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…
mesh/delivery-group group feat/health-the-field rejected: its order contradicts itself: novox/mesh-controller@468d509462fe, novox/mesh-host@96bf9415aae4
A module could say nothing about what ready means for what it runs, so a web
application with its port open and its requests hanging passed everything for
eleven hours (issue 145). A long-running resource now carries `health` — the
image's own check adopted by name, http, tcp, exec, unit or a module's own tool,
with its timing — refused near its author when it names a port or an address,
an endpoint the module does not declare, a tool it does not serve, a tool check
alone, or a timing outside the record's bounds. It is composed with the endpoint
as the port this machine published it on, and sent only to a node-engine whose
statement says it reads it: an older one would refuse the whole declaration.
The engine is granted its own machine's instance of each health tool. `module
check` warns of every long-running resource without `health`, counts them for
the catalogue, and refuses them from 2026-11-18. A check's findings stay out of
a condition's summary. The node-engine's validator is vendored at its Phase B
commit, so what is composed is judged by the words the engine takes.
The gate judged a module by what the mesh saw from outside, so a container that
crash-looped after it applied passed it. Each machine's node-engine now states
the health of every long-running resource it runs; the controller keeps the
newest statement per machine, raises module.<module>.<machine>.unhealthy on the
second statement in a row, clears it on the first that does not say it, and the
gate passes a module only when every long-running resource of it is stated
healthy since the send. An engine that states nothing is judged as before.
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…
The gate composed 0 of 4 machines with the change and without, and passed every change: the store it
raised held each module's bus credential but no account for it (issue 203's refusal), no outward links
(so no filter could be composed), and refused settings the mesh holds. Now the account is minted with
its credential, the facts carry each machine's outward links (a stand-in for an older snapshot), the
mesh's layers are kept as held, and a withheld path keeps a path's shape. A machine the mesh composes
that the gate cannot raise makes the verdict an error, never a pass; the verdict alone is on stdout.
A merge-check.sh that passed on an agent's machine failed on the build seat: a newer gofmt, siblings at
a feature branch, another user. `mesh-controller check-here` runs builder.Check with the ask the
controller would make, from facts that now name the toolchains and the refs cloned beside; a failed
script is said by what failed. (novox/hq issues 282, 283)
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.

An image is not byte-reproducible, so ADR 0236's 'same artifacts is no move'
never held for one: a catalogue merge that did not touch the bus rebuilt it,
and every send to the control node waited for a planned bus upgrade.
The builder now records a source fingerprint per build (module tree, context
trees, bases and toolchains by digest). A rebuild with the fingerprint of the
build it repeats is registered with that build's artifacts, handed to modules
standing on it, holds no push, demands no bus step, and a plan sends and
gates nothing for it. Identical artifacts remain a second way to be no move.
The live tests reached one shared bus and assert, read and remove the mesh's own objects by
their fixed names, so packages run in parallel deleted what each other read and the suite
passed only one package at a time; a red suite read as noise. internal/testbus starts a server
per test, linked in at the nats-server release go.mod pins, and a test holds that pin to the
catalogue's bus image and to the facts snapshot's bus when there is one, so the tests never run
a bus the mesh does not. The waiter test read a timing (the most connections held at one look)
and now reads the state it means (the fewest held across the wait). make check runs the packages
in parallel under the race detector, with a timeout.
Every check the mesh had was right about the world it was given and none was given
the mesh's: a real machine's name made an identity too long (263), the node-engine
refused what the catalogue check passed (236). The controller now composes what a
check needs - every machine under a pseudonym of its name's length, its roles,
system, builds, capabilities, assignments, pins, settings and how its declaration
composes; every seat, module and source; the bus, store and node-engine versions it
runs - with no secret, no address and no name, and keeps it in the artifact store
as facts:latest when it moved, or daily. The replaced snapshot's manifest is let go
of, so the nightly collector takes it. S14 raises facts-stale past two days.
The merge of mesh-catalog 7f99fb4a rebuilt 103 modules with the build agent in tier 0, and ADR
0236 recorded it as "a change to the build agent rebuilds most of the catalogue". The agent had
not changed: modules/showcase/index.ts had. showcase is the catalogue's reference module, held
by no machine, and its manifest was not in the merge, so whatTheMergeTouched read the file as
shared code and rebuilt everything built from the repository (88 came out byte-identical). The
agent stood first only because everything is built by it.
Whether a directory is a module is a fact of the repository at the merge commit, so the forge's
announcer now says it: module_dirs, the changed files' directories holding a module.json there,
with module_dirs_said. A changed file inside one is that module's business; only a file in no
such directory is shared. An announcer that does not say keeps the old rule. `plans` what-if
takes the same list as module-dirs.
And a regression for the open question: nothing depends on the build agent except by being
built by it, and built-by never widens a plan, so a change to the agent - manifest or program -
rebuilds the agent alone; what moved beside it is ordered after it.
A send carries the machine's whole declaration, so at the switch to roll the next send of
anything would have carried the old default's backlog, unjudged, to every machine. A gated
send now carries and judges everything waiting on its machine; every other send is refused
or leaves the machine; a release plan walks what waits one machine at a time, the control
node last, and one that fails holds the next until a person releases it.
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).
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.
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.
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).
Needs mesh-host's genesis lock with the lease grant (mesh-host PR) for
TestTheInstallersFirstUserListIsWhatTheControllerWouldCompose.
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.
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 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 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.
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.
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.
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.
Grants first could hold back the very declaration that lets the controller
issue them. The holder now goes first, then buckets and memberships, then
the rest; a membership that fails holds back only its own machine, and an
announcement whose send stopped at its grants is asked again. Whether the
holder must go first is read from a digest of the user list it was last
sent, not its whole declaration. Migration renumbered to 0058.
A merge planned without looking at open plans, so two plans worked the
same modules and a stuck plan stayed open for ever. The newer plan folds
in what older plans of the same repository and branch had not built or
sent, and closes them as superseded. A person can close a stuck plan by
id with `plans close <id>`.
A plan sent every machine running a module at once, ignoring the module's
upgrade policy. Unless the policy says together, the first machine by name
is sent, recorded in the plan, and the rest follow only once its report
after the send says it applied; a failed first machine stops the plan.
The store's garbage-collect marks only from manifests, and archives were
published as bare blobs, so the first real collection would delete every
archive the mesh keeps. PublishArchive now puts a deterministic OCI holder
manifest (empty config, one layer) beside each archive; the sweep holds every
kept archive before it lets anything go, which backfills existing bare blobs,
and lets go of an archive holder-first. A forgotten module no longer keeps its
five recent builds (ADR 0189). `collection [--json]` reports kept archives
held/unheld and what may be let go, so the dry run can be lifted on evidence.
The postgres-backed test still expected a module that declares no broker
secret to be a bus user, and failed on main since #270; it skips without a
database, so the change's own run did not see it.
Every assigned module was composed as a bus user, though only one declaring
a broker secret can ever be issued an account; the rest were named on every
status, plan and push as credentials never minted (137 now), burying the
real gaps. Their durable consumers are now derived from what the runtime
carries, so nothing they hear changes. The composed file is unchanged:
those users had no password and were already left out. Fixes hq issue 195.
Issue 225. The mesh seals one credential per consumer beside the provider's
contributions file, and wrote it root-owned. That was right while a module's
own code ran in a container as root; ADR 0198 moved that code under the node's
runtime, as the node's account, and the secret stayed root's. On the control
machine two consumers went unprovisioned for three hours and the only sign
was a line reading 'secret not readable yet', 4330 times.
The same sentence is already written for a module's own secrets a few hundred
lines above — 'a root-owned 0600 file is one that process cannot read'. This
is that rule reaching the other kind of secret the mesh writes for a module.
Issue 226. The sweep met a reference recorded with the store's old address,
read 'I will not address this' as 'the store refuses everything', and
collected none of the 1681 it had found. Two changes: references from build
records are read through Recorded, where the provenance is known — not in
LetGo, which cannot tell one registry host from another and must stay strict
— and a reference the sweep will not address is now ErrNotOurs, skipped,
never a reason to stop. Only the store refusing ends a sweep.
make check: the two failures both fail on main as well — the resolver test
(hq 202/203) and the service-manager test, which reads this machine's own
shell environment.
The bundles refactor took ADR 0188 on main, so this work's record is 0201 and
every comment citing it moves with it. Main also took migration 0055 (an
older build never replaces a newer), so the store's collected-artifacts table
is 0056 — a number two migrations share is a schema nobody can trust.
make check passes except TestTheResolverIsToldEveryMachineOnTheNetworkAndToldAgainWhenOneLeaves,
which fails on main too and now for two stacked reasons (hq issues 203 and 202).
A manifest names the state it keeps (state) and reads (reads); the controller
asserts a key-value bucket per name on every raise, grants owners write and
readers read (measured against a running server), issues each assignment its
buckets in the membership, and reports buckets nothing declares without
removing them.
