Merge branch 'main' into codex/fix-tool-display-text

Read OpenSky OAuth credentials from OPENSKY_CREDENTIALS_FILE and stop sending retired Basic authentication. Update setup diagnostics and guidance.

Keep credential-file warnings free of parser excerpts and filesystem error details, cover both failure paths with a regression test, and use a launcher-compatible absolute path example.

   **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.
+- **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).

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.
 - **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All sixteen registered regions are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. 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.
 - **Re:Earth Terrain.** Keyless (no API key). Used two ways: (1) `src/mapStackController.js` swaps in a `Cesium.CesiumTerrainProvider` pointed at Re:Earth's `cesium-mesh/ellipsoid` quantized-mesh endpoint for globe stacks without a Cesium ion token (e.g. OSM), replacing a flat `EllipsoidTerrainProvider`; falls back to the flat provider if the endpoint can't be reached.

+The standalone app offers **OpenAI** and **Gemini** in the GEV MIC provider chooser. OpenAI is the initial default; your choice is saved in this browser. To use Gemini, add `GEMINI_API_KEY` in Provider Settings or your local `.env` file, then select Gemini. `GEMINI_LIVE_MODEL` defaults to `gemini-3.8-live`. The permanent key stays on the local server, which issues a constrained, single-use session credential.
+
+Changing provider ends the current conversation. If voice is on, the new provider starts with the same open-mic or push-to-talk mode; a held Space key is not carried over. Gemini uses the same map actions and captions, but has no OpenAI cost meter or MINI tier. When Gemini reports that its session has expired, start voice again for a new conversation. The provider chooser does not change the OpenAI-backed AI HUD summary.
+
 > Voice can use an **OpenAI API key** or, on the same machine, an opt-in signed-in **ChatGPT/Codex OAuth** session. The API-key path remains the default. Selecting ChatGPT OAuth in Provider Settings reuses an existing local sign-in or starts the Codex browser sign-in flow and selects OAuth when it completes. The OpenAI key still drives the **AI HUD summary**: a terse, five-word intelligence-style readout of the current view that regenerates as you move.
 
 The OAuth option is experimental. OpenAI documents ChatGPT plan usage for the [Responses API](https://developers.openai.com/siwc/token-sharing-open-source/models-and-inference); a supported third-party Realtime contract for reusing Codex tokens has not been confirmed.

 1. **Google Maps API key** — loads Photorealistic 3D Tiles directly and powers Street View (Maps JavaScript API; add it to the key's API restrictions). **Restrict it** (HTTP referrer + API restriction to the required Google APIs) in the Google Cloud Console. An unrestricted key in a public deployment can be abused and billed to you. Restrict it to the **Map Tiles API and Maps JavaScript API only**: a referrer restriction applies to the Maps JavaScript API and the client SDKs, not to the web services, so a key carrying Geocoding under one is refused with `API keys with referer restrictions cannot be used with this API`. Search does not need it — geocoding goes through the server proxies above (#363).

 - **No verbatim client headers upstream.** The CCTV media route is the one route that relays a request header (`Range`, for video seeking). It is parsed and canonicalized before it is forwarded: one `bytes=` range only, with every accepted form — explicit span, open-ended and suffix — bounded to the same 64 MiB ceiling the relay applies to a declared response body. Multi-range, malformed, inverted and non-`bytes` values are dropped and the request proceeds without a `Range`, as RFC 7233 §3.1 prescribes. Bounding the request bounds what is asked for: a response that declares no length — live streamed media, or a chunked body from an upstream that ignores the `Range` — has no ceiling. An upstream request the browser has stopped waiting for is cancelled rather than left running, whether the viewer leaves before the headers arrive or during the body.
 - **Transit fetches registered feeds only.** `/api/transit/vehicles/<id>` resolves the id against `src/data/transitFeeds.js`; the browser never supplies a URL, and a feed that is registered but disabled does not resolve at all. Redirects are followed manually and each hop is validated against the feed's own https origin before it is requested, so an off-origin or downgraded hop is refused rather than contacted. Bodies are capped at 8 MB, the protobuf is decoded server-side under entity-count and string-length ceilings, a differential feed is refused, and snapshots live 15 s in memory with no disk cache. A per-feed admission limiter and a failure cooldown ladder bound what this process can ask of any operator.
 - **Local receiver feeds are operator-configured and local-only.** `/api/local-receivers/aircraft` reads only the `aircraft.json` URLs in the server's `LOCAL_RECEIVER_FEEDS`; the browser never supplies an address. Each host must pass the shared tap address rule (`src/data/tapAddress.js`: loopback, RFC1918, `localhost`, `*.local`; no link-local, IPv6 or other names), the scheme must be http(s), the path must end in `aircraft.json`, and credentials, queries and fragments are refused. Invalid entries are logged at startup and never fetched. Reads use a 2 s timeout, refuse redirects, cap bodies at 2 MB and share one read per second; responses name each feed by band only and never carry upstream error text.
+- **Validated response formats.** Proxied bodies are relayed only in the format the route serves. CCTV frames and the Street View fallback accept JPEG, PNG, GIF, WebP and AVIF only, sent under their canonical type; any other type falls through to the next fallback. Live CCTV media must match its feed kind (`video/mp4`, `video/webm`, or `multipart/x-mixed-replace` with a boundary) before it is relayed or the camera counts as healthy, and its redirects stay on the registered origin. GBFS bodies must parse as JSON and are re-serialized as `application/json; charset=utf-8`. Camera catalog URLs are pinned by parsed URL — scheme, exact host, no credentials, default port, and a normalized path inside the agency's image directory — and a redirect on a pinned host must stay inside the same directory. Every `/api/cctv` route uses the keyless cross-site checks described below, so cameras stay reachable behind a reverse proxy; a request carrying forwarding headers never reaches the key-bearing Street View fallback and gets the placeholder frame instead, as when no key is configured.
+- **Consistent API response headers.** Every `/api` response, including errors, partial content, Host refusals and unknown routes, carries `Content-Security-Policy: default-src 'none'; sandbox` and `X-Content-Type-Options: nosniff` (`apiResponseHeadersPlugin` in `build/vite.js`, installed ahead of the Host check). A route that sets its own policy adds it as a further policy; it never replaces this one.
 - **Response-size caps and timeouts** on proxied responses.
 - **Sanitized errors** — internal error details are not echoed back to clients.
 - **Coalesced OAuth refresh** and cached successful responses only (OpenSky).
 - **Redacted debug logging.** The voice debug log (`.gev-logs/`, gitignored) strips API keys, bearer tokens, client secrets, and image data URLs before writing.
-- **Cross-site gate on cost/log endpoints.** The cost-bearing (`/api/realtime/token`, `/api/openai/hud-summary`, `/api/google/nearby-places`, `/api/google/text-search`), quota-bearing (`/api/mapillary/*`, with a per-IP limit on tiles, and `/api/tomtom/*`, backed by its persistent daily tile budget) and log (`/api/realtime/debug-log`) endpoints refuse cross-site browser requests: a foreign or opaque `Origin`, a `Sec-Fetch-Site` other than `same-origin`/`none` (this is what blocks an `<img>`/navigation that carries no `Origin`), or any reverse-proxy/CDN forwarding header returns `403`. Non-browser loopback tools (the repo QA harnesses POST the token endpoint with no `Origin`) and the explicit `HOST=0.0.0.0` LAN opt-in keep working — the gate deliberately does not require a loopback remote address; that stricter requirement belongs only to the credential panel (`admitKeySetupRequest`). The Host check (`allowedHosts`, applied by `hostCheckPlugin` ahead of every route, since Vite's own check runs only after plugin middleware) rejects a rebinding `Host` before any handler runs, in every mode, and the gate is defense in depth behind it: the LAN opt-in keeps that check and accepts only IP addresses, `localhost` and names listed in `GEV_ALLOWED_HOSTS`. **Limit:** a name you list there is trusted like the app's own address, so list only names you control.

The keyless terrain route (`/api/terrain/heights`) uses the same cross-site checks, minus the forwarding-header refusal: it guards only the per-client quota and point cache, not a key or a bill, and the map needs it to render behind a reverse proxy. The CCTV routes (`/api/cctv/*`) use the same keyless checks; their one key-bearing step, the Street View fallback, is skipped for any request with forwarding headers.
 - **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.

+## Segmented selectors
+
+Segmented selectors use the controlled DOM adapter in `ui/segmentedControl.js`
+and the shared `gev-segmented` / `gev-segment` surface. Model coverage, label
+allocation, drawing shape, Street View fit/panorama filters and imagery mode keep
+their feature-owned values, actions and persistence. Painting a restored value
+does not emit a change or move focus. Existing keyboard policies remain explicit:
+Street View uses arrows/Home/End with one tab stop, imagery mode uses arrows from
+its controlled selection, and Display keeps its existing native button behavior.
+Pure value navigation is separate from DOM rendering for reuse by a future view.
+Segments keep their word minimum width: compact inline groups such as FIT/FILL
+and ALL/360°/FLAT must not break short labels mid-word. Collapsed Weather follows
+the same exclusive-rail hiding rule as the other readouts.
+The imagery mode row reserves 26px for the 24px buttons and group borders so
+the complete button and inset keyboard-focus outline remain visible.

+## Phone layout
+
+At 720px and narrower, `src/ui/mobileShell.js` keeps the globe full screen and
+shows a bottom tab bar: Layers (Data Layers, with Scenes collapsed below),
+Cameras (CCTV and Street Level), Context (Global Context, plus Weather and
+Recent Imagery when shown), Search (Location) and More (Visual Presets and Map
+Source above Display). A tab opens one bottom sheet; the same tab, the backdrop
+or Escape closes it, and focus moves into the sheet and back to its tab. A
+downward swipe of at least 64px on non-control sheet content also closes it,
+when every scroll container under the finger starts at the top. Ordinary
+vertical scrolling, horizontal gestures, controls and multitouch stay native;
+a cancelled gesture or a sheet/viewport change cannot dismiss another sheet. Panels
+are not moved in the DOM: `styles/mobile-shell.css` presents the rails and dock
+as the sheet, and the dock's Location and Presets trays render inline. The voice
+control floats above the tab bar while no sheet is open.
+
+The phone logo is 58px wide (about 39px high), aligned with the top controls.
+The shared contact picker preserves exact picks. For a coarse primary pointer
+that misses onto the map surface, it searches at most eight hits in a 14px square
+and accepts the first registered layer hit, stopping at non-map objects. Civil
+and military aircraft and vessels share this rule; fine pointers stay exact.
+
+Manually opening Context with a tracked civilian or military aircraft enters
+the existing Contacts mode when Context is off. Contacts adopts that aircraft
+without restarting its tracking; an active or entering Space Missions mode is
+left alone. Programmatic sheet changes and closing the tab do not activate a mode.
+
+Sheets borrow panels. Opening one expands its panels without persisting them or
+claiming a user choice, and share links keep reporting each borrowed panel's
+state from before the sheet; closing puts back what opening changed, while a
+panel the user changed inside the sheet stays as they left it. Escape closes the
+sheet before a panel's own Escape handling, and the dock's hover auto-close does
+not apply inside a sheet.
+Cockpit, recording and clean view close the sheet and hide the tab bar; scene
+playback keeps both so its STOP control in the Scenes panel stays reachable. The
+right rail neither hides collapsed siblings nor applies Cyber's one-panel
+accordion at these widths, since the sheet chooses what shows. The Cesium and Google attribution stays visible above the
+voice control, and above an open sheet. The page draws under the notch and
+system bars (`viewport-fit=cover`) and the shell's chrome uses safe-area insets.

Focus establishes a launch-site-centered camera transform once; subsequent manual heading and pitch changes remain centered on that site without an automated per-frame correction. Surface mission markers and labels use an additional conservative globe-limb margin before the exact ellipsoid occluder boundary, preventing near-horizon visibility from alternating between frames.

+- **Camera verbs** (`src/cameraVerbs.js`) — one motion slot, driven per clock tick. `move_camera` orbits/pans/tilts/rotates; `fly_route` is a cinematic dolly along an existing route annotation. `rotate_globe` rotates the world-space camera rigidly around Earth's center using its screen-up axis, preserving geocentric range and framing. Left/right describe visible globe motion, while `rotate` turns the camera in place. Omitted globe direction/mode default to right/continuous; explicit values prevail. Other camera motions keep their once default. Admission requires 3D, no Cockpit/tracking owner and the whole globe inside the existing keyhole circle, using the shared keyhole/projection geometry and vertical camera FOV with a rotation-local bounding-sphere cone for off-axis containment. Canvas-edge clipping alone does not block a rigid rotation or its unchanged Globe View preset. There is no altitude cutoff. An already smaller, fully framed globe rotates directly; repeated nudges, direction and speed changes recheck current framing without demanding a reset merely because ellipsoid altitude varied. A close-up or overlap refuses without moving the camera. When the unchanged Globe View preset fits, voice says “Globe rotation isn’t available from this view. You can say ‘Reset to Globe View and rotate the globe.’” without asking a permission question or automatically resetting. Explicit Reset/Show Globe View commands remain direct; an explicit reset-and-rotate request waits for reset success before requesting rotation. If OpenAI dispatches both tools together, rotation waits for earlier same-response resets and is skipped if any fails or is cancelled. OpenAI rejects later tool calls in the same response after a globe refusal, including calls arriving while globe admission is pending, and preserves response-scoped `tool_choice: none` for the refusal follow-up; Gemini rejects further tool execution, including queued sibling calls, until fresh typed input or admitted speech. Model interruption, advisory captions and microphone toggles do not release that guard. There is no pending Yes/No offer. Outside the refused response, explicit-command interpretation and avoiding repeated resets remain model-guided; a distinct model-issued reset call is not an app-enforced proof of user intent. A failed standalone reset can still be retried by the model, and a reset result does not guarantee the camera has fully settled. Before suggesting a reset, a cloned camera checks the unchanged Globe View destination against the same keyhole/depth rules without moving the live camera. If that preset cannot fit, `globe-reset-unavailable` asks for further zoom and the refusal instructs further zoom instead of a reset; this also covers ultrawide views. Unsupported view geometry or non-WGS84 projection assumptions fail closed without the closer-zoom instruction. Supported camera inputs/navigation intents cancel rotation before their action. Finite radius greater than the ellipsoid's maximum radius proves whole-arc clearance at constant centre-distance; no low-altitude swept solver is needed. The unchanged Globe View reset preset remains 18,000,000 m. Terrain and buildings remain outside the guarantee.
   - **The route dolly is shaped, not linear** (2026-08-20). A trapezoid speed profile (smoothstep up, cruise, smoothstep down, distance taken as the closed-form integral) eases both ends without changing the pace — duration is still `totalM / ROUTE_M_S[speed]`, with one exception: a 0.5 s minimum keeps a degenerate route from being an instant teleport, so routes under 10 m (slow) / 20 m (normal) / 45 m (fast) fly SLOWER than the speed word, never faster. Turns bank up to **10°** (a 90° street corner settles near 7.5°), measured as a triangular pulse over a 4 s window centred on the camera so the roll leads in and unwinds after. Altitude breathes ±20 m around the 260 m mean and lifts up to 26 m into turns. Pitch is LOCKED at −32°; heading comes from a gaze that leads the path by 6.5 s of travel. `prefers-reduced-motion` zeroes the roll and the altitude shaping and keeps the easing.
   - **Invariants — do not "fix" these.** (1) **Every** release levels the roll: completion unwinds it through the ease-out envelope, and `interruptCameraMotion` zeroes it synchronously (heading/pitch/position preserved). Cesium keeps the last up vector it was handed, so skipping this leaves the user holding a tilted horizon. (2) Heading is interpolated as an ANGLE about the local up, never as a Cartesian lerp — a lerp cannot cross an antipodal pair, so an out-and-back route looked backwards for the entire return leg; `signedTurnRad` branches the exact-180° case deterministically because the cross product's sign there is a floating-point coin toss. (3) A COLD floor cell is missing data, not flat ground: route vertices carry height 0, so trusting them flew a mountain corridor at 260 m above the ELLIPSOID. The corridor warm is fire-and-forget, so the dolly ARMS — camera untouched, no teleport onto the route — for up to 1.2 s waiting for real floor data, falls back to a rendered-mesh probe (`scene.sampleHeight`) when the DEM stays cold — latched to ONE firing per flight, for exactly the cells the cache could not answer, so a route costs at most 8 `sampleHeight` calls however long it arms — and otherwise holds the launch altitude for the whole route. A corridor is only RESOLVED when every cell is accounted for: one warm cell says nothing about the ground under the other seven, and treating it as an answer let the dolly descend to 460 m over a 1,600 m rendered surface. The probe reads the rendered surface at the current LOD (rooftops and primitives included) — a better estimate than nothing, not a guaranteed upper bound. Never descend blind. The floor is SMOOTHED in both directions for the ride while the hard clearance clamp reads the RAW sample, so a cell boundary cannot pop the eye but a cliff is still cleared on the frame it is seen. A pre-departure floor is adopted whole; one arriving mid-flight is eased onto, and the eye's descent rate is capped.

   - **Subject reconciliation across satellite catalog rebuilds** (2026-08-21). A dense↔core toggle or TLE refresh clears and repopulates the catalog, so the published subject is re-resolved against the new satrec; a subject that did NOT survive releases the slot. The per-frame refresh cannot do this itself — `_getTrackedFramePosition` returns early once the satellite has no catalog entry — so the reconcile runs at rebuild completion. An empty catalog is a rebuild in flight, not a disappearance.

 - **Grounded 3D handoff is terrain-validity gated (2026-08-23).** A ready civilian or military glTF does not own the visual until `groundSnap` (`src/data/groundSnap.js`) can answer with a MEASURED photoreal-surface height. On success the layer writes `height + the model's measured belly offset` before revealing the model. Cache movement is measured on the WGS84 surface, not across altitude, so a stationary contact keeps its snap through poll-time vertical-datum changes. Model existence or GPU readiness alone never suppresses the billboard floor, and ordinary zoom/style/deselect transitions preserve a valid snap cache. **Two states, and the difference is the whole design.** COLD — nothing has ever resolved for this icao (tiles still streaming on first sight, sample failure, backoff after a first miss): there is no evidence of where the ground is, `heightFor` returns null, the model stays hidden and the depth-test-free 2D billboard remains opaque and floored. WARM — a snap resolved and then a >`MOVE_INVALIDATE_M` (50 m) taxi move stopped it answering directly: the measurement is DEMOTED to a bounded last-known rather than deleted, and it keeps answering while the resample is outstanding, so a taxiing aircraft does not pop 3D→2D→3D across a 2–30 s retry backoff. The bound is `HELD_SNAP_MAX_DRIFT_M` = 250 m from the spot the value was measured at, past which the hold is dropped rather than stretched and the contact is COLD again. It is spatial with no timer beside it (ground under a contact that has not moved does not change; what invalidates the value is the contact MOVING) and deliberately a quarter of the billboard chain's `HELD_FLOOR_MAX_DRIFT_KM` — that hold only ever RAISES a sprite, while a held snap IS the model's placement, so its error shows in both directions. A fresh sample releases the hold, and so does a ground flip (which already calls `forget`). **A loading model is HIDDEN, never zero-scaled:** admission sets `show = false` (Cesium's default is `true`, and an unplaced primitive would claim the visual at the identity matrix), and ownership is `ready && show` — Cesium 1.138's `Model.update` has no `show` guard, so hiding a primitive costs its load nothing.
 - Commercial and military aircraft use the same high-level FLEET model regime: 2D billboards when zoomed out, optional glTF models when closer, controlled by the DISPLAY rail `3D` toggle and `Proximity` / `All` modes. Since 2026-08-16 (Hangar fleet) models are PER-CLASS: real CC-BY GLBs for light/bizjet/turboprop/widebody/helicopter/uav (`CLASS_MODEL_REAL` in `src/data/aircraftClass.js` — meters-baked, scale 1, per-model belly/radius; provenance in `public/models/README.md`), the shared `airplane.glb` for the remaining civilian classes, and the military layer maps weight classes (real GLBs / 747 heavies / `jet.glb` fastjets, per-model heading offsets, flat amber or emergency red). Textured civilians carry a HEAVY tint, not a light one: `MODEL_COLOR_BLEND_AMOUNT` is `0.94` in BOTH layers under Cesium's `ColorBlendMode.MIX`, so the class colour supplies 94% of the surface and the asset's own texture ~6%. The visual direction is clean light silhouettes with only a weak diffuse contribution from the approved textures, so liveries deliberately do NOT read. IR boost raises the blend to a full `1.0`. Under NVG/FLIR (map preset or Cockpit vision) models render unlit flat-white at full alpha and scene fog is disabled (fog otherwise blacks out distant models with the globe hidden); state restores on exit.
 - The DISPLAY-rail `3D` toggle is the user-facing activation path for both aircraft layers. Their small approved GLBs build their render resources without Cesium's frame-spread job queue, preventing continuous Photorealistic 3D Tiles streaming from starving model readiness; model caps, tracking, camera, and fallback billboards are unchanged.

+## Style
+
+- Mainland usage and Simplified characters. Address the user neutrally, without 您/你 where a plain imperative works: 「点击地图」, 「重试」.
+- Chinese has no case: an UPPERCASE English HUD label becomes the same short Chinese label. Keep labels as short as the English: 「实时」, 「过期」, 「关」.
+- Full-width punctuation in Chinese text: ，。：；？！（）“”. A dash is 「——」 without spaces; keep `·` as the HUD separator and `…` for ellipsis.
+- One space between Chinese and Latin letters or digits: 「AIS 船舶」, 「24 小时」, 「{count} 个」. No space next to full-width punctuation.
+- Units: km, m, km/h, m/s, kn, ft, MW, °, % stay as written; time words are 小时, 分钟, 秒 after a number (「5 分钟前」).
+- Product names, provider names and codes stay as they are: Google, Cesium, CelesTrak, NOAA, FIRMS, AIS, ADS-B, GNSS, CCTV, HUD, CRT, NVG, FLIR, WHOT/BHOT, Ironbow, CONUS.

-# 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. **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.

-
-## 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.

-## 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

-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)                                   |
-| ------------------- | -------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------- |
-| Pace                | Fast, ephemeral, scrolls away                                                                                              | Considered, persistent, threaded                            |
-| Shape               | One-line chat, emotes, @mentions, slow mode, viewer count                                                                  | Posts with kinds (§11.3), replies, quote-posts, attachments |
-| 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.
-
-### 12.7 Tabs
-
-**Today · Live · Capture · Rooms · You**
-
-- **Today**: the brief plus the feed.
-- **Live**: the globe, time machine and lenses.
-- **Capture**: Look · Witness · Live · Upload, plus Need eyes requests near you.
-- **Rooms**: live rooms, crews and Moments.
-- **You**: Signal, receipts, captures, watchlist and alert rules.
-
-Search (the tab-bar search button) leads to dossiers.
-
-### 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.
