Keep errors hidden until the row is touched.
Formik validates on change by default, and validate returns errors for every invalid non-trailing row. rowError reads each field error directly, so changing or blurring one row can display errors for untouched rows. Gate the error on the row's nameMeta.touched state.
Proposed fix
- const rowError = isLastEmptyRow
+ const nameMeta = formik.getFieldMeta(`${actualIndex}.name`);
+ const rowError = isLastEmptyRow || !nameMeta.touched
? null

Use collectionUid for collection locator identity.
CreateCollection validates collectionName for length but does not require slug uniqueness. Distinct collections such as A B and a-b can therefore exist in one workspace. flattenSidebarTree.js sets data-collection-id from collectionSlug(collection.name), while SidebarRow also exposes the unique data-collection-uid.
The locator helpers and callers still query data-collection-id by name. They can match rows from both collections and operate on the wrong collection. Update them to use the existing UID-based locator. Keep collectionSlug only for readable metadata.

Preserve the parent UID in flattened rows.
parentName is not a unique ancestry key. Two folders or requests can have the same display name in different branches or collections.
The new data-parent-name consumers in tests/utils/page/actions.ts, tests/utils/page/runner.ts, and tests/utils/page/sidebar/index.ts can therefore select and operate on the wrong branch.
Add parentUid to these rows. Scope descendant locators by collection UID and parent UID.

Do not treat mounted Virtuoso rows as the complete collection.
allRows(collectionName) returns only rows currently mounted in the viewport. expandAllFolders also sees only mounted folder chevrons.
For a collection larger than the viewport, these helpers can omit offscreen rows, stop before expanding all folders, return an incomplete tree, or time out while waiting for the total item count.
Scroll through the virtual list while expanding and collecting rows, or read the complete flattened model through a test-facing application API.
