Add-on: Object Storage (MinIO/S3)

Use this skill when the project needs durable storage for:

• original uploaded PDFs
• derived markdown/page artifacts
• JSONL artifacts
• report exports

Local dev uses MinIO; production can switch to AWS S3 (or any S3-compatible store) without changing calling code.

Inputs

Collect:

• S3_BUCKET: default documents.
• S3_REGION: default us-east-1 (ignored by MinIO but kept for portability).
• S3_ENDPOINT_URL: for MinIO, typically http://minio:9000 inside compose.
