  1. The URL Is the Hash

    Content-addressing on the wire — how the web quietly became a content-addressed store, where fingerprinted URLs and Subresource Integrity are real Merkle edges and the cache that looks most like one isn't.

  2. You Don't Want Separate Repos

    Repository topology decides whether coupled code shares one content-addressed snapshot or negotiates version strings across a registry boundary.

  3. A Little Uncertainty Buys a Lot of Space

  4. node_modules Is the Heaviest Object in the Universe
