The Global Context range ring was a Cesium ellipse outline at 1 px in
rgba(98,181,255,0.72). WebGL ignores larger ellipse outline widths, so it
could not be thickened, and it vanished over desert and snow and under the
FLIR, NVG and CRT styles.
Draw it as a polyline instead: a 4 px line with a 2 px Context-blue core
inside a 1 px dark halo on each side (PolylineOutlineMaterialProperty).
The halo gives luminance contrast on light and dark ground, which the
monochrome styles keep. The ring sits at the same 2.5 km height and
follows the subject on the same 250 m threshold. Positions come from a
new awarenessRangeRingPositions helper that stays within 50 m of 250 km.
Style values live in AWARENESS_RANGE_RING_STYLE (awareness/policy.js).
Adds rangeRing.test.mjs (geometry at equator, Sahara, Greenland and the
antimeridian; contrast; entity shape; follow threshold) and a
CURRENT-STATE note.
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.
- strip control and format characters from OSM tag values, keeping the
zero-width (non-)joiners Persian and Indic names spell with, and cut
them at 120 code points so a name cannot steer or flood the model
- adopt the nine new geometry test files in format-scope.json; five of
them change by formatting only
Both stack parents (#837, #842) are on main, so the voice geometry branch
now builds on main directly. Conflict resolutions keep main's behaviour and
add the geometry work on top: osm_query gating on every provider, restored
admin identity for Nominatim outlines, merged analyst follow-up memory, and
the cancelled Globe View reset instruction ahead of the generic cancellation.
Resolve the CURRENT-STATE.md layer table by keeping main's realigned
table and adding this layer's row. Main added an Arabic locale, so
translate the 12 layer strings and list ar.json in the drone-airspace
package.
