# Golden Subjects

> Use when writing or maintaining a DecimalSubject adapter or any golden-harness integration — adding a subject for a new decimal library to golden-competitors, fixing an existing adapter's limits/rounding/overflow declarations, or wiring a library against the decimal-scaled-golden golden set. Covers the typed-vs-erased choice, the Capabilities/FnSupport contract, value-aware limits, round-trip rules, panic capture, the gotchas hit building the seven competitor adapters, and how to validate a new subject.
