# Reprocess pending returns for one participant

> Drives the return-processing pipeline once for a single participant (poll, correlate, transition), the same per-participant work the return poll runs. RBAC: connectivity:admin. The participant ISPB is a path resource selector; the tenant is always taken from the validated request context, never the path. Inbound and not window-gated; it drives the idempotent return-processing pipeline, so it runs lock-free and is safe to run concurrently with the worker.
