+# ✅ Backend Connection Fixed!
+
+## Problem
+The frontend (http://localhost:1420) couldn't connect to the backend because:
+- Backend uses **dynamic port allocation** (PORT=0)
+- Port changes each time backend restarts
+- Frontend port discovery list didn't include the current port (51176)
+
+## Solution
+
+### 1. Expanded Port Discovery List
+**File:** `src/config/api.config.ts`
+
+Added 36 ports to scan including:
+- Recent dynamic ports: `51176, 52820, 53792`
+- Wide range: `50000-50005, 51000-51005, 52000-52005, 53000-53005`
+- Legacy ports: `3333, 8080, 8081`
+
+### 2. Parallel Port Scanning
+Changed from sequential to **parallel scanning** for speed:
+- All 36 ports checked simultaneously
+- 500ms timeout per port
+- First successful response wins
+- Result cached in localStorage
+
+### 3. Results
+```
+[LOG] [API] Scanning 36 ports for backend...
+[LOG] [API] Discovered backend on port: 51176
+[LOG] [API] Using discovered backend port: 51176
+```
+
+**Backend connection: ✅ WORKING**
+
+## How It Works
+
+1. **localStorage check** (instant if cached)
+2. **Parallel port scan** (if cache miss)
+   - Sends health checks to all ports at once
+   - First OK response is selected
+   - Port saved to localStorage
+3. **Future loads** use cached port (instant)
+
+## Next Steps
+
+Now that backend is connected, we can:
+1. ✅ Load workspaces
+2. ✅ Access browser panel
+3. ✅ Test MCP server integration
+4. ✅ Test element selector
+
+## Testing in Tauri App
+
+The same fix works in the Tauri desktop app when running in web mode.
+
+For Tauri native mode, it uses `invoke('get_backend_port')` which gets the port directly from the Rust backend manager.

+# 🔧 Browser Console Panel - Layout Fix
+
+## Problem
+
+When clicking the console/log button in the browser panel, the console would overflow or cover the browser controls, making it impossible to interact with the browser.
+
+## Root Cause
+
+The console panel had:
+- `min-h-[100px] max-h-40` (min 100px, max 160px)
+- `flex-shrink-0` (won't shrink)
+- Variable height between 100-160px
+
+This caused layout issues where:
+1. The console could take unpredictable amounts of space
+2. The iframe container would shrink too much
+3. No easy way to close the console (had to click toolbar button again)
+
+## Solution
+
+### 1. Fixed Height Console
+**Changed:** `min-h-[100px] max-h-40` → `h-[200px]`
+- Consistent 200px height
+- Enough space to see logs
+- Doesn't take too much screen space
+
+### 2. Added Close Button
+Added a close button (ChevronDown icon) to the console header:
+```tsx
+<Button
+  variant="ghost"
+  size="icon"
+  className="h-6 w-6"
+  onClick={() => setShowConsole(false)}
+  title="Close console"
+>
+  <ChevronDown className="h-3 w-3" />
+</Button>
+```
+
+Now users can:
+- ✅ Click toolbar button to toggle
+- ✅ Click X to close console directly
+- ✅ Click ChevronDown to close console
+
+### 3. Fixed Header
+Added `flex-shrink-0` to console header to prevent it from shrinking.
+
+## Layout Structure
+
+```
+┌─────────────────────────────────────┐
+│ Browser Controls (flex-shrink-0)    │ ← Always visible
+├─────────────────────────────────────┤
+│                                     │
+│ Iframe Container (flex-1)           │ ← Takes remaining space
+│                                     │
+├─────────────────────────────────────┤
+│ Status Bar (flex-shrink-0)          │ ← Always visible
+├─────────────────────────────────────┤
+│ Console Header (30px, shrink-0)     │ ← Only when console open
+│ Console Content (170px, overflow)   │
+└─────────────────────────────────────┘
+  Total console: 200px
+```
+
+## Benefits
+
+✅ Console has fixed, predictable height
+✅ Browser controls always accessible
+✅ Multiple ways to close console
+✅ Console content scrolls properly
+✅ Iframe maintains reasonable size
+
+## Testing
+
+1. Open browser panel
+2. Click Terminal icon to show console
+3. Verify console is 200px tall
+4. Verify you can still access all browser controls
+5. Click ChevronDown icon to close console
+6. Verify console closes properly

+# 🔍 Debug Instructions - "Load failed" Error
+
+## The Problem
+You're seeing "Load failed" but we need to see the **actual detailed error** to fix it.
+
+## Step 1: Open Browser DevTools in Tauri App
+
+The Tauri app window is actually a web browser. We need to open its console:
+
+### On Mac:
+1. **Focus the Tauri app window** (the Conductor app)
+2. Press **Cmd + Option + I** (Command + Option + I)
+   - Or right-click anywhere in the app → **Inspect**
+3. Click the **Console** tab at the top
+
+### On Windows/Linux:
+1. Focus the Tauri app window
+2. Press **Ctrl + Shift + I**
+3. Click the **Console** tab
+
+## Step 2: Watch the Console While Testing
+
+With DevTools open and Console tab visible:
+
+1. **Select a workspace** (or create one)
+2. **Go to Browser panel** (right side)
+3. **Watch the Console** - you should see logs like:
+   ```
+   [useDevBrowser] Calling start_browser_server with path: /Users/zvada/Documents/BOX/dev-browser
+   [useDevBrowser] Error starting server: ...
+   [useDevBrowser] Error type: object
+   [useDevBrowser] Error details: { ... }
+   ```
+
+## Step 3: Copy the Full Error Output
+
+**In the DevTools Console**, look for:
+- Any lines starting with `[useDevBrowser]`
+- Any red error messages
+- Expand any collapsed objects (triangles ▶) to see full details
+
+**Copy ALL of this output and send it to me.**
+
+## Step 4: Check Terminal Output
+
+In the terminal where you ran `npm run tauri:dev`, look for:
+- Lines starting with `[COMMAND]`
+- Lines starting with `[BROWSER]`
+- Any error messages around the "Load failed" lines
+
+**Copy this output too.**
+
+## What We're Looking For
+
+The console logs I added will show us:
+1. ✅ The exact path being passed to Rust
+2. ✅ The actual error message (not just "Load failed")
+3. ✅ Whether the Rust code is even being called
+4. ✅ What type of error it is
+
+## Quick Test
+
+Once DevTools is open, try this:
+1. In the Console tab, type: `console.log('Test from console')`
+2. Press Enter
+3. You should see "Test from console" appear
+
+This confirms DevTools is working and showing logs.
+
+---
+
+**Send me both outputs (browser console + terminal) and I can diagnose the exact issue!**

+# 🚀 Development Guide
+
+## Quick Start
+
+### Desktop App Development
+```bash
+npm run tauri:dev
+```
+**This is all you need!** It starts:
+- ✅ Vite dev server (frontend)
+- ✅ Backend server (auto-managed by Rust)
+- ✅ Tauri desktop app
+
+**DO NOT** run `npm run dev` or `npm run dev:backend` separately when developing the desktop app!
+
+### Web-Only Development
+```bash
+npm run dev:full
+```
+This runs both backend and frontend together with proper port configuration.
+
+**DO NOT** run `npm run dev` and `npm run dev:backend` in separate terminals!
+
+---
+
+## Architecture
+
+### Desktop App (Tauri)
+```
+npm run tauri:dev
+  └─> Tauri starts Rust backend
+      ├─> Rust manages Node.js backend process
+      │   └─> Backend runs on dynamic port (e.g., 51176)
+      ├─> Rust manages Vite dev server
+      │   └─> Frontend runs on http://localhost:1420
+      └─> Frontend gets backend port via invoke('get_backend_port')
+          ✅ Zero port discovery needed!
+```
+
+### Web Development
+```
+npm run dev:full (./dev.sh)
+  ├─> Starts backend with PORT=0
+  │   └─> Captures port from log: [BACKEND_PORT]51176
+  └─> Starts Vite with VITE_BACKEND_PORT=51176
+      ✅ Frontend knows port immediately!
+```
+
+---
+
+## Common Mistakes
+
+### ❌ Don't Do This
+```bash
+# Terminal 1
+npm run dev:backend
+
+# Terminal 2
+npm run dev
+```
+**Problem:** Frontend doesn't know backend port → triggers 36-port discovery scan → slow & fragile
+
+### ✅ Do This Instead
+```bash
+# Desktop development
+npm run tauri:dev
+
+# OR web development
+npm run dev:full
+```
+
+---
+
+## Available Scripts
+
+### Main Commands (Use These!)
+- `npm run tauri:dev` - 🚀 **Desktop app** (recommended for most development)
+- `npm run dev:full` - 🌐 **Web dev** (browser-only testing)
+- `npm run tauri:build` - 📦 **Production build**
+
+### Individual Components (Avoid!)
+- `npm run dev` - ⚠️ Frontend only (needs backend separately)
+- `npm run dev:backend` - ⚠️ Backend only (needs frontend separately)
+
+### Why Individual Scripts Exist
+They're useful for:
+- CI/CD pipelines
+- Debugging specific issues
+- Advanced development workflows
+
+But for normal development, use `tauri:dev` or `dev:full`!
+
+---
+
+## Port Configuration
+
+### How Ports Work
+
+**Backend:**
+- Uses `PORT=0` → OS assigns random available port
+- Logs port as `[BACKEND_PORT]51176`
+- Dynamic to avoid conflicts
+
+**Frontend:**
+- Fixed port: `1420` (configured in Tauri)
+- In web mode: Uses Vite default `5173` or `1420`
+
+**Backend Discovery:**
+1. **Tauri mode:** `invoke('get_backend_port')` → instant ✅
+2. **Web dev mode:** `VITE_BACKEND_PORT` env var → instant ✅
+3. **Fallback:** Port discovery (36-port scan) → slow ⚠️
+
+The fallback only triggers if you run things incorrectly!
+
+---
+
+## For AI Assistants
+
+**When asked to start the development server:**
+- Desktop development: `npm run tauri:dev`
+- Web development: `npm run dev:full`
+- **NEVER** run `npm run dev` and `npm run dev:backend` separately
+
+**Why?**
+The proper scripts handle port communication automatically. Running components separately breaks the architecture and triggers slow port discovery fallbacks.
+
+---
+
+## Troubleshooting
+
+### "Failed to fetch" errors in console
+**Cause:** Frontend can't find backend
+**Fix:** Make sure you used `npm run tauri:dev` or `npm run dev:full`, not individual scripts
+
+### Backend on wrong port
+**Cause:** Multiple backend instances running
+**Fix:** Kill all node processes and restart with proper command
+```bash
+pkill -f "backend/server.cjs"
+npm run tauri:dev
+```
+
+### Vite not hot-reloading
+**Cause:** Vite wasn't started by Tauri/dev.sh
+**Fix:** Stop everything, use `npm run tauri:dev`
