 ## 2025-06-27 - [Map Initialization Overhead]
 **Learning:** Initializing Maps with `new Map(array.map(...))` creates unnecessary intermediate arrays, consuming memory and triggering garbage collection overhead, especially noticeable when dealing with many nodes.
 **Action:** Use a `for...of` loop to directly `map.set()` elements rather than creating an intermediate array of tuples, especially in frequently executed or rendering paths.

-## 2024-07-13 - Optimize Data Dictionary Export Algorithm
-**Learning:** Found an O(N * C * E) bottleneck in `frontend/src/erd/exportDataDictionary.ts` where `isForeignKeyColumn` did an `edges.some()` search per column inside a loop over nodes and columns.
-**Action:** When writing complex export algorithms over a large graph (Nodes + Edges), always pre-compute search spaces using Maps or Sets (e.g. `fkHandles`) upfront (O(E)) to achieve O(1) lookups during deeply nested loops (O(N * C + E)).

 ## 2026-07-10 - Accessibility Anti-pattern: Excessive Tab Stops
 **Learning:** Adding `tabIndex={0}` to static, non-interactive text badges (like `abbr` or `span`) just to expose their `title` or `aria-label` attributes to keyboard users is an accessibility anti-pattern. It creates excessive tab stops and severely degrades keyboard navigation for users who rely on tab to move through actionable elements.
 **Action:** Never add `tabIndex={0}` to non-interactive elements unless they are specifically designed to be focusable for a functional reason. Use proper semantic HTML or let the screen reader read adjacent elements as part of natural navigation.
-## 2024-07-13 - Modal Close Button Unification
-**Learning:** Standardizing close buttons ('X') across disparate modal dialogs improves visual consistency and provides clear, predictable click targets, while preserving accessibility through existing `aria-label` attributes.
-**Action:** Reused the existing `exportModal__iconButton` CSS class instead of creating a new one to adhere strictly to constraints. Refrained from running global formatters to prevent out-of-scope line modifications.
+## 2024-07-12 - [Accessibility] Unique aria-labels in dynamic lists
+**Learning:** Screen readers cannot differentiate generic labels (like '컬럼명' or 'PK') when they repeat in dynamic lists or tables. Providing a static aria-label inside a mapped array causes screen readers to announce identical generic labels across different rows.
+**Action:** Always prepend or append a uniquely identifiable name (e.g., prepending the row's specific item name) to the 'aria-label' attribute of interactive elements inside dynamic lists so screen readers can correctly distinguish between them.
