mesh/merge-gate pass: builds mesh-host → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
A container that crash-looped after its compose applied passed every check the
gate had: nothing looked at what a module runs. The node-engine now judges every
long-running resource on every look — one read of the runtime, one per service
manager — keeps the restarts it counts across recreates and its own restarts,
and says the state in every report and as an event on change, again every minute
while not healthy. It reads only; nothing is restarted for being unhealthy.
The mesh runs on the seat's bus alone (novox/hq ADR 0131, design 28 task 5.5). The host's old
dialling and enrolment paths are deleted with the switch that chose between them; a membership or
a token naming another bus is refused before anything is sent, rather than dialled on a transport
that no longer exists.
Step 3.5's first half, mirroring the controller's. A host says exactly two
things unprompted, and the difference between them is the whole interface:
a report must arrive, and a heartbeat must not be insisted on. So a report
goes through JetStream — it is the message the store-window guarantee is
about — and a heartbeat stays on core, because a heartbeat in a stream is
the mesh's least valuable message competing for retention with its most
valuable.
The host still imports nothing of the mesh's own (ADR 0005): this is its
own interface over its own libraries. It agrees with the controller because
a fixture holds both to one envelope, which is the only agreement that
survives two repositories.
Also recorded, where the next person reads it rather than in a plan: the
"newest wins" window narrows at the rollout and does not disappear. Last-
per-subject makes the catch-up half the stream's, and sequence orders them
definitively — but three pushes to a connected node are still three
deliveries. Saying which half goes is worth more than "can probably be
removed", which is how a load-bearing window gets deleted in a hurry.
