IF / HOW / THEN CONTRACT
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.
TYPED EVIDENCE
- DecimalValue — exact representation and scale
- NumericOperation — supported operation and rounding rule
- MemoryContract — owner and lifetime
- NumericEvidence — expected result and test profile
FAILURE AND MISSINGNESS
Preserve UNKNOWN separately from zero and source identity separately from truth. Missing required evidence remains a typed error or HOLD under the named profile. Failed permission remains DENY.
PROJECT CHALLENGE
Round-trip a long decimal through the native and R boundaries; preserve exact representation and report unsupported range without silent rounding.
RECONCILIATION
Append later results or discrepancies to the original evidence; do not rewrite a prediction into an earlier observation.
DISCOVERY NAMES
R jpdecimal
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 released integration; precise numeric semantics depend on the native-library contract. Historical evidence has not been rerun in this discovery pass.
