The second sandbox fault of the same kind on mesh-host #200 (postgres's secret
reader handed, the module not): the engine stripped the whole catalogue from
the input it answers, so the sandbox composed the node's own modules from the
indexer's source manifests while the bus reader composes them taken in from
their builds (artifacts, templates archive texts, what is handed). Both sides
now go through composer.SentInput: the node's own taken-in manifests and kept
builds stay in the input, and the sandbox composes them over the cases'. An
input past what one bus answer carries is refused in words. A conformance row
composes one node through the bus reader and through the sandbox and requires
the same declaration.

A check that composes with a candidate's own composer (any mesh-host change)
gave it the indexer's manifests alone, and the input carries no catalogue, so
mesh-wireguard (shipped with mesh-sdk, no repository) was missing: "nothing
provides mesh-wireguard / mesh-addressing" on novox for mesh-host #200. Each case
now lays the provided module's manifest over its shelf, as the bus reader does.

An endpoint's subscription hands its asks over one at a time: two checks asking

Off the control-node an ask of compose-candidate ran into its 60 s bound: each of
its two compositions read every manifest in the mesh one key at a time over the
bus, on scratch copies of the shadow that kept nothing, so each ask read them all
twice again (about 35 s per composition on ace, g14 and shanks; 2 s on novox).
The answer at 60 s then came after the bus's one-minute reply window
(allow_responses ttl), so the bus refused it and the checker heard nothing.
Now the manifests are read eight at a time into the shadow before either
composition, a scratch copy keeps what never changes (manifest, archive, done
build) in the shadow too, the candidate is laid over a copy taken after the
composition without it, and the engine answers within 50 s: unready, naming what
it waits on, when not done. Every answer is said in one journal line with its
reads and its longest wait.

The checker asks by the composition key, <group>.<heads hash> (ADR 0593 §7), but the
indexer keys a candidate by its group alone (delivery.CandidatesKey). The node-engine
read the ask's key as the bucket key, so every check's composition was refused on
every node with "the indexer holds no candidate" (mesh-catalog #599, 2026-11-02).
It now parses the ask, reads CandidatesKey(group), and answers unready when the
group's candidate has moved to other heads. Both tests' fixtures had captured the
wrong key; they now key by group, with a slash in the group name.
Quick fix: this lookup. Thorough fix (a shared SDK reader that takes a composition
key and returns the candidate at those heads) not taken: one reader, one repository.

ADR 0593 §7: the composition is the node-engine's, so its tests hold
what the indexer's judge tests and route-proxy's tests proved by
composing: a bundle's words per machine, a Go bundle's delivery, the

vault refusals, the session's files, a field set aside composed whole,
route-proxy's manifest composing for a machine, a route endpoint's
machine port in six cases and the plan's route entry end to end. Two

ADR 0593 §7: the composer with its refusals leaves mesh-sdk, so mesh-sdk
carries no composition rule. The catalogue functions only the
node-engine's composition reaches (Resolve, Resolution's Compose,
Declaration, DataItems, LeftOut, Rules and the rest, the settings,
placeholder and template refusals, the rendering helpers) are copied
with their tests into internal/compose/resolution; a method of a
mesh-sdk shape becomes a function taking it first. The composition
calls its own copies, and the captured catalogue its tests read lives
here now, shared by mesh-compose's tests.

ADR 0593 §6: a composition read from composed-<node> is a record never
applied, and the engine applies only what it composes itself, so no
composition carries a signature and nothing is verified. The agent's
trusted signers, its signed-composition test and the unused signing
helper of the integration bed go, so mesh-sdk can drop SignComposed,
VerifyComposed and Composed.Signature.

The test budget: mesh-host is over 500 unit tests, so the three tests

ADR 0593 §6, §7, §9: the integration test runs the node agent against
the real bus under the grant the grants part composes for a node: it
publishes web's composition in composed-<node> with the digest its have
names, and answers compose-candidate for the indexer's candidate,
changing nothing. A node that cannot compose now answers unready, so
the checker counts it as no answer by the verdict and never by words.
The golden grant reads the indexer's candidates and verdicts as it
reads the builder's builds.
Claude-Session: https://claude.ai/code/session_01NcbgfJ9Gum47zkFKWRaovL
ADR 0593 §6: composed-<node> is written again, by the node's engine,
each composition with its plan. The verb composition finds a published
revision by the digest the have and want name, its resources', so a plan
on the record does not hide it. The golden node grant also reads the
indexer's verdicts, which compose-candidate takes for a candidate's
manifests.

ADR 0593 §7: a check's composition is the checker's, made from each
placed node's answer, since only a node can compose with its own sealed
values. The node composes the indexer's candidate in shadow on a copy of
its shadow's inputs, the candidate's modules laid over the indexer's
with their manifest verdicts, and answers per module composed (changed
or not), refused or held, and its own composition's verdict, within the
answer bound; it applies, writes and hands nothing. With input it also
answers the composition input, for the sandbox path.
Claude-Session: https://claude.ai/code/session_01NcbgfJ9Gum47zkFKWRaovL
ADR 0593 §6: the provisioner, the assigner and the view read compositions
instead of composing, so the node's engine writes each one it makes to
its composition state: the wanted builds, every placed module at its
newest done build (so the plan exists before the want moves), each with
its provisioning plan, and a module refused alone with its refusal. A
key is written only when it differs, and kept while among the module's
five newest or named by a want. A placed module's trunk build landing
now makes a pass.

ADR 0593 §1 and §7: compose, its bus reader and runtime reader, takein,
validate, the overlay generator, the composer's run and mesh-compose, and
the judgement of a move leave mesh-sdk for the node-engine's internal
packages, so no other module composes and a change to them rebuilds only
the node-engine. The shapes others read (the composer's request and
verdict, the overlay's names, compositions and answers) stay in mesh-sdk.
The node's grant is now a golden file of what the grants part composes,
since the composer of the bus's user list leaves mesh-sdk too.

The bus module on the bus node runs from what its agent holds (its own composition, or the declaration kept before the
switch: every novox have read 2026-11-02 names its own composition or none, and nats names a build alone), while
composed-<node> was written by the controller, which ended (issue 1126). The follower now looks at the agent's record
of what runs whenever it changed, writes again only when the file it names moved, and trusts no composition signer.

The controller ended by its unassignment, so a node that falls back to the
compositions in its bucket follows what nobody writes (issue 1126, A7). The
node agent now always runs its own composer: without a placement key it
composes nothing and keeps what runs, a placement it cannot watch stops the
agent and is said, and a candidate taking its placement away is refused
instead of answered as a return to the controller. The start-time placement
read, the end-when-placed watchers and the returning answer go, with their
tests and the three integration tests of the controller-composed path.

The controller ended by its unassignment and its lease is never handed, so
the engine's lease gate kept trusting the controller's key and the bus node
kept the controller's list as a fallback nobody writes (issue 1126, A6).
The engine now trusts no controller signature, its hand-over line names the
node seat's hand-over, and the user-list follower writes only the grants

A stand-in vault reloads a nats-server's users as the grants part's list is loaded, and the engine's own rotation code runs

switches only once the list holds both logins and confirms in the new login's name; at rotation-done the old login is
retired and its value dropped; with the list never loaded the test-dial is refused and the engine never switches; and an
abandon after the switch brings the engine back to the old login before the new value goes (ADR 0583 §2-§6). One integration

The engine dials as enrol.<node> on the pinned certificate, calls redeem with the public halves of its keys and a proof over
them (the SDK's RedeemProof, which binds the node and the keys and never the token's secret), asks again while the holder
says to, and verifies the vault's answer against the key its token carries before it keeps anything: an answer signed by
another key, naming another signer or node, or altered is refused and nothing is kept. A signed one is kept (membership,
login, keys), then the node dials as the login it was given, reads its key of node-logins, and calls confirm; nothing is
applied until its placement names a module. When the bus does not serve the seat to the token (the controller still holds its
lease) the controller's enrolment subject is used as before. The token's shape is mesh-sdk's now: identity keeps its names as
aliases. Tests: one added, paid by merging three identity token tests into one (net two fewer).

On node-logins' ready the engine fetches the new value through the vault's own hand-out (own/<node>/mesh-host/<login>, opened
with its sealing key), dials a second connection as the new login on the pinned certificate, and switches only if that
authenticates, then calls mesh-vault.node-account-confirm over the link as the new login (the vault is asked in the name of
the login the open link authenticated as, and only once that link is open). It keeps the old value until the key says the
rotation is done and drops it then, never before; an abandon, after the switch before or after the confirmation, switches
back before the new value is dropped; repeated refusals of the new login's credentials before rotation-done bring it back
to the old one, said as the finding node-account-fallback (in the journal: no route for an engine's finding to the watchman
is decided), and the same rotation is not tried again. Tests: two added, paid by merging two identity sealing tests into one;

A membership may name its Logins (ADR 0583 §1): the login in use and the password of each login held, kept beside the

and dials as the login it names when it holds its value, with the node's one inbox; with no key, or a key naming the first
login, it dials node.<n> with the membership's password as before. A change of the login in use drops the link so it is
opened again as the new one, and the vault is asked in the name of the login dialled (the subject names the caller).

their difference, and with write writes the key again from what was composed. H8's

Review round 1: a have naming no build in a phase but running is also written for a

On novox (2026-10-31) postgres's repeat backup was interrupted by the node-engine's
restart: its held have named no build, so the node's own composition took postgres in
and was refused for its secret reader, and nothing ran the backup again. Issue 1289
(R4c, its delivery held).
- A held have names what runs: read from the module's have before backing-up when
the agent has no running entry, as the not-composed mark does.
- A have in any phase but running that names nothing is not run inside the node's own.
- A backup interrupted by the agent's stop is no failure: the next start backs the
module up again and applies while the want asks a backup. A real failure stays
held for the operator's answer.
Quick fix: a new backup ask by hand. Thorough, chosen: the fault fixed where it lives
in the node agent, so every data module's interrupted backup resumes by itself.

Every put under want.<node>.>, every module's take-in and every placement write
made a pass, and each pass asked the vault for the node's own secrets. The
shadow's change check moves onto the composer, gains the want (by its
fingerprint, the only part composed) and serves both loops.
On the bus node restic's manifest replaced its process measure by awake (mesh-catalog 35ff67bd). The record of restic.measure was the node's, made while restic was folded, so restic's own apply never saw it, and the guard against removing a placed module's resources refused the node's own apply whole every two minutes from 2026-10-30 19:42: nothing of the node's own applied.
Quick fix considered: forget the one record by hand (a hand act on the node; refused). Thorough fix (this): the node's own apply keeps such a record and says so, never refusing or removing it; a module's own apply owns a node record whose id names it, so it alone removes it once neither composition declares it.

The verb compose has no warrant (ADR 0563 §2): Agent.Retry released a module held for a failed backup and re-applied
one already running its want. RetryFailed tries again only a failed apply not held, and refuses in words otherwise.
A hand ask no longer restarts the growing bound, and a pass less than askedWithin old is the answer, so a caller in a
loop drives no passes against the vault. A composer whose loop ended refuses at once. The retry line said try N+1.
The test's first shadow now ends before slowAfter is set, a race the race detector found under the new timing.
On 2026-10-31 ace's route-proxy said only that the vault could not be asked, and ace said nothing for five minutes
while a pass waited after the vault restarted; the retry that already existed was invisible. A refusal for a seat or
a read that did not answer now says when the node composes again ("the node composes again at HH:MM:SS (try N)"), a
retry pass says it starts, a pass that runs on says every minute what it waits on, and the node-engine's verb
compose makes a pass now and says how it went, so a person recovers without a restart.
