여기부터 보세요

• .github/ISSUE_TEMPLATE/bug_report.yml collects OS, Node.js version, install method, chosen runtime, gh-symphony doctor --json, and gh-symphony doctor --bundle attachment context.
• .github/ISSUE_TEMPLATE/feature_request.yml follows PROJECT_MANAGE.md sections: Background, Proposed Changes, Affected Files, plus optional spec/reference sections.
• .github/PULL_REQUEST_TEMPLATE.md reflects CONTRIBUTING.md expectations for linked issues, behavior/operational impact, validation commands, Changesets, follow-up work, and security hygiene.

위험 & 롤백

• Risk is limited to GitHub UI metadata. It does not change runtime, package code, workflows, or the upstream Symphony spec.
• Rollback is deleting the four added .github template files.

Watchdog review result: approve.

Evidence bundle: https://evidence-browser.dev0.daniworks.kr/w/github-symphony/b/20260702-0449-project14-pr423-attempt1

Scope reviewed:

• Added GitHub issue templates and PR template only.
• Verified templates capture environment, gh-symphony doctor --json, and gh-symphony doctor --bundle diagnostics requested by #391.

Smoke tests run:

• git diff --check origin/main...HEAD — passed
• pnpm exec prettier --check on changed template files — passed
• YAML parse/basic GitHub issue-form structural validation — passed

Blocking findings: none.

Note: Claude Code review was attempted in read/test-only mode but failed authentication (401), so this approval is based on watchdog inspection plus the smoke tests above.
