## 🔴 Priority 1: Critical Blocking Tasks

### CCIP Selector and Bridge Configuration

- [ ] **T1.1: Verify ChainID 138 CCIP Selector**
  - **Current**: `5009297550715157269` (same as Mainnet - suspicious)
  - **Issue**: Different chains should have different selectors
  - **Action**: 
    1. Check Chainlink CCIP Directory: https://docs.chain.link/ccip/supported-networks
    2. Verify with custom router documentation (if custom CCIP)
    3. For custom: selector may be chain ID (`138`)
    4. Update `.env` with correct value
  - **Blocking**: Yes (blocks bridge configuration)

- [ ] **T1.2: Investigate ChainID 138 Bridge Configuration Block**
  - **Issue**: Execution reverted when configuring ChainID 138 → Mainnet
  - **Action**:
    1. Run `scripts/configuration/investigate-proxy-bridges.sh`
    2. Run `scripts/configuration/check-existing-destinations.sh`
    3. Check if destinations already configured via events
    4. Verify admin permissions on ChainID 138 contracts
  - **Blocking**: Yes (blocks bidirectional configuration)

- [ ] **T1.3: Complete Bidirectional Bridge Configuration**
  - **Status**: 50% complete (Mainnet → ChainID 138 done)
  - **Dependencies**: T1.1, T1.2
  - **Action**:
    1. Once selector verified: `scripts/configuration/configure-chain138-to-mainnet.sh`
    2. Verify: `scripts/configuration/verify-bridge-configuration.sh`
  - **Blocking**: Yes (blocks full bridge functionality)
