📝 WalkthroughWalkthroughSolid and Vue transitioners now track expected route matches and reject stale transition acknowledgments. Regression tests cover suspended rendering, render-tick replacement, lifecycle ordering, and superseded navigations. ChangesTransition ownership acknowledgment
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The Solid and Vue adapters now reject superseded render acknowledgements, but ownership relies on match-array identity; missing or reused identities could let a stale transition report success. This is a bounded correctness risk requiring explicit owner follow-up before merge. Possibly related PRs

Both tests repeat the same teardown sequence: resolve the gate, unsubscribe every listener, then settle the pending navigation promises. A small helper would remove the duplication and keep the two tests aligned when the sequence changes.

Replace the as any cast on the Wrap option.
The repository guidelines require extensive type safety. Wrap: Wrap as any removes all checking on this option. Type the component so it satisfies the Wrap option type, or narrow the cast to the declared option type.
If the Wrap option type genuinely cannot accept a Vue component, that is a typing gap in the router options and deserves a separate fix.
As per coding guidelines: "Use TypeScript strict mode with extensive type safety".

Summary
falsewhen a newer transition takes ownership before the earlier framework flush settlesWhy
Solid.startTransitionandVue.nextTick()tell us that a framework scheduling boundary has settled, but they do not by themselves prove that the matches passed to that transition were the generation that ultimately rendered. A newer navigation can publish another expected match set before the older transition completes.Both adapters previously returned
trueunconditionally, which erased the distinction between an actual render acknowledgement and a transition replaced before commit. Tracking the latest expected match array by identity keeps that distinction accurate: the current owner acknowledges withtrue, while an older owner settles withfalse.The router core remains unchanged. Its existing transaction-currentness checks still suppress stale
onResolvedandonRenderedevents even when a generation reached the DOM before a successor navigation began.Tests
