🛡️ Sentinel: [CRITICAL] Fix missing authentication on /api/jules/sources

[parvezk]

🚨 Severity: CRITICAL
💡 Vulnerability: The /api/jules/sources endpoint lacked authentication checks, allowing unauthenticated users to trigger external API calls (realJulesPort(...).listSources()) using the server's API key. This happened because Next.js middleware in this project intentionally excludes /api paths from global authentication, requiring explicit checks for endpoints that bypass RLS (like those making external API calls).
🎯 Impact: Unauthorized access could lead to SSRF-like behavior, exhaustion of rate limits on the external API, or potential exposure of internal system configurations/data if the external call's response was leaked.
🔧 Fix: Imported currentUserId from @/lib/sessions-store and added a check at the beginning of the GET route. If currentUserId() returns a falsy value (no user), the endpoint now returns a 401 Unauthorized status with a standard error message.
✅ Verification: Verified that pnpm test in the root and pnpm lint and pnpm build in the web directory still pass. Also added a critical learning entry to .jules/sentinel.md documenting the vulnerability and how to prevent it in the future.
