A build asked at a commit recorded that commit as the module's ref. Every merge after it failed to
match the module and its plan left it out without a word, and every plan that rebuilt it asked for
the same old commit again. Registration now keeps the branch the module followed (the default
branch for a new one); matching and re-asking read a recorded commit as the default branch, which
heals records already pinned this way; and a merge says which modules of its repository it leaves
out because they follow another branch.
Grants: a principal that serves tools subscribes $SRV.PING/$SRV.INFO and those questions under
each name it serves — its own and no other's; the tool runtime and people may ask. The controller
answers discovery for the mesh-controller seat in NATS's services format, one endpoint per verb it
serves, with the seat's description and schema. module list --json says which modules declare tools,
so the console expects an announcement only from those.
The console's discovery reads the machines and the modules; parsing a printed column breaks when it
is reworded. Both now answer JSON on --json, as status and seats do, and the seat verbs ask for it.
The roster published routed names — public ones first, then (in this PR's first take) internal ones
told apart by suffix. Neither is needed: a node has one internal domain and every route on it is a
name under it, answered by the resolver's per-node wildcard; a node's public domains are public
DNS's. routeNamesInTheMesh and NamesServed are removed, and a test pins .Names to the machines.
NamesServed read a route's public `name` and plan.go then filtered by suffix — telling the mesh's
names from public ones by their spelling, when the mesh composed both itself. It now publishes the
`internal-name` it composed under the serving node (ADR 0151); the suffix filter is gone.
Every routed public name was published into each machine's hosts region at its serving node's
private address. ace's resolver also answers its LAN, so a phone there got the control-node's
tunnel address for the mail server and could not connect. Routes have internal names under the
serving node (ADR 0151), so only names under the mesh suffix are published now.
A plan is ordered by artifacts and says nothing about what must be running before what (ADR 0162);
on 2026-10-03 that put the build machine in tier 0 and the controller in tier 1, and the new build
machine could not bind the worker the old controller had defined. One running order enters the
graph, named as its own edge: a module claiming the build seat follows the control plane, and the
built-by edge from the control plane to that holder yields to it — the controller is built by
whichever build machine is running, as the runtime image always was. The edge orders a plan and
never widens it, like built-by.
On 2026-10-02 a runtime assigned and applied on two machines was undone two seconds later by a
declaration that had the assignments of a minute earlier. Every path composes from the records at
compose time and holds the machines it sends — but the number went on at SEND time, after
composing, so a declaration composed before an assignment changed and sent after a newer one
carried the higher number, and the host, which rightly refuses a lower number, took the older
content as the mesh's newest word. The record of that send was never written either: it is written
after the declaration is away, on the sender's context, and the controller sending it was being
replaced in that very second — status read "applied, current" over a machine just told otherwise.
Now the number is taken before the composition reads anything, in every path, so what was composed
earlier is numbered lower however late it goes out and the host's refusal does what it is for; and
what was sent is written down on a context that outlives the sender, bounded, so a dying controller
still records what it told a machine. The `declare` command — a declaration a person sends by hand —
records its send too. Proven: compositions in one order and sends in the other keep the numbers in
composition order; a send is recorded after the sender's context is cancelled.
`assign` recorded a module and `push` sealed a random own secret where its bus credential belongs;
the process crash-looped until a person ran `module issue` and pushed again, and the only warning was
one line in a list printed on every push. Now assigning a module that declares a broker secret issues
the credential in the same act — kept when one exists, so re-assigning rotates nothing — and when the
bus cannot be reached from here the assignment says which verb to run. A push never seals a
placeholder in a credential's place: a module whose bus user is unminted is refused by name, with the
verb. The control plane's own user is the installer's, seeded at genesis, which the test now says.
And what reads one of a module's own secrets is restarted when it changes — composed for a container
or daemon that names the secret's path in its volumes, environment or env-files, so a manifest need
not say it: the build machine ran on an hour-old credential because its manifest restarted it on its
environment file alone (issue 206). A scheduled or run-once process is left alone; it reads afresh.
A controller that asked node-build-agent from its first run would queue every build where nothing
pulls, and the build that registers build-agent — the first holder — would be among them. So the
role is chosen at ask time from the catalogue: the current role when any assigned module claims it,
the retired one while only the builder does, the current one when neither. Outcomes are followed on
both seats, the controller may publish to both, and a build's log is read under whichever role did
it; a machine on the retired role is proven on the bus to take that role's asks. The switch order
is written where the role is named, and the retired half is marked for removal with the seat row.
After the build role moved to node-build-agent, nothing would hold it until build-agent is
registered — and registering build-agent needs a build outcome that only the running builder
could produce, bound as it was to the old seat by name. One binary, two roles: the seat a machine
serves is the first its credential claims, as the mesh writes the claims beside the credential it
issues (ADR 0159); the old builder keeps draining mesh-build-machine, a build-agent takes
node-build-agent, and what each says about a build goes out as that seat's events, so an outcome
is heard where the asker of that seat listens. A credential naming no claim serves the current role.
The controller widened the bus's from-mesh port to from-anywhere on the
broker's host so a machine could enrol before it had a tunnel. ADR 0169
has machines join through the tunnel and decides the bus is never public;
every live bus connection already comes from the mesh.
A module declaring tools, a container, and a build on mesh-tools' runtime image is a container whose
purpose is serving tools — the pattern the node's tool runtime retires. Once node-tools is in the
catalogue, registering one is refused by name, with the record that says why; before, it is accepted
as it always was, so a mesh converts in the design's order and nothing is refused before there is
anything to move to. This is the mechanism that keeps the old pattern from returning by habit.
Judged from a repository manifest's own build.on, and for a built manifest — which carries no build
— from what its build stood on, now recorded beside the commit as part of a module's provenance.
One verb in the row that this binary cannot run aborted the start, and a stale push that put an
older control plane back took the whole mesh off the bus for ten minutes — recoverable only by a
person running the binary outside its service, because the push that repairs it is one of the verbs
that had stopped being served. Now the verbs it knows are served, the ones it does not answer the
reason, and the start names them once.
Where the node-tools module is assigned, the machine's bus user list gains one principal of kind
node-tools in place of that module's own: it may subscribe every carried module's tool namespace
and every held seat's verbs on its node, read and follow every membership on its node, call any
tool anywhere, answer what it is asked — and consume nothing, because tools are what it runs.
Every other module keeps its own principal, so a module still serving tools from its container
holds its own credential until it moves.
Named exactly as the module it stands for, so `module issue` and `rollout mint` deliver its
credential through the path a module's already takes, into node-tools' own `broker` secret. The
runtime module's name is one constant in each of the broker and catalogue packages, held to one
string by the agreement test, because a rule turns on it.
Beside the named verbs, `command` takes a command line as the controller's
own shell would — `node account g14 jochen`, `node show ace`, `module list` —
splits it as a shell does (quotes group, backslash escapes, nothing expanded)
and runs it in this binary like every other verb. The named verbs keep their
schemas; this is the whole binary, added because the operator decided any
node may call any tool (hq ADR 0175) and a verb per command was the only
thing keeping the rest behind a shell on the control node. ADR 0154 carries
the dated note. Tests: a plain line, quoted words, an empty line and an
unclosed quote refused.
A host reports every table and chain that refuses traffic with its owner,
and a converged machine's found firewall's state. The controller keeps both
on the node's record (migration 0054), shows them on node show, names every
converged machine something other than the mesh filters in status — text
and JSON, and such a machine is not well — and the converge preview lists
what filters the machine with the fate of each: retired with the front end,
left as the runtime's, left as a ban, or left in force and not the mesh's.
What was invisible for eleven hours (issues 144, 145) is said by name.
Per-machine and mesh-wide settings could be set only from the
controller's command line. The settings verb runs settings set|clear,
passing the values inline, which the command now accepts as well as a
file (novox/hq issue 198).
take ends its preview with a digest and --yes names it, as the flip does; a
changed preview or an account older than the flip allows is refused. A module
the machine holds nothing for has nothing to compare, and --yes suffices. A
published port's reach is said as the machine reported it. Every secret the
module holds on the machine is listed with where it came from, and one the
mesh minted for a service whose data was found refuses unless --mint names it.
One judgement of a module's settings against its definition, in the catalogue:
settings set refuses what cannot compose or reaches nothing, naming node,
module, layer and key; Compose leaves out a module whose definition moved
under a stored setting, the envelope says so (left_out), plan and push say it
by name, and the machine is told everything else. A stray setting no longer
refuses the whole machine where it is read (issue 096).
The per-machine setting networks keeps a found network for a taken container,
on an adopted machine only; the container's declaration carries it and the
preview names it (rule 4).
A module's account was mintable only from the controller's command line,
so a rollout that gave a module one could not be finished through the
mesh's own tools (novox/hq issue 191). The issue verb runs module issue
for a module on a machine; the caller pushes the machine after.
The proxy answered every routed name to any request carrying it, so an
internal-only route would have been public under its internal name. Each
membership now carries what its module receives, from the same
composition as its received file, and every machine's private-network
address, the list the packet filter's "from the mesh" is. The proxy
follows its membership, serves internal names only to those machines and
itself, and keeps the file until the bus has spoken (novox/hq ADR 0167,
issue 191).
Given a repository and the files a branch changes (or the modules by name), plans answers with the tiers
the merge handler would produce — the modules those files touch, what packages their source, everything
reachable along the dependency relation — and what each tier does: built and sent to its machines, or
built and left because its policy records. Saved nowhere. On the seat as plans {repository, paths|modules}.
A dependent rebuilt because its base moved, or a module that packages another repository's source,
keeps its source commit; the catalogue announces no move for it, and its machines kept the old image
until somebody pushed — forty-three modules after every runtime-image merge (hq issue 189). When a tier
is built, the plan now sends the machines of every module in it whose policy rolls out, once, moved
commit or not; a module whose policy records is built and left, as its policy says. The gate between
tiers waits as before for the ones a later tier is built by.
A tier whose module a later tier is built by waited for the machines running it to report after the
build — and relied on the catalogue's moved event to send them. A rebuild from the same source commit is
not a move the catalogue announces: the build machine rebuilt for a controller change kept its commit,
nothing sent it, and the plan waited on a report that would never come (2026-10-01, 19:45Z). The plan
now sends the machines running a gated module once, records when, and waits for the reports after that.
node show printed what a machine reports only for an adopted one; a converged machine holds nothing
and can still run a container nobody asked for (hq ADR 0163), so its strays are said whatever its mode.
The host now reports, for every held thing, the facts a take compares; the controller keeps them, and
take puts them beside what the module declares — the found image and its age against the declared one,
the found networks and who else is on them, ports and mounts, a found file's difference from the
declared content — and refuses a downgrade without --downgrade and a differing file without --replace
<path>. Without --yes the comparison is printed and nothing is taken. node show lists the facts and
the strays the machine reports. build and the daemon's take-in say when a module's policy rolls the
result out at once. The own-secret refusal points at the provider form for a required secret.
With one machine excluded, the others are resolved without its offers, and one that consumes them
cannot resolve by design — the view is partial, the machine is not dropped. The line that names a
dropped machine now speaks only for the whole-mesh view (seats), where a drop is a fault (hq 188).
The second pass of theRestOfTheMesh resolved every machine without its pins. Since a machine with two
providers of one provision is refused unless a pin names one (195/196), the control node was refused
there and vanished: every seat it holds read as unheld, the build machine refused what needs the git
seat, the roll-out was refused — and nothing said why (hq issue 188). Each machine is now resolved as
its plan resolves it, with its pins; a machine left out is named with the resolver's words.
The first live plan took seventy-five modules along for a controller change: the builder packages the
controller's source, everything is built by the builder, so everything was reachable. A module built by
the build machine is not changed by a new build machine. Reachability now follows the code and build
edges only; built-by still orders a tier after the build machine and gates it on the machine's roll-out.
plans stop <id> ends a plan by hand: what was asked still builds and registers, nothing further is asked.
onTheNetwork resolves every machine unchecked and skipped one whose resolution refused. A machine
skipped there has no address, so its own plan fails on the first placeholder that needs one, in another
module's words, every seat held on it reads as unheld, and what is built from it cannot be built — four
symptoms, none naming the refusal (2026-10-01, the control node, forty minutes). The refusal is now said
where it happens, in the resolver's own words.
The mesh's seat answers plans — the recent plans with their tier, what each waits for and since when,
or one plan whole given its id — so the console reads a merge's progress where it reads everything
else, instead of a person reading the daemon's log.
A module's dependencies are one relation in the catalogue — stands-on, packages, built-by, declared —
answered by one call. A merge takes what moved and everything reachable from it, sorts the set into
tiers (a code dependency in the same tier, a build dependency after its base is built, a runtime
dependency after the build machine is built and running; the build machine's own base comes first,
built by the one that runs), writes the plan to the store, asks the first tier and returns. Every
outcome advances the plan; a ticker advances what outcomes cannot; a controller replaced mid-plan
resumes it. status lists open plans and names one that has waited too long.
A provider is a (node, module) pair (design 23), and the pin — the one way a
consumer names its provider — named only the node. Two modules on one node
can both answer a provision (public-acme and step-ca both offer acme-ca on
novox), and then the resolver, given a pin naming that node, took the last
provider listed: a coin flip. The same ambiguity beside the consumer was
settled by a map walk — random per plan — which is how novox's own
route-proxy got its issuer (novox/hq #258).
- `pin <node> <provision> <from-node> <module>`: both halves, always. The
console gains `pin` and `unpin`. The provider may be on the consumer's own
node, since two modules beside it can both answer.
- The resolver refuses ambiguity instead of picking, across machines and
beside the consumer alike, naming every candidate as node/module and the
form of the pin that settles it. A plain capability that grants nothing
and serves nothing (three shells beside an editor) is not a choice to put
to anybody and stays as it was.
- provision_pin gains a nullable module (0050); records made before are
completed where the node they name answers once, and left for a person
where it answers twice (0051).
- The provider of something already satisfied is looked for among what was
assigned, not only what the walk has reached — a consumer reached before
the provider beside it no longer loses its binding.
- The start-time check that every declared verb is runnable samples each
verb's required arguments from its schema instead of three guessed keys.
Live consequence: a node that has two providers of one bound provision
assigned (novox: acme-ca) resolves only once pinned —
`pin novox acme-ca novox public-acme`.
The controller knew which modules were built against which base artifacts and used it only when asked
(build --on). A merge that rebuilt the runtime image left forty-two modules on the old image until
somebody asked, twice, by hand (hq issue 186). The merge now takes every module standing on what moved,
through every layer, into the same rebuild, in base order — the same rebuild the flag does, asked by
the merge that made it necessary.
sendTo — the path a roll-out, a rotation and a secret change take — issued memberships after its
sends (ADR 0160); the push command, which sends the same declarations through its own loop, did
not, so the one command operators run issued none. Said once in the same words after the sends.
A stream publish waits for its acknowledgement as long as its context lives, and the server never
acknowledges a publish it refuses. Issuing memberships after a push used the daemon's own context, so
the one refused membership of 2026-10-01 (hq issue 183) held the controller's receive loop for good:
no report, no build outcome, no merge was heard until a restart (hq issue 185). Issuing one
membership is now bounded to ten seconds, and a push says how many could not be issued and stands —
the machines keep the shape they derive until the next push.
The store's databases is not postgres's postgres_list_databases, and a holder may serve both. A
claim's serves names the seat's verbs the module implements for the role; absent, the module's own
tools must list every verb the seat promises, which is how a module named like its seat says they
are one and the same. Registration refuses a claim naming a verb the seat never promised, and the
credential's claims carry the claim's own verbs to the runtime.
For every module on every machine the controller composes what that instance serves — its machine's
address always, the module's plain address in a queue when it is alone or its definition says its
instances are interchangeable — the verbs of the seats it holds at the seats' subjects, where its
events land, and what it may reach, resolved the same way for the modules it invokes. Published
beside the node's declaration on `mesh.assignment.<node>.<module>`, last per subject in a stream
that allows direct reads, and the account may read exactly its own. Composed from the same records
the bus's accounts are, so what a runtime serves and what its account may are one composition.
`instances: interchangeable` is the one fact a definition states for it.
The shape issued is the shape the mesh already had, so nothing moves when the membership arrives;
the runtime that reads it instead of deriving it is the next piece.
`invokes: [<module>.<tool>]` now grants `mesh.mod.<module>.tool.<tool>` and the same with the
machine as its last token, which is how a call reaches one machine's instance. The broker
credential the mesh writes carries `claims`: each seat the module claims, its scope, and the verbs
the seat promises, so the runtime serves them on the seat's subjects; the holder's grant, composed
from the holding, is what admits the subscription.
