The mesh's filter is composed from every module's listens, why text included,
and the renderer fills every ${port:N} it finds in a written file — refusing
one the writing module did not declare. Two why texts quoted the env lines
WEBUI_PORT=${port:8112} and TORRENTING_PORT=${port:6881} literally, so the
filter file on a converging node named qbittorrent's ports as nftables' own:
"nftables has a file that says ${port:6881}, and nftables does not say it
listens on 6881" (ace, 2026-10-01). Said in words instead.
