Walkthrough

The ReactiveEffectRunner interface was removed from effect.ts, but the effect function still declares ReactiveEffectRunner as its return type. This creates an inconsistency where the return type annotation references an interface that is no longer defined.

Changes

Cohort / File(s)	Summary
Type removal packages/reactivity/src/effect.ts	Deleted exported interface ReactiveEffectRunner<T = any> with callable signature () => T and effect: ReactiveEffect member. The effect() function return type annotation still references the now-undefined ReactiveEffectRunner<T> type.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Critical attention point: Verify whether the effect() function's return type annotation should also be removed or updated, as it now references an undefined interface, creating a public API inconsistency.
• Confirm this is an intentional breaking change and not an incomplete refactoring.
• Check that all internal and external usages of ReactiveEffectRunner have been addressed.

Poem

🐰 A runner once stood tall and proud,
With types and effects worn loud,
But now it's gone—no trace remains,
Leaving function signatures with orphaned chains,
Did we mean to break this dance so free?
