Function MediaLike

Likes a media. The wire is the application profile's, not the caller's choice: it reads MobileApplicationState.mediaLikeWire (the REST api/v1/media/<id>/like/ or the graphql_www LikeMutation). The presented 451 profile declares the mutation; a 448/450-era profile declares the REST like. A profile that declares nothing is no evidence of a wire (the iOS like is not modelled), so the brick dies with MobileMediaLikeWireNotDeclaredError (a defect of the build, not a typed failure) instead of sending a request. See the field's own note and its open item.

The surface names one of the app's three like layouts — the contextual feed ('feed'), the reels viewer ('reels') and the home timeline's carousel child ('timeline'); see MediaLikeSurface. The first two have a form on both wires; the timeline's is the GraphQL build's only (the app has no REST form of it), so on a profile that declares the REST wire this brick dies with a defect that says so before any request — the library has no layout to send there, which is the library's gap, not a state a caller can answer.
