PURPOSE AND PROJECT PLACEMENT
Native decimal operations with a C interface and C++ wrapper.

IDENTITY AND RELATIONSHIPS
Related identities: Bangel Interoperability; R jpdecimal. Preserve each named contract and source status.

REQUEST TO RESULT
IF
A supported decimal operation is requested through the native or R interface.

HOW
Preserve representation, rounding and ownership rules and compare behavior with the matching numeric contract.

THEN
Return the precise supported result or named failure without expanding the arithmetic guarantees.

RELEASE REQUIREMENT
Bind inputs, decisions and results to the exact source profile. Preserve reproducible procedure, expected behavior, observed outcome and reviewer. Documentary completion does not substitute for implementation or execution evidence.

DISCOVERY NAMES
JP C++ Decimal Library
These names aid search; current compiler naming remains Elsa.

SOURCE STATUS AND LIMITS
Recovered historical design and project records informed this documentary profile. Original conversations remain private; current implementation and reported historical tests were not rerun.
Recovered status: historical_report_not_fresh_verification.
Historical integration source; numeric behavior and memory ownership must stay tied to its specific contract. Historical evidence has not been rerun in this discovery pass.
