bible-posters/bible-posters is the id the Bible Posters plugin ships, so its
Experimental row is no longer provisional, and posterverse.meta.json composes
it. Lands in the SAME push as the bible-posters bundle: without it the ref is
unresolved (check:capability-derived), and with the bundle but without this
commit check:posterverse-shelf fails arm D.
With home-href but no home-label, VerticalTabsLayout falls back to labels.home,
which Posterverse did not pass, so every locale read the English default. The
shell now passes labels.home from its own strings in all 11 locales, the same
words the Research Gallery uses. A host's own home-label still wins.
poster-design/poster-design-mfe is the id poster-design-plugin ships, so its row
is no longer provisional, and posterverse.meta.json composes it. This commit
must land in the SAME push as the poster-design bundle: without the bundle the
ref is unresolved (check:capability-derived) and check:posterverse-shelf fails
arm D; with the bundle and without this commit, arm D fails the other way.
UPG Neighbor and All People Groups leave the Experimental folder: they are
research maps, and Posterverse holds the plugins whose purpose is posters.
Experimental is now Wall of People Groups (and Bible Posters once it exists).
Their labels, composes refs and heavy-tag entry go with them; the shelf gate's
allow-list and its self-test follow. The Research Gallery is unchanged.
<posterverse-app> is a vertical-tab rail of whole poster plugins, each mounted
as its real element from the manifest: UPG 100 List Posters (upg-100-mfe),
Country Posters (country-posters-mfe), Poster Design, and an Experimental
folder of Wall of People Groups, All People Groups, UPG Neighbor and Bible
Posters. It reuses VerticalTabsLayout, loadScriptOnce/whenTagDefined and the
Research Gallery's profile-config contract (urlSync:false, mapTitle, token
ladder, treeBase, assetsBase).
The whole rail is an allow-list (src/tabs.js), so a gated plugin such as
key-cities can never appear. Rows whose bundle is not in the tree are pruned;
Poster Design and Bible Posters carry provisional ids until their bundles land.
meta.json declares nested-mfe-spa and composes the five rows that exist, so
the Plugin Studio lists it under capability 5.
check:posterverse-shelf (in gates:pre) asserts the allow-list, the key-cities
exclusion, composite-not-leaf resolution, composes/rail agreement and
11-locale string parity; --self-test plants one defect per arm.
