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.

A new batch beside the open one walked an older commit after a newer one, and a
stop that failed partway could leave a merge on two plans. A module shared with
the stopped merge, built at its branch, would deliver it; it is left out or
withheld. A batch not yet cut can drop a merge, so mesh-delivery can stop a
merge walked again. The stopped walk names what it left on which machines.

The operator's budget (a leaf module running everywhere within five minutes
of its merge, a core module within ten) cannot be held to without knowing
where a walk's time goes. A walk now keeps when its batch's window closed,
when it was cut and its class (migration 0093), each gate reading, and what
each machine of the rest was sent; 'delivery walks' and plan-moved say its
phases from the merge to every machine of the rest reporting the build
applied, and ended walks keep them as walk-phase durations per class. Probe
D16 reads mesh-delivery's 'times' and raises delivery.<class>.over-budget.
A phase that cannot be measured is said unknown, never zero. Measurement
only: no walk is held, sent or judged differently.

Every merge opened a walk and the next merge of the branch superseded it: two
catalogue merges 18 s apart left a walk no delivery held, and the operator
started it by hand 58 minutes later. A merge now joins the open batch, kept in
the store (migration 0089), which is cut into one walk when no merge came for
merge-window (90 s) or at merge-window-at-most (10 min): one commit per
repository, the latest of its branch, with every file the batch's merges
changed. One walk at a time; a started walk is never superseded, a waiting one
is folded into the next. The walk names every merge it answers on the wire
(delivery.merges, taken_over_by, batch). A failed walk walks its earlier merges
alone, newest first, until one is delivered. A delivery group's order becomes
tier edges inside the walk. plans shows the batch assembling; S18 and S19
bound its waits; S16 names the merges a waiting walk answers.
