Measured over the second half the heap still grew about 20 KiB per switch in the acceptance run (117.8 to 123.8 MiB from switch 250 to 500), so the narrower window did not separate warm-up from growth; the original check stays.
Under the soak workload V8's compiled code and the layers' caches grow for about 250 switches and then the heap is flat (121.4, 121.7, 120.4, 119.1 MiB after 250 to 400 switches), so a line fitted from switch 20 measured the warm-up. Over the second half the threshold stays 10 KiB per switch; the run before the layer effect fix measures 19 KiB there.
Layers re-create their ground effects on every attach. Navara's removePass leaves the EffectPass undisposed, so each switch kept its EffectMaterial in three's program and material caches, together with the uniforms' DataTextures and their Float32Array data (earthquakes: about 47 KB of buffers and one WebGL program per switch). engine.LayerEffectDesc now disposes the raw pass on delete, as the app's own effects do.
Asking the canvas again during the switch made the reuse depend on getContext at that moment: with new contexts refused (qa-strict-failure-matrix, cold Navara to Cesium) the rollback to the parked Navara threw and left no globe.
The aircraft scene binding re-tracked with origin share-restore, which stayed on the entity: a later trackedEntityChanged for it (cockpit exit, refocus) never stamped navigation, and the aircraft lost its selection origin. Flights, military and satellites now set a transient gevRestoring mark around follow.start, and the aircraft binding resumes with the origin the aircraft was selected by.
qa-strict-prod-smoke opens the keyless vite preview on each engine, switches once and fails on any page error. qa-strict-cold-chunks reports Cesium.js at a cold Navara start as a known gap instead of a failure.
This reverts ae13a56f. In the production build every 'cesium' import is the global that Cesium.js defines; with the script loaded only when a Cesium globe started, modules evaluated at boot (cesiumConstants, annotationEngine) threw ReferenceError and neither engine started. A cold Navara start loading Cesium.js stays a known gap.
The sprite and point mover shaders rate each contact by its anchor against the sweep with the cyberSonar.js sampler maths; the engine sonar scene feeds the theme, settings and shared sweep angle each drawn frame and keeps the fleet cadence only while the sweep runs over contacts.
The zone was a flat disc at ellipsoid height in Navara's opaque scene: it floated over low pads and sank under raised ground or 3D tiles, with hard edges and an unlit rim. A screen-space pass now paints the ground pixels within the radius of the pad from the scene depth, as Cesium's GroundPrimitive classifies them, using one style shared by both engines (LAUNCH_PAD_ZONE_STYLE).
The cockpit's weather feed moves out of the Cesium cloud pass and serves both: Cesium keeps its own cloud canvas, an engine with its own clouds takes their cover from the same observations, with no second WebGL canvas.
Navara draws its transparent scene after the post effects into a target without the scene depth, so stems and pack polygons and images painted through 3D tiles. A scene-depth test now drops each of their fragments behind the depth Navara packs after its opaque pass; they stay in the transparent pass, so their look in the open is unchanged (scripts/qa-edge-occlusion.mjs compares it with the previous build). Wind flow was already hidden and is kept as a guard in the same scenario.
postprocessing's BloomEffect runs after the overlays and before the visual styles, follows Cesium's eased strength and dead zone with its threshold set in display terms, and VisualEffects drives it when the engine has the bloom capability.
A motion drives one camera through a rig: a Cesium viewer's own camera, or any globe engine through camera.pose/setView/lookAt/release/transform/flightActive/following and frames.preRender. An engine rig binds its frame, canvas-input and follow listeners only while its motion runs. A finished once orbit now releases its lookAt lock, and an orbit armed through a flight keeps its nudge budget until it starts.
CRT, NVG, FLIR, Anime and Noir run their Cesium shaders through a GLSL prelude with the exact sRGB transfer, crossfade in the stage order, fade the Navara stars with Anime, and report the visualStyles capability through engineCapabilities.
It takes the ICAO a position row carries, in any case, or the marker id, and selects through the same path as a click; selectAircraft now delegates to it.
A flyover, a launch-site view, a cancelled flyover or another mission now clears the pending orbit framing, so a late TLE lookup followed by a data refresh never takes the camera back.
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.
Navara's transparent pass runs after the post effects without the scene depth, so a camera frame clamped in front of a wall still painted through it. scripts/qa-edge-cctv-occlusion.mjs serves a one-box tileset as a local fixture with no network and checks on both engines that the frame ends at the wall and is not visible behind it.
Sentinel-2 made the desktop source row wrap to two rows; the row now lays out every tile in one row (three columns on a phone, as before). scripts/qa-map-source-tray.mjs read the controller's removed imagery internals and counted five tiles between OSM and the styles; it now reads the live base provider and counts the section's tiles and engine picker. The five failures left also fail on origin/main e5d15f24.
The handoff test failed under a loaded test runner when the refined pass needed more yields than a fixed 5 ms timer allowed; it now yields until the refined paint lands (bounded by a task count, not wall time).
The Navara look stopped requesting frames once its globe is parked. scripts/qa-app-once.mjs now fails if anything moves a parked engine's camera or asks it to draw (its own resume aside).
A visual choice made while no globe is attached (a style key, a Display control, a voice command) is queued and applied to the next engine's settings after it restored the address's view, so the person's choice wins; reads answer from the released settings. The globe reset and a location lookup started without a globe do nothing, and the map-source chips and camera buttons are unbound until the next globe binds them.
