📋 Decision Context

Question:

Why does clicking one checkbox in live preview select ALL rows?

Task: Fix live preview select-all checkbox bug

🎯 Decision Made

Chosen:

Normalize _id → id in BaseCrudApiService stubs (getList, getById, create, update) + fix preview bridge to not block interactive form controls

Options Considered:

Normalize _id→id in stubs API layer
Add _id fallback in useCrudList stub methods
Change generated templates to use item._id || item.id
Add backend transform in UniverseDataController

💭 Reasoning

MongoDB returns documents with _id but generated templates reference item.id. Without normalization, item.id is undefined for ALL items. toggleSelection(undefined) adds undefined to selectedIds, then isSelected(undefined) returns true for ALL rows since all pass undefined. Secondary fix: preview bridge click handler called e.preventDefault()+e.stopPropagation() on ALL clicks inside data-studio-id elements, which blocks checkboxes/buttons/links from functioning.
