Attach a data object to a node via the content-addressed store

Serializes data through the project's CAS store and records a data_ref = "cas:sha256:..." param on the node, so the stan_data executor can fetch it at run time without an embedded code channel. Existing params are preserved (merged, not replaced). The data object must be serializable via base::saveRDS().

Usage

bg_set_node_data(project, node_id, data)

Arguments

project

A bg_handle.

node_id

The node to attach data to (typically a stan_data node).

data

An R object to attach.

Value

The node ID, invisibly.
