# s3-storage — Architecture

Shared S3-compatible storage client for MNW and MT.

## What It Does

Thin wrapper around `aws-sdk-s3` providing upload, download, delete, presigned URLs, CORS configuration, and connectivity checks. Extracted from MNW to avoid duplicating S3 initialization across services.

## Consumers

| Service | Usage |
|---------|-------|
| MNW | File uploads, download delivery, presigned upload URLs |
| MT | Forum image/file uploads |

## Key Types

- `S3Config` — endpoint, bucket, credentials, region
- `S3Client` — wraps `aws_sdk_s3::Client` with bucket-scoped operations

## Key Paths

| What | Where |
|------|-------|
| All code | `src/lib.rs` (single file, ~287 lines) |
