A dataset layer loaded its features once and kept them until it was
removed: the parsed set survives disable/enable, so NWS alerts, GDACS and
EONET showed what they held when first switched on for the whole session.
A library dataset now asks the manager for a refresh every cacheSeconds.
Once its data is that old it loads again, and swaps the new set in only
when it is ready, so the old features stay drawn while the request runs
and stay if it fails. An enable after cacheSeconds also loads afresh.
Disable and destroy cancel a refresh in flight.
The dialog is now DataLibraryDialog.vue (with DataLibraryCard.vue for each
entry), placed with the Browse button by DataLibraryBrowse.vue in
LayerPanelsView and teleported to the body. It renders what the
gev-data-library store holds and sends clicks and typing to the owner.
src/ui/libraryBrowser.js is now the framework-free owner: it presents the
open state, filters, the rows they show, the stat summary and Remove all
through `publish`, and its controls answer the view. Its text helpers are
what the view renders with t(), so every label follows the locale without
rebuilding anything. Only showModal/close and focus moves stay imperative;
focus returns to Browse also when the browser closes the dialog on Escape
itself.
Component tests mount the view over the real owner (open, filters, Add to
Remove keeping focus, Zoom, Remove all, a language switch, clean view).
- Share links: the compact /share/<code> format carries the switched-on
library entries (field 29), so Copy Link keeps them; a share opened in the
same tab restores them; any share decides what is on, so one with every
library entry off no longer switches on the recipient's stored entries.
- A tile entry too dense at its minimum zoom (Norway cadastre z14, depth z11)
is hidden below that scale via minimumTerrainLevel instead of allocating
millions of tiles when zoomed out.
- EPC partitions keep the full extent for exclusion and the 98 % extent for
ranking only; the old trimmed-only extents are retired.
- Partition index footers that fail transiently are retried; an incomplete
index is never cached as complete, a complete prior index is kept, and it
is rebuilt after five minutes.
- Views that leave touching partitions unread are partial; listing and
footer bodies are capped and ranges validated.
- The Browse dialog relabels after a language switch.
globe.getHeight is a ray cast against the drawn tile's mesh and
scene.sampleHeight a GPU depth render; several layers asked for them
uncached and unbudgeted. The cache written for Transit moves to
src/services/terrainSurface.js and is handed to every layer through the
ground service, so layers share one cache and one read budget.
- Rail reads each train on a ~4 m grid instead of every frame.
- Local data layers read terrain floors through it and stop depth samples
at 8 ms a frame.
- Bike Share draws stations at once and finds their heights afterwards in
4 ms steps.

On a terrain globe every floor reread asked globe.getHeight, a ray cast against
the drawn tile's mesh, for every trail fix of every vehicle in view, twice per
pass and seven passes per poll. Over Boston's 650 vehicles that was about
150,000 reads per 10 s for about 8,000 distinct points, and blocked the page
for up to 19 s at a time while zooming.
Heights are now kept per point (1e-5 degrees), read again only while the camera
moves or tiles load, and read within a time budget: vehicle positions first,
the path a marker is drawn along next, undrawn trail history last.

A link check of every manifest found 404 licence or provider pages for
OpenSeaMap seamarks, EMODnet bathymetry and the PDOK, basemap.at, Geneva
SITG, ICGC Catalunya, Luxembourg and Vlaanderen aerial photos, and no
answer from the SEDAC GPW, Minnesota and Bangor hosts. Drop those 11
entries, renumber the unpublished share-token ledger, point the tests at
remaining entries and regenerate DATA_SOURCES.md.
An application subject's camera step is now capped at its own update
interval plus 0.1 s rather than at 0.1 s, so at 500 ms its heading slew,
ground lift and anchor correction run at their configured rates; a long
stall still moves it no further than one late update. The built-in
views keep their 0.1 s cap.
When groundClamp turns false the lift the floor gave goes at the rate
it came, not at once. A HUD view with no speed has no speed readout,
and a progress line with no summary is hidden from assistive
technology instead of being an unnamed image.
A ride let go with restore focuses its train again. When the train's
category was turned off during the ride, or for a copy another feed draws,
focusTrain selected and followed a train with no marker. It now returns
false for a train in a category turned off or hidden as another feed's
copy, and leaves the selection and the camera as they are.
The duplicate filter hid a held copy when another feed's copy outranked it
and moved the selection away, so the held train stopped playing and the
other copy's marker and card came back over the view. A copy a first-person
view holds is now drawn whatever the scores until the view lets go; the
better copy takes over at the next poll after the release. Holding a copy
that another feed drew draws it at once.
A category toggle no longer deselects a held train, and a held train keeps
playing, its marker hidden, while its category is off. Released, it is
deselected and stops as the toggle leaves any other train.
Says so where the cockpit subject section names them, together with
path.line, and that a snapshot read again while nothing changed is the one
read before, so a provider may read one on every update.
The copy keeps the path's fields with its number arrays as frozen arrays,
so pointAtS and projectOnPath read it as they read the path and nothing
written to it reaches the layer. It is built once per line and shared by
every snapshot on that line, so reading it on every frame costs nothing.
getSelectedTrain, getSelectedVehicle and getCockpitSubject fill drafts and
freeze a new object only for a part whose values changed, so a view that
reads them on every frame builds nothing while the train or vehicle stands
still, and a moving one keeps its feed, stop and provenance objects. A
train's stops are copied once per list the stops provider returns, each
stop a frozen copy, instead of on every call.
Provider methods and worded members are called on the provider itself,
so a class-based provider works. A hold that answers false refuses entry
and is released; any answer but true or false refuses it too, released,
with one warning. An answer whose `then` getter throws is handled as a
throw, and a text cut at its cap never leaves half an emoji.
The City of Amsterdam's verkeersinformatiesystemen register lists where
its ~500 traffic and ANPR cameras stand, with type and asset number, but
publishes no pictures. That fits a Data Library dataset better than a
CCTV pack: the register answers GeoJSON in WGS84 with CORS headers, so
the entry fetches it browser-direct with no proxy code.
The register names no licence ("public unless stated otherwise"), so the
entry stays operator opt-in, as #251 had it. The dataset and the
position-only camera idea come from @Maher-Reven's #251, which this
replaces; the entry lists them as maintainer and in its attribution.

DATA LAYERS keeps its curated core layers; regional and niche sources
live in the Data Library, opened from Browse data library at the foot
of the panel. Each entry is a JSON manifest in src/library/entries/
pointing at a live upstream (query API, provider-hosted file or tile
endpoint), so nothing is bundled and a self-hosted instance hosts no
data. Sources without CORS go through one allowlisted /api/library
route. Kinds: dataset (GeoJSON, CSV, JSON records, ArcGIS, partitioned
GeoParquet), tiles (XYZ, WMS/ArcGIS bbox export, terrarium relief) and
pack. Selections persist and travel in share links as lib=, separate
from the core layer tokens. Library rows get Zoom and Remove icon
chips that work while the layer is off, rendered through RailChips.
Strings are translated in every locale.
- A subject with no height at all waits at most
COCKPIT_GROUND_WAIT_TIMEOUT_MS for the floor, its HUD updating and
reading ACQUIRING SURFACE; then the view ends and the provider gets its
subject back (there is no height of its own to fall back to).
- A hold that returns a promise is refused as before and released again
once it settles, unless that subject is being ridden by then; release
must tolerate a second call.
- Rail and Transit stamp selectedAtMs only for a user's selection (a click,
focusTrain or focusVehicle); a deselection clears it, and a train or
vehicle selected only by a hold reads null.
- Labels, entry face and look may be functions, read again on every use
and on a locale change; a failing read keeps the last good value.
- A frame with no height keeps the eye's last height, or waits
(surfaceAcquiring) until the floor is known; heights outside
-1,000..50,000 m read as null.
- Provider methods are synchronous: a returned promise is refused like a
throw, and a hold that fails is released.
- A candidate may carry selectedAt; Rail and Transit stamp selectedAtMs
on every selection, so re-selecting moves a subject to the front.
- A released Transit vehicle leaves the visible set at once.
- docs/CURRENT-STATE.md states the new entry order; docs/APPLICATION.md
documents cockpit subjects, ./i18n/locale and ./layers/rail/paths.
GEV itself registers no new subject: with no provider, the Cockpit offers
aircraft, satellites and vessels as before, except that the most recently
selected of them now wins entry.
- services.cockpitSubjects: providers ({kind, layerId, entryFace, priority,
isEntryAllowed, read, hold, release, hud}) are checked once by the
coordinator; frames and HUD views on every update; a throwing provider
ends its view or keeps the last HUD.
- Entry: the most recently selected subject wins, across all kinds.
- Camera: a frame may turn the ground clamp off, anchor exactly on the
subject and update every frame.
- A generic HUD: kicker, title, cards, always-visible source rows, banner,
a veil with light streaks (off under reduced motion) and a bottom
progress line whose close ticks merge.
- Text comes from the provider, already in the page's language
(./i18n/locale: getLocale, onLocaleChange).
- Rail and Transit read and hold APIs (getSelectedTrain/Vehicle,
getCockpitSubject, setCockpitSubject, focusTrain/Vehicle); a held
train's marker, card and route line are hidden, and its feed keeps
polling while held.
- ./layers/rail/paths is exported.
Zoomed out, a hotspot's reports give way to its beacon, and the cards an application draws through pictureCards went with them; they came back only once the camera had stopped after zooming in. The cards now come from every report the close-up view would mark, at any height; the layer's own markers and beacons are unchanged.
The browser stamped every trip-updates answer as just read. While an
operator's feed fails, the rail proxy replays its last good copy for up to
ten minutes, and a cached copy can be a TTL old, so those delays never
reached RAIL_UPDATES_MAX_AGE_MS and a selected train's card showed them as
current. Delays now take their age from the snapshot's fetchedAt (capped
at now), as positions do in ingestion.js, so they stop applying 75 s after
the server last read the operator.
TaM publishes km/h where GTFS-Realtime asks m/s, and the Transit layer's
entry for the same feed already sets speedUnit: 'km/h'. The Rail entry did
not, so the proxy passed the readings through and the card multiplied them
by 3.6 again: a tram at 30 km/h read about 108 km/h. A registry test now
requires a Rail feed that Transit also reads to declare the same unit.
createNewsLayer takes a pictureCards(cards, { selectedId }) function; createApplicationCatalog passes it through newsOptions. With it, the layer paints no picture cards of its own and hands the function one card per pictured event on the map, most severe then newest first, with the selected report's id; it hands no cards when the layer turns off.
Shorter comments, changelog and CURRENT-STATE text for the 502 outage
path; the CURRENT-STATE paragraph now also names the 429 exception and
which budget expiry answers busy and which answers 502. Text only.
Core's catalog passes worldClock.timeFor('news') as the layer's now, so a host that follows the clock for News can show a past time's reports with their ages, window and counts as they were then. Core does not follow the clock for the layer, so it keeps reading the wall clock.
