Twin node

The Twin (twin) node reads a digital twin and its assigned controller policy and exposes them as structured outputs. Use it upstream of Fuzzy Matcher so voice pipelines know which command strings are valid for that robot, and to surface controller identity/mode to downstream nodes.

Palette category: Data Sources. Runs on cloud and edge (edge workers resolve the policy via the Cyberwave API).

Inspector

Digital Twin — combobox selector.
twin_uuid is stored in node parameters, not the generic input-mapping row.

Policy resolution

The node resolves the active policy from:

Twin controller_policy FK, or
twin.metadata.controller_policy_uuid

If neither is set, execution fails with a clear error.

Outputs

Field	Type	Description
`name`	string	Twin display name
`asset`	string	Asset slug from policy metadata (or first linked asset)
`device`	string	Input device from policy metadata (e.g. `keyboard`)
`control_actuations`	array	Locomotion actuation slugs from `metadata.keyboard_bindings` (`move_forward`, `turn_left`, …)
`control_labels`	array	Human-readable labels from all keyboard bindings
`controller_name`	string	`metadata.controller_name` on the assigned controller policy
`controller_type`	string	`metadata.controller_type` on the assigned controller policy
`control_mode`	string	`metadata.control_mode` on the assigned controller policy

control_actuations only includes locomotion slugs (WASD-style). Non-locomotion bindings (lights, camera, take_photo) appear in control_labels but not in control_actuations.

Fuzzy Matcher wiring

Twin output	Fuzzy Matcher input	Notes
`control_actuations`	`candidates`	Match STT against actuation slugs (`move_forward`)
`control_labels`	`candidates`	Match STT against spoken labels (`Move Forward`)

Execution targets

Target	Notes
Cloud	`WorkflowUtils._execute_twin_node` — reads twin + policy from Postgres
Edge	Code emitter calls `client.twins.get` + controller-policies API
