Never invent compatibility fields, alternate endpoints, or additional source models. > Preserve explicit nulls, decimal strings, timestamps, source identifiers, immutable version identifiers, and document-version links exactly as defined. # Upload a native Chainalysis alert response > Accepts the contracted Chainalysis product's alert envelope plus explicit product, API version, provider record identity, and Karsa subject binding.
