084 — Diagnosis

2026-09-22. Worse than reported. The controller's "merge" of the runtime's file merges an operator's settings into the module's content. The host then writes the result whole, so a machine's own runtime settings, including its data directory, are replaced, not added to. Measured on a lab machine: the runtime takes a new trusted-registry list on a reload, and a running container without a restart policy survives it. Decided in ADR 0102: the runtime's file is written into and the runtime reloaded. The hosts file stays a whole file, held until networking is taken.
