Read Pipeline Node Artifact
Reads and returns the contents of a ComputedNode. For in-memory
pipelines, returns the dynamically computed value directly from the
registry. For built pipelines, reads the materialized artifact from the
latest (or specified) build log. Use which_log to read from
a specific historical build (“time travel”).
node (ComputedNode): The
ComputedNode object to read (e.g. p.node_name).
which_log (String): (Optional) A
regex pattern to match a specific build log filename.
The deserialized artifact value, or the in-memory value.
