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.

"control plane" -> controller and "substrate" -> foundation throughout
03-DESIGN, 00-META and the README, with 06-the-control-plane.md and
07-the-substrate.md renamed to 06-the-controller.md and 07-the-foundation.md.
The immutable 02-DECISIONS records keep their original wording (and links to
them are unchanged) — a term retired here may still appear there, which the
glossary explains how to read.

Assumed throughout and stated nowhere — the wrong way round for the most
consequential fact about this component.
A board reachable only over the private network would sit inside the
boundary 0004 already calls the security boundary, and a login there
would guard a room whose door is inside the building. This one faces the
internet, so its login is a perimeter rather than defence in depth.
Which makes the identity provider the mesh's outermost gate. The board
presents the control plane, and the control plane's networked surfaces
can change the mesh (0035) — so whoever that provider admits can assign
modules, from anywhere. Written flatly because it is easy to arrive at
one reasonable step at a time and then be surprised by.
What follows is not the board's own design: who may log in is a decision
about the mesh rather than about an application; a public name needs a
certificate from an authority the world trusts, which is why that work
exists; and the provider going wrong in the permissive direction is a
mesh-wide exposure with no local symptom.
The command line is unaffected and is why this is tolerable — it
authenticates through nothing and answers to the machine's own login, so
the mesh stays operable by somebody standing at it whatever happens to
the gate. That is the property to protect if the rest is ever traded
away.
First pass of a design review, done by reading documents against code
and against a raised mesh rather than against each other. Every error
below was invisible to a proofread.
**Statuses were stale, and nothing checked them.** Ten to-be documents
said `designed` while naming working, lab-proven code — several with a
*What was built* or *Raised, and observed* section. Added a
`status-vs-code` check: naming a file is a claim that the file
implements this, so a document that points at one has stopped being
merely designed. It failed on all ten before it passed, per the rule
this folder sets for its own checks.
**The bundle carries three images, not two.** 07 reasoned about which
substrate services go in and overlooked that the control plane is in
there too — it is what the substrate exists to start, and there is
nothing to fetch it with yet. Counted, not deduced.
**The bootstrap uses four shapes, not six.** It listed `file` and
`directory`, which substrate-first-node.lock never asks for. The claim
that mattered — nothing is blocked on the host — was true either way,
which is why the wrong count survived.
**The eight capabilities were documented nowhere.** Implemented in
internal/profile/detectors.go and enumerated in no document, including
the one about the host that detects them. A vocabulary modules write
against, readable only by reading the code. Now written down, with the
seat/graphical-session distinction that is wrong in both directions if
collapsed.
**MinIO swept out of the to-be layer** per 0028.
The gate now fails on one thing left deliberately: ADR 0024 is
`proposed` while two documents rest on it and the feature it decides is
built and lab-proven. Accepting a decision is not mine to do.
One reading answered three ways, holding nothing and touching no context's
store — which is the constraint the whole document is about, and the thing the
board being replaced gets wrong.
A page nobody had thought to ask for turns out to be the one a person
opens first: what is not doing what it was told. Recorded with the order
that matters — broken, then quiet, then out of date — because a page
leading with the last would bury the first.
And refused stays distinct from failed all the way to the page. They are
fixed in different places, so one word for both sends half its readers to
the wrong one.
Two additions to the module-repository design, both from building it.
A build machine has its own credential and it is not a node's: read the
build queue, write the mesh exchange, nothing else. A node's queue
carries that node's declarations.
The answer goes through the exchange and never the default one, because
permission there is per exchange rather than per queue — anything allowed
to use it can publish into any node's queue. The price is that every
asker sees every result and filters by correlation, which is cheap
against a builder never needing that permission.
And every result is kept, failures included, because one that leaves no
trace is indistinguishable from a build nobody asked for. That is what a
builds view reads; the board page is corrected to say so.
A build is work, not state, and that is why it does not travel as a
declaration: as one it would either rebuild on every reconcile or carry
"and I already did this", which is state about an event rather than about
a machine. So it has its own queue and the answer comes back correlated.
Three properties recorded because they are decisions: acknowledge only
once the answer is away, one build at a time, and a failure is a result
rather than silence.
And the board page is corrected. A build result today is answered to
whoever asked and kept nowhere, so a builds view has nothing to read. A
record of past builds is the missing piece, not the builder.
Read from the board that exists. Eight sections; four are about work and
workers and are held back with that domain. The other four are the mesh
itself, and everything behind the main one already exists here — it is a
reader, not a second source of truth.
The constraint is the point of writing this down now. The existing board
is one service that reads every context's database, because that is the
shortest path to a page showing all of them at once. That is ADR 0008
violated by the one component with a reason to violate it, and the cost
is the same one the shared library has: a boundary nothing may cross is a
boundary that can move, and one thing crossing it is enough to freeze it.
So a board reads through interfaces and stores nothing. If a question is
slow, the answer belongs in the context that owns it, where everything
else asking gets it too.
