 ## 2026-07-13 - Async Table Actions UX
 **Learning:** Adding explicit loading and disabled states to table action buttons that invoke asynchronous processes helps prevent redundant API calls and visually assures the user that their request is being handled.
 **Action:** Consistently apply `disabled` state and `Loading...` text changes to inline table action buttons linked to async workflows, and carefully preserve underlying DOM structures with `Array.from(btn.childNodes)` during the loading cycle to avoid rendering regressions.

+## 2026-07-21 - Context-specific ARIA labels for repetitive table actions
+**Learning:** Screen reader users struggle to understand repetitive action buttons or links (like "Details" or "Open viewer") in a data table because the label alone lacks row context.
+**Action:** Always provide dynamically generated, context-specific `aria-label` attributes (e.g., `aria-label="Details for example_document.pdf"`) that include row-specific identifiers when rendering table action buttons or links.
