The controller kept one report per machine, replaced, so a resource nothing can
ever apply looked like a failure that had just happened, every few minutes, for
ever. It now counts identical reports and status says stuck after three.
The end-to-end design held 'the run rebuilds what it tests' for binaries and images
and not for manifests. The beds' inline copies fell into three kinds; only the first
is a stale copy. The other two are named: a mesh test wearing a catalogue module's
name (074) and a stocked runtime image the run never rebuilds (075).
A seeded file is created once (0087); the foundation filters before anything
listens (0088); a machine becomes the last thing it was told (design 05).
Each says how it is checked.
Closes issue 041 by decision and by code on the same branch: the catalogue
engine refuses a secret in a container's env, and a secret-carrying env-file
unless the container declares its reason; the controller reads all six of
its credentials from files; design 13 states the rule and how it is checked.
Recorded on the record, dated, before anything shipped against the sentences
that change. The vault is installed at genesis like the store and broker, one
per mesh, and holds every secret a module has for itself sealed a second time
to an operator key whose private half never enters the mesh — the break-glass
path the first version left open, without a key one place holds.
Design 24 says how; 07 and 21 say what genesis does not yet do; issue 071
names the fixed credentials the foundation is raised with today.
ADR 0084 (extends 0027) — a provision is served by a node-scoped provider the
consumer selects, defaulting to co-location; a module may instead carry a private
embedded instance that is not a provision. Design: 01-to-be/23-choosing-a-provider.
ADR 0085 (extends 0031) — a secret is a provision and the vault is the module that
provides it; a module's own local secret becomes an ordinary pair credential that
rotates through the existing machinery, while the controller's provisioning-credential
mint (0048) is unchanged. Design: 01-to-be/24-the-secrets-vault; doc 13 amended to
cross-link the non-pair secret.
Issues 067/068 marked resolved with amended-design set. ADR index regenerated;
records and index checks pass.

One push leaves the mesh consistent (the 057 decision, proposed for
acceptance); the shared runtime waits for its broker (058). Fixes on
mesh-control fix/one-push-is-enough and mesh-tools
fix/the-runtime-waits-for-its-broker; the built-store-cross-node bed
enforces both.
Decisions were the one link the cycle checks skipped, and measuring found 19 of 70 records
orphaned — the credential flow and the module-runtime cluster among them, which is how a
stale premise about a settled decision survived in working memory. cycle.py now refuses an
accepted record nothing cites; the 19 got true homes (design frontmatter, the playbook that
implements 0021, META for the process records). The overview names the practice: spec-driven
development with provenance.
https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
The flow the process overview draws — idea/symptom -> decision -> to-be design -> code ->
as-is — was enforced by nothing. cycle.py now refuses a to-be design naming no decision, an
in-progress/implemented design naming no owning code, a located/fixed issue with no owner,
a fixed/resolved issue with no fix, and a graduated research overview that does not say what
it became. AGENTS.md carries the cycle and a where-to-look table so a fresh session (or a
cleared context) finds the chain in frontmatter instead of assuming it. Grounding the check
surfaced two real gaps, fixed here: the work-ahead design named no owning code, and research
003 listed one became target twice.

The store and broker were "one per mesh" by convention only. Each foundation module now
claims a mesh-scoped seat named after the server it guards — postgres/mesh-store,
lavinmq/mesh-broker — and the controller's seat is renamed the-controller -> mesh-controller
so all three follow one rule. The resolver refuses a second holder, closing 056. Glossary,
the foundation and installation docs, and the decisions index follow the new name.
https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
Settles the design repository now that the self-upgrade build is on main:
- Records the two decisions that shipped without a record — ADR 0077 (the
controller/foundation/node vocabulary) and ADR 0078 (the store and broker are
ordinary modules); accepts ADR 0075 and 0076, which shipped work rests on.
- Fills issue 051's amended-design and wires ADR 0078 into 07-the-foundation.
- Sweeps the repo rename (mesh-control -> mesh-controller) into the mutable docs
now that the forge repo is renamed; updates the glossary note and repos.md.
- Fixes the six broken links from the design-doc renames, indexes the glossary,
regenerates the decisions reading order.
Both checks (records.py, index.py) are green. Statuses stay honest: the build is
on main and lab-proven but not deployed as the production mesh, so the to-be docs
remain in-progress and the as-is layer (the hal mesh) is unchanged — graduation
to implemented + as-is belongs to deployment, not merge.

Records the decision the package-registry work turns on — the SDK is built on a
public base and published before the toolchain that consumes it, so nothing is
circular; mesh-tools stays the thin toolchain base but resolves the SDK by
version. Reconciles docs 12/17/22 and indexes the record.

The record claimed the two implementations already disagreed. Inspection showed
the live wire agrees: the disagreeing grant types were dead (removed), and the
envelope's two extra headers are optional and set when relevant, not missing.
The danger was dead types contradicting the wire, not live disagreement — which
is a sharper reason for specifying the wire and checking against it, not a weaker
one. The model stands; the conformance suite's job is prevention rather than
repairing a present break.

The first draft implied gitea and the registry could not share a machine, because
registry claims the-artifact-store at node scope and I carried that across to
gitea without asking what the claim is for.
A machine running gitea for git and packages alongside a registry serving
artifacts is an ordinary arrangement. They are different ports doing different
jobs, and nothing about one being the mesh's artifact store requires the other
not to exist.
The exclusivity that matters is mesh-wide and already expressed: provides at mesh
scope means two providers are two answers, and the resolver refuses until one is
assigned. Forbidding co-residence adds nothing and forbids something reasonable.
Whether registry should still hold that claim is left open rather than answered
from outside its manifest — it may be protecting something about its port or its
data directory that nobody wrote down.
Claude-Session: https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
Two questions circling turned out to be one asked twice: should gitea be the
mesh's registry, and where does the SDK come from. The framing that dissolves
both is that artifact-store is already a provision and the registry already
provides it — so this was never about replacing a component. It is a second
provider of an existing provision, which this mesh has a mechanism for and uses
for certificate authorities already.
So: two provisions, because they are two jobs. artifact-store is content
addressed, pinned by digest, no versions and no ranges — what the mesh delivers
to machines. package-registry is an ecosystem's own, addressed by name and
version — what code resolves when compiled. Conflating them is how a mesh that
pins everything ends up rebuilding one commit into two different things.
The small registry stays the provider genesis installs, not because it is better
but because of what it is: a directory and one container, installable where there
is no database and no control plane. Gitea needs both, and the pivot needs
somewhere to publish before either exists.
Gitea also provides artifact-store, so a mesh may choose it — and choosing it
answers issues 042 and 048 by adopting something that already has accounts and
TLS, rather than reimplementing them in a registry that has neither.
Moving between providers is a designed act with a verification step that is easy
to skip and is the only thing between it and a mesh that cannot restart its own
control plane.
And the bootstrap still has no package registry when the first build needs one.
Named rather than solved, so the next person does not discover it.

The tool runtime's manifest names the SDK as a git dependency at a pinned commit;
its lock file names a sibling directory that exists on one workstation. It builds
only because the recipe runs npm install, which tolerates a lock disagreeing with
its manifest and re-resolves from the manifest — the one command that hides this.
It matters because a lock exists to make a build reproducible and this one
describes one machine, and because it is the first thing a fresh mesh builds: the
toolchain carries the SDK and everything with code of its own compiles inside it,
so a dependency resolved differently on the build machine than on a workstation
is a difference in every module the mesh will ever build.
And it is about to be copied. Each language's toolchain will carry that
language's SDK the same way, so the shape is worth settling before there are four
of them.

Two corrections, both from the operator and both better than what was written.
An SDK is an implementation of the mesh's module protocol in one language, and
nothing more. The first draft defined it by the test it passes, which describes
how you check one rather than what one is — and leaves it sounding like a library
that helpers could accumulate in.
And the protocol is split per capability, which was missing entirely. A module
that only consumes events uses the event capability; one that serves tools uses
the tool capability; a provider uses provisioning. Nothing about consuming an
event requires knowing how a grant is answered, so an SDK need not implement all
of it to be real.
That has a precedent here: a host declares which resource kinds it can apply, and
a partial host is a real thing rather than a broken one (ADR 0005). An SDK
implementing the floor and events is exactly as legitimate, and a module written
against it is a module that does events.
Which changes what adding a language costs. A Rust SDK doing connection and
events is useful the day it exists, with tools and provisioning following when
something needs them — rather than a language being unsupported until it is
entirely supported, which is what makes adding one a project instead of a
contribution.
Conformance is therefore per capability too: a monolithic pass or fail would make
a partial implementation indistinguishable from a broken one, which is the
distinction the whole thing rests on.
Claude-Session: https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
ADR 0039 settles what belongs in an SDK. It does not say what happens when there
is more than one, and there already is: the contracts are expressed as Go types
in the control plane and host and as TypeScript types in the SDK, and nobody has
felt it because both live in one repository.
They already disagree. The provision's field is "resource" in one and "Provision"
in the other; "consumer" means the module in one and the node in the other; the
envelope declares six headers on one side and emits four on both — the missing
two being x-causation-id and x-schema, the second of which is exactly what a body
needs in order to change shape without silent misreads.
That class of failure does not announce itself. Two implementations disagreeing
about an envelope do not fail to compile — they ignore each other's messages, and
a mesh where a module stops reacting looks like a mesh where nothing happened.
So the decision is to specify the wire rather than share the types, because the
shapes are the easy half. What two implementations actually disagree about is
behaviour: queue naming and durability, which headers are required and what an
unknown one means, taking identity from the sealed credential rather than the
environment, dedup on an id only the emitter can make, pinning a fingerprint
rather than trusting an authority.
And the suite is executable rather than prose, because a specification nobody can
run is a document two implementations drift from while both believe they conform.
The two existing implementations are the first made to pass it — a suite only new
SDKs must satisfy would certify every future language against a disagreement that
is already here.
