Overview

Implement storage operations for metadata and blob handling in R2, building on the R2 client wrapper to provide high-level storage functionality for GhostPaste.

Tasks

• Implement metadata upload/download (JSON) using R2 API
• Implement blob upload/download (binary) using R2 API
• Implement streaming for large files
• Add retry logic for transient failures
• Create storage utility functions
• Write integration tests with miniflare

Technical Requirements

• JSON metadata stored with content-type application/json
• Binary blobs stored with content-type application/octet-stream
• Streaming support for files up to 5MB
• Exponential backoff for retries
• Consistent key naming scheme

Acceptance Criteria

• Can store and retrieve JSON metadata
• Can store and retrieve binary blobs
• Streaming works for files up to 5MB
• Handles network errors gracefully
• Integration tests pass with miniflare
• Retry logic handles transient failures

Dependencies

• feat: implement R2 storage foundation #103 (R2 Storage Foundation)
