A merged change's walk waited minutes on its build behind checks in a
first-come queue. The queue now hands deliveries out first, a check that
has waited ten minutes before deliveries asked after it, and says each
ask's kind; the order is kept in the work queue itself.

gatedSend took its judged moves from the record, so on a machine kept at
a newer controller the gate judged the controller moving back to the
record, read its own send's kept controller as a later build there, and
was superseded with nothing judged. The kept moves are now left out
there as in ungatedIn (withoutKept). The doc says the bus step keeps
too, and the three store tests are listed.
Refusing the whole send wedged a machine whose gate put back the
controller and whose put-back send was refused: every later automatic
send there was refused, retried each tick, and held up every other walk.
A send now composes the controller and the node-engine at the build the
machine was last sent when the mesh's record is older, and carries the
rest; nothing is refused or retried, and a plan whose own build is the
older one ends with its gate superseded. A sent build that failed its
gate is never kept, so the next send completes a put-back. The condition
names the two ways out and clears on any send that carries the record,
a person's push included.
The fix's own test reads GivenOwnSecret, which the commit before does not have, so it cannot be laid over it. TestReplay401 asserts the same outcome with register, assign, planFor, declarationFor and the inventory's secret reads; it fails on 1e28342^1 and passes on main. Named in testdata/store-tests so a skip without the store fails the check. Replay for hq issue 401.
On 2026-10-02 a plan sent the control node a controller older than the one
running there, whose seat row the newer build had widened; the older binary
refused the row and the mesh went quiet for ten minutes. ADR 0185 took the
outage out of it, and the race stayed open.
Every send but a person's push now refuses a move of mesh-controller or
mesh-host to a build asked before the one its machine was last sent (the
builds' registration order, issue 219), whatever composed it — gated or not.
A gate's own put-back is the one exception, for the modules it puts back,
and says so in its send's scope. The refusal is the send's error, which the
plan keeps as its note, and a warning condition on the machine, cleared by
the next send there that carries no such move.

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.

Every argument of plans that names a plan (id, wait, stop, close, retry,
go) is checked once where the call becomes a command line, against the
ids the mesh gives plans (plan-<digits>, release-<digits>), so a quote
from a caller never reaches a command or the store (review 75 on #266).

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.

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.

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).

assign read the whole mesh before its write, to record the seats held by
derivation, and that read printed on standard error that the node did not
resolve for lack of the seat the act was about to give it. The seat verb
answers with both streams, so the stale line came last and named the
assignment just made as its remedy.
The reads inside an act no longer print 'left out' lines; the node's
unmet seat dependencies and whether it resolves come from one planFor
taken after the write, and every other machine from blockedElsewhere.
unassign now says when its node does not resolve, from the same
resolution.
