ADR 0483: the controller keeps a key per plan in its build phase; holders read it and
take no new check while one is there, but for the oldest check past 30 minutes, one
at a time by a let-through key. The queue says why checks wait.

A rebuild that landed while a walk waited for mesh-delivery's word was taken as
the walk's build of that module; once let go, the walk asked a tier only when
every module of it was unasked, so it never asked the rest and stood still.
A walk now takes only the outcomes of builds it asked, and none while it waits;
a rebuild does not join a waiting walk and says it runs beside it; and a tier
asked in part is asked the rest, including a module held built that the walk
never asked for, which is somebody else's build and not sent as the walk's.

A check judges one head; once the pull request has another, its verdict
answers nobody and its run holds a build machine the new head waits
behind. Asking a check of R#N at H now drops every waiting check of R#N
at another head and kills every one in flight, saying each in the log.
Announcements are unordered and a recheck asks a recorded head, so this
happens only when the forge confirms H is the pull request's current
head; otherwise nothing ends and that is said. A one-shot recheck ends
them within the call. Tries, walk builds, group checks, other pull
requests' checks and rechecks of the same head are left alone.

The forge clips a status to 140 characters, so the long sentence pushed the
verdict's own words out; and a paused holder's hand-back or a bus delay also
count as a delivery, so the cause is not claimed (novox/hq issue 594).
A build agent replaced mid-build leaves its ask to be handed out again, and
the second run looked like a first: the queue and the pull request showed
nothing of the 5-8 minutes lost (novox/hq issue 594).
Review of #276: a move deleted before it published, so a failed publish
lost an ask; a verb's own process ran a pass beside the serving one, so
one could resume the queue while the other moved asks and a build ran
twice. The copy is now published first and second copies removed by id,
asks only signal the acting controller's loop, moves stop with 5 s of
the pause left, a cancel finds a moved ask by id, and an unreadable ask
keeps its age.
A merged change's walk waited minutes on its build behind checks in a
first-come queue. The queue now hands deliveries out first, a check that
has waited ten minutes before deliveries asked after it, and says each
ask's kind; the order is kept in the work queue itself.
mesh/merge-gate pass: builds build-agent, mesh-controller → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without …
The queue verb answered only a table, so nothing outside the controller
could say an ask's place in the queue. It now asks its command for JSON:
each ask's state, kind, repository, commit, machine, since and position
among the waiting, with the table carried beside it and answered as the
verb's output, both written from one read. A repository's password, if
one were ever written into it, is left out of what is shown.
novox/hq issue 455
Each verb ran as a process that dialled the bus, so hundreds of short
connections an hour, all named mesh-controller, hid any client reconnecting
in a loop (hq issue 327). D15 now says a user whose connections keep dropping.
Review of #150: a withdrawal could land between the look and the act, a
failed ask read as a build in flight, a request kept the wrong asker, a
build being registered read as not built, build "true" could ask a build
nothing waited on, and a status read changed state. Claim a row under the
machine's hold before making it, keep a request only once asked, settle on
the controller's own tick, raise an assignment not made as a condition
until it is answered, and tie each row to its machine.
A registered replay asked now outranked newer asks of its module, and a plan
took any later outcome as its answer. A replay is now refused while the module
is asked anywhere, a plan module asked under an id is answered by that id
alone, and a rebuild of a commit asks what the module follows. An ask handed
back after a restart no longer reads as dead; a cancel that meets a start is
withdrawn; pause holds for an ask fetched as it lands; kill removes containers
before and after the build ends and says whether its outcome went out; a
holder may say only its own machine is paused.
Nothing showed what waited for a build machine, and an ask could not be
dropped without leaving the plan that made it waiting for ever. New verbs:
queue, cancel, clear, rebuild, replay, kill, pause, resume, and plans retry.
Every ask a person drops is recorded failed through the same take-in as a
failed build; a plan keeps the id it asked each module under and matches
its outcome by it. replay is a dry run unless registered, and registering
an older commit than one registered since needs --older (hq issue 207).
A plan waiting on a seat paused on every holder says so and is not late;
a failed plan can be retried, and a rebuild joins the plan holding the
module instead of running beside it.
