Between real time and an hour a second there was nothing to watch a few
minutes of weather or a launch play out at. The speed menu now offers a
minute a second as its second choice.
The zoomed track now drags: the handle still drags the time, while the
track around it drags the view along (or the time, with all of it shown),
a tap goes to the time under it, two fingers pinch it, and a sideways swipe
or a shift-wheel drags it too, the same with a mouse, a trackpad or a
finger. A view dragged off the handle stays put until the time moves.
Play moved in steps: the world clock told of its time four times a second,
so the handle and the globe jumped, and play stopped at every weather frame
while it drew, loaded ahead or not. The clock now tells of its time each
animation frame, and play no longer waits on the frame it is at: that
frame loads as play goes on, and play holds only at the next frame while
the one before it still loads. Weather loads its next frame ahead while the
world plays too, tells its listeners of frames as they change rather than
every frame, and the sun and moon move on each minute of world time.
Play holds while a layer loads the frame for its time, and the bar's only
sign of it was a faint pulse, so a stopped handle read as a stall. The
bubble now shows a small spinner beside the time while play is held. It
comes on once a hold lasts long enough to notice and stays through a run of
slow frames, so neither a quick frame nor the gaps between frames flash it.
With layers of very different reach on together, a month of launches and
a few hours of lightning, the short-range ticks were crushed at the end of
the one shared track. Scroll or pinch on the track now zooms it around the
handle, plus and minus zoom from the keyboard, and zero or a double-click
shows it all again. Everything still plays together; zooming only changes
what the track shows, and the view follows the handle as it plays, steps or
is left behind by now. A scrub's live edge goes by the stretch shown, so a
zoomed track can land minutes from now, and a double-click or pinch puts
back the time its first press moved.
Play no longer runs ahead of the data. The world clock gains a wait, which
holds continuous play where it is while a layer loads what the time needs,
and a gate, which keeps play from passing a time a layer has yet to load.
Weather gates play at its next frame and waits there until the frame shows,
so every frame is seen however fast play runs; it waits no more than eight
seconds on a frame that never comes, and takes a wait only when its frames
change. Play pressed while a frame loads waits for it too. A scrub still
drops what loads and moves on.
The bar loses its long date and the dates at its ends: the time rides in a
bubble over the handle, which pulses while play waits, and the bar runs
left to right in every language. Play starts at real time.
A speed menu beside play offers real time, an hour, a day or a week a
second, a day a second to start with. A speed chosen while playing applies
at once; chosen while weather's own replay steps its frames, it takes
playback over from where it is. Play starts again from the top only at live
or at the very end, so a pause just before the end plays on. On phones the
menu sits beside the track, a full-size target.
Cesium sets no limit, so zooming out left the globe a speck among the stars.
On the globe a hand now stops zooming out where the globe spans 30% of the
screen's height, which follows the screen's shape as the app's own
whole-globe view does. A camera already past it, after a flight or a turned
screen, stops there rather than jumping in at the next zoom. Flat maps keep
zooming out unlimited.
Away from live, a launch shows from its lift-off on: its marker, label,
paths and orbit stay hidden while the world time is before it, so scrubbing
or playing brings the launches up in the order they flew. The selected
mission stays whenever it flies, and live shows every launch as before.
Play on the timeline runs the whole track in about a minute, from its start
when at live, and runs the clock itself past weather's own replay. It goes
live when it reaches now, or holds at an end that lies ahead of now. Going
live puts the rate back to 1.
The timeline shows whenever a layer with time to show is on, live or not.
Its track runs over the time those layers cover, reaching to now, with a
tick for each launch or frame and a handle to drag; arrows step between the
ticks, and a scrub to now goes live. The bar sits along the bottom of the
screen, and the dock and everything anchored above it rise by its height;
clean view, recording and the cockpit put it away with the dock.
Layers whose data has a time of its own follow the page's world clock from
the start; live feeds such as flights, military, vessels and transit stay
live. Launches register the span of the launches loaded, so turning them on
brings up the timeline. Each timed layer registers its coverage once and
reports none while off, telling the clock after each step has settled. The
launch feed keeps its own window, and an orbit ring is drawn again once the
world time has moved far from when it was drawn.
The catalog stored the designator on satrec.intldesg for
internationalDesignatorYear, while the active-TLE lookup parsed the same
columns with tleLineLaunchYear. Each catalog entry now keeps launchYear from
tleLineLaunchYear, which moves to src/sources/tle.js beside the other TLE
field readers, and internationalDesignatorYear goes.
A blank designator now reads as an unknown year in both lookups; the
active-TLE lookup read it as 2000.
The traffic timing test starts a Vite server rooted at the package, which
wrote its dependency cache to node_modules/.vite and kept writing after the
server closed. A host running Core's suite then finds files inside Core and
its check refuses them. The server now uses a temporary cache directory,
removed afterwards, and skips dependency discovery, which the SSR-loaded
modules never need.
The HUD place-lookup changelog note credits its PR, #1459.
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.
UiRail takes `collapsible`: while no panel on its side is open, each item
shows its icon and label as a pill, and once one opens the labels fold away
to the icon rail, making room for the panel. The tip is not shown while the
label is on screen; the button keeps its accessible name and the visible
label is hidden from assistive technology. The side panel rails turn it on.
Each rail is now placed by its screen-side edge, at the rail clearance, so a
rail that widens grows toward the middle of the screen; collapsed, it sits
6px outside its stack as before.
The bar now needs more than the world clock being away from live: a layer
that moves with the clock must be on with time to show. In Core that is
weather radar, satellite or lightning with frames; a host adds layers by
following them. Turning the last one off hides the bar; turning it back
on brings it back.
The world clock reports this as `supported` in its state. Weather products
register their frames as coverage one by one, suspended or not, so the way
back to live stays on screen with reduced motion. Weather refreshes and
satellite catalog changes tell the clock their coverage may have changed.
A coverage that throws counts as none, and the clock reads its state once
per notification round.
A bar above the command dock, like a video player's: play and pause on
the left, the world time's date and time in UTC beside it, and Live to
return. It stays hidden while live, so Core looks as before until weather
history is scrubbed or replayed, a host moves the clock, or a link made
away from live is opened. Adds the pause and play_arrow glyphs and the
strings in every catalog.
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.
Field 28, worldTime, holds the world time of a link made away from live:
zigzag seconds since 2026-01-01, like field 8, but it may lie ahead of the
link's creation (a forecast moment). Opening such a link pauses the world
clock at that time; a link without it leaves the clock alone, so a page
opens live and Back or Forward does not stop a replay. Times no JS Date
can hold are dropped.
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.
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 panel now renders from the CCTV store, so the meta line is no longer
written to a DOM node by _renderCctvState. Assert on presentCctvPanel's
meta text instead.
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.
With the panel rails, the left stack's red edge line stood alone beside
the rail whenever no panel was open. It now shows only while a left panel
is open, and the right stack gains the mirrored line for its open panel.
The right stack takes the line and its gap without moving its panels, so
its rail sits outside the line like the left one.
A tall panel moves its stack to the focus or tail layout, and the rail
inside the stack went with it, so the Data Layers and Authoring buttons
jumped up and the right rail followed. Each layout pass now offsets the
rail back to the resting top, with the same transition as the stack, and
the right rail lines up with the left rail's buttons. Cyber pins the left
stack's top, so it flags that and the rail takes no offset.
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.
Every data-i18n, data-i18n-title, data-i18n-aria-label and
data-i18n-placeholder marker in the Vue templates becomes a t() call with
the key the boot pass used to look up, contexts included. The three labels
the shell rewrote at boot (Visual Presets, Location and the standby
description) render through t() too, and that rewrite is gone. With the
locale in vue-i18n, view text now follows a locale change, and markup
under v-if or v-for no longer comes back in English when it re-renders.
Rendered text and attributes are unchanged in every locale. The boot pass
still translates static page markup such as the loading screen and a host's
own markup, and npm run i18n rejects data-i18n* in a Vue template.
The application views install one vue-i18n instance that holds the active
locale and the catalogs. src/i18n/index.js stays free of Vue: bindLocale()
keeps its locale in the instance's ref, so t(), tn() and the Intl formatters
read it from there and a view that translates while rendering renders again
when the locale changes. A tag written straight to the ref is normalized.
Message formatting, catalogs and call sites are unchanged, and switching
language still reloads the page.
The instance outlives the views: unmounting one no longer disposes it. The
browser build defines vue-i18n's feature flags and drops its message
compiler, which Core does not use.
The Vue and Pinia migration's entries move out of CHANGELOG.md into
changelog.d/0000-vue-and-pinia.md, newest first, as the contributing guide
asks. 0000 stands in for the pull request number until it is opened. The
migration plan's cleanup step now records where it stands: the template
expansion is gone, the pattern is required for new UI, the page-level
markup tests render the real views, the attribute translation pass waits
for vue-i18n, and a host panel registration API waits for its first host.
CONTRIBUTING gains a Building UI section: new UX elements are Vue
components rendering a Pinia store their owner publishes to, portable
owners stay framework-free behind a publish option, controls come from
src/ui/kit first, controllers don't bind the DOM by hand (Teleport where a
view renders elsewhere; body classes, focus, same-task measured positions
and painted surfaces stay imperative), text goes through t()/tn() with
msg() for stored English, and tests mount components. The README and the
architecture summary drop the stale vanilla-JS claim, the UI ownership doc
points to the guide, and the migration doc's UiPanel note names
v-panel-state as what draws a panel's collapse.
The Cockpit display portal publishes the Display popover's slots to the
gev-display store while Cockpit is on, and the Display panel teleports its
HUD, Detection, Parameters and 3D groups into them and back, each only
while its own slot is published. The portal no longer moves the groups:
it keeps each surface's scroll position, puts back focus the move
dropped, and lays the surfaces out once Vue has moved them. The popover's
uses-shared-display-controls class renders from the store, and the right
rail no longer re-homes the parameters panel the markup already places.
PanelChrome, its collapse-preference restore and the phone shell read a
panel's disclosure state back from the gev-panel-chrome store
(_shownPanel), falling back to the markup's classes before the panel is
first presented, instead of reading the classes v-panel-state draws. The
share link and the phone shell share one rule for a panel the person keeps
closed (prefersCollapsed). The rails, the accordion and the hover
disclosure still read the classes, which the directive draws in the same
task as their layout.
The Cockpit layout pass publishes the utility strip's fit to the
gev-cockpit store: the HUD's --cockpit-utility-* lengths, whether only the
expanded control fits, and whether a collapsed control beside an expanded
one is hidden from assistive technology. CockpitView renders the lengths
on the HUD and CockpitUtilityControls the strip's class and each control's
aria-hidden, which now also follows a popover opened between passes. Focus
leaves a control before the strip hides it. Exit publishes no layout,
which also clears the expanded height, class and aria-hidden the old exit
left behind. The briefing and Contact cards' positions stay imperative:
the same pass measures them straight after writing them.
VisualSettings publishes the active style's parameter rows to the display
store, and the Display panel renders them with the shared row component;
a moved slider goes back through the store's setStyleParameter action.
The readout snaps a value to its step as the browser does, half-steps up
and an off-grid maximum down. A preset that resets the shown style's
uniforms republishes its rows, input for another style's parameters is
ignored, and a stopped owner takes its rows with it unless a newer owner
has published since. createStyleParameters is deprecated and builds its
rows the same way.
RecordingControls publishes the safe frame a recording composes in, 16:9
or 9:16 (null while none records), to the new recording store, and the
scene chrome renders the overlay's active and ratio classes from it
instead of the controls writing them. Any frame but 9:16, even none named,
records in 16:9 as before.
LocationControls presents whether the search field is open and whether a
lookup runs, and the dock renders its expanded and searching classes and
calls toggleSearch(). The lookup, the navigation's settle, Escape and the
location tray's collapse reach the field through the controls
(setSearching, settleSearch, closeSearch) instead of writing its classes.
LocationControls no longer takes searchToggle, LocationSearch takes
setSearching and NavigationController takes settleSearch in place of
searchInput.
The top-center and cockpit reset buttons call the location controls'
new reset() through the globe actions store, and render a reset under
way from it, instead of the location controls binding their clicks and
the navigation writing their labels. The store keeps each owner's reset
under way like its clear, and controls replaced mid-reset keep it on the
buttons. LocationControls no longer takes resetButtons.
