jochen db5e7c80cf The packet filter's tools are a bundle the node's runtime serves; its container goes (hq to-be 38 WP4)
nftables drops its container, NET_ADMIN, the container-runtime capability, the runtime base
images, the Dockerfile, and the bus credential and state directory only the container read;
its tools are declared as a TypeScript bundle the toolchain compiles and node-tools loads on
every node, and the iptables package the image used to carry is declared on the host. The
runtime runs as the operator's account, so the tool runs the filter's commands through sudo
without a prompt when it is not root (ADR 0175 §4, to-be 38 WP4), naming sudo's absence or
refusal by how it failed; the filter file is the path the manifest's filtering names, held to
it by a test; a found firewall that is present but will not answer stops a removal rather
than passing for inactive; a legacy tool that is present but fails is said, not swallowed.

jschoubben b77582f6a6 Cite hq ADR 0170, not 0169: the firewall seat's record was renumbered after a collision on hq main 2026-10-02 14:52:26 +02:00
jschoubben 663e8143d4 nftables holds the node-packet-filter seat: rules, reload and remove, from a runtime with NET_ADMIN (hq ADR 0169)
The seat's three verbs over the machine's own tools: the filter as enforced
(nftables and the legacy filter), the mesh's own table reloaded from its file,
and one rule set the mesh did not write removed by the name the host reports
it under (ADR 0168) — a predecessor's chain loses its jumps and goes, the
runtime's user chain is emptied back to its return, a table of the machine's
own goes whole; the mesh's tables, the runtime's chains, a built-in chain and
an active found firewall's chains are refused. Tested over the shapes two
machines of the first mesh reported live. The module's own tool stays.

jschoubben 71bbc7dab0 Name the two modules after their software: nftables and distribution
A module's identity is the software it is (ADR 0040). Two were named after the
job instead, and the job already had a name.

firewall installs the nftables package and runs nftables.service. The seat it
claims is the-packet-filter, which is correctly named for the role. Calling the
module firewall named neither the software nor the provision, and promised that
any firewall could sit there — the false genericity the naming rule forbids.

registry runs Distribution, the OCI reference implementation, and provides
artifact-store. So registry was a third name for a thing that already had two,
which is how one word ended up meaning the module, the software and the concept
in the same paragraph.

The capability stays firewall, and correctly: a capability IS a functionality, so
a node having one and fail2ban requiring one are both right. Only the module
moves.
