Embedded with profile-config {"locale":"ar"}, these dashboards came back half
translated: the map's six tabs in Arabic and the grid's four dropdown labels in
English, on the same screen. That reads as "some strings were never translated",
and it sends whoever investigates to the catalogues — where every one of those
strings is already present and correct.
Two readers, one locale, and only one of them was being told.
t() — vue-i18n, follows the plugin's locale, which ProfileLoader already
drove from the host's config.
tStatic — the plugin-free reader that components mounted as their own custom
element must use (useI18n() throws at a custom-element root and
takes the subtree with it). It resolved the locale from the URL and
the document, which are the only two things a STATIC page can say.
So a locale set at RUNTIME moved every t() string and no tStatic string. Now the
i18n instance publishes its locale whenever it changes — one choke point, so
ProfileLoader, the SPA's picker and the studio's picker all work without any of
them remembering to tell the static reader as well.
★ ON THE WINDOW, NOT IN THIS MODULE, AND THE FIRST VERSION GOT THIS WRONG.
A composite loads SEVERAL bundles — research-map-plus-grid loads its own,
doxa-research-map's and people-groups-grid's — and each carries its own copy of
library/i18n. A module-level variable set inside the map's copy is invisible to
the grid's copy, so the first attempt translated the map and left the grid in
English: the very defect it was written to remove, reproduced one layer down.
Measured, then moved to a window-level store, the way the shared map token has
always crossed bundles. Module state is per-BUNDLE; a locale is per-PAGE.
Both composites also publish the locale themselves, because a composite sits
ABOVE every ProfileLoader on its page rather than under one.
MEASURED with check:host-locale-contract, on c7c2050d and on this commit:
dashboard-plus-grid/dashboard-plus-grid 32 of 2121 -> 2121 of 2121
research-dashboard/research-dashboard 75 of 1891 -> 1891 of 1891
research-map-plus-grid 489 of 1201 -> 1201 of 1201
whole fleet 18 failing -> 1 failing
The one left is big-picture/big-picture, which installs no i18n and mounts no
ProfileLoader at all — a different shape of gap, and not this lane's bundle.
Every bundle was rebuilt; composite-freshness and SRI are clean.
