Every module named its events the way the old bus spelled a routing key, so on the
new bus every cross-module subscription pointed at a namespace nobody publishes to.
Nothing failed — the services started and none of them reacted. Converted, and the
rule now has checks at both scales: at registration for one manifest, and as a test
across the whole catalogue where a consumed event's emitter is present.
It was larger than the report said, in two directions nobody had looked. Forty-three
files of module code pass the event name at runtime, so the code mattered as much as
the manifests. And both clients had to learn the mapping — without that, converting
the modules would have broken the mesh that is actually running, which is the
opposite of what fixing this was for.
Design 29 gained three things it did not say: what a wildcard is (`*` for one name,
`**` for the rest, spelled the mesh's way and derived to each bus's own), that an
event about a role belongs on the seat and why that is not yet possible, and how the
rule is checked — because "a subscription that matches nothing is silence" is exactly
why nobody noticed thirty-seven manifests being wrong the same way.
4.2 and 4.3 are unblocked. The catch-up half of 4.5 is not: it is a decision, and it
narrowed rather than closed. It cannot be a reply to a module's inbox, because that
needs the blanket grant design 25 §4 refuses.
