Once the collection-level blockers were fixed, the Windows runner finally ran the
suite and surfaced 7 pre-existing failures — all tests asserting Linux-only
behavior, while the production code already handles non-Linux gracefully:
- api test_secrets: chmod(0o000) can't make a file unreadable to its owner on
Windows (the 'unreadable -> None' precondition is unreachable)
- daemon test_scheduler_cron: patches fcntl.flock; fcntl is None on Windows
(scheduler_cron already skips locking on non-Unix)
- skills test_runner: system_status memory/uptime/processes/summary read Linux
/proc (skill returns a graceful error on Windows; disk test stays, it's portable)
Guard each with @pytest.mark.skipif(sys.platform == 'win32', reason=...). 68
tests pass on Linux, ruff clean, api+daemon audit 100%.
