While the mesh-delivery seat has a holder on record, a merge that moves no
core module opens its walk and asks nothing until mesh-delivery or a person
says go; nothing of it is registered before its turn, so no other send
carries it. The controller keeps the planner, the gate, sending and the
walk, and gains the verbs the owner asks with: delivery-plan, -order,
-check (a group composed as one future state), deliver, delivery-stop,
delivery-walks; every walk kept is said as plan-moved.
Every check the mesh had ran after a merge, on a machine: a manifest the node-engine refused
(236), an identity a real machine's name made too long (263). merge-gate raises the mesh as the
facts snapshot says it is and the mesh with the change, each in a throwaway store through the
controller's own records, composes every machine twice and validates it with the node-engine's
validator, and fails what the change breaks, naming the machine's roles and the module - plus a
manifest the judging controller cannot read, a consumer left out of its grant, a module removed
while a machine runs it, a new module the node-engine would refuse; it warns on a wide rebuild.
The forge's new head of a pull request becomes a check the controller asks of the build seat:
the head and, beside it, the controller the mesh runs, the catalogue, the host and the lab; a
throwaway store and bus of the versions the mesh runs; the repository's merge-check.sh in the
mesh's Go toolchain with no container runtime socket; then mesh-lab's replays. The verdict is
said as checked, an error never a pass, and nothing is recorded or registered.
A build that reported applied was sent everywhere; one that then did nothing, served
no tools or broke its machine's word reached every machine. Now the first machine is
judged by the component's health (the core's definitions, as doctor probes H-*, or a
module's own) three times over two minutes within ten; a failing gate puts the previous
build back there once, marks the build, and says it as a condition and an event.
Upgrades roll out by default; the bus is a planned step; a module deleted at its
source is not built (the public-acme plan failure).
Research 031 counted the repairs people made by hand: a push to unstick a
plan waiting on a report, a controller restarted to make an object again, a
plan closed, a consumer re-made from now. Each was the ordinary path taken
again by someone who noticed. The healer registry makes each a registered
response to one condition kind, with a budget, a settle and its event:
- H1 sent-not-reported: ask the machine's node-engine to report again
(mesh.node.<n>.ask.report); if it does not report what it was sent, send
it again, never moving a build a policy or a plan holds back
- H2 stalled: close a plan whose wait is superseded or finished
- H3 holder-silent / consumer-lost: the send's own assertion of the bus's
objects (issue 208's note)
- H4 consumer-behind: consumer-reset, only for a consumer the stream table
marks resettable (the controller's own events consumer)
- H5 is the identity provider's own repair (ADR 0224 §5), registered only
Success is the observation clearing the condition, never the healer; a spent
budget hands the condition to the operator, urgent, with what was tried, and
no healer touches it again. Every act is begun in the store before it is made
(migration 0070), kept in the condition's tried as "healer Hn" and said as
the seat event healer-acted; a heal is never a hand act. More than twelve acts
in an hour stop every healer until an hour after the last, said urgently.
Only the lease holder heals.
S15 is live: a cause repaired by hand twice in a fortnight raises
healer-wanted, naming the healer that was not enough where one exists. D6's
far-behind finding has its own kind, consumer-behind. Nodes are granted the
question; the controller's grant gains healer-acted (genesis lock in
mesh-host). `healers` lists the registry, the acts and the brake; status
counts the week's heals.
A given own secret the module reads at start is held by nobody but that
module, so the mesh need not read it to replace it: secret rotate now
works on it, and a value given through secret accept is replaced on its
own after the module's first good start under the mesh. Only a value an
outside party issues (own-secrets "issued-by": "outside") or one the
module applies stays as given, refused with the reason.
Every one of the 48 core failures of research 031 was found by a person
looking; the mesh's answers carried the fact for whoever asked and told
nobody.
- The condition store (to-be 45 §2): mesh-controller_conditions, one key
per open condition, written by compare-and-set so a person's silence
and the watchdogs never lose each other's word; every transition kept
ninety days in mesh-controller_condition-history and said as the
seat's events condition-raised / condition-changed / condition-cleared
(the condition at the top level, with event, at, change, why, show),
offered again while the bus is away. Raised and cleared by observation
only; a clearing reopened within ten minutes is the same condition with
its count up, its silence kept. Verbs: conditions, conditions show,
conditions silence (a hand act, at most a week), conditions history.
- ADR 0224's provider standing is the first kind, provider-failing, held
by the provider's events; the provider_standing table is no longer read
or written (left in place: dropping it is the operator's word).
- status leads with the open conditions, urgent first, and says all well
only with none open; conditions it cannot read are said and not well.
- The signals table compiled in, one watchdog loop over it every 30s: S1
heartbeat (3 intervals, asleep machines excepted, control node urgent
after 30 min), S2 report after a send, S3 plan tier, S4 event loop deaf,
S5 merge not acted, S6 ask lost, S7 call hung, S8 provider silent, S9
advisories, S10 self-check silent, S11 node tools silent, S13 stale
refusals; S12, S14, S15 deferred with their reasons. A row that cannot
see raises probe-failed and clears nothing. A test generated from the
table suppresses each signal inside and past its bound.
- The bus's advisories (maximum deliveries, a mesh consumer deleted) and
the controller's own slow consumer and refused subjects, said in the
mesh's words.
- doctor: the probe registry D1-D10 (D5 deferred) and DW, every five
minutes, each in thirty seconds; a probe that cannot run is never a
pass. D1 validates with mesh-host's own validator. Every run ends with
the doctor-heartbeat event mesh-watcher listens for.
- The controller is granted its new buckets, events, the two advisories
and $SRV.INFO; the node tools their tools-alive heartbeat. The streams
and consumers the controller asserts and the ones D6/D7 expect are one
derivation.
The grant permitted the control plane to state what it applied and the seat said nothing about it, so
the check that every derived subscription has an owner found the catalogue subscribing to a subject
nothing publishes — which is exactly the fault that check exists for, pointed at me.
A seat carries the protocol of its role (novox/hq ADR 0129), so the facts are the mesh-controller
seat's `emits`. That is also what lets another module declare it consumes them. No accepts, so no work
queue is raised for the seat — only what its holder may say. The agreement test now holds all three
places to one another: the seat, the grant, and the words the mesh states them with.
The pipeline was observable from a merge to an artifact and went dark where it touched a machine: a
node's report is control traffic only the control plane reads, so nothing said which version a
machine runs, or that it refused to (novox/hq ADR 0134). The control plane now states both under the
seat it holds — a role's events belong to the role and keep their address when the holder is
replaced — and only when the report is news, because a machine reconciles every minute and a fact per
report would be a fact per minute per machine.
Whether a report is news is the store's answer: it holds the previous one, so the listener returns it
and the server states the fact. That also gives the catch-up replay a subject the controller may
publish: it was published as a module's event from a module called "control-plane", which does not
exist, so the controller's own account refused it and every catalogue that asked what it missed was
answered with nothing.
