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.
- 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 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.
