AMQP is not a provision: the bus seat delivers the bus, and the word is refused #92

Two halves of hq ADR 0131. Pairs with mesh-catalog#120.

Migration 0040 moves the mesh-broker row from amqp to mesh-bus, so the seat's holder answers for the mesh's bus and not for the wire protocol the old broker spoke — which is what let only the retiring broker hold the seat that names the bus. Safe under the current holder: the control plane composes its own address through the seat by name and the overview derives holders by name; only registration and provision resolution read the column. What must not happen in between is re-registering the current holder — registration would now refuse it, by design.

The parser refuses a manifest that provides or requires amqp, each refusal saying what to do instead: a module reaches the mesh's bus through the sdk and depends on the seat, not on a protocol. A whole-catalogue test asserts nothing beside this checkout names it.

Two tests that used the old broker as a fixture now use the module that replaces it or a manifest this package owns. Catalogue, command and store packages green.

Two halves of novox/hq ADR 0131. Migration 0040 moves the mesh-broker row from
`amqp` to `mesh-bus`, so the seat's holder answers for the mesh's bus and not for
the wire protocol the old broker spoke — which is what let only the retiring
broker hold the seat that names the bus. Safe under the current holder: the
control plane composes its own address through the seat by name and the overview
derives holders by name; only registration and provision resolution read the
column. What must not happen in between is re-registering the current holder.

And the parser refuses a manifest that provides or requires `amqp`, each refusal
saying what to do instead: a module reaches the mesh's bus through the sdk and
depends on the seat, not on a protocol. A whole-catalogue test asserts nothing
beside this checkout names it; the three modules that did are removed there.

Two tests that used the old broker as a fixture now use the module that replaces
it or a manifest this package owns.
