Publishing and Storage

For deploying content-addressed storage using CIDs, this repository includes tools for uploading to Cloudflare R2 (S3-compatible storage).

R2 Upload Script

The .github/scripts/r2_upload.py script uploads files to R2 with metadata-based CID verification:

Stores the CID in object metadata (Metadata={'cid': cid})
Verifies objects using head_object() to check metadata (fast, no download)
Falls back to downloading and computing CID if metadata is missing
Does not rely on ETag (which cannot be set and is unreliable for multipart uploads)

See .github/scripts/README.md for detailed usage, examples, and a Cloudflare Worker snippet showing how to override the ETag header for clients.
