koriweb d8a80f6272 chore(wiki): dangling 링크 canonical 정규화 (768파일/1200건)

이름만 다른(표기 변형) [[위키링크]]를 대상 문서의 canonical 제목으로 치환해
끊겼던 1,200개 링크를 연결. 제목/파일명 정규화 일치만 적용하고 별칭 매칭은
과병합 위험으로 제외(애매성 가드). 원본은 _link_reconcile_backup/ 에 백업.
도구: Datacollect/scripts/link_reconcile_apply.mjs

Quality Gates

매 한 줄

"매 fail-fast checkpoint between commit and production". 1990s ISO 9000 의 stage-gate 의 software 의 응용. 매 modern CI/CD 에서 매 PR merge / deploy 의 block 하는 자동 check 의 set. 매 SonarQube 가 popularized — coverage + bugs + smells + security 의 threshold-based gate.

매 핵심

매 layer (commit → prod)

Pre-commit (local): format, lint, secrets scan.
PR gate: build, unit test, coverage, security scan, type check.
Merge gate: full integration test, mutation test (선택).
Pre-deploy: smoke test, perf budget, manual approval.
Post-deploy: canary metrics, error rate, SLO.

매 dimensions

Correctness: tests pass, type-check.
Coverage: line / branch / mutation %.
Style: lint, format.
Security: SAST, dep scan, secret scan, license.
Performance: benchmark regression, bundle size.
Docs: changelog, ADR for breaking change.

매 응용

Open-source PR review automation.
Regulated industry (SOX, HIPAA) audit trail.
Monorepo platform consistency.
AI-generated code 의 sanity gate.
Deploy promotion.

💻 패턴

Pre-commit (local)

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/astral-sh/ruff-pre-commit
    rev: v0.8.0
    hooks: [{id: ruff}, {id: ruff-format}]
  - repo: https://github.com/gitleaks/gitleaks
    rev: v8.21.0
    hooks: [{id: gitleaks}]
  - repo: https://github.com/pre-commit/mirrors-mypy
    rev: v1.13.0
    hooks: [{id: mypy}]

GitHub Actions PR gate

name: PR Gate
on: [pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: astral-sh/setup-uv@v3
      - run: uv sync
      - run: uv run pytest --cov=src --cov-report=xml --cov-fail-under=80
      - run: uv run ruff check .
      - run: uv run mypy src
      - uses: codecov/codecov-action@v5

      - uses: github/codeql-action/init@v3
      - uses: github/codeql-action/analyze@v3

SonarQube quality gate (Sonar Way)

- Coverage on new code ≥ 80%
- Duplicated lines on new code ≤ 3%
- Maintainability rating on new code = A
- Reliability rating on new code = A
- Security rating on new code = A
- Security hotspots reviewed = 100%

Branch protection (GitHub API)

gh api -X PUT "repos/{owner}/{repo}/branches/main/protection" \
  -F required_status_checks[strict]=true \
  -F required_status_checks[contexts][]=test \
  -F required_status_checks[contexts][]=security \
  -F required_pull_request_reviews[required_approving_review_count]=2 \
  -F enforce_admins=true

Performance budget gate

- name: Bundle size check
  run: |
    npm run build
    SIZE=$(stat -c%s dist/main.js)
    if [ $SIZE -gt 250000 ]; then
      echo "Bundle exceeds 250KB budget: $SIZE"
      exit 1
    fi

Mutation testing gate (Stryker / mutmut)

- run: uv run mutmut run
- run: |
    SCORE=$(uv run mutmut results | grep -oP 'killed.*\K\d+')
    if [ $SCORE -lt 70 ]; then exit 1; fi

Canary deploy gate

- name: Canary 5%
  run: kubectl set image deploy/app app=app:${{ github.sha }} --namespace=canary
- name: Wait + check SLO
  run: |
    sleep 600
    ERROR_RATE=$(prom_query 'rate(http_5xx[10m])')
    if (( $(echo "$ERROR_RATE > 0.01" | bc -l) )); then
      kubectl rollout undo deploy/app --namespace=canary
      exit 1
    fi

AI-generated code gate (2026)

- name: AI code review
  uses: anthropics/claude-code-action@v1
  with:
    api-key: ${{ secrets.ANTHROPIC_API_KEY }}
    review-mode: security-and-quality
    fail-on: high

Required-files / docs gate

# require ADR for breaking change
if git log -1 --pretty=%B | grep -qi 'BREAKING'; then
  git diff --name-only HEAD~1 | grep -q '^docs/adr/' || {
    echo "Breaking change requires ADR"; exit 1; }
fi

매 결정 기준

상황	Gate set
Solo prototype	Pre-commit only
Team project	+ PR test/lint/security
Production SaaS	+ coverage + perf + canary
Regulated (HIPAA/SOX)	+ SAST + DAST + audit log
Open source	+ DCO + license + dep review

기본값: pre-commit + PR test/lint/type/coverage 80% + Trivy + branch protection.

🤖 LLM 활용

언제: 매 gate config draft, 매 SonarQube 의 ruleset 의 explain, 매 CI YAML 의 generate. 언제 X: 매 production gate threshold (coverage %, SLO %) — 매 team-context 결정.

❌ 안티패턴

Coverage as only gate: 매 100% coverage + 매 0 assertion 가능. 매 mutation test 의 augment.
Slow gates (>10min): 매 dev velocity kill. 매 parallelize / shard.
Flaky gates: 매 false positive 의 retry-bypass culture. 매 quarantine + fix.
Legacy code 의 same threshold: 매 new-code only 의 ratchet.
Gates without humans: 매 automation alone 의 architectural smell 의 miss.
Bypass culture: --no-verify / admin merge — 매 audit log + alert.

🧪 검증 / 중복

Verified (SonarQube docs, GitHub branch protection API, ISO 9000 stage-gate origin).
신뢰도 A.
