Not approved as drafted -- four things came out of checking them against each other, and one was a bug that would have broken every upgrade. The bug: 0059 specified Restart=on-failure while 0057 has the host restart onto a new binary by exiting CLEANLY. on-failure does not restart a process that exited zero, so every upgraded node would have been left stopped, having successfully upgraded. Found by reading the two records against each other rather than by either alone. Now Restart=always in all three places that mention it. The host cannot run in a container, and the reason is decisive rather than stylistic: step 0 of the substrate bootstrap installs the container runtime, so a host inside a container would need the thing it exists to install. It would also break 0041 -- copy it onto a machine and run it stops being true when the machine must already have a runtime. Everything above tier 0 is a container; the host is not. That split is the tier boundary, not an inconsistency. systemd is named rather than abstracted. An init is not a dependency in 0041's sense: 0041 is about what must be installed before the host works, and an init is not installed, it is what the machine already is. The unit file is the only systemd-specific artefact and it belongs to the package, so a machine with a different supervisor ships a different package. The mesh is a watchdog, and my first draft was half an answer. Recovery must be local -- nothing dials a node, and a host that cannot start cannot report. But detection is the mesh's, and a local supervisor structurally cannot do it: it sees one process failing and cannot tell a broken machine from a broken release. Only something watching every node can, and that distinction decides whether the response is "fix this machine" or "stop shipping this version". So a host rollout is staged -- a few nodes, wait for heartbeats, continue or stop on silence. Local rollback still needed, because the canary nodes break and because a node offline during the rollout gets the declaration later with no batch around it. The first declaration is the overlay and nothing else. Forced, because a node's address and peers are assigned rather than chosen. But also the way back in: a node reachable over the overlay can be fixed by hand if a later declaration breaks it, and a large first declaration risks a node that is broken and unreachable at once. Also stated plainly, because it reads as a contradiction: nodes reach each other over the overlay and every node consumes from the broker; what 0039 forbids is an inbound CONTROL surface, not reachability. And in 06: no node holds a credential to any control-plane store, for reads or writes. Four ADRs already say this separately and none of them said it in one place. Nodes state over the broker; the owning context writes. With a note that most high-frequency writes are observability's, not the registry's -- routing logs into the registry would be the shared-schema mistake arriving through a door marked performance.
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 asanchor,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.
