Step 3: Label Selected Statuses

The mapping assigns a neutral review_class to records retained by the previous stage.

Reference configuration

pipeline:
  processors:
    - mapping: |
        root.review_class = match {
          this.adapter_status == 2 => "status-2"
          this.adapter_status == 1 => "status-1"
          _ => "unclassified-status"
        }

These strings are deterministic grouping labels, not a diagnostic model. They deliberately avoid assigning physical fault or severity meaning.

Review before implementation

• Replace the status mapping with site-owned definitions.
• Define handling for missing, malformed, and undocumented status values.
• Keep review labels separate from protection and control functions.
• Add a correlation stage before any rule that depends on several registers.
