Storage library; signed_url share; zero-downtime deploys

September 5, 2026

What shipped.

• Drive is now Storage. Console /app/storage is a folder browser (drag-drop, multi-file). MCP storage_publish returns a presigned signed_url for agents; humans still get durable /d/{token}.
• Files stays the document layer — versioned HTML / Markdown / diagrams on /app/files and /s/{slug}. Storage is any file type in the Railway bucket.
• Root railway.toml now has healthcheckPath=/health. The server /data volume is gone. Railway will not overlap two deploys on the same volume, which was 502ing cutovers.
