The contract suite is split into one module per area and grows from 87
to 114 checks, each named after the member it exercises: a gesture during
a flight does not cut it, a render request inside a frame draws the next
one, a pure rotation raises changed, ground corridors are as wide in CSS
pixels at device scale 2, imagery replans on resize, drapes draw only on
their surface, sampleTerrainMostDetailed keeps order and passes on a
rejection, terrainRevision changes on a new terrain and on fallback,
follows raise followChanged on retarget, and a mesh, a ground fill and an
imagery pixel draw the colour asked for. In the browser Cesium passes all
113 it runs at device scale 1 and 2; Navara passes 110 of 111 and reports
its single-colour mesh, drawn before tone mapping, as a known failure.
scripts/contract-mutants.test.mjs breaks one promise of the fake engine
at a time, 30 mutants in all, and names the check that catches each; the
list of contract members the suite never calls is down to five.
maps.errors reports tile and terrain errors where an engine has them
(the tileErrors capability: Cesium yes, Navara no), and the map
controller falls back to another map only where it does; movers.list()
rows tell whether a set is shown, as the other families do; FollowHandle
.name and PickResult.primitive are marked deprecated. qa-contract-suite
takes --dpr and the ANGLE backend from QA_ANGLE.
Layer display tests no longer re-check Cesium primitives in every layer:
they run on the fake engine, and one Cesium translation check per ground
kind lives in the Cesium engine's ground tests. Their harnesses are shared,
and the fake-engine, Cesium-engine and flights tests that repeated the
contract suite are gone, 340 tests in all.
The press-travel measurement is shared by the selection dispatcher and
CCTV, which loses its ScreenSpaceEventHandler shim and world-click module.
ALPR, installations and bikeshare share one selection keeper and selected
marker write. Layers with their own click rules keep their handlers.
Navara's pulse is a class like the ground pass, the ground and imagery
passes share the surface uniforms, and the colour, log-depth and occlusion
GLSL lives in one chunk module, each caller keeping its depth bias. The
ground suite runs inside the contract suite (--only=ground:), and fixture
and script names say what they test.
Behaviour is unchanged on both engines.
Draw launch-pad zones as radial ground discs with the original fill, rim,
transitions, emission and depth bias. Drape Transit history and its backing
on ground corridors. Keep the current age bands and once-per-second updates;
advance the active head with a reveal fraction and rebuild only at segment
crossings. Its wider dark edge and colour core blend once, as on Cesium.
Navara composes these looks after tone mapping.
Build reveal corridors and dynamic Transit history synchronously once shared
terrain bounds are loaded. Keep requesting frames until the visible globe
tiles and committed primitives are ready: classification needs current
surface depth after a camera move. Retain the reference radial material,
its alpha envelope and the head's material-only reveal updates.
Remove the empty Navara ground effect from the render chain when the last
shown set is hidden or destroyed. It otherwise remains as the insertion
anchor for later pulse effects after its packed textures have been disposed.
Cover reveal, destruction and replacement with fresh-state comparisons for
corridors, polygons, discs and cells. Cesium drawing is unchanged by this fix.
Keep the radial pixel check at a 500 metre radius and 4 kilometre view,
sample the brightest of six inner points around the native fill gap, and
sample across the rim width. Restore its view during arrival flights and
run it last among ground checks. Both suite launchers wait for the linked
view to arrive before checking. Keep these checks with the radial look.
Pass rectangular pick windows and drill limits through input subscriptions.
Street Level uses its 9 pixel window and CCTV uses its 14 pixel window and
six-result drill. Down picks stay synchronous, moves coalesce per frame and
Navara clicks keep the GPU answer from their gesture. Add a projector
ellipsoid option and use WGS84 radii reduced by 1,000 metres for Street Level.
These changes restore the original Cesium pad fill and ground trail rather
than the temporary ring and raised lines. Navara follows the same appearance
and horizon policy, and now honours explicit CPU pick windows. Existing
callers without these options retain their defaults. The four debts share
the contract, suite and engine implementations, so keep them together.
No coupling count grew or fell: renderer lines remain 0 and 189, external
Cesium imports 3, external viewer lines 891, engine-kind checks 1, engine
resolution calls 0, extension reads 3, ground passes 1, SDK loads 3, screen
handler files 4 and engine-name lines 32.
The contract and ground suites now wait until the camera has reached the
view in their link before checking, because the app's restore flight could
land in the middle of a check; that was also the cause of the intermittent
camera-events failure. The radial check uses a launch pad's size and samples
the fill at several inner points: Cesium's own old pad leaves the same gap in
a small ground disc's fill. The pulse-band check takes its base frame once
the surface has settled.
Checked in the browser, keyless: the contract suite passes on both engines
(84 and 85 checks), the ground suite passes on both, CCTV v2 passes 58
checks, and the space, transit, Street Level and CCTV engine switches pass.
The transit and Street Level scripts fail as they do before this change.
In the app the world overlay draws on a canvas of its own above the
globe, so letting every canvas take the pointer sent the suite's clicks
there. Only the engine's canvas takes it now. Without makeCanvas the
pick check's sprite atlas was a plain object no real engine draws, so its
sprites could not be picked; the page now hands the suite real 2D
canvases. --only=prefix,... runs a subset of the checks. With both, Cesium
passes 63 of 63 checks and Navara 66 of 66.
The app sets contact sonar on every frame (src/cyberSonarEngine.js), so a
value the contract suite sets never survives to its next frame inside the
app. qa-contract-suite.mjs reports such checks as skipped, naming their
owner, instead of failing them.
scripts/report-engine-coupling.mjs counts the engine-specific code left
outside src/globe/cesium and src/globe/navara: layer renderer lines per
engine, Cesium imports, `viewer` mentions, engine-name checks, raw Navara
reads, Navara ground passes, Cesium SDK loads and ScreenSpaceEventHandler
users. engineCoupling.test.mjs fails npm test when a count grows past
scripts/engine-coupling-baseline.json, so each step towards drawing
through the globe contract can only lower them.
scripts/qa-contract-suite.mjs runs src/globe/testing/contractSuite.mjs in
headless Chrome on the Cesium and Navara of a keyless dev server, which
until now only ran on the fake engine. The page imports the suite from the
dev server, starts at a fixed view, waits for the camera to rest and lets
the pointer through the panels. Cesium passes 57 of 57 checks, Navara 64
of 67; docs/CURRENT-STATE.md names the three that fail.
