three strata, always drawn in this order:
-
-1. **Observations** — machine-sourced or signed: ADS-B/AIS tracks, satellite imagery, seismograph readings, signed captures. Immutable; each has source, time, hash.
-2. **Hypotheses** — claims that connect observations ("this clip was filmed from the north bank at 14:02", "the aircraft entered a hold at 2,100 ft"). Each has an author (person or AI), confidence, the observations it cites, and agreement/disagreement counts.
-3. **Narrative** — the story view: a camera path through space and time that cites hypotheses.
-
-Collaborative AI prompting happens on stratum 2: a participant asks the model to refine ("align the witness clip to the corridor using the bridge as a landmark"). The model's output is a _proposed hypothesis_ with its prompt, model, inputs and diff recorded in the ledger. Nobody edits an observation; you can only cite, dispute, or supersede a hypothesis. The ledger is a hash chain anyone can export and verify.
-

-Live today with the repo's feeds: tropical cyclone tracks · largest quake in 24 h · fire clusters in Europe/California · military air activity over a region · ISS pass over you · busiest airport now · helicopter school circuits (Fort Novosel) · launch countdowns with trajectory · Bhote Koshi flood reconstruction · ships queuing at Suez/Panama/Singapore · GNSS jamming hot spots · transit at rush hour.
-
-Ten more to build: stadium/concert 4D reconstructions from crowd captures · storm chasers with signed dashcams · emergency squawk 7700 replays · air-show displays · marathon/route races with runner trackers · eclipse path watch parties · aurora nowcasts with sky captures · ferry crossings and harbour pilots · wildfire smoke vs. air quality vs. hospital load · building-climb or rooftop incidents reconstructed from ADS-B news helicopters + witness video · protest/march route documentation with signed captures · volcano webcams vs. ash advisories · delivery-drone corridors (Prime Air style corridor replays).

-## 11. Round two: from weather app to God's Eye
-
-Review notes on the first build: the feed showed one kind of picture (open ocean under a cyclone), the app read as a weather app, there was nowhere for people to talk, and capture stopped at a sealed photo. This section is the response. Where it disagrees with §1–§10, it wins.
-
-### 11.1 Identity: space → sky → ground → inside
-
-The app's subject is altitude. Every surface tells you **where the sensor is** and **how high it is**, from orbit down to street level and finally inside: a room, a cockpit, a person's own capture. That is the brand, and it replaces the weather-app palette of blue gradients and big temperature-style numbers.
-
-| Altitude band             | Sensor                                                          | Telemetry burned into the frame               |
-| ------------------------- | --------------------------------------------------------------- | --------------------------------------------- |
-| **Orbit** · 400–36,000 km | satellites, ISS, launches, weather satellite IR                 | `ORBIT · 412 KM · 7.66 KM/S · PASS 21:04`     |
-| **Sky** · 0–15 km         | ADS-B aircraft, helicopters, military, radar returns, lightning | `SKY · FL350 · 487 KT · SQ 7700`              |
-| **Ground** · 0 m          | CCTV, traffic, transit, fires, quakes, floods                   | `GROUND · CAM 0412 · I-5 S · 14:02:11Z`       |
-| **Inside** · you          | signed captures, live broadcasts, holograms, conversations      | `WITNESS · SEALED · ±4 M · 1.2 KM FROM EVENT` |
-
-Visual rules:
-
-- **Sensor framing.** Feed cards and the globe chrome use corner brackets, a hairline reticle, and a monospace telemetry strip burned into the image (coordinates, MGRS, UTC, sensor id, altitude). It is restrained: one strip per card, never a full military HUD.
-- **Type.** Display: the system face, tight and heavy. Telemetry: a monospace face (JetBrains Mono, which the desktop app already loads) in small caps with tabular numerals. The monospace face is the voice of the instruments, not of the UI.
-- **Color.** Ground stays near-black. Each altitude band has one signal hue: Orbit violet, Sky ice-blue, Ground amber, Inside warm gold for sealed. Hazard red is reserved for things that hurt people. No blue-gradient cards.
-- **Imagery is evidence.** Thumbnails are composited from the layers that actually describe the situation (§11.2). A picture of empty ocean is never acceptable.
-
-### 11.2 The feed: compelling, diverse, real
-
-The Now feed is the global equivalent of a neighborhood safety feed: it tells you what is happening, where, how close, and who saw it. Diversity is a requirement. The feed mixes **card archetypes** and **altitude bands**, and never puts two cards of the same archetype or band side by side when it can avoid it.
-
-Card archetypes:
-
-1. **Sensor card**: a composited frame. The base is the Esri image of the place or GIBS satellite IR. On top go the real data layers (radar, lightning strikes, cyclone cone and track, flight trails, quake rings, fire hotspots and smoke direction from wind), with sensor framing and telemetry burned in.
-2. **Eye card**: a real frame from the nearest public camera (`/api/cctv`), with a LIVE timestamp, camera id, and direction of view. This is the most Citizen-like card: you see the street.
-3. **Track card**: one moving thing, such as an aircraft squawking 7700, a helicopter on its 14th circuit at Fort Novosel, or the ISS crossing your night sky. It shows a trail, a big readout, and a "ride along" call to action.
-4. **Number card**: one striking fact with a sparkline. Examples: "4,812 lightning strikes in the last hour over the Gulf", "GNSS jamming over the Baltic, 340 aircraft affected".
-5. **Witness card**: a signed capture or a live broadcast from a person. It shows the seal, the distance from the event, and the reply count.
-6. **Room card**: a conversation that is heating up. It shows the top claim, its status (_Confirmed by 3 signed captures_ / _Disputed_), and the participants.
-
-Situation genres to source from keyless layers. Each card must say its source:
-
-- Cyclones (NHC cone, track and wind radii, GIBS IR)
-- Severe-storm cells (radar plus lightning density)
-- Heavy rain over a major city (radar)
-- Jet-stream wind anomalies (GFS wind)
-- Quakes (USGS, with intensity rings)
-- Wildfires (FIRMS or EONET, with smoke direction from wind)
-- Emergency squawks (7500, 7600, 7700)
-- Military activity
-- Helicopter schools
-- Launches (pad and trajectory)
-- ISS and Starlink passes over the viewer
-- GNSS interference (`/api/gnss-integrity`)
-- Transit at rush hour (`/api/transit`)
-- Busiest airport arrivals
-- Live public cameras at famous places (Times Square, Shibuya, Tower Bridge where available, otherwise any busy feed)
-- Ship queues at chokepoints
-- The Bhote Koshi reconstruction
-
-### 11.3 Discourse: every situation has a room
-
-People will talk about events anyway, on other platforms and without the evidence. The room puts the conversation **on the evidence**: anchored in space and time, and graded by how it was observed.
-
-- **Structured posts.** Each post is one of: **Witness** (I saw or recorded this), **Context** (background, a link, a map), **Question**, **Correction**, or **Prediction**. The kind is chosen in the composer and drawn as an icon. Questions float to the top until answered.
-- **Anchored.** A post can pin a place (a dot on the globe) and a time (a pip on the time ribbon). Tapping a post flies the globe there and scrubs the ribbon to that moment. Pinned posts appear in 3D as small speech glyphs at their location.
-- **Earned badges, not follower counts.** Badges come from evidence:
-  - _Was there_: a signed capture within N km and M minutes of the event.
-  - _Sealed_: the post has a sealed attachment.
-  - _Local_: the author's home area is set.
-  - _Domain_: pilot, mariner, met, first responder, held as a verified credential.
-
-  Posts are ordered by evidence first, then recency, never by follower count.
-
-- **Community notes with bridging.** Any claim can get a note. A note becomes visible only when raters who usually disagree both rate it helpful (bridging-based ranking, as Community Notes does), which resists brigading.
-- **AI synthesis, kept honest.** A pinned card at the top of every room is labelled **Known / Disputed / Unknown**. AI writes it from the observations and the posts, and every line cites its sources. It is regenerated as the room changes, with its prompt and inputs recorded in the ledger. It never states anything that has no citation.
-- **Live layer.** While you are in a room, presence shows as small avatars, reactions float up the side, and a "N people watching" count appears. Rooms for live situations sit in the feed as Room cards.
-- **Reply with evidence.** "Reply" offers **Capture** first and text second. The best answer to "is the bridge still standing?" is a sealed photo from 200 m away.
-
-### 11.4 Capture: contribute a place, an event, or a live stream
-
-Capture is how a person becomes a sensor. Four modes share one dial:
-
-| Mode        | What it makes                                                                                                                                                                                                         | Trust tier                                                                                                       |
-| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
-| **Look**    | AR overlay of contacts around you. Nothing is recorded unless you tap.                                                                                                                                                | none                                                                                                             |
-| **Witness** | A sealed photo or clip with the IMU, GPS and heading trace (§6).                                                                                                                                                      | **Sealed**                                                                                                       |
-| **Live**    | A broadcast from your camera. It appears on the globe as an _eye_: a frustum cone at your position and heading, with live telemetry, watchable by the room. Every 10 s the stream is sealed as hash-chained segments. | **Sealed live**                                                                                                  |
-| **Upload**  | A photo or video from your library. EXIF is read if present, then you place it on the map and set the time.                                                                                                           | **Unverified**: labelled as such everywhere, and it can never become an observation, only cited by a hypothesis. |
-
-After the shutter comes the **attach sheet**. It suggests the situation you are probably at, from distance and time ("Typhoon Champi · 4.2 km from track", "Times Square camera · 180 m"). It offers "new place" if none fits, a post kind (Witness by default), an optional note, and whether to drop it as a **hologram** that others can find at this spot later. Posting puts the capture in that situation's room, and a Witness card in the feed when it is notable.
-
-Privacy: faces and plates are blurred before upload by on-device detection (a native-build commitment, and a disclosed limitation in the web prototype). Your exact location is shared at the precision you choose (exact, 100 m, 1 km), and the seal still proves the exact value to verifiers without publishing it.

-## 12. Round three: Gotham for everyone
-
-Founder's brief for this round: take what made Palantir Gotham work, fix what Citizen got wrong, and build the window people open every day and the first app they open when something happens. The time slider does far more. Communication feels like Twitch chat meets an X community meets Reddit. Real data wherever possible, more realistic everywhere else. It is demoed on a Mac in Chrome's device mode, as a phone and as a tablet.
-
-> No longer should the audit trail for physical reality be the dominion of nation states. We have the right to know, with the receipts attached.
-
-### 12.1 What we take from Gotham
-
-Gotham's power is not the map. It is that **everything is an object, every object has a history and links, and every view (map, timeline, graph, dossier) shows the same objects**. Select something anywhere and every view follows. Analysts build an investigation, share it, and every fact keeps its source.
-
-| Gotham idea                          | God's Eye version                                                                                                                                                                                        |
-| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| Ontology of objects and links        | **Entities**: aircraft, vessels, satellites, cameras, places, events, captures and contributors (pseudonymous). Each has a **dossier**: identity, live state, track history, events, links and receipts. |
-| Map + timeline + graph, synchronized | Globe, **time machine** and **link graph** share one selection and one clock.                                                                                                                            |
-| Search to dossier                    | Universal search ("N46567", "7700", "Piccadilly", "M5.2", "ISS") opens a dossier, not a list of pins.                                                                                                    |
-| Watchlists and alerts                | **Watch**: follow an entity or a place, and write alert rules in plain chips ("any squawk 7700 within 200 km of Home").                                                                                  |
-| Investigations with provenance       | **Moments**: shareable 4D reconstructions whose every track, capture and claim carries its source and hash.                                                                                              |
-| Audit log                            | The room ledger: every post, note, AI synthesis and vote is hash-chained and exportable.                                                                                                                 |
-
-**The line we don't cross.** Gotham tracks people; we don't. Trackable entities are things that broadcast publicly (transponders, AIS, orbital elements), public infrastructure, and events. Contributors are pseudonymous. There is no face recognition and no person search, and aircraft on owner-privacy lists (LADD/PIA) are never named. This is the product's moral spine and a talking point, not a footnote.
-
-### 12.2 What Citizen got wrong, and our incentives
-
-Citizen grew on fear: an alert stream about crime near you, ranked by alarm, with little verification and a paid "Protect" upsell. Anxiety is the retention loop, rumor travels as fast as truth, and nobody is rewarded for being right.
-
-Ours rewards **being right, early, with receipts**:
-
-- **Signal, not followers.** A contributor's reputation (Signal) rises when their sealed captures are corroborated (cited by others, matched by sensor data such as ADS-B, radar or quakes) and falls when their claims are corrected. Signal weighs their votes and notes. Follower counts are not shown.
-- **First eyes.** The first sealed capture of an event gets a permanent byline on the record ("First eyes: @harbor_cam_kid, 14:02:11Z, 180 m"). This is the reason to open the app and capture when something happens.
-- **Need eyes.** Any room can request coverage at a place ("Is the 7th St bridge underwater?"). People nearby get one quiet ask; fulfilling it with a sealed capture earns Signal and the byline. This turns curiosity into coverage, which is the incentive structure Citizen never had.
-- **Calm by default.** Notifications are severity-gated and local, "Nothing unusual near you" is a valid state, and half the feed is wonder (the ISS overhead, a launch, aurora, a helicopter school) so the daily habit is curiosity, not dread.
-- **Ranking by evidence.** Sealed, corroborated, and close beats loud.
-
-### 12.3 The daily loop
-
-- **Today** (first tab) opens with a brief: "Your world · 7:42 AM": since you last looked (the three biggest changes), what's overhead tonight (ISS pass, launch window), your watched places and things, and **Today's Moment**, one 20-second 4D replay a day worth watching (a ritual, like a daily puzzle). Below the brief comes the situation feed (§11.2).
-- **Your sky now.** One tap shows what is above you this minute: aircraft, satellites, the ISS. This is the most delightful hook in the app.
-- **Watch.** Follow places (home, commute, a family member's city) and things (a tail number, a ship, the ISS). A followed thing's status rides in the tab-bar accessory.
-
-### 12.4 When something happens: Moments
-
-A **Moment** is a 4D reconstruction assembled around an event: tracks, sensor frames, sealed captures with their view cones, the chat, and the record, all on one clock.
-
-- **Detected from real data.** When two or more aircraft circle the same point (news and police helicopters orbiting a scene), the engine raises a situation before any headline: "3 helicopters circling Midtown Manhattan". It also flags an emergency squawk, a cluster of quakes or a sudden lightning cell. These are real detections on live ADS-B and sensor feeds.
-- **Replayable.** Open a Moment and the time machine replays it: helicopter tracks with trails, captures popping in at their timestamps with view cones pointing at the subject, chat replaying at its pace, and posts appearing as they were made.
-- **Hero demo Moment: "Climbers on the Empire State Building".** An illustrative reconstruction with realistic synthetic tracks: two news helicopters and one police helicopter orbiting at 1,000–1,500 ft and radii of 400–700 m, with realistic speeds and turn rates. Witness captures from 34th St, 5th Ave and an office at 1 Penn are shown with their view cones, along with the chat and the record. It is clearly labelled illustrative. It shows exactly what the product does when this happens for real.
-
-### 12.5 The time machine
-
-The time ribbon becomes a time machine:
-
-- **It remembers.** The app records every live contact's position each poll (a ring buffer persisted in IndexedDB, about 6 h). Scrubbing back shows where everything actually was, with ghost trails. A selected aircraft's full track comes from the server's track routes. The app also ships a **bundled real recording** (`mobile/demo/history/`, a few hours over New York, London and the Gulf of Mexico, captured with `capture-history.mjs`) so a first run already has ghosts to replay; it keeps its true timestamps and the time machine shows it where it happened (`RECORDING · <date>`).
-- **Everything moves together.** Contacts, radar and lightning frames, quakes and fires appearing, cyclone positions, the sun, room posts, and captures all follow the clock.
-- **Play.** Play/pause and 1×, 10×, 60× and 600× speeds; momentum scrubbing; detents at events; a **NOW** snap.
-- **Event pips.** Pips from every layer are colour-coded by altitude band. Tapping one jumps to it.
-- **Clip.** Select a range, then "Clip this Moment", which creates a shareable Moment with its receipts.
-
-### 12.6 Talking: Live and Record
-
-Two lanes in every room. This is the delineation that keeps the conversation both fun and true.
-
-|                     | **Live** (Twitch)                                                                                                          | **Record** (Reddit and X)                                   |

-| Reactions           | Hearts, 🔥, 👀 and 😮 fly up the screen, **and rise from the reactor's location on the globe**: you see the world watching | Corroborate / Dispute votes weighted by Signal              |
-| Badges              | Witness glow for people with a sealed capture nearby, plus First eyes                                                      | Was there, Sealed, Local, Domain                            |
-| Becomes the record? | Only if it carries evidence or is promoted by corroboration                                                                | Yes, hash-chained in the ledger                             |
-
-- **The clerk.** Every few minutes, AI summarizes the Live lane into "What chat is saying", with citations to messages, and posts it into the Record as a clearly labelled synthesis.
-- **Crews.** Crews are persistent groups (X communities): "NYC Scanner Nerds", "Fort Novosel Alumni", "Gulf Storm Chasers". A crew has its own feed, members and rooms, and can co-watch a Moment together.
-- **Watch parties.** Opening a live situation drops you into its Live lane, with presence and the heart stream. That is the "hearts flying" feeling, everywhere.

-### 12.8 Demo mode
-
-The demo is presented in Chrome's device toolbar on a Mac:
-
-- **Instant first frame.** The last good situations and thumbnails are cached (IndexedDB) and a bundled snapshot of real data ships with the app (`mobile/demo/`, with its capture time shown). The app paints in under a second, then hydrates live.
-- **Mouse and touch** work everywhere (drag sheets, scrub, pinch with trackpad).
-- **Director.** Press `.` (or triple-tap the logo) to open a presenter menu that jumps to the beats of the story: Today → Your sky now → the Empire State Moment → the Live lane with hearts → Need eyes → Capture → Dossier and link graph → the time machine → tablet layout. Each beat sets up its state so the demo never depends on luck.
-- **Honest labels.** Real data shows its source and age. Illustrative content (the hero Moment, simulated chat, example posts and crews) carries a small "Illustrative" or "Simulated" tag. A VC should see that the real parts are real.

-
-The `thumbnail` field is still a plain Esri still, so older code keeps working. New code calls `globe.thumbnail(situation)` instead.
-
-The engine orders the cards by severity, then interleaves them so neighbouring cards differ in band and archetype where possible.
-
-## Card compositor
-
-```js
-globe.thumbnail(situation, { width = 360, height = 480, dpr = 2 } = {}) → Promise<string /* blob: object URL */>
-```
-
-The compositor builds each thumbnail as a JPEG in an offscreen 2D canvas, never in the Cesium viewer. It works in three layers:
-
-1. **Base imagery.** Esri World Imagery tiles, which are CORS-clean, or NASA GIBS Black Marble for orbit cards.
-2. **Real overlays.** The data that describes the situation. Examples include NOAA IR with a cold-top enhancement, MRMS radar, lightning density dots by age, the NHC cone with the forecast track and 34/50/64-kt wind radii, aircraft with 2-minute velocity leaders, quake rings, fires with a smoke plume along the observed wind, and SGP4 ground tracks.
-3. **Grade.** A tint for the altitude band (orbit violet night, sky cool, ground amber) and a vignette.
-
-The compositor draws no text and no brackets.
-
-Eye cards return the camera frame itself, lightly graded. Results are cached in memory and, when the page is a secure context, in the Cache API, keyed by id, size and an update bucket. Eye cards refresh every 30 s; other cards follow `updatedAt` in 5-minute buckets. Tiles are shared across cards, and at most 3 cards render at once.
-
-If an overlay fails, the card still gets its base picture. The promise rejects only when the base imagery or the camera frame fails. In that case, fall back to `situation.thumbnail` or to the shell's own placeholder.
-
-## Pins (discourse and capture)
-
-```js
-globe.addPin({ id, lon, lat, kind, headingDeg?, fovDeg = 60, rangeM = 350, color?, label?, altM? }) → id
-  // kind: 'post' | 'witness' | 'eye' | 'live' | 'hologram'
-  // 'live' and 'eye' pins draw a view-frustum wedge on the ground along headingDeg
-globe.removePin(id) → boolean
-globe.pins() → [{ id, lon, lat, kind, headingDeg, fovDeg, rangeM, color, label, altM }]
-```
-
-- Picking a pin emits `'pick'` with `{ kind: 'pin', pinKind, id, title, subtitle, lon, lat, meta: { layer: 'pins', headingDeg, fovDeg, label } }`.
-- Pins appear in `globe.labels()` with `layer: 'pins'` and `pinKind`.
-- Live pins breathe at 1 Hz.
-
-## Labels
-
-Each entry from `globe.labels(max)` can now carry an optional `detail`, a short intensity tag:
-
-- Cyclones: `CAT 2 · 85 KT · 974 HPA`
-- Emergency squawks: `SQ 7700`
-- Air quality: `AQI 152`
-
-## Nearest public camera
-
-```js
-globe.nearestEye(lon, lat, km = 50)
-  → Promise<{ id, title, lon, lat, distanceKm, headingDeg, fovDeg, imageUrl, city, provider } | null>
-globe.eyeFrameUrl(cameraId) → string | null   // a fresh same-origin frame URL
-```
-
-`nearestEye` reads the CCTV catalog at `/api/cctv/sources`, which serves about 4,000 cameras across London, Toronto, Sydney, Seattle, the Bay Area, Los Angeles, Helsinki/Finland, Tallinn, Barcelona, Calgary, Norway and other places. It does not check the frame. A camera can still answer with the proxy's synthetic image when its upstream is down.

-
-Rasters are drawn a few kilometres above the ground and unlit, so storms stay visible on the night side. When an upstream is down, the layer reports `status: 'error'` with a `message`.
-
-When a weather layer is on, `layers()` entries can also carry `frames` (the number of frames available) and a `message` that gives the product title and the frame age.
-
-When NHC has published an advisory but its cone geometry is still pending, the cyclone layer and cards take the forecast positions from the advisory text, so a track is still drawn but there is no cone.
-
-## Dev harnesses
-
-- `mobile/globe/dev.html` shows the globe full-screen and exposes `window.globe`. Its labels show `detail`.
-- `mobile/globe/contact.html` is the contact sheet: it calls `situations()`, then `thumbnail()` for every card.
-  - `?lat=&lon=` sets the viewer.
-  - `?only=cyclone,eye` filters cards by id prefix.
-  - `?w=330` sets the card width.

-# Round three: Gotham for everyone (DESIGN.md §12)
-
-Additive. Nothing above changes. Every call below exists on the object `createGlobe()` resolves to. Times are epoch ms unless a `Date` is shown.
-
-## Instant first frame
-
-```js
-globe.situations({ cached: true }) → Promise<Situation[]>
-  // resolves at once from the last good IndexedDB snapshot (written by every live
-  // situations() call), else the bundled mobile/demo/snapshot.json (real data).
-  // Each cached Situation adds: cached: true, cacheOrigin: 'device' | 'bundled',
-  // capturedAt (epoch ms), live: false, thumbUrl (bundled /mobile/demo/thumbs/<id>.jpg
-  // or a Cache API blob URL) or null.
-globe.situations()                → Promise<Situation[]>   // live, as before (also saves the cache)
-globe.cachedThumbnail(situation)  → string | null           // sync; thumbUrl for a cached card
-globe.thumbnail(cachedSituation)  → resolves to the cached JPEG when the card has no live scene
-```
-
-The globe paints its first frame with imagery only. Live layers start right after it, and weather, transit, GNSS, Starlink and satellites start about a second later. Background warm-ups (jet, TCM, AQ, CCTV, rasters) start at 4 s.
-
-## Recorder and time machine
-
-```js
-globe.history() → { start, end, entities, points, bytes }   // recorded range; start/end null when empty
-globe.setTime(t)   // unchanged. Inside the recorded range, contacts are drawn at their interpolated
-                   // recorded positions with 4-minute ghost trails (pickable: 'pick' kind is the
-                   // contact's kind, meta.layer 'history', entityId). Beyond the record, dimmed as before.
-globe.trackOf(entityId) → Promise<[{ t, lon, lat, altM, headingDeg, speed }]>
-                   // recorder samples merged with /api/flights/track (OpenSky) or /api/military/track
-                   // (adsb.lol traces); the array has .source
-
-globe.playback.play({ speed = 60, from?, until? } = {}) → state
-  // speeds: 1, 10, 30, 60, 600. From live it replays the last 15 min. Reaching "now" goes live;
-  // inside a Moment it stops at the Moment's end.
-globe.playback.stop() → state
-globe.playback.state() → { playing, speed, t, live }
-globe.playback.speeds  // [1, 10, 30, 60, 600]
-  // event 'playback' → state, on start/stop and every 250 ms while playing.
-  // 'time' is also emitted every 250 ms while playing ({ live:false, time, playing:true }).
-  // Playing runs the render loop; at rest the globe is request-render again.
-
-globe.timeline({ from, to } = {}) → [{ t, kind, band, title, severity, situationId?, entityId?, momentId?, lon?, lat? }]
-  // kind: 'quake' | 'quake-cluster' | 'launch' | 'squawk' | 'cyclone' | 'fire' | 'circling'
-  //       | 'lightning' | 'moment' (a Moment beat) | 'capture' | 'post' | 'chat-burst'
-  // band: 'orbit' | 'sky' | 'ground' | 'inside'; severity 0..3; sorted by t.
-  // Defaults to timeWindow(). Moment items appear for Moments that were loaded and overlap the range.
-```
-
-The recorder keeps every poll for low traffic (helicopters, approaches, anything below about 6 km) and one fix every 50 s for cruise traffic. Samples older than 30 min are thinned. The buffer is capped at 1.2 M samples (about 24 MB) and persisted to IndexedDB about once a minute, so a reload keeps up to 6 h. When OpenSky is down, the recorder also polls adsb.lol snapshots around New York, London, Los Angeles and the viewer every 15 s, so the detector has real data.
-
-Entity ids are layer-qualified: `flights:<icao24>`, `military:<hex>`, `satellites:<norad>`, `earthquakes:<id>`, `cctv:<id>`, `vessels:<mmsi>`, `situation:<id>`, `place:<slug>`, `moment:<momentId>`, `moment:<momentId>:<trackId>`, `capture:<momentId>:<captureId>`. Every `'pick'` payload can be passed to `entity()` as is.
-
-## Detection
-
-Detections run on recorder data every poll. They appear only when real data shows them.
-
-- `circling`: two or more aircraft (rotorcraft and low-and-slow preferred, below about 8,000 ft and 155 kt), each turning through at least 360° within about 1.5 km of a common centre in the last 20 min. Card: `{ kind:'circling', band:'sky', archetype:'track', title:'3 helicopters circling Midtown Manhattan', momentId:'live-circling-…', members:[{ key, layer, callsign, helicopter }], entityIds, detected:true }`. Its thumbnail draws the recorded orbit tracks. A single aircraft on its second full orbit is a lesser detection (severity 4.5, `single: true`, for example "Helicopter circling Las Vegas Strip"). `momentOfTheDay()` ignores single orbits.
-- `quake-cluster`: three or more M2.5+ earthquakes within 50 km in 24 h. Archetype `number`, with a magnitude series.
-- `squawk` cards now carry `momentId: 'live-squawk-<icao24>'`.
-
-```js
-globe.detections() → Situation[]    // current detections, sync
-// event 'detections' → detector output, when the set of circling detections changes
-```
-
-## Moments
-
-```js
-globe.moments() → Promise<Moment[]>      // live (circling, squawks) first, then the bundled hero
-globe.moment(id) → Promise<Moment|null>  // 'empire-state' | 'live-circling-…' | 'live-squawk-<hex>'
-globe.momentOfTheDay() → Promise<Moment> // best live Moment if any, else the hero
-globe.playMoment(idOrMoment, { speed, camera = true, autoplay = true, framing = 6 } = {}) → Promise<Moment>
-  // speed defaults to moment.recommendedSpeed (hero: 30 → 50 s). camera:false leaves the camera alone.
-  // framing: degrees the cinematic camera looks below the subject (puts it in the upper half).
-  // Hides every live layer, draws tracks (glyph, 90 s bright trail, faint flown path, drop line),
-  // capture view frustums that pop in at their t, the subject building and its beacon, and flies
-  // the camera path keyed to the clock. Touching the globe releases the camera.
-globe.exitMoment({ restoreCamera = true } = {})   // back to live (or the time before) and the old camera
-globe.activeMoment() → { id, title, illustrative, t, start, end, playing, speed, cinematic, moment } | null
-globe.seekMoment(t)            // epoch ms, or a 0..1 fraction of the Moment
-globe.momentCamera(on = true)  // re-attach (or release) the cinematic camera → boolean
-// event 'moment' → { type, item, t, momentId }
-//   type: 'start' (item = Moment) | 'capture' | 'chat' | 'post' | 'beat' | 'end' | 'exit'
-//         | 'camera' (item = { cinematic:false } when the person takes the camera)
-//   Items fire as the clock passes them while playing, and on small seeks. A seek back, or a jump of
-//   more than 90 s while paused, repositions silently: render the Live/Record lanes by filtering
-//   activeMoment().moment.chat/posts/captures by t <= activeMoment().t.
-```
-
-```ts
-Moment = {
-  id, title, place, lon, lat,
-  time: { start, end },                 // epoch ms
-  illustrative: boolean,                // true for the bundled hero; false for live detections

-```
-
-`playMoment`, `exitMoment` and `setTime(null)` are safe to call at any time, including mid-playback or while a load is still pending: a later call supersedes an earlier one, and the stage frees its primitives only after the frame in progress.
-
-`labels()` collision-avoids each label as it will be drawn (`title · detail`). When a Moment label collides, it falls back to callsign plus altitude, then to the callsign alone. Such entries carry `abbreviated: true` and the shortened `title` and `detail`.
-
-The hero is `mobile/demo/moments/empire-state.json` (id `empire-state`): "Climbers on the Empire State Building", 25 min, 3 helicopters, 8 captures, 120 chat lines and 12 posts. Regenerate it with `node mobile/demo/build-empire-state.mjs`. Its Midtown massing is real NYC Open Data footprints and roof heights in `mobile/demo/midtown-buildings.json` (`node mobile/demo/build-midtown.mjs`). Its river surfaces are OpenStreetMap water polygons in `mobile/demo/midtown-water.json` (`node mobile/demo/build-midtown-water.mjs`). They are drawn over Esri's mismatched water mosaic across the Hudson.

-Kinds: `aircraft`, `helicopter`, `military`, `satellite`, `vessel`, `quake`, `camera`, `situation`, `place`, `moment`, `track`, `capture`. There are never person entities. Aircraft dossiers wait at most 2.5 s for the server track (aircraft identity comes from adsbdb, 3.5 s budget).
-
-## Reactions and attention
-
-```js
-globe.react({ lon, lat, kind: 'heart'|'fire'|'eyes'|'wow', count = 1, altM = 0 }) → number
-globe.attentionHeat(points | null)    // points: [{ lon, lat, weight? }]; soft glow where viewers are
-```
-
-Reactions draw on a screen-space canvas that the globe owns (`.gev-reactions`, pointer-events none, above the globe and below your HTML). Each glyph stays anchored to its point as the globe moves. At most 300 are alive at once, and the canvas animates only while some are alive.
-
-## Your sky now
-
-```js
-globe.skyNow({ lon, lat } = viewer) → Promise<{
-  at, observer, sunElevationDeg,
-  aircraft:   [{ id, title, kind, lon, lat, altM, distanceKm, elevationDeg, azimuthDeg, headingDeg, speedMps, squawk }],
-  satellites: [{ id, title, norad, altKm, elevationDeg, azimuthDeg }],
-  iss: { visibleNow, aboveHorizon, elevationDeg, azimuthDeg,
-         nextPass: { start, max, end, maxElevationDeg, riseAzimuthDeg, visible } | null },
-  sources: [string],
-}>   // aircraft within 50 km, satellites above the horizon; each list sorted by elevation, highest first
-```
-
-## Dev harness
-
-`mobile/globe/dev.html?moment=empire-state&speed=30` plays a Moment on load and prints its events in the HUD. `globe.debug` exposes `{ recorder, detector, stage, ghosts }` for tests. It is not part of the contract.
-
----
-
-# Polish round
-
-Additive. Nothing above changes.
-
-## Bundled recording (the time machine always has ghosts)
-
-`mobile/demo/history/{nyc,london,gulf}.json` hold a real recording of every aircraft over the New York area, London and the North Sea approaches, and the Gulf of Mexico, captured by `node mobile/demo/capture-history.mjs` (adsb.lol point snapshots around each region's anchors, the dev server's `/api/flights` and `/api/military` as fallbacks; one fix per 30 s below 6 km, per 120 s in cruise). Positions are quantised to 1e-4° and 10 m and delta-encoded (`format: 'gev-history/1'`). Timestamps are the true capture times and are **never shifted**: the time machine shows the recording where it happened.
-
-The engine loads it about 5 s after the first frame into a second recorder (no expiry) and reads both through one view: ghosts, `setTime` history mode, `entity()`, `trackOf()` and `search()` see the recording; on a key present in both, the device's own recorder wins.
-
-```js
-globe.history().archive → { start, end, regions: [{ id, label, bbox, source, start, end, tracks,
-                            busiest: { t, aircraft } }] } | null
-globe.loadHistory()     → Promise<history().archive>          // resolves once it is loaded
-globe.historyNear(t, lon, lat, km = 100)
-  → [{ id /* entity id */, key, kind, title, lon, lat, altM }]  // recorded contacts at t, nearest first
-// event 'history' → history(), once the recording is loaded
-```
-
-The time ribbon shades the recording in teal (`RECORDING · 23 OCT`) next to the device's own `RECORDED` range, and its readout names the day when the playhead is on another UTC day.
-
-## Camera
-
-```js
-globe.flyTo({ lon, lat, height, heading, pitch, eye: true }); // eye: lon/lat/height place the camera itself
-```
-
-## Night close-ups
-
-Below ~400 km, where Cesium's lighting is faded out, a night-side view grades the Esri mosaic toward night (darker, desaturated, slightly cooler) with a soft glow of the real Black Marble lights above ~40 km; the strength follows the sun's elevation under the camera at the **scene clock**, so a Moment keeps the lighting of its own time (the hero is daylight). A terrain watchdog falls back to the flat ellipsoid when the keyless terrain host stalls (the globe would otherwise show only the star field).
-
-## Dossiers
-
-`privacy` is set only for real privacy programmes (`'pia'`, `'ladd'` flags). An airframe with no public registry record gets `registryMissing: true` instead, and `identity.operator` falls back to the callsign's ICAO airline prefix (`mobile/globe/airlines.js`, about 150 operators).
