Filed 2026-09-24 on a branch of its own and never merged, numbered 113, which is taken. 114 is
free because a sibling branch folded it, so it takes that number and keeps its commit.
Kept separate from issue 117 rather than folded into it. 117 asks the same question of every
module and locates the missing decision; this asks it of the controller, where `network: host`
means container network isolation — the property that resource type usually buys — is not in use.
That observation is this report's own and is nowhere in 117, and folding would lose it.
Its first open question is answered by 117's diagnosis and now says so: the host's `process` shape
is built, applied and tested, restart and run-to-completion semantics included, so deciding this
does not wait on host-side work.
Filed after a session where every mesh-controller interaction went through
docker exec — its manifest runs it as a container with network: host, using
none of the isolation that resource type usually buys, while ADR 0006 makes
it the mesh's single point of coordination. Open question, not a claimed
defect: does type: container get the controller anything type: process
(supervised the way the host supervises its own unit, per ADR 0005) would not.
Asked what the "sidecar" is and whether a supervised process would do instead. The repository
answers both ways. ADR 0047 (accepted, unsuperseded) says a module with tools or events runs a
container carrying its compiled code. To-be 18 and 20 (both proposed) define a `process` resource
type — the module's own code, a unit the machine's supervisor keeps up — and the worked guide says
plainly "it is why these are `process` rather than four containers." Neither design doc names 0047,
and no decision record mentions a `process` shape at all.
Diagnosed rather than left open, because the ground truth settles what the report could not.
The shape is real: mesh-host defines TypeProcess, applies it, and tests it, and the host's
vocabulary is twelve shapes rather than the nine ADR 0029 counted. So the alternative the report
offered — that two proposed documents describe a type that does not exist — is disproven.
ADR 0029's mechanism is intact and was not enough. The vocabulary-count test names the decision
behind each addition: network 0029, access 0051, opening 0100. The eleventh names a *proposed
design document*, and TypeProcess is the only shape in the vocabulary whose doc comment cites no
ADR. Requiring every addition to name something does not require it to name a decision.
The argument this issue asked for already exists — as a Go test comment. "It is a full-host shape
rather than a portable one: it needs a process supervisor to install into. It does NOT need a
container runtime, which is the point — only software that genuinely needs isolation asks for a
container." That is a decision's context and consequences, in another repository.
What the catalogue does is a third thing: 115 container declarations against 3 process, all three
in showcase — the module to-be 20 documents. There the tools resource is a container running
`sleep infinity` on a bare upstream base with the broker credential mounted, and the tools and
provisioner entrypoints are run by nothing. That is the condition 0047 was written to end, back
in a new shape.
Where the isolation argument leaks is narrower than expected and worth having precisely: the
serving key and the credential shape both conform. But serveTools serves every registered module
over one broker connection, the runtime takes its modules from a comma-separated list, and
x-source is stamped from the single credential — so two modules in one runtime means the second's
events are attributed to the first. Nothing refuses it and no test asserts against it.
Located on hq rather than on a code repository: the implementation and the design layer agree,
and the missing thing is the record. Which shape is right is left open, deliberately — this
establishes that the question was answered in practice and never written down, not which answer
is correct.
One correction kept in the trail: the first search here was for len(Vocabulary()), found nothing,
and was two steps from being written up as "the mechanism ADR 0029 relied on is gone." The test
binds the slice to a local first. A negative search result read as a fact about the world is the
same error issue 113 recorded.
