Module execution 

Execution cluster.

• runner: the Runtime graph engine and step orchestrator.
• graph: graph loading and step lookup helpers.
• fanout: fanout policy helpers shared across runner and harness.
• harness: harness fixture replay and assertion engine.
• orchestrator: canonical entrypoint for local skill, graph, and harness execution.
• skill_front: the skill front; compiles a skill run into an execution and seals it through the act engine.

Modules

harness

orchestrator

Canonical local orchestration entrypoint.

runner

The act engine for runx: the single admit -> execute -> seal path every run takes. A standalone skill is a one-act plan and a graph a multi-act plan; both run through this one engine.

skill_front

The skill front: compiles a skill-run request into an execution (cli-tool, agent, or graph runner) and seals it through the shared act engine. This is one of the source-type “fronts” from plans/governed-execution-layer.md; the act engine (execution::runner) owns admit -> execute -> seal.
