A head checked again through mesh-delivery reached the direct verdict with no
base head, so a head no build judges was answered with no trunk commit and the
merge tool would refuse it (novox/hq ADR 0323).

A change touching no module, in a repository with no merge-check.sh, was
answered by the controller with no trunk commit, so the merge tool refused it,
asked again and refused it for ever (novox/mesh-tools-go; novox/hq ADR 0323).

A check judged the head alone, so two pull requests that each passed could
break the trunk together (node-engine #66 on 2026-10-09), and a recheck after
the trunk moved judged the same head again. The build seat now merges the head
into the trunk's head in its own clone, never pushed, fails a head that does not
merge cleanly naming the files, and the verdict names the head, the trunk
commit and the commits read beside it, for the forge and mesh-delivery to weigh
against the trunk's next move (novox/hq ADR 0323, issue 341).

Since #256 delivered, the node-engine judges every read-write access by the path's group alone and
states six media modules unhealthy on ace, though they write their folders as the owner; every
delivery there fails its gate (hq issue 567). ADR 0325 replaces ADR 0312; until it is built, the
controller sends no grant, as before #256.
This reverts commit 3cfc121670.
The send minted a random value for a plain own secret marked issued-by outside and placed it, so a
module could not tell "not given" from "given and wrong" (ADR 0228). It now places only a value a
person gave: not given is no file, an empty value where a module's file names it, and nothing to
restart on, as ADR 0283 decided for a family's member. A value the mesh made for one earlier is not
read as given.

A resource on the resolver file was left out by the check and still composed by the declaration, so an
uplink declaring it as a resource beside the resolver passed with two writers; it is refused again, as
before. And /etc//hosts or /etc/../etc/hosts is /etc/hosts to the machine, so it is compared cleaned.
A seat names no root or top-level directory.

PlanByID pasted its id into the query, and the id comes from a caller of
the plans verb: an id holding a quote changed the query (x' or '1'='1
answered another plan). The id is now $1, and RecentPlans's limit too, so
no plan query is built from a value.

Which module owns /etc/hosts or /etc/resolv.conf on a machine was answered only by reading every
manifest, and a module not holding node-hostname could declare /etc/hosts where nobody held it.
hq ADR 0287 makes the paths part of the seat's definition: node-hostname names /etc/hosts and
/etc/hostname, node-uplink names /etc/resolv.conf stepping back for node-resolver, node-resolver
names /etc/resolv.conf.
CanHold refuses a holder that does not declare every path (registration and handover), registration
refuses a module declaring a seat's path while claiming none of the seats naming it, a module's own
seat names paths under the same rules (node only, literal, not named by another seat), composition
refuses a generated resource on a seat's path, the uplink's step-back is read from the seat instead
of a special case, and `seats` shows each seat's paths and who owns each on each machine.

An agent following a rollout had plans answer once, in prose, and polled the
console with a curl loop of its own to be told a plan moved. plans now takes
wait (a plan's id), until (moved, tier or done) and bound, and answers when the
plan moves or the bound passes, saying which, with the plan as data and its
line as the output.
A call's one answer has to reach the console inside its thirty seconds, so
link.AnswersWithin lets a handler that waits on purpose hold its answer up to
LongestAnswer (25s) instead of AnswerWithin; the bound is at most 20s, and a
caller following a plan further asks again.
The xz reader keeps one delta or BCJ decoder for every block of a stream and frees them only when the
stream ends, so a file of many tiny blocks grows the heap with its length: about 67 MiB live for a 6 MB
`xz --block-size=1 --delta` file, about 5.6 GiB at the 512 MiB download cap.
The file's framing is now walked first, without decompressing: stream header, each block header, the
LZMA2 chunk headers (each carries its compressed size, so a chunk is skipped unread), padding, check,
index and footer. A file of more than 1,024 blocks or 16 streams is refused, as is an index whose block
count is not the count walked. The index alone is not trusted because the reader compares it with the
blocks only after decoding them all, so a lying index would still be decoded. Refusing delta and BCJ
outright was not chosen: it needs the same walk to see each block header, and would refuse sound
releases filtered with BCJ.
1,024 blocks keep at most about 0.35 MiB of decoders. Betterbird's archive is 1 stream with 1 block;
multi-threaded xz cuts blocks of 3 times the dictionary, so 512 MiB in blocks of 512 KiB still fits.
The library stays unforked.

The issue tracker holds a fix to the budget of the slowest-budgeted module it
moves, and gives none to a fix that moves no module (hq ADR 0313 §2). The
walk's class covers every merge a walk carries; the plan's class is the
change's own: core, leaf, or none.

ulikunitz/xz's ReaderConfig.DictCap is a minimum: a stream asking for a
1 GiB or 4 GiB dictionary was given it. github.com/therootcompany/xz, a port
of xz-embedded, takes a maximum and refuses a block whose LZMA2 dictionary is
larger before allocating it. 64 MiB, xz's largest preset.

Root chowns a directory to the number its owner's setting names, so a key
an owner asks for must not change through the settings verb: any caller
could have set puid to 0 or to its own uid. TerminalKeys now takes every
${setting:…} in a directory's owner, whatever else asks for it, and the
owner is written as the parsed number so "0001" never reaches the
node-engine as text (review 60).
A media manager runs as the puid/pgid its assignment sets per node, but a
declared directory's owner was literal, so a folder the app must write was
refused on a machine whose identity was not the image's default. A
directory's owner now takes ${setting:<key>} (user, or user:group), filled
at composition and refused unless the value is a whole number, and the
module check refuses any other shape or a key the module asks for nowhere
else.

Betterbird's pinned .tar.xz failed on the build seat with "this build seat has
no xz to read it": the seat's image is the catalogue's build-agent recipe,
which installs git and docker-cli alone, and xz had been added only to
cmd/mesh-builder/Dockerfile, which the seat does not build from. The stream
is now read with github.com/ulikunitz/xz (vendored), its dictionary capped
at xz's own largest preset, and what it unpacks to bounded as before; the
xz line in the unused Dockerfile is taken back out.

The real mesh-vault manifest declares its directories without a path, so the
list left its state and ledger out, and a place still holding a placeholder
vanished from it without a word. The provider's directories are now resolved
where the node places them, an unresolved place fails the composition naming
the module, and a node-reads holder whose account is put in a group is refused.

The queue verb answered only a table, so nothing outside the controller
could say an ask's place in the queue. It now asks its command for JSON:
each ask's state, kind, repository, commit, machine, since and position
among the waiting, with the table carried beside it and answered as the
verb's output, both written from one read. A repository's password, if
one were ever written into it, is left out of what is shown.

Before the node-engine gives a mesh directory its mode and owner only through
a walk that follows no link another account could make, the operator is to
see which directories that walk would refuse on every node, the control-node
included, where no tool reads a path. `node judge-directories <node>` signs
the ask as a hand-over is, under its own context, and prints the engine's
one line per directory; it changes nothing, so it is a seat verb an agent may
call. The node is granted the subject, the controller alone its publish.

Reading a file, searching one, listing a directory, the owner and mode of each
component of a path and looking up an account had no mesh tool, so they went
through the login shell's execute as the operator's account. node-reads is a
node seat with six verbs, each saying the commands it replaces. Its holder must
run as an account of its own (ADR 0310 §3), and its own runtime is given
MESH_SECRET_PLACES: the directory of every module's own secret, every credential
file and grant directory, the vault's directories and the sealed-secret keep,
so it refuses them by name before any read (§5).

The url was skipped by the installation check, so an installation's host or
an address passed; it is judged whole now, the vendor's host declared in the
artifact's names-on-purpose, and an address or a reserved name as the host
is refused. Only the version's dotted-quad reading is skipped. The unpack
caps its entries, drains xz before waiting for it, reads a pax global
header and a nested within's parents, and a redirect off https is not
followed.
A mail client's release is about 80 MB per version, too large to keep in a
repository at every upgrade, and an add-on whose licence forbids copying it
to third parties may not be in a repository at all. An archive artifact may
now name url, sha256 and version (and file or within) instead of from: the
build seat fetches it once, refuses it when its digest is not the pin's and
names both, keeps it in its workspace under the digest (a vendor that serves
only its newest version cannot break a later build of the same pin), and
packs it like any archive, so a node gets the mesh's own archive by digest
and never asks the vendor. The build seat's image carries xz, which Go's
standard library does not read. The installation check takes the vendor's
address and version of such a pin for the world's, as a registry is an
image's.
A path beginning with the same letters is another path, and a read-only mount
of a read-write access is still granted: the grant follows what mounts it.
Each read-write access is composed with a grant: the module's containers that
mount its path and the account its tools run as (the operator's, or the module's
own under ADR 0259 §8); that runtime restarts on the access, so it holds a group
the engine put its account in. A read access grants nothing. Sent only to an
engine whose statement says GrantContract (4), since an older one refuses the
field. Pins the node-engine at the branch that reads it.

cancel, clear and rebuild kept a walk's end or restart without saying it, as plans stop, retry and
release-backlog did before them. The controller's run now says every save a verb makes on the bus, so the
next verb cannot lose a mark the same way. A stop is cleared when a walk is resumed, so one that fails again
ends failed and the search for its merge runs (review 21, ADR 0308, issue 532).
plans stop|close, plans retry and upgrade release-backlog kept a walk's start or end mark without saying it,
so the router would hold what the walk touched until its bound; each now runs on the bus as plans go does.
A hand stop keeps who stopped it, so its outcome is stopped, not failed (review 15, ADR 0308, issue 532).
The router holds what an open walk touches and tells its result once; it can do so
only if plan-moved names the walk's start and end, the modules and machines it moves,
what a moved tool runner or node-engine carries there, and how long to hold.

A merge from any head waited for the window because the controller could not
see a group's members, so the window skip changed nothing in production and
unrelated merges walked one after another. The controller now asks
mesh-delivery's groups, within 3 s and before the plans are held: a merge
waits only when its head's group has another member whose pull request is
open and whose merge it does not keep yet (ADR 0306 §2). No answer means it
waits, and its batch says why. A headed merge in no waiting group and related
to no batch is cut at once, as one from no head is (ADR 0304 §1, ADR 0306 §3).
The controller's grant names mesh-delivery.groups. The installer's first user
list in mesh-host must carry it too before the genesis test can pass.
A merge waited the whole window even when nothing assembling shared anything
with it. It now joins only a batch it is related to (ADR 0304 §1, read by ADR
0306 §3: repository, a module the cut would move, a graph edge, a group head),
folding the newer into the oldest when it relates to two. A merge related to
none starts a batch whose window is closed at once (PlanBatch.CutAtOnce),
unless its delivery group may still have a member to merge (ADR 0306 §2).
The controller cannot see a group's unmerged members (that is mesh-delivery's
record), so a merge from any head still waits, in a batch of its own: the safe
error is to wait. Walks stay one at a time; a batch cut at once queues behind
an open walk. A stop's merges walked again join a related batch, or their own.

Every look rewrote the condition's value in the conditions bucket, because the
value carried the count of looks, the last look and the newest evidence: 131 647
writes in four days for twelve open conditions, against ADR 0289's rule that a
bucket is written only when what it describes changed. The looks now live in the
controller's store (migration 0095, condition_looks), the bucket holds what a
condition says and is written only when that changes, and the conditions verb and
the condition events put the looks back.

A registration asked the forge while node-tools re-served after a tool-runner
rollout, heard "nothing serves gitea.gitea_api", and failed a good build's
plan. The bus's not-served answer is now link.ErrNothingServes (and a timeout
link.ErrNoAnswer), and the registration asks again for up to 90 s on those
alone, never on a refusal; past the bound it fails saying how long it waited.
