Generate Deduplication Hashes for Batch Records

Stratford Manufacturing relies on a System API to ingest production batch data safely into their core database. You will transform an incoming JSON payload of batch records, utilizing cryptographic functions to generate a unique composite checksum for each record, ensuring idempotent database insertions and preventing duplicate entries.
