 # Changelog
 
+## [Unreleased]
+
+## [0.3.0] — 2026-10-27 — Street Level, On Your Phone, in Your Language
+
+- Show a Street Level view facing 359.5° or more as 0°. The viewer caption
+  rounded the bearing without wrapping, so a view facing 359.6° read "360°"
+  (Aditya, @Rohilalala, #1431).
+
+- The visual styles and their presets mark their labels with the catalog-free
+  `msg()`, so the share-link codec, and any server that loads it, no longer
+  bundles every translation catalog (about 0.9 MB) (samehkhamis, #1421).
+
+- Keep a location search that found nothing, or failed, in the field so it can
+  be corrected: the query stays, focused and selected, and a persistent
+  announced message under the search row says what to do next, instead of a
+  toast followed by a cleared and closed field (samehkhamis, #1420).
+
+- Hosts can read share links on their server: the share-link codec and the
+  `/share/<code>` address helpers are now package exports,
+  `@gods-eye-view/core/share/view-codec` and `@gods-eye-view/core/share/link-path`
+  (samehkhamis, #1419).
+
+- Share links are now short: the share button makes `/share/<code>` links
+  that open on any copy of the app, follow the aircraft, military aircraft or
+  satellite you were following, and fall back to its last-known position with
+  a notice if it isn't reporting. A mistyped link is refused instead of
+  opening a different view. Long `#v=2` links keep working (samehkhamis, #1418).
+
+- Make Clear All clear the saved and shared layer selection. Layers that a
+  context mode had already switched off no longer stay in the share link and
+  come back on reload (samehkhamis, #1417).
+
+- Restore a share link opened in an already-open tab. Pasting a link into the
+  address bar, following one, or using Back/Forward now moves the camera and
+  restores the style, map, panels and layers instead of changing only the URL
+  (samehkhamis, #1416).
+
+- Add a Scope checkbox and extend feathering to 200%, retaining scope settings
+  across HUD layouts, share links and scenes. First run opens with Scope ON at
+  100% feather; explicit settings and historical links retain their values. Give
+  Tactical, Operator and Minimal text black backplates only when Scope is OFF,
+  including vertical metadata, without changing the original HUD text color, glow or
+  opacity. Scope ON retains its original HUD presentation (bilawalsidhu, #1410).
+  Keep title and tagline positions stable when toggling Scope, include the eye
+  in the title backing, and brighten the two secondary labels only with Scope OFF.
+
+- Remove four modules nothing in the app imports: `src/app/sourceSlot.js`,
+  `src/data/flowTiles.js`, `src/data/issPass.js` and `src/data/localGeojson.js`.
+  The local GeoJSON layer tests now build layers the way the catalog does, so
+  they keep covering `localGeojsonCore.js`. Package exports are unchanged
+  (samehkhamis, #1403).
+
+- Aircraft on the ground keep getting ground-height samples after the
+  computer's clock steps back, instead of waiting for it to catch up
+  (quanticsoul4772, #1399).
+
+- The Sharpen slider at 0 now turns the sharpen pass off instead of still
+  sharpening at a low amount (quanticsoul4772, #1398).
+
+- Show a locally heard aircraft tracking 359.5° or more as TRK 0°. The Local
+  ADS-B card rounded the track without wrapping, so 359.7° read "TRK 360°"
+  (Rudy Celekli, @rudycelekli, #1396).
+
+- Report a fire detection's acquisition time as a UTC timestamp in
+  `get_active_fires`. The tool joined FIRMS's unpadded date and time, so a
+  00:45 UTC detection read "2026-01-01 45"; it now reads
+  `2026-01-01T00:45:00.000Z`. Missing or invalid dates and times remain
+  unknown rather than rolling into another calendar day
+  (Rudy Celekli, @rudycelekli, #1395).
+
+- Report Docker container health with a local HTTP check using Node, with the
+  same port parsing as the launcher (John Rogers, @14traits, #1394).
+
+- Start the Docker install on SELinux hosts such as Fedora and RHEL. Compose now
+  mounts the checkout with `:z`; without it the container could not read `/app`
+  and stopped with "Cannot find module '/app/scripts/docker-start.mjs'"
+  (Anıl Güvenç, @anilguvenc, #1391).
+
+- Render awareness-overlay bearings and courses that round through north as
+  `000°`, rather than `360°` (Rudy Celekli, #1390).
+
+- Show cockpit wind from 359.5° or more as 0°, not 360°. Rounding 359.6°
+  printed "N · 360°" on the local wind direction
+  (Rudy Celekli, @rudycelekli, #1389).
+
+- Show a drawn line of 999.5 m or more as 1.0 km. The draw hint kept metres
+  below 1000, then rounded 999.6 m up to "1000 m"
+  (Rudy Celekli, @rudycelekli, #1388).
+
+- Show a Contacts entry 999.5 m or more away as 1.0 km. The panel kept meters
+  below 1000, then rounded 999.6 m up to "1000 m"
+  (Rudy Celekli, @rudycelekli, #1387).
+
+- Show a route leg of 995 m or more as 1.0 km. The route summary and step
+  cards kept meters below 1000, then rounded 996 m up to "1000 m"
+  (Rudy Celekli, @rudycelekli, #1386).
+
+- Show a route leg of 59.5 seconds or more as 1 min. The route summary and step
+  cards kept seconds below 60, then rounded 59.6 s up to "60 s"
+  (Rudy Celekli, @rudycelekli, #1385).
+
+- The HUD's AI place summary drops a reply that arrives after the camera has
+  started moving, so a summary asked for before a flight no longer names the
+  old place mid-flight. Cancelled or partially typed summaries retry even if the place
+  context stays the same (quanticsoul4772, #1384).
+
+- Reduce repeated work in aircraft detection candidates by caching unchanged
+  callsign/registration text and reusing resolved fleet models. Metadata updates,
+  live positions and tracked-aircraft/model handoffs remain immediate
+  (samehkhamis, #1379).
+
+- Increase touch-first globe zoom sensitivity to three times the default while
+  retaining Cesium collision and distance limits.
+- Reuse one delayed display timestamp per civil-aircraft fleet update and cache
+  extrapolation coordinate frames until their fix coordinates change. Preserve
+  contact counts, movement cadence, tracked motion and ground corrections.
+
+- Turning a layer off frees the memory its entities held. Cesium kept
+  removed layers' draw commands in reused per-pass arrays, so Data Centers
+  kept 116 MiB after it was switched off, submarine cables 74 MiB and dams
+  30 MiB; they now keep 13, 9 and 9 MiB (quanticsoul4772, #1367).
+
+- Aircraft 3D models (Flights, Military Flights, Local ADS-B) skip Cesium's
+  dynamic environment map, a sky render and GPU readback per model. With
+  ~150 models in the scene at Atlanta on Google 3D, GPU time per frame at
+  rest falls from 14.3-14.8 ms to 12.1-12.5 ms; a same-model comparison
+  showed no visible change (quanticsoul4772, #1366).
+
+- Drop the decimal when fire radiative power rounds to 10 MW. A 9.96 MW
+  detection was labeled 10.0 MW because the one-decimal cutoff ran before
+  rounding (Rudy Celekli, @rudycelekli, #1354).
+
+- Count a transit report that is 90 seconds old as one minute. The card kept
+  seconds through 89s, then rounded 90s up to "Reported 2 min ago"
+  (Rudy Celekli, @rudycelekli, #1353).
+
+- Read a destination heading that rounds to north as 000. 359.6° was shown as
+  360° on the destination bearing while the compass tape already uses 000
+  (Rudy Celekli, @rudycelekli, #1352).
+
+- Keep a tracked vessel's speed, course, heading and fix time when AISStream
+  static data arrives; the static message only merges name, type, destination
+  and IMO (rudycelekli, #1351).
+- Apply changed static metadata immediately, retaining known fields when a
+  later static report omits them, without refreshing the vessel's position
+  (samehkhamis, #1351).
+
+- Convert NHC cyclone movement speed from miles per hour to knots, so
+  `movement.speedKt` in cyclone query results is no longer about 15% high
+  (rudycelekli, #1350).
+
+- Label NHC cyclone classifications by their published meanings: `PTC` is a
+  post-tropical cyclone, `PC` a potential tropical cyclone, and subtropical
+  systems arrive as `STS` and `STD` (rudycelekli, #1349).
+
+- Wake staged weather imagery on a 150 ms timer while waiting for readiness,
+  avoiding a continuous render loop and cancelling the wake when work ends
+  (@nu-stats, #1345).
+
+- Phrase slight and sharp ramps as directions, so a ramp reads "slightly left"
+  instead of "on the slightly left", and a lane names its side in both
+  the proxy response and localized browser instructions
+  (Rudy Celekli, @rudycelekli, #1343).
+
+- Keep an impossible wildfire acquisition date off the detection clock, so a
+  fire is not labeled with a later day it did not happen
+  (Rudy Celekli, @rudycelekli, #1342).
+
+- Reject impossible KartaView photo timestamps, so 31 February is unknown
+  instead of rolling forward into March and passing the imagery date filter
+  (Rudy Celekli, @rudycelekli, #1341).
+
+- Read a hemisphere letter that is separated from its number, so a search for
+  `40.7128 N 74.0060 W` flies there instead of falling through to the geocoders
+  (Rudy Celekli, @rudycelekli, #1340).
+
+- Carry HUD LAT/LON seconds that round up to 60.00" into the minutes and
+  degrees, so longitude -122.35 reads `122°21'00.00"W` instead of
+  `122°20'60.00"W` (rudycelekli, #1339).
+
+- Improve touch selection of aircraft and vessels through the shared contact
+  picker, reveal tracked aircraft details when opening Context, support downward
+  swipe dismissal of phone drawers while preserving scrolling and controls, and
+  enlarge the phone logo (samehkhamis, #1338).
+
+- Evict terrain-height cache entries in fetch-time order without repeatedly
+  sorting the full cache, while keeping refreshed points newest and ordering
+  restored entries by their fetch time (daikaginza, #1326).
+
+- Add a phone layout for viewports 720px and narrower: the globe stays full
+  screen and a bottom tab bar (Layers, Cameras, Context, Search, More) opens one
+  panel sheet at a time, keeping attribution visible and scene STOP reachable.
+  Adapted from the phone tab-shell in #203 by blearymoth (samehkhamis, #1325).
+
+- Export the KartaView and Panoramax Street Level providers, so a host composing
+  its own provider list can offer the keyless providers without Mapillary
+  (samehkhamis, #1324).
+- A Mapillary source can take a `graphEndpoint`, a Graph API base that adds the
+  token itself (such as a same-origin proxy). Its sequence lookups go there
+  through the source's transport, and the photo viewer uses MapillaryJS's
+  Graph provider at that endpoint, so no client token is needed in the page
+  (samehkhamis, #1324).
+
+- Remove dead code across the repository: three modules nothing imports
+  (`src/ui.js`, `src/standalone/ui.js`, `src/data/localLayers.js`), exports
+  and locals nothing reads, a duplicate copy of the bundled dams data and an
+  unused ship model. The app no longer builds an unused default wind layer
+  and Bhote Koshi locator layer when it loads. Package exports are unchanged
+  (samehkhamis, #1321).
+
+- Validate provider response formats, strengthen camera source checks, and apply consistent API response protections (samehkhamis, #1317).
+
+- Clarify shared field CSS ownership: CCTV owns calibration editor sizing,
+  while Radio and Cyber supply explicit field palettes without changing the
+  current appearance or native control behavior (mazy1998, #1309).
+
+- Share read-only status badge presentation across CCTV source/frame labels,
+  calibration provenance and Weather coverage, preserving status meanings,
+  palettes, translations and announcements while preparing the view contract
+  for a future Vue migration (mazy1998, #1306).
+
+- Share native dropdown and numeric-field styling across Scene, CCTV, Display
+  and Radio controls, with a shared CCTV number-input builder that preserves
+  existing precision, validation and commit behavior (mazy1998, #1305).
+
+- Point distances wrap longitude differences across the antimeridian, in voice
+  proximity checks and `places_nearby` (quanticsoul4772, #1304).
+
+- `get_wind` flags stale forecasts (`stale`) when the wind proxy serves a
+  cached model run (quanticsoul4772, #1303).
+
+- Give ordinary Scene and CCTV actions shared native buttons with consistent
+  default, destructive and compact styling while preserving their existing
+  behavior and specialized controls (mazy1998, #1302).
+
+- Unify segmented selectors for model coverage, detection allocation, drawing
+  shape, Street View and imagery comparison while preserving their existing
+  behavior. Keep compact labels such as FILL and FLAT on one line, and let
+  collapsed Weather release space to the open rail panel. Reserve the full mode
+  button height in Recent Imagery so keyboard focus is not clipped (mazy1998, #1301).
+
+- Add a shared Voice Preview and Settings panel with browser-local preferences,
+  inactivity controls and accessible floating provider controls on compact layouts;
+  recover inactivity after confirmed audio-less replies, release retired audio
+  observers and keep cost warnings visible outside Settings
+  (manjunath22466, #1299).
+
+- Add Simplified Chinese (zh-CN) to the language picker, with localized dates
+  and readable Chinese labels. Based on translations by @abiyeenzo (#914)
+  and @EDIT-Aeterna (#979).
+  (German, @gekh, #1298).
+
+- Add the S2 GhostMaps layer: S2 Underground's public KMZ intel products
+  (Common Intelligence Picture, 30-day kinetic pull, Border Crisis Map, Iran
+  and Yemen products and the newest incident drop) from
+  github.com/s2underground/GhostMaps, with one chip per product and report
+  cards on click. `/api/ghostmaps` watches the repository's branch head every
+  15 s and pushes each new commit to open pages, which reload only the
+  products that changed (Black Pine Defense).
+- Clear a temporary GhostMaps upstream error and notify open pages when the
+  repository becomes reachable again, including when no new edition was published.
+- Release packed-image resources when a load is cancelled or fails, respect
+  injected or omitted GhostMaps sources, and wait for background cache warm-up
+  before removing provider test fixtures.
+- Include Simplified Chinese translations and keep the combined voice prompt
+  within its existing size limit while retaining all spoken aliases.
+
+- A Street Level provider whose `zoomFor` still answers `{zoom, kind}`, the
+  shape before the core went slim, draws its lines again instead of a silent
+  blank; an overview level or any answer that is not a whole zoom shows the
+  zoom-in hint (asturksever, #1288).
+
+- Give ordinary sliders a shared native control and consistent track, thumb,
+  value, focus and disabled styling while preserving feature behavior and
+  specialized controls (mazy1998, #1287).
+
+- The Street Level SINCE note sits on the value's line, in its type and a
+  size smaller: with KartaView lit it reads ANY DATE (by upload date). It
+  had lost its size variable in the Street Level slim-down and rendered
+  larger than the value, on a line of its own (asturksever, #1286).
+
+- Keep aircraft route labels on the scheduled airport leg instead of accepting
+  its distant great-circle extensions, preserving generous endpoint tolerance
+  across the signed-angle branch cut (rudycelekli, #1284).
+
+- Report cached CelesTrak satellite records as stale in the Data Layers row,
+  preserving separate core and dense catalog provenance through refresh,
+  removal and lifecycle cleanup (rudycelekli, #1283).
+
+- Pause periodic network updates in hidden tabs; the overdue update on return restarts the polling schedule, so the next poll follows one interval later even when that update fails (asturksever, #1282).
+- Report and guard browser visibility during Transit QA so hidden-page polling pauses cannot masquerade as playback regressions (asturksever, #1282).
+- Require each live city to supply its own feed vehicles in Transit QA; retained vehicles cannot qualify another city (asturksever, #1282).
+- Bound the Transit card-anchor probe by observed poll coverage instead of a fixed 20-second window (asturksever, #1282).
+- Keep visible-page Transit probes focused through the browser testing API (asturksever, #1282).
+- Add a real-browser regression gate for hidden-tab periodic work, explicit refresh, resume and teardown (asturksever, #1282).
+- Restore minimized test windows before screenshots so native compositor pauses cannot stall browser acceptance (asturksever, #1282).
+
+- Hold rendering only for animated content (asturksever, #1281).
+- Exercise current vector road sources and published camera bounds in Traffic fixture QA (asturksever, #1281).
+- Establish browser-level foreground visibility for Traffic QA and reject hidden-page samples (asturksever, #1281).
+- Supply CORS headers on cross-origin traffic fixtures and report browser exceptions without disabling browser security (asturksever, #1281).
+- Isolate the Traffic keyless browser scenario from the keyed page’s workers and intercepted cache (asturksever, #1281).
+- Restore minimized test windows before screenshots so native compositor pauses cannot stall browser acceptance (asturksever, #1281).
+- Intercept only Traffic provider URLs, leaving Cesium worker and module loading untouched (asturksever, #1281).
+- Settle an unfinished Traffic height correction when the last animated point leaves, so the layer stops reporting loading once its render hold is released (asturksever, #1281).
+
+- Throttle mission hover picks with a trailing check for the last pointer position, and clear stale cursors (asturksever, #1279).
+
+- Reserve singleflight before disk cache reads (asturksever, #1278).
+
+- Bound each height request to one upstream chunk (asturksever, #1276).
+
+- Preserve enable during first-load replacement (asturksever, #1275).
+- Release disabled weather camera listeners and make teardown resource leaks fail the browser probe (asturksever, #1275).
+- Keep visible-page weather teardown probes focused through the browser testing API (asturksever, #1275).
+
+- Scan the kml root delimiter in bounded time (asturksever, #1274).
+
+- Retire unavailable history and keep local trails (asturksever, #1273).
+
+- Normalize geocoder bias across the antimeridian (asturksever, #1272).
+
+- Reject inherited style keys during restore (asturksever, #1271).
+
+- Respect provider cooldowns and bound tle groups (asturksever, #1270).
+
+- Coalesce refreshes and cool down opensky failures (asturksever, #1269).
+
+- Normalize station tags and retain valid mixed rows; skipped malformed rows still report degraded coverage (asturksever, #1268).
+- Correct Radio QA push-to-talk setup to target the mounted voice controller (asturksever, #1268).
+
+- Honor Docker Compose trusted-peer and allowed-host settings from the shell
+  or project `.env`, and let `GEV_KEY_SETUP_TRUSTED_PEERS=none` disable gateway
+  access to Provider Settings before Vite starts (asturksever, #1265).
+
+- Prevent malformed Overpass filters from blocking the local server, and reject
+  cross-site or excessive query requests before reading their bodies
+  (asturksever, #1264; fixes #1248).
+- Release unread responses from the optional Google-token probe so keyless
+  browser validation can settle; the Overpass gate recognizes only that probe's
+  expected 404 as an unavailable capability (asturksever, #1264).
+- Make tracking arrival checks respect the aircraft update cadence while checking
+  orientation on the first reveal, avoiding false failures at faster render
+  rates (asturksever, #1264).
+
+- The terrain-heights bounds tests no longer read the checkout's
+  `.gev-cache/terrain-heights.json`. Each test gets a cache file of its own, so
+  `npm test` no longer fails after the dev server has cached terrain near
+  Austin (KnottyDyes, #1244).
+
+- Replace the blocky JPEG sky around the globe with the 9,096 stars of the
+  Yale Bright Star Catalogue, drawn as sharp points where they are at the
+  scene time, over a soft Milky Way from ESO/S. Brunier (CC BY 4.0). The Sun
+  and Moon stay; the anime style hides the Milky Way. Assets: 296 kB (gekh,
+  #1243).
+
+- `get_traffic_flow` flags stale cached TomTom tiles and reports the oldest
+  tile fetch time (`stale`, `oldest_tile_at`), with pending freshness metadata
+  released on failed or cancelled tile reads (quanticsoul4772, #1239).
+
+- Add Taiwan's national freeway cameras from the Freeway Bureau, MOTC to CCTV:
+  ~1,800 cameras read at runtime from the official MOTC 2.0 open-data table,
+  with on-demand snapshots and attribution. No API key is required; set
+  `CCTV_TAIWAN_ENABLED=0` to skip it (419vive, #1237).
+
+- Require a geocoded containment anchor for ambiguous analyst region names,
+  preserve boundary provenance and cancellation safety, and retain exact-name
+  precedence for natural outlines (manjunath22466, #1235).
+
+- Serve the camera catalog while it refreshes. An expired catalog made every
+  camera request wait for the slowest pack to reload; it is now answered at
+  once while one background refresh runs, so only the first load waits. Estonia's
+  slow Tarktee feeds get 30 s instead of 15 s, so the pack no longer drops out
+  on about a third of loads (quanticsoul4772, #1234).
+
+- Harden the Tarktee (Estonia) DATEX2 camera catalog fetches: refuse redirects,
+  cancel both response streams when either response fails or overflows the 4 MB
+  byte cap, and deduplicate camera IDs before per-pack prioritization
+  (yaka0007, #1233).
+
+- Skip bike-share stations with missing, blank or invalid coordinates instead
+  of placing them at coerced zero coordinates or accepting out-of-range values.
+  Explicit zero coordinates and numeric strings remain supported (Bortlesboat, #1232).
+
+- OpenSky sign-in matches what OpenSky accepts since 2026-03-18. The server
+  now reads `OPENSKY_CREDENTIALS_FILE` (the `credentials.json` OpenSky's
+  account page downloads) on every platform, not only through the macOS
+  launcher, and no longer sends retired username/password Basic auth:
+  `OPENSKY_AUTH_MODE=basic` loads anonymously with one warning saying what to
+  set instead (quanticsoul4772, #1229).
+- Credential-file warnings omit parser excerpts and filesystem error details;
+  the path example also works with the macOS launchers.
+
+- Load Ontario 511 cameras again. 511on.ca's camera endpoint now requires a
+  free developer key; set `ONTARIO_511_API_KEY` to enable the pack, which is
+  otherwise skipped with one log line saying where to get a key
+  (quanticsoul4772, #1228).
+
+- The first-run card can be closed on a phone or tablet. "ESC to dismiss" is
+  now a button that closes the card the same way ESC does; touch screens read
+  DISMISS, and phones no longer hide it, so choosing a mission is not the only
+  way out (KnottyDyes, #1226).
+
+- Add continuous globe rotation with direction and speed controls and a globe-fit
+  check before starting (manjunath22466, #1225).
+
+- Open God's Eye View from Pinokio in the system browser using the supported
+  `popout` menu option. The application's framing policy is unchanged
+  (NukeThemAII, #1222).
+
+- Avoid starting or queuing a reply when the local channel rejects a typed OpenAI
+  command, while preserving an earlier accepted deferred input
+  (Manjunath, #1220).
+
+- Keep NASA FIRMS fire and ALPR camera labels English in voice tool results
+  (`track_entity`, `get_entity_context`, pointer context); the voice card still
+  shows them in the interface language (daikaginza, #1207).
+
+- Report actual outcomes when voice enables or disables CCTV through the shared
+  layer lifecycle, including failed and cancelled changes (manjunath22466,
+  #1205).
+
+- Draw CCTV stills at their source aspect on the monitor plane instead of
+  stretching them to the 16:9 canvas. Most DOT cameras publish 4:3 frames, so
+  every still was widened; they are now centered and pillarboxed on the dark
+  the placeholder already ends on (Danielslay86, #1201).
+
+- Color CCTV cameras with a video feed violet. Cameras with an HLS, MP4 or
+  WebM feed were the same cyan as stills, so a DelDOT or Statens vegvesen
+  video camera could only be found by opening it. Stills stay cyan and the
+  active camera stays amber, and focus de-emphasis fades the violet the same
+  way (Danielslay86, #1200).
+
+- Keep Space Missions marked STALE when Launch Library 2 falls back to cached
+  launch data, and return to NOMINAL after a fresh response without discarding
+  retained missions (rudycelekli, #1199).
+
+- Share Launch Library request cache keys across installations refreshing in the
+  same UTC minute, identify the app to the provider, and explain that standard
+  space-missions access needs no key. Optional higher-rate LL2 tokens are paid
+  upgrades; existing local cache and server-only token handling are unchanged
+  (rudycelekli, #1197).
+
+- Add nine Spanish city bike systems to Bike Share and `get_bike_share`: BiciMAD
+  (Madrid), Valenbisi (Valencia), Bizi Zaragoza, Sevici (Seville), BIKI
+  (Valladolid), BiciCoruña, Dbizi (Donostia-San Sebastián), Bilbao Bizi and
+  BicinRivas, about 1,840 stations. Station names read underscores as word
+  breaks, and station capacity counts docks rather than PBSC's geofenced area
+  (ulihhhh, #1190).
+
+- Keep missing launch-pad coordinates unknown so launches use the location
+  fallback or stay off the map instead of appearing at 0°N 0°E. Missing stage
+  flight numbers no longer show "FLIGHT 0"
+  (Rudy Celekli, @rudycelekli, #1186).
+
+- Flights' ground floor works across the antimeridian. The viewer-distance
+  check behind the 150 km floor radius and its copy in the photoreal mesh-floor
+  sampler subtracted longitudes without wrapping, so two points 21 km apart
+  across 180° measured about 38,000 km and low or grounded aircraft just across
+  the line from the viewer were never floored. A contact's display corridor
+  walked a segment across 180° the long way round, spending its cell budget on
+  ground behind the contact, and a contact on the seam lost its cell hysteresis.
+  SEARCH NEARBY SITES on a view across 180° searched Google Places around
+  longitude 0, on the far side of the globe, with a radius sized from the view's
+  height alone; it now searches the view (Aditya, @Rohilalala, #1173).
+
+- Keep missing CCTV numbers unknown instead of reading them as zero. `Number`
+  turns null, blank strings and booleans into 0 or 1, and the camera source
+  list sends an unknown number as JSON null, so a source-pack camera that left
+  out its pose reached the browser as zeros clamped to each field's floor —
+  facing north, pitch −2°, FOV 20°, range 120 m, mount 6 m and ground 0 m —
+  instead of the defaults (id-hash heading, −17°, 74°, 700 m, 24 m and the
+  city's ground); a null or blank position placed the camera at 0,0. The
+  server's `toFiniteNumber` and the browser's `safeNumber` now treat absent,
+  blank and boolean values as missing. The same conversion also stops a
+  Tallinn row with a null heading reading as a confident north-facing camera,
+  a Caltrans camera with a blank elevation losing its 150 m ground prior, and
+  a TfL or Catalonia camera with a null or blank coordinate being kept at 0,0
+  or on the zero meridian (omerbberk, #1172).
+
+- Director shot actions land on the requested shot. A seek to a shot's start
+  could round a hair below it and select the end of the previous shot for some
+  shot counts and durations (Aditya, @Rohilalala, #1171).
+
+- Fire-perimeter queries handle outlines and holes crossing the antimeridian:
+  areas enclosed near ±180° are included, areas at the opposite meridian are
+  excluded, and returned perimeter coordinates stay near the dateline. Incident
+  cards use the same circular longitude mean and compare multipart outline
+  areas along short longitude edges, keeping the card on the largest polygon
+  (Arianna Method, @ariannamethod, #1142).
+
+- Scenes keep the "Scene not saved" status when a capture, update, append or
+  import cannot be saved, and an unreadable saved project no longer overwrites
+  the recovery checkpoint. `startScene()` resolves to its documented result,
+  `afterShotId` works without an explicit scene, and `scenesRun` counts the
+  distinct scenes queued (djabhi31, #1135).
+
+- Label camera-tool Street View fallbacks as historical Google imagery rather
+  than the current camera view; keep unknown frame provenance explicit
+  (rudycelekli, #1118).
+
+- Release superseded Google Street View open waits and suppress metadata
+  requests whose viewer was unmounted while the service loaded (rudycelekli,
+  #1117).
+
+- Exclude aircraft without a reported altitude from requested altitude bands;
+  unfiltered aircraft queries still retain them (rudycelekli, #1115).
+
+- A failed Esri Satellite or keyless terrain load still shows OSM or flat terrain
+  at once, but no longer lasts the whole session: while the fallback is on
+  screen, the real provider is retried in the background (30 seconds, doubling
+  to a 10-minute cap) and replaces it live once it loads. Map switches never
+  wait for a retry (Aditya, @Rohilalala, #1111).
+
+- Skip TLE sets whose line 1 and line 2 carry different catalog numbers, so a
+  spliced catalog cannot pair one satellite's elements with another's; the next
+  valid set still parses (VG31OP, #1101).
+
+- Overpass data whose element tags contain a failure phrase ("timed out",
+  "runtime error", "too many requests" and similar, e.g. a place named "Timed
+  Out Escape Rooms") is returned as data instead of being refused and putting
+  the endpoint on cooldown; upstream failures are read from the remark (Aditya,
+  @Rohilalala, #1097).
+
+- Military aircraft keep their last heading and speed when an adsb.lol row omits
+  `track` or `gs`, instead of turning north and stopping; a grounded row without
+  a speed still reads 0 (Aditya, @Rohilalala, #1096).
+
+- Update DOMPurify to 3.4.17, Sharp to 0.35.5 and source-map-js to 1.2.2 for
+  GHSA-p98j-92pf-mc4p, GHSA-6688-9rhm-gjv2, GHSA-wq5f-xc86-pv6w and
+  GHSA-68fv-2mgg-jv7q; `npm audit` now reports no vulnerabilities (NurstarK,
+  #1094).
+
+- Location search accepts two-dimensional WGS84 `geo:` URIs offline, with
+  the existing coordinate framing and label. Unsupported URI fields are passed
+  to the remaining search providers unchanged (cj-vana, #1071).
+
+- Keyless standalone startup answers an unavailable Google tile-token endpoint
+  with uncached 204 instead of a browser-visible 404. Existing providers take
+  precedence, and unrelated API routes behave as before. (dvilrgamerz, #1066)
+
+- On Windows, `npm run doctor` and the Pinokio install no longer print Node's
+  DEP0190 warning ("Passing args to a child process with shell option true can
+  lead to security vulnerabilities"): npm.cmd's fixed subcommand is now part of
+  the shell command string instead of an argument array (quanticsoul4772, #1057).
+
+- `aircraft_in_area` and `vessels_in_area` take `group_by` and `stats`, so an
+  MCP client can ask which airlines, countries, aircraft types or ship types
+  dominate an area, or the average altitude or speed, over every match instead
+  of estimating from the returned rows. Airlines come from the ICAO designator
+  in each callsign (SWA1234 counts as SWA), so the breakdown works on feeds
+  that report no operator; operator and type are counted only where the feed
+  reports them. Ship types count by family, so AIS codes 70 to 79 are all
+  cargo; type 0 ("not available") and the reserved codes 100 to 255 count as
+  unknown. Altitude and speed stats cover airborne aircraft only, so parked
+  aircraft do not pull the means down. Every vessel answer, `find_vessel`
+  included, now reads AIS ship-type codes as their family and a destination
+  with no letters as unknown (quanticsoul4772, #1056).
+
+- Add Hong Kong Transport Department traffic snapshot cameras as a keyless CCTV
+  source pack: the public DATA.GOV.HK English locations XML, frames pinned to
+  `tdcctv.data.one.gov.hk`, with DATA.GOV.HK Terms of Use attribution. By
+  default nearly the full TD catalog (~1,013 cameras; cap 1,100) loads,
+  prioritized across Hong Kong Island, Kowloon and the New Territories. Headings
+  use the shared id-hash fallback at low confidence. `CCTV_HK_MAX_SOURCES` sets
+  the cap (8–1,200) and `CCTV_HK_ENABLED=0` turns the pack off (JCY2515, #990).
+
+- Cross-site pages can no longer fill the terrain-height cache or spend the
+  visitor's own `/api/terrain/heights` rate-limit quota through the visitor's
+  browser. The route refuses a cross-site `Sec-Fetch-Site` or a foreign or
+  opaque `Origin` before rate limiting, cache access or upstream work. Unlike
+  the cost-bearing routes it still answers same-origin requests that arrive
+  through a reverse proxy, so terrain keeps rendering behind nginx, Caddy or
+  Cloudflare instead of falling back to the geoid (Sunil56224972, daikaginza,
+  #975).
+
+- Street Level is rebuilt around one small provider registry: Mapillary,
+  KartaView, Panoramax and Google Street View share one coverage drawer and
+  one photo viewer, one source lit at a time. Floating and docked panels,
+  FOLLOW, surface modes, the legend and the Mapillary proxy's disk cache are
+  gone; `.gev-cache/mapillary/` from earlier runs is no longer read and can be
+  deleted (gekh, #974).
+
+- Cross-site browser requests can no longer spend the TomTom traffic-tile
+  budget through `/api/tomtom/*`. The shared same-site gate runs before status,
+  cache, and upstream work; same-origin app requests and non-browser local
+  callers remain supported (Sunil56224972, #973).
+
+- Recent Imagery: opening DETAILS scrolls its card into view when it opens below
+  the fold. The panel used to restore the previous scroll position right after
+  the reveal, so the card stayed out of sight (Ian Blenke, #970).
+
+- Harden Vite's filesystem deny list for local-only artifacts: repo `dist/`,
+  `.gev-logs/`, and `.gev-cache/` are denied without blocking dependency
+  `dist/` directories, and checkout paths containing glob metacharacters are
+  escaped before building the root-anchored pattern (blowing-a-raspberry, #948).
+
+- Give each Statens vegvesen camera its own ground height from Kartverket's
+  keyless point-height API (CC BY 4.0) instead of one flat 150 m prior, so
+  mountain-pass cameras no longer sit hundreds of metres below the terrain
+  where neither the point-height prior nor the ground snap resolves. About 850
+  of ~855 cameras get a height; the rest keep the old prior. Requests carry 20
+  points, the most the API answers from its 1 m terrain model, eight at a
+  time; a cold lookup takes about 6–13 s. Cameras over water use the water
+  surface rather than the sea-floor depth the API returns there; for bridge
+  cameras that is still below the deck. Heights are cached for good and misses
+  for 6 h, so a refresh only asks about new or moved cameras. After a
+  failing request (a 408, 429 or 5xx, a network error, a request over 10 s or
+  an unreadable body) the lookup stops and backs off (Retry-After, else
+  30 min, longer than the refresh). The lane waits at most 12 s from its
+  start, and only on a cold cache; a slower first lookup leaves the cameras it
+  had not reached on the flat prior until the next 15-minute refresh, and
+  keeps filling the cache meanwhile.
+  `CCTV_VEGVESEN_HEIGHTS=0` turns it off. Follow-up to #929 (trygvehhh, #945).
+
+- Extract a reusable model-free World Packet from the existing voice
+  `get_current_view_state` owner without restoring disabled layers to the
+  model context. Keep the enabled-only payload, disabled-layer count, source
+  provenance, action result and view-state contract; read the layer roster once
+  per packet; voice retains the speech/card envelope at its own boundary.
+  Credits: original GEV voice/layer contributors and #880 implementation.
+
+- Add optional Gemini Live voice to the standalone app, with a provider chooser,
+  server-held API key, microphone streaming, shared map actions and captions.
+  Switching providers ends the old conversation and preserves the input mode
+  (Manjunath, #872).
+
+- Close the compact Radio disclosure when an adaptive tactical right-rail
+  restore directly expands Context, before Space Missions can be covered.
+  A repeated Context-open request also clears stale disclosure state.
+  Real PanelChrome constructor wiring and the rail reflow path are covered
+  by focused regressions. Credits: kvnloo (#816), raysung-2026's original
+  #804 report, asturksever's review, and quanticsoul4772's independent
+  Windows diagnosis.
+
+- Changelog entries are now one file per pull request. A change adds
+  `changelog.d/<pull request>-<slug>.md` instead of editing the top of
+  `CHANGELOG.md`, which two pull requests in flight could not share — it was the
+  most frequent merge conflict in the open queue, and for six of them the only
+  one. `npm run changelog` splices the directory into `CHANGELOG.md` at release
+  time and empties it; `npm run changelog:check` reports the batch and changes
+  nothing. Fragment text is copied through unchanged (daikaginza, #787).
+
+- Read satellite catalog numbers written in Alpha-5, the TLE spelling of
+  numbers above 99999: a letter for the first two digits, skipping I and O
+  (`A0000` is 100000, `Z9999` is 339999). The satellites layer converted such a
+  field to `NaN`, so every Alpha-5 satellite shared one catalog entry and all
+  but the first were dropped as duplicates; the satellite tools read the same
+  field as no number, so such a satellite could not be found by it. The layer
+  and the tools now decode the field in `src/sources/tle.js`, and reject a
+  malformed one (a sign, decimal point, hex, embedded space or stray letter)
+  instead of reading part of it as a number. This is Alpha-5 TLE
+  compatibility: CelesTrak's TLE feed carries no satellite above 99999, which
+  needs the OMM feed (#1191) (Honorius Neogy, #767, fixes #751).
+
+- The dev server no longer watches `.gev-cache` and `.gev-logs`. Providers write
+  cache files and logs there while the app runs, and none of it is source, so
+  the watcher now skips it; this guards against the DNS-lookup delays heavy
+  cache writes have caused, though no difference was measured on current main
+  (monwiss, #761).
+
+- Bound what a caller can grow through `/api/terrain/heights`. Every distinct
+  5-decimal point was a permanent in-memory entry, a permanent line in an
+  uncapped `.gev-cache/terrain-heights.json`, and a live upstream call, with
+  nothing limiting the rate. The point cache now holds at most 50,000 entries
+  and evicts oldest-first, a cache file above
+  24 MB is not read back, and the route is limited to 90 requests/minute per
+  client (270 global). Evicting a point costs one refetch, never a wrong
+  answer, since terrain does not move. Ordinary use is unaffected: a full
+  `test:track` run drives 10 requests, peaking at 8/min (daikaginza, #686).
+
+- Add FL511 (Florida DOT) traffic cameras as an opt-in CCTV source pack:
+  the statewide ArcGIS catalog, read a page at a time under a byte cap with
+  redirects refused, and frames pinned to FL511's two image hosts over HTTPS.
+  FL511's terms limit its content to individual, personal use, and any other
+  use (a public deployment included) needs FDOT's express written consent, so
+  the pack stays off unless `CCTV_FLORIDA_ENABLED=1`. Headings come from the
+  catalog's direction codes, and camera ids come from the image channel, since
+  the catalog's ID column repeats across regions. `CCTV_FLORIDA_MAX_SOURCES`
+  sets the cap (Danielslay86, #605).
+
+- The client's great-circle distances now come from one shared
+  `src/geoDistance.js` (`greatCircleKm`/`greatCircleMeters`, `{lat, lon}`
+  points). The Earth radius is standardized on 6371.0088 km, so distances shift
+  by about 1.4 ppm and region areas by about 2.8 ppm, and missing or
+  out-of-range points return `Infinity` (onionviolet, #287; Rajojha-1, #749).
+
 - The tracked-aircraft descriptor now publishes `verticalRateMps`, on both the
   civil and military layers, so a consumer reading `getTrackedInfo()` no longer
   has to reach past it into the raw poll record for climb/descent. Reported,
   never derived: an aircraft that has not transmitted a rate reads as `null`
   rather than a level-flight `0`.
 
+- Bound how often the GBFS proxy will relay. `/api/gbfs` already restricted
+  where it could go — https, an allowlisted host, a station feed path, no
+  redirects, a 12-second deadline and a 5 MB body cap — but nothing restricted
+  how often, so the dev server would make unlimited requests at a third-party

+## Adding a new layer
+
+A new layer changes what everyone sees on the globe, so maintainers need to see
+it working and know where its data comes from before reviewing the code. PRs
+that add a layer must include all four of these in the description. The PR
+template has a section for them.
+
+1. **Screenshots.** At least one of the layer on the globe, plus its info card
+   or panel if it has one.
+2. **A screen recording**, preferably 15 to 30 seconds: turn the layer on, move
+   around, and open a record. Drag an `.mp4` or `.mov` into the PR description.
+   GitHub accepts videos up to 10 MB on free accounts, so link to a larger file
+   instead of attaching it.
+3. **The proposed category.** Say which layer-panel group the layer belongs in.
+   The groups are defined in `PANEL_GROUPS` in `src/ui/layerPanel.js` (today:
+   Movement, Cameras, Infrastructure, Events, Weather and Utilities). A layer
+   that isn't listed there falls under "Other layers". If none of the groups
+   fits, propose a new one and explain why.
+4. **The data source and licence.** Name the provider and endpoint, link its
+   licence or terms, give the attribution shown in the app, and say whether it
+   needs a key and whether the data is fetched at runtime or bundled. Add the
+   same details to [DATA_SOURCES.md](DATA_SOURCES.md) and register the credit
+   in `src/data/dataCredits.js`.

 - **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).

 - **adsbdb enrichment.** `/api/adsbdb` resolves an ICAO hex to aircraft type, model name and registration, and the tracked flight's callsign to an airline and an origin/destination pair. Fan-out is deliberately small because adsbdb is a free community API that publishes no quota: at most 4 requests in flight, dispatches dripped to roughly 5/s, and each key asked for at most once per session, with route lookups reserved for the tracked aircraft. The dev-server proxy caches each key for 24 hours in `.gev-cache/adsbdb.json`, negative answers included, so fresh entries survive server restarts. That gitignored cache remains local to the deployment and is not bundled with this repo. adsbdb publishes no general service license; its README says the route data may not be copied, published, or incorporated into other databases without the explicit permission of David J Taylor, Edinburgh. Deployers are responsible for obtaining any permission their use requires. Enrichment is best-effort and fail-silent — a flight that gets no answer keeps what the flight feed already gave it.
 - **Launch Library 2.** `/api/launches` makes a server-side rolling-30-day query against the supported v2.3 detailed launch endpoint, caches successful responses for 15 minutes in memory and on disk, and serves the last successful response during a throttle or transient outage. Anonymous access is limited to 15 calls/hour; deployments can provide `LL2_API_TOKEN` for authenticated access. The Space Devs' published terms permit using and sharing the API data in any form, ask users not to forward it without adding value, disclaim complete accuracy, and encourage—but do not require—attribution. This app keeps a courtesy credit. Payload and stage/recovery records are shown only when supplied. Failed launches expose their source status and never receive fallback orbit geometry or a live/estimated marker. LL2 supplies launch context and event timing, not continuous ascent telemetry or live orbital state.
 - **TfL JamCams.** The camera list comes from the keyless `api.tfl.gov.uk` endpoint (an optional `TFL_APP_KEY` raises its rate limit); frames come from TfL's public S3 bucket. The "Powered by TfL Open Data" attribution is required by TfL's terms and is registered in the Data attribution popover.
-- **Ontario 511 CCTV.** The camera list comes from the keyless `511on.ca/api/v2/get/cameras` endpoint; frames are server-registered still images under `511on.ca/map/Cctv/`. The source is live-fetched at runtime and attributed under the Open Government Licence - Ontario.
+- **Ontario 511 CCTV.** The camera list comes from the `511on.ca/api/v2/get/cameras` endpoint, which now requires a free developer key (`ONTARIO_511_API_KEY`: sign up at 511on.ca/my511/register, then request it while logged in at 511on.ca/developers/doc; throttled to 10 calls a minute). Without the key the pack is skipped. Frames are server-registered still images under `511on.ca/map/Cctv/`. The source is live-fetched at runtime and attributed under the Open Government Licence - Ontario. Access is governed by Ontario 511's Developer's Access Agreement (511on.ca/developers/resources): the data stays under the Open Government Licence - Ontario unless otherwise specified; key requests are reviewed case by case and ask for the intended use and any third parties that will receive the data; attribution by link to 511on.ca is encouraged, and the Ontario 511 logo may not be altered or used to imply endorsement (this app links and shows no logo); and the data is provided "as is", a disclaimer distributors should pass on, which the credit does.
 - **DelDOT live video cameras.** The keyless `tmc.deldot.gov/json/videocamera.json` catalog supplies active cameras and official `https://video.deldot.gov/live/…/playlist.m3u8` links. The local server transiently buffers bounded MPEG-TS segments in memory and deletes them on session release or idle expiry. No recordings are retained. `CCTV_DELDOT_ENABLED=0` disables the pack. Public availability is not a blanket redistribution license; deployment beyond personal local viewing needs confirmation of applicable DelDOT terms.
 - **Fintraffic weathercams.** The camera list is one keyless GeoJSON request to `tie.digitraffic.fi/api/weathercam/v1/stations` (809 stations / 2,275 presets), sent with the `Digitraffic-User: gods-eye-view` header the service asks clients to identify themselves with and with gzip; frames are stills on `weathercam.digitraffic.fi`, refreshed on each station's 600 s collection interval, which is also the client's ambient-still refresh cadence for this pack (the active camera keeps the usual 10-second refresh). One preset (a fixed camera view) is one camera; stations not `GATHERING` and presets not `inCollection` are dropped. Attribution is required by the CC BY 4.0 licence and is registered in the Data attribution popover. `CCTV_FINTRAFFIC_ENABLED=0` is the kill switch.
 - **DriveBC highway cameras.** The camera list comes from the keyless `https://www.drivebc.ca/api/webcams/` endpoint served by the DriveBC.ca site ([bcgov/DriveBC.ca](https://github.com/bcgov/DriveBC.ca)); frames come from `https://www.drivebc.ca/images/<id>.jpg`, built from the numeric camera id. DataBC's [DriveBC HighwayCams](https://catalogue.data.gov.bc.ca/dataset/bc-highwaycams) catalogue entry publishes the same cameras under the Open Government Licence – British Columbia, but its CSV still lists the retired `images.drivebc.ca` frame URLs, which now return a placeholder. The licence's attribution statement is required and is registered in the Data attribution popover. By default the 250 cameras nearest Vancouver and Victoria load; `CCTV_DRIVEBC_MAX_SOURCES` changes the cap and `CCTV_DRIVEBC_ENABLED=0` turns the pack off. Some cameras in the feed are supplied by partners (TransLink, the City of Vancouver, the City of Surrey, Parks Canada / Alberta Motor Association and others); the feed's per-camera credit is carried onto the camera record and shown beside the provider in the CCTV panel.

 - **Warendorf webcam.** The Stadt Warendorf Marktplatz webcam, registered from the curated `config/cctv_sources.warendorf.json` (the Kreis Warendorf registration-office cameras from the contributing PR are indoor waiting rooms and were left out); only the municipal image host is proxied, frames are fetched at request time and never stored or redistributed. Disable with `CCTV_WARENDORF_ENABLED=0`.
 - **Live Traffic NSW cameras.** The camera list is the keyless public `data.livetraffic.com/cameras/traffic-cam.json` feed (Transport for NSW open data, CC BY 4.0); frames are stills on `webcams.transport.nsw.gov.au`, and only that host is registered. That image host answers non-browser clients with an HTML placeholder, so the proxy identifies as a browser for that one host and as itself everywhere else. Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_NSW_ENABLED=0`.
 - **Open Calgary traffic cameras.** Keyless. The camera list is the public Socrata dataset `k7p9-kppz` on `data.calgary.ca`; frames are stills on the city's own `trafficcam.calgary.ca` host, and only that host is registered. Most rows publish an `http://` frame URL and the host redirects those to HTTPS, so URLs are upgraded and pinned to that origin before registration. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `quadrant` field and the quadrant suffix on each camera name are Calgary's address grid, not a bearing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. The licence requires the attribution statement above. Disable with `CCTV_CALGARY_ENABLED=0`.
+- **FL511 Florida cameras.** Off by default; set `CCTV_FLORIDA_ENABLED=1` to load them. The camera list is the keyless FL511 traffic camera layer on ArcGIS (`services.arcgis.com/.../FL511_Traffic_Cameras`), published from a Florida Division of Emergency Management account rather than by FL511 directly, and the service carries no licence text of its own. It is paged up to 2,000 rows at a time, ordered by the layer's object id and following ArcGIS's `exceededTransferLimit`, to cover the ~4,000-camera statewide set. Frames are stills on two Divas Cloud hosts (`images-dis.divas.cloud`, `snapshots.divas.cloud`); both are host-pinned and a row whose image resolves elsewhere is dropped. `CCTV_FLORIDA_MAX_SOURCES` caps the pack (default 500, anchored per region across the state). Each catalog page is read under a 2 MiB cap and redirects are refused. Frames are fetched live at request time and never stored or redistributed. FL511's terms (fl511.com/privacy#disclaimer) license its content for individual, personal use only; any other use, including a public deployment, needs FDOT's express written consent.
 - **Catalonia (Servei Català de Trànsit) cameras.** The camera list is the keyless `https://www.gencat.cat/transit/opendata/cameres.xml` WFS/GML feed, fetched over https with redirects refused and the body read capped at 1 MiB, since the list decides ids, coordinates and which allowlisted frame path is proxied. It carries a `font` field naming the real publisher per camera; this pack keeps SCT's own highway cameras plus hotlinked Barcelona (IMI) and Terrassa municipal cameras (~130 total), each confirmed to return a real frame, so frame URLs are checked against a small host allowlist (`mct.gencat.cat`, `www.bcn.cat`, `emap.terrassa.cat`) rather than one pinned origin (a link carrying `user:pass@` userinfo or an explicit port, or pointing outside that host's frame directory, is rejected even on an allowed host; an SCT `sctidcam` must be a bare `.gif`/`.jpg` filename), and every non-SCT camera carries its real owner as a `credit` shown beside the shared `provider`. The feed carries no compass heading, so every camera loads at low heading confidence (same as TfL and Fintraffic). SCT's own feed link (`RenderService`) needed a workaround: it always 302s to a second endpoint (`TransitCamera`) on a Location the upstream hardcodes as plain http even when requested over https — refused by `fetchWithinHost`'s same-origin (scheme-included) redirect policy — and separately, `mct.gencat.cat`'s TLS setup fails the handshake with Node's fetch outright (`ERR_SSL_WRONG_SIGNATURE_TYPE`) even though other HTTP clients complete it. The loader therefore builds the `TransitCamera` URL itself, over plain http, from `RenderService`'s `sctidcam` id, rather than registering the (broken) upstream link — the only transport this one host actually serves to this runtime. Camera ids are built from the SCT camera file or the partner image path, not the feed's `fid` (which embeds an upstream server-start stamp and changes on every upstream restart), and rows the feed lists more than once collapse to one camera. The feed carries no camera status field, so a camera its publisher has taken offline still registers and shows the publisher's own "image unavailable" still (SCT and Barcelona both serve one with HTTP 200), the same as other packs without a status field. Frames are fetched at request time and never stored or redistributed. The feed itself states no licence; the pack relies on the Generalitat de Catalunya open-data portal's terms for this dataset (the licence and attribution above). Disable with `CCTV_CATALONIA_ENABLED=0`.
 - **King County road cameras.** Keyless. The camera list is one public ArcGIS FeatureServer GeoJSON query (King County DOT Road Services, "King County and WSDOT Traffic Cameras"). The `outFields` list is explicit on purpose: the layer also carries asset-administration columns — including staff names — that are never fetched. Only live, active cameras with frames on the county's own `info.kingcounty.gov` image handler are registered (the feed writes `http://`; the handler serves HTTPS, so URLs are upgraded and pinned before registration). WSDOT-owned rows in the layer are skipped because their frames are WSDOT-hosted, outside the pinned image origin; partner-city cameras hosted on the county image handler (e.g. Newcastle) name their owner as the per-camera credit. The layer publishes no facing, so headings use the shared id-hash fallback at low confidence. Uniquely, the county publishes each camera's hardware `Manufacturer`/`Model` (Cohu 3950/3965, Bosch AUTODOME, Axis PTZ domes); both are carried on the source (and served by `/api/cctv/sources`) as `model` and `manufacturer` for identified-hardware consumers (vendor-generic strings such as `PTZ` name no model and are omitted). Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_KINGCOUNTY_ENABLED=0`.
 - **WSDOT highway cameras.** Keyless. The camera list is the Esri JSON layer `data.wsdot.wa.gov/travelcenter/Cameras.json` — the same layer WSDOT's own Travel Center map consumes (~1,700 point features, EPSG:3857 geometry converted to WGS84 on load; the body carries Windows-1252 bytes and is decoded as such). Only frames on WSDOT's own `images.wsdot.wa.gov` host are registered — the catalog also lists ~70 partner cameras (Oregon DOT, City of Seattle, lodges, airports) whose own terms apply, and those are skipped rather than proxied. WSDOT's layer metadata marks the feed for "low volume" use (see WSDOT's [travel information disclaimer](https://wsdot.wa.gov/about/policies/travel-information-disclaimer)). The catalog is fetched once per CCTV catalog refresh (every 15 minutes), and a camera's frame is fetched only when that camera is viewed; frames are never stored or redistributed. The live feed's `CompassDirection` is a single cardinal (N/E/S/W), `B` (both directions — most rows), `O`, or null. A single cardinal gives a high-confidence heading (the diagonals NE/SE/SW/NW are mapped too should they appear); `B`, `O`, null, and any other code carry no single facing and use the shared id-hash fallback at low confidence. By default the 250 cameras nearest Seattle and Spokane load; `CCTV_WSDOT_MAX_SOURCES` changes the cap (8–1,200) and `CCTV_WSDOT_ENABLED=0` turns the pack off. A keyed WSDOT Traveler Information API serves the same population for higher-volume use and is deliberately not required here.
+- **Hong Kong Transport Department traffic snapshot cameras.** Keyless. The English camera list is the public DATA.GOV.HK XML at `static.data.gov.hk/td/traffic-snapshot-images/code/Traffic_Camera_Locations_En.xml`; frames are stills on `tdcctv.data.one.gov.hk`, and only that host is registered. Frame URLs are rebuilt from each camera key (`https://tdcctv.data.one.gov.hk/{KEY}.JPG`) rather than taken verbatim from the catalog. Stills were probed to answer directly on that origin with no redirect hop. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. By default nearly the full catalog loads (~1,013; pack cap 1,100), prioritized nearest Central, Tsim Sha Tsui, Sha Tin, Tsuen Wan, Tai Po, Fanling, Tuen Mun, Yuen Long and Tseung Kwan O so a lowered cap still spans Hong Kong Island, Kowloon and the New Territories. When the sum of packs exceeds the catalog-wide ceiling, shared round-robin keeps every lane represented. `CCTV_HK_MAX_SOURCES` (8–1200) changes the cap and `CCTV_HK_ENABLED=0` turns the pack off. The DATA.GOV.HK Terms of Use require attribution to the Government / Transport Department / DATA.GOV.HK.
 - **Statens vegvesen road cameras.** Keyless. The camera list is one GeoJSON request to the OGC API Features view of the official DATEX 3.1 CCTV site table (`ogckart-sn1.atlas.vegvesen.no/ogc/features/v1/collections/datex_3_1:CctvSimple/items`), so no DATEX account is needed; frames are stills on `kamera.atlas.vegvesen.no/api/images/<cameraId>`, and only that exact path per camera is registered. Cameras the feed reports as faulty are dropped. About 135 working cameras also publish live HLS (`kamera.vegvesen.no/public/<cameraId>/manifest.m3u8`, MPEG-TS); those play as live video through the bounded in-memory HLS relay, with the still as the snapshot fallback, and only that exact manifest path per camera is registered. `CCTV_VEGVESEN_VIDEO=0` keeps every camera on stills. `orientationDescription` names the place a camera faces, not a bearing, so it goes into the label and headings use the id-hash fallback at low confidence. By default every live camera loads (~850); `CCTV_VEGVESEN_MAX_SOURCES` (8–1000) lowers the cap, keeping the cameras nearest Oslo, Bergen, Stavanger, Trondheim, Kristiansand, Bodø and Tromsø and `CCTV_VEGVESEN_ENABLED=0` turns the pack off. Frames are fetched at request time and never stored or redistributed. The NLOD attribution is registered in the Data attribution popover.
+- **Kartverket ground heights for Statens vegvesen cameras.** The camera feed's points are 2D, so the loader asks Kartverket's keyless point-height API (`ws.geonorge.no/hoydedata/v1/punkt`, CC BY 4.0) for the terrain height at each camera. Requests carry 20 points: the API accepts 50, but above ~20 it answers the extra points from contour lines (`hoydekurver`, metres to ~20 m off) or not at all. Eight requests run at a time, about 36 for the whole country: a cold lookup took 6–13 s in testing (single requests 0.6–9.5 s). Answers are matched by the coordinates the API echoes and recorded only for points that request asked about. Over water the API returns the sea-floor depth (`dybdekurver` or `Havflate`), which is replaced by 0 m, the water surface; for the ~14 bridge cameras that is below the deck, but much closer than the sea floor or the flat prior. Heights are cached in memory by position for the life of the server, and points with no height (a few ferry quays and bridges, or a point a 200 answer leaves out) for 6 h, so the 15-minute catalog refresh only asks about new or moved cameras. The first failing request (a 408, 429 or 5xx, a network error, a request over 10 s, or an unreadable or oversized body) stops the lookup, with no retries, and no new lookup starts until the backoff ends (Retry-After when sent, else 30 min, longer than the refresh; bounded to 1 min–1 h). Any other 4xx marks that request's points as having no height and the lookup carries on. The whole lookup has a 30 s deadline; a lookup cut short by it resumes on the next refresh without a backoff. The lane waits at most 12 s, counted from the start of the loader, and only when more than 10% of the cameras have no answer yet; a few new cameras or expired misses are looked up in the background. A slower lookup keeps filling the cache, and the cameras it had not reached keep the flat prior until the next 15-minute refresh (about 190 of 865 on one slow first run). Only coordinates are sent, with the same User-Agent as the other CCTV requests. `CCTV_VEGVESEN_HEIGHTS=0` turns the lookup off. The Kartverket credit, with a note that heights over water are set to 0 m and heights are rounded to 0.1 m, is shown beside the Statens vegvesen entry in the Data attribution popover.
 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `[email protected]` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
 - **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. (2) The server-side `/api/terrain/heights` proxy (disk-cached, serve-stale) resolves per-point ellipsoidal ground height for entity placement. Both are best-effort with a keyless-safe fallback (bundled EGM96 geoid math) if Re:Earth is unreachable.

 Keep the `env`: bash treats `UID` as read-only, so a plain `UID=1026` in front of a command is silently ignored. If the container can't write the checkout, it says so at start. Docker Desktop on macOS and Windows maps ownership for you.
 
+On SELinux hosts (Fedora, RHEL), compose mounts the checkout with `:z` so the container may read it; Docker may relabel the checkout for container access, which can take a moment on a large checkout. Without that, the start fails with `Cannot find module '/app/scripts/docker-start.mjs'`.

 Behind a reverse proxy, put your keys in `.env` or pass them as environment variables - Provider Settings refuses proxied requests on purpose - and add the hostname you serve it on, for example `GEV_ALLOWED_HOSTS=globe.example.lan` (see [Sharing an instance](#-sharing-an-instance)).

+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.

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.

+# Share-link format
+
+A share link restores a view: where the camera is, what it follows, the visual
+style, data layers and panel layout. There are two forms.
+
+- **Long form** — `#v=2&lat=30.2672&lon=-97.7431&…`. Parsed by
+  `src/sharelink.js`. The address bar follows the live view in this form, and
+  links already in the wild keep working; the long form is never removed.
+- **Short form** — `<app>/share/<code>`, where `<app>` is wherever the app is
+  served (an origin's root, or a base path) and `<code>` is encoded and
+  decoded by `src/share/viewCodec.js`, which is pure (no DOM, no Cesium) and
+  needs no server. Hosts import it as `@gods-eye-view/core/share/view-codec`
+  (a server can read a code to describe the view in a link preview). The share button makes this form. The same code opens on
+  any copy of the app. `src/share/shareLinkPath.js` reads and builds the
+  address, and `src/share/legacyShareState.js` converts between the long
+  form's parsed state and the code's state.
+
+The same view in both forms (a real session's link):
+
+| Form  | Characters        |
+| ----- | ----------------- |
+| Long  | 302 (the hash)    |
+| Short | 39 (the `<code>`) |
+
+For example, a camera-only place view is a 24-character code (31 with its
+created-at time).
+Following an aircraft is 42–50: 42 when the link is made from the app's own
+follow camera with the fix taken as the link is made, 44 with a fix four
+seconds older, and 50 after orbiting to another heading and pitch. A view in
+any other style that keeps the style's own look adds only the style (two
+bytes): the 42-character followed aircraft in Noir is 44.
+
+## Opening a short link
+
+At start-up the app reads `<code>` from an address whose path ends in
+`share/<code>` (a host can pass the code instead, as `initialShareCode` to
+`createApplicationControls`). A code that decodes runs the same restore as a
+long link; once the app next writes the address, `/share/<code>` is replaced
+by the app's own address and the long form, without a new history entry, so
+a reload follows the live view. A code that is rejected restores nothing: the
+app starts as usual and says the link can't be opened.
+
+A thing view turns on its entity's layer and follows the entity by id, using
+the same restore as a long link's followed flight or satellite (and its
+expiry windows); a vessel is selected once the vessel feed has it. Opening is
+best effort: until the entity is found, and if it is not found in time, the
+camera is where the link was made, looking at the entity's last-known fix,
+and the app says that the entity isn't reporting and when the fix was taken.
+The share button makes a thing view while the camera follows an aircraft,
+military aircraft or satellite. A selected vessel is not followed (the camera
+stays where the user puts it), so a link made then is a place view; vessel
+thing views open, but the app does not make them yet.
+
+## Payload
+
+The code is unpadded base64url (`A–Z a–z 0–9 - _`). The decoded bytes are:
+
+1. one **version byte**, currently `1`;
+2. a sequence of **fields**, each a varint tag `field_number << 3 | wire_type`
+   followed by its value;
+3. one **check byte**: the CRC-8 of everything before it.
+
+| Wire type | Value                                                       |
+| --------- | ----------------------------------------------------------- |
+| 0 varint  | unsigned LEB128, at most 8 bytes, at most 2^53 − 1          |
+| 1 fixed64 | 8 bytes (not used by v1; skipped)                           |
+| 2 LEN     | varint length, then that many bytes (text or a sub-message) |
+| 5 fixed32 | 4 bytes (not used by v1; skipped)                           |
+
+Signed values are zigzag varints (0, −1, 1, −2 → 0, 1, 2, 3). Text is printable
+ASCII. Fields are written in ascending order; the decoder accepts any order.
+
+A field whose value equals its default is **omitted**. The decoder fills every
+omitted field from the same defaults table the encoder reads (for a
+style-dependent field, the decoded style's defaults), so an empty
+payload (code `AQc`: the version byte and its check byte) is the all-default
+view.
+
+### Check byte
+
+The check byte is CRC-8 with polynomial x⁸ + x² + x + 1 (`0x07`), initial
+value 0, no reflection and no final XOR (CRC-8/SMBUS; the check value of the
+ASCII digits `123456789` is `0xF4`). A decoder that computes a different value
+rejects the code (`checksum`) before reading any field, so a mistyped code
+never opens a different view. A degree-8 CRC catches every error burst of up
+to 8 bits; one base64url character is 6 bits, so **every single-character
+typo is rejected** (a test tries every substitution at every position). Two
+swapped neighbours, a dropped or an extra character are caught with a
+probability of about 255 in 256 (many of them already fail as base64url).

+Field 1 absent means `thing` when field 13 is present and `place` otherwise,

+
+Enum codes are the list position (0, 1, 2…). A name not in the list is written
+as LEN text in the same field, so the app can add a style or map before this
+table learns its code. A new style's settings are encoded against its own
+defaults, while a decoder that does not know the style uses Normal's; adding a
+style also extends the pinned style-defaults table.
+
+Flag bits (field 9): 0 `bloom`, 1 `sharpen`, 2 `hudVisible`, 3
+`celestialRing` (each defaulting by style), 4 `scopeEnabled` (default on).
+
+### Style defaults
+
+A default marked **style** is what the view's style applies when it is
+selected in a fresh session (`SHARE_VIEW_STYLE_DEFAULTS`): the app's
+first-load baseline (`GLOBAL_POST_DEFAULTS` in `src/ui/visualPresets.js`),
+with the style's preset on top (`STYLE_PRESET_DEFAULTS`), and the style's
+shader parameters at the preset's values, else the shader's own. The encoder
+compares against the defaults of the view's style, and the decoder fills
+omitted settings from the defaults of the style it decoded (an unknown style
+uses Normal's). So a view that keeps its style's look costs its camera and
+style alone. (A recipient-side preference the app remembers, such as the
+detection allocation, is not a style default: a sender who changed it pays
+for it.) In v1:
+
+| Setting                   | Every style   |
+| ------------------------- | ------------- |
+| bloom, intensity          | off, 0        |
+| sharpen, intensity        | on, 49        |
+| HUD visible, variant      | on, tactical  |
+| detection mode, density   | DENSE, 75     |
+| allocation, fade, outside | ELASTIC, 7, 1 |
+| celestial ring            | off           |
+
+| Style        | Shader parameters (field 27 defaults)                           |
+| ------------ | --------------------------------------------------------------- |
+| normal       | none                                                            |
+| retro        | pixelation 1, distortion 0, instability 0.42                    |
+| surveillance | gain 0.18, bloom 0.22, scanlineStr 0.96, pixelation 1           |
+| thermal      | sensitivity 0.85, bloom 0.2, mode 0.33, pixelation 1, palette 0 |
+| anime        | saturation 1, edgeThick 0.5                                     |
+| noir         | contrastAmt 1.2, grainAmt 0.5, vignetteAmt 0.5                  |

+
+These are frozen like every other default: the codec reads them from the
+app's tables today, and a test pins them, so if a table moves the old values
+are frozen in the codec rather than changing what shared links mean.
+
+### Precision
+
+| Value                       | Stored as                 | Matches the long form |
+| --------------------------- | ------------------------- | --------------------- |
+| Latitude, longitude         | 10⁻⁴ degree (about 11 m)  | `toFixed(4)`          |
+| Altitude, range             | whole metres              | `Math.round`          |
+| Heading, pitch, roll        | whole degrees             | `Math.round`          |
+| Intensities and percentages | integers                  | `Math.round`          |
+| Style parameters            | hundredths after clamping | `sp` (× 100)          |
+| Created-at and observed-at  | whole seconds             | `at`                  |
+
+Angles: heading and roll are normalized into [0, 360) — the long form can
+write `roll=360` for a camera at 359.6°, which the compact form stores as 0 —
+and written as the nearer signed turn, so 350° costs one byte (−10).
+When a state is encoded, out-of-range input is clamped (latitude, pitch) or
+wrapped (longitude). A payload that stores a latitude or longitude beyond
+±90/±180 cannot come from the encoder and is rejected.
+
+### Layers (fields 10 and 11)
+
+A layer's number is derived from its permanent layer-state token
+(`src/data/layerStateTokenReservations.json`): a one-character token is its
+index in `0–9a–z`, a two-character token is 36 + first × 36 + second. The
+token ledger never reassigns a token, so layer numbers never change and new
+layers need no change here.
+
+Field 10 is a bitset: bit _n_ of byte ⌊n/8⌋ (least significant first) is set
+when layer _n_ is on. Present-but-empty means "every layer off"; an absent
+field leaves the recipient's layers alone (the long form's `l=` versus no `l`).
+A thing view's entity layer is always on, so its bit is not written: in a
+thing view, present-but-empty means "only the entity's layer", and an absent
+field opens with only the entity's layer on (the app writes the field
+whenever it has a layer set).
+
+Field 11 repeats `(layer number, option key, value)` for each option that
+differs from its frozen absent meaning (`SHARE_VIEW_LAYER_OPTION_ABSENT`). The
+option key is `option token index × 2 + kind`: kind 0 means the value is a
+zigzag varint (an option whose long-form spelling is a canonical integer),
+kind 1 means a varint length and ASCII text (the long-form spelling). Values
+are decoded by the layer-state codec's own option decoders.
+
+A followed aircraft, military aircraft or satellite is a thing view in the
+compact form, not a tracking option: the encoder moves it out of the layer
+options, and the converter moves it back for the long form.
+
+### Panels (field 12)
+
+Each entry is one varint: `panel number × 16 + collapsed × 4 + pinned`, where
+collapsed and pinned are 0 (no value), 1 (false) or 2 (true). Only panels that
+differ from the frozen default layout are written, plus a collapsed-0 entry
+for each panel the state has no opinion about (an older long-form link that
+predates the panel); a panel with no entry takes its default. Values of 3 are
+reserved: a decoder ignores that entry, as for collapsed 0.
+
+| #   | Panel                  | Long-form token | Default             |
+| --- | ---------------------- | --------------- | ------------------- |
+| 0   | `control-panel`        | `c`             | collapsed, unpinned |
+| 1   | `location-bar`         | `l`             | collapsed, unpinned |
+| 2   | `data-panel`           | `d`             | collapsed           |
+| 3   | `cctv-panel`           | `v`             | collapsed           |
+| 4   | `recent-imagery-panel` | `i`             | expanded            |

+### Style parameters (field 27)
+
+Pairs of varints `(token index, value × 100)` for the parameters of the
+view's style that differ from its defaults, using the long form's `sp` tokens
+(`SHARE_VIEW_STYLE_PARAMS`). The decoded state always lists every parameter
+of the style: the stored ones over the style's defaults. A long link without
+`sp` converts to the style's defaults.
+
+## View kinds
+
+A **place** view (field 13 absent) opens at its camera, fields 2–7.
+
+A **thing** view (field 13 present) follows an entity. Field 13 is a
+sub-message:
+
+| #   | Field       | Encoding                                                 | Default |
+| --- | ----------- | -------------------------------------------------------- | ------- |
+| 1   | aircraft    | entity id: varint (24-bit ICAO address) or LEN text      |         |
+| 2   | military    | entity id: varint (24-bit ICAO address) or LEN text      |         |
+| 3   | vessel      | entity id: varint (MMSI) or LEN text                     |         |
+| 4   | satellite   | entity id: varint (NORAD catalog number) or LEN text     |         |
+| 5   | range       | uint metres from the entity to the camera                | 2000    |
+| 6   | heading     | angle, the camera's heading while following              | 0       |
+| 7   | pitch       | sint whole degrees, the camera's pitch while following   | −35     |
+| 8   | fix lat     | coord, the entity's last-known latitude                  | none    |
+| 9   | fix lon     | coord, its last-known longitude                          | none    |
+| 10  | fix alt     | sint metres                                              | 0       |
+| 11  | fix age     | sint seconds the fix predates the created-at time        | 0       |
+| 12  | observed-at | epoch, when the fix was taken; only without a created-at | none    |
+
+The entity kind is the field that carries the id (its code in
+`SHARE_VIEW_ENTITY_KINDS`), so it costs nothing; exactly one of fields 1–4 is
+present (two is malformed). Entity ids are the ones the layers look up: an
+aircraft's ICAO 24-bit address (six hex digits, stored as a number; other
+forms such as TIS-B `~abc123` as text), a vessel's MMSI and a satellite's
+NORAD catalog number (decimal numbers; an MMSI with a leading zero stays
+text). Ids are lowercase and match `[0-9a-z~_-]{1,16}`.
+
+Fields 5–7 are the follow offset: the camera looks along (heading, pitch) at
+the entity from `range` metres away, heading clockwise from north, in the
+entity's local east-north-up frame. The defaults match the app's own follow
+camera, which looks north at about −35°, so only its range is written.
+
+Fields 8–12 are the last-known fix, the entity's position when the link was
+made. Fields 8 and 9 are both written whenever there is a fix; their presence
+marks it. Its time is the created-at time (field 8 at the top level) minus
+field 11, or field 12 when the view has no created-at time.
+
+**The camera of a thing view with a fix is derived, not stored**: fields 2–7
+are not written, and the camera is where following the fix from the offset
+puts it (`followCameraFor` in `src/share/follow.js`): the camera sits
+`−r·cos p·sin h`, `−r·cos p·cos h` and `−r·sin p` metres east, north and up
+of the fix (heading h, pitch p, range r), on a sphere of radius 6 371 000 m,
+and looks back at the fix (its heading and pitch are those of that direction
+at the camera, roll 0; at follow distances they equal h and p). A
+decoder ignores fields 2–7 when the fix is present. A thing view without a
+fix (one converted from a long link, which records neither offset nor fix)
+writes its camera in fields 2–7 like a place view.
+
+A decoder that meets a view kind or an entity kind it does not know (an id in
+a thing field it skips) opens the view as a place at its camera — the derived
+one when there is a fix — and reports `fallback`.
+
+## Decoding rules
+
+`decodeShareView(code)` takes the bare code and never throws. It returns
+`{ ok: true, state, unknownFields?, fallback? }` or `{ ok: false, reason }`.
+
+Rejected (the whole link): input over 2048 characters, bad base64url
+(padding, foreign characters, impossible length, stray bits), fewer than two
+bytes, a check byte that does not match (`checksum`), an unknown version byte,
+a truncated value, a varint over 8 bytes or above 2⁵³ − 1, an
+overlong varint, a LEN longer than what remains (at any level, including
+inside the thing sub-message), a reserved wire type, field number 0, a known
+field with the wrong wire type or repeated, two entity ids in one thing, a
+duplicate panel/option/style entry, non-ASCII text, and a latitude or
+longitude (camera or fix) beyond ±90/±180.
+
+Tolerated and reported in `unknownFields`: unknown fields at any level
+(skipped by wire type), unknown enum codes and names (the default is used),
+unknown flag bits, layers, panel values and style parameters, and layer
+options the layer-state codec rejects or that are filed under a layer other
+than their owner. Detection mode and allocation names outside their lists
+fall back to the default rather than reaching the long form's lenient
+migration. The map stack and HUD variant are open: a name outside their lists
+that matches `[A-Za-z0-9_-]{1,32}` is kept as written (the app decides what
+it means) and is not reported; only a name outside that grammar is. A
+created-at time in the future is dropped, as the long form's `at` is.
+
+## Changing the format
+
+These rules keep every link that was ever shared working, in every version of
+the app that can open it.
+
+1. **Field numbers are permanent.** Never renumber, never reuse. A field that
+   is no longer written stays in `SHARE_VIEW_FIELDS` marked `retired: true`.
+2. **A field's type and wire type are permanent.** To change one, add a new
+   field.
+3. **Defaults are frozen meanings.** A default is what an omitted field meant
+   when links were written. If the app's default moves, leave the table alone:
+   the encoder will start writing the new value explicitly. Style defaults
+   are read from the app's style tables; when those move, freeze the old
+   values in the codec (see Style defaults). The same applies
+   to `SHARE_VIEW_LAYER_OPTION_ABSENT` and the panel defaults.
+4. **Codes are append-only.** Enum lists, entity kinds, flag bits, panel
+   numbers and style parameter tokens only grow.
+5. **Add, don't change.** A new setting takes the next free field number
+   (28 onwards; fields 1–15 have one-byte tags and are all taken). A new
+   boolean takes the next flag bit instead, which costs nothing when it is at
+   its default.
+6. **New view kinds and entity kinds** get the next code. A new entity kind's
+   id takes the next free thing field (13 onwards), so older apps skip it and
+   fall back to the camera. A thing that needs more than an id (for example a
+   CCTV camera, a radio station or a transit vehicle) adds further thing
+   fields the same way.
+7. **A new layer option** needs an entry in `SHARE_VIEW_LAYER_OPTION_ABSENT`
+   (a test fails until it has one).
+8. **Bump the version byte only** for a change older decoders must refuse.
+   Decoders reject any version they do not know. The trailing CRC-8 check
+   byte belongs to every version.
+9. **Derivations are frozen too.** `followCameraFor` and the follow-offset
+   defaults are part of the format: changing them moves the camera of every
+   thing link already shared.
+
+Add a test for every change: a round trip, and a payload written with the new
+field that the previous decoder still reads.

+## 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.
+
+## Plurals
+
+`Intl.PluralRules('zh-CN')` has one category, `other`: a `tn()` entry has only that form. Use a measure word next to the number where Chinese needs one: 「{count} 个密钥」, 「{count} 架飞机」, 「{count} 艘船」.

-## Rehearse
-
-Run the beats once on the presenting Mac before the meeting. On first load the keyless terrain host can be slow; if a close-up stays black for more than a few seconds, the engine falls back to flat terrain on its own.
-
-Refresh the bundled data while `npm run dev` is running: `node mobile/demo/capture-snapshot.mjs --base http://localhost:4173` for the snapshot, and `node mobile/demo/capture-history.mjs --base http://localhost:4173 --minutes 150` for the recording (it writes every 5 minutes; behind a proxy, prefix it with `NODE_USE_ENV_PROXY=1`).

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

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

-
-Thumbnails use the keyless Esri World Imagery `export` endpoint for the situation's bounding box, so every card shows the real place.

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

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

-| 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.

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

-
-Rasters are drawn a few kilometres above the ground and unlit, so storms stay visible on the night side. When an upstream is down, the layer reports `status: 'error'` with a `message`.
-
-When a weather layer is on, `layers()` entries can also carry `frames` (the number of frames available) and a `message` that gives the product title and the frame age.
-
-When NHC has published an advisory but its cone geometry is still pending, the cyclone layer and cards take the forecast positions from the advisory text, so a track is still drawn but there is no cone.

-## Dev harnesses
-
-- `mobile/globe/dev.html` shows the globe full-screen and exposes `window.globe`. Its labels show `detail`.
-- `mobile/globe/contact.html` is the contact sheet: it calls `situations()`, then `thumbnail()` for every card.
-  - `?lat=&lon=` sets the viewer.
-  - `?only=cyclone,eye` filters cards by id prefix.
-  - `?w=330` sets the card width.

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

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

-## Entities and dossiers
-
-```js
-globe.entity(ref) → Promise<Dossier>   // ref: entity id string, a 'pick' payload, or { kind, id }

-globe.graph(ref) → { center, nodes: [{ id, kind, title }], edges: [{ from, to, relation }] }   // ≤ 40 nodes, sync
-```
-
-Kinds: `aircraft`, `helicopter`, `military`, `satellite`, `vessel`, `quake`, `camera`, `situation`, `place`, `moment`, `track`, `capture`. There are never person entities. Aircraft dossiers wait at most 2.5 s for the server track (aircraft identity comes from adsbdb, 3.5 s budget).
-
-## Reactions and attention
-
-```js
-globe.react({ lon, lat, kind: 'heart'|'fire'|'eyes'|'wow', count = 1, altM = 0 }) → number
-globe.attentionHeat(points | null)    // points: [{ lon, lat, weight? }]; soft glow where viewers are
-```
-
-Reactions draw on a screen-space canvas that the globe owns (`.gev-reactions`, pointer-events none, above the globe and below your HTML). Each glyph stays anchored to its point as the globe moves. At most 300 are alive at once, and the canvas animates only while some are alive.
-
-## Your sky now

-globe.skyNow({ lon, lat } = viewer) → Promise<{

-`mobile/globe/dev.html?moment=empire-state&speed=30` plays a Moment on load and prints its events in the HUD. `globe.debug` exposes `{ recorder, detector, stage, ghosts }` for tests. It is not part of the contract.
-
----
-
-# Polish round
-
-Additive. Nothing above changes.
-
-## Bundled recording (the time machine always has ghosts)
-
-`mobile/demo/history/{nyc,london,gulf}.json` hold a real recording of every aircraft over the New York area, London and the North Sea approaches, and the Gulf of Mexico, captured by `node mobile/demo/capture-history.mjs` (adsb.lol point snapshots around each region's anchors, the dev server's `/api/flights` and `/api/military` as fallbacks; one fix per 30 s below 6 km, per 120 s in cruise). Positions are quantised to 1e-4° and 10 m and delta-encoded (`format: 'gev-history/1'`). Timestamps are the true capture times and are **never shifted**: the time machine shows the recording where it happened.
-
-The engine loads it about 5 s after the first frame into a second recorder (no expiry) and reads both through one view: ghosts, `setTime` history mode, `entity()`, `trackOf()` and `search()` see the recording; on a key present in both, the device's own recorder wins.
-
-```js
-globe.history().archive → { start, end, regions: [{ id, label, bbox, source, start, end, tracks,
-                            busiest: { t, aircraft } }] } | null
-globe.loadHistory()     → Promise<history().archive>          // resolves once it is loaded
-globe.historyNear(t, lon, lat, km = 100)
-  → [{ id /* entity id */, key, kind, title, lon, lat, altM }]  // recorded contacts at t, nearest first
-// event 'history' → history(), once the recording is loaded
-```
-
-The time ribbon shades the recording in teal (`RECORDING · 23 OCT`) next to the device's own `RECORDED` range, and its readout names the day when the playhead is on another UTC day.
-
-## Camera
-
-```js
-globe.flyTo({ lon, lat, height, heading, pitch, eye: true }); // eye: lon/lat/height place the camera itself
-```
-
-## Night close-ups
-
-Below ~400 km, where Cesium's lighting is faded out, a night-side view grades the Esri mosaic toward night (darker, desaturated, slightly cooler) with a soft glow of the real Black Marble lights above ~40 km; the strength follows the sun's elevation under the camera at the **scene clock**, so a Moment keeps the lighting of its own time (the hero is daylight). A terrain watchdog falls back to the flat ellipsoid when the keyless terrain host stalls (the globe would otherwise show only the star field).
-
-## Dossiers
-
-`privacy` is set only for real privacy programmes (`'pia'`, `'ladd'` flags). An airframe with no public registry record gets `registryMissing: true` instead, and `identity.operator` falls back to the callsign's ICAO airline prefix (`mobile/globe/airlines.js`, about 150 operators).
