The probe exposes settled() and the first-frame outcome; scripts/qa/ready.mjs
waits for drawn frames with the camera at rest and for a pick at the click
position, with a deadline and its reason in the error. The strict scenarios
use these instead of fixed pauses and loading-screen polling, and the
hidden-switch scenario checks how the loading screen was lifted instead of
how long it took.
Each switch scenario now records a draw ledger per engine and runs a
contract monitor; both write to the scenario's evidence file only, with an
empty allowlist until browser runs show what differs on purpose.
A scenario whose body ran past about 19 s idled until 45 s after its
start, and twice one never exited and hit the runner's 300 s timeout
after it had passed: something of Chrome outlived Browser.close and kept
its stdout and stderr open.
- scripts/qa/browser.mjs closes Chrome within 5 s, kills its process
group and closes its pipes; the harness then finishes and exits with
the scenario's code. QA_EXIT_DIAGNOSTICS=1 keeps the old ending and
prints the open handles and Chrome's process tree 5 s after finish.
- Every strict page starts with its clock at the 18:30 UTC nearest to
the real time, so Navara's sun is up over the test cities whenever the
acceptance runs; a scenario can ask for its own instant or the real
clock (Wildlife does, for its freshness fixtures).
- The runner records a scenario that passed but did not exit as hung,
kills the whole process group on a timeout, runs a failed scenario
once more and reports one that passes then as flaky, and appends each
run to --history=FILE; scripts/report-acceptance-flake.mjs reads it.
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.
- 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.
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).
The shell's scene part detaches it too, so a candidate failing in a later part (a layer's drawing, Cockpit clouds) leaves the shell free for the working engine instead of refusing every later attach. StyleManager.attachScene releases what it built when it throws, and one detach runs at a time. The controls phase awaits its parts, and a failed attachment no longer forces handoff off for the parts it releases. scripts/qa-app-once.mjs now also rolls back from a Navara candidate whose layer attachment fails.
createStandaloneApplication opens its first globe, attaches the scene host and returns attachScene/detachScene: a switch hands the session off, parks the outgoing renderer and attaches the incoming one with its catalog to the parts the phases registered once. A failed candidate releases what it attached; the working engine attaches again on the same shell, voice, tools and stores. ?switch=legacy keeps the route that builds an application per engine for one release. scripts/qa-app-once.mjs now asserts identity, UI, tool and listener continuity, the rollback and the legacy route.
window.__gevSession names each session object by a stable instance id and counts applications, attachments and detaches. scripts/qa-app-once.mjs (report-only with --report for now) runs three round trips and a parked-renderer rollback on a keyless preview with paid map, model and voice endpoints blocked.
