[Payer Report Testing] Alerting - per-environment alerts for sync, attestation, and submission failures #1685
Description
Description
Set up alerting per environment (dev, staging, testnet, mainnet) covering:
- Sync issues (sequence ID gaps, replication lag)
- Attestation failures (nodes failing to submit payer reports)
- Submission failures (settlement transactions failing)
Cross-check using last sequence ID per originator ID as source of truth. This is the last line of defense before something goes to testnet/mainnet.
Acceptance Criteria
- Alerts fire on sync issues per environment
- Alerts fire on attestation failures per environment
- Alerts fire on submission failures per environment
- Cross-check uses last sequence ID per originator ID
- Alerts validated in both dev and staging environments
