GATE

A supported decimal operation is requested through the native or R interface.
Required scope, evidence identity, input shape and applicable independent review must be present.

SENTINEL

Preserve representation, rounding and ownership rules and compare behavior with the matching numeric contract.
Watch stale evidence, changed source roots, unsupported type conversions and requests beyond the named profile.

AUDIT RECEIPT

Record request identity, source version, assumptions, input, proposed result, actual outcome and reasons for HOLD or DENY. One successful stage does not override another's veto.

SPECIFIC 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.

BOUNDED RESULT

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

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.
