However, `renderRouteNotFound` already accepts the un-narrowed type\nof those variables — the receiver's parameter type is broad enough that no assertion is requ\n\n**Suggested Changes (diff):**\n```diff\ndiff --git a/packages/react-router/src/Match.tsx b/packages/react-router/src/Match.tsx\nindex 1d032046..08839a78 100644\n--- a/packages/react-router/src/Match.tsx\n+++ b/packages/react-router/src/Match.tsx\n@@ -477,7 +477,7 @@ export const Outlet = React.memo(function OutletImpl() {\n ) : null\n \n if (parentGlobalNotFound) {\n- return renderRouteNotFound(router, route!, undefined)\n+ return renderRouteNotFound(router, route, undefined)\n }\n \n if (!childMatchId) {\ndiff --git a/packages/vue-router/src/Match.tsx b/packages/vue-router/src/Match.tsx\nindex 66d8d3b7..095afad1 100644\n--- a/packages/vue-router/src/Match.tsx\n+++ b/packages/vue-router/src/Match.tsx\n@@ -364,7 +364,7 @@ export const MatchInner = Vue.defineComponent({\n if (match.value!.status === 'notFound') {\n // status 'notFound' is only ever committed paired with a NotFoundError\n // (getNotFoundBoundaryPatch), so match.error needs no re-check here.\n- return renderRouteNotFound(router, route.value!, match.value!.error)\n+ return renderRouteNotFound(router, route.value, match.value!.error)\n }\n \n if (match.value!.status === 'error') {\n@@ -491,7 +491,7 @@ export const Outlet = Vue.defineComponent({\n \n return (): VNode | null => {\n if (parentGlobalNotFound.value) {\n- return renderRouteNotFound(router, route.value!, undefined)\n+ return renderRouteNotFound(router, route.value, undefined)\n }\n \n if (!childMatchData.value) {\n\n```\n\n## Actual Commit Changes\n\n**Commit Diff:**\n```diff\ndiff --git a/packages/router-core/src/load-matches.client.ts b/packages/router-core/src/load-matches.client.ts\nindex 770eb81e24..95ff6db8bf 100644\n--- a/packages/router-core/src/load-matches.client.ts\n+++ b/packages/router-core/src/load-matches.client.ts\n@@ -9,7 +9,6 @@ import {\n getMatchContext,\n getNotFoundBoundaryIndex,\n getNotFoundBoundaryPatch,\n- markError,\n normalizeRouteFailure,\n serialFailurePrefixCap,\n settleMatchLoad,\n@@ -290,18 +289,19 @@ const finalizeRouteFailure = async (\n }\n \n inner.requiresCommit = true\n- markError(inner, errorIndex)\n+ // single-call-site inline of the shared badIndex rule (byte-size)\n+ inner.badIndex = Math.min(inner.badIndex ??
