THE GROUP WAS SCHEDULED AS ONE LANDING AND DELIVERED AS TWO. Section 8 of the spec puts the facet
rail, the chip bar and the BREADCRUMB in a single landing. The rail moved in 4c-3 and the chips in
4c-2; the breadcrumb was left behind, and nothing failed, because it is mounted by nobody. A leftover
like that is invisible unless someone re-reads the spec against the tree, which is what this landing
came out of.
The breadcrumb gets exactly the inversion the chip bar got: no useTreeLegendLabels import, the
resolver read from dashboardConfig.legend, and the SAME unconfigured default — identity, joining an
array. Identical on purpose rather than by copy-paste: the breadcrumb and the chips render the same
filterSet in the same band, so if their defaults differed a half-configured dashboard would show one
value resolved and the other raw, side by side. Its dead `dataStore` / `searchSourceId` injects go
too; they existed only to build the composable that is no longer imported.
★ AND THREE ONE-CYCLE SHIMS FROM LANDINGS 2 AND 3 WERE NEVER RETIRED. plugin-designs/research-
dashboard/src/composables/ still held useDashboardLayout.js (11 lines), useSelectionCamera.js (11) and
useCsvExport.js (14), each a pure re-export of the library module. MEASURED before deleting: ZERO
importers. Every consumer — including DashboardMapPanel, DashboardDataTable, DashboardDetailDrawer,
useDashboardShell, gospel-internet's board and research-dashboard.vue — already reads
'@map/composables/…' directly, and a tree-wide grep for a relative import of any of the three returns
nothing. So they were dead code that made the plugin look like it still owned three library modules.
I wrote "a one-cycle shim that nobody retires is permanent" into the previous landing's gate comment
while three older ones were sitting in the tree unnoticed. They were not found by a gate; they were
found by listing what is still in plugin-designs and comparing it against the spec.
check:legend-mirrors arm 5 now guards three moved names instead of two, so a re-export of the
breadcrumb creeping back into the plugin barrel is caught the same way.
Source only. research-dashboard and dashboard-plus-grid need a rebuild.
