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.

Closes the last open question about what the substrate contains. 0006
left an identity provider conditional — substrate only if the control
plane delegated authentication — and said the decision had not been
taken. It is now: it delegates to nothing.
The conditional was never about machines. A node proves itself with a
keypair it generated over a broker account issued at enrolment, and
declarations are verified by signature; none of that involves an
identity provider. It was only ever about whether a person signing in to
a mesh surface would be authenticated by something else.
So the substrate is three — a relational store, a message bus, an image
registry — and with 0028 having removed the object store, no member is
conditional and every one is there for the same reason.
It does not settle how a person signs in to a surface, deliberately.
What is settled is that whatever answers that is not something which
must exist before the mesh does, so it can be decided late or replaced —
which being substrate would have prevented.
