Go is the default for new module code; the holder is one binary like the licence manager, serving
the seat's verbs over the SDK and running the nights beside them. Same behaviour and tests.
ADR 0214 / to-be 43. restic keeps one repository per machine and takes a nightly snapshot per
module — 14 daily, 8 weekly, 6 monthly — and restores beside the live data, never over it. postgres,
mssql and mongodb contribute a consistent dump; minio, influxdb, the vault, mailu, gitea and
nextcloud the directories that hold their data.
