+## 🔑 Important Findings
+
+### 1. Built-in Custom Server Support
+
+**Discovery:** RR3 has **native support** for custom servers via `NimbleConfiguration.CUSTOMIZED`
+
+**Location:** `SynergyEnvironmentImpl.java` lines 166-183
+
+**Impact:** No need for complex code modifications - just change AndroidManifest.xml!
+
+### 2. Configuration Modes
+
+| Mode | Usage | Server URL |
+|------|-------|------------|
+| LIVE | Production (default) | `syn-dir.sn.eamobile.com` |
+| STAGE | Testing | `director-stage.sn.eamobile.com` |
+| INTEGRATION | Development | `director-int.sn.eamobile.com` |
+| **CUSTOMIZED** | **Community** | **User-defined** |
+
+### 3. Protocol Specifications
+
+**Transport:** HTTPS (HttpURLConnection)  
+**Format:** JSON request/response  
+**Headers:** `EAM-SESSION`, `EAM-USER-ID`, `EA-SELL-ID`, `SDK-VERSION`  
+**Authentication:** Session-based (UUID)  
+**SSL:** Custom certificate validation (can be disabled)
