"""
Shared helpers for repo integration tests.

Intent:
- Default to **real AWS S3** when credentials + bucket are provided (internal env).
- Fall back to **MinIO (S3-compatible)** for local dev (no AWS creds needed).

These helpers return connection payloads compatible with the existing `aws-s3` MCP connector.
