The controller cannot know the operator's account's uid, names an access by its
declared id (which holds a slash), and should not parse words. A tool runner's
account may now come by name alone and is read here (refused when absent or root's,
its uid said in the access's listing); the take act matches the declared id exactly;
an access wait says its reason (keep or disk) and, for a filesystem that refuses
ACLs, whether the take act can enable them.

The build seat runs merge-check as root, so every folder a test made was root's
data, which is never kept (§12), and 28 tests failed for that alone. A test's
folders now stand for an operator's: run as root, they are given to nobody before
they are judged. The root rule is unchanged.

The engine delivers before the controller half, and today's controller sends no
identities, users or taken. Keeping now starts only for an access whose folder has
users, or a declaration with identities; every other access is mounted when present
and refused when absent as on main, with nothing made, kept, held or judged. A
leftover whose walk could not run says why, not always that its disk is away.
A name read that timed out gave an empty name, which differed from the recorded one
and so reset the record: a folder kept while empty asked again, a warranted one was
walked again. An unnamed filesystem now leaves the folder exactly as it is, the
access is said not known for that look, and it resumes once it is named.
A container was still created over an unmounted mount point, so its writes landed on
the filesystem below; a folder moved to another disk was kept on the old warrant; and
entries left by a drop or a move that could not run lived only in a log line. Every
container mounting an access whose disk is away now waits, the warrant holds only for
the filesystem it was carried out on (the wait names the new one, path-free), entries
left on a filesystem are recorded per mount and taken out when it is back, and every
leftover is said as unhealthy until it is. A hung stat is shared per path, and a
widened mask takes from other entries only the bits it adds.
A walk run while a dataset was unmounted wrote onto root's empty mount point, or
"dropped" entries from it and forgot the ones on the data; a folder kept while empty
below an unnamed mount was then swept whole once the disk mounted, with no warrant.
Every walk is now judged as an apply is, a changed mount judges the folder afresh, and
systemd .mount units and mounts seen are read for the first-sight rule. Widening a
mask caps the entries it limited, so the owning group gains nothing. The watch lets
go of removed folders, re-arms on lost notice, reads users under its lock and ends
with its context. A drop that cannot read an ACL is counted, a broken folder's words
carry no path, a grant's group that could not be left is tried again, and a folder's
stat is bounded.
A module's containers ran as whatever their image chose and shared folders were
made writable by putting accounts in the folder's group (ADR 0312), which ADR 0325
supersedes. The engine now makes each declared module identity as a system account
with the controller's numbers, runs a container declaring `identity` as it, and keeps
each placed shared folder usable through one POSIX ACL entry per user, set through
the kernel's xattrs on descriptors it opened itself. A folder holding data is kept
only after the operator's warrant (the take act); a missing folder is made where its
data lives and waits where its disk is not; root's data is never kept. A watch and a
bounded sweep put back what an app narrows. The group grant is removed, and what it
put an account in is taken back.
Reuses the descriptor walks, the create act, the missing-path wait and the warrant-
backed act message from the paused issue 567 branch.

Once a mesh directory's mode and owner go only through a walk that follows no
link another account could make, a directory behind such a link is refused
and its module gated: on the control-node that could stop the controller.
The operator is to be told which directories that walk would refuse on every
node before it lands. So the engine judges the declaration it keeps with the
same walk, making and changing nothing: on a signed ask from the controller
(mesh.node.<node>.ask.judge-directories, held to the hand-over's checks) and
as `nox-mesh-host judge-directories` at the machine.

The engine is built without cgo, so a check by name missed a root group a name
service holds or one number carrying another name: the root groups are resolved
to numbers (now with kmem and shadow) and a number named nothing is refused for
containers too. A group without write is granted nothing (§2). The look reads
each path off the lock within five seconds, so a dead network mount cannot stop
every health statement. A grant's account may not start with a dash. A group a
record leaves for another asker is handed to it, so it is still taken back when
the last asker goes (§5). The scheduler skips paths issue 339's guard refuses.
The engine reads the group owning the accessed path at apply and gives it to the
containers and the tools' account an access's new `grant` names: --group-add for a
container (recreated with it), an account group for the account (recorded, taken
back as ADR 0252 takes back). The path is never changed; an access whose group
cannot write is stated unhealthy for the operator to decide; group 0 and the
root-granting groups are refused by name. The tool runner restarts through the
restart-on the controller gives it, because the access reports updated exactly
when the account's groups moved. Health says GrantContract (4), which tells the
controller it may send `grant`.

A newer sequence carrying an older view of the assignments undeclared four
assigned modules on 2026-10-04; the sequence cannot tell it, the generation
can. The engine keeps the highest generation it applied, refuses an older one
before reading the machine unless the declaration is a gate's put-back, and
says the refusal in its report so the controller can name the sender. A
declaration without a generation is applied as before, and every report says
it reads one, so the controller sends it only to engines that do.

A module whose only fault was a secret the operator had not given yet was
stated unhealthy, failed its first-node gate and was put back. The engine
now reads the tool's answer through mesh-sdk go/health and states such a
resource waiting, with what it waits for, on one look; a malformed wait
stays unhealthy.

The walk kept its progress every minute and nobody could read it: root-free said only that a search ran.
The account verdict now carries the progress (counts, times, mount points; never a path) as fields and in
its reason, outside what makes a verdict changed. A signed ask from the controller's terminal throws the last
search away and starts a full one, after the operator removed by hand what it found.

The control-node's walk takes far longer than the engine runs between
updates, so a search that starts over at every restart never completes.
The walk is the engine's own, in lexical order, so its progress is one
cursor per filesystem, kept every minute beside the engine's state and
carried on after a restart while younger than rootsearch.FreshFor. It runs
on a thread of its own at nice 19 and the idle I/O class.
A machine with millions of files never finished the walk within fifteen
minutes, so its agent account was never judged and the router refused to
link. Only root can make a setuid-root file, so a complete search stays
sound until root acts: it now runs at idle priority with no bound, is kept
beside the engine's state, judges for rootsearch.FreshFor from its start,
runs again daily and after an apply that moves accounts, packages, actions
or sudo rules, and an incomplete or stale search is never free.

Two holes the review proved. The ask's subject proved nothing — a responder can reach it through a reply — so the engine now verifies the mesh's signature over a fixed context with the key it verifies declarations with, before reading anything, and refuses an ask for another node, expired, good too long, without a nonce, or replayed. And the apply followed a link the hand-over had refused: a component swapped for a link after the record carried root's chmod and chown to its target. A handed-over directory must now still resolve to itself, and is changed only through one descriptor opened from / with no link followed (fchmod, fchown). Tests for the reply guard, the run loop's hook, the fallback renewal on proof and a non-regular fallback; 27 checks each removed in turn, each failing a test.

The file on PATH was the engine a person copied at installation, and every delivered engine ran from the versions directory: the operator typed hand-over and a build from before it answered "unexpected argument". A proved engine now copies itself over that file when the bytes differ (never a link). And the hand-over of a directory used as found (issue 339) gets its channel: the controller's terminal asks this node's engine on mesh.node.<node>.ask.hand-over; the engine judges every value — the ask's size and shape, who asked, the path as it states it, a directory and no link, through no link — and records it or refuses and records nothing. Every text the engine addresses to the operator names the nox line (ADR 0272); the engine's own subcommands are install-time and rescue, and its usage says so.

- A request that timed out was said as "the controller was not reached,
nothing ran", though the line may have run. The engine now follows a line
the controller answers as running, by its call, until it ends; when no
answer comes in time it says the line may have run and names the call.
"Nothing ran" is said only of a request no controller took.
- One account could hold the socket: accepting waited for a free slot, and
a connection could stall before its deadline was set. The deadline is set
at accept, before any lookup; each user id has two lines at once and the
machine eight, and one over is answered busy at once.
- A container running with the operator's user id shares the number, not
the machine: a peer whose mount or user namespace is not the engine's is
refused, and nothing is asked.

The records send the operator to "the controller's terminal", and nothing
reaches it (hq issue 343). mesh-cli holds no credential: it asks the engine
on its own machine over a socket. The engine reads the asking account from
the kernel (SO_PEERCRED), never from the program, and asks the controller on
mesh.control.<node>.cli, its own node's subject, so the bus server says which
node asked. The controller decides what the line may do; nothing received
on the socket is run or applied here, and the socket has no network address
(ADR 0004 stands).
The local protocol is the SDK's go/cli package, at a pseudo-version of its
branch until that merges and is tagged go/v0.1.8.
An account could replace ~/.claude with a link to /etc and have the
node-engine chown, chmod or write through it on the next apply. Below a
person's or an agent's home every component is now opened without
following a link, and a link refuses the resource in words.
The root judge also reads doas and polkit rules, the container runtimes'
sockets with their ACLs, ACLs on the secrets, and setuid-root programs no
package owns, in the C locale; Judged and NotJudged write down exactly
what it covers (hq ADR 0266 review).
An account an agent runs as (novox/hq ADR 0266) is read on every look for a
uid of 0, a group that grants root, any sudo rule and a mesh secret it can
read; any way found is unhealthy and said, a read that fails is unknown.

The third review of #64 (hq issue 339): an ExecStart continued over lines, a
quoted path, a variable from Environment= or EnvironmentFile= across the unit
and its drop-ins, dockerd's --config-file and podman's TOML literal strings
each hid a data root from the guard. The running runtimes are now asked first
(docker info, podman info) on a runner of the guard's own, and the files are
read beside them in all those forms.

The review of #64 asked for containerd's tree, dockerd's --data-root from its
unit and drop-ins, and podman's graphroot to be refused like docker's own
(hq issue 339); and the controller now tells a directory a send found from
one found before it, which needs the time it was first found kept across
applies instead of the time of the last apply. A hand-over now names the
resource it was for, so it lapses if another declaration points at the path.

A directory the engine used as found kept its owner and mode in silence, so
a module that cannot write it would just fail (hq issue 339 review). Each
one is now a WARNING in every apply's log and its module's resource of kind
directory, stated unhealthy on every look with its owner and what was
declared, which the controller raises as the module's condition; `mesh-host
hand-over <dir>` at the machine hands it to the mesh, and the next apply
gives it the declared owner and mode. The guard also refuses the spool, /opt,
the container runtimes' data (its configured data-root too), and an account's
.ssh as an access, a mount, or a directory anywhere but its own home.

A module puts the operator's account in a group by declaring the account with that group alone.
The node-engine now records each group it added, takes back only those when nothing declared still
asks for them, refuses a group the machine lacks before usermod runs, and states each such account
as its module's resource of kind account: relogin needed while the running session lacks the group.

Liveness judged only what a module runs long-lived, so a module whose
daemon is a package's unit started by D-Bus activation failed at every
start while its machine read healthy, and a degraded service manager was
said by nothing but the profile.
The engine now reads the failed units of the machine's manager and of
every account manager the declaration names, on the two-look rule, and
says whose each is: a declared service or process, a unit file the mesh
writes, or a package the mesh installs makes it that module's, said as
an unhealthy resource of kind unit; anything else is the machine's own,
said in the statement's new units field. It reads; it never acts.
Issuing the token sends the hub its new peer, and the hub applies it on
its own time; a bus dialled before then timed out naming the bus. The
first tunnel now waits for a handshake with the hub, and says so in the
tunnel's words when there is none (novox/hq ADR 0169).
nox-mesh-host key makes the tunnel key, or reads the one made, and
prints its public half for the token to be issued for. enrol with a
token that carries a tunnel takes that key, refuses another, writes
mesh0 with the hub as its one peer and starts it, then reaches the bus
over it (novox/hq ADR 0169). Tokens without a tunnel enrol as before.
A VPN client rewrote the laptop's resolver file and every mesh name failed
while each module read healthy: nothing asked the machine. The engine now
looks every 30 s at the resolver file the uplink holder declared (naming
the program that rewrote it), the names through each listed resolver
(NXDOMAIN for a mesh name's IPv6 address is a finding, issue 262), the
tunnel's handshake with the hub, the bus and the default route; a part is
unhealthy on its second failing look, and the statement carries it.
Liveness alone could not see a web application whose port was open and whose
program ran while every request hung for eleven hours (issue 145). A resource
now carries the `health` its module declared: the engine makes http and tcp
looks itself from the machine to the endpoint's published port, reads a unit's
readiness from the show it already makes, hands an exec command or the image's
own check to the runtime as the container's check with the declared timing and
reads its state from the inspect it already makes, and asks a module's tool on
its own node tools. Starting until the check passed, unhealthy once its looks
after the grace fail the declared number of times; never more looks than the
measured budget; nothing restarted. The statement says contract 2, which tells
the controller this engine may be sent the field.
mesh/merge-gate pass: builds mesh-host → ace, g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
A container that crash-looped after its compose applied passed every check the
gate had: nothing looked at what a module runs. The node-engine now judges every
long-running resource on every look — one read of the runtime, one per service
manager — keeps the restarts it counts across recreates and its own restarts,
and says the state in every report and as an event on change, again every minute
while not healthy. It reads only; nothing is restarted for being unhealthy.
The launcher trusted a counter only a by-hand reconcile ever cleared and a
known-good nothing in the daemon wrote, so no machine could roll its host back;
the controller and the node tools were replaced in place with nothing kept.
- The launcher runs a delivered host that is not known-good on trial: one that
crashes, stops for nothing, or does not report within ten minutes goes back
to known-good, once per version, recorded in rolled-back. The host proves
itself when the mesh takes a report under its own build, says every standing
verdict on its reports, never stands aside for a rolled-back version, and
restarts its service once when its launcher was replaced on disk.
- The engine keeps the controller's and the node tools' previous build beside
the new one and judges the new one: the lease taken by the controller it
started (read-only direct get of mesh-controller_lease/holder), or this
machine's runtime answering $SRV.PING.node-tools.<node>, within sixty seconds
of time it could ask. Not healthy: the previous restored, once, said. Proved:
the previous deleted. A build declared not-reversible is never rolled back.
- Retire never removes a version newer than the running one.
A delivery and the five-minute reconcile were two paths that applied, ordered only by a lock, and
each order it allowed was met live (issues 257, 261, 267). Now both only enqueue: one worker takes
the newest declaration held when it starts, applies it once and makes one report, and reports leave
in the order they are made.
A declaration may carry the controller's lease epoch beside its sequence; one older than what this
node applied is refused before anything is touched, counted, logged and reported. A report carries
the declaration's epoch and sequence and the host's own report sequence, kept on disk so it goes on
increasing across restarts and self-updates. Without an epoch, today's behaviour stands.
A host that delivered its own successor stood aside before the report of
that apply was published, so it failed with 'context canceled' and the
release plan waited for a report that never came (novox/hq issue 264).
Reports are now published on a context the stand-aside does not cancel,
and the last apply's report is kept until the broker takes it and said
again on the next link, so a crash between apply and report is covered too.
The five-minute reconcile read the kept declaration and then waited for the link's apply; the
link keeps a declaration only once its apply ends, so the reconcile applied the older one over
it. A module assigned a moment earlier was given back, and the report named a declaration the
mesh no longer recorded as sent, which held a plan at its first machine.
A while-stopped step stops its module's containers, and an apply arriving
mid-window read the stopped server as broken and recreated it running under
the step - for the store's collector, a registry taking an upload the sweep
then deletes. The scheduler now records each window under the node's state
directory before its first stop and erases it after its last start, so every
apply on the machine (daemon, reconcile by hand, installer) reports a held
container held-still and leaves it for the first apply after the window.
A window whose host died, or past six hours, holds nothing; the report says
which windows are open.
An account's manager runs only while it is logged in or lingers. A user-scoped unit
whose manager is not running is now "waiting" rather than failed, its record kept as
it was; its removal is never fatal (kept recorded, retried) and an account that is
gone is forgotten. Whether the manager runs is asked of user@<uid>.service in the
machine's manager: asking the account's own, through --machine, logs it in.
The user shape gains `linger`, set with loginctl, read back from logind's record,
and given back on removal like the shell. Unit files the mesh writes under
~/.config/systemd/user or /etc/systemd/user make that unit the mesh's, and made,
holds and found units are keyed by manager and name, so an account's unit and the
machine's of one name are two units. A service moved between managers gives the old
one back through the manager it was in. OpenRC refuses both.
Every table and chain that refuses traffic is reported with whose it is:
the mesh's, the found firewall's, the container runtime's own, a ban, or
other — the runtime's user chain is other, which is where both predecessors
kept their rules, in the legacy filter on one machine and invisible to the
mesh. Adoption's threshold does not move; a converged machine's report
grows by its filters and its found firewall's state.
Convergence is a state the host keeps: a found firewall enabled again is
retired again and said; a reconcile that finds it inactive records that it
was found so, never that the mesh did it; a step skipped after a failed
apply is said. A retirement the mesh began and did not finish is finished.
Fixtures are rulesets captured from three machines of the first mesh.
The filter accepts what does not arrive on a link the machine names as
outward, and the host named only links carrying a default route. An
unplugged wired port was left unfiltered for whenever it was plugged in
(novox/hq issue 197). A link backed by a physical device is now named
whether or not it is up.
Every held thing carries what a take compares: for a found container its image and the image's date,
the networks it is on and the other containers on each, its mounts and published ports, beside the
declared image (and its date once pulled), ports and volumes, with the downgrade decided when both
dates are known; for a found file whether the declared content differs and how, as lines lost and
lines new. A resource whose target moved keeps the former target on record as an orphan, so the next
apply removes the container or file the host wrote under the old name (issue 097). Every apply reports
the strays: containers the mesh neither wrote nor holds.
One capability per manager — uplink-networkmanager, uplink-systemd-networkd, uplink-dhcpcd — from
systemctl is-active, so the uplink seat's holder for a manager this machine does not run is refused
the way any missing capability is, naming it (issue 138). The apply that reports detects the profile
again and sends it, the same shape enrolment sends, so a machine that switched managers reaches the
mesh at its next push.
novox/hq 04-ISSUES/107. A declaration's only identity was the digest of
its bytes: a host could say "not the last" and could not say "older". On
the link, nothing refused an older one at all, and the drain picked the
last to arrive — wrong exactly when it mattered, a backlog drained out of
order or a broker that split a burst.
A declaration may now carry a sequence, one higher per send. A host
refuses one lower than what it kept, whole, and says why. The drain keeps
the highest sequence in a batch rather than the last to arrive.
Only when both sides claim an order. Absent reads as zero — "no ordering
claimed", not "first" — so a controller that sends none is still
understood and a host that kept one before it understood them compares
nothing. That is what lets hosts go first and the controller follow, which
is the order 087 says a new field needs.
novox/hq 04-ISSUES/163. The host asks after every apply whether a newer
host is delivered than the one running, and asked with the link-time
version stamp — which every delivered host carries as "development
build", because the version comes from where the binary sits now (0142).
So a delivered host never matched the newest delivered version, stood
aside on every push for ever, and because standing aside cancels the
report, the mesh never heard from it again.
Measured on two machines: each push produced "host <v> is delivered;
standing aside" for the version already running, then "applied, and could
not tell the mesh: reporting: context canceled". A machine restarting its
host on every push and reporting nothing, reading as healthy.
Asked with the running version now. Half of 0142 was applied to the
report and the known-good record and not here; this is the other half.
novox/hq ADR 0142, which decided this and was not implemented: "It is
unpacked into a directory named for its version, so it can read its own
version from its path. The stamp goes, and with it the need for a build to
know what it will be called."
The mesh's toolchain stamps no version, on purpose, so a delivered host
called itself "development build" and the mesh could not tell which host
any machine ran — which is the whole of what 087 added. A delivered host
lives at <libexec>/versions/<version>/<binary>, and that directory is the
answer.
A host placed by hand keeps its stamp, which is the honest answer for one
the mesh did not deliver, and is every machine until a delivery reaches
it. A binary sitting anywhere else is not read as a version at all.
The decision is split from the reading so a test can ask about a path
without being that binary.
