OBSERVATIONAL LIFECYCLE
Native decimal operations with a C interface and C++ wrapper.
ORIGIN AND CANDIDATE
Preserve request, source identity and anticipated context. A proposal or forecast is not an acquired observation.
EVIDENCE INTAKE
A supported decimal operation is requested through the native or R interface.
BOUNDED TRANSFORMATION
Preserve representation, rounding and ownership rules and compare behavior with the matching numeric contract.
RESULT AND RECONCILIATION
Return the precise supported result or named failure without expanding the arithmetic guarantees.
STATE PROFILE RULE
Identify the applicable R/R0/R1/N1-N9/R2 profile before assigning state labels. Historical R1 meanings differ; lower-case neural r0/r9 is separate from runtime R-states and MjQ states. Preserve the original event, missing prerequisite and each later correction.
REENTRY CHALLENGE
Exercise an exact decimal boundary and an overflow across the C and C++ interfaces; compare values and explicit failure contracts without binary floating-point substitution.
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.
