graph getStarterPack/getStarterPacks do not have defined record properties - missing definition?

[blowdart]

getStarterPack/ getStarterPacks have a record type of unknown

API calls show it's defined, e.g.

{
    "$type":"app.bsky.graph.starterpack",
    "createdAt":"2024-08-27T10:53:50.048Z",
    "description":"A list of folks and groups involved in information security.",
    "feeds":[],
    "list":"at://did:plc:hfgp6pj3akhqxntgqwramlbg/app.bsky.graph.list/3l2p2bbpapo2a",
    "name":"Infosec Starter Kit",
    "updatedAt":"2024-08-27T11:05:47.022Z"
}

Presumably from https://github.com/bluesky-social/atproto/blob/main/packages/bsky/src/hydration/hydrator.ts#L679 feeds is an array of aturis?

Is the lexicon missing a definition for starterpack?
