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).
D2 raised a resolver urgent on one query that timed out while its machine was
loaded, and its summary carried the resolver's address and socket text, so the
operator channel withheld the whole alert.
- D2 asks every question up to three times, all at once; a resolver that
answers nothing is held for the next run and raised urgent when two runs
in a row find it silent. A wrong answer is still raised at once.
- Findings a single look can be wrong about carry Confirm: raised on the
second look in a row, kept while open, never cleared-and-reraised. Used by
D2 silence, D3 (also asks discovery twice), D6 behind, D9, D13 unmeasured,
probe-failed of the doctor, and blind watchdog rows.
- Probe seat asks (D8, D13) are asked again when the bus brought no answer.
- Summaries name machines and say things in words; addresses, paths,
domains and raw errors move to the evidence (D2, D5, D8, D9, D13, S12).
- internal/outward mirrors the messenger's content rule, allowing the mesh's
machine names; the keeper rewords a summary that would be withheld and keeps
it whole in the evidence; a TestMain lint fails the suite on any raised or
linted finding that would be withheld.
The night's backup of the bus takes each stream through JetStream's snapshot
API, run by the nats module under its own account. The module holding
mesh-broker is composed that account: stream names and info, the snapshot
request, its flow-control acks, its own inbox — no write, which the writers
table checks. A bus module declaring anything else to say on the bus is
refused by module check rather than silently granted nothing. The genesis
user list is unchanged: the controller's grants are.
Between assign and push a module's own secrets are not made yet; D1 composed
without making them and raised an urgent 'nothing can be sent' that the next
push resolved silently. D1 now composes as the push would (Foreseeing): a
secret the push makes gets a stand-in and is named, one the push is refused on
is refused with the push's words. Waiting is said only past 30 minutes, as a
warning. D3 and D13 expect a holder only once its machine was sent it and
reported or had ten minutes to.
A walk over a large library every hour loads the array that protects it. An item now says how it
is measured — a bounded daily walk, a dataset's counters, or its top level only — and a size that
is a lower bound is kept as such and never read as a shrink.
A module's data section says what it keeps and how precious it is; the backup holder's lines,
binding stickiness, retirement on unassign and D13's conditions follow from it, so issue 273's
empty replacement is said and an unassigned module's data is remembered, not forgotten.
grantsFor granted every consumer a pair credential from the provider was
ever made for, so a consumer pinned back to its own store was still asked
of the store it left, which then never retired it. A credential whose
consumer's resolution binds it elsewhere is now withdrawn like one nobody
asks for, kept on record for the login the provider keeps, and said on
plan and push.
Issue 258's fix let a mesh seat's holder elsewhere answer before this machine's own provider. Right
for the resolver, which any provider answers alike; for the store's seat it re-bound every database
consumer on a machine running its own store to the holder on another, each was given a fresh, empty
database there, and nothing said so for twenty hours.
- An offer says whether it keeps its consumers' data (`keeps-consumer-data`); unsaid, a provider
that grants each consumer a credential does. For such a provision the seat's holder no longer
overrules a provider beside the consumer; a pin still does.
- Where each such consumer was sent is recorded (migration 0071). A resolution that would bind it
elsewhere keeps the recorded provider and says the move; one whose provider is gone is refused,
never answered by another.
- A push says a kept move and raises it as an urgent condition at once; the self-check's D12 raises
it every run, with a pinned move not yet sent as a warning and any unasked move as urgent.
networking required mesh-wireguard and nothing else; machines are assigned the network directly.
module forget refuses a provided module, so a retired one is removed at start once no machine has it.
Guard route-proxy's public account directory against a reissue.
A provider that cannot disable keeps the consumer reachable until a person
deletes it (hq ADR 0230); the listing and the approval say so instead of
claiming access was disabled.
A provider now waits for a person before retiring more than three consumers
or half of what it holds, and deletes only when asked. The controller is that
person's way in: it keeps waiting and rejected sets as conditions, answers them
with retire approve|reject, lists and deletes retired consumers through the
provider's own tools on its machine, records each act in the hand-act log, and
probes for anything retired longer than thirty days (D11).
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.
Two controllers could both act (issue 204), a reconcile's report could
overtake the apply after it and the digest decided (issue 267), and a grant
could make a second writer of a machine's report.
- The lease (internal/lease, ADR 0229): mesh-controller_lease key `holder`,
15 s age, renewed every 5 s by compare-and-set; the epoch is the revision
it was taken at. The gate is the clock (stops 3 s before expiry); a refused
renewal is a loss and the process exits; a holder that stops gives it back.
serve takes it before asserting the bus. Epochs kept in the store
(migration 0068 controller_epoch) as a floor: a bucket raised from nothing
is compacted past it. Unleased (no epoch, S12 urgent) only when nobody
holds it and the bus will not let it be written. A shell command acts
under the holder's epoch, or its own lease when none.
- Declarations carry `epoch` inside the signed envelope, only to a machine
whose latest account carried a report_sequence (mesh-host #35); would-send
is composed with the epoch last sent. Allot and the send both pass the gate.
- Reports: contract in internal/link/order.go (epoch, sequence,
report_sequence, older_than, refused_older). Accounts kept by epoch, then
sequence, then report sequence; older refused, counted; unordered reports
keep the digest rule. Plans by compare-and-set on a revision, with epoch.
Conditions and calls carry the epoch and are not written off the lease.
- S12 and S13 (naming the writer by epoch) watched, D5 run; reset of the
bucket said. Writers table compiled in and enforced in PermissionsFor; the
controller no longer publishes mesh.control.>. A contract per consumed
kind, and the empty-on-error lint over the repository.
- mesh-host pinned to its main with the epoch in the validator (D1 validates
the envelope as sent).

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.
Live on 2026-10-06, two of the first self-check's findings were its own:
- D8 asked every machine's node-intrusion-prevention.banned, and the
controller's grant did not name the subject: the bus refused it 24 times
and D8 timed out after thirty seconds instead of saying so. The verbs the
self-check asks are named in broker.VerbsTheSelfCheckAsks and granted
(mesh.seat.<seat>.tool.<verb>.*); each probe declares the seat verbs it
calls, askSeatTool refuses an undeclared one, and a test over the
registry fails a probe whose question the controller is not granted.
AskSeatTool now returns a refused publish at once ("the bus refused…")
instead of waiting out its timeout; D8 asks the machines in parallel.
- D10 read every machine as behind right after a push: a node-engine says
its version as the directory it is delivered into, the archive's digest
(31045596c83a, catalogue versionOf), and D10 compared that with the
build's commit (1545b00a). It now compares with the versions the
registered build is delivered as, and a hand-placed engine's commit.
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.
A cancel writes the ask's id into the seat's cancelled set before deleting
the ask, and a write is a publish to the bucket's subject, which the
controller was not granted: against a server holding exactly the
controller's composed list, every cancel timed out.
A controller restart lost every call's outcome, `status` composed the mesh
while its caller waited (18.6s live on 2026-10-06, past the 10s window), a
repair by hand left no trace, and the core's bounds had nothing measured to
be set from.
- calls: kept in the controller's bucket mesh-controller_calls (last 1000 or
14 days, answers bounded to 64 KiB), read by id across a restart; a
controller starting marks a stopped one's running calls abandoned; each
call names its caller from the inbox its answer goes to.
- status: the serving controller composes it at start, after news from a
machine, a build or an acting verb, and every minute; the verb answers the
last composition at once with when and how long it took. Composing resolves
each machine once instead of twice.
- hand-act log in mesh-controller_hand-acts: push (required through the seat),
plans stop/close, broker consumer-reset and the new hand-act record take
--why/--cause/--condition; `hand-acts` lists them and repeated causes;
status counts the week's.
- durations (migration 0066): apply (send to first report), heartbeat gap,
plan tier and build, recorded as heard; `durations` summarises them.
- the controller's seat row takes this binary's definition of its own verbs,
so the console no longer judges calls against an older build's schema.
- the controller is granted its two buckets' subjects.
The one global 20-character bound made every consumer pay an object
store's key length, even for provisions that keep no name, and a single
overflow refused the provider's whole declaration. An offer now states
its own bound (identity: {max, in} or false); unsaid, a provider told its
consumers keeps 20 and one told nothing keeps none. module check judges
every identity on the longest machine name before merge, and a provider
leaves an overflowing consumer out of its grants and composes, with the
consumer named by push, plan and status (ADR 0225).
A machine runs many consumers of one provision, each with its own
credential. When one module leaks its credential, `rotate <provision>
--consumer <machine>` was the narrowest act and replaced every module's
on that machine, restarting all of them. --module (and the verb's
module argument beside provision) rotates only that module's.
The last report stored per node decides whether a release plan moves on,
and it was whichever arrived last. A report about a declaration the mesh
has moved past now records what it says about the machine but leaves the
account of the apply alone, so arrival order cannot undo the newer.
The controller acted only on what its events consumer handed it, so a merge
the bus skipped left modules behind with nothing said. The stream is now read
back every five minutes on a single-filter consumer, and any merge that would
still move a module after ten minutes is said and acted on.
A push outlasted the console's 30s wait and, when it sent the bus its
changed user list, the broker's reload forgot the reply it may send:
the push happened and its caller was told it did not answer. Calls now
answer in full or as running with an id, a push answers before it
sends, refused answers are recorded on their call, and 'calls' reads
them back.
A push naming one machine reached the verb without it and pushed every
machine behind (hq issue 244). The controller now refuses any argument a
verb does not declare, any it composed its command line without, and a
switch that is not true or false; a push that names no machine says first
that it is the whole mesh. Tests walk every served verb: no argument is
ever ignored, and every flag of a verb's command, read from the source, is
in its schema or accounted for. plan gains files, push behind, builds and
plans limit.
The identity provider failed every consumer for a day and status called the
mesh well (hq issue 179). The controller now follows every provider's
provisioner.failing/recovered, keeps the newest failing word per provider,
machine and consumer (migration 0065), and status, its JSON and node show
name it until it recovers. Every module that receives contributions is
granted the two events, so no manifest can forget them.
The seat now covers /etc/hostname too. The migration keeps the old name as
an alias so hosts, still assigned while machines move, holds the same seat.
Claims were compared by spelling, so the old and new module would both have
held it on one machine; they are now compared by the seat they resolve to.
The uplink's holder writes /etc/resolv.conf, so the seat that wrote it and
ADR 0220's dependency of it on the uplink have nothing left to say. The
migration deletes the store's row; nothing holds it once resolv-conf is
unassigned everywhere.
The catalogue moves /etc/resolv.conf from resolv-conf to the three uplink
modules. A rendered fact was not compared with other modules' paths, so two
modules could each write the resolver file on one machine, the last winning
every apply; a fact's path now counts as its module's.
musl takes the first reply from any listed nameserver, so a public fallback
beside the mesh's resolver answered NXDOMAIN for mesh names in every Alpine
container (hq ADR 0223). The fix is two mesh resolvers and no public one, which
needs mesh-dns-resolver held on two machines: a seat can now be replicated,
each holder recorded by 'seat <name> --add', checkClaims accepts every holder
on record and still refuses a second holder of any other mesh seat, a holder
answers its own requirement, and a roster fact gives each replicated seat's
holders, this machine first, so resolv-conf can list them. Migration 0062 keys
a holding by seat and assignment.
A named push flushed every other machine whose declaration differed from
what it was last sent (hq ADR 0083). Under an upgrade policy of `record`,
or a plan still waiting on its first machine (ADR 0218), every machine
running the module differs, so `push <one>` sent the held build to all of
them (hq issue 259).
Each send now records which build of each module it carried
(node.sent_builds, migration 0061). The cascade, and the bus holder added
to a named push, skip a machine any of whose modules would move to a
build its policy records or an open plan has not sent it, and say which
module, which build, why, and that `push <node>` sends it. A machine
whose last send was not recorded is held until it is named. The named
machine itself, a whole-mesh push and `push --behind` are unchanged.
daemon.json and docker.service belong to the docker module, which holds node-container-runtime
and now states the registry itself through ${seat:mesh-artifact-store:reach} (hq ADR 0222). The
overlay stops generating registry-trust and registry-trust-reload. A generated resource is now
held to the collision check every module is, so a second writer cannot come back through
computed code; resolution never saw what a generator declares.
The container runtime's module must state the mesh's registry to the runtime it owns, so the
controller can stop writing that into the runtime's file (hq issue 190). ${seat:<seat>:reach}
answers host:port without a binding: nothing required, granted or minted, and the address is
one the mesh already composes into every reference it built. Only mesh-artifact-store is
answered; another seat is refused by name. Unanswered in a file written into as JSON, the empty
member is dropped, so the runtime is never told to trust "".
Nothing has claimed node-dns-resolver since the mesh moved to one resolver
(hq ADR 0194); seeding never removes a row, so a migration deletes it.
resolv.conf stays the mesh's only while the network manager is told to keep
off it, which the node-uplink holder does (ADR 0117). A seat's Needs makes
that a dependency checked at assignment by the ADR 0207 mechanism (hq ADR
0220). The two-claimants test keeps its intent with a synthetic module now
that resolved-split-dns leaves the catalogue.
/etc/hosts is the file of the node-hosts-file seat's holder; the controller writes into no file
another seat's holder owns, and asks that holder if it ever needs a line there. The private
network's module stops asking for the node-names fact; every machine already asks the mesh's
one resolver for these names, and the host gives the region back at the next push.
A mesh-wide provision a machine could answer itself was bound to the local provider, with the
seat's holder and any pin consulted only for a provider on another machine. With every machine
still running its own resolver, each bound its resolver configuration to itself while the mesh's
one resolver was held and pinned elsewhere.
The catalogue moves daemon.json's live-restore and the reload from resolv-conf to the docker
module, so no module writes another software's configuration. The test composes docker beside
the resolver modules and refuses resolv-conf writing the runtime's file.
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.
