"""Scenario: the Librarian (Board Program) loop end to end.

Mirrors test_sentinel_loop.py's arm -> originate -> dedup shape (same
RoboCo-project resolution — org scope means no per-project opt-in is needed
to RUN, but the exploration task's project_id still resolves against the
RoboCo project, a hard TaskService invariant every non-coordination task
carries) AND its do_server wiring-regression check + real-route propose call.
Unlike a quality report, propose_playbook_drafts' output is REAL playbook
rows (not just a task marker) — this asserts they land as PENDING/DRAFT
playbooks riding the normal curation queue, in addition to the mining task
completing.
