// Quality Intelligence — model-routed test-design prompt assembly (Epic #270, Issue #279/#272).
//
// Pure construction of the trusted instruction + the JSON response contract that the
// model-routed test-design path sends through the Keiko Model Gateway. NO IO, NO model
// call, NO randomness: this module only produces strings + a JSON-schema object. The
// server tier feeds the untrusted evidence segments separately so trusted instructions
// and untrusted source text never share a string (ADR-0023 D5, Issue #284).
import { regressionDefault } from "../domain/policyProfile.js";
// The trusted system instruction. Pinned, never interpolates untrusted content. Frames the
// model as a regulated-delivery QA engineer and fixes the output contract to STRICT JSON so
// the deterministic parser can recover candidates without free-text heuristics.
