Overview

Pure algorithm: Build notification payloads for baseline anomaly alerts

No HTTP calls — accepts error + anomaly data, returns platform-specific Hashes.

Examples:

BaselineAlertPayloadBuilder.slack_payload(error_log, anomaly_data)
BaselineAlertPayloadBuilder.discord_payload(error_log, anomaly_data)
BaselineAlertPayloadBuilder.webhook_payload(error_log, anomaly_data)
