Vessels out of view move on every 250 ms so one coming into view is current;
vessels at the end of their fixes ask for no frames; nothing moves while the
layer is off; 2D views judge the half-pixel step across the view's width; a
re-floor redraws vessels where they are on the next pass.
Vessels between two fixes, and live vessels a host placement places, were
redrawn at most every 250 ms, and a frame was asked for only once a second.
With nothing else asking for frames the scene drew vessels at about 1 to
2 fps live, and none at all while the world clock played at 1x.
They are now redrawn every frame the scene draws, moved in place without
new allocations. After each pass the layer works out how far the fastest
drawn vessel moved on screen and asks for the next frame for when it will
have moved another half pixel, at least once a second while any drawn
vessel moves. A vessel crossing the view close up therefore glides, and
one far away lets the scene idle. A frame already asked for later is
brought forward when a vessel speeds up.
Satellite points were propagated once a second and held still in between,
so while the world clock plays faster than real time they jumped: at
1 min/s, about 45 px once a second at globe scale.
Each SGP4 call now keeps a sample of the satellite's inertial position,
velocity, gravity and its rate of change (src/layers/satellites/motion.js).
Every frame each shown point is reckoned from its sample to the world time
and turned into the Earth-fixed frame by the sidereal angle, so points
glide at any play speed. Core satellites still take a fresh sample every
second, and at once when the world time is 30 s from it (fast play, a
seek), which keeps every point within about 10 m of SGP4. Starlink extras
take their first sample as they load and are resampled round-robin, more
per frame the faster time plays (up to 2,000 a frame); a point more than
two minutes from its sample waits for the next one. Hidden points are
moved when shown again, and the tracked satellite keeps its per-frame path.
Measured at globe scale: at 1 min/s points move on every frame, 0.4 px a
frame and at most 1.4 px (before: once a second, 45 px). With 11,880
satellites (Starlink on) the scene holds 60 fps, frames 16.7 ms median and
19.7 ms p95; reckoning costs 0.02 ms a frame for 1,342 points.
A weather row's play started the world clock even with no time to show,
where there is no timeline; it now does nothing then, as the timeline's
own Play cannot be reached. A weather layer made without a weather clock
does nothing once destroyed, so enabling it after builds no clock.
The timeline's speed follows the world clock's rate whoever set it, and
its Play runs at that rate, so it and a row's play never run at different
rates; a rate not offered shows as the nearest offered speed. Choosing a
speed sets the clock's rate first, also while a driver steps.
Marks merge on their whole label and are cut for showing after, so two
whose labels only differ past the cut stay two, and the cut counts
graphemes (code points where the runtime cannot tell them), so an emoji is
never split.
Tests that compared a DOM element with null built an assertion message
from the element when they failed, which hung the run; they compare plain
values now, so they fail at once. The timeline tests put the clock back to
real time after each.
A weather row's play ran the world clock at whatever rate it had, and
going live set that back to 1, so the speed chosen on the timeline was
lost. The world clock now keeps its rate while paused and live, and the
timeline's speed sets it whenever it is chosen, so any play runs at it.
A row's play starts from the start of the covered time when live or at
its end, as the timeline's does, and does nothing while every product the
row shows is suspended, as its reduced-motion note says.
Live, the Weather panel's frame time is the newest of each product's
frames, suspended or not, so it no longer goes away under reduced motion,
on a hidden page or without an imagery host.
A weather layer made without a weather clock builds its own when first
enabled rather than when made, so a layer never turned on leaves the
world clock alone, and its own clock (createWeatherClock({ shared: false }))
leaves the world's time where it is when destroyed; only the last shared
weather clock sends the world live.
On the timeline, a zoom or a pan clears the hovered tick's label, a label
is never wider than the track and ends in an ellipsis, and a mark's label
is cut to 60 characters (WORLD_CLOCK_MARK_LABEL_LENGTH).
The changelog entry says what a row's step does, names the earthquake
layer's new exports and says it registers with the world clock.
A layer's world clock coverage may now give each mark as an object,
{ time, label?, id?, kind? }, as well as a bare epoch ms number, and the
two may be mixed. worldClock.coverage() keeps marks as the sorted list of
distinct times, so existing readers are unchanged, and adds markDetails:
the merged marks in time order (then kind, label and id), each frozen and
holding only the fields given. Marks given alike by several sources appear
once, a bare time is dropped where a labelled mark shares it, and a mark
with no finite time is ignored. The contract is documented in the
worldClock JSDoc and docs/APPLICATION.md.
Launches label their marks with the mission's name (the launch's where it
has none), cut to 27 characters in capitals as the mission index shows
names. Earthquakes of magnitude 6 and up label theirs with the magnitude
as the map shows it and the feed's place cut to 40 characters, such as
"M6.4 · 113 km SSE of Lata, Solomon Islands"; the layer now tells the clock
when the labels change as well as the times.
On the timeline, a pointer within 6 px of a tick shows its label over the
track (nothing for an unlabelled mark), and a tap there goes exactly to
the mark's time instead of the point tapped. A tap elsewhere and a drag
work as before, and ticks stay ticks. The arrow keys still step from mark
to mark; with the handle on a mark, its labels follow the time in the
handle's aria-valuetext, and show over the track while it has focus.
The timeline drew a tick for every registered mark, and the weather clock
registered every radar, satellite and lightning frame, which come every few
minutes, so the track was a wall of dashes and the arrow keys crept from
frame to frame.
Weather products now register only the span of their frames (start and
end, as before) with no marks. Holds, the gate and the next-frame wait
while the world plays are unchanged. A weather row's step param goes to
the previous or next weather frame (every shown product's frames, and the
row's own while it is suspended) rather than to the timeline's marks.
The Earthquakes layer registers with the world clock once, at init, and
unregisters on destroy. While on, its quakes of magnitude 6 and up
(EARTHQUAKE_MARK_MAGNITUDE) are marks, and its coverage is their own span,
or none without any, so it never stretches the timeline beyond the feed.
Off, it has none. It tells the clock when the set of marks changes. The
map still draws every M2.5+ quake.
Launches stay marks. With no mark ahead or behind, the arrow keys step
along the track as shown.
Built without a weather clock, the weather layer still ran a frame replay
of its own: params.play stepped its frames every two seconds and went round
from the last to the first, params.step and params.latest picked frames
locally, and the layer tracked whether it followed the newest frame. That
was a second way to move time.
The layer now builds a weather clock on the page's world clock when none
is passed, and destroys it with the layer, so every layer follows the world
clock and its params move the world clock as the timeline does. The local
replay, its timer, the follow-latest flag, the wrap to the first frame, the
timerActive diagnostic and the reduced-motion "manual history available"
message are removed.
The Weather panel kept a second time transport of its own: a slider, step
buttons, Latest and Play, backed by a replay in the weather clock that
stepped the observed frames every two seconds and went round from the last
to the first. The weather clock also attached itself to the world clock as
a driver, so the timeline's Play became that replay whenever weather was on.
The panel now shows the frame time only: the newest frame and its age while
live, the timeline time alone at a past time. The weather clock no longer
has setTarget, step, latest, play, pause or togglePlay, its state no longer
has playing, and it no longer drives the world clock. It still follows the
world time, registers each product's frames as marks the timeline's arrow
keys step to, holds its products, and gates the world's continuous play at
each next frame until it loads. weatherClock.world names the world clock it
follows.
A weather row's play, latest and step params move the world clock as the
timeline does: play toggles continuous play (from the start of the covered
time when live), latest goes live, and step goes to the previous or next
mark. The rail timeline component, which only the panel used, is removed,
along with its unused messages in every locale.
A pack of the world's settlements of 15,000 people or more (31,827 places,
1.6 MB, CC0) built from the Wikidata Query Service by
scripts/build-wikidata-cities.mjs. src/data/wikidataCities.js reads it on the
first lookup and answers the nearest city to a point, the cities around it,
a city by name ("Paris, France", or the nearest namesake in view) and a
country's name in the page language. Names match without accents or case.
The build leaves out groupings of settlements (metropolitan areas,
agglomerations) and places that no longer stand, keeps a city that is also a
narrower grouping kind (Istanbul) or a unit dissolved where nothing else
names the spot (the Vietnamese provincial cities of 2025), fills a country
from the area a place lies in, splits a population band the service cannot
answer in time, and fails if well-known cities are missing or a known
grouping gets in. The app never calls Wikidata itself.

The Rain radar, Lightning density and Satellite clouds rows named NOAA
nowCOAST until a manifest named its own source, whatever the source read.
A weather source may now supply sourceName(kind), kind being radar,
lightning or satellite; the row shows that name until a manifest names one.
The name is read once when the layer is built and held to the same rule as
a manifest's display.source. A source without names, or one whose name is
refused or fails, still shows NOAA nowCOAST.
The ./i18n entry exports t, tn, msg, translateKnown and the number and date
formatters. setMessageOverrides({ en: {...}, de: {...} }) shows the
application's text for any catalog key: in the active locale, else its
English, else Core's translation.
Live counts repaint the rows many times a second; the index now reads its
headings at most once a frame, and only when a heading changes. The label
goes before the tick when there is no room after it, as in a right-to-left
language, and the ticks sit at the panel's inline end.

- Escape in the field closes the search alone, focus back on its button,
without folding the panel or leaving the cockpit.
- The category is the group's key (LayerRows' data-group), so a language
change keeps it; a group that goes away clears it.
- On and Off follow whether the layer is enabled, not its feed's state.
- The filter is a disclosure of two groups of toggle buttons: opening it
focuses the chosen option, the arrows, Home and End move, Escape closes
it, and it stays inside the panel.
- No layers match is translated, the search matches names only, and the
rows are filtered once per frame at most.
- A voice request to show a layer the finder hides clears the finder.

The finder matched only the English name, so a search in another language
found nothing. Its header buttons and its bar share state through the
component's module rather than a global.

The group label is drawn on the page just outside the panel's edge instead
of over the rows; the panel clips what leaves it, so the label is teleported
to the body and placed from the tick. The finder shows focus as a soft ring
on the field's frame in place of the hard outline round the bare input.

The Data Layers panel gains a search field, an All / On / Off and category
filter, and a tick index down its side for jumping between sections. Both
sit beside the Data Library browse control.

The rail's buttons are disclosures (aria-expanded, aria-controls) and go
through one toggleCockpitUtility action, which already keeps one panel open.
Collapsing returns focus to the rail when the launcher's toggle is hidden.
The edge switch is gone: edge mode does not apply in the cockpit.

Cyber and the phone keep their own cockpit layouts. Display and Radio take
their top from the layout pass, whose floor now matches the left rail, so the
panel's height still stops short of the briefing. The rail keeps its physical
side in a right-to-left language, the Live Signals rows use logical sides,
and rules for the launchers' old strips, which the rail hides, are gone.

The restyle had dropped the page and its tab while the news section, its
fetch and the briefing tests still use it.

In cockpit the left rail now shows Data Layers only: Visual's rail item
and panel are hidden there, as Authoring and Utilities are, and the
cockpit's own Display panel stands in for it. The rules that trimmed
Visual's groups in cockpit are removed as no longer reachable. If Visual
was open on entering cockpit, the rail's sliding highlight no longer
stays where its hidden icon was.
