jschoubben 7fe2c31bdf Networking is a module, and what a domain module actually is
Two records, from building it.

0009 has a section titled "there are no domain modules", and `networking`
now exists. It is not a contradiction and it reads as one, so the
difference is written down: what was refused contains WireGuard and a
proxy and is assigned where half of it is unwanted. What exists contains
nothing — requirements and a name — so there is no half. Every artifact
it leads to is still an ordinary module assigned on its own terms.

With the cost stated, because it is real: adding a second implementation
turns a settled question into an open one for everyone using the bundle,
not only for whoever wanted the alternative. That is the refusing rule
applied consistently, and the alternative is a default, which is the
flavor field returning under a better name.

08-connectivity gains why the network stopped being code beside the
module system: a machine was on the private network because it had an
address, and there was no way to keep one off. A manifest can now say its
resources are computed, which is what a peer list needs.

And three modules rather than one, because WireGuard is one VPN of
several. Naming a module after the job and putting one implementation
inside it is flavor wearing a generic name — the second VPN has nowhere
to go.

03-DESIGN / 01-to-be

The mesh being built toward. Every statement here traces to a record in 02-DECISIONS/; nothing arrives by drafting.

A document here describes an intention. What currently runs is in 00-as-is/, and the two are never merged — when something ships, the as-is document is written and this one's status becomes implemented.

Not yet written

  • The remaining six contexts. ADR 0006 settles the list at seven; connectivity is the first written in full (08) and the other six do not exist yet. The work breakdown says in what order they are needed.
  • Domain grouping outside the core. Not needed. ADR 0009 is superseded by ADR 0009: there is no domain module to group into, so there is no domain list to settle. Relationships are edges, and grouping is a tag and a query.
