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.
Remove code that nothing in the app, the runners or CI uses:
- the one-off migration compare, look and bench scripts and the vector
ground prototype they measured, with the bench tables in the docs;
- the unused Navara-named shared render modules (polygons, ground picks,
mover bank, ground ring);
- the Cesium-shaped aircraft and vessel test renderers, and the trail,
engineFromViewer and horizon-occluder helpers only they kept alive.
Their tests now run on the production displays over the fake engine;
- Navara's unread diagnostics, fallback ports, dead exports and
parameters, stale effect-chain anchors and the unread capability flags.
The QA scripts share one keyless guard and readiness wait, the session
harness reuses the strict harness's browser flags and block list, and the
harness honours QA_ANGLE and QA_RESERVED_PORTS. The bikeshare fixture
keeps only what its scenario reads. The docs name the engine picker where
it is (VISUAL PRESETS) and drop dated run results.
No behaviour changes on either engine. Navara layer renderer lines fall
from 189 to 0 and viewer lines from 891 to 849.
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.

Layers are to draw through the globe contract on both engines, so Cesium
gets back the movers and lines removed as unused:
- engine.movers draws sprite sets as a BillboardCollection (atlas cells
cropped once per set), point sets as a PointPrimitiveCollection and
model sets as one Model per instance. depthTest, disableWithinM, order,
scaleByDistance, colorBlend, unlit and minimumPixelSize follow the
contract; a model's matrix is written in place, so instances no longer
share one scratch matrix.
- engine.lines draws each line as a polyline Primitive with width in CSS
px, geodesic arcs, dashes, the tactical and arrow materials,
depthFailAlpha and modelMatrix; a rebuild keeps its show, matrix,
colour and place in order.
- The picker returns the pickId a layer wrote last, skips sets that are
not pickable and instances behind the horizon, and falls through to
what lies under them. Surface samples can exclude mover sets again.
movers and lines move from the optional capabilities into the required
contract shape, and the contract suite always runs their checks.
- Navara 0.2.1 never frees pick batch ids, and the mover banks rebuilt
their instanced meshes on each attach, leaking about 260 KiB of
WebAssembly memory per switch. A per-view pool hands released ids back
out; the long soak now asserts native growth of at most 32 KiB per switch.
- Navara 0.2.1 sometimes drops the first show:false update on a new
vector layer, so a zone turned off right after a switch back stayed
drawn. Polygon displays hide by deleting their layers and rebuild them
when shown.
- Camera verbs drive both engines through the globe contract; the Cesium
viewer rig and the tests of states it can no longer reach are gone.
- Flights and military tracking share src/layers/aircraft/tracking.js.
- The geo import scenario reads movers only where the engine has them.
- Add the Navara section to docs/CURRENT-STATE.md and a changelog fragment.
- src/geo drops the ported debug argument checks and the tests that
bitExact already covers; package boundaries accept a directory entry,
so src/geo/ is listed once per group.
- Cesium no longer carries movers and lines nobody draws with: they are
optional engine capabilities. The fake engine and the Cesium camera use
the shared cameraMath; unused contract tables, clock.ticked, the
'finest' surface detail and Navara click statistics are gone.
- ALPR keeps one overlay core and one presentation model for both
engines, bikeshare one station bookkeeping, the Navara ground effects
one definition helper; image atlases, view centres, mover banks and
colours are shared.
- The legacy switch route, the clock offset and rate controls and other
unused exports are removed.
- The acceptance runs the Navara draw, geo import and scope checks;
scenarios use the harness switch and page helpers; the main chunk
check keeps the size budget only and runs once in CI.
