Keep the cockpit camera steady near the ground on both engines

Cesium lifts a camera below its globe every frame, between the cockpit's 20 Hz updates, so an eye placed under the terrain (an aircraft reading below it on a cold floor cell) jumped up and down. The cockpit now also keeps its eye above the engine's own surface. Navara's ground floor stands aside while the camera inputs are off, since the cockpit places the camera itself.

 - **Houston TranStar cameras.** Keyless. The camera list is the public `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js` catalog (~1,000 cameras across Greater Houston); frames are stills at `www.houstontranstar.org/snapshots/cctv/<id>.jpg`, synthesized from a validated numeric id rather than taken from the payload, and only that host is registered. Cameras whose catalog id is `0` (a different, non-snapshot class) and cameras outside Greater Houston are dropped. TranStar's `dir` field is the side of the freeway the camera sits on, not the way it faces: TranStar's own map shows it as "Traffic closest to the camera is traveling …" (South → eastbound, North → westbound, West → southbound, East → northbound). That travel direction (90°, 270°, 180°, 0°) seeds the heading as a low-confidence prior with the low-confidence pose; `None` or an unknown value uses the shared id-hash fallback at low confidence. Headings are corrected with the in-app calibration gizmo. Off by default. TranStar's [Content Usage terms](https://traffic.houstontranstar.org/disclaimer.aspx) prohibit copying or distributing the site's information, and external framing or linking to specific images, without TxDOT's prior written permission; its FAQ grants permission-free use only for the RSS feeds. This project does not hold that permission for downstream installations, so the pack loads only when an operator who holds TxDOT's written permission sets `CCTV_HOUSTON_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to TranStar. Once enabled, it loads the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and Galveston; `CCTV_HOUSTON_MAX_SOURCES` (8–400) changes the cap. Snapshots update about every 3 minutes, which is also the ambient still cadence. Frames are fetched from TranStar and relayed to the browser on demand, buffered only transiently per request, sent with `Cache-Control: no-store`, and not archived.
 - **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_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 eighteen registered feeds, covering seventeen 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, YRT and Rio’s SMTR 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.
+- **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.

 - **Radio country coverage (optional).** Set `RADIO_PRIORITY_COUNTRIES=IN,PL` in the local `.env` and restart to include stations beyond the global click charts. The operator may choose up to eight unique ISO alpha-2 country codes; no key is needed. Each country adds one bounded query (at most 200 rows) and reserves up to 40 unique, usable stations inside the existing 750-station catalog. Country seeds precede specialist-tag seeds and global popularity fill; unused slots return to the shared pool. This is a coverage preference, not an exhaustive national directory or a guarantee of stations in every city. Countries with no eligible HTTPS MP3/AAC geolocated stations remain empty. An unset list preserves global selection. Country requests share the directory cache and three-worker pool; failed country queries are reported in coverage without blocking a healthy global refresh. Failed/degraded refreshes back off for one minute, with at most three mirrors per query.
 
 - **Radio Browser.** In every installation, including when `RADIO_PRIORITY_COUNTRIES` is unset, each request tries at most three mirror candidates (later fallback candidates are skipped), and failed or partial catalog refreshes back off for 60 seconds. A cold-start failure therefore continues returning 503 during that delay even if upstream recovers. `/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; broad/specialist responses whose rows all fail the product's health policy do not count as successful queries. Optional priority-country outcomes are advisory: valid, in-limit responses with no eligible stations succeed as empty results, while failed or malformed country queries report unsuccessful coverage without degrading the global catalog. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty broad/specialist payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. 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.

 - **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.
 - **OSRM on the FOSSGIS routing servers.** Keyless (no API key). Every route is requested by a person: clicking A and B in the Directions layer, or a voice "route from A to B". The server-side `/api/route` proxy sends an identifying `User-Agent`, pins the upstream host, accepts 2-12 coordinates, rejects any leg over 600 km or a total over 2,500 km, caps the buffered response at 8 MB, times the upstream out at 12 s, rate-limits per client, caches each route for 10 minutes, and coalesces identical requests that are in flight at the same time. Turn-by-turn maneuvers are asked for only when a caller wants them (`steps=1`), so the callers that do not read them send the smaller request. The "fix the map" link the policy asks for is in the Data attribution popover beside the OpenStreetMap credit.
 - **FAA Special Use Airspace.** Keyless. `/api/drone-airspace` queries the public FAA AIS FeatureServer for prohibited (P) and restricted (R) zones only — not MOAs, TFRs or other SUA types — with simplified geometry, a body cap, paging, a one-hour cache and stale-on-error. The layer is US coverage, informational only, and is not a substitute for B4UFLY, LAANC or a preflight briefing. Data is fetched at request time and never stored or redistributed. US government public domain; courtesy attribution is registered in the Data attribution popover.
-- **iNaturalist.** Keyless. `/api/inaturalist/observations` returns cached random view samples (newest first globally), at most 200 per request. Recency uses observation time: the v1 `d1` filter and a rolling 48 h cutoff (whales 7 d); date-only rows qualify when their day starts within the window. Observation caches last 5 min (global 10 min), with stale fallback ≤1 h. `/api/inaturalist/grid` supplies density counts, cached 15 min. Both share a paced queue capped at 60/min and 8,000/day; only request counters persist in `.gev-cache/`. The server caches projected records, never raw responses. Private records are excluded; obscured coordinates become 0.2° cells. Observer identity is retained only for photo attribution. Eligible photos load directly from `inaturalist-open-data.s3.amazonaws.com`, with creator credit on ambient cards and creator/licence on selection. Per-record licences and noncommercial restrictions apply as listed above. Attribution appears in the layer row and Data attribution popover. Coverage follows community observations, not a census; Acartia adds Salish Sea marine mammals.
-- **iNaturalist grid (cell schema risk).** `/api/inaturalist/grid` shares observation-date, taxa, quality, pacing and budget rules with observations. A strict 64×64 UTFGrid schema guard fails closed; only logical-cell keys, counts and coordinates survive projection. Raw tiles, observation identifiers and free text are not retained. Projected tiles use a 400-entry LRU, 15-minute freshness and at most one hour of stale fallback. Views request at most six tiles; cached and adjacent-zoom coverage publishes before network waits, independently of observation pages. Cells supply a noninteractive density glow ranked within the view, from teal to amber with mono/CRT support. Every sighting badge comes from a real observation at its public position. Counts describe observations, not a population census. The endpoint is documented in the v1 and v2 API docs as “Grid Tiles UTFGrid” (`/grid/{z}/{x}/{y}.grid.json`), but its per-cell records are not specified; schema drift disables grids until revalidated. See `docs/KNOWN-ISSUES.md`.
-- **Acartia.** Keyless. `/api/acartia/sightings` reads the current 7-day marine-mammal feed for ALL, MAMMALS and WHALES views intersecting 45.5–50.5° N, 126–121° W in the Salish Sea. WHALES accepts recognized cetaceans; other identified marine mammals appear under ALL/MAMMALS. The server rounds positions to 0.01° and drops comments before caching projected records (10 min fresh, stale ≤24 h); raw responses are not retained. Selected text cards credit the reporting provider under CC BY 4.0 and show Be Whale Wise guidance. `/sightings/current` answers without a key today, but Acartia's README asks API users to create an account and generate an API key on the [Acartia dashboard](https://acartia.io/) and to follow its [community guidelines](https://acartia.io/register). Attribution also appears in the layer row and Data attribution popover. Opportunistic sightings, not a census.
 - **Mapped installations.** OpenFreeMap military polygons use a bundled Overture/OSM name index; wide views show named points. Optional operator-configured Overpass and explicit Google Places searches keep their own source paths. Mapped data does not establish current activity or complete coverage.
 - **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon (`PHOTON_URL`; unset uses the public instance, empty disables it), then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` and the voice outline route `/api/geocode/outline` share one Nominatim queue (`NOMINATIM_URL`; unset, empty and invalid values disable it; an operator must explicitly select an authorized endpoint): one request at a time at least 1.1 s apart, an identifying `User-Agent` and `Referer`, a short queue that refuses a burst, a pause after 429/403/5xx answers (honouring `Retry-After` in full), at most one retry after a network failure, and a per-install daily cap on public-instance requests (`NOMINATIM_DAILY_CAP`, default 50). Processes using the same installation state file hold one lock through the actual fetch invocation and recording the next public start, with the daily slot persisted before invocation; restarts share that count, spacing and any pause. An unfinished dispatch marker fails closed until operator recovery; it is never automatically reclaimed. Public access fails closed if the state file cannot be read, locked, written or semantically validated. This coordination does not span independent installations or state directories and does not establish an application-wide public-service allowance or authorize public use. An operator-selected non-public endpoint is outside the public cap, spacing and durable-state requirement; an upstream cooldown is kept with the endpoint that returned it rather than leaking across operator URLs. Answers are cached on disk (outlines 90 days, places 30 days, no-results 24 hours); failures are not cached. Outlines are looked up only for an explicit ask, after bundled data and any configured Overpass, and only results whose type suits the ask are used. Administrative outline responses expose country/admin-1/admin-2 identity only when the selected Nominatim row has a recognized, unambiguous address type consistent with its own name; numeric rank, ambiguous types, missing fields and contradictory names do not manufacture identity. It is not used for systematic or bulk queries.
 - **Street and building outlines.** Voice street highlights, pointed-at buildings and grounds use the OpenFreeMap vector tiles the traffic layer already loads. Traffic and outlines share one bounded pending fetch/decode owner per immutable XYZ tile; materialized outline geometry is charged to the retained-byte ceiling and capped by coordinate count. Consumer result caches and request lifetimes remain independent, while eviction or explicit teardown cancels queued idle projections and releases their decoded owner. No Overpass request is made unless `OVERPASS_UPSTREAMS` is configured. Named grounds require a returned name matching the selected place, except that an ask whose head noun names a kind of grounds (a school, university or college, hospital, cemetery, stadium or zoo) may use the part of the smallest unnamed tile area of that class that holds the resolved place; a differently named area never answers. Other anonymous landcover polygons cannot establish identity, so unsupported grounds stay unavailable rather than borrowing a nearby POI name.

-**Use.** Turn on **Street Level** under DATA LAYERS → Cameras, or with the pill in the STREET LEVEL panel header. Each provider has a chip in its own colour (Mapillary green), and one is lit at a time: lighting one switches the others off. Mapillary, which is free, is lit by default when its token is set; otherwise KartaView is. Zoom in to street level (below 60 km) for the coverage lines; from orbit the panel says to zoom in. The **IMAGERY** (ALL / 360° / FLAT) and **SINCE** filters apply to Mapillary, KartaView and Panoramax; Street View panoramas are all 360°, so with Street View lit the filters are hidden. Click a coverage line for its image cones and a cone to open the photo. Light **KARTAVIEW** (purple) and zoom in below about 6 km: its lines are the streets KartaView has photos of, and a click on one opens the photo nearest the click, flat or 360° (drag to look around), with cones along its drive; **‹ ›** or ← → step through the drive (Shift+← →, ↑ ↓ and + − look around a 360° photo; pinch zooms on a phone). Photos KartaView has archived are skipped, and where all are archived the panel says so. For KartaView, **SINCE** goes by upload date, as KartaView's own map does (it can filter by nothing else), and the panel notes it beside the SINCE value (ANY DATE (by upload date)); KartaView filters its lines on its own server, and a filtered area KartaView has not drawn before can take several seconds. Light **PANORAMAX** (orange) for the open, federated commons (strongest in France and Belgium): below about 60 km its lines are sequences. A click on a line opens that sequence's picture nearest the click without moving the camera, flat or 360°, with cones along the sequence around it; **‹ ›** or ← → step through it, and both filters apply. Its caption names the picture's authors (or the instance holding it) and licence (mostly CC BY-SA 4.0; pictures on the IGN instance are Licence Ouverte 2.0). On the **Google 3D** map (Google's terms keep Street View off other maps, where it does not appear), light **GOOGLE STREET VIEW** and click a street from below 3 km, or press **OPEN STREET VIEW** for the view centre, to open Google's panorama there; step along its arrows. Above the photo: **EXPAND** (full screen; Esc leaves) and **FIT / FILL** (Mapillary, and flat KartaView and Panoramax photos). The caption links to the image on the provider's site, and the globe credits each provider that is on ("© Mapillary contributors, CC BY-SA 4.0", "Street View imagery © Google", "© KartaView contributors, CC BY-SA 4.0", "© Panoramax contributors, licence per picture").

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 map routes (`/api/terrain/heights`, `/api/drone-airspace`, `/api/inaturalist/observations`, `/api/acartia/sightings`, `/api/overpass` and voice place search's `/api/osm/features`, which spends the same operator Overpass) use the same cross-site checks, minus the forwarding-header refusal: they guard only per-client quotas and caches, not a key or a bill, and the map and voice need them to work behind a reverse proxy. `/api/overpass` also admits at most 300 POSTs a minute per peer (IPv6 peers keyed by /64) and 900 a minute across all remote peers before it reads a body. A direct loopback request — a loopback socket with none of the forwarding headers `hasProxySignals` checks (`Forwarded`, `Via`, `X-Forwarded-For`, `X-Forwarded-Host`, `X-Forwarded-Port`, `X-Forwarded-Proto`, `X-Real-IP`, `CF-Connecting-IP`, `CF-Ray`) — draws on its own per-peer admission window, so remote peers cannot exhaust the owner's admission. A reverse proxy on the same machine must add at least one of those headers (Caddy and Cloudflare do by default; nginx needs `proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;`, plus `proxy_set_header Host $http_host;` and `proxy_set_header X-Forwarded-Proto $scheme;` so the `Origin` check matches), or its traffic is indistinguishable from the owner's and shares the owner's window. With one, its requests are then counted as remote, in one bucket per proxy socket — the forwarded client address is never trusted as identity — so all users behind one proxy share 300/min. The isolation needs a loopback socket: under the default Docker bridge network every host-side client, the owner included, arrives from the container gateway and is one remote peer. **Limit:** this isolates admission only. The upstream budget (90 requests/min per client key, 300/min across all clients) is shared, so once remote traffic has used the global upstream budget, an owner request that misses the cache can still get `429`, or `503` when remote misses hold every upstream concurrency slot; cache hits are unaffected. 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.

+- Package: `cesium` 1.138.0 (`@cesium/engine` 22.3.0); the files in `src/geo/`
+  are adapted from `@cesium/engine/Source/Core` (`Math.js`, `Ellipsoid.js`,
+  `scaleToGeodeticSurface.js`, `Cartographic.js`, `Cartesian2.js`,
+  `Cartesian3.js`, `Matrix3.js`, `Matrix4.js`, `Quaternion.js`,
+  `Transforms.js`) and say so in their first
+  line. The changes: the classes' static functions became module functions,
+  vectors, geodetic positions and quaternions became plain-data instances of
+  module-private constructors (own enumerable fields only, no methods),
+  matrices plain arrays, and the ellipsoid a frozen object; the debug
+  argument checks were left out, as in Cesium's release build; only the subset
+  gev uses was kept.

-measured by casting a 32×18 grid of view rays at the ellipsoid; while the scope
-mask is on (the default) only the rays inside its keyhole count, since the mask
-hides or dims the rest. Voice tilt and in-place turns of a free 3D camera above
-1,000 km stop when about a tenth of the frame still shows the surface (or about
-as much as it showed when it started), never less than about 1% of the visible
-frame, and a view that already shows less only keeps or gains what it has. A
-turn that cannot go half a degree further without crossing that limit is refused
-with a reason instead of reported as done, and a turn it accepts turns at least
-that half degree. A voice tilt to an angle (or a bare tilt, to -45°) that the
-limit stops short of is aimed at the angle where it stops, and its result names
-that angle (`pitchDeg`) with a `note`. A turn that keeps or gains surface is not refused, even after
-the window has been resized, except that near the limit, where the planet's edge
-crosses the sample grid, sampling wobble can occasionally refuse one (most often
-above about 15,000 km and on phone or ultrawide frames); nothing then turns away
-from the planet. A turn that starts where the last voice turn left the camera
-keeps that turn's limit, or a higher one if the planet now fills more, so
-repeating the request does not take any more; once anything else has moved or
-turned the camera, a turn is measured from what is on screen. When a camera move
-ends above 1,000 km with no ray on the surface, the camera turns straight down
-at the same position and heading. The end of a move is taken from Cesium's
-move-end event and from a check of its own that samples the pose every 250 ms
-after a move starts and acts once it has held for half a second, because at some
-of these poses the camera drifts by a rounding error every frame and Cesium
-never sees it stop. That check keeps watching until move-end arrives, recovering
-once after each move that comes to rest, and gives up five minutes after the
-camera last moved. Limb glow, and a surface sliver up to about one grid cell
-thick (some 50 px on a 900 px tall frame), can count as out of view. The
-zoom-out guard above keeps wheel and pinch zoom-outs in view; this catches the
-other ways a move can end looking away, such as a saved or shared view that did.
-Views with more surface than that, such as the oblique orbital Director shots,
-are left as they are, and so are tracked or locked cameras, a camera flight in
-progress, a Director scene while it plays (holds included), a pointer held
-down on the globe (a drag held still; with several fingers down, until the
-last is released) and the 2D and Columbus modes; a check a flight, scene or
-held pointer defers runs once it ends. A release outside the window that the
-page never sees counts as given once the window loses focus, the page is
-hidden, the canvas loses the pointer's capture, or the pointer moves with no
-button down. A Director
-shot loaded or replayed outside a run is not a playing scene. A view that loses
-its surface without a camera move (a resize, or turning the scope on) is left as
-it is until the next move. A voice turn requested while the camera is tracked is
-judged by the pose voice's release of the follow camera will leave, before that
-release, so a refused turn keeps the tracking.

-## Wildlife Sightings — iNaturalist and Acartia
+## Navara globe engine — November 5, 2026
 
-**Wildlife Sightings** (`wildlife-sightings`, share-link token `9`) is off by
-default in the Wildlife group between Events and Weather. CONFIRMED and six
-taxa presets round-trip in share links. Voice is off for this layer for now;
-it is outside analyst queries and DETECT. Community observations are not a
-census; private records are excluded.
+Navara, an experimental three.js/WASM globe (`@navaramap/three` 0.2.1), runs
+next to Cesium. It is picked under Display → Globe Engine or with
+`?engine=navara`; Cesium stays the default. Switching is live: the page keeps
+one application, and only the globe-bound parts move to the next engine.
 
-`/api/inaturalist/observations` requests verifiable wildlife in view within
-48 h (whales 7 d). Recency uses observation time: the `d1` date filter and a
-strict rolling cutoff. Date-only rows qualify only when their day starts
-within the window. Close views use a cached random sample of at most 200 rows;
-global samples use newest observations first. Observation caches last five
-minutes (global ten minutes), with stale fallback for at most one hour.
+- **Two Navara choices** (`src/app/engineChoice.js`). **Navara** draws at CSS
+  pixels without MSAA, as Cesium does; SMAA still smooths edges. **Navara HD**
+  (`?engine=navara-hd`) draws at the device pixel ratio with MSAA 4. Both are
+  the `navara` engine to the layers; a pick between them builds the other
+  variant cold and releases the first, so only one Navara holds memory.
+  Measured in headless Chrome (Dubai, 1280×800): Navara 1.6 GiB at DPR 1 and
+  1.8 GiB at DPR 2, Navara HD 1.8 and 2.7 GiB, Cesium 0.93 and 1.08 GiB
+  (Navara used 1.95 and 3.0 GiB before).
+- **Memory.** The canvas context has no antialias (Navara draws into its own
+  targets and copies the result), the cloud shadow maps use the low preset's
+  256² and 2 cascades, and the tile cache budget is the screen-sized targets
+  plus 768 MiB instead of Navara's default of up to 2 GiB, which a long session
+  filled. A released Navara keeps no JS: catalog closures capture the
+  operations, not the scene; a released globe aborts with a reason made at
+  module load (a fresh one keeps the stack, and with it the scene); and
+  `Pass.fullscreenGeometry` from postprocessing is disposed after the view,
+  which otherwise pins the canvas through a three listener.
 
-Observations and grid tiles share a paced priority queue: a four-call burst,
-then one request per second, at most four in flight, ≤60/minute and a persisted
-8,000/day budget. Superseded consumers leave before dispatch. The recovered
-queue tail isolates failures; ordinary grid failures do not fail observations.
-Provider 429 cooldown is shared; 5xx cooldown is resource-specific. Failed tiles
-retain good cells for at most one hour. Stale replies carry `X-Data-Stale` and
-known `Retry-After`. Failures keep filters and drawn rows, reporting DEGRADED
-with retry timing; logs exclude request URLs and upstream exception text.
-A partial failure still draws what arrived: a failed iNaturalist request, or
-one failed half of an antimeridian view, keeps a good Acartia reply and the
-other half, retains that area's last iNaturalist rows and reports DEGRADED.
-The update fails outright only when every requested source failed. Each failed
-source keeps its HTTP status and `Retry-After` (the HTTP status counts when no
-`X-Upstream-Status` is sent), and the next request waits out the longest 429 or
-5xx cooldown among them. One update requests both sources, so the cooldown
-holds the whole layer; a fully successful refresh clears it.
-
-`/api/acartia/sightings` adds Salish Sea marine mammals within 45.5–50.5° N,
-126–121° W, cached ten minutes and stale for at most 24 h. A valid empty
-snapshot, including one whose rows all fall outside coverage or the species
-checks, is a fresh success that clears earlier rows; only a malformed or failed
-upstream reply serves stale and starts a retry cooldown. WHALES accepts only
-recognized cetaceans; other identified marine mammals appear under ALL or
-MAMMALS. Sensitive iNaturalist locations remain 0.2° privacy cells; Acartia
-positions are rounded to 0.01° on the server. Acartia comments are never retained.
-Observer identity is retained only for photo attribution.
-
-`/api/inaturalist/grid` supplies a dedicated, nonpickable billboard density glow,
-with a view-relative density ramp from cool teal to warm amber. Overlapping
-Gaussian splats span four logical cell widths; mono and CRT styles follow map
-and cockpit vision changes. Empty snapshots paint nothing. Full footprints
-stay inside the globe limb with a 5% radius margin; opacity fades from full at
-3,000 km to zero at 8,000 km camera altitude. Culling and cached coordinates
-add no per-frame work and leave sighting counts intact.
-
-Only real sampled observation rows produce taxon badges at their public
-positions. The badges use 28 px screen buckets, a 22 px overlap check and a
-5,000-observation cap. Tinted circles have a white Material Symbols glyph and
-1.5 px dark outline, remaining 12–22 px at all distances, including selection.
-Glyphs: birds `raven`, mammals `pets`, reptiles `egg_alt`, amphibians
-`water_drop`, fishes `set_meal`, insects `bug_report`, arachnids `pest_control`,
-plants `eco`, fungi `umbrella`, other animals `category`, unknown `question_mark`.
-A plain circle displays while the icon font loads. Row counts read
-“{n} sightings in view”, using visible grid totals when available.
-
-Views request at most six tiles, coarsening zoom for complete coverage. Server
-and client keep bounded 400-tile caches for 15 minutes. Cached, stale and
-adjacent-zoom tiles publish before network waits; each arriving tile replaces
-its covered area, including healthy empty tiles. Grid tiles publish even while
-the independent observation request is pending or failed. Enable waits for one
-camera settle; camera acquisition uses moveEnd with a 600 ms debounce. The
-documented UTFGrid endpoint's unspecified cell records have a schema guard;
-see `KNOWN-ISSUES.md`.
-
-Ambient cards use a fixed 96 px image width and a short creator name credit,
-with a bounded frame cache. New cards fill free screen regions; visible cards
-survive a random sample refresh until they leave the view or observation
-window. The 110/125 km show/hide thresholds provide hysteresis; cards scale
-and fade gradually through 120 km. Only painted photos suppress their own
-badge and label. Labels yield to painted cards, then compete by ambient score;
-repeated translated names within 80 screen pixels yield to higher-priority
-content. At most 150 labels enter the host. Titles prefer a word boundary for
-ellipses; accessible names remain complete. Selected thumbnails or names use
-the shared selected chrome and paint lane, with no canvas source link.
-
-Clicking a badge, label or photo flies to its supplied position and opens a
-compact anchored photo card. Selection stays pinned across camera, filter and
-sample changes until explicit deselection or layer disable. Its medium image
-uses `object-fit: contain`, with names, compact observed age and creator/licence.
-The card is the single source link to iNaturalist. Obscured sightings also stay
-text-only; Acartia stays text-only with provider credit and whale guidance,
-and its source link is always `https://acartia.io/`, never a contributed URL.
-Placement avoids actual HUD, toolbar and rail rectangles, panning only when
-necessary while preserving zoom. Escape, close or an outside click closes the
-card and clears selection. Camera/layout changes reposition the card without
-an idle frame listener; shell teardown also removes its host and subscription.
-
-Attribution appears in the layer row and Data attribution popover:
-“iNaturalist contributors · licences per record”, plus Acartia when drawn.
-Disable/destroy releases the glow collection, texture atlas, timers, queues and
-style listeners. Synthetic fixtures cover privacy, acquisition, rendering,
-selection and card placement. Deterministic operation checks run in `npm test`;
-wall-clock budgets run in `npm run test:perf`. All 11 locales are supported.
+- **The engine contract** is `src/globe/contract.js`. `src/globe/cesium/*` and
+  `src/globe/navara/*` implement it, `src/globe/testing/fakeEngine.js` stands
+  in for tests, and `src/globe/testing/contractSuite.mjs` runs the same checks
+  on every engine. `movers` and `lines` are optional capabilities: only
+  Navara has them, and the suite skips their checks elsewhere.
+- **The session owns the state.** Catalog, layer models, sources, selection,
+  camera mode and URL state outlive a switch. A layer that is a session model
+  gets `attachRenderer(engine)` / `detachRenderer()` instead of being rebuilt,
+  so its data is not fetched again. The outgoing globe is parked
+  (`src/standalone/rendererCache.js`), so switching back within three minutes
+  is warm (60-90 ms). After that the parked globe is disposed and its WebGL
+  context lost, which frees about 1.1 GiB for a parked Navara; switching back
+  then builds it cold (1.5-2 s). `?parkedMs=` shortens the delay for QA
+  (`scripts/qa-strict-parked-release.mjs`).
+- **Renderers per engine.** Each layer keeps its model and display policy in
+  engine-neutral files and draws through `render/cesium*.js` or
+  `render/navara*.js`. Cesium renderers are listed in
+  `src/app/layers/renderers.js` (`CESIUM_LAYER_RENDERERS`), Navara ones are
+  loaded by `registerNavaraLayerRenderers` in `src/app/navaraMode.js`. Navara
+  ground effects (heat, pulses, trails, pads, drapes) are declared with
+  `defineGroundEffect` (`src/layers/shared/render/navaraGroundEffect.js`);
+  their insert order is pinned by `navaraGroundOrder.test.mjs`.
+- **Cesium only on demand.** The production build loads `/cesium/Cesium.js`
+  when a Cesium globe starts or a Navara user turns on a feature that still
+  uses Cesium's maths or entity model (traffic, Street Level, the Bhote Koshi
+  event and locator, geo import; `src/app/loadCesium.js`). App code does its maths with `src/geo`, a Cesium-free
+  port of the vector, ellipsoid, transform and time functions that
+  `bitExact.test.mjs` compares with Cesium bit for bit.
+  **Invariant: no module reads Cesium while it loads**
+  (`scripts/check-cesium-load-time.mjs`, run by `npm test`).
+- **Boundaries.** Cesium is imported only from `render/cesium*.js` and
+  `src/globe/cesium/*`; three, postprocessing and Navara only from `navara*`
+  modules, which load through `import()`. `build/initialChunkGuard.js` fails
+  the build when one of them reaches an initial chunk, and
+  `npm run check:main-chunk` holds the main chunk to its gzip budget
+  (`scripts/main-chunk-baseline.json`). Only `src/globe/navara/internals.js`
+  touches Navara's private members.
+- **Navara 0.2.1 workaround.** The SDK keeps feature-change events of deleted
+  vector layers in its queue, so the view never reaches idle. They are dropped
+  each frame (`src/globe/navara/featureQueue.js`).
+- **Strict acceptance.** `node scripts/qa-all-layer-switches.mjs <origin> <out>
+  --serve` builds the commit keyless in a clean worktree and runs every layer
+  and switch scenario under a deny-by-default network policy, with free map
+  tiles from a disk cache and a trap that fails any read of Cesium before it
+  has loaded. Every catalog layer must be asserted on both engines. Point
+  `PUPPETEER_EXECUTABLE_PATH` at an installed Chrome if Puppeteer's pinned
+  build is missing. With an OSM base map Navara lights the globe by the real
+  sun, so scenarios over Austin or San Francisco see a dark frame at local
+  night and fail their pixel checks; run them in local daylight.
+- **Navara 0.2.1 workaround.** The SDK never frees pick batch ids, and the
+  mover banks rebuild their instanced meshes on each attach, so every switch
+  leaked one id per instance of capacity (about 260 KiB of WebAssembly memory).
+  A per-view pool hands released ids back out
+  (`src/globe/navara/movers/batchIds.js`); the long soak asserts both JS
+  objects and native memory stay flat.
+- **Navara 0.2.1 workaround.** The first `layer.update({ show: false })` after
+  a vector layer is added is sometimes dropped, so a zone turned off right
+  after a switch stayed drawn. Polygon displays hide by deleting their layers
+  and rebuild them when shown (`src/layers/shared/render/navaraPolygons.js`).

Global Context does not fabricate a selected-entity model preview: the provisional hand-authored aircraft wireframe was removed because it was not geometry extracted from the selected entity's actual asset.
 - Dependency ownership is reversible: disabling Global Context releases only dependencies it enabled, while user-enabled layers remain on. This also removes the Military-layer suppression handoff when Global Context owned Military, allowing an already-enabled civilian Flights layer to resume its normal mixed rendering. If OpenSky is unavailable and has no last-good cache, Flights requests a capped 250 nm adsb.lol point snapshot around the current view anchor and labels that provenance explicitly; it never relabels military-feed rows as civilian data.

That enable includes the first mission-index load: an HTTP error, timeout, network failure or malformed payload before any index has loaded fails the enable, so Context rolls back to the pre-entry layers instead of committing an empty, isolating mode; the camera returns to its pre-entry view unless navigation took it, and a toast says the mission index could not load. A valid empty index still enters, and a refresh failure after an index loaded keeps its records and the mode. Exiting cancels the layer's own camera flights but never one navigation started. A newer same-target ON request takes ownership of the pending entry without releasing its isolation snapshot, including when it arrives while the prior request is awaiting the adoption guard.

 - Enabled Data Layer controls report normalized feed health on the button (`LOADING`, `DEGRADED`, `STALE`, `FALLBACK`, or `UNAVAILABLE`) while the metadata line retains the source and reason. A partial CelesTrak group failure keeps the usable catalog and reports `DEGRADED`; a total outage keeps last-good catalog data visible but reports `UNAVAILABLE`.
 - On activation it focuses the nearest currently observed aircraft across the civilian and military feeds, with military winning an exact distance tie; if none are available, it focuses an observed AIS vessel. The aircraft search is deliberately uncapped and one refresh-tick retry handles initially empty feeds. This is an attention-priority navigation shortcut, not a high-risk, affiliation, or threat classification.
 - A selected aircraft, AIS vessel, or mapped installation gets a 250 km **context window** with nearby cohort counts, nearest examples, source labels, and stale/unavailable reasons. It emits `NEARBY` or `UNKNOWN`; no detection, engagement, affiliation, or sensor-activity conclusion is calculated.
-- Contacts rows and the Cockpit Contact counts name each cohort's provider: the source of the last snapshot, marked `FALLBACK` or `STALE` as its layer row would be. A poll in flight keeps the mark, where the layer row shows `LOADING`. A flight snapshot from the adsb.lol regional fallback reads `adsb.lol · FALLBACK`, not `OpenSky`.
 - The window's edge is drawn on the globe as a 250 km range ring: a 4 px polyline with a 2 px Context-blue core inside a 1 px dark halo on each side, 2.5 km above the ellipsoid (`AWARENESS_RANGE_RING_STYLE` in `src/layers/awareness/policy.js`). The halo keeps it legible over bright desert and snow, dark ocean and forest, and under the FLIR, NVG and CRT styles, where the earlier 1 px ellipse outline disappeared. It is a polyline because WebGL draws ellipse outlines at 1 px whatever width is asked for, drawn as an unpickable primitive rather than an entity so a click or tap on its edge reaches the contact underneath (headless viewers without a primitive collection get a static entity instead); it is rebuilt when the subject moves. Three dim sonar pulses (3 px with a 1 px dark outline, same colours, at most 60% opacity) grow slowly from the subject at constant speed, one every 3 s and each taking 9 s, and arrive at the ring at about a third of that. Behind each pulse a radial gradient in the same blue fades inward over 35% of the radius. One unpickable 250 km disc draws both the pulse lines and the gradient, its shader reading the pulse radii and opacities each frame, so a click or tap near a pulse still reaches the contact underneath; the disc follows the subject by a model-matrix rotation and is rebuilt only after the subject moves 20 km, and not at all while the pulses rest. While the camera is below the disc's 2.5 km height, where it would sweep across the sky, the pulses rest: the disc is hidden and there is no ring flash, no echo and no frame request. Terrain or 3D tiles higher than 2.5 km (the Alps, Andes, Rockies) still cut through the disc and the ring when seen from above, as the ring alone already did; the height check uses the camera's height above the ellipsoid, not above the ground. While pulses run, the ring dims to 40% and flashes to full strength as each pulse reaches it, fading over 1.8 s. As a pulse front crosses a flight, military aircraft or AIS vessel, the detection overlay draws a second bracket around that contact's own bracket, in the pulse blue on the default detection style and in the style's own line colour under NVG, FLIR and CRT, which spreads outward as it fades over 1.4 s (`AWARENESS_RANGE_ECHO`, read through `src/awarenessEcho.js`; no layer's icon is restyled, and mapped installations have no detection bracket). Pulses are born 5 km out, so the subject itself and anything nearer never echo. Pulses run for 9 s (three ring flashes) after a selection or a camera move, fading in and out over 1.2 s, then rest: the ring stays on screen at full strength, the pulses, gradient and echoes are hidden, and nothing asks for frames, so a parked Contacts view is quiet again. Only a camera move within 1.5 s of the user handling the map (pointer, wheel or touch on the Cesium canvas, which covers a drag's inertia, and a drag or touch begun there keeps counting until its last finger or button lifts, even outside the canvas, unless the window loses focus or the page is hidden first; keys typed elsewhere do not count, nor does input while Cesium's camera controls are off, as in the cockpit view, and a gesture still pending when the cockpit or another owner takes the camera is dropped) wakes them; a moving subject and the app's own camera moves (a tracked aircraft, the cockpit view, an orbit, a fly-to) do not, since they move on every refresh. While they run they never hold continuous rendering: each drawn frame arms one render request 80 ms later (the Cyber sonar cadence, `CYBER_SONAR_RENDER_INTERVAL_MS`), so they repaint at about 12.5 fps and never beat the detection lane's 80 ms gate. Under `prefers-reduced-motion`, or in a scene without primitives or preRender and postRender hooks, there are no pulses or echoes and the ring stays on screen; changing the preference mid-session rebuilds the ring. The ring follows a moving subject once it has moved 250 m.
 - For a selected live aircraft or vessel, the context window refreshes from the existing tracker/feed position every 750 ms, so nearest distances and cohort counts follow the subject without introducing a duplicate poll loop.
 - Aircraft cohort membership uses every locally loaded, selectable contact inside the 250 km window, including a plane hidden only by horizon culling or because its 3D model owns the visual. Counts and navigation therefore do not change with the current camera angle or billboard/model handoff.

The display latency is an intentional product decision — do not "fix" it away. The fleet dead-reckons at ~12Hz (1m² write gating); a contact already hidden behind the horizon whose last position still is re-reckons on a staggered one-in-13-ticks rotation (about once a second) instead, so the worldwide feed's ~13k contacts no longer cost a full pass when well under 1% are on screen. Anything that position puts in view, and any contact with a fleet model, takes the full pass immediately, and hidden-inclusive proximity queries read positions at most about a second old; aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum. A nominally successful worldwide OpenSky response whose own snapshot epoch is more than two minutes old prefers the existing 250-nm viewport-scoped adsb.lol fallback and labels the source/coverage accordingly when that upstream is available. If the fallback is also unavailable, the layer's freshness/error fields use the source epoch—never the cache receipt time—so the UI reports an old snapshot rather than “just now.”

 - **World-space headings at every angle** (`src/data/iconOrientation.js`): aircraft/vessel icon rotation uses the camera right/up basis per tick (alignedAxis always ZERO), which is exact at screen center and for orthographic/nadir views and remains stable through >180° tracked orbits. Perspective rays vary across the viewport, so off-center contacts at oblique pitch can diverge from an exact finite-difference window projection; a regression test pins that known regime, and field evidence decides whether to adopt exact projection with the basis method as fallback. Fleet rotations refresh on camera-pose change; tracked entities per frame. Billboards are horizon-culled via a shared EllipsoidalOccluder.

Left/right describe visible globe motion, while `rotate` turns the camera in place. `tilt` swings the camera about the ground under the crosshair, so the place stays centred and the heading is kept. It tilts in place instead with no ground under the crosshair, from beyond 1,000 km of range, or while an entity is tracked (voice releases the follow camera before moving, so a voice tilt from a tracked view still pivots); pitch stays within -89° to -5°, clamped only in the direction of travel so a top-down (-90°) view can tilt up out of it. Angles and limits are the camera's own pitch; at regional range the pivot's pitch is up to about 8° shallower (the Earth curves away), so the swing solves for the pivot pitch that gives the camera the angle asked for. A pivot swing toward the horizon lowers the camera (height above the pivot is range × sin|pitch|), so the swing stops lowering it at 150 m above the pivot (not above the terrain behind the camera) and the rest of the tilt happens in place. Beyond about 17 km of range the swing never hands over to an in-place tilt (that would lift the crosshair onto the sky); it keeps the camera at least 0.5° above the place's own horizon, which from roughly 500 km stops it short of -5° with the place still centred: a tilt to an angle beyond that stops at the angle reached and says so (`pitchDeg` is the angle reached, with a `note`), a continuous tilt stops there, and a further tilt up is refused as at the limit. A zoom during a pivoting tilt scales the range it holds, as for orbit, but a zoom in stops at the range that keeps that 150 m clearance; a zoom that can move no further (that floor, the 80 m floor, or the cap: 1,000 km for a tilt, where pivoting stops, and 5,000 km for an orbit) is reported as not zoomed. A zoom during a tilt to an angle re-judges the place's horizon limit at the new range: when that moves where the tilt ends, the tilt eases from where it is to the new end (holding the camera's pitch through the range change; a camera the zoom leaves past the new range's limit steps down to it with the zoom, since past it the place would drop behind the Earth), and the zoom's result names that angle (`pitchDeg`) with a `note`. Once the tilt continues in place, a zoom moves the camera like any zoom. A tilt with `pitchDeg` (or with neither angle nor direction, which means -45°) eases to that angle; a positive angle means the same angle below the horizon. `pitchDeg` is absolute, not a step: sent with a `direction` it contradicts, the tilt is refused. An angle the camera already holds answers `unchanged` but still takes navigation, so it stops a running motion and releases the follow camera. A tilt left or right is refused. A voice tilt, orbit, pan or rotate sent while a voice `fly_to_location` is still looking up or flying ("fly to London and tilt the camera" or "fly to Paris and orbit it" arrives as two sibling calls) waits for that flight to land, up to 15 s (moving to a later fly-to in the same reply as soon as it begins, whatever the earlier one reports), so it neither cancels the flight nor gets replaced by it; if the flight is cancelled, finds nothing or times out, the user grabs, touches or scrolls the map during it, or another navigation (a location-panel search, share link or file import, which leave the flight flying) takes the camera during it, the motion is not run and says so. A motion that runs after a fly-to of the same reply has already found nothing (Gemini runs one turn's calls one by one, and passes its turn as the reply) is refused the same way rather than moving the old view; a motion in a later reply runs. `stop` and `rotate_globe` do not wait, and a motion sent before its fly-to is not reordered: it runs at once, and the fly-to's result names the motion it stopped (`stoppedMotion`). Orbit still arms (`armed: 'waiting-for-arrival'`) when it starts during any other camera flight, and captures its target once the tween queue has been quiet for 0.8 s.

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

 - **What it shows.** Events ▸ **S2 GhostMaps** draws the current edition of S2 Underground's KMZ intel products from `github.com/s2underground/GhostMaps`. The products are the Common Intelligence Picture and the 30-day kinetic pull (both on by default), the Border Crisis Map, the Iran Common Intelligence Picture, Iran Kinetic Events, Yemen FLOT, and **Latest Drop**: the newest dated incident file outside those series, `0_Archive`, `Basedata` and `Reference Material`. Each product has a chip in the row. The chip choice is kept in `localStorage` (`gev.ghostmaps.products`) and falls back to the defaults when storage is blocked.
 - **Editions.** `src/layers/ghostMaps/catalog.js` (pure) matches whole repository paths per product. The newest edition wins by the date written in the file name, then by `Export_N`/`vN`. Undated names, such as the fixed 30-day file, are identified by blob sha. Files over 50 MiB are left out (the 62 MB census KMZ, for example). A renamed folder drops the product rather than matching elsewhere.
-- **Event age filter.** One **Event age** switch in the S2 GhostMaps row applies to every selected product: 1, 3, 7 (default), 14 or 30 days, or **All** (every marker). The choice is saved separately from product selection in `localStorage` (`gev.ghostmaps.ageDays`); missing, invalid or blocked storage falls back to seven days. Age comes only from the placemark's `Date of Event` (or `EventDate`/`Date`), never from report, prose or KMZ edition dates. Undated, unparseable and future dates stay visible. ArcGIS `M/D/YYYY` dates with optional AM/PM times and ISO dates are read as UTC when no zone is given; a date without a time covers its whole UTC day, so **1d** still shows yesterday's reports. Events age out every minute while the layer is on. Narrowing the window only removes markers; widening restores them from the cached KMZ. An open card stays while its marker is shown.
 - **Updates.** The repository is not ours, so there is no webhook. `server/providers/ghostMaps.js` starts with the first `/api/ghostmaps` request, so an install that never enables the layer never contacts GitHub.

-- **Aircraft cockpit view:** selecting a commercial or military aircraft reveals a `COCKPIT` action (`C`) once that aircraft's own layer is on; Contacts is not required. The action shows in Contacts (`#cockpit-entry`) and under the Intel HUD's bottom-right readout (`#cockpit-entry-readout`, with the HUD on, in its Tactical and Cyber layouts), so entry needs no Contacts panel. Turning off the ridden aircraft's layer ends the view (the layer clears its tracking). When an air feed the surrounding picture uses is off, the Cockpit says so instead of blocking: Live Signals leads with `MILITARY FEED OFF · PARTIAL PICTURE` or `FLIGHTS FEED OFF · PARTIAL PICTURE`, and the Contact card shows that line in place of its inputs status, so a partial picture is never presented as complete. `control_cockpit` refuses entry with `entryBlockedReason` `contacts-starting` (a Context change in flight), `subject-layer-off` (the aircraft's layer, or with none tracked any aircraft layer, is off) or `no-tracked-aircraft`. Cockpit mode temporarily releases Cesium's orbit-follow transform and drives a first-person camera from the tracked aircraft's existing smoothed display position and course. Its concave helmet-visor HUD shows callsign, UTC time, coordinates, curved roll/pitch guides, and a seven-division heading tape. Ambient commercial and military AIR contacts use a Cockpit near/far band selected by the shared Display 3D mode: Proximity admits at 150 km and retains to 185 km; All admits at 400 km and retains to 450 km. The shared 3D toggle now applies in Cockpit: Off keeps in-range contacts as rotating 2D aircraft silhouettes, while On lets a ready admitted glTF take over without a drawing gap. The Cockpit model cap remains 60 and can only lower the map budget; in-range contacts that are capped or still loading remain 2D silhouettes instead of degrading to out-of-range dots. Contacts outside the selected band use small rotation-free cyan-white pips for civilian aircraft and amber pips for military. The pilot's own airframe is not drawn in first person, and exiting clears the Cockpit band and restores normal map silhouettes/models. The normal left accordion remains available for Layers and Authoring and keeps the same 26vh HUD-aligned anchor used in map mode, independent of whether the bottom-left Contact card is expanded or collapsed; the right-rail CCTV and Context chooser are hidden to avoid duplicating or overlapping the cockpit presentation. When the intelligence HUD is enabled, its classification, scene summary, collection/orbit metadata, coordinates, and imaging-status text remain visible as reduced peripheral cockpit telemetry; the optical center and flight instruments stay clear, and turning the HUD off still hides it. Ground speed, exact heading, and rendered altitude form one compact lower-center instrument cluster, keeping the horizon and peripheral view open. A second live altitude tape hugs the inside-right visor rim: its rail and nine moving ticks are derived from the same responsive keyhole radius, remain 20 px inside the circular edge even on wide displays, fade deeply at both vertical ends, and move continuously behind a fixed current-altitude pointer; its interval tightens automatically near the surface and it is suppressed on narrow screens. Cockpit mode also has a weather-backed transparent volumetric-cloud pass derived from the supplied FBM/domain-warped R&D shader. It renders at no more than 520×320, uses 24 ray steps/three FBM octaves at 12 FPS, is clipped to the visor, fails clear when Open-Meteo is unavailable, and stops its animation completely on cockpit exit. It does not restore the prior CPU weather canvases, precipitation, scene fog, or any map-mode effect. When Contacts is active for the tracked aircraft, the compact `CONTACT` rail adds the 250 km subject window, four cohort counts, nearest observed/mapped example with relative bearing and distance, freshness, explicit uncertainty, and Previous and Next controls plus its own collapse control.

They collapse independently to slim tabs without stopping live data updates. Narrow screens use separated top/bottom fallbacks. Empty-space globe clicks are inert while cockpit owns the camera; `C`, `Escape`, or `EXIT COCKPIT` explicitly exits and restores the same tracked entity and standard follow camera. Unknown feeds remain unknown, selection loss still exits safely without inventing a replacement track, and the cockpit never presents the summary as threat scoring or an all-clear. This is a desktop first-person presentation, not a WebXR session.
 - **Cockpit left-panel clearance:** the Cockpit Contact card and peripheral HUD participate in the adaptive left accordion's live obstacle measurements, including live viewport-height changes. Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
