jschoubben b8158affa7 compose-candidate is answered off its subscription, so its bound counts from the ask
mesh/delivery closed: a newer head of the same pull request
mesh/check failed: novox: not composed on novox: these assignments cannot be applied: | b8158affa7af on 27a956448c0a
An endpoint's subscription hands its asks over one at a time: two checks asking
one node at once queued, and the second answered at about 100 s, past the
checker's bound and the bus's one-minute reply window. compose-candidate is now
answered in a goroutine of its own, at most four at once, one more refused in
words. The new cases are rows of the existing tests (test budget).

Issue 1126, review round 1.

jschoubben ebb4f4af18 compose-candidate reads each manifest once and answers within the bus's reply window
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.

Issue 1126.

jschoubben 0bbdae1d9d compose-candidate reads the indexer's candidate by its group key, not the check's key
mesh/delivery merged: source.main moved to novox/mesh-host@27a956448c0a
mesh/check checking 0bbdae1d9dfb on 27a956448c0a
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.

jschoubben f6bda12a32 The node whole publishes its compositions and answers a candidate (H6)
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.

jschoubben 3fa41dfe1a Serve node-engine.compose-candidate from the node's shadow (H4)
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.
