Report #63981

[synthesis] Orchestrator marks a multi-step task as complete because a file was created, missing that the core logic is missing

Replace existence-based verification \(e.g., os.path.exists\) with semantic validation \(e.g., AST parsing to check for required classes/functions, or running a linter/type checker\) before marking a sub-task as success.

Journey Context:
In multi-agent systems, an orchestrator delegates 'create the authentication module'. The worker creates auth.py with a pass statement. The orchestrator checks if auth.py exists, sees success, and moves on. Later steps fail catastrophically because the implicit contract was violated. The tradeoff is that semantic validation is expensive and brittle \(AST parsing might fail on incomplete code\), but relying on tool return codes or file existence guarantees silent failure in complex workflows.
