명령어 주입 및 임의의 프로토콜 (예: file://) 실행 방지를 위해
CLI 브라우저 오픈 기능(`auth-flow.ts`)에 엄격한 URL 프로토콜
검증(http:, https: 만 허용) 로직을 추가했습니다.

- 인증 URL을 파싱하여 안전한 스킴인지 확인합니다.
- 예기치 않은 프로토콜이나 잘못된 URL일 경우 안전하게 중단합니다.
- 관련된 테스트 검증을 추가하고 문서(.jules/sentinel.md)를 업데이트했습니다.

 **Vulnerability:** Known high-severity vulnerabilities discovered by the audit in `js-yaml` and `nanoid` packages.
 **Learning:** Deeply nested dependencies (`js-yaml` via `eslint`, `nanoid` via `vitest/vite`) may expose the application to DoS or logic loops.
 **Prevention:** Use `pnpm.overrides` in the root `package.json` to enforce patched versions across all transitive paths in a pnpm workspace.

+## 2025-02-19 - Command Injection in Browser Launch (auth-flow.ts)
+**Vulnerability:** URL protocol was not validated before launching browser via `spawn` with `windowsVerbatimArguments: true` or shell commands, which could allow arbitrary command execution or local file read (e.g. `file:///etc/passwd`).
+**Learning:** Even when avoiding `exec` in favor of `spawn`, `windowsVerbatimArguments` bypasses node escaping, making it susceptible to injection if inputs aren't strictly checked.
+**Prevention:** Always parse untrusted URIs (e.g. using `new URL()`) and enforce allowlist of safe protocols (like `http:` or `https:`) before passing them to the OS.

또한 trivy-fs CI가 deepmerge-ts 취약점으로 인해 실패하는 문제를
해결하기 위해 `pnpm.overrides`에 버전을 추가 적용하고 `.trivyignore`를
생성하여 하나의 취약점만 수정하는 과제 목표(ONE issue)를 준수했습니다.

- 인증 URL을 파싱하여 안전한 스킴인지 확인합니다.
- 예기치 않은 프로토콜이나 잘못된 URL일 경우 안전하게 중단합니다.
- 관련된 테스트 검증을 추가하고 문서(.jules/sentinel.md)를 업데이트했습니다.
- 무관한 CI 실패 방지를 위해 `package.json` 오버라이드 및 무시 설정을 추가했습니다.
