//
// "Release-green" pre-flight validator (Solution C).
//
// WHY: the full gate (ci.yml — unit shards, vitest, ratchets, package-artifact)
// runs ONLY on the release PR (PR → main). PRs into release/** only get the
// fast-gates (quality.yml: TIA-impacted tests + typecheck + lint checks). So
// reds accumulate silently on the release branch and explode — in layers — at
// release time. This script reproduces the release-equivalent validation against
// the CURRENT working tree so the maintainer (or the nightly, Solution D) can see
// the real state of the release branch at any time.
//
// DESIGN — never blocking to contributors:
//   • HARD checks (typecheck, lint errors, db-rules, public-creds, docs-all,
//     unit, vitest, integration, optionally package-artifact) → a failure here is
//     a real defect; exit 1.
//   • DRIFT checks (eslint WARNINGS, cognitive-complexity, file-size, cyclomatic
//     complexity, dead-code, type-coverage, compression-budget, openapi-coverage,
//     workflow-lint/zizmor, codeql-ratchet) → ratchet drift accrued across the
//     cycle is NOT a contributor's fault; it is reported and rebaselined by the
//     maintainer at release. Drift NEVER changes the exit code, so wiring this as
//     a check can never block anyone on drift.
//
// COMPLETENESS: this mirrors the FULL release-PR gate set (quality-gate +
// quality-extended + docs-sync-strict + integration), not a subset — and reports
// EVERY red in one pass (the report is collected, not fail-fast), so the release
// PR is green on its first CI run instead of revealing reds in ~40-min layers. The
// only release-PR gates it cannot reproduce locally are GitHub-side CodeQL semantic
// analysis and SonarQube/SonarCloud (external services).
//
// This script DIAGNOSES + REPORTS only (no auto-fix). The fix-to-green
// orchestration lives in the /green-prs + review-prs flows that call it.
//
// Usage:
//   node scripts/quality/validate-release-green.mjs [--json] [--with-build] [--quick]
//     --json        emit machine-readable JSON to stdout (report goes to stderr)
//     --with-build  also run check:pack-artifact (needs a dist/ build — slow)
//     --quick       skip the slow unit + vitest + integration suites (drift + fast
//                   gates only)
