+# Phase 59.1 — Compiler diagnostic fix
+
+Fixed four error-handler expressions in the Phase 59 table search and CSV import views. Each view had a `@State` property named `error`, and the catch blocks also referenced Swift's implicit caught `error`, resulting in an ambiguous/shadowed reference while type-checking `WorkbenchTableSearchSheet.body` (reported at MainView.swift:5638). The caught exception is now explicitly bound as `caughtError`, and the UI's `error` state retains the human-readable message.
+
+This is a targeted compiler fix; no dashboard or editor UI redesign. Swift syntax parsing is verified on Linux; native macOS/Xcode compilation must be verified on a Mac.
