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

Mirrors test_periscope_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) PLUS the credentials gate (materialized drafts land in the X post
queue; drafting for nobody to post is pointless) AND
test_feature_spotlight.py's do_server wiring-regression check + real-route
propose call. The genuinely new piece: unlike periscope (which completes in
place with no separate artifact), a Megaphone post materializes into the
SAME X held-draft queue a feature spotlight does — zero new approval surface.
