Merge Node
Combine multiple inputs into a single output.
The Merge node is a planned logic node for combining multiple upstream branches into a single downstream flow. It is designed to take several inputs and present them as one output so the workflow can converge after a split.
Intended purpose
Merge is meant to combine multiple inputs into a single output, joining branches that were split earlier in the workflow back into one path. It is the natural counterpart to Conditional: where a Conditional node would fan execution out into separate branches, a Merge node would fan those branches back in. It belongs to the logic and control group, alongside Delay and Loop.
How inputs combine today
Builder Studio already lets multiple edges feed into one node, and the execution layer resolves those inputs through its port-binding logic before a node runs. Some content-display nodes also surface a placeholder like Connect inputs to merge when several sources feed one slot. A dedicated Merge node would formalize this into an explicit graph step whose only job is to collect upstream values and emit a single combined output, instead of relying on each consuming node to gather its own inputs.
