ISOLATE · OWN · CLEAN
Keep the handle.
Lose the runtime.
Effect-exclusive mutable refs become ordinary setup-invocation closures. SDK handles, WebSockets, generation tokens, and animation frames keep familiar React-shaped source while Kudzu retains exact ownership.

EFFECT-PRIVATE OWNERSHIP
Move mutable values inward.
Keep lifecycle boundaries exact.
Create per invocation
The compiler moves exclusive refs into the inline setup closure and removes component captures.
Clean before restart
Dependency changes invalidate and clean the old closure before creating a distinct replacement.
Retain when persisted
Mount effects preserve their closure across persisted pagehide and resume through authored listeners.
Exercise real handles
E2B terminal and WebSocket fixtures verify generation, listeners, stale callbacks, and exact close behavior.
Fail closed
Cross-effect/event refs, aliases, escaped objects, nonzero initializers, and missing cleanup invalidation remain diagnosed.
UPGRADE
Let each effect own its browser resource completely.
