  Endpoint returns 401 with INTERNAL_EMAIL_KEY pulled via 'vercel env pull --environment=production'. Verified Vercel runtime logs (dpl_3wt5WbRr1aRgEvYY2iRcKnsP4UXu, 2 POSTs both 401). Key=66 chars head 'eeae' — CLI appends literal backslash-n suffix; even trimmed to 64 still 401. Workaround 2026-05-18: one-off node script importing nodemailer w/ SMTP_USER/SMTP_PASS (thread coder-mars-cc-31822 + pm-mars-cc-31835, c38be946 messageId). Next probe per audit-mars-cc-31832: redeploy first, then deeper bundle/env-drift investigation if 401 persists.

  Root cause: original env var INTERNAL_EMAIL_KEY had type='sensitive' (Vercel's encrypted-not-exfiltratable storage) — vercel env pull returns a placeholder/different value for sensitive vars, so locally pulled key never matched what the function received at runtime. Fix: DELETE the sensitive entry, POST fresh with type='encrypted' via REST API, redeploy. Probe POST /api/internal/send-email now returns 200 OK eventId ae44a4d9-a118-4886-90b6-c4c9063bf382 against dpl_3ip6vQDJmJDVpiasEjKcytvRTJZL. Mars feedback memory feedback_vercel_mcp_no_dashboard.md to update: type matters (sensitive vs encrypted) for vercel env pull plaintext access.
