Updating an air-gapped appliance
How signed release bundles let a disconnected system stay current without ever opening a path to the outside.

[TBD: draft] — This is a placeholder. The outline below records the intended structure. No claim here has been reviewed for publication.
What this note will cover
The standard objection to air-gapped deployment is maintenance: if the system cannot reach the internet, how does it stay current? The usual answer — open a connection briefly — gives up the property the gap was there to provide.
This note will describe the release bundle model: a complete, versioned, signed set of software and model artifacts that crosses the gap on physical media and is verified before anything is applied.
Intended structure
- Why "temporarily connect it" is not a maintenance strategy
- What a release bundle contains and how it is signed
- Verification at the appliance, and what happens when verification fails
- Recording what was installed, and why that record matters later
Status
[TBD: draft] — copy pending review.
