fix(governance): restack fatal UTF-8 production evidence on 293e338 main

[seonghobae]

Purpose

Continue the bounded production-environment evidence UTF-8 hardening from #345 on current protected main 293e3380cf26ef399068245ad6c82929d86f95fa, without force-pushing, stale ancestry, or overwriting the integrated #346 coverage slice.

Test-first RED

• protected base at construction: 293e3380cf26ef399068245ad6c82929d86f95fa;
• stable source fix(governance): restack fatal UTF-8 production evidence on current main #345 exact head at construction: 105f69ff41edb4f6a1b1a4d0f12cb3a41edb4e1e;
• RED exact head: 3d29ef9d39b51de1e7892a1d3022ecdf72a56d05;
• RED changes only test/production-environment-governance-utf8.test.ts, exact source blob 8ab66b0a6fc51708cdd8292513f3d1eed96270c3.

A fresh comparison from #345's construction base to current protected main showed only #346's src/index.ts / coverage-contract delta, with no overlap on the production-environment audit or focused UTF-8 test. The focused test requires a fatal UTF-8 decoder export that current protected production code does not provide, so this head is intentionally RED.

Planned narrow GREEN

After the RED is observed on this exact head, change only scripts/production-environment-governance-audit.mjs to the reviewed #345 implementation: keep bounded gh stdout/stderr as raw bytes, fatal-decode UTF-8 before JSON interpretation, preserve shell-free execution, explicit child environment, 2 MiB output ceiling, token redaction, API-version binding, and existing policy semantics.

No predecessor CI/review/scanner/coverage/model/production/release/deployment evidence transfers. Pending/queued/skipped/absent/neutral/failed/cancelled/stale/predecessor/status-only/model-only/rate-limited evidence is non-passing. Keep Draft through RED -> GREEN, then require fresh terminal-success application ci, reviewer-ci, protected-base central Security Scan, configured exact 100% owned-production statement/branch/function/line coverage with realistic tests, and zero valid unresolved findings.

This does not claim that a live production environment exists or passes. It does not modify central .github, naruon, contextual-orchestrator, live policy, reviewer authority, secrets, releases, deployments, licensing, or other repositories.

📝 Walkthrough

Walkthrough

GitHub CLI 출력을 원시 바이트로 처리하고 fatal UTF-8로 디코딩합니다. 감사 실행은 환경과 콜백을 주입받습니다. 성공 및 실패 보고서, 오류 진단, 저장 경로와 CLI 진입점을 검증하는 테스트를 추가합니다.

GitHub CLI 출력 및 실행 제어

Layer / File(s)	Summary
출력 디코딩과 오류 상세 처리 scripts/production-environment-governance-audit.mjs, test/production-environment-governance-utf8.test.ts	decodeGhOutput가 원시 출력을 fatal UTF-8로 디코딩합니다. runGh는 비정상 종료 시 stderr를 우선 사용하고, 없으면 stdout과 종료 상태를 사용합니다.
감사 실행 의존성 주입 scripts/production-environment-governance-audit.mjs, test/production-environment-governance-utf8.test.ts	main과 환경 수집이 환경, CLI 실행 함수, 로그 함수, 종료 코드 설정 함수를 주입받습니다. 보고서와 요약은 전달된 환경의 경로를 사용합니다.
감사 결과 및 진입점 검증 test/production-environment-governance-utf8.test.ts, test/production-environment-governance.test.ts, vitest.config.ts	성공 및 실패 보고서, 입력 정규화, 오류 진단 보존, 잘못된 저장소의 조기 실패, CLI 진입점, 제한된 subprocess 환경과 커버리지 대상을 검증합니다.
