@tanstack/router-core@1.171.28

### Patch Changes

-   [#8222](https://github.com/TanStack/router/pull/8222) [`edf0e16`](https://github.com/TanStack/router/commit/edf0e16ebfe82ec6e8f68f403a1fda8de9e28889) - Make each load transaction's completion follow its current successor so a burst of back-to-back loads wakes each superseded waiter once instead of once per successor. Previously every superseded `load()` re-polled the current transaction on each later completion, which was quadratic in microtask work.

-   [#8165](https://github.com/TanStack/router/pull/8165) [`2f20c00`](https://github.com/TanStack/router/commit/2f20c00224c5ba63467551914e0c37012588c4c2) - Exclude structural descendants below error and not-found boundaries from route lifecycle callbacks. Preserve lifecycle membership through invalidation, hydration, background reloads, and superseded navigation publication.

-   [#8209](https://github.com/TanStack/router/pull/8209) [`28a5e45`](https://github.com/TanStack/router/commit/28a5e4504e4ea5cb1480667a4bea2588a53e110f) - Preserve falsy thrown values in React and Vue error boundaries. Type React and Vue boundary error components and `onCatch` callbacks as `unknown`. Solid boundary errors remain typed as `Error`; SSR now wraps non-`Error` loader errors to match Solid’s native boundary behavior, preserving the original value in `cause`. Router state and loader `onError` values are unchanged.

    When upgrading React or Vue, narrow boundary errors (for example, with `error instanceof Error`) before reading `message` or `stack`. `ErrorComponentProps<TError>` remains available for values narrowed to a specific error type. Route `onError` types are unchanged.

-   [#8207](https://github.com/TanStack/router/pull/8207) [`08eff50`](https://github.com/TanStack/router/commit/08eff50c447a154a3373909009e9e4375cea17ce) - Fix consumer typechecking with `skipLibCheck: false` by omitting the internal beforeLoad context field from published dehydrated match declarations.

    Retain the exported `isAbsoluteUrl` declaration used by framework bindings so the package entry point does not reference a stripped symbol.

-   [#8259](https://github.com/TanStack/router/pull/8259) [`216c0c4`](https://github.com/TanStack/router/commit/216c0c48036fd1a33163b70dcabfed2b893808b0) - Reduce Promise allocations during client navigation and static server SSR policy resolution. Skip cancellable waits for synchronous beforeLoad results while preserving navigation cancellation.

-   [#8240](https://github.com/TanStack/router/pull/8240) [`2f91503`](https://github.com/TanStack/router/commit/2f9150309bc472f4a75cbe98adcdb50c76b12c7a) - Avoid quadratic resource handoff scans when navigating with many cached route matches.

-   [#8161](https://github.com/TanStack/router/pull/8161) [`f0b5eda`](https://github.com/TanStack/router/commit/f0b5eda544606686a8a8d675a686ca1366428b96) - Retain successful not-found matches as terminal shared boundaries during client navigation, preserving route context while the destination loads.

-   [#8142](https://github.com/TanStack/router/pull/8142) [`50eafca`](https://github.com/TanStack/router/commit/50eafcaebbbedb6fde3b2816de7a0ace8cde4832) - Avoid unnecessary JSON.parse calls for search parameter values that cannot begin valid JSON, while preserving custom parser behavior.

-   [#8251](https://github.com/TanStack/router/pull/8251) [`0497cae`](https://github.com/TanStack/router/commit/0497caeef3ff7e1c1c6080eca38bca24e7ec320b) - Use URL.canParse for absolute URL checks in links, navigation, redirects, and build configuration. Preserve a URL constructor fallback for older browsers.

-   [#8230](https://github.com/TanStack/router/pull/8230) [`ee28348`](https://github.com/TanStack/router/commit/ee283480dfa51150a2e0b096a6eff94a89ff8b3f) - Replace the internal LRU cache behind path resolution, route matching and the SSR manifest lookup with a smaller SIEVE cache whose hits no longer relink a list, and fix an eviction edge case in the old implementation.

-   [#8244](https://github.com/TanStack/router/pull/8244) [`c18e690`](https://github.com/TanStack/router/commit/c18e69081475a7c98f9d40bd0fe6da78ccb84598) - Reduce promise allocations during client navigation when loader data and route components are already available.
