a structural {kind} has been pending for over {n}s ({key}). With edit.confirm "manual" the host must call settle(id, ok); with "auto" the mutate promise never settled.

Since

1.26.0

What happened

An optimistic append or delete has been waiting beyond the timeout. The row is still shown as pending - an appended row that may never be saved, or a tombstoned row that may come back - until something settles it.

The fix

Settle the operation when your backend answers, or make sure the adapter's mutate promise always settles.
