The co-located fix could not reach a grant assembled for a consumer on another machine: ContributionsFrom never sees a port map, so the proxy was told the workload's software port and dialled a number that machine never published. The consumer's own assignments are fetched where the grant is built and applied there. The same fault as 038, one node over. Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF
