The filter constrains what arrives from outside, and names no network

The forward chain blocked everything passing through the machine and then allowed
the machine's own containers back by naming their address ranges: 172.16.0.0/12 and
192.168.128.0/17 fixed here, the rest recorded per machine by 0043. Every way of
keeping that list correct fails — a constant describes one machine, a recorded range
goes stale in silence and cannot tell a network the mesh made from one a predecessor
left behind, and generating it from the modules would put half the rule set on the
machine.

The mesh has no position on a container reaching outward: that is not a port opened
to anybody. So both chains are written around the links traffic arrives on. What did
not arrive from outside is accepted in one line; what did meets the declared rules.
The tunnel is named beside the outward links rather than treated as inside, or a port
nothing declares would be reachable from every machine in the mesh.

A machine that has not reported an outward link is sent no filter and keeps the one
it has, refused where a person reads it rather than as a rule set that will not load.

Removes the two constants, `node networks`, and the column behind it. novox/hq ADR
0140, superseding 0137 and 0139.
