Reword how the **`prototype`** skill lets go of its artifacts around a single idea: **the prototype is a primary source**. Rather than being deleted once it's answered its question, the prototype is kept as runnable evidence on a throwaway branch (`prototype/<name>`) linked from the relevant issue, never merged, so the main branch keeps only the validated decision. The answer (verdict + question) is still captured durably in an issue/ADR/commit.
