R jpdecimal - Observational lifecycle

Recovered historical or requested identity — documentary reconstruction; execution not rerun

R jpdecimal / Brown

MJ Physics Engineering | Bangel Language | MJos Operating System
Owned and operated by Michael Bangel | Clearwater, Florida

OBSERVATIONAL LIFECYCLE

R package exposing the native decimal library.

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

Round-trip a long decimal through the native and R boundaries; preserve exact representation and report unsupported range without silent rounding.

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.
