Root cause: test_schemathesis.py mutates decnet.web.auth.SECRET_KEY at
module-level import time, poisoning JWT verification for all other tests
in the same process — even when fuzz tests are deselected.
- Add pytest_ignore_collect hook in tests/api/conftest.py to skip
collecting test_schemathesis.py unless -m fuzz is selected
- Add --dist loadscope to addopts so xdist groups by module (protects
module-scoped fixtures in live tests)
- Remove now-unnecessary xdist_group markers from live test classes
