Inside ZCode: Silently uploading your Git history to the cloud
ZCode, Zhipu's official AI coding desktop app, silently packages and encrypts users' entire workspaces - including full .git history, LFS asset cache, reflogs, and global app configs - then uploads them directly to Aliyun OSS, bypassing its own servers via OSS form POST. A 313MB encrypted archive (from a 345MB workspace) sat in `~/.zcode/v2/checkpoints/` with 564 failed upload retries; encryption uses AES-256-CTR with an RSA-OAEP-SHA256-wrapped key, but the server delivers the public key on the fly while the private key remains only in the cloud, making the ciphertext undecryptable by the user or client.

score 7 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
