Feature Area

Actor System Compilation — GRAPH-type actor subgraph node resolution

What Was Tested

Code-level analysis of src/cleveragents/actor/compiler.py, src/cleveragents/actor/schema.py against the specification's subgraph node configuration.

Expected Behavior (from spec)

Per docs/specification.md line 20559, the subgraph node type uses actor_path as the config field:

| `subgraph` | `actor_path` | Embeds another actor as a nested workflow |

Actual Behavior (from code)

The compiler (src/cleveragents/actor/compiler.py) reads actor_ref from node.config:

# Line 140
subgraph=(config.get("actor_ref") if node.type == NodeType.SUBGRAPH else None),

# Line 197
ref_name = node.config.get("actor_ref", "")

# Line 293
ref = node_def.config.get("actor_ref", "")

Additionally, NodeDefinition in schema.py (lines 451-454) has actor_ref as a top-level field on the node, not inside config:

actor_ref: str | None = Field(
    default=None,
    description="Namespaced actor reference for subgraph nodes",
)

This creates a three-way inconsistency:

Spec: subgraph config uses actor_path
Schema: actor_ref is a top-level NodeDefinition field (not in config)
Compiler: reads actor_ref from node.config (not from node.actor_ref)

Impact

Subgraph nodes in GRAPH actors cannot correctly reference other actors.
The compiler's _detect_subgraph_cycles() and _map_node() both read from the wrong location (node.config.get("actor_ref") instead of node.actor_ref).
Users writing YAML with actor_path (per spec) will have their subgraph references silently ignored.
Users writing YAML with actor_ref in the config block (per compiler expectation) will also fail because the schema stores it as a top-level field.

Steps to Reproduce

Create a GRAPH actor YAML with a subgraph node using actor_path: local/my-sub-actor
Compile the actor via compile_actor(config)
Observe: subgraph reference is not resolved (compiler reads config.get("actor_ref") which returns None)

Code Location

src/cleveragents/actor/compiler.py lines 140, 197, 293 (reads actor_ref from node.config)
src/cleveragents/actor/schema.py lines 451-454 (actor_ref is a top-level NodeDefinition field)
docs/specification.md line 20559 (spec says actor_path)

Fix Suggestion

Align the spec, schema, and compiler on a single field name (recommend actor_ref as it's more descriptive)
Update the spec to use actor_ref instead of actor_path
Fix the compiler to read node.actor_ref (the top-level field) instead of node.config.get("actor_ref")
Update _detect_subgraph_cycles() to use node.actor_ref as well

Architectural Decision

After reviewing the three-way inconsistency, the correct design is actor_ref as a top-level field on NodeDefinition (as implemented in schema.py line 451).

Rationale: Placing actor_ref as a typed top-level field is cleaner than burying it in the untyped config: dict[str, Any] block. The schema's Pydantic model correctly validates the namespace/name format via validate_actor_ref. Putting it in config would lose this validation.

Spec fix: PR #5488 updates the spec to document actor_ref as a top-level field (not in config) and renames it from actor_path.

Implementation fix needed (tracked in this issue):

Fix compiler.py lines 140, 197, 293: change node.config.get("actor_ref") → node.actor_ref
Fix schema.py docstring line 418: change SUBGRAPH: {"actor_path": "path/to/actor.yaml"} → SUBGRAPH: actor_ref: "namespace/actor-name"

The spec PR (#5488) is a prerequisite for the implementation fix — implementers should wait for it to merge before fixing the compiler.
