+# JavaScript Duplication Audit Report
+
+**Generated:** 2026-02-26  
+**Scope:** static/js/**/*.js (13 files)  
+**Files Audited:** api.js, utils.js, auth.js, main.js, tabs.js, anime.js, series-search.js, downloads.js, watchlist/main.js, anime-details.js, recommendations.js, watchlist.js, watchlist-ui.js
+
+---
+
+## CRITICAL DUPLICATIONS (Potential Syntax Errors)
+
+### 1. translateStatus() Function - DUPLICATED DEFINITION
+- **File 1:** `static/js/utils.js:35` - Primary definition
+- **File 2:** `static/js/anime-details.js:428` - Duplicate definition
+
+**Impact:** HIGH - If both files are loaded, the second definition will overwrite the first, causing unpredictable behavior. The utils.js version is used by downloads.js and recommendations.js, while anime-details.js has its own localized version.
+
+**Recommendation:** Remove duplicate in anime-details.js and ensure anime-details.js imports from utils.js
+
+---
+
+## MINOR DUPLICATIONS (Non-Breaking)
+
+### 2. Redundant const Declarations in Same Function Scope (Different Functions)
+
+#### auth.js - Duplicate variable declarations across functions
+- `mainContent` declared at line 70 and line 76 (in different functions showMainContent/hideMainContent)
+- `userInfo` declared at line 57 and line 82 (in showUserInfo/showLoginPrompt)
+- `loginPrompt` declared at line 58 and line 83
+- `mainTabs` declared at line 59 and line 84
+
+**Impact:** LOW - These are in different function scopes, not causing syntax errors but creating redundant code
+
+#### recommendations.js - Duplicate variable names in different functions
+- `container` declared at lines 5, 54, 105 (in different functions)
+- `section` declared at lines 6, 55 (in different functions)
+
+**Impact:** LOW - Different function scopes
+
+#### tabs.js - Duplicate container variable
+- `container` declared at lines 115, 152, 160, 178, 186, 235, 252, 329
+
+**Impact:** LOW - Different function scopes
+
+#### anime.js - Duplicate variable names across functions
+- `selectElement` declared at lines 156, 245, 253, 261, 307, 352
+- `seasonSelectElement` declared at lines 156, 245
+- `actionsDiv` declared at lines 287, 325
+
+**Impact:** LOW - Different function scopes
+
+---
+
+## PATTERN OBSERVATIONS
+
+### Utility Functions Shared Across Files
+The following functions are defined once but used across multiple files:
+- `escapeHtml()` - Defined in utils.js:26, used in 8 files
+- `translateStatus()` - DEFINED TWICE (CRITICAL ISSUE)
+- `formatBytes()` - Defined in utils.js
+- `formatSpeed()` - Defined in utils.js
+- `extractSeriesName()` - Defined in utils.js
+- `getDayString()` - Defined in utils.js
+
+### Cross-File Function Usage
+- `renderReleaseCard()` - Defined in recommendations.js:195, called in tabs.js:171
+- `renderAnimeCard()` - Defined in anime.js:58, called in anime-details.js
+- `loadDownloads()` - Defined in downloads.js, called from multiple files
+
+---
+
+## SUMMARY
+
+| Severity | Count | Issue |
+|----------|-------|-------|
+| CRITICAL | 1 | translateStatus() defined twice (utils.js + anime-details.js) |
+| MINOR | 4+ | Redundant const declarations across functions (auth.js) |
+| MINOR | 3+ | Duplicate container/section variables (recommendations.js, tabs.js, anime.js) |
+
+---
+
+## RECOMMENDATIONS
+
+1. **FIX CRITICAL:** Remove duplicate `translateStatus()` from anime-details.js and use the version from utils.js
+2. **Consider:** Consolidating utility functions into a single utils module that all files import
+3. **Future Cleanup:** Review auth.js for redundant variable declarations (minor optimization)
+
+---
+
+## VERIFICATION
+
+Audit completed: 13 JavaScript files scanned
+Duplicate function definitions: 1 CRITICAL
+Redundant const declarations: Multiple (non-critical)
