<NodeMode mode="any" />

Records an anomaly when traversal reaches it. Passes the input value
through unchanged so the node can sit inline between two other nodes.

### Inputs

* **Data in** — value to pass through. Optionally captured into the
  anomaly's params under *Param key* so consumers can report it back.
* **Entity ID** — optional Twine-internal UUID of the entity the
  anomaly is about. Populates the row's `entity_id` column for the
  auto-resolve sweep and rich entity rendering in the UI.
* **External ID** — optional source-system identifier for the entity.
  Always populate this in `convert_from_system` flows: at that
  pipeline stage, the only id available is the remote one.

### Outputs

* **Result** — the input value, unchanged.

### Schema

* **Code** — short stable identifier (e.g. `missing_phone`).
* **Severity** — `info` / `warning` / `critical`. Influences how
  consumers triage and surface the anomaly.
* **Message** — human-readable description shown to the customer. In flow
  mode, `{assign}` / `{assign.nested.path}` tokens are interpolated from the
  run's assigns when the anomaly is recorded (same syntax as Flow Log).
* **Param key** — optional. In data mode, captures the inbound value under
  this key so the message template can reference it. In flow mode it names an
  **assign** to capture (resolved like a `{token}`, nested paths allowed),
  recorded in the anomaly's captured params — the input port carries no
  meaningful value in a flow, so the assign is the source.
* **System integration** — flow mode only: the tenant integration the
  persisted anomaly row is scoped to. Required when the node runs in a
  flow; ignored in data (property-mapping) mode.
