The mesh's own ban chain is a ban wherever it hangs; the front end's record is cited as 0180 (hq ADR 0186)

The legacy reader required every path into a chain of refusals to come from a built-in whose policy
accepts. The home server's ban chain hangs off the container runtime's user chain, whose forward
policy the runtime set to DROP, so the machine reported the mesh's own intrusion prevention as a
rule set the mesh did not write. A chain is a ban when every refusal names its sources and the
chain accepts nothing — the rule the nftables side already used. A chain that accepts anything is
still not a ban. Fixture captured from the machine. The citations for the uninstalled front end move
to ADR 0180, which another session's renumber had left pointing at an unrelated record.
