IF
This Elsa / source module is imported or its declared interface is invoked. Declared surface includes: private
readonly record struct Exact(BigInteger Coefficient, int Exponent, bool NegativeZero = false); internal static
BangelDecimal Parse(string text); internal static BangelDecimal Round28(BangelDecimal value) =>; internal
static BangelDecimal Round34(BangelDecimal value) => value.Round();; internal static BangelDecimal
Round34(string text)
HOW
Preserve lexical, syntactic, binding, type and lowering behavior before producing a validated representation.
The complete terminology-edited 338-line source is preserved with SHA-256
4be7db7fbd240b4d3975a47e762857acdbb8562415e0c365a0d1124e69b94a8e. 31 extracted
function/declaration entries are separately indexed, including exact Python bodies and guards where
available.
THEN
Follow the exact returned values, diagnostics and state effects in the preserved implementation. Module
inclusion and syntax extraction are documentary coverage; they do not prove every branch or cross-host
behavior.
CURRENT EVIDENCE
Fresh related Python suites and per-profile/water results are included. Native C#/.NET, C++/Rust/R
compilation and physical devices were not executed in this environment.
REMAINING REQUIREMENT
Map unverified branches and native-host behavior to source-specific evidence before assigning a complete verification verdict.
