defiQUG 1fb7266469 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.

Oracle Operations Runbook

Overview

This runbook provides procedures for operating and maintaining the oracle system.

Oracle Update Procedures

Manual Oracle Update

Check current oracle state:

cast call $AGGREGATOR_ADDRESS "latestRoundData()" --rpc-url $RPC_URL

Update oracle:

cast send $AGGREGATOR_ADDRESS "updateAnswer(uint256)" $PRICE \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY

Verify update:

cast call $AGGREGATOR_ADDRESS "latestAnswer()" --rpc-url $RPC_URL

Automated Oracle Updates

Oracle updates are automated via the oracle publisher service:

# Check oracle publisher status
kubectl get pods -n besu-network -l app=oracle-publisher

# View logs
kubectl logs -n besu-network -l app=oracle-publisher --tail=100

# Restart if needed
kubectl rollout restart deployment/oracle-publisher -n besu-network

Oracle Troubleshooting

Oracle Not Updating

Check transmitter status:

cast call $AGGREGATOR_ADDRESS "isTransmitter(address)" $TRANSMITTER_ADDRESS --rpc-url $RPC_URL

Check oracle publisher:

kubectl logs -n besu-network -l app=oracle-publisher

Check heartbeat:

cast call $AGGREGATOR_ADDRESS "heartbeat()" --rpc-url $RPC_URL

Oracle Price Deviation

Check deviation threshold:

cast call $AGGREGATOR_ADDRESS "deviationThreshold()" --rpc-url $RPC_URL

Review price sources:
- Check data source health
- Verify aggregation logic
- Review recent updates

Oracle Recovery Procedures

Recover from Stale Oracle

Identify stale oracle:

cast call $AGGREGATOR_ADDRESS "latestRoundData()" --rpc-url $RPC_URL

Force update:

cast send $AGGREGATOR_ADDRESS "updateAnswer(uint256)" $PRICE \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY

Recover from Failed Transmitter

Remove failed transmitter:

cast send $AGGREGATOR_ADDRESS "removeTransmitter(address)" $TRANSMITTER \
  --rpc-url $RPC_URL \
  --private-key $ADMIN_KEY

Add new transmitter:

cast send $AGGREGATOR_ADDRESS "addTransmitter(address)" $NEW_TRANSMITTER \
  --rpc-url $RPC_URL \
  --private-key $ADMIN_KEY

Monitoring

Key Metrics

Oracle update frequency
Price deviation
Transmitter availability
Update success rate

Alerts

Oracle update stale (> 5 minutes)
Price deviation > 5%
Transmitter unavailable
Update failures

Best Practices

Regular Monitoring: Check oracle status daily
Backup Transmitters: Maintain multiple transmitters
Price Source Diversity: Use multiple data sources
Automated Updates: Rely on oracle publisher service
Incident Response: Follow incident response procedures
