Specification & Structural Breakdown

Technical Rule Summary: Implementation conforms strictly to ANSI ASC X12 Standards (005010). Data ingestion is fully deterministic: identical inputs always produce bit-for-bit identical outputs without ambient side-effects.

Translates hierarchical 835 ERA remittance loops into flat rows suitable for Excel, Google Sheets, or SQL bulk inserts.

Flattens CLP claim payment loops, SVC service lines, CAS contractual adjustments, and BPR check/EFT transaction details.

Runs with zero data retention on Cloudflare V8 edge compute.
