Looped systems · AirTight
The loop that never leaves the building.
AirTight is Perslis running end to end on your own machine — build, review, and proof — with no API call, no network, and no data leaving. It is the mode for work that legally or physically cannot go to a cloud.
Most AI tools assume the cloud. AirTight assumes the opposite: that the most valuable data — patient records, privileged legal material, classified systems, unreleased source — is exactly the data that must never leave your control. In AirTight mode the whole loop runs locally: a local model (through Ollama) builds the work, a symbolic engine (Jeeves) checks it with no LLM at all, and the record of what happened is written to disk you own. Nothing is sent anywhere. It works on a laptop with the Wi-Fi off.
What "airtight" means, exactly
- No API: the model weights run on your hardware, not a vendor's.
- No network: the loop makes zero outbound calls — provable by running it offline.
- No third party: your prompt, the answer, and the evidence never touch someone else's server.
- Opt-in cloud: the frontier is available per task, never assumed. AirTight is the default for anything you mark sensitive.
The airtight loop
It is the same build → review → verify loop the rest of Perslis runs — only the participants change to ones that stay home:
Build — local model
A local LLM (Qwen, Llama-class) drafts the work through Ollama. Smaller than the frontier, but private and free, and often all a task needs.
Check — Jeeves
The symbolic engine tests the reasoning against known rules and facts. Deterministic, offline, no model to call — an airtight second opinion.
Record — your disk
The plan, the steps, and the verification receipt are written locally, so you keep a full, auditable trail without shipping a byte.
Who it is for
Anyone whose data has a legal or physical reason to stay put: healthcare and legal practices under privacy duties, defence and critical-infrastructure work on air-gapped networks, companies protecting unreleased IP, and anyone who simply refuses to hand their work to a third party. AirTight is how Perslis is useful to them without asking them to compromise.
