Add Oracle Aggregator and CCIP Integration
- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control. - Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities. - Created .gitmodules to include OpenZeppelin contracts as a submodule. - Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment. - Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks. - Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring. - Created scripts for resource import and usage validation across non-US regions. - Added tests for CCIP error handling and integration to ensure robust functionality. - Included various new files and directories for the orchestration portal and deployment scripts.

||||
|
||||
## ✅ Review Complete
|
||||
|
||||
### Contracts Reviewed
|
||||
1. ✅ **MainnetTether.sol** - State proof anchoring
|
||||
2. ✅ **TransactionMirror.sol** - Transaction mirroring
|
||||
3. ✅ **DeployMainnetTether.s.sol** - Deployment script

## 🔧 Fixes Applied
|
||||
|
||||
### TransactionMirror.sol
|
||||
|
||||
1. **✅ Added MAX_BATCH_SIZE Constant**
|
||||
- Set to 100 transactions per batch
|
||||
- Prevents gas limit issues
|
||||
|
||||
2. **✅ Added Empty Batch Validation**
|
||||
- Prevents wasteful empty batch calls
|
||||
|
||||
3. **✅ Fixed Stack Too Deep Error**
|
||||
- Created `BatchTxInput` struct to reduce function parameters
|
||||
- Refactored `_mirrorSingleTransaction` to use struct
|
||||
- Successfully compiles
|
||||
|
||||
4. **✅ Simplified Block Range Calculation**
|
||||
- Removed unnecessary length checks
