Main's new layers (drone airspace, OSM places, sea marks, ski pistes) are
Cesium-only for now: they join the layer directory and the Cesium catalog,
are built afresh for each Cesium catalog, and show as unavailable on Navara.
The zoom-out guard is a scene part that attaches to Cesium globes only. The
awareness range pulses and their echoes draw on Cesium through the awareness
display's viewer; Navara keeps the plain range ring. Camera-input wakes go
through the display, and the analyst keeps the session-owned memory with
main's area presentation. A disposed voice runner aborts work in flight, and
an engine switch still keeps the last answer.
Modules main added that read Cesium while they load (zoomOutGuard,
awarenessEcho, the ground-sampling scratch in localGeojsonCore) now build
those values on first use or use src/geo, so a Navara page still starts
without the SDK. The OSM view box reads the engine's view rectangle.
Main grew its own main chunk by 93,873 bytes gzip-9 since the merge base, so
the baseline is raised to the merged size.
Every scenario runs through scripts/qa-strict-harness.mjs: each page, frame and worker gets an ordered block list before it runs (paid hosts and routes first, then only the preview, declared fixtures, keyless probes and cached free tile hosts), switches with real input on the picker, and records its assertions per layer and engine. The runner reads the catalog from the live page, fails any layer without an assertion on either engine, can build and serve a keyless checkout itself, and adds rapid, hidden-tab, context-loss, failure-injection, cold-chunk and soak scenarios. The main chunk gets a 1% size budget.
