Record a decision about a link, replacing any previous decision of the same kind for that pair.

POST

/api/v1/topology/link-overrides

curl --request POST \
  --url https://example.com/api/v1/topology/link-overrides \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "a_node": "2489E9AD-2EE2-8E00-8EC9-32D5F69181C0", "action": "pin", "b_node": "2489E9AD-2EE2-8E00-8EC9-32D5F69181C0", "direction": "a_parent", "note": "example" }'

The decision takes effect on the next derivation cycle. A pinned link is re-emitted by every run, so it never expires the way an unobserved derived link does.

Request Body^required

Media typeapplication/json

A decision to record about one link.

object

a_node

required

One endpoint. Order is not significant — the pair is canonicalized before storing, and a direction is re-expressed to match.

string format: uuid

action

required

pin, hide or direction.

string

Allowed values: pin hide direction

b_node

required

The other endpoint.

string format: uuid

direction

One of:

null

null

string

Which endpoint is upstream. Required when action is direction, rejected otherwise.

string

Allowed values: a_parent b_parent

note

Free-text note for whoever reads this decision later.

string | null

200

The decision was recorded

Media typeapplication/json

The id of a freshly created resource — the whole body of a 201.

Deliberately one shape for every creator. The json!({"id": …}) literal it replaces was written out per handler, which is how {"id": …} and {"node_id": …} both ended up in this API for the same idea; a client then needs to know which creator it called to read the id back.

The two endpoints are the same node, or direction disagrees with action

The ADR-019 envelope every failure renders as. pub(crate) and schema-bearing so the OpenAPI document can name one error shape for every endpoint (ADR-035) instead of leaving 4xx/5xx bodies undescribed — a client that has to guess the failure shape ends up parsing the success shape and reading undefined.

object

error

required

object

code

required

Stable machine-readable code. Clients branch on this, never on the message.

string

message

required

Operator-facing sentence. Safe to display; never carries an internal error’s own text.

string

Example^generated

{
  "error": {
    "code": "example",
    "message": "example"
  }
