Notes on building Transit AI

Engineering notes, security thinking, release announcements, and the occasional thing we got wrong.

• We added a local terminal and SFTP. The AI still can't touch either.

  Transit v5 adds a local terminal, SFTP file transfer, and split-screen tiling. None of them widened what the investigation-only AI can reach, and the build is what enforces that.

• Why We Made the AI Run Local — and What Never Leaves Your Network

  Run the Transit agent on models you host — Ollama or your own OpenAI-compatible endpoint. Nothing conversational leaves your network, :cloud models are hidden, every guardrail stays identical.

• gNMI Won Telemetry. RESTCONF Still Deserves QUERY.

  RFC 10008 gave HTTP a safe, cacheable method with a body. A sketch of a RESTCONF QUERY binding — server-side selection, readable filters, cacheable reads — and why gNMI shops shouldn't care.

• Why IPv8 Will Never Work (and the Ideas Worth Stealing)

  The IPv8 follow-up: the community verdict, why the Zone Server concentrates too much risk to deploy, how the backward-compatibility story contradicts itself, and the ideas still worth stealing.

• IPv8: The Draft of a New Internet

  IPv8 proposes 64-bit ASN-prefixed addresses, IPv4 as a proper subset, and a Zone Server that absorbs DHCP, DNS, auth, and egress control. We read draft-thain-ipv8-00 — and did the Zone Server math.

• Why Every Network Ticket Lands on the Same Desk

  The junior can't practice, the senior can't delegate, the manager can't de-risk. Three network careers stuck on one design flaw: investigation requires write access.

• How to Find Which Switch Port a Device Is Plugged Into (the MAC Hunt)

  The manual MAC-hunt playbook — ARP to MAC table to LLDP, switch by switch — and how Transit AI's investigation-only agent runs the same trace in about a minute without changing a thing.

• Hardware People Are Allowed to Use AI

  Software chases the newest stack; infrastructure won't touch AI in production. That's a skill issue, not a hardware limit — here's how to make AI a force multiplier without the slop.

• Why We Made the AI Investigation-Only — and How We Enforce It

  Transit AI's network agent is investigation-only by architecture, not policy — enforced by four abilities, per-vendor allowlists, a build check, and your click.

• Anatomy of the TanStack supply-chain attack

  A worm hijacked TanStack's own CI and shipped 42 poisoned npm packages — no maintainer phished, no credential stolen. What to look for, and what to do.
