"""Strict Blockbuster runtime context scoped to DeerFlow business code.
|
|
|
|
Creates a `BlockBuster` instance with `scanned_modules=("app", "deerflow")`
|
|
so that test infrastructure (pytest, langchain, importlib, third-party libs)
|
|
is out of scope and does not produce false positives. Only loop-blocking
|
|
sync IO whose caller stack passes through `app.*` or `deerflow.*` raises
|
|
`BlockingError`.
|
|
|
|
Used by `backend/tests/blocking_io/conftest.py` to gate the regression suite.
