FN-8704 failed at the graph parse node because PROMPT.md was only "DUPLICATE: FN-8676". Filesystem validation treated non-empty as planned and admitted the card into WIP, which then looped on parse failure. Treat a sole DUPLICATE redirect as unplanned: block dispatch and hold release, badge as awaiting planning, and if parse still sees that shape rebound to needs-replan with feedback instead of parking failed.
