A picked engine now lives in the switch until it runs; only then is the
address written, so a pick superseded by Back or one that fails rewrites no
entry. An engine-changing history visit holds the outgoing share link, which
neither restores nor writes the visited entry, and the running engine takes
the address back once the switch settles, restoring any entry visited while
it was held or not yet listening. Handed-off layers keep running where the
incoming address agrees with the outgoing one and follow a visited entry
where it differs. A failed recovery keeps the error on the loading screen
with an engine picker for a retry, and a failing reveal of the new globe no
longer blocks the cover removal or later requests.
qa-all-layer-switches.mjs now checks once that Puppeteer can start Chrome and that the preview answers, and names PUPPETEER_EXECUTABLE_PATH and npx puppeteer browsers install chrome when it cannot. Each run writes <output>/acceptance.json with the commit, dirty files at both ends, Chrome, Node, base URL, times and, per scenario, status, exit code, duration, covered layer ids and the sha256 of its log. It replaces summary.json.
Live Sentinel-2 imagery is bright at this altitude, so a fixed crop of white two-pixel vehicles changed anywhere from 14 to 300 pixels. The scenario now serves a uniform dark ground tile, waits for the layer to settle with vehicles in view, projects each vehicle to the window and requires 90% of those above the drawn terrain to change the picture where the layer places them; in simulation nothing else may change. Vehicles below the terrain and the population left after the round trip are reported, not asserted.
The engine switch moves out of main.js into src/standalone/engineSwitch.js: every
engine change in the page hands the session off (layers, Director, Contacts,
directions and satellite cameras), whether it came from the picker or from
history. Each attempt has a generation; a failure rolls back to the last engine
that started, requests made during a switch or recovery are reconciled once it
settles, and a picked engine adds its history entry only after it starts. The
first-frame wait only lifts the cover and never fails a started engine; a
hidden tab does not wait. Nothing starts after pagehide, and a failed recovery
leaves the picker usable.
Preserve the camera, map source and layer selection across engine sessions. Restore the previous engine if startup fails and retain local history navigation.
Remember the chosen engine and restore the current view after navigation. Keep the standalone JavaScript UI and retire the Dioxus migration and Cesium removal milestones.
Directions, the Contacts marker and panel, placed annotation labels, the
drawn-line measure, the Cockpit and formatRouteDistance each chose the unit
and precision on their own, and most chose before rounding: #1450, #1433 and
formatDistanceText or kilometreDigits from src/data/distanceFormat.js, which
cut after rounding. Each keeps its own metre step and rendering.
That also fixes the 10 km cut the Contacts marker and panel, the drawn-line
measure and the Cockpit still had (9,960 m read 10.0 km). The helper returns
kilometres already rounded, so the plain marker and the localized panel no
longer disagree on half-tenths such as 1,450 m.
A negative annotation distance now leaves the label without a distance, and
a drawn line with a coordinate that is not a number shows no measure, rather
than printing 0 m or NaN km. The HUD altitude tag and the spoken view height
keep their own unit choice.
Since the UI moved to single-file components, every unit-test process
compiled the views it imports from scratch, and the loader ran off-thread
(module.register), adding a round trip to every module a test imports,
including the ones that are not components. Core's unit tests took about
twice as long, and a host running Core's suite on smaller runners passed
its CI time limit.
register-vue now installs synchronous hooks on the loading thread
(module.registerHooks). Compiled components are kept in the system temp
directory, keyed by the file's path and text, the Vue version and the
loader's own code, so each one compiles once across test processes; the
compiler itself loads only on a cache miss. Cached modules run as code, so
the directory is used only when it is a real directory owned by the current
user and writable by no one else; on Windows it lives in the user's local
app data instead of a temp directory that may be shared. The cache never
sits inside the package tree, and GEV_VUE_CACHE=0 compiles every time.
On four cores the full suite went from 441 s to 240 s from a cold cache.
The transit, ALPR, vessel, CCTV and flight/military context fixes each
wrapped 359.5° to north with an inline Math.round(x) % 360. They now call
roundHeadingDegrees in src/data/headingDegrees.js, which also wraps negative
and multi-turn bearings. normalizeHeading moves there with it, and
cockpitMath re-exports it so existing imports keep working. It now adds a
turn only to a negative remainder, so a bearing just under half a degree
keeps its precision.
The awareness, Local ADS-B, cockpit wind, cockpit heading and Street Level
readouts use the same helper. The Cockpit's TRACK ACQUIRED signal rounded
without wrapping and could read COURSE 360°; it now uses
formatHeadingReadout, which shows --- for a track that is not finite.
The application package boundary owns src/i18n/locales/ar.json beside the
other catalogs, and the style.css shim test checks that the shim holds only
import statements rather than counting its lines, so adding rtl.css to it
does not read as rules.
Selects pad the chevron's side with padding-inline-end, as do the Radio
filter, the SDR gain select and the voice timeout select, which set their
own padding; rtl.css moves the chevron to the left, where an Arabic field's
text ends. A rail legend's range keeps left-to-right order under its colour
ramp, which always runs low to high from left to right.
Main moved the UI to Vue views and Pinia stores, so the Arabic changes to
the old DOM controllers now live in their views: the rail legend range
comes from formatScaleRange (keeping units a source supplies as given),
the voice timeout options are worded by Intl unit formatting in
VoiceControl, and the scene editor's JSON fields stay left to right in
SceneDialog. Main's CCTV status line, launch panel and calibration values
keep the Arabic isolates and Western-digit formatting.
isolate() and keepCodesWithValues() read the locale through getLocale(),
which follows the page's vue-i18n instance, and the Intl formatters take
intlLocale(getLocale()). A language switch now applies in place, and
applyDocumentLanguage sets <html dir> on every switch, so the page mirrors
without a reload.
The icon rails and their tips are placed with logical properties, so they
stay on the outer side of the mirrored stacks; Cyber's new stack offsets,
padding and edge lines are logical too, and rtl.css moves Cyber's right
stack to its new rail clearance. Main removed the Context mini radio, so its
right-to-left rules and test go.
The Arabic catalog gains main's new strings and drops the ones main no
longer uses; the other catalogs keep main's new keys and the branch's
landing labels.
