Verdict: N/A Evidence: src/lib/routers/env-vars.ts: list (with masking), set (encrypt+upsert), delete, checkRequired, validateGitHub (real API call to github.com/user), validateVercel (real API call to api.vercel.com/v2/user), validateTwilio (real API call to api.twilio.com), listVercelProjects, pushToVercel (calls pushEnvVarsToVercel with decrypted values), deployAuthToVercel (maps authConfig to env vars, pushes, triggers redeploy). Values encrypted at rest via src/lib/encryption.ts. PLATFORM_MANAGED_KEYS set controls which keys skip per-project requirement. File: N/A Recommendation: No action required. Excellent implementation with real external validations.
