Zero-Server WebAssembly & Mainframe Oracle Verification
We compiled the actual US Federal Medicare COBOL Pricer sources into native x86 binaries and differential-fuzzed them against our zero-allocation WebAssembly engines. Cent-for-cent ($0.00) mathematical match across 100,000+ claims.
Deconstructs complex COBOL memory grids (OCCURS, INDEXED BY, SEARCH ALL) into visual multi-sheet workbooks with real-time =XLOOKUP and algebraic formula reduction.
Inpatient & outpatient End-Stage Renal Disease PPS rate engine. Calculates Body Surface Area (Mosteller), BMI adjustments, CBSA wage indexes, comorbidities, and outlier thresholds.
Long-Term Care Hospital Prospective Payment System. Evaluates Standard Federal Rates ($43,755), Short-Stay Outliers (SSO 4-way evaluation), High-Cost Outliers (HCO), and Site-Neutral IPPS comparisons.
Differential Fuzzing execution test: COBOL Binary (GnuCOBOL) vs CobolIQ AST-SLS Engine (WASM/Rust).
