The engine's Composed keeps the catalogue's Plan and the declaration types and goes through nodeengineclient's codec; the fingerprint key part is meshcatalogclient's. The candidate answer is nodeengine.CandidateAnswer; the have still holds it through an interim JSON bridge (link.interimAnswers) until the Have group moves.

While the indexer holds distribution's new manifest, every node reads main's,
which claims only mesh-artifact-store: a new engine must find the store there.
Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
The provision artifact-store retires, so the store is found by the holder of
container-image-registry and the listen it opens to the mesh, on the port its
node put it on; every name of the store, oci-artifact-registry's too, answers
that address. The engine states form:seat-reach with its contract.

The group's mesh-build-go requires go-package-registry, which the forge
now provides; the stand-in listed the forge's offers by hand and missed it,
so the test failed against the group's catalogue. It now takes them from
the catalogue's gitea manifest, so a registry the forge gains needs no edit.

mesh/check failed (7): shanks: novox/mesh-catalog#612 does not merge into the trunk: files in conflict: mod…; and 6 more | 32c5df952cbf on e73aae3686a6
mesh/delivery-group group feat/registry-milestone rejected: composed together: the checker's verdict at the members' heads (068b7d23cf1a): shanks
The store's front is distribution's program, a bundle the mesh builds, so nothing serves it before the builder: the
bootstrap's /v2/ wait and its pushes now go to the loopback port the store's manifest publishes, as the publish contract
allows on the store's own node. The one-off credential and its file go: the runtime could not carry it on a push, and no
push needs it. The tags list is asked for the repository being published, not always the control plane's.

waitIdle returns once every change sent to the loop is taken in and applied and no backoff wait runs, so a retry the
clock or a wrong settled would start is counted, with no real sleep.

The owner is the account the manifest names for the directory that holds the file; the bootstrap no longer makes that
directory itself, and a run that reaches it first is refused naming what it waits on.

The image, the seat and its holder, when the pull began, and the last retry with what triggered it ride in the failed
have's pull-wait (mesh-sdk delivery.Have.PullWait, asked of the lead in j1-sdk-requests.patch), from the agent through
the link's module fact to the have bucket; the agent's own read view of them goes with the verb. Rows in the agent's
pull test and the have bucket's test; each failed without the code.

ADR 0627 §1, §4: mesh-sdk keeps no asks, asker, vault answers or compose-candidate checks, so the node-engine takes them
from mesh-contracts: operator-channel's contract and client (asks, warrants, the asker's client), mesh-vault's sign verb
and answer, and node-engine's own contract and client for compose-candidate's ask, answer, verdicts and bound. The
lead's ruling on pull-waits (no record gives the seat that verb): the verb and its handler go; the row that read the
waits now holds the seat refusing the verb, and failed before the change. The go.mod requires of mesh-contracts' modules
come with the group's pin.
Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
mesh-sdk's ComposeCandidateAnswer and ModuleComposed are now the generated nodeengine types (ADR 0613 §3, §5), so the
input sent for the checker's sandbox is decoded once into the object the contract carries, its numbers kept as written
(json.Number), and its size still counted from the bytes it was marshalled to.

The verb's answer and the event's body are mesh-contracts' nodeengine types, not mesh-sdk's, and the seat's verb and event
names are the contract's. The two reasons of the event, started and returned, are the engine's own words beside it.
Requires mesh-contracts and the registry milestone's mesh-sdk (a go.work, uncommitted, until the group pins them).

mesh/check being carried to e2380404a1fa on e73aae3686a6 | from 998d8f737008
nats on novox, 2026-11-04 11:07: after mesh-host #207 the module stayed held
although its want carried "Back up again", and the engine said nothing. The
engine's composition verb showed it running what its want names (taken from
its held have at the start), so when the answer was in a revision of the want
read after the hold, settleOne returned on "it runs what the want names"
before it looked at the hold: the answer was swallowed, silently. The start
path #207 fixed was right but never met; no test ran the live shape.
- settleOne: the hold is looked at before what runs. An answer (again or
skip) in a want revision after the one the hold took is acted on whatever
runs; with no answer the hold is kept and said with both revisions.
- baseline: the hold kept at the start is said (it was the silent branch).
- composition verb: the want as the engine holds it now carries self, backup,
words and its key's revision, beside the engine's attempt (held, answered
revision, want and composition revisions, transient) and whether the module
was looked at since the start, so which want the engine read is read, never
guessed.
Quick fix: answer once more by hand (a new want revision), which the guard
still swallows while what runs equals the want, so none exists. Thorough fix,
chosen: the order of the guards and the read tool, proved by rows of the live
shape (a self module of policy record, its held have naming the want's own
composition, the answer before the start, and again and skip arriving while
held); the two later rows fail with the old guard order.

The journal of an unpack sat at <target>.unpacked.json, in a directory
the module's account may write: a forged one would make the root engine
remove or adopt any path it named. It now lives under
<statedir>/unpacked/<sha256 of the target>.json, mode 0600, names its
target, and is refused whole when an entry is not filepath.IsLocal or a
parent is not above the target. It goes when the archive is taken off,
whether its state record still said what it unpacked or not.
The launcher's stop grace for a host on trial rises from 20 s to 75 s and
the unit's TimeoutStopSec is 120 s (openrc the same), past the host's own
60 s wait for the apply in flight, so neither cuts a save off again.
Tests folded as rows into existing ones (the repository is over its unit
budget): the journal's rows, a forged entry and parent refused, the
journal gone with a record that lost its Unpacked; the test that passed
on main dropped; the stop test waits on its own line, not a sleep, and no
longer consumes the save it waits for.

nats on novox, 2026-11-04: the operator answered "Back up again", the
engine restarted, and baseline() took the hold with AnsweredRev = the
want's current revision, so the answer in that very revision was never
acted on and compose refused "held for a failed backup".
Quick fix: answer once more (a new want revision). Thorough fix, chosen:
at baseline, a held module whose want carries again or skip is applied
(again backs it up first, skip goes on without one); a hold with no
answer stays held. The cost said in the code: an answer already acted on
before a stop, whose backup failed again, is tried once more per start.
Claude-Session: https://claude.ai/code/session_01JG73KG7AfSdh6FP8VrBqCn
On novox the node-engine's state had lost the records of nats's two
archives, which only a temporary save file of 2026-10-24 still held, and
about 260 such files (~80 MB) lay beside it. The cause: an apply runs
detached from the engine's stop (applyContext, WithoutCancel), and
runLink returned, and the process ended, without waiting for it; a save
cut between its write and its rename left its temporary file and the
state before it, and whatever the apply did was never recorded.
Quick fix: remove the leftover files by hand and restore the records.
Thorough fix, chosen: the engine ends between applies whichever way it
ends (a stop, standing aside, a move to another bus): it waits up to 60 s
for the apply in flight, then lets no save start (store.Quiesce). Save is
one writer per process, flushes the directory after its rename, and says
loudly each record the state saved before held that this save drops and
nothing forgot (Forget, Release mark what is dropped on purpose, and no
longer write into an array an earlier copy reads). The engine's start
removes leftover temporary saves under the apply lock and says how many.
