Add IPFS invoice metadata pinning with CID verification #848
Description
Overview
Allow invoice creators to attach structured metadata stored on IPFS. The CID is stored in the contract memo field. The SDK should pin metadata to IPFS, verify the CID matches the content, and enrich invoice reads with the resolved metadata.
Requirements
- pinInvoiceMetadata(metadata: InvoiceMetadata): Promise — pins JSON to IPFS, returns CID
- InvoiceMetadata { title, description, lineItems: LineItem[], attachmentCIDs: string[] }
- verifyCID(cid, content): Promise — fetches and checks content hash
- enrichInvoice(invoiceId): Promise — merges on-chain + IPFS data
- Support IPFS HTTP gateway and kubo RPC backends (configurable)
- Tests with mock IPFS server; CID mismatch handled gracefully
Acceptance Criteria
- Metadata pinned and CID returned
- CID verification detects tampering
- enrichInvoice merges data correctly
- Both gateway and kubo backends work
- npm test passes with zero failures
- TypeScript compiles with zero errors
- ESLint passes with zero errors
Definition of Done
All CI checks must pass before the PR is reviewed.
