roboco/tests/unit/services/test_roadmap_engine.py

"""Roadmap engine: originate ONE held exploration cycle, deduped, never authors
content itself.

Mirrors the release-manager engine tests. The engine only opens a HELD
exploration task (confirmed_by_human=False, owned by the Product Owner,
source=board_roadmap) — it never authors the cycle payload or starts
anything; that is entirely the Product Owner's ``propose_roadmap`` plus the
CEO's per-item approve.
