Session architecture

Make every saved session explain itself.

A session baseline ties a human-readable name to a destination role, authentication decision, expected host key, gateway path, and operator owner.

Blueprint model of workstation, identity checkpoint, gateway, and destination
IDENTITY · VERIFY · ROUTE · ARRIVEReference architecture
Identity
Username source, approved key location, agent behavior, and credential owner.
Destination
Canonical host, role, environment, port, and maintenance context.
Trust check
Expected fingerprint source and an escalation route for a changed host key.
Experience
Terminal mode, keepalive, compression, SFTP browser, and optional X11 intent.
Workshop output

One decision log, four artifacts.

  1. Session naming and folder convention.
  2. Authentication and host-verification notes.
  3. Operator test script with expected outcomes.
  4. Exception list for gateway, transfer, or display routes.

Route steps

  1. Inventory

    Collect current sessions and destination roles.

  2. Normalize

    Separate shared conventions from personal preference.

  3. Test

    Run first connection, reconnect, and exception cases.

  4. Hand off

    Publish a bounded operator packet.

Need a gateway in the route?

Map the session first, then place the jump host and tunnel purpose explicitly.
