Summary

The _map_node function in src/cleveragents/actor/compiler.py reads the actor_ref value for SUBGRAPH nodes from the raw node.config dictionary, ignoring the dedicated actor_ref: str | None field on NodeDefinition.

Code

`NodeDefinition` in `schema.py` (correct — has dedicated field):

class NodeDefinition(BaseModel):
    id: str
    type: NodeType
    config: dict[str, Any] = Field(default_factory=dict)
    actor_ref: str | None = Field(
        default=None,
        description="Namespaced actor reference for subgraph nodes",
    )

The actor_ref field even has its own validator:

@field_validator("actor_ref")
@classmethod
def validate_actor_ref(cls, v: str | None) -> str | None:
    """Ensure actor_ref follows namespace/name format when set."""
    if v is not None and "/" not in v:
        msg = f"actor_ref must be namespaced (namespace/name): '{v}'"
        raise ValueError(msg)
    return v

`_map_node` in `compiler.py` (wrong — reads from `config` dict):

def _map_node(node: NodeDefinition) -> lg_nodes.NodeConfig:
    config = node.config
    return lg_nodes.NodeConfig(
        ...
        subgraph=(config.get("actor_ref") if node.type == NodeType.SUBGRAPH else None),
        # ↑ Reads from config dict, ignores node.actor_ref
        ...
    )

The same problem also appears in _detect_subgraph_cycles:

def _detect_subgraph_cycles(...):
    for node in route_nodes:
        if node.type != NodeType.SUBGRAPH:
            continue
        ref_name = node.config.get("actor_ref", "")   # ← Also reads from config dict

Impact

SUBGRAPH nodes that set actor_ref: at the top-level YAML field (as validated by NodeDefinition.validate_actor_ref) will have their subgraph reference silently dropped during compilation — the compiled node will have subgraph=None.
Subgraph cycle detection will also fail to detect cycles for properly-configured subgraph nodes.
The actor_ref field validator in NodeDefinition validates the value but the compiler never reads it, making the validation useless.

Expected Fix

def _map_node(node: NodeDefinition) -> lg_nodes.NodeConfig:
    config = node.config
    # Use the dedicated actor_ref field for SUBGRAPH nodes
    subgraph_ref = node.actor_ref if node.type == NodeType.SUBGRAPH else None
    return lg_nodes.NodeConfig(
        name=node.id,
        type=lg_type,
        agent=config.get("agent") if node.type == NodeType.AGENT else None,
        function=config.get("function") if node.type == NodeType.CONDITIONAL else None,
        tools=config.get("tools", []) if node.type == NodeType.TOOL else [],
        subgraph=subgraph_ref,   # ← Use node.actor_ref
        metadata=dict(config),
    )

And in _detect_subgraph_cycles:

ref_name = node.actor_ref or node.config.get("actor_ref", "")

[AUTO-OWNR-1] Triage Decision (Cycle 12)

Status: ✅ Verified

MoSCoW: Must Have
Priority: High

Rationale: The _map_node function in compiler.py reads actor_ref from the raw node.config dict instead of the dedicated node.actor_ref field on NodeDefinition. This is a clear compiler correctness bug — SUBGRAPH nodes with a properly configured actor_ref will have their subgraph reference silently dropped (subgraph=None) during compilation, and cycle detection will also fail to catch cycles in correctly-configured subgraph nodes. The NodeDefinition.validate_actor_ref validator becomes entirely useless since the compiler never reads the field it validates.

Next Steps: Fix _map_node() to use node.actor_ref instead of config.get("actor_ref") for SUBGRAPH nodes, and update _detect_subgraph_cycles() to read from node.actor_ref as well. Add regression tests covering SUBGRAPH nodes with actor_ref set at the top-level field.
