    If they built a WASM runtime, why do they keep on talking about using wasmtime, which is a WASM runtime.

      Yeah they phrase it more honestly on the actual GitHub repo as a WASM execution platform which makes more sense

    I appreciate the write up.

    It comes off very much as a summary of days of vibe-coding from the AI itself, but it's still nice to see the condensed decisions, approach and frankly the whole concept of embedding a wasm runtime.

    I would treat bwrap processes as single-use across tenants, since host-side state (allocator, FDs, namespace bits) accumulates and you can not really prove it clean.

    “I got an LLM to write a summary of the work it did while I occasionally checked in on Cursor.”

    I’m getting so tired of these posts. Why waste our time?
