IPFS Deliverable Storage

[soomtochukwu]

Description
Deliverable files are currently referenced by hash only — actual file storage is not wired. Both the backend (evidence submission) and frontend (file upload) need IPFS integration.

Requirements

• Backend evidence.rs: accept file uploads; pin to IPFS via Web3.Storage or Pinata; store returned CID in evidence.file_hash
• Frontend: file picker component that uploads to backend and displays the CID
• CID must be stored in the job's on-chain metadata_hash via job_registry.submit_deliverable

Acceptance Criteria

• Uploading a file returns a valid IPFS CID (e.g. bafybei…)
• The CID is retrievable from a public IPFS gateway within 60 seconds
• Empty or oversized files (> 50 MB) are rejected before upload

@nedzoey-svg has applied to work on this issue as part of the Stellar Wave Program's 3rd wave.

I would like to work on this issue because I can implement a seamless IPFS integration that ensures deliverable files are securely stored and easily retrievable, while providing a smooth frontend and backend workflow.
I have experience with Web3.Storage and Pinata, building file upload components in React, and handling backend Rust APIs for Web3 applications. I can implement robust file validation, CID generation and storage, and ensure on-chain metadata is accurately updated. My focus is delivering a reliable, user-friendly, and production-ready solution that aligns with best practices for decentralized storage.
