- submit disable trong processing
- server field error render đúng field
- recently successful feedback xuất hiện
- image preview đổi khi chọn file
- clear replacement quay lại persisted image
- filter navigation preserve input/scroll như design
- optimistic toggle rollback khi request fail

Back/Forward restores expected state
URL query sync đúng
scroll restoration
prefetched navigation vẫn đúng data
upload progress/validation flow
redirect + flash after mutation

happy path
validation reject
permission reject
entity missing/stale tab
duplicate constraint
upload failure nếu có file
server exception presentation
optimistic rollback nếu feature dùng optimistic
