"""Scenario: the generic Board Program loop end to end (Task 9).

Drives the REAL ``BoardProgramEngine`` (not a mock) against a REAL Postgres
through the harness: arming the roadmap program via the new per-program
settings-store key opens ONE held exploration task the delivery dispatcher's
pending-claim filter skips (it's board-dispatched, not delivery work); a
second tick dedups (no second task/cycle row); and approving a fake item
through the real ``RoadmapService`` moves the LEARN ledger's counters.
