# Nodes

## Rename

**patch** `/v1/taxonomy/nodes/{node_id}`

Renames a taxonomy node's label and records a rename event attributed to actor_id. Tenant-scoped;
returns 404 if the node does not belong to the tenant. While a tenant data purge runs for the same
tenant_id, the request is rejected with HTTP 409 (code `tenant_write_conflict`) and may be retried.

### Path Parameters

- `node_id: string`

### Body Parameters

- `actor_id: string`

- `label: string`

  New node label.

- `tenant_id: string`

### Returns

- `Node = object { id, created_at, label, 13 more }`

  A node in a taxonomy tree. Non-root nodes have a parent; leaf nodes reference the cluster they summarize.

  - `id: string`

  - `created_at: string`

  - `label: string`

  - `level: number`

    Depth in the tree; the root is level 0.

  - `node_type: "root" or "branch" or "leaf"`

    Position of a node within the taxonomy tree.

    - `"root"`

    - `"branch"`

    - `"leaf"`

  - `run_id: string`

  - `sort_order: number`

  - `updated_at: string`

  - `children: optional array of Node`

    Child nodes, present when the tree is returned hierarchically.

  - `cluster_id: optional string`

    Cluster this node summarizes; typically present on leaf nodes.

  - `description: optional string`

  - `metadata: optional map[unknown]`

  - `original_label: optional string`

    Label as originally generated, before any rename.

  - `parent_id: optional string`

    Parent node ID; absent for the root node.

  - `removed_at: optional string`

    Set when the node has been soft-removed.

  - `removed_by: optional string`

    Actor that soft-removed the node.

### Example

```http
curl http://localhost:8080/v1/taxonomy/nodes/$NODE_ID \
    -X PATCH \
    -H 'Content-Type: application/json' \
    -H "Authorization: Bearer $HUB_API_KEY" \
    -d '{
          "actor_id": "user-42",
          "label": "Authentication Problems",
          "tenant_id": "org-123"
        }'
```

## Soft Remove

**delete** `/v1/taxonomy/nodes/{node_id}`

Soft-removes a taxonomy node (sets removed_at/removed_by) and records a soft_remove event
attributed to actor_id. The node is retained for audit but excluded from tree responses.
Tenant-scoped; returns 404 if the node does not belong to the tenant. While a tenant data purge
runs for the same tenant_id, the request is rejected with HTTP 409 (code `tenant_write_conflict`).

### Path Parameters

- `node_id: string`

### Query Parameters

- `actor_id: string`

  Identifier of the actor performing the removal (recorded in the audit event).

- `tenant_id: string`

  Tenant that owns the node.

### Returns

- `Node = object { id, created_at, label, 13 more }`

  A node in a taxonomy tree. Non-root nodes have a parent; leaf nodes reference the cluster they summarize.

  - `id: string`

  - `created_at: string`

  - `label: string`

  - `level: number`

    Depth in the tree; the root is level 0.

  - `node_type: "root" or "branch" or "leaf"`

    Position of a node within the taxonomy tree.

    - `"root"`

    - `"branch"`

    - `"leaf"`

  - `run_id: string`

  - `sort_order: number`

  - `updated_at: string`

  - `children: optional array of Node`

    Child nodes, present when the tree is returned hierarchically.

  - `cluster_id: optional string`

    Cluster this node summarizes; typically present on leaf nodes.

  - `metadata: optional map[unknown]`

  - `original_label: optional string`

    Label as originally generated, before any rename.

  - `parent_id: optional string`

    Parent node ID; absent for the root node.

  - `removed_at: optional string`

    Set when the node has been soft-removed.

  - `removed_by: optional string`
