Solid 2 Pending State Issue

We are running into a Solid 2 beta issue involving isPending, latest, and a memoized optimistic store object.

https://stackblitz.com/edit/solidjs-templates-bgdbj55p?file=src%2FApp.tsx

Problematic Pattern

const user = createMemo(() => store.user);

isPending(() => latest(() => user().email));

Expected Behavior

If only store.user.name is optimistically changed, email should stay not pending.

This should behave the same as direct store access:

isPending(() => latest(() => store.user.email));

Actual Behavior

After modifying name and then calling refresh(store), email reports pending only through the memoized object path:

isPending(() => latest(() => user().email));

Direct store access does not show the false pending state:

isPending(() => latest(() => store.user.email));

Root Cause

createMemo(() => store.user) introduces an intermediate reactive source whose value is the whole user object.

During isPending(() => latest(...)), Solid collects pending sources from the read path. The memoized object source is collected in addition to the final email field.

When refresh(store) runs, the optimistic store's firewall/projection is pending. That intermediate object source sees the refresh pending state, so email incorrectly appears pending even though the email leaf was not updated.

App-Level Fix

Avoid memoizing store objects when precise field-level pending state is needed. Memoize/read the leaf property instead:

const name = createMemo(() => store.user.name);
const email = createMemo(() => store.user.email);

isPending(() => latest(name));
isPending(() => latest(email));

Or use direct store access:

isPending(() => latest(() => store.user.email));

Takeaway

Avoid memoizing store objects if you need precise field-level pending state. Memo or read the leaf property instead.

The likely framework-level bug is that isPending + latest should treat the intermediate memo object as transparent and only count the final leaf source.
