Workflow Delegate And Memory Steps
==================================

Source: ``examples/workflow/workflow_delegate_and_memory_steps.py``

Introduction
------------

Generative Agents and MemGPT both emphasize durable memory as a first-class runtime primitive, while AutoGen
demonstrates delegation across specialized roles. This example composes delegate and memory steps in a
single workflow so context propagation and role handoff remain explicit.

Technical Implementation
------------------------

1. Configure ``Tracer`` with JSONL + console output so each run emits machine-readable traces and lifecycle logs.
2. Build the runtime surface (public APIs only) and execute ``Workflow.run(...)`` with a fixed ``request_id``.
3. Capture structured outputs from runtime execution and preserve termination metadata for analysis.
4. Persist and query context via ``SQLiteMemoryStore`` to demonstrate memory-backed workflow behavior.
5. Print a compact JSON payload including ``trace_info`` for deterministic tests and docs examples.

Expected Results

.. rubric:: Run Command

.. code-block:: bash

   PYTHONPATH=src python3 examples/workflow/workflow_delegate_and_memory_steps.py

Example output shape (values vary by run):

.. code-block:: text

   {
     "success": true,
     "final_output": "<example-specific payload>",
     "terminated_reason": "<string-or-null>",
     "error": null,
     "trace": {
       "request_id": "<request-id>",
       "trace_dir": "artifacts/examples/traces",
       "trace_path": "artifacts/examples/traces/run_<timestamp>_<request_id>.jsonl"
     }
   }
