14.34Collection partial failures

Suppose API processes:

3 records

Input:

C001 valid

C002 missing required field

C003 valid

If contract allows partial success, verify:

{
  "processed": 3,
  "succeeded": 2,
  "failed": 1
}

and Salesforce:

C001 exists
C002 absent
C003 exists

The response alone isn't enough.
