The oauth router imported _nous_poller/_minimax_poller/_xai_device_poller
from web_server_oauth at module level, so tests patching the owning module
("hermes_cli.web_server_oauth._minimax_poller") patched a binding the
router never read. The REAL poller then ran on the leaked daemon thread,
called the live MiniMax token endpoint from CI, and the in-flight
getaddrinfo segfaulted the interpreter during a later test's fixture setup
(CI run 34323790818, tests/hermes_cli/test_web_oauth_dispatch.py flake).
Route the three pollers through the existing late() seam (web_deps), the
same mechanism every other monkeypatch-sensitive symbol in this router
already uses, so the patch wins at thread-spawn time. Regression test
proves the mock intercepts and the real poller body never runs; it fails
on the old module-level import (sabotage-verified).
