Navara now matches Cesium where the review found it diverging: a flight
holds the camera inputs, camera.changed counts turns as Cesium does,
render requests made during a frame survive it, follow pinches zoom,
ground widths follow the pixel ratio and Cyber sonar reaches glyph caches
and models. On Cesium, a staged imagery swap keeps loading tiles, setView
replaces a running flight, and a cleared weather detail goes away.
The contract gains MoverSet.failed, maps.terrainRevision,
render.maxTextureSize and surface.sampleTerrainMostDetailed on every
engine, so layers retry failed models, key road heights by terrain,
size weather textures to the GPU and place Bhote Koshi cards on detailed
terrain.
Engine switches keep the live view, follows, focus, layer options and
cards: a pick hands over the exact pose, applies no address options and
pans no carried-over card; a history visit still applies its entry.
Layers put GhostMaps pins, cable landings, OSM Places and directions on
the measured surface without per-frame sampling, draw the Cockpit contact
dot, hide disabled CCTV on attach, and keep ALPR running outside secure
contexts. KML imports draw raised polygon fills, rotated and coloured
ground overlays and north-referenced icon headings, and report files
with nothing to draw.
QA scripts read the contract instead of Cesium internals (test:track is
109/109 again), wait for the camera to rest before clicking, and give
cold switches and parked engines realistic time. Docs follow the code.
Every Cesium read that a Navara page made was surveyed with the strict acceptance (GEV_QA_CESIUM_TRAP=record). Math on those paths now uses src/geo: screen annotations, weather and wind center readings, cyclone picks, scene data pack polygons and images (new navaraGeometry.js), the awareness subject, the orbit offset of camera verbs, voice frame_overhead, the agent world packet and Directions colours and ground picks. The celestial ring's Sun and Moon come from a bit-identical port of Cesium's Simon1994 model, JulianDate and TEME rotation (src/geo/simon1994.js, julianDate.js, transforms.js); a Cesium globe still applies its ICRF rotation once loaded.
Traffic, Street Level, the Nepal event and locator and geo import build on Cesium's math or entity model on either globe; their enable (or the import) now loads the SDK first through src/app/loadCesium.js, synchronously when it is already there. A production page guards the global so a missed read is reported and starts the load. No module reads Cesium while it loads (scripts/check-cesium-load-time.mjs, run by npm test). Cesium.js is still loaded by index.html here.
