🛡️ Sentinel: [CRITICAL] Fix hardcoded admin password

[seonghobae]

🚨 Severity: CRITICAL

💡 Vulnerability: Hardcoded Secrets

A plaintext, hardcoded administrator password (og9oRajx7h88v1RIj3eDgdrh9jgLYVV3) was discovered directly in the source code (packages/web/src/lib/server/admin-auth.ts).

🎯 Impact

Anyone with read access to the source repository or access to the compiled artifacts could trivially extract this master password and gain full administrative access to the application, completely bypassing intended security controls.

🔧 Fix

1. Removed the hardcoded string from packages/web/src/lib/server/admin-auth.ts.
2. Updated the central Zod schema in packages/web/src/lib/server/env.ts to require ADMIN_PASSWORD with a minimum length of 8 characters.
3. Updated packages/web/src/lib/server/admin-auth.ts to read from env.ADMIN_PASSWORD. The existing export was preserved (export const ADMIN_PASSWORD = env.ADMIN_PASSWORD) to avoid breaking dependent imports.
4. Added a placeholder ADMIN_PASSWORD=change-me-in-production to packages/web/.env.example.
5. Injected a dummy value into the .github/workflows/ci.yml build step to prevent the Next.js build from failing during schema validation in CI.
6. Logged this critical finding in .jules/sentinel.md to establish a persistent security baseline against hardcoded credentials.

✅ Verification

1. pnpm install
2. pnpm exec prisma generate
3. cd packages/shared && pnpm build
4. pnpm lint and pnpm --filter @argos/web test and pnpm build pass successfully locally, confirming that the new required environment variable functions correctly without breaking tests or the production build.

최신 upstream/main 기준으로 이 PR 브랜치(sentinel-fix-hardcoded-admin-password-15712461706967457741)는 97개 파일의 stale diff를 포함합니다. 특히 .claude agent/skill 파일 삭제와 오래된 lockfile/env/code 변경이 섞여 있어 그대로 유지하거나 upstream에 올리면 이미 반영된 변경을 되돌릴 위험이 큽니다.

현재 큐는 upstream #30 → upstream #21 순서로 정리 중입니다. 이 PR의 아이디어가 여전히 필요하면 최신 upstream/main에서 단일 목적 브랜치로 깨끗하게 다시 추출하겠습니다. stale PR로 닫습니다.
