System settings

Studio → Security → System settings (admin only).

Surface

• Quick / Advanced tier filter (Basic / Advanced)
• Section tabs: network, database, runtime, historian, identity, backup, license, opcua, webhook, observability, deploy, other
• Each row: dotted id + VION_* env name; secrets masked
• Env-sourced rows show a lock badge
• Apply → save + possible supervised restart

Schema: GET /api/v1/system/settings and during setup GET /api/v1/setup/schema (crates/server-config schema_json()).

Steps not shown in the UI

Registry steps admin and commands are not Studio tabs. Set them via first-run, vion.toml, or process env:

• VION_BOOTSTRAP_ADMIN_USERNAME / PASSWORD
• VION_COMMAND_TOKEN, VION_COMMAND_STEP_UP, VION_COMMAND_REASON_REQUIRED

Studio relationship

GET /api/v1/system/client-config returns runtimeBase; Studio resolves the runtime per project via GET /api/v1/runtime/endpoint and does not read that field.
