Two related fixes that came out of running the W5 tests locally:
1. tests/__init__.py — empty file, makes 'tests/' a package so pytest
stops inserting it into sys.path. Without it, 'tests/docker/'
(the docker-image test category) shadowed the installed docker SDK
on every engine-touching test in the repo:
module 'docker' has no attribute 'DockerClient'
Pytest's default --import-mode=prepend was the culprit; making
tests/ a package is the cheapest fix and doesn't change
--import-mode for the whole tree.
2. delete_topology_decky / delete_topology_edge / delete_lan grow an
'enforce_pending: bool = True' kwarg. Default preserves the HTTP
CRUD guard (api_decky_crud / api_edge_crud / api_lan_crud get the
409 for free). apply_remove_decky / apply_detach_decky /
apply_remove_lan now pass enforce_pending=False — the mutator
queue is the live-editing surface and has its own active-topology
gating; the repo's pending-only guard was for design-time CRUD
that mustn't bypass it. Without this, apply_remove_decky was
silently broken on active topologies pre-W5; W5's new test
surfaced it on first run.
10/10 new W5 tests pass; 58/58 across mutator + topology suites.
