/**
 * Exports a before/after pair as a suite somebody else's harness can run.
 *
 * `trazum eval` answers "does the model still say the same thing?" — semantic
 * agreement, measured against the model's own variance. That is the question
 * Trazum is qualified to ask, and it is not the question a team actually needs
 * answered before shipping. *Their* question is whether the classifier still
 * hits 94%, whether the JSON still parses, whether the refusal rate moved. Those
 * are assertions about their task, and Trazum has no business inventing them.
 *
 * So this hands over the part it *can* build correctly — a suite in which the
 * only variable is the prompt, with both versions and every case already wired
 * — and leaves the assertions where they belong.
 *
 * ## Why JSON rather than YAML
 *
 * promptfoo reads `promptfooconfig.json` as readily as the YAML. This package
 * has no dependencies and is not going to acquire a YAML emitter, and a
 * hand-rolled one would be a quoting bug waiting for the first prompt
 * containing a colon, a tab, or a line ending in a space. `JSON.stringify`
 * escapes everything correctly, and JSON is a subset of YAML, so the file can
 * be renamed if somebody prefers.
