**Date**: 2025-01-18  
**Status**: Historical task-completion snapshot  
**Total Tasks**: 14

This report captures an earlier project milestone and should be read as historical context, not as a current operator status page.

## Completion Summary

**Completed Tasks**:
1. ✅ Task 5: Host Token List Publicly
2. ✅ Task 6: Verify TransactionMirror on Etherscan  
3. ✅ Task 8: Verify Environment Variables
4. ✅ Task 9: Verify Ledger App-Ethereum RPC Endpoints

### ⏳ Blocked (RPC Access Required): 3/14 Tasks (21%)

**Blocked Tasks**:
1. ⏳ Task 1: Verify ChainID 138 Contracts (Requires ChainID 138 RPC access)
2. ⏳ Task 4: Perform Cross-Chain Integration Testing (Requires RPC + Services)
3. ⏳ Task 7: Verify Bridge Destination Configurations (Requires ChainID 138 RPC access)

**Reason**: ChainID 138 RPC endpoint not accessible from this environment.

**Solution**: Use public RPC endpoints (`https://rpc-http-pub.d-bis.org`) when network access is available.
