 ### Issue: Build failing due to corrupted Android SDK
-- The SDK at /opt/android-sdk is corrupted (duplicate platform directories)
-- Cannot clean up without sudo access on the laptop
-- Need to either: (1) have Stefy run cleanup, or (2) find alternative build method
+- The SDK at /opt/android-sdk is corrupted (duplicate platform directories: android-34, android-34-2, android-34-6, etc.)
+- Each build attempt creates a new duplicate directory
+- The platform files show wrong version (Platform 14 inside android-34 folder)
+- **CANNOT fix without sudo access** on the laptop
+- Need: `sudo rm -rf /opt/android-sdk/platforms/* && sudo sdkmanager "platforms;android-34" "build-tools;34.0.0"`
 
 ### Error: Client ID format for pairing
 - Original log showed: `invalid connect params: at /client/id: must be equal to constant`
-- **MISTAKE**: Changed client.id from device hash to "android-node" constant
-- **CORRECTION**: Reverted back to using deviceId hash - the constant was WRONG
-- The real issue is likely something else in the connect params
+- Protocol docs show `id: "ios-node"` for iOS - so "android-node" SHOULD be valid
+- **MISTAKE**: Tried changing to "android-node" but user confirmed original device hash was correct
+- **REVERTED**: Changed back to using deviceId hash
+- Real issue is likely something else in the connect params
 
 ### Code Changes Made
-1. **Hardcoded gateway config** (temporary for testing):
+1. **Hardcoded gateway config** (TEMPORARY for testing):
    - File: `NodeService.kt`
    - Added fallback config: IP=192.168.11.46, port=18789, token=<gateway token>
-   - This is TEMPORARY - should be removed after pairing works
+   - **MUST REMOVE** after pairing works
 
 2. **Client ID**: Kept as deviceId hash (not constant)
 
 ### Next Steps
-1. Need to fix SDK issue to build
-2. Need to debug actual pairing flow error
+1. **BLOCKED**: Need SDK cleanup on laptop before can build - cannot fix without sudo
+   - Each build creates a new duplicate (android-34-7 now)
+   - Gradle/SDK manager is confused by the duplicates
+2. After build: test pairing flow
 3. After pairing works: remove hardcoded config, test on real phone
