/**
 * Claude Code's answer to "is a real model reachable, and on whose bill" — the

 *
 * 🔴 IT USED TO LIVE IN `src/scan-trigger-suggest.ts`, the module named for the
 * harness-AGNOSTIC read-vs-run decision, and its whole body was one harness's
 * environment variables. The CLI then paired it with a name check for the other
 * harness (`adapter.name === "codex" || hasModelAccess(process.env)`), which is
 * the same fact said twice in two vocabularies. Here it is one adapter's
 * knowledge of its own credentials, and the CLI asks the port.
 *
 * A tiny env-only predicate, never a live probe: deciding whether to offer a
 * measurement must not itself spend a token.
