The architecture 0117 opened needs a module to offer a service as a role on
the bus — one holder, addressed by what it does. A closed table in the
controller cannot express that: a capability a module contributes would
require changing the mesh itself.
But 0110 closed the set for a good reason — nothing could say what seats a
mesh had, and the hand count came out at eleven of thirteen. That argues for
enumerable, not hardcoded, and 0110 weighed free-form against a fixed table
without considering a third option: closed at any moment and derived from
the catalogue. A derived list cannot drift, which is how the count broke.
So: the mesh's seats stay the mesh's, reserved by the mesh- prefix so the
prefix is the rule and there is no list to maintain; ten seats are renamed
to restore 0079's convention; everything 0110 decided about what a seat IS
survives untouched.
Design 29 carries the declaration model: three namespaces, subjects derived
from local names so a manifest survives the wire changing, queues never
declared, five relationships (the job and state shapes 0041 had no room
for), and the build-publish-deploy lifecycle with hard, soft and build-time
dependencies distinguished.
0041 gets a progressive insight: "no per-consumer setup, only a
subscription" was a fact about a topic exchange, and a JetStream durable
consumer is a real object someone creates.
WBS 1.3/1.4 were wrong and say so: streams come at registration and
consumers at assignment, so only the foundation set belongs at genesis.
The seats half of to-be 27's review is settled, so the two records it rests on are accepted and
the vocabulary catches up: the glossary's *seat* becomes a named role from a closed set, held by
an assignment and possibly delivering a provision, and 23 — Choosing a provider gains the seat
step in resolution, with ambiguity still refused rather than guessed. Both were held back when
0110 was proposed, because a document may not rest on a record that is not accepted.
26 — The seats moves to in-progress rather than designed: it names the files that implement it,
and naming a file claims implementation, which is only defensible once those files are on the
owning repositories' main branches. It becomes implemented when mesh-controller #63 and
mesh-catalog #69 land.
0112, 0113 and 0114 stay proposed; to-be 27 stays proposed with them.
The glossary's authority page still named the controller's seat the-controller in two
entries, contradicting its own seat section after ADR 0079; issue 058's heading kept the
pre-renumber 059; 055's fixed-by named branches that stop existing after merge (now merge
commits/PRs) and its located-in listed file paths where the convention wants repos; 056's
located-in named mesh-host, which received no fix, instead of mesh-catalog; and the design
layer never said the one-store/one-broker property is enforced — 07-the-foundation and the
installation table now state the seats.

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.

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.

Locks the vocabulary that kept drifting in conversation — controller (not
"control plane"), foundation (not "substrate"), node and control-node, seat /
bench / claim, package vs artifact. AGENTS.md points at it as the authority.
