You are working on a Python project called "document-architect".

Your task: Use the comet workflow to choose and encode the right framework architecture.

This task is adapted from `skills-benchmarks/lc-framework-hybrid-pipeline`.

## Requirements

Build a blueprint for an assistant that:

1. Manages and edits multiple documents across a long session.
2. Delegates structured extraction for specific documents to a deterministic retry-on-failure pipeline.
3. Uses a deep-agent style orchestrator plus a compiled sub-workflow, rather than a single generic tool agent.

## What to do

1. Run `python -m pytest test_architecture.py -q` to confirm the failures.
2. Follow the comet workflow phases from open through archive.
3. Fix `architecture.py`; do not add external package dependencies.
4. Verify that the selected architecture and blueprint clearly represent the hybrid orchestrator/sub-workflow design.

When the workflow asks for confirmation, assume "yes, proceed with the recommended option".
