Prefer Explicit Projection

When normalizing/querying, keep output schemas deterministic and readable:

• Prefer explicit output selection (project / project-keep) over project-away, so adding new columns later won’t accidentally change results.
• Consolidate related extend operations into fewer, clearer steps; remove redundant helper columns that don’t affect the final output.
• Avoid brittle fixed-position array access (e.g., TargetResources[0]); use parsing/where/structured extraction so logic doesn’t depend on unreliable ordering.

Example (avoid project-away):

// Prefer explicit projection
... 
| project
    TimeGenerated,
    EventUid,
    DvcIpAddr,
    EventSchema,
    EventSchemaVersion,
    EventMessage,
    AdditionalFields
// (Do not rely on project-away for final output stability)

Example (combine extends):

... 
| extend timestamp=TimeGenerated,
         HostName = tostring(split(DeviceName, '.', 0)[0]),
         DnsDomain = tostring(strcat_array(array_slice(split(DeviceName, '.'), 1, -1), '.'))

Example (avoid positional indexing):

• Replace TargetResources[0]-style access with parsing/filters that locate the correct element by key/value rather than index.
