jschoubben 9ee0c63c7a 0039: the link already exists, and most of the cost is already paid
Written first as though the link were a thing to build. It is not. ADR 0001
already has it — every node connects outbound to a single broker, nothing ever
connects to a node, each node declaring an exchange named for itself and
consuming from its own queue. Already outbound-only, already per-node addressed,
already the one channel everything arrives through.

So this record is not proposing a channel. It proposes that the channel carry
per-node identity instead of one shared credential. The same as-is records the
fault it fixes, for the broker rather than the database: the broker's credential
is mesh-wide, rotating it is a mesh-wide operation, and doing it wrong has taken
the broker down.

That reframes the overhead objection, which was fair against what the record
said and not against what it means. Of six properties, four are already true,
one is broker configuration — users, vhosts and per-queue permissions the broker
already implements — and exactly one is new machinery: enrolment. Meanwhile 0037
subtracts, since a node under it holds no database credential at all. Three
hand-carried shared secrets become one identity that grants only identity.

Adds the option that was actually being weighed and was missing: accept the
exposure as the cost of simplicity. Rejected because the simplicity IS the
unfixability — the credential cannot be rotated precisely because everything
holds the same one.

And adds a requirement from the debugging objection, which was the strongest
part of it: it must fail legibly. A boundary that refuses a node without saying
why is worse than the password it replaced, because a wrong password at least
announces itself. That is §5 applied to a security mechanism.

Novox HQ

The single source of truth for what Novox builds — what it is, what it is becoming, and why. Today that is almost entirely Novox Mesh, the substrate everything else runs on. Implementation lives in modules/; the reasoning behind it lives here.

Structure

Folder Purpose
00-META Mission, foundational context, the rules that hold across the mesh, the repository map, and the process playbooks. The northern star for every decision.
01-RESEARCH Active and historical investigations, before they harden into design.
02-DECISIONS Numbered decision records, in the order the decisions were taken — what was chosen, and what was rejected.
03-DESIGN The authoritative specification, in two layers: 00-as-is — the mesh that exists — and 01-to-be — the one being built toward.
04-ISSUES The front door for "something is wrong" at the level of design or governance.

The numbering is the flow. Research produces a decision; the decision authorises a design. That is why decisions are 02 and design is 03 — a reader following the numbers walks the process in the order it happens.

The flow

idea ──► 01-RESEARCH ──► decision (02-DECISIONS/) ──► 03-DESIGN/01-to-be ──► built (code repo)
 │            │                                      │
 │            │                                      └─► 03-DESIGN/00-as-is once shipped
 │            └────► abandoned (recorded, kept)
 └─(small/obvious, still recorded in 02-DECISIONS)──────────► 03-DESIGN directly

symptom ──► 04-ISSUES ──► diagnosis ──► code-repo fix and/or design amendment

00-META/how-we-build.md ──► sync ──► the constitution the mesh injects into design sessions

Implementation lives in the code repositories — see 00-META/repos.md. Every workflow is a playbook in 00-META/process/; agents operate through them and not outside them.

Rules

  • Markdown only.
  • No new top-level folders without explicit confirmation.
  • Knowledge flows GENESIS → RESEARCH → DESIGN. Research graduates into design only after analysis against GENESIS confirms alignment, and only through a recorded decision.
  • Status lives in frontmatter, never in a central status file. Cross-cutting views are generated on demand, never hand-maintained.
  • GENESIS and DESIGN are instance-agnostic. They describe the mesh as a concept — no machine names, no counts, no topology. A reader must not be able to tell how many nodes the author happened to have.
  • RESEARCH describes real observations, but never identifies the mesh it observed. Evidence is what makes research worth reading, and the shape of a finding survives anonymisation intact — a node publicly named but behind a household NAT carries the whole lesson without naming anything.
  • The as-is layer records what is, not what should be — including behaviour nobody would choose again. A layer that keeps only the good decisions is a brochure.
  • A document that states a rule about the mesh should say how that rule is checked. This repository has a rule requiring every capability-exposing module to declare the core runtime as a dependency; zero modules do. An unenforced rule is indistinguishable from a wrong one.

This repository is public

Written for a reader who is not its author and has no access to the mesh it describes. Concretely, nothing here may contain:

  • routable addresses, real domain names, hosting providers, or node names — use the documentation ranges (RFC 5737 203.0.113.0/24, RFC 1918) and role names such as anchor, home-server, workstation, laptop
  • absolute paths from anyone's machine, usernames, home directories, or email addresses
  • credentials in any form, including lengths or hashes of live secrets
  • operational detail that is only useful to an attacker — which host is the VPN hub, on which port, which node is reachable only through a forwarded port

Private-range addresses and the overlay plan are fine: they describe a pattern, not a target.

The test is whether a paragraph would still teach something to a stranger running an entirely different mesh. If it would, it belongs. If it only makes sense to someone who knows this particular installation, it is either a note in the wrong place or a disclosure.

Why this is its own repository

It began inside the code repository, on the reasoning that the mesh already has a mesh-native knowledge store and that adding a fourth knowledge system would repeat the mistake this folder was created to fix.

That objection was about a fourth knowledge system, and the answer offered was indexing rather than location — that these documents would be indexed into the knowledge base, so a symptom search returns them beside everything else. One source, many surfaces. Where the source is authored is then a separate question.

That indexing does not exist. It was checked on 2026-08-23 and returns nothing; it appears never to have existed. Until it does, the objection stands unanswered and this repository is the fourth knowledge system it was argued not to be. Recorded as 04-ISSUES/006, and left standing here rather than quietly reworded, because a claim that held up a decision and was never checked is precisely the failure this repository exists to name.

Answered separately, a repository of its own is the better home:

  • The cadence is different. A decision changes when thinking changes, not when code changes. Tying documents to a code branch means they merge on the code's schedule.
  • The reviewers are different. A design argument is not reviewed the way an implementation is, and it should not queue behind a build.
  • The scope is wider than one repository. ADR 0015 sends most modules out of the monorepo entirely. Documentation that governs several repositories cannot live inside one of them.

The trade is real and worth naming: a change to a document and the change to the code it describes can no longer land in one commit. Keeping them honest is a discipline now rather than a mechanism — which is why every decision is recorded in 02-DECISIONS as it is taken, and why a document that states a rule should say how the rule is checked.

Recorded as ADR 0019.
