Cesium treats the first imagery layer shown on the globe as its base
layer and stretches that layer's edge texels over the whole globe. With
no base map under it, a KMZ ground overlay turned the whole globe its
edge colour. The Cesium imagery adapter now keeps a floor under an
engine layer that covers less than the globe (a bounded rectangle, or
Web Mercator tiles, which stop at ±85.05°) whenever that layer would
otherwise be the base layer. The floor is one transparent pixel over the
globe at alpha 0, so Cesium draws nothing of it. It is placed when the
adapter adds or changes a layer, and again at each scene preUpdate,
before Cesium picks the base layer. When base imagery lies under the
layer, which is the app's normal state, there is no floor. A bounded
layer now draws only inside its rectangle, as the contract says.
When the globe is not the drawn surface, the import display now clamps
ground pins to the drawn scene, as Cesium's import did whenever the
globe was hidden. Before, it did this only for the map's own 3D tiles.
Each height query now leaves out the point sets of every imported file
on the engine, not only the file's own sets: Cesium's import kept all
imported pins out of height queries, so a higher pin from another file
never became the ground. The display also gives a footprint with its
points at the heights they are drawn at, and flying to a file frames
pins on raised tiles as Cesium did. Cesium's import clamped visible pins
with clampToHeightMostDetailed, which loads the finest tiles. The
display samples the tiles drawn now and samples them again after the
camera stops and while tiles load.
The KML reader's parity test against KmlDataSource now includes the
large-file QA's style case: a shared style with point, line and polygon
parts, inline overrides of each part, and named styles and an inline
StyleMap pair that are alike. The reader matches Cesium there.
QA scripts:
- qa-geo-import moves the camera over the files before it reads which
pins show. Ground pins are hidden only beyond the horizon.
- qa-geo-import-large compares clamped pins by longitude and latitude.
Cesium keeps a clamped billboard at its file height, while the import
draws its pins on the sampled ground.
- qa-geo-import-regressions gives its 3D-tiles fixture a non-zero
tileset geometricError, because Cesium never draws a tileset whose own
error is 0. Its XYZ check now waits for the import to sample the ground
again once the globe's tiles have loaded.
Known differences that remain: a KMZ ground overlay is now imagery, so
ground fills draw over it where the old ground rectangle drew over them;
right after an import on ellipsoid terrain, pins can sit on the coarse
globe mesh until the ground is sampled again.
The full unit suite and the boundary, format and coupling checks pass.
In the browser, keyless: qa-geo-import, qa-geo-import-large and
qa-navara-geo-import pass; qa-geo-import-regressions fails only its
portrait-flight check, which also fails before the refactor.
Move Cesium viewer, map, sky, projection, trail and sonar internals into
its engine. Drive styles, bloom, sharpening and contact sonar through
engine.render. Count camera-input suspensions across all three engines
and migrate the feature callers. Preserve Cesium's effects and input
behaviour; fix transit lens clicks on Cesium and make zero sharpening on
Navara disable sharpening, as it does on Cesium.
Parse imported files into plain records and draw them through movers,
lines, ground and imagery on both engines. Follow Cesium's KML style
precedence, preserve local KMZ images and frame the drawable records.
Open overlays use imagery when the engine has no native map-overlay API.
Run every imported-display case on fake and headless Cesium engines.
The shared import path retains these known differences from Cesium's old
DataSources: wall fills, extruded prisms and gx:LatLonQuad are undrawn;
raised polygon fills drape while outlines retain altitude; GroundOverlay
rotation, altitude and RGB tint are not applied; rhumb lines become great
circles. Ground heights use the loaded surface synchronously instead of
waiting for most-detailed sampling. Supported KMZ ground overlays now
draw on Navara too. Document the limits rather than claiming full parity.
Combine batches B and C because their disjoint path manifests cannot
place the shared boundary and format files in a later commit while
keeping B independently valid. This combined commit owns the shared
docs, package boundaries, format scope, locale catalogs and coupling
baseline. Remove five obsolete import strings from all eleven catalogs.
Make the load-time source scan include new files and skip deleted paths
so the same checks work before and after recording the moves.
Coupling: Navara renderer lines fall from 1695 to 1294, Cesium import
files from 25 to 9, viewer lines from 1177 to 1026, SDK loads from 4 to 3
and engine-name lines from 62 to 42. No count grows.
The full unit suite and the boundary, format and coupling checks pass.
Browser validation remains to be run.

Use the keyless server for every check. Photoreal-only cases remain
unverified; do not enable paid tiles to run them.
Voice show_data_layers_menu opens the panel that holds the row, so asking
for Directions opens UTILITIES and reports that panel, not a hidden row
under Data Layers. In Cockpit the panel stays with Directions alone, as
Data Layers does; only Draw and Import step aside there.
Draw's options sit flat under its name instead of keeping the card that
hung under a DISPLAY button, and its Shape label no longer takes DISPLAY's
label column in other languages. Cyber marks Draw on with its red edge.
LayerPanel routing, the voice panel choice, and the panel's order, mode
and phone-sheet CSS gain tests that fail on the earlier code. The form-field
and segmented-control gates open Utilities for Draw's controls, measuring
Scenes and Utilities in turn since the left rail fits one tall panel.
README, CONTRIBUTING, the PR template, CURRENT-STATE and comments now say
UTILITIES for Draw and Import and list the Audio group, and two files
outside the format scope lose an unrelated reflow.
UTILITIES becomes its own panel in the left column, after Data Layers and
CCTV and above Scenes. The layer panel renders the Directions row into the
panel's list instead of Data Layers, and Draw and Import move there from
DISPLAY with their ids unchanged. Radio, the other row under the old
Utilities heading, stays in Data Layers under "Audio".
The panel collapses and remembers its state like the other left panels; share
links do not carry it. It hides in clean view, recording and Cockpit, takes
the Cyber left-rail treatment, and sits collapsed in the phone's Layers sheet.
Voice focuses the Directions row in its new list. The Directions, Draw,
Import and form-field gates open UTILITIES to reach their controls.
Normalize GeoJSON ground footprints, preserve explicit KML track heights,
and tessellate ground paths before native loading. Validate coordinates,
geometry types and decoded image budgets before allocating native resources;
strip loader-sensitive metadata and settle deferred failures and cancellation.
Render static pins in owned billboard collections instead of walking tens
of thousands of point entities each frame. Refine nearby ground heights in
batches, isolate imported pins from height picks, and release owned resources
and point selections on removal. Use safe ray origins above a hidden coarse
globe and retain valid mesh heights outside the current footprint.
Frame complete geometry with viewport-aware nadir arrivals, including walls
and rotated overlays; respect camera gestures and accept document file drops.
Strengthen real-loader, native 3D Tiles, paint, clock and lifecycle coverage.
Addresses both P1 and all 25 P2 findings in the follow-up review of #1122.
- 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.

DISPLAY ▸ Import (and drop onto the globe) puts the person's own files on
the map as Cesium data sources, clamped to the ground, one color per file,
with a row to show/hide, fly to or remove each. Files stay in the browser
for the session.
KML/KMZ are sanitized before Cesium reads them (network links, remote
icons/styles, models, photo/screen overlays and balloon HTML removed; KMZ
images served from blob URLs), so an imported file cannot make the page
fetch anything. KMZ is read with a small dependency-free zip reader on the
platform DecompressionStream, with a zip-bomb limit. Bounded file size,
entity count and number of files.
Tests: src/data/geoFileImport.test.mjs, src/ui/geoFileImport.test.mjs.
Gate: scripts/qa-geo-import.mjs. The import half of #890.
