+# Port: fix(inertia): make `useRoute().fullPath` reactive across navigations (#6696)
+
+**Upstream:** `c256997f33b44324d43b212bae6b2be2de83b42c` (nuxt/ui)
+**Decision:** port
+
+## Upstream change
+The Inertia `useRoute()` stub returned `fullPath: page.url` — a value captured
+once at call time, so it went stale across Inertia navigations. Change it to a
+getter (`get fullPath() { return page.url }`) so reads always reflect the
+current `page.url`.
+
+## b24ui port — direct 1:1
+b24ui's stub lives at `src/runtime/vue/stubs/inertia.ts` and matched upstream
+(`usePage()` + `return { fullPath: page.url }`). Converted the property to a
+getter verbatim. No renames.
+
+## Tests
+Runtime stub, no markup change → no snapshot churn. Full suite unchanged (5289
+passed / 6 skipped).
+
+## Verify (CI=true)
+`dev:prepare` · `lint` · `typecheck` · `test` · `build` — all green.
