📝 Walkthrough

Walkthrough

This PR refactors where route match context is built and attached during navigation. Instead of using deferred commitContext calls, context is now constructed directly within state updates—during loader execution and redirect/not-found handling—resulting in fewer store updates across the routing system.

Changes

Cohort / File(s)	Summary
Core context attachment refactoring `packages/router-core/src/load-matches.ts`	Context is now built inline at state update points (success, error, redirect/notFound) via `buildMatchContext(inner, index)` rather than through separate `commitContext` calls. Removes deferred context commits from `loadRouteMatch` finalization blocks.
Test expectation updates - React Router `packages/react-router/tests/store-updates-during-navigation.test.tsx`	Adjusted expected store update counts downward across multiple navigation tests to reflect consolidated context building (e.g., 11→10, 5→4, 10→9, 8→6, 19→16).
Test expectation updates - Solid Router `packages/solid-router/tests/store-updates-during-navigation.test.tsx`	Reduced expected update counts in navigation tests (e.g., 11→10, 7→6, 10→8, 19→16, 9→7, 5→3) to align with consolidated context handling.
Test expectation updates - Vue Router `packages/vue-router/tests/store-updates-during-navigation.test.tsx`	Adjusted expected update counts downward across tests (33→27, 13→10, 31→25, 47→38, 24→18, 22→16, 18→12, 6→3) to reflect the reduced number of store updates from consolidated context building.

fix: commit route context #6053: Modifies how route context is committed/attached in load-matches.ts, moving context building to earlier stages in the flow.
fix: accumulate all parent context #6070: Directly centralizes route match context building using buildMatchContext during loader/beforeLoad flows in load-matches.ts.
getRouteApi().useRouteContext() returns undefined for beforeLoad context values in v1.140.1+ #6082: Addresses a bug where getRouteApi().useRouteContext() returns undefined for beforeLoad context values—this PR likely fixes that by ensuring context is built earlier and more consistently.

Poem

🐰 Context now blooms where updates flow,
No more deferred commits steal the show,
Consolidated paths, a cleaner way—
Fewer ripples in the store each day! ✨

Title check	✅ Passed	The title clearly describes the main fix: committing context together with status to avoid a race condition, which directly addresses the issue of undefined context values.
Linked Issues check	✅ Passed	The PR addresses issue `#6082` by fixing how context is committed with status updates in load-matches.ts, which resolves the race condition causing useRouteContext() to return undefined.
Out of Scope Changes check	✅ Passed	Test file updates in React Router, Solid Router, and Vue Router reflecting lower update counts are consistent with the core fix reducing unnecessary context commits.
