Merge upstream/main: cockpit emergency, GNSS integrity and GeoJSON import meet i18n

Browse Source 
Upstream advanced past the KartaView merge: transponder-emergency HUD
wording (formatCockpitEmergency in cockpitMath), the GNSS integrity
layer joined the Events group, and a GeoJSON/KML/KMZ/GPX file-import
control landed - all in regions this branch localizes.

- cockpitMath: upstream's formatCockpitEmergency kept alongside the
  branch's formatter-injected Context scope (module stays i18n-free;
  squawk/ADS-B codes and the broadcast label are data).
- cockpitInstruments: the emergency HUD line composed with t()
  placeholders; fleet/feedState stay translated, the 'emergency' class
  toggle kept.
- layerPanel: upstream's gnss-integrity id with msg('Events').
- package-boundaries: both sides' entries unioned.
- New upstream UI strings marked and translated, as the branch's
  unmarked-string detector requires: the geo-import control's markup
  (data-i18n-title/-aria-label/text), its list titles, hints and
  summarize() lines (t/tn with placeholders), the aircraft emergency
  labels (msg data), and the GNSS legend blurb (t with placeholders).
- es/ru catalogs: 26 new keys each (2019 messages).

npm run i18n: complete, no unmarked strings. npm test: 6739/6741 (the
one failure is the pre-existing environmental OPENAI_API_KEY leak in
devFreshDotenv). Build passes.

- Flights and Military Flights highlight emergency transponder broadcasts in
fleet billboards, 3D models and Cockpit contacts. Colors update when a status
starts or clears. Emergency squawks outrank ADS-B priority statuses; GEV
reports minimum fuel and lifeguard without red tint. Cockpit names the code
or ADS-B status, and analyst/voice results retain broadcast provenance and
the latest known contact time. One omitted ADS-B status poll during a source
switch may retain the previous status if the squawk is unchanged; an explicit
clear takes effect immediately. Broadcasts are not confirmed incidents.

leave the shared clock alone, and report malformed or oversized files.

screenshots. Thanks to [Chase Mills](https://github.com/kapturner) (#925).
- GNSS Integrity (Events, voice-addressable, share token `3`) draws navigation
accuracy scores from a keyless regional adsb.lol sample; aircraft-level analyst
queries are unavailable for these aggregate cells. Cells do not intercept
map clicks. Pan/zoom refreshes automatically; feed failures retain the display
and explain the next retry. Aircraft-reported quality includes MLAT-positioned
contacts after GPS loss, excludes TIS-B/MLAT-derived quality, and locates GPS-loss
evidence at the last good GNSS position when available. Scores discount one
bad aircraft per cell and retain 30 minutes of visited-view evidence; they
do not confirm jamming. See [method and limits](DATA_SOURCES.md#gnss-integrity).

- Live HLS cameras play on a page opened over plain HTTP from another machine
(`HOST=0.0.0.0`). The client lease id came from `crypto.randomUUID`, which
browsers only expose in secure contexts, so starting a live feed threw
before playback. The id now falls back to a v4 UUID built from
`crypto.getRandomValues`, which the server's lease check accepts.
- Move Google geocoding behind the local server. Forward and reverse lookups now
go through `/api/google/geocode` and `/api/google/reverse-geocode` with the
server key, joining Places and Street View. Google's Geocoding web service
refuses referrer-restricted keys, so the previous browser call left
`SECURITY.md`'s advice and working search mutually exclusive: the bundled
browser key had to be unrestricted for search to work at all. That key now
needs only the Map Tiles API and the Maps JavaScript API (Street View). Keyless sessions and the Photon/Nominatim
fallback order are unchanged.

Google Maps Content (tiles, geocodes, places) **may not be cached, stored, rehosted, or committed** — this app only ever uses it live, which is the compliant pattern. The "Google" attribution is displayed on the globe and must stay visible. Restrict your key (see [SECURITY.md](SECURITY.md)).
- **OpenSky Network.** Its license is **non-commercial**, and operational use of the REST API in a live product can require a prior written agreement with OpenSky — even for non-profit/government use. If you deploy this commercially, contact OpenSky for your own terms. The flights layer is a toggle and runs anonymously by default.
- **adsb.lol flight fallback.** When OpenSky is unavailable and no last-good OpenSky response exists, the server requests a cached, capped 250 nm adsb.lol point snapshot around the current camera subpoint. This is regional observed context, not worldwide completeness; provenance is exposed in the Flights stats/context row. Military ICAOs remain reconciled through the existing dedicated military registry rather than duplicated.
<a id="gnss-integrity"></a>
- **GNSS integrity (adsb.lol).** A separate keyless point request samples a 250 nm
circle around the screen centre, snapped once to whole degrees. This does not
reuse the Flights fallback cache. Cache lifetime is 60 s; 429 backoff is capped
at one hour and other upstream failures cool down for 15 s. Future access may
require feeder keys under the [API terms](https://github.com/adsblol/api).
Airborne decoded ADS-B v1/v2 aircraft with a known 0–60 s position age qualify,
including MLAT-positioned aircraft still broadcasting their own quality.
TIS-B/MLAT-derived NIC and NACp are ignored. GPS-loss evidence uses
`gpsOkLat/gpsOkLon` when present, otherwise the current known position.
The proxy strips identity metadata and tags its response with classifier
`gev-nic-nacp-v2`; rows carry only integrity facts.
The method has three separately attributed parts:
1. **GEV classifier (unvalidated):** GPS-loss flag, aircraft-reported NACp < 8,
or aircraft-reported NIC < 7 except NIC 0 with NACp ≥ 10 (unknown containment).
The numerical minima come from US 14 CFR 91.227(c), not a published jamming
classifier. Readsb's [JSON contract](https://github.com/wiedehopf/readsb/blob/dev/README-json.md)
describes the quality field origins and GPS-loss flag.
2. **GPSJAM aggregation:** score = `100 × max(0, bad − 1) / total`, with percent
bands < 2, 2–10, > 10. One bad aircraft is discounted. This is not the raw
share of bad aircraft. See the [GPSJAM FAQ](https://gpsjam.org/faq).
3. **GEV window:** 30 minutes over visited views, at least three aircraft per
0.5° cell. These bands were developed for daily totals; with fewer than ten
observations a cell can skip the middle band. Source timestamps date evidence
even through cache replays, and degraded evidence expires independently.
Medium/high cells report navigation-integrity anomalies. Interference is one
possible explanation, not a detected or located emitter. Avionics faults and
manoeuvring military trainers can also lower reported accuracy. Blank areas
can be outside coverage or lack enough observations. Attribution: adsb.lol
contributors, ODbL 1.0; GPSJAM for aggregation only.
- **adsbdb enrichment.** `/api/adsbdb` resolves an ICAO hex to aircraft type, model name and registration, and the tracked flight's callsign to an airline and an origin/destination pair. Fan-out is deliberately small because adsbdb is a free community API that publishes no quota: at most 4 requests in flight, dispatches dripped to roughly 5/s, and each key asked for at most once per session, with route lookups reserved for the tracked aircraft. The dev-server proxy caches each key for 24 hours in `.gev-cache/adsbdb.json`, negative answers included, so fresh entries survive server restarts. That gitignored cache remains local to the deployment and is not bundled with this repo. adsbdb publishes no general service license; its README says the route data may not be copied, published, or incorporated into other databases without the explicit permission of David J Taylor, Edinburgh. Deployers are responsible for obtaining any permission their use requires. Enrichment is best-effort and fail-silent — a flight that gets no answer keeps what the flight feed already gave it.
- **Launch Library 2.** `/api/launches` makes a server-side rolling-30-day query against the supported v2.3 detailed launch endpoint, caches successful responses for 15 minutes in memory and on disk, and serves the last successful response during a throttle or transient outage. Anonymous access is limited to 15 calls/hour; deployments can provide `LL2_API_TOKEN` for authenticated access. The Space Devs' published terms permit using and sharing the API data in any form, ask users not to forward it without adding value, disclaim complete accuracy, and encourage—but do not require—attribution. This app keeps a courtesy credit. Payload and stage/recovery records are shown only when supplied. Failed launches expose their source status and never receive fallback orbit geometry or a live/estimated marker. LL2 supplies launch context and event timing, not continuous ascent telemetry or live orbital state.
- **TfL JamCams.** The camera list comes from the keyless `api.tfl.gov.uk` endpoint (an optional `TFL_APP_KEY` raises its rate limit); frames come from TfL's public S3 bucket. The "Powered by TfL Open Data" attribution is required by TfL's terms and is registered in the Data attribution popover.

### Three deliberately client-side keys — restrict them
These are designed to be used directly in the browser (like a Mapbox public token). They are injected into the client bundle via Vite's `define`, so they **will** be visible in browser devtools. Scope and restrict them rather than trying to hide them:
1. **Google Maps API key** — loads Photorealistic 3D Tiles directly and powers GEV place search and Street View (Maps JavaScript API; add it to the key's API restrictions). **Restrict it** (HTTP referrer + API restriction to the required Google APIs) in the Google Cloud Console. An unrestricted key in a public deployment can be abused and billed to you.
1. **Google Maps API key** — loads Photorealistic 3D Tiles directly and powers Street View (Maps JavaScript API; add it to the key's API restrictions). **Restrict it** (HTTP referrer + API restriction to the required Google APIs) in the Google Cloud Console. An unrestricted key in a public deployment can be abused and billed to you. Restrict it to the **Map Tiles API and Maps JavaScript API only**: a referrer restriction applies to the Maps JavaScript API and the client SDKs, not to the web services, so a key carrying Geocoding under one is refused with `API keys with referer restrictions cannot be used with this API`. Search does not need it — geocoding goes through the server proxies above (#363).
2. **Cesium ion token** (`CESIUM_ION_TOKEN`, optional — for ion-hosted Google Photorealistic 3D Tiles, Bing world imagery, and world terrain) — used as `Cesium.Ion.defaultAccessToken` client-side. Use a public **`assets:read`** token with **URL restrictions** for any hosted deployment. The Community plan has eligibility and usage limits; a public token is not a secret, but it can still consume the account's quota.
3. **Mapillary client token** (`MAPILLARY_CLIENT_TOKEN`, optional, Street Level) — used by the MapillaryJS viewer and Graph API lookups in the browser, and by the server's coverage-tile proxy. Mapillary client tokens are meant for browser use.
> The explicit browser `define` block in `build/vite.js` controls exactly what reaches the client: only these three keys. Everything else stays server-side.
**Places and Street View never needed to be on that list** (#33): they're called from the server-side proxies in the table above, which use `GOOGLE_MAPS_SERVER_API_KEY` when it's set. Splitting it from the browser-exposed key lets each key's Google Cloud restriction actually match what it does — the browser key referrer-restricted to the APIs the client loads, the server key IP-restricted (never a referrer, since it never leaves your server) to Places + Street View Static — instead of one key that has to be either over-permissioned or broken for one of its two jobs. A single shared `GOOGLE_MAPS_API_KEY` still works if you don't split them; it just has to cover every API both sides use.
**Places, Geocoding and the Street View Static fallback never needed to be on that list** (#33, #363): they're called from the server-side proxies in the table above, which use `GOOGLE_MAPS_SERVER_API_KEY` when it's set.

A single shared `GOOGLE_MAPS_API_KEY` still works if you don't split them, but then it cannot carry a referrer restriction at all: the web services refuse one, and search would be the half that breaks.
Never commit real keys. `.env` is gitignored; only `.env.example` (placeholder names) is tracked. On macOS `dev-fresh.sh` can read keys from the Keychain; plain Vite uses env vars or a local `.env`, and Pinokio uses its ignored app `ENVIRONMENT` file.

Regression surface: `src/annotations/drawMode.test.mjs` and `src/data/inputOwnership.test.mjs` (pure), `src/annotations/drawToolBehaviour.test.mjs` (the tool driven against DOM and viewer doubles — leases, borrowed input actions, teardown, the Enter key, preview heights), `src/annotations/drawTool.test.mjs` (structural: where files live, which ids the markup carries, what the docs may claim), and the rendered harness `scripts/qa-draw-tool.mjs`.

### Import Your Own Files (October 2026)
- DISPLAY ▸ **Import** reads GeoJSON (`.geojson`/`.json`), KML, KMZ and GPX from the picker or a file drop anywhere in the app. Each file gets show/hide, Fly-to and Remove controls. GeoJSON and GPX use the row's color; KML/KMZ retain their styles and show a hatched swatch. The file bytes remain on the device for the page session. Rendered overlays can appear in map screenshots sent through voice or other existing screenshot tools.
- **Ground and height.** GeoJSON XYZ coordinates become ground footprints. KML ground lines/rings are tessellated; static recorded tracks preserve their original vertices, segment gaps and explicit altitude modes. KML with absolute/relative altitude keeps that meaning. Ground pins resolve in batches of 256 against loaded terrain and, in the nearby camera footprint on photoreal maps, `clampToHeightMostDetailed`, then draw in one owned native BillboardCollection per file, with static positions and no per-frame point Entity visualizer or clamping callbacks. Point metadata remains in `dataSource.importedEntities` for framing/style inspection; non-point geometry stays in the normal source collection. Pin collections mount only after source admission, follow file show/hide, and are destroyed on removal. Settled camera/map-source changes and completed terrain loads refresh visible files through the same serial queue; distant points retain their latest available height. No detailed worldwide terrain sweep is started. Nearby mesh sampling can add requests/time; configured photoreal providers require separate validation. The depth test is disabled for ground pins, matching Draw's marker visibility policy.
- **Navigation.** Row Fly-to uses `runImmediateNavigation('file', …)`; Cockpit can refuse it and existing follow/track ownership is released first. Automatic Fly-to is stamped when a batch is submitted and reasserted before flying. Pointer/wheel gestures and newer navigation supersede it, including time spent in the queue. Framing uses every finite visible point/path/polygon-hole/wall vertex plus rotated overlay bounds, with viewport-aware range and a nadir view. The target uses available terrain/cached ground height and the ground guard on arrival. Empty footprints never fall back to deferred `viewer.flyTo`.
- **Clock.** Imports expose no source clock and no entity availability. KML times/view metadata are removed before loading; recorded tracks become static lines. GPX segments remain separate and GPX times are ignored. The shared clock stays unchanged.
- **Input handling.** Coordinates and GeoJSON geometry types are checked before Cesium allocation. Only short plain names reach GeoJSON property bags; file IDs, custom CRS and styling properties are removed. KML feature/geometry IDs are removed while Style/StyleMap references remain. Local style references are trimmed, incomplete style pairs removed, hidden-folder flags normalized to the import's show control, and unsupported prototype-named elements removed. UTF-16 BOMs and common KML namespace export defects are handled. Empty drawable content is refused. A loader failure or timeout does not hold the next file indefinitely; teardown aborts pending waits.
- **References and images.** File-authored remote links/icons/styles, network links, models and screen/photo overlays are removed. Packed KMZ and embedded PNG/JPEG/GIF/WebP/BMP images remain local; decoded dimensions are checked before image decoding against a total 16-megapixel and 8,192-pixel-side budget per file. Blocked IconStyle images fall back to local pins; authored empty icons remain empty. Colored overlays without an Icon survive; overlays with a removed external image are dropped. Metadata, native labels and descriptions are removed, and generated pins share one lossless image URL per canvas.
- **Bounds.** File size ≤50 MiB; inflated KMZ ≤120 MiB; ≤20,000 entities (including multipart children and Folder containers); ≤250,000 positions; ≤2,000 normalized style definitions and distinct image links; ≤12 files per session. Exact repeated styles share definitions without changing inheritance or inline overrides. Files of 20–30 MB fit the byte budget, subject to geometry/image limits. Refusals name a reason and batches continue; with multiple failures the hint shows the first reason.
- **Lifecycle and keyboard.** `createApplicationTools` wires `initGeoFileImport` with viewer, navigation, ground services and map-source subscription. Destroy aborts pending work, unsubscribes, removes data sources, revokes blob URLs, removes document/canvas listeners and releases `window.__gevGeoImport`. List rebuilds retain keyboard focus; removing a row hands focus to the next row, else the previous row, else Import.
- **Validation.** `node scripts/qa-geo-import.mjs` covers all four formats and real painted show/hide. Run `node scripts/qa-geo-import-regressions.mjs` against both dev and preview for XYZ/track heights, failure recovery, namespace/BOM support, portrait framing and panel drops. `node scripts/qa-geo-import-large.mjs [--file /absolute/path/sample.kml] [--expect-local-pins]` checks a 27.6 MB repeated-style file, native style/image equivalence, large-file painted output and frame times. It records the WebGL renderer; software-rendered runs do not establish GPU performance. Unit tests live beside the data/controller/framing modules.

- **The TRACKED contact's 2D↔3D handoff is DEFAULT behaviour (2026-08-19), driven by camera distance alone.** It does NOT consult the DISPLAY-rail `3D` toggle, which continues to own the FLEET (the un-instanced draw-call budget stays the operator's decision). Policy lives in `src/data/trackedModelRegime.js` and is shared by both layers: enter below `TRACKED_MODEL_ENTER_ALT_M` = 150,000 m and hand back to the billboard only above `TRACKED_MODEL_EXIT_ALT_M` = 172,500 m. **The swap distance was set by playtesting on 2026-08-20:** a first pass at 1,000,000 m switched too early; 2D reads correctly at ~600 km and the handoff belongs at ~150 km. **Consequence, recorded on purpose:** the tracked contact now enters 3D NEARER than the FLEET does (`MODEL_ALT_CEIL_M` = 800,000 m, unchanged), so with the DISPLAY-rail `3D` toggle on, 150–800 km draws surrounding contacts as models while the selected one is still a glyph. Nothing double-draws (the fleet pass skips the tracked icao) and aligning the two is a fleet-side decision, deliberately out of scope. **The two thresholds are asymmetric on purpose:** a single threshold makes a tracked orbit sitting ON the boundary strobe billboard↔model as the camera's altitude wobbles across it. Do not collapse them. The latch is scoped per selection, so a new target re-evaluates against the ENTER ceiling rather than inheriting the previous target's exit band. Exactly ONE model is involved; it loads on demand when the regime opens, is HIDDEN (not released) on regime exit so re-entry has no load gap, and is released by the existing teardown on deselect/re-track/destroy. Cockpit and TR-3B suppression are unchanged. **Two invariants around it:** (a) the hysteresis latch AND the load-failure latch are per-selection state cleared by `_resetTrackedSelectionState()` in the tracking lifecycle (deselect / re-track / cross-layer / init / destroy) — the predicate's icao-change guard is defence only, since it needs a drawn frame while nothing is selected and the render governor's idle mode does not promise one; (b) on-demand loading is bounded at 3 attempts per selection with a 1.5 s backoff and one console warning naming the asset — the driver runs every `scene.preUpdate`, so an unbounded catch means a missing GLB spins load→reject at frame rate. The billboard stays the visual throughout a failed load.
- **Grounded 3D handoff is terrain-validity gated (2026-08-23).** A ready civilian or military glTF does not own the visual until `groundSnap` (`src/data/groundSnap.js`) can answer with a MEASURED photoreal-surface height. On success the layer writes `height + the model's measured belly offset` before revealing the model. Cache movement is measured on the WGS84 surface, not across altitude, so a stationary contact keeps its snap through poll-time vertical-datum changes. Model existence or GPU readiness alone never suppresses the billboard floor, and ordinary zoom/style/deselect transitions preserve a valid snap cache. **Two states, and the difference is the whole design.** COLD — nothing has ever resolved for this icao (tiles still streaming on first sight, sample failure, backoff after a first miss): there is no evidence of where the ground is, `heightFor` returns null, the model stays hidden and the depth-test-free 2D billboard remains opaque and floored. WARM — a snap resolved and then a >`MOVE_INVALIDATE_M` (50 m) taxi move stopped it answering directly: the measurement is DEMOTED to a bounded last-known rather than deleted, and it keeps answering while the resample is outstanding, so a taxiing aircraft does not pop 3D→2D→3D across a 2–30 s retry backoff. The bound is `HELD_SNAP_MAX_DRIFT_M` = 250 m from the spot the value was measured at, past which the hold is dropped rather than stretched and the contact is COLD again. It is spatial with no timer beside it (ground under a contact that has not moved does not change; what invalidates the value is the contact MOVING) and deliberately a quarter of the billboard chain's `HELD_FLOOR_MAX_DRIFT_KM` — that hold only ever RAISES a sprite, while a held snap IS the model's placement, so its error shows in both directions. A fresh sample releases the hold, and so does a ground flip (which already calls `forget`). **A loading model is HIDDEN, never zero-scaled:** admission sets `show = false` (Cesium's default is `true`, and an unplaced primitive would claim the visual at the identity matrix), and ownership is `ready && show` — Cesium 1.138's `Model.update` has no `show` guard, so hiding a primitive costs its load nothing.
- Commercial and military aircraft use the same high-level FLEET model regime: 2D billboards when zoomed out, optional glTF models when closer, controlled by the DISPLAY rail `3D` toggle and `Proximity` / `All` modes. Since 2026-08-16 (Hangar fleet) models are PER-CLASS: real CC-BY GLBs for light/bizjet/turboprop/widebody/helicopter/uav (`CLASS_MODEL_REAL` in `src/data/aircraftClass.js` — meters-baked, scale 1, per-model belly/radius; provenance in `public/models/README.md`), the shared `airplane.glb` for the remaining civilian classes, and the military layer maps weight classes (real GLBs / 747 heavies / `jet.glb` fastjets, per-model heading offsets, always flat amber). Textured civilians carry a HEAVY tint, not a light one: `MODEL_COLOR_BLEND_AMOUNT` is `0.94` in BOTH layers under Cesium's `ColorBlendMode.MIX`, so the class colour supplies 94% of the surface and the asset's own texture ~6%. The visual direction is clean light silhouettes with only a weak diffuse contribution from the approved textures, so liveries deliberately do NOT read. IR boost raises the blend to a full `1.0`. Under NVG/FLIR (map preset or Cockpit vision) models render unlit flat-white at full alpha and scene fog is disabled (fog otherwise blacks out distant models with the globe hidden); state restores on exit.

- The DISPLAY-rail `3D` toggle is the user-facing activation path for both aircraft layers. Their small approved GLBs build their render resources without Cesium's frame-spread job queue, preventing continuous Photorealistic 3D Tiles streaming from starving model readiness; model caps, tracking, camera, and fallback billboards are unchanged.
- **The `3D` toggle DEFAULTS ON in `proximity` on a first run.** Proximity is itself the budget — models appear only below `MODEL_ALT_CEIL_M` and only for the nearest `MODEL_MAX` in view — so the default costs nothing at globe scale, and `all` remains a deliberate opt-in. A fresh boot runs NO layer-state restoration (`LayerStateCoordinator.start()` returns early with neither a share payload nor stored state), so four independent initializers decide what a first-run operator sees and must agree: `booleanOption('models3d', 'e', true)` in `src/data/layerState.js`, `_models3dEnabled = true` in BOTH flight layers, `this._models3dEnabled = true` in `src/ui.js`, and the `active` / `visible` classes on `#models3d-toggle` / `#models3d-mode-row` in `index.html`. All four are pinned together in `src/data/layerState.test.mjs`. Explicit state still wins: because the codec omits default-valued options, `models3d: false` is now what travels in a link (`lo=…f.e.0`) and restores OFF at both aircraft layers. **Consequence for returning users:** a stored `gev:layer-state:v2` blob is a FULL options snapshot, so a session that wrote one before this change carries `models3d:false` and keeps 3D off until the operator flips it (or clears the key) — the durable snapshot is treated as the recipient's own state, by design.
- **Consequence of the flip on the recorded tracked/fleet inversion:** the 150–800 km band where surrounding contacts draw as models while the SELECTED one is still a glyph is now what an operator sees WITHOUT arming anything. The inversion itself is unchanged and still deliberate (see `src/data/trackedModelRegime.js`); only its reachability changed.

/**
* qa-emergency-squawk.mjs — headless proof for transponder emergency highlighting.
*
* Drives the REAL app in headless Chromium against a dev server (keyless).
* `/api/flights` and `/api/military` are stubbed in the page so the codes
* are deterministic; everything downstream (normalizers, records, rendering,
* Cockpit HUD) is production code.
*
* (i) TINT — a civil 7600 and a military ADS-B `general` emergency are
* drawn red; a normal civil flight stays white, a normal military
* flight stays amber, and a military `minfuel` priority stays amber.
* POLL/MODELS verify existing untracked billboards and 3D models
* repaint when emergency status starts and clears.
* (ii) HUD — tracking the military emergency and entering Cockpit names
* the broadcast code on the aircraft-meta line, in red.
* (iii) CLEAR — the next poll drops the code: the HUD line returns to its
* normal wording (the status is not sticky).
* (iv) RELEASE — the code returns and tracking stops: the restored fleet
* billboard is red, not the plain military amber.
*
* Screenshots saved to qa-shots/emergency-*.png (gitignored).
*
* Run: node scripts/qa-emergency-squawk.mjs --url http://localhost:4173
* Optional: --timeout-ms 180000 for a slow boot.
* Exits non-zero on any FAIL. Does not commit anything.

* Rendered acceptance for DISPLAY ▸ Import: real files through the real file
* input and a real drop, parsed by Cesium in the page.
*
* Proves: GeoJSON, KML, KMZ (with a packed icon and ground overlay) and GPX
* each become one row and one data source; the imported shape actually paints
* on the globe in its row's color (a GeoJSON `stroke`/`fill` does not override
* it) and stops painting when hidden; no import makes the page request
* anything named in it (network link, remote icon, remote style, palette
* icon, balloon or extended-data HTML, maki marker) or anything outside the
* page for it; no entity keeps a description, label or properties; dated KML
* and GPX leave the app's clock alone and still draw now; a GPX track keeps
* its two segments apart; keyboard focus survives hide/show; a dropped file
* imports like a picked one; a file that is not geodata is refused with a
* reason and leaves nothing behind; Remove gives every data source back; no
* page errors.
*
* Usage: dev server up (`npm run dev`), then `node scripts/qa-geo-import.mjs`.
* QA_BASE_URL (default http://localhost:4173), QA_SHOT_DIR, QA_HEADFUL=1.

/**
* qa-gnss.mjs — headless proof for the GNSS Integrity layer
* (id `gnss-integrity`): low navigation accuracy reported by ADS-B.
*
* Drives the REAL app in headless Chromium against a dev server (keyless).
* The live section reads adsb.lol through `/api/gnss-integrity` (60 s server
* cache, one upstream read per whole-degree anchor); the other sections
* stub that route in the page so they are deterministic.
*
* (i) LIVE — over Poland and the southern Baltic the layer settles with no error,
* one geometry per cell and legend band counts that sum to the cell
* count; cells are required only when the returned rows, binned
* with the layer's own rules, reach the per-cell minimum (live
* traffic varies by hour). Requires a non-stale response no older than 60 s.
* (ii) BANDS (synthetic) — a 10-aircraft cell with 5 degraded is high,
* a 30-aircraft cell with 2 degraded is medium, a 3-aircraft cell
* with 1 degraded is low (first bad discounted), a clean cell at sea
* is low, a 2-aircraft cell is withheld; `stale: true` reaches
* getStats. Every band is drawn and low is shown over land and sea.
* The row reads as low navigation accuracy, and stats carry the
* machine-readable provenance (GEV classifier, gpsjam bands, window).
* PICK verifies actual perimeter and empty-ground clicks under GNSS.
* CAMERA/GLOBE verify automatic sampling and the screen-centre anchor.
* (iii) FAILURE — the route stubbed to 502: stats.error is set and the
* cells already on the globe are kept.
* (iv) DISABLE — owned ground primitives are hidden.
* (v) KEYBOARD — the row's toggle button, focused, turns the layer on
* with Enter and off with Space, keeps focus and names its state.
* (vi) VIEWPORT — at a 390x844 phone viewport the open row and its legend
* fit the panel width with no horizontal overflow.
* (vii) AGE (synthetic) — a fresh page whose stubbed proxy replays the same
* stale snapshot observed 31 minutes ago draws nothing and reports no
* error; observed 29 minutes ago it draws its cells. The replay keeps
* its observation time instead of restarting the 30-minute window.
*
* Screenshots wait until every cell's ground geometry is built and show the
* open Data Layers row with its legend. Visual proof saved to
* qa-shots/gnss-*.png (gitignored).
*
* Run: node scripts/qa-gnss.mjs --url http://localhost:4173
* (also against a built preview: npm run build && npm run preview,
* then pass the preview URL)
* Optional: --timeout-ms 180000 for a slow boot.
* Exits non-zero on any FAIL. Does not commit anything.

* Aircraft broadcasting DO-260 version 1/2 ADS-B report how much they trust
* their own position: NIC (integrity containment radius) and NACp (position
* accuracy). A cluster of aircraft reporting low values in one area is a
* navigation-integrity anomaly. Jamming or spoofing is one common cause, so
* such clusters are a well-known public proxy for GNSS interference, but
* avionics faults and old transponders also report low values: suspected
* interference is a second, unvalidated interpretation, never the primary

*
* Three separately sourced parts make up the method (see `gnssProvenance`):
* - Per-aircraft classifier, defined by GEV: aircraft-reported NIC < 7
* (except unknown NIC 0 with NACp >= 10) or NACp < 8 (borrowed
* from the US 14 CFR 91.227(c) ADS-B Out performance minima, which are not
* a published interference classifier) or the readsb/tar1090 `gpsOkBefore`
* flag. gpsjam.org does not publish its per-aircraft threshold.
* - Cell aggregation: gpsjam.org's published formula and 2% / 10% bands.
