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

Mirrors test_periscope_loop.py's arm -> originate -> dedup shape AND
test_feature_spotlight.py's do_server wiring-regression check + real-route
propose call. The genuinely new pieces: (1) origination needs a configured X
client (search_recent), unlike periscope which needs none — faked here via
``roboco.services.barfly_engine.build_x_client`` (uvicorn runs in-thread, same
process, so the patch reaches the live route handler too); (2) unlike a
market brief (one report, completes its own task) a Barfly proposal
materializes N SEPARATE held x_barfly drafts through the shared
_originate_post chokepoint while completing the exploration task itself —
the x_feature-style asymmetry, multiplied.
