Private blob storage now GA with OIDC token auth and scoped signed URLs—replaces static credential management for sensitive file access.
Summary
Eliminates long-lived credentials from environment variables and enables temporary, operation-scoped access tokens for client-side uploads without exposing server credentials. Critical for handling user data, invoices, and agent memory with fine-grained access control.

Implementation verdict
Ready now. Drop-in API change (`access: 'private'` parameter). Requires Vercel runtime for OIDC auto-rotation; CLI supports OIDC for local workflows. Signed URLs replace presigned S3 patterns. Worth adopting immediately if storing sensitive files—reduces credential sprawl and audit surface.
