mesh/merge-gate pass: builds build-agent, mesh-controller, route-proxy → ace, g14, novox, shanks; no bus step; every machine composes with the change as it…
A merge's group member counted as merged when its merge waited in any batch,
but kinds never share a batch: the later member got a batch of its own, cut
at once, and walked before the earlier member's batch was cut, breaking the
group's order (ADR 0276 §5). Only a member kept in a batch of the merge's own
kind counts as merged now; one kept in the other kind's keeps the merge
waiting, and its batch names that member, so the two are cut in the order
their windows close (review of #250).
A merge from any head waited for the window because the controller could not
see a group's members, so the window skip changed nothing in production and
unrelated merges walked one after another. The controller now asks
mesh-delivery's groups, within 3 s and before the plans are held: a merge
waits only when its head's group has another member whose pull request is
open and whose merge it does not keep yet (ADR 0306 §2). No answer means it
waits, and its batch says why. A headed merge in no waiting group and related
to no batch is cut at once, as one from no head is (ADR 0304 §1, ADR 0306 §3).
The controller's grant names mesh-delivery.groups. The installer's first user
list in mesh-host must carry it too before the genesis test can pass.
A merge waited the whole window even when nothing assembling shared anything
with it. It now joins only a batch it is related to (ADR 0304 §1, read by ADR
0306 §3: repository, a module the cut would move, a graph edge, a group head),
folding the newer into the oldest when it relates to two. A merge related to
none starts a batch whose window is closed at once (PlanBatch.CutAtOnce),
unless its delivery group may still have a member to merge (ADR 0306 §2).
The controller cannot see a group's unmerged members (that is mesh-delivery's
record), so a merge from any head still waits, in a batch of its own: the safe
error is to wait. Walks stay one at a time; a batch cut at once queues behind
an open walk. A stop's merges walked again join a related batch, or their own.
