Archetype A - historical immutable-release agent design

Status: Fictional historical acceptance-design lesson, not a runnable workload or current architecture. The legacy promotion commands and per-profile gateway files were retired.

This archetype contrasted an exact-commit Python release selected by a current symlink with a package-version release in Archetype B. Its lesson was to record source identity, capture the previous target before promotion, re-derive running state, and exercise rollback. The symlink and gateway-profile layout was an application-level design, not a security isolation proof. No command in this page should be used as a live deployment runbook.

The current operator-reported narrative instead groups individual OpenShell agent sandboxes in realms under an operator-core VM. Realms group workloads; no inter-realm isolation measurement is implied.
