Improve Infra Ops

Goal

Correct the selected runtime configuration or delivery path and verify the affected startup, failure or recovery behavior.

Domain rules

• Keep configuration ownership singular and fail safely on missing or incompatible critical values.
• Make readiness distinct from process liveness and include graceful drain/cancel for accepted work.
• Bound retries, pools, queues, memory, and downstream concurrency; expose saturation and recovery.
• Update CI/deploy config, examples, tests, runbooks, alerts, and rollback instructions directly affected.

Validation

• Run repository-native config/build/smoke/lifecycle checks and render generated deployment artifacts.
• Exercise restart, missing config/secret, degraded dependency, drain, and rollback where safe.
• List environment-only IAM/network/provider gates precisely.

Correct the maintained configuration, delivery script or runtime lifecycle owner and regenerate direct artifacts. Validate the same candidate/target inputs and replay its selected startup/dependency/drain failure with a healthy control. Recheck failures at that owner, then finish Patch Checking. Execute a live release or state-changing recovery only through the user's authorized mechanism; otherwise return the validated setup and exact remaining external action.
