+  # The "evm-e2e-cron" job runs end-to-end tests on a schedule against instances
+  # of Nibiru to ensure core functionality remains stable. This is intended to
+  # highlight any outage or catch degredations in public endpoint functionality
+  # early. Failures trigger immediate Slack notifications to alert the team.
+  #
+  # This workflow:
+  # 1. Executes basic EVM integration tests against the testnet
+  # 2. Uses a dedicated test wallet (configured via secrets)
+  # 3. Reports failures to the testnet Slack channel
+  #
+  # Environment requirements:
+  # - WALLET_MNEMONIC_TESTNET: Secret for test wallet access
+  # - SLACK_WEBHOOK_TESTNET: Webhook URL for failure notifications
