fix(import): address review on metadata, bounds, navigation, clock and GPX
- Imported metadata stays inert: descriptions, native labels, properties and KML extended data are dropped from every entity; names are kept as short plain text. GeoJSON loads with a describe that builds no HTML, and simplestyle (including marker-symbol) is dropped, so no icon asset is fetched for a file and GeoJSON draws in its row's color. - Bound geometry before loading: features and vertices are counted in the parsed GeoJSON, the KML document and while reading GPX, and a file over 20,000 features or 250,000 vertices is refused before Cesium builds it. - Imports run one batch at a time, so concurrent picks or drops cannot pass the 12-file cap. - Fly-to framing walks long tracks by index instead of spreading them into a call. - Fly-to is an immediate navigation through the application shell; the fly after an import is a deferred navigation stamped when the batch starts and re-asserted just before flying. - Dated imports never change the shared clock: imported sources expose no clock, entities are available for all time, and a KML gx:Track is drawn as its line. - GPX is read into GeoJSON with one line per track segment, without times. - KML/KMZ rows show a hatched swatch (they keep their own styles); keyboard focus is kept on the same control after hide/show and moves to the next row after remove. - Unit regressions for each, and the rendered QA now imports hostile metadata, dated KML/GPX and a two-segment track, and fails on any request for a file's contents or icon assets, a clock change, or surviving metadata.

### Import Your Own Files (October 2026)
|
||||
|
||||
- DISPLAY ▸ **Import** puts GeoJSON (`.geojson`/`.json`), KML, KMZ and GPX files on the globe. Files come in through the Import button (a hidden `<input type=file multiple>`) or by dropping them onto the globe; the format is taken from the extension, then from the first bytes. Each file becomes its own Cesium data source (`GeoJsonDataSource`, `KmlDataSource`, `GpxDataSource`), clamped to the ground, in its own color from the whiteboard palette, with a row to show/hide it, fly to it, or remove it. The first file of a batch that loads is flown to. Fly-to frames the features' longitudes and latitudes at the surface and lets the camera ground guard lift the eye once the terrain has loaded (`src/ui/flyToDataSource.js`). `viewer.flyTo` is not used here: before the destination's terrain streams in, it frames ground-clamped points kilometers below the surface. Imported files last for the page session: a reload starts empty, and nothing is uploaded or stored.
|
||||
- Runtime entry: `createApplicationTools` (`src/app/tools.js`) calls `initGeoFileImport({ viewer })` (`src/ui/geoFileImport.js`) after the draw tool and defers its `destroy()`, which removes every imported data source, revokes every blob URL, and gives back the drop listeners on the viewer container and the `window.__gevGeoImport` handle (`importFiles`, `list`, `setVisible`, `flyTo`, `remove`, `diagnostics`). Parsing lives in `src/data/geoFileImport.js`.
|
||||
- **An imported file cannot make the page fetch anything.** Before `KmlDataSource` reads a KML/KMZ document, `sanitizeKmlDocument` removes `NetworkLink`, `NetworkLinkControl`, `ScreenOverlay`, `PhotoOverlay`, `Model` and `Tour`, every `href` that is not an image packed in the same KMZ or a `data:image/` URL (an icon then falls back to Cesium's default pin, and a `GroundOverlay` left without an image is dropped), every `styleUrl` that is not a local `#id`, and placemark `description`/`BalloonStyle`/`Snippet` HTML. KMZ images are served from blob URLs. The hint says when something was left out. `scripts/qa-geo-import.mjs` imports files that name a trap host in each of those places and fails on any request to it.
|
||||
- DISPLAY ▸ **Import** puts GeoJSON (`.geojson`/`.json`), KML, KMZ and GPX files on the globe. Files come in through the Import button (a hidden `<input type=file multiple>`) or by dropping them onto the globe; the format is taken from the extension, then from the first bytes. Each file becomes its own Cesium data source, clamped to the ground, with a row to show/hide it, fly to it, or remove it. GeoJSON and GPX are drawn in the row's color from the whiteboard palette (simplestyle properties in GeoJSON are dropped); KML and KMZ keep the styles written in them, and their row shows a hatched swatch instead of a color. GPX is read by `gpxToGeoJson` and loaded as GeoJSON: waypoints are points, each route a line, and each track one `MultiLineString` with a line per `<trkseg>`, so a pause in a recording stays a gap. Imported files last for the page session: a reload starts empty, and nothing is uploaded or stored.
|
||||
- **Navigation.** The row's Fly-to is an immediate navigation through the application shell (`runImmediateNavigation('file', …)`): Cockpit refuses it, and the current follow/track owner is released first. The fly after an import is a deferred navigation: `beginDeferredLocationNavigation()` stamps it when the batch starts and `reassertDeferredLocationNavigation()` re-checks it just before flying, so a camera gesture, search, Cockpit or any newer navigation while files load wins and the import does not fly. Fly-to frames the features' longitudes and latitudes at the surface (thinned to 5,000 points by index, never spread into a call) and lets the camera ground guard lift the eye once the terrain has loaded (`src/ui/flyToDataSource.js`); `viewer.flyTo` is not used, because before terrain streams in it frames ground-clamped points kilometers below the surface.
|
||||
- **Clock.** An import never changes the app's shared clock. The viewer adopts the clock of every data source added to it, so each imported data source reports no clock (`detachImportedTime`); every entity is available for all time, and a time-dynamic KML position (`gx:Track`) is drawn as the line it travels. GPX times are not read at all.
|
||||
- Runtime entry: `createApplicationTools` (`src/app/tools.js`) calls `initGeoFileImport({ viewer, navigation: styleManager })` (`src/ui/geoFileImport.js`) after the draw tool and defers its `destroy()`, which removes every imported data source, revokes every blob URL, and gives back the drop listeners on the viewer container and the `window.__gevGeoImport` handle (`importFiles`, `list`, `setVisible`, `flyTo`, `remove`, `diagnostics`). Parsing lives in `src/data/geoFileImport.js`.
|
||||
- **An imported file cannot make the page fetch anything.** Before `KmlDataSource` reads a KML/KMZ document, `sanitizeKmlDocument` removes `NetworkLink`, `NetworkLinkControl`, `ScreenOverlay`, `PhotoOverlay`, `Model` and `Tour`, every `href` that is not an image packed in the same KMZ or a `data:image/` URL (an icon then falls back to Cesium's default pin, drawn locally, and a `GroundOverlay` left without an image is dropped), every `styleUrl` that is not a local `#id`, and placemark `description`/`BalloonStyle`/`Snippet` HTML. GeoJSON `marker-symbol` (a maki icon asset) is dropped. KMZ images are served from blob URLs. The hint says when something was left out. `scripts/qa-geo-import.mjs` imports files that name a trap host in each of those places and fails on any request that leaves the app's own origin.
|
||||
- **Imported metadata stays inert.** After loading, `scrubImportedEntities` removes every entity's description, native label, properties and KML extended data, and keeps the name only as plain text without control characters, at most 120 characters. GeoJSON is loaded with a `describe` that builds no HTML. The file name is shown with `textContent` only.
|
||||
- **KMZ** is read by a small zip reader (`readZipEntries`: stored and deflated entries through the platform `DecompressionStream`; no encryption, no ZIP64). The main document is `doc.kml`, else the shallowest `.kml`; relative hrefs resolve only to entries inside the archive.
|
||||
- **Bounds.** A file may be at most 50 MB (`MAX_IMPORT_BYTES`), a KMZ may inflate to at most 120 MB in total (`MAX_KMZ_INFLATED_BYTES`, the zip-bomb stop), one file may create at most 20,000 entities (`MAX_IMPORT_ENTITIES`), and at most 12 files are on the globe at once (`MAX_IMPORTED_FILES`; files over that are not read). A refused file names its reason in the hint and does not stop the rest of the batch; a file with nothing to draw is refused.
|
||||
- File names are rendered with `textContent` only.
|
||||
- Gate: `node scripts/qa-geo-import.mjs` (dev server up). Unit: `src/data/geoFileImport.test.mjs`, `src/ui/geoFileImport.test.mjs`.
|

- **Bounds.** A file may be at most 50 MB (`MAX_IMPORT_BYTES`), a KMZ may inflate to at most 120 MB in total (`MAX_KMZ_INFLATED_BYTES`, the zip-bomb stop), one file may hold at most 20,000 features (`MAX_IMPORT_ENTITIES`) and 250,000 vertices (`MAX_IMPORT_POSITIONS`), counted before Cesium builds anything (`countGeoJsonGeometry`, `countKmlGeometry`, and while reading GPX), and the entity count is checked again after loading. At most 12 files are on the globe at once (`MAX_IMPORTED_FILES`): imports run one batch at a time, so two picks or drops in quick succession cannot pass the cap; files over it are not read. A refused file names its reason in the hint and does not stop the rest of the batch; a file with nothing to draw is refused.
|
||||
- **Keyboard.** Hide, show and remove rebuild the list without losing focus: the same control on the same row keeps it, a removed row hands it to the next row (else the Import button).
