Tells the story of moving ArcBox from Apple's Virtualization.framework to a custom VMM on Hypervisor.framework: motivation, first-boot sprint, representative bugs, benchmark numbers, and honest gaps. Sets up the "Leaving Rosetta behind" post as the follow-up.
The SIGILL surfaced during FEX testing and was caused by our FEX binary being built on an SVE-capable CI host, not by a macOS virtualization layer bug. Belongs in the FEX post's build-target story, not here.
The "Try it" block invented `arcbox start`; the real CLI is `abctl`, and the runtime needs `abctl docker enable` to point the Docker CLI at the ArcBox socket. Switch the "what we left on the table" line from the `ARCBOX_VM_BACKEND` env var (first-boot only) to `abctl system backend hv` (the runtime command).
Drop the "four issues opened, Priority 1, Done" ticketing metaphor for plain language, and replace the internal Linear project link with the public GitHub repo so outside readers can actually follow the work.
…has no cover The featured hero rendered featured.data.cover with a non-null assertion, so any coverless newest post crashed the /blog prerender.
…on, tidy frontmatter - The three-way review landed three days into the sprint, not two, and about half of its findings closed within days, not most. - Note the iperf3 numbers are host-to-guest. - Rename the CLI latency row to 'after idle' and mark the VZ cell as not measured instead of opaque. - uname -m matches the shown output; uname -a prints a full line. - Drop the 'featured' frontmatter field: it is not in the blog schema and nothing reads it.

Adds the new engineering blog post explaining ArcBox's move from Apple's Virtualization.framework to a custom VMM on Hypervisor.framework, plus the UI fallback needed for posts without a bespoke cover image.
