Major refactor of the message pump architecture:
- Replace bus.py with stream_pump.py using aiostream for composable
stream processing with natural fan-out via flatmap
- Add to_id field to MessageState for explicit routing
- Fix routing to use to_id.class format (e.g., "greeter.greeting")
- Generate XSD schemas from xmlified payload classes
- Fix xmlable imports (absolute -> relative) and parse_element ctx
New features:
- handlers/hello.py: Sample Greeting/GreetingResponse handler
- config/organism.yaml: Sample organism configuration
- 41 tests (31 unit + 10 integration) all passing
Schema changes:
- envelope.xsd: Allow any namespace payloads (##other -> ##any)
Dependencies added to pyproject.toml:
- aiostream>=0.5 (core dependency)
- pyhumps, termcolor (for xmlable)

- Minimal, universal base for all capabilities
- Required listens_to class attribute
- Async handle() with convo_id preservation rule
- make_response() helper for thread continuity
- Explicit name, config, per-instance logger
- Clear documentation and NotImplementedError guard
This is the true substrate the entire organism will build on.
