exp-shepherd found research-dashboard rendering ENDONYMS in every locale — 中国 and Türkiye on a Russian
page — and fetching a glyph range for every script on screen. The reading was that its basemap carries no
localized names and the choice was to swap the basemap or give up on its labels. Measured against the live
tiles, neither is necessary: the names are there, under keys this chain never tried.
The galaxy style is VersaTiles Colorful on the SHORTBREAD schema, whose label keys are name_ar / name_de /
name_en, not name:ar. This coalesce only tried the colon spelling, so all 43 of that style's label layers
fell through to `name` — the local name — while the localizer ran and reported success. A running fix that
cannot reach its data looks exactly like a missing feature.
MEASURED, six z3/z4 tiles across Europe, Asia and Africa, identical key sets on every one: name_ar,
name_de, name_el, name_en, name_es, name_fr, name_it, name_nl, name_pl, name_pt, name_uk. Of the eleven
locales we ship that is SEVEN in their own language — ar, de, en, es, fr, it, pt — with no change to the
basemap the Driver chose and no change to how the map looks.
hi, ro, ru and zh are genuinely absent from those tiles, so they now take name_en: one Latin script rather
than mixed CJK and Devanagari endonyms, which is also the single-script glyph saving. That is the same role
name:latin already plays for the OpenFreeMap styles, so it sits in the same position in the chain rather
than becoming a special case.
NOTHING CHANGES FOR THE OPENFREEMAP STYLES, by construction: the colon spelling stays first, so their
name:<lang> or name:latin still wins and the underscore entries are never reached. The order is also what
keeps the already-rewritten sentinel working — it tests for a chain beginning ["coalesce",["get","name:,
which this still is. Verified both, rather than assumed.
WHAT I DID NOT DO: swap the basemap. galaxy resolves to VersaTiles Colorful because the Driver asked for
blue oceans like the Mapbox map and that style's water measured closest (#bfd9f2; OpenFreeMap Liberty is
#9ebdff, noticeably stronger). Trading a look he chose for four locales' labels is his call, not mine, and
with this change those four get readable Latin labels anyway.
Verified: gates:pre 12/12. NOT measured here: glyph KB per locale, which needs a browser — rega has the
instrument and the before numbers.
