"""Run one read-only cite-check worker for each prepared brief unit.
The runner is deliberately small at the orchestration boundary: preparation
owns the unit inventory, this script owns the six-wide fan-out, and the
downstream report owns presentation. A worker's citation rows are semantic
results; the runner never predicts, filters, or rewrites them from a parent
citation inventory.
