Five assertions that stayed behind in core's `apiClient.test.js` when the
bindings moved in slice 1 — the atlas-vs-shard path split, the query-string
filtering, the slug encoding, the admin atlas methods — plus a new one pinning
the seven admin URLs the shipped Android app calls by name. They were asserting
UO URLs from inside core's suite, which is the boundary Phase 3 removes, and
core's slice-4 deletion of those bindings would otherwise have deleted the
coverage with them.
The fake `window.__rg` carries the REAL react/react-dom/router rather than
stubs: `src/core.js` compares its imported bindings against the published ones
and logs a "bundled its own copy" error when they differ, so stubs make every
run of this file print the exact wording of a real defect.
