-# Security Dashboard Live Logs - Complete Trace Analysis
+# Charon UI/UX Improvement Plan
 
+**Issue:** GitHub #409 - UI Enhancement & Design System
 **Date:** December 16, 2025
-**Status:** ✅ ALL ISSUES FIXED & VERIFIED
-**Severity:** Was Critical (WebSocket reconnection loop) → Now Resolved
+**Status:** ✅ Completed
+**Completion Date:** December 16, 2025
+**Stack:** React 19 + Vite + TypeScript + TanStack Query + Tailwind CSS v4

-## 0. FULL TRACE ANALYSIS
+## Executive Summary
 
-### File-by-File Data Flow
+The current Charon UI is functional but lacks design consistency, visual polish, and systematic component architecture. This plan addresses Issue #409's recommendations to transform the interface from "bland" to professional-grade through:
 
-| Step | File | Lines | Purpose | Status |
-|------|------|-------|---------|--------|
-| 1 | `frontend/src/pages/Security.tsx` | 36, 421 | Renders LiveLogViewer with memoized filters | ✅ Fixed |
-| 2 | `frontend/src/components/LiveLogViewer.tsx` | 138-143, 183-268 | Manages WebSocket lifecycle in useEffect | ✅ Fixed |
-| 3 | `frontend/src/api/logs.ts` | 177-237 | `connectSecurityLogs()` - builds WS URL with auth | ✅ Working |
-| 4 | `backend/internal/api/routes/routes.go` | 373-394 | Registers `/cerberus/logs/ws` in protected group | ✅ Working |
-| 5 | `backend/internal/api/middleware/auth.go` | 12-39 | Validates JWT from header/cookie/query param | ✅ Working |
-| 6 | `backend/internal/api/handlers/cerberus_logs_ws.go` | 27-120 | WebSocket handler with filter parsing | ✅ Working |
-| 7 | `backend/internal/services/log_watcher.go` | 44-237 | Tails Caddy access log, broadcasts to subscribers | ✅ Working |
+1. **Design Token System** - Consistent colors, spacing, typography
+2. **Component Library** - Reusable, accessible UI primitives
+3. **Layout Improvements** - Better dashboards, tables, empty states
+4. **Page Polish** - Systematic improvement of all pages

+## 1. Current State Analysis
+
+### 1.1 Tailwind Configuration (tailwind.config.js)
+
+**Current:**
+```javascript
+colors: {
+  'light-bg': '#f0f4f8',
+  'dark-bg': '#0f172a',
+  'dark-sidebar': '#020617',
+  'dark-card': '#1e293b',
+  'blue-active': '#1d4ed8',
+  'blue-hover': '#2563eb',
+}
 ```
 
-### Logic Gap Analysis
+**Problems:**
+- ❌ Only 6 ad-hoc color tokens
+- ❌ No semantic naming (surface, border, text layers)
+- ❌ No state colors (success, warning, error, info)
+- ❌ No brand color scale
+- ❌ No spacing scale beyond Tailwind defaults
+- ❌ No typography configuration
 
-**ANSWER: NO - There is NO logic gap between Frontend and Backend.**
+### 1.2 CSS Variables (index.css)
 
-| Question | Answer |
-|----------|--------|
-| Frontend auth method | Query param `?token=<jwt>` from `localStorage.getItem('charon_auth_token')` |
-| Backend auth method | Accepts: Header → Cookie → Query param `token` ✅ |
-| Filter params | Both use `source`, `level`, `ip`, `host`, `blocked_only` ✅ |
-| Data format | `SecurityLogEntry` struct matches frontend TypeScript type ✅ |
-
----
-
-## 1. VERIFICATION STATUS
-
-### ✅ localStorage Key IS Correct
-
-Both WebSocket functions in `frontend/src/api/logs.ts` correctly use `charon_auth_token`:
-
-- **Line 119-122** (`connectLiveLogs`): `localStorage.getItem('charon_auth_token')`
-- **Line 178-181** (`connectSecurityLogs`): `localStorage.getItem('charon_auth_token')`
-
----
-
-## 2. ALL ISSUES FOUND (NOW FIXED)
-
-### Issue #1: CRITICAL - Object Reference Instability in Props (ROOT CAUSE) ✅ FIXED
-
-**Problem:** `Security.tsx` passed `securityFilters={{}}` inline, creating a new object on every render. This triggered useEffect cleanup/reconnection on every parent re-render.
-
-**Fix Applied:**
-
-```tsx
-// frontend/src/pages/Security.tsx line 36
-const emptySecurityFilters = useMemo(() => ({}), [])
-
-// frontend/src/pages/Security.tsx line 421
-<LiveLogViewer mode="security" securityFilters={emptySecurityFilters} className="w-full" />
+**Current:**
+```css
+:root {
+  font-family: Inter, system-ui, Avenir, Helvetica, Arial, sans-serif;
+  color: rgba(255, 255, 255, 0.87);
+  background-color: #0f172a;
+}
 ```
 
-### Issue #2: Default Props Had Same Problem ✅ FIXED
+**Problems:**
+- ❌ Hardcoded colors, not CSS variables
+- ❌ No dark/light mode toggle system
+- ❌ No type scale
+- ❌ Custom animations exist but no transition standards
 
-**Problem:** Default empty objects `filters = {}` in function params created new objects on each call.
+### 1.3 Existing Component Library (frontend/src/components/ui/)
 
-**Fix Applied:**
+| Component | Status | Issues |
+|-----------|--------|--------|
+| `Button.tsx` | ✅ Good foundation | Missing outline variant, icon support |
+| `Card.tsx` | ✅ Good foundation | Missing hover states, compact variant |
+| `Input.tsx` | ✅ Good foundation | No textarea, select variants |
+| `Switch.tsx` | ⚠️ Functional | Hard-coded colors, no size variants |
 
-```typescript
-// frontend/src/components/LiveLogViewer.tsx lines 138-143
-const EMPTY_LIVE_FILTER: LiveLogFilter = {};
-const EMPTY_SECURITY_FILTER: SecurityLogFilter = {};
+**Missing Components:**
+- Badge/Tag
+- Alert/Callout
+- Dialog/Modal (exists ad-hoc in pages)
+- Dropdown/Select
+- Tabs
+- Tooltip
+- Table (data table with sorting)
+- Skeleton loaders
+- Progress indicators
 
-export function LiveLogViewer({
-  filters = EMPTY_LIVE_FILTER,
-  securityFilters = EMPTY_SECURITY_FILTER,
-  // ...
-})
-```
+### 1.4 Page-Level UI Patterns
 
-### Issue #3: `showBlockedOnly` Toggle (INTENTIONAL)
+| Page | Patterns | Issues |
+|------|----------|--------|
+| Dashboard | KPI cards, links | Cards lack visual hierarchy, no trend indicators |
+| ProxyHosts | Data table, modals | Inline modals, inconsistent styling, no sticky headers |
+| Security | Layer cards, toggles | Good theming, but cards cramped |
+| Settings | Tab navigation, forms | Basic tabs, form styling inconsistent |
+| AccessLists | Table with selection | Good patterns, inline confirm dialogs |
 
-The `showBlockedOnly` state in useEffect dependencies causes reconnection when toggled. This is **intentional** for server-side filtering - not a bug.
+### 1.5 Inconsistencies Found
+
+1. **Modal Patterns**: Some use `fixed inset-0`, some use custom positioning
+2. **Button Styling**: Mix of `bg-blue-active` and `bg-blue-600`
+3. **Card Borders**: Some use `border-gray-800`, others `border-gray-700`
+4. **Text Colors**: Inconsistent use of gray scale (gray-400/500 for secondary)
+5. **Spacing**: No consistent page gutters or section spacing
+6. **Focus States**: `focus:ring-2` used but not consistently
+7. **Loading States**: Custom Charon/Cerberus loaders exist but not used everywhere

-## 3. ROOT CAUSE ANALYSIS
+## 2. Design Token System
 
-### The Reconnection Loop (Before Fix)
+### 2.1 CSS Variables (index.css)
 
-1. User navigates to Security Dashboard
-2. `Security.tsx` renders with `<LiveLogViewer securityFilters={{}} />`
-3. `LiveLogViewer` mounts → useEffect runs → WebSocket connects
-4. React Query refetches security status
-5. `Security.tsx` re-renders → **new `{}` object created**
-6. `LiveLogViewer` re-renders → useEffect sees "changed" `securityFilters`
-7. useEffect cleanup runs → **WebSocket closes**
-8. useEffect body runs → **WebSocket opens**
-9. Repeat steps 4-8 every ~100ms

-## 5. SUMMARY TABLE
-
-| Component | Status | Notes |
-|-----------|--------|-------|
-| localStorage key | ✅ Fixed | Now uses `charon_auth_token` |
-| Auth middleware | ✅ Working | Accepts query param `token` |
-| WebSocket endpoint | ✅ Working | Protected route, upgrades correctly |
-| LogWatcher service | ✅ Working | Tails access.log successfully |
-| **Frontend memoization** | ✅ Fixed | `useMemo` in Security.tsx |
-| **Stable default props** | ✅ Fixed | Constants in LiveLogViewer.tsx |
-
----
-
-## 6. VERIFICATION STEPS
-
-After any changes, verify with:
-
-```bash
-# 1. Rebuild and restart
-docker build -t charon:local . && docker compose -f docker-compose.override.yml up -d
-
-# 2. Check for stable connection (should see ONE connect, no rapid cycling)
-docker logs charon 2>&1 | grep -i "cerberus.*websocket" | tail -10
-
-# 3. Browser DevTools → Console
-# Should see: "Cerberus logs WebSocket connection established"
-# Should NOT see repeated connection attempts
-```
-
----
-
-## 7. CONCLUSION
-
-**Root Cause:** React reference instability (`{}` creates new object on every render)
-

-# Health Check 401 Auth Failures - Investigation Report
-
-**Date:** December 16, 2025
-**Status:** ✅ ANALYZED - NOT A BUG
-**Severity:** Informational (Log Noise)
-
----
-
-## 1. INVESTIGATION SUMMARY
-
-### What the User Observed
-
-The user reported recurring 401 auth failures in Docker logs:
-```
-01:03:10 AUTH 172.20.0.1 GET / → 401 [401] 133.6ms
-{ "auth_failure": true }
-01:04:10 AUTH 172.20.0.1 GET / → 401 [401] 112.9ms
-{ "auth_failure": true }
-```
-
-### Initial Hypothesis vs Reality
-
-| Hypothesis | Reality |
-|------------|---------|
-| Docker health check hitting `/` | ❌ Docker health check hits `/api/v1/health` and works correctly (200) |
-| Charon backend auth issue | ❌ Charon backend auth is working fine |
-| Missing health endpoint | ❌ `/api/v1/health` exists and is public |
-
----
-
-## 2. ROOT CAUSE IDENTIFIED
-
-### The 401s are FROM Plex, NOT Charon
-
-**Evidence from logs:**
-
-```json
-{
-  "host": "plex.hatfieldhosted.com",
-  "uri": "/",
-  "status": 401,
-  "resp_headers": {
-    "X-Plex-Protocol": ["1.0"],
-    "X-Plex-Content-Compressed-Length": ["157"],
-    "Cache-Control": ["no-cache"]
+    /* States - Muted versions for dark mode */
+    --color-success-muted: 20 83 45;     /* green-900 */
+    --color-warning-muted: 113 63 18;    /* yellow-900 */
+    --color-error-muted: 127 29 29;      /* red-900 */
+    --color-info-muted: 30 58 138;       /* blue-900 */
   }
 }
 ```
 
-The 401 responses contain **Plex-specific headers** (`X-Plex-Protocol`, `X-Plex-Content-Compressed-Length`). This proves:
+### 2.2 Tailwind Configuration (tailwind.config.js)
 
-1. The request goes through Caddy to **Plex backend**
-2. **Plex** returns 401 because the request has no auth token
-3. Caddy logs this as a handled request
-
-### What's Making These Requests?
-
-**Charon's Uptime Monitoring Service** (`backend/internal/services/uptime_service.go`)
-
-The `checkMonitor()` function performs HTTP GET requests to proxied hosts:
-
-```go
-case "http", "https":
-    client := http.Client{Timeout: 10 * time.Second}
-    resp, err := client.Get(monitor.URL)  // e.g., https://plex.hatfieldhosted.com/
-```
-
-Key behaviors:
-- Runs every 60 seconds (`interval: 60`)
-- Checks the **public URL** of each proxy host
-- Uses `Go-http-client/2.0` User-Agent (visible in logs)
-- **Correctly treats 401/403 as "service is up"** (lines 471-474 of uptime_service.go)

-## 5. WHY THIS IS NOT A BUG
+## 5. Implementation Phases
 
-### Uptime Service Design is Correct
+### Phase 1: Design Tokens Foundation (Week 1)
 
-From [uptime_service.go#L471-L474](backend/internal/services/uptime_service.go#L471-L474):
+**Files to Modify:**
+- [frontend/src/index.css](frontend/src/index.css) - Add CSS variables
+- [frontend/tailwind.config.js](frontend/tailwind.config.js) - Add semantic color mapping
 
-```go
-// Accept 2xx, 3xx, and 401/403 (Unauthorized/Forbidden often means the service is up but protected)
-if (resp.StatusCode >= 200 && resp.StatusCode < 400) || resp.StatusCode == 401 || resp.StatusCode == 403 {
-    success = true
-    msg = fmt.Sprintf("HTTP %d", resp.StatusCode)
-}
-```
+**Files to Create:**
+- None (modify existing)
 
-**Rationale:** A 401 response proves:
-- The service is running
-- The network path is functional
-- The application is responding
+**Tasks:**
+1. Add CSS custom properties to `:root` and `.dark` in index.css
+2. Update tailwind.config.js with new color tokens
+3. Test light/dark mode switching
+4. Verify no visual regressions
 
-This is industry-standard practice for uptime monitoring of auth-protected services.
+**Testing:**
+- Visual regression test for Dashboard, Security, ProxyHosts
+- Dark/light mode toggle verification
+- Build succeeds without errors
 
 ---
 
-## 6. RECOMMENDATIONS
+### Phase 2: Core Component Library (Weeks 2-3)
 
-### Option A: Do Nothing (Recommended)
+**Files to Create:**
+- [frontend/src/components/ui/Badge.tsx](frontend/src/components/ui/Badge.tsx)
+- [frontend/src/components/ui/Alert.tsx](frontend/src/components/ui/Alert.tsx)
+- [frontend/src/components/ui/Dialog.tsx](frontend/src/components/ui/Dialog.tsx)
+- [frontend/src/components/ui/Select.tsx](frontend/src/components/ui/Select.tsx)
+- [frontend/src/components/ui/Tabs.tsx](frontend/src/components/ui/Tabs.tsx)
+- [frontend/src/components/ui/Tooltip.tsx](frontend/src/components/ui/Tooltip.tsx)
+- [frontend/src/components/ui/Skeleton.tsx](frontend/src/components/ui/Skeleton.tsx)
+- [frontend/src/components/ui/Progress.tsx](frontend/src/components/ui/Progress.tsx)
+- [frontend/src/components/ui/Checkbox.tsx](frontend/src/components/ui/Checkbox.tsx)
+- [frontend/src/components/ui/Label.tsx](frontend/src/components/ui/Label.tsx)
+- [frontend/src/components/ui/Textarea.tsx](frontend/src/components/ui/Textarea.tsx)
+- [frontend/src/components/ui/index.ts](frontend/src/components/ui/index.ts) - Barrel exports
 
-The current behavior is correct:
-- Docker health checks work ✅
-- Uptime monitoring works ✅
-- Plex is correctly marked as "up" despite 401 ✅
+**Files to Modify:**
+- [frontend/src/components/ui/Button.tsx](frontend/src/components/ui/Button.tsx) - Enhance with variants
+- [frontend/src/components/ui/Card.tsx](frontend/src/components/ui/Card.tsx) - Add hover, variants
+- [frontend/src/components/ui/Input.tsx](frontend/src/components/ui/Input.tsx) - Enhance styling
+- [frontend/src/components/ui/Switch.tsx](frontend/src/components/ui/Switch.tsx) - Use tokens
 
-The 401s in Caddy access logs are informational noise, not errors.
+**Dependencies to Add:**
+```bash
+npm install class-variance-authority @radix-ui/react-dialog @radix-ui/react-tooltip @radix-ui/react-tabs @radix-ui/react-select @radix-ui/react-checkbox @radix-ui/react-progress
+```
 
-### Option B: Reduce Log Verbosity (Optional)
+**Testing:**
+- Unit tests for each new component
+- Storybook-style visual verification (manual)
+- Accessibility audit (keyboard nav, screen reader)
 
-If the log noise is undesirable, options include:
+---
 
-1. **Configure Caddy to not log uptime checks:**
-   Add a log filter for `Go-http-client` User-Agent
+### Phase 3: Layout Components (Week 4)
 
-2. **Use backend health endpoints:**
-   Some services like Plex have health endpoints (`/identity`, `/status`) that don't require auth
+**Files to Create:**
+- [frontend/src/components/layout/PageShell.tsx](frontend/src/components/layout/PageShell.tsx)
+- [frontend/src/components/ui/StatsCard.tsx](frontend/src/components/ui/StatsCard.tsx)
+- [frontend/src/components/ui/EmptyState.tsx](frontend/src/components/ui/EmptyState.tsx) (enhance existing)
+- [frontend/src/components/ui/DataTable.tsx](frontend/src/components/ui/DataTable.tsx)
 
-3. **Add per-monitor health path option:**
-   Extend `UptimeMonitor` model to allow custom health check paths
+**Files to Modify:**
+- [frontend/src/components/Layout.tsx](frontend/src/components/Layout.tsx) - Apply token system
 
-### Option C: Already Implemented
+**Testing:**
+- Responsive layout tests
+- Mobile sidebar behavior
+- Table scrolling with sticky headers
 
-The Uptime Service already logs status changes only, not every check:
+---
 
-```go
-if statusChanged {
-    logger.Log().WithFields(map[string]interface{}{
-        "host_name": host.Name,
-        // ...

+
+## 7. Testing Requirements
+
+### Unit Tests
+Each new component needs:
+- Render test (renders without crashing)
+- Variant tests (all variants render correctly)
+- Interaction tests (onClick, onChange work)
+- Accessibility tests (aria labels, keyboard nav)
+
+### Integration Tests
+- Dark/light mode toggle persists
+- Page navigation maintains theme
+- Forms submit correctly with new components
+- Modals open/close properly
+
+### Visual Regression
+- Screenshot comparison for:
+  - Dashboard (light + dark)
+  - ProxyHosts table (empty + populated)
+  - Security dashboard (enabled + disabled)
+  - Settings tabs
+
+### Accessibility
+- WCAG 2.1 AA compliance
+- Keyboard navigation throughout
+- Focus visible on all interactive elements
+- Screen reader compatibility
+
+---
+
+## 8. Migration Strategy
+
+### Backward Compatibility
+1. Keep legacy color tokens (`dark-bg`, `dark-card`, etc.) during transition
+2. Gradually replace hardcoded colors with semantic tokens
+3. Use `cn()` utility for all className merging
+4. Create new components alongside existing, migrate pages incrementally
+
+### Rollout Order
+1. **Token system** - No visual change, foundation only
+2. **New components** - Available but not used
+3. **Dashboard** - High visibility, validates approach
+4. **ProxyHosts** - Most complex, proves scalability
+5. **Remaining pages** - Systematic cleanup
+
+### Deprecation Path
+After all pages migrated:
+1. Remove legacy color tokens from tailwind.config.js
+2. Remove inline modal patterns
+3. Remove ad-hoc button styling
+4. Clean up unused CSS
+
+---
+
+## 9. Success Metrics
+
+| Metric | Current | Target |
+|--------|---------|--------|
+| Unique color values in CSS | 50+ hardcoded | <20 via tokens |
+| Component reuse | ~20% | >80% |
+| Inline styles | Prevalent | Eliminated |
+| Accessibility score (Lighthouse) | Unknown | 90+ |
+| Dark/light mode support | Partial | Complete |
+| Loading states coverage | ~30% | 100% |
+| Empty states coverage | ~50% | 100% |
+
+---
+
+## 10. Open Questions / Decisions Needed
+
+1. **Font loading strategy**: Should we self-host Inter/JetBrains Mono or use CDN?
+2. **Animation library**: Use Framer Motion for complex animations or keep CSS-only?
+3. **Form library integration**: Deeper react-hook-form integration with new Input components?
+4. **Icon library**: Stick with lucide-react or consider alternatives?
+5. **Radix UI scope**: All primitives or selective use for accessibility-critical components?

-## 7. SUMMARY TABLE
-
-| Question | Answer |
-|----------|--------|
-| What is making the requests? | Charon's Uptime Service (`Go-http-client/2.0`) |
-| Should `/` be accessible without auth? | N/A - this is hitting proxied backends, not Charon |
-| Is there a dedicated health endpoint? | Yes: `/api/v1/health` (public, returns 200) |
-| Is Docker health check working? | ✅ Yes, every 30s, returns 200 |
-| Are the 401s a bug? | ❌ No, they're expected from auth-protected backends |
-| What's the fix? | None needed - working as designed |
-
----
-
-## 8. CONCLUSION
-
-**The 401s are NOT from Docker health checks or Charon auth failures.**
-
-They are normal responses from **auth-protected backend services** (like Plex) being monitored by Charon's uptime service. The uptime service correctly interprets 401/403 as "service is up but requires authentication."
-
-**No fix required.** The system is working as designed.

+                                      Upgrade to WebSocket
+```
+
+### Logic Gap Analysis
+
+**ANSWER: NO - There is NO logic gap between Frontend and Backend.**
+
+| Question | Answer |
+|----------|--------|
+| Frontend auth method | Query param `?token=<jwt>` from `localStorage.getItem('charon_auth_token')` |
+| Backend auth method | Accepts: Header → Cookie → Query param `token` ✅ |
+| Filter params | Both use `source`, `level`, `ip`, `host`, `blocked_only` ✅ |
+| Data format | `SecurityLogEntry` struct matches frontend TypeScript type ✅ |
+
+---
+
+## 1. VERIFICATION STATUS
+
+### ✅ localStorage Key IS Correct
+
+Both WebSocket functions in `frontend/src/api/logs.ts` correctly use `charon_auth_token`:
+
+- **Line 119-122** (`connectLiveLogs`): `localStorage.getItem('charon_auth_token')`
+- **Line 178-181** (`connectSecurityLogs`): `localStorage.getItem('charon_auth_token')`
+
+---
+
+## 2. ALL ISSUES FOUND (NOW FIXED)
+
+### Issue #1: CRITICAL - Object Reference Instability in Props (ROOT CAUSE) ✅ FIXED
+
+**Problem:** `Security.tsx` passed `securityFilters={{}}` inline, creating a new object on every render. This triggered useEffect cleanup/reconnection on every parent re-render.
+
+**Fix Applied:**
+
+```tsx
+// frontend/src/pages/Security.tsx line 36
+const emptySecurityFilters = useMemo(() => ({}), [])
+
+// frontend/src/pages/Security.tsx line 421
+<LiveLogViewer mode="security" securityFilters={emptySecurityFilters} className="w-full" />
+```
+
+### Issue #2: Default Props Had Same Problem ✅ FIXED
+
+**Problem:** Default empty objects `filters = {}` in function params created new objects on each call.
+
+**Fix Applied:**
+
+```typescript
+// frontend/src/components/LiveLogViewer.tsx lines 138-143
+const EMPTY_LIVE_FILTER: LiveLogFilter = {};
+const EMPTY_SECURITY_FILTER: SecurityLogFilter = {};
+
+export function LiveLogViewer({
+  filters = EMPTY_LIVE_FILTER,
+  securityFilters = EMPTY_SECURITY_FILTER,
+  // ...
+})
+```
+
+### Issue #3: `showBlockedOnly` Toggle (INTENTIONAL)
+
+The `showBlockedOnly` state in useEffect dependencies causes reconnection when toggled. This is **intentional** for server-side filtering - not a bug.
+
+---
+
+## 3. ROOT CAUSE ANALYSIS
+
+### The Reconnection Loop (Before Fix)
+
+1. User navigates to Security Dashboard
+2. `Security.tsx` renders with `<LiveLogViewer securityFilters={{}} />`
+3. `LiveLogViewer` mounts → useEffect runs → WebSocket connects
+4. React Query refetches security status
+5. `Security.tsx` re-renders → **new `{}` object created**
+6. `LiveLogViewer` re-renders → useEffect sees "changed" `securityFilters`
+7. useEffect cleanup runs → **WebSocket closes**
+8. useEffect body runs → **WebSocket opens**
+9. Repeat steps 4-8 every ~100ms
+
+### Evidence from Docker Logs (Before Fix)
+
+```text
+{"level":"info","msg":"Cerberus logs WebSocket connected","subscriber_id":"xxx"}
+{"level":"info","msg":"Cerberus logs WebSocket client disconnected","subscriber_id":"xxx"}
+{"level":"info","msg":"Cerberus logs WebSocket connected","subscriber_id":"yyy"}
+{"level":"info","msg":"Cerberus logs WebSocket client disconnected","subscriber_id":"yyy"}
+```
+
+---
+
+## 4. COMPONENT DEEP DIVE
+
+### Frontend: Security.tsx
+
+- Renders the Security Dashboard with 4 security layer cards (CrowdSec, ACL, Coraza, Rate Limiting)
+- Contains multiple `useQuery`/`useMutation` hooks that trigger re-renders
+- **Line 36:** Creates stable filter reference with `useMemo`
+- **Line 421:** Passes stable reference to `LiveLogViewer`
+
+### Frontend: LiveLogViewer.tsx
+
+- Dual-mode log viewer (application logs vs security logs)
+- **Lines 138-139:** Stable default filter objects defined outside component
+- **Lines 183-268:** useEffect that manages WebSocket lifecycle
+- **Line 268:** Dependencies: `[currentMode, filters, securityFilters, maxLogs, showBlockedOnly]`
+- Uses `isPausedRef` to avoid reconnection when pausing
+
+### Frontend: logs.ts (API Client)
+
+- **`connectSecurityLogs()`** (lines 177-237):
+  - Builds URLSearchParams from filter object
+  - Gets auth token from `localStorage.getItem('charon_auth_token')`
+  - Appends token as query param
+  - Constructs URL: `wss://host/api/v1/cerberus/logs/ws?...&token=<jwt>`
+
+### Backend: routes.go
+
+- **Line 380-389:** Creates LogWatcher service pointing to `/var/log/caddy/access.log`
+- **Line 393:** Creates `CerberusLogsHandler`
+- **Line 394:** Registers route in protected group (auth required)
+
+### Backend: auth.go (Middleware)
+
+- **Lines 14-28:** Auth flow: Header → Cookie → Query param
+- **Line 25-28:** Query param fallback: `if token := c.Query("token"); token != ""`
+- WebSocket connections use query param auth (browsers can't set headers on WS)
+
+### Backend: cerberus_logs_ws.go (Handler)
+
+- **Lines 42-48:** Upgrades HTTP to WebSocket
+- **Lines 53-59:** Parses filter query params
+- **Lines 61-62:** Subscribes to LogWatcher
+- **Lines 80-109:** Main loop broadcasting filtered entries
+
+### Backend: log_watcher.go (Service)
+
+- Singleton service tailing Caddy access log
+- Parses JSON log lines into `SecurityLogEntry`
+- Broadcasts to all WebSocket subscribers
+- Detects security events (WAF, CrowdSec, ACL, rate limit)
+
+---
+
+## 5. SUMMARY TABLE
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| localStorage key | ✅ Fixed | Now uses `charon_auth_token` |
+| Auth middleware | ✅ Working | Accepts query param `token` |
+| WebSocket endpoint | ✅ Working | Protected route, upgrades correctly |
+| LogWatcher service | ✅ Working | Tails access.log successfully |
+| **Frontend memoization** | ✅ Fixed | `useMemo` in Security.tsx |
+| **Stable default props** | ✅ Fixed | Constants in LiveLogViewer.tsx |
+
+---
+
+## 6. VERIFICATION STEPS
+
+After any changes, verify with:
+
+```bash
+# 1. Rebuild and restart
+docker build -t charon:local . && docker compose -f docker-compose.override.yml up -d
+
+# 2. Check for stable connection (should see ONE connect, no rapid cycling)
+docker logs charon 2>&1 | grep -i "cerberus.*websocket" | tail -10
+
+# 3. Browser DevTools → Console
+# Should see: "Cerberus logs WebSocket connection established"
+# Should NOT see repeated connection attempts
+```
+
+---
+
+## 7. CONCLUSION
+
+**Root Cause:** React reference instability (`{}` creates new object on every render)
+
+**Solution Applied:** Memoize filter objects to maintain stable references
+
+**Logic Gap Between Frontend/Backend:** **NO** - Both are correctly aligned
+
+**Current Status:** ✅ All fixes applied and working
+
+---
+
+# Health Check 401 Auth Failures - Investigation Report
+
+**Date:** December 16, 2025
+**Status:** ✅ ANALYZED - NOT A BUG
+**Severity:** Informational (Log Noise)
+
+---
+
+## 1. INVESTIGATION SUMMARY
+
+### What the User Observed
+
+The user reported recurring 401 auth failures in Docker logs:
+```
+01:03:10 AUTH 172.20.0.1 GET / → 401 [401] 133.6ms
+{ "auth_failure": true }
+01:04:10 AUTH 172.20.0.1 GET / → 401 [401] 112.9ms
+{ "auth_failure": true }
+```
+
+### Initial Hypothesis vs Reality
+
+| Hypothesis | Reality |
+|------------|---------|
+| Docker health check hitting `/` | ❌ Docker health check hits `/api/v1/health` and works correctly (200) |
+| Charon backend auth issue | ❌ Charon backend auth is working fine |
+| Missing health endpoint | ❌ `/api/v1/health` exists and is public |
+
+---
+
+## 2. ROOT CAUSE IDENTIFIED
+
+### The 401s are FROM Plex, NOT Charon
+
+**Evidence from logs:**
+
+```json
+{
+  "host": "plex.hatfieldhosted.com",
+  "uri": "/",
+  "status": 401,
+  "resp_headers": {
+    "X-Plex-Protocol": ["1.0"],
+    "X-Plex-Content-Compressed-Length": ["157"],
+    "Cache-Control": ["no-cache"]
+  }
+}
+```
+
+The 401 responses contain **Plex-specific headers** (`X-Plex-Protocol`, `X-Plex-Content-Compressed-Length`). This proves:
+
+1. The request goes through Caddy to **Plex backend**
+2. **Plex** returns 401 because the request has no auth token
+3. Caddy logs this as a handled request
+
+### What's Making These Requests?
+
+**Charon's Uptime Monitoring Service** (`backend/internal/services/uptime_service.go`)
+
+The `checkMonitor()` function performs HTTP GET requests to proxied hosts:
+
+```go
+case "http", "https":
+    client := http.Client{Timeout: 10 * time.Second}
+    resp, err := client.Get(monitor.URL)  // e.g., https://plex.hatfieldhosted.com/
+```
+
+Key behaviors:
+- Runs every 60 seconds (`interval: 60`)
+- Checks the **public URL** of each proxy host
+- Uses `Go-http-client/2.0` User-Agent (visible in logs)
+- **Correctly treats 401/403 as "service is up"** (lines 471-474 of uptime_service.go)
+

+## 4. DOCKER HEALTH CHECK STATUS
+
+### ✅ Docker Health Check is WORKING CORRECTLY
+
+**Configuration** (from all docker-compose files):
+
+```yaml
+healthcheck:
+  test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:8080/api/v1/health"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+  start_period: 40s
+```
+
+**Evidence:**
+
+```
+[GIN] 2025/12/16 - 01:04:45 | 200 |     304.212µs |             ::1 | GET      "/api/v1/health"
+```
+
+- Hits `/api/v1/health` (not `/`)
+- Returns `200` (not `401`)
+- Source IP is `::1` (localhost)
+- Interval is 30s (matches config)
+
+### Health Endpoint Details
+
+**Route Registration** ([routes.go#L86](backend/internal/api/routes/routes.go#L86)):
+
+```go
+router.GET("/api/v1/health", handlers.HealthHandler)
+```
+
+This is registered **before** any auth middleware, making it a public endpoint.
+
+**Handler Response** ([health_handler.go#L29-L37](backend/internal/api/handlers/health_handler.go#L29-L37)):
+
+```go
+func HealthHandler(c *gin.Context) {
+    c.JSON(http.StatusOK, gin.H{
+        "status":      "ok",
+        "service":     version.Name,
+        "version":     version.Version,
+        "git_commit":  version.GitCommit,
+        "build_time":  version.BuildTime,
+        "internal_ip": getLocalIP(),
+    })
+}
+```
+
+---
+
+## 5. WHY THIS IS NOT A BUG
+
+### Uptime Service Design is Correct
+
+From [uptime_service.go#L471-L474](backend/internal/services/uptime_service.go#L471-L474):
+
+```go
+// Accept 2xx, 3xx, and 401/403 (Unauthorized/Forbidden often means the service is up but protected)
+if (resp.StatusCode >= 200 && resp.StatusCode < 400) || resp.StatusCode == 401 || resp.StatusCode == 403 {
+    success = true
+    msg = fmt.Sprintf("HTTP %d", resp.StatusCode)
+}
+```
+
+**Rationale:** A 401 response proves:
+- The service is running
+- The network path is functional
+- The application is responding
+
+This is industry-standard practice for uptime monitoring of auth-protected services.
+
+---
+
+## 6. RECOMMENDATIONS
+
+### Option A: Do Nothing (Recommended)
+
+The current behavior is correct:
+- Docker health checks work ✅
+- Uptime monitoring works ✅
+- Plex is correctly marked as "up" despite 401 ✅
+
+The 401s in Caddy access logs are informational noise, not errors.
+
+### Option B: Reduce Log Verbosity (Optional)
+
+If the log noise is undesirable, options include:
+
+1. **Configure Caddy to not log uptime checks:**
+   Add a log filter for `Go-http-client` User-Agent
+
+2. **Use backend health endpoints:**
+   Some services like Plex have health endpoints (`/identity`, `/status`) that don't require auth
+
+3. **Add per-monitor health path option:**
+   Extend `UptimeMonitor` model to allow custom health check paths
+
+### Option C: Already Implemented
+
+The Uptime Service already logs status changes only, not every check:
+
+```go
+if statusChanged {
+    logger.Log().WithFields(map[string]interface{}{
+        "host_name": host.Name,
+        // ...
+    }).Info("Host status changed")
+}
+```
+
+---
+
+## 7. SUMMARY TABLE
+
+| Question | Answer |
+|----------|--------|
+| What is making the requests? | Charon's Uptime Service (`Go-http-client/2.0`) |
+| Should `/` be accessible without auth? | N/A - this is hitting proxied backends, not Charon |
+| Is there a dedicated health endpoint? | Yes: `/api/v1/health` (public, returns 200) |
+| Is Docker health check working? | ✅ Yes, every 30s, returns 200 |
+| Are the 401s a bug? | ❌ No, they're expected from auth-protected backends |
+| What's the fix? | None needed - working as designed |
+
+---
+
+## 8. CONCLUSION
+
+**The 401s are NOT from Docker health checks or Charon auth failures.**
+
+They are normal responses from **auth-protected backend services** (like Plex) being monitored by Charon's uptime service. The uptime service correctly interprets 401/403 as "service is up but requires authentication."
+
+**No fix required.** The system is working as designed.

-
-2. **ESLint warnings (12 total):** All in test files or unrelated to the WebSocket auth fix.
-
----
-
-## Overall Status
-
-## ✅ PASS
-
-The WebSocket auth fix (`token` → `charon_auth_token`) has been verified:
-
-- ✅ No regressions introduced - All tests pass
-- ✅ Build integrity maintained - Both frontend and backend compile successfully
-- ✅ Type safety preserved - TypeScript checks pass
-- ✅ Code quality maintained - Lint passes (no new issues)
-- ✅ Coverage requirement met - 85.2% backend coverage
-
-The fix correctly aligns the WebSocket authentication with the rest of the application's token storage mechanism.
