 - **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`.
+- **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 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.

 - **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.
 - **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.
 - **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.

+Next to the mic, **CHAT** opens a typed chat with silent replies. It uses the selected provider and the same map actions, and never asks for the microphone. OpenAI chat needs an API key (`OPENAI_CHAT_MODEL`), so it is off while `GEV_PREFER_CODEX_OAUTH` pins OpenAI to ChatGPT OAuth; Gemini chat uses a separate text model (`GEMINI_CHAT_MODEL`). Chat and voice panels share the left panels' glass surface and sit above the dock or dock to the right.
 
 > 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.

+- **Typed chat spends the provider keys.** `/api/openai/chat` and `/api/gemini/chat` send the conversation to OpenAI Chat Completions or Gemini `generateContent` with the server's `OPENAI_API_KEY` or `GEMINI_API_KEY`. They require a same-site `Origin` (the Gemini request check), cap request bodies at 512 KB, refuse upstream redirects, cut the upstream call off after 60 s and return only sanitized errors. OpenAI chat can only bill `OPENAI_API_KEY`, so while `GEV_PREFER_CODEX_OAUTH` pins OpenAI to ChatGPT OAuth it refuses with `503` (`CODEX_OAUTH_REQUIRED`) rather than spend the key. After the provider refuses the key or account (a `401`, a `403`, Gemini's `400` `API_KEY_INVALID` or OpenAI's `429` `insufficient_quota`), a route stops sending that key upstream for a minute, or until the key changes.
 - **ChatGPT OAuth voice reuses the local Codex sign-in.** `/api/realtime/oauth-status`, `/api/realtime/oauth-login` and `/api/realtime/token?auth=oauth` answer only loopback connections, behind the same cross-site gate as the token endpoint; the login route also refuses a foreign `Origin`. None of them returns the access token. The login route runs `codex login` (or the executable named by `CODEX_BIN`) with an allowlisted environment that leaves out GEV's provider keys, keeps one attempt pending at a time and cancels it after two minutes or when the server stops. **Limits:** any program on this machine that can reach the server can mint Realtime sessions on the signed-in ChatGPT account, as it can with the API key; a local reverse proxy that hides the client's address defeats the loopback check; and OpenAI has not documented this use of Codex credentials for Realtime, so it may stop working or fall outside the account's terms.

+URLs are built from each camera id under
+`https://www.houstontranstar.org/snapshots/cctv/<id>.jpg`; they are never taken
+from the payload. TranStar's `dir` is the side of the freeway the camera sits
+on, not the way it faces; TranStar's own map reads it as the direction of the
+nearest traffic (South → eastbound, North → westbound, West → southbound,
+East → northbound). That travel direction seeds a low-confidence heading with
+the low-confidence pose, and `None` or an unknown value uses the shared id-hash
+fallback; both stay marked as estimated.

 - 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.
-- 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. The ring follows a moving subject once it has moved 250 m.
+- 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.
 - Nearby examples in the context panel are focus controls: they use their owning layer's existing selection/tracking path, then frame that contact. Static-installation distances use ellipsoidal surface distance so the count matches the ground-projected context disk.

 - Panel POSITION keys are versioned `v8` (`godsEyeView.v8.panelPos.<id>`); collapsed-state keys remain `v6`. The one-time position reset clears stale DISPLAY placements that could overlap the Context rail.
 - Map Source lives in the bottom Visual Presets tray. The left accordion contains no MAP STACK panel, and the `k` panel token that addressed it is gone from the share registry, so legacy `ui=k...` state takes the ordinary unknown-token skip.
 - A dock popover (Visual Presets, Location) auto-dismisses on mouse-away unless pinned. Focus inside the tray defers that dismissal only when the browser reports `:focus-visible` — keyboard focus and typed-into fields hold the tray open; a mouse-clicked tile does not, because Chromium focuses a `<button>` on press.
-- GEV MIC control is a glass capsule (var(--glass-bg), blur(24px) saturate(1.4), 999px radius; panel radius in error state).
+- The voice and chat panels share the left panels' glass surface (`--glass-bg`, `--glass-border`, blur(24px) saturate(1.4); `src/ui/styles/ai-chat.css`). The docked voice control draws its own blur on a layer behind it, so the panels inside it still blur the map. Cyber keeps its own surfaces.
 - The desktop right rail (`#right-context-rail`) owns `DISPLAY`, `CCTV`, its active parameter controls, and `GLOBAL CONTEXT` as one fixed responsive stack in that order. Its compact buttons use the same 176 px width as the left accordion and one consistent 50 px height, share the left stack's 52 px edge inset and measured top baseline across HUD variants, then constrain themselves against visible HUD/chrome rectangles and the remaining vertical corridor. `DISPLAY` is no longer draggable and legacy saved coordinates are ignored.
 - The right rail is labeled **DISPLAY** (formerly "MOVE") and groups, in order, HUD, DETECT, Bloom, Sharpen, 3D, Clean-UI (HUD + DETECT promoted to the top). Its expanded controls retain the same compact 176 px width as the right-side tabs instead of growing to the wider Context detail-card width. It starts expanded on first run and respects the user's later `v6` collapse choice. Collapses/expands with directional chevrons (`◀` collapsed, `▶` expanded).
 - Display and Context use matching 330 px expanded widths and matching compact tab dimensions. The parameter panel is part of Display's expanded content. One right-rail panel is open at a time in every HUD layout and collapsed launchers are hidden; the panel rail beside the stack switches between them (see Panel rails). The most recently opened right-rail panel owns the lane even when it appears later in DOM order; passive restoration and automatic disclosure do not replace that explicit owner. When the open panel exceeds the measured corridor, it scrolls internally.
