Cesium stops its render loop after a render error and offers only a
panel that dismisses itself, and a lost WebGL context never draws again,
so the globe froze or went black while the controls kept responding.
The scene chrome now shows an alert dialog with the error. Retry restarts
the render loop and keeps the notice until a frame renders without an
error; after a lost context it reloads the page, whose address keeps the
view. Reset view opens the app root without the restored hash or share
path. An inline conversation panel never reloads its host page. The
application viewer turns off Cesium's own panel; other callers keep it.
Review follow-ups for the globe-in-view recovery and voice limits.
- Leave a camera flight in progress and a playing Director scene, holds
included, to their own framing. The recovery is now installed with the
scene tools, which own the Director, and reads its running state.
- Reuse a voice turn's half-degree proof only from the position and
direction it was proven at, so a release that moves the camera checks
the turn again.
- Share one free-globe-camera check between the recovery, the voice
turn limit and the globe rotation.
- Keep an enableLook setting other code makes after the free-look limit
is installed, instead of writing back the install-time value.
- Name the nudging test for what it asserts, the 1% floor, and document
that a view losing its surface without a camera move waits for the
next one.
From the whole-globe view the camera could end up facing empty space with
only stars on screen. Cesium's free look (Shift+drag) turns the camera in
place, and from 18,000 km the planet's edge is only about 15 degrees from
nadir, so a few drags turned it out of frame. The rolled pose was then
saved into the share hash, so a reload or shared link opened on stars too.
- Allow free look only below 1,000 km. Orbit, tilt and zoom are unchanged.
- Measure how much of the frame shows the planet's surface by casting a
32x18 grid of view rays at the WGS84 ellipsoid. While the scope mask is
on (the default) only the rays inside its keyhole count, since the mask
hides or dims the rest of the frame.
- When a camera move ends above 1,000 km with no ray on the surface, turn
straight down at the same position and heading. Limb glow and a sliver
up to about one grid cell thick can count as out of view. The end of a
move comes from Cesium's moveEnd and from a check of its own that
samples the pose every 250 ms after moveStart and acts once it has held
for half a second: at some of these poses the camera drifts by a
rounding error every frame, so Cesium never sees it stop and never
raises moveEnd. The zoom-out guard from #1522 keeps wheel and pinch
zoom-outs in view; this catches the other ways a move can end looking
away, such as a saved or shared view that did, or a
drag that Cesium turns into an in-place look below its 7,500 km
trackball height (one that starts on the stars, or a tilt drag with the
screen centre off the planet). Views with more surface, tracked or
locked cameras and the 2D and Columbus modes are left alone.
- Voice tilt and in-place turns of a free 3D globe camera above 1,000 km
stop when about a tenth of the frame still shows the planet (or about as
much as it showed when it started, two grid cells of sampling noise
allowed), never below about 1% of the visible frame; a view that already
shows less only keeps or gains what it has. A turn that cannot go half a
degree further without crossing that limit is refused with a reason
instead of reported as done, and a turn it accepts turns at least that
half degree. A turn that keeps or gains surface is not refused, even
after the window has been resized, except that near the limit, where the
planet's edge crosses the sample grid, sampling wobble can occasionally
refuse one (most often above about 15,000 km and on phone or ultrawide
frames); nothing then turns away from the planet. A turn that starts
where the last voice turn left the camera keeps that turn's limit, or a
higher one if the planet now fills more, so repeating the request does
not take any more; once anything else has moved or turned the camera, a
turn is measured from what is on screen. A request made while the camera
is tracked is judged by the pose voice's release of the follow camera
will leave, before that release, so a refused turn keeps the tracking.
The frame measure and the look-step limit live in src/globeInView.js,
shared by the viewer and the voice camera verbs.
Core told time eight ways: Date.now() in most layers, JulianDate.now() for
flights and military, Cesium's clock frozen at page load for the sky, the
weather clock for observed imagery. They now read one clock,
src/time/worldClock.js, exported as ./time.
Live is a mode, not a timestamp: while live the clock is the wall clock,
so every layer draws as before. Away from live only the layers that follow
the clock move with it. The weather products follow it, as they followed
the weather transport; a host opts others in with follow(id).
- The weather clock takes its time from the world clock and drives its
replay, stepping its frames as before.
- Satellites, launches, flights and military (still 30 s and 15 s behind),
transit, GNSS, Recent Imagery, street level, the HUD and the celestial
ring read worldTimeFor(id). Cadences stay on the wall clock.
- Cesium's sky (stars, sun, moon, atmosphere, lighting) draws at the world
time each frame instead of the moment the page loaded.
- Weather frames and satellites declare coverage() for a host's timeline.
Choosing a language in the picker now applies it at once. The choice is
stored and ?lang is kept in step through replaceState, and the picker keeps
focus.
Code that writes translated text itself re-presents it on a switch:
onLocaleChange() lets an owner listen, removed at teardown, and status
writers hand over a function of the locale (voice cards, scene director,
SDR, draw hints, imagery split, map sources, Bhote Koshi media) so the
words are rebuilt rather than re-sent. The HUD, cockpit, radio, CCTV,
launch, awareness and credit texts follow the same hook, and
applyDocumentTranslations can be applied again without undoing text code
wrote since.
The unsaved-work registry and persistLocaleAndReload existed only to guard
the reload, so they go, with their catalog entries.
Replace the semantic keys with the English source text, so code reads as the
UI does and English needs no catalog: t('Save keys'), tn(count, one, other)
for plurals, msg() for text stored in data, and bare data-i18n* markup that
translates the element's own English. Other languages are one flat JSON each.
- Simplify src/i18n: drop namespaces, the configurable locale pair
(GEV_DEFAULT_LOCALE / GEV_SECONDARY_LOCALE) and its build defines. Locale
comes from ?lang=, the stored choice, then browser languages.
- Add scripts/i18n.mjs (npm run i18n): extracts every message from t/tn/msg
and markup, and fails on missing, unused, placeholder-mismatched or
wrongly-shaped plural entries. npm test runs it via catalog.test.mjs.
- Add Russian (src/i18n/locales/ru.json, 833 messages), started from the
community catalog in #312 and reviewed against the current English.
- Fix data-i18n placed on parents that would wipe their children (cockpit
LEVEL and local weather cells, first-run EXPLORE MANUALLY tile), and a
doubled degree sign in the TRACK ACQUIRED signal.
- Rewrite docs/TRANSLATORS.md for the new workflow; drop sections the earlier
merge resurrected in docs/CURRENT-STATE.md.

Without a browser key, the app asks its server for a short-lived Google
access token (GET /api/google/tiles-token, answering accessToken and
expiresAt) and loads Photorealistic 3D Tiles directly with it as a
header. A tile refused for an expired token gets a renewed one and is
retried once. A server that does not offer tokens changes nothing: the
app continues through ion or the keyless globe as before.
Route every application-owned presentation string through the i18n
core: t() call sites across the app/layers/ui/data/voice surfaces,
data-i18n* attributes in the src/ui/templates/*.html markup (applied at
boot by applyDocumentTranslations from src/standalone/application.js),
and the dock locale selector (runtime-rendered from the offered pair —
a single EN button while only English ships).
Rebased onto current main, where the extraction follows the module
splits: the shell wiring now lands in the owner modules
(panelChrome, visualSettings, locationNavigation, shareRestoration,
shellFeedback, applicationShell) and the voice status corpus in the
realtime* modules; scene status lives in director.js +
playbackAdapter.js.
Modules shared with the node runtime (loadingFeedback,
installationFeedback, regionalModel, keySetupCore, vessels ingestion)
stay environment-neutral English and localize at their browser render
sites (chip maps in shellFeedback/installations controls, the weather
table in cockpitBriefing, keySetupRequirementEnvVars compositions), so
the package-boundary graph stays clean; the browser boundary groups
now own the i18n modules they reach (scripts/package-boundaries.json).
