"""Smoke coverage for the deploy-time canary baseline seed.
The deployer hook calls ``decnet.canary.planter.seed_baseline`` for
every running decky. Two properties matter:
* a baseline seed runs, producing one token row per configured
generator; and
* failures in seed_baseline must never abort the surrounding
deploy flow (resilience principle).
We don't drive the full ``deploy()`` here — that pulls in docker,
network helpers, etc. Instead we exercise ``seed_baseline``
directly with the planter's docker-exec patched, then assert the
hook's wiring via static inspection.
