+# Admin Panel UX Refactoring (2025-12-11)
+
+**Objectives:**
+- Standardize UX across Admin modules (Loading Skeletons, Alert Dialogs).
+- Fix specific display bugs in Reference Data.
+- Improve Admin Dashboard.
+
+**Achievements:**
+1.  **Dashboard Upgrade:**
+    - Replaced `/admin` redirect with a proper Dashboard page showing stats and quick links.
+    - Added `Skeleton` loading for stats.
+
+2.  **Consistency Improvements:**
+    - **Modules:** Organizations, Users, Projects, Contracts.
+    - **Changes:**
+        - Replaced "Loading..." text with `Skeleton` rows.
+        - Replaced `window.confirm()` with `AlertDialog` (Shadcn UI).
+        - Fixed `any` type violations in Users, Projects, Contracts.
+
+3.  **Reference Data Overhaul:**
+    - Refactored `GenericCrudTable` to include Skeleton loading and AlertDialogs natively.
+    - Applied to all reference pages: Correspondence Types, Disciplines, Drawing Categories, RFA Types, Tags.
+    - **Fixed Bug:** Missing "Drawing Categories" link in Reference Dashboard.
+    - **Fixed Bug:** "Drawing Categories" page displaying incorrect columns (fixed DTO matching).

+# Correspondence Module Refactoring Report
+
+**Date:** 2025-12-11
+**Objective:** Fix data display issues and align Correspondence Module with user requirements (Revision-based List).
+
+## 🛠 Fixes & Changes
+
+### 1. Revision-Based List View
+- **Issue:** The Correspondence List was displaying one row per Document, hiding revision history.
+- **Fix:** Refactored `CorrespondenceService.findAll` to query `CorrespondenceRevision` as the primary entity.
+- **Outcome:** The list now displays every revision (e.g., Doc-001 Rev A, Doc-001 Rev B) as separate rows. Added "Rev" column to the UI.
+
+### 2. Correspondence Detail Page
+- **Issue:** Detail page was not displaying Subject/Description correctly (showing "-") because it wasn't resolving the `currentRevision` correctly or receiving unwrapped data.
+- **Fix:**
+  - Updated `CorrespondenceDetail` to explicitly try finding `isCurrent` revision or fallback to index 0.
+  - Updated `useCorrespondence` (via `correspondence.service.ts`) to correctly unwrap the NestJS Interceptor response `{ data: { ... } }`.
+- **Outcome:** Detail page now correctly shows Subject, Description, and Status from the current revision.
+
+### 3. Edit Functionality
+- **Issue:** Clicking "Edit" led to a 404/Blank page.
+- **Fix:**
+  - Created `app/(dashboard)/correspondences/[id]/edit/page.tsx`.
+  - Refactored `CorrespondenceForm` to accept `initialData` and supporting "Update" mode (switching between `createMutation` and `updateMutation`).
+- **Outcome:** Users can now edit existing DRAFT correspondences.
+
+## 📂 Modified Files
