Where the engine does not answer the verb, the node's record is read once in its place, said in the journal (the fallback until every counted engine serves the verb). Kept in the state engine-reads, which assigner_engine_reads lists and asks again.

The assigner reads the indexer's module graph (a new reads line): of what a module invokes it waits only on the edges
the graph keeps and another module serves, so a left-out cycle holds nothing; a verb counts as served once a running
healthy build's manifest serves it. The hold is under the provisions' rule, its words naming the verb, since no reader
knows a rule number of its own yet. Without the graph no want waits on a verb.

ADR 0593 §7, §8: the check's composition, its compose asks to the Go build seat and the state
compositions go (the checker asks the engines); a proposal is judged without frombus; mesh-wants.upgrade
compare reads every node's composed-<node> through mesh-host.composed. The assigner no longer imports
compose, composer, frombus or buildrun.

ADR 0590 clause 3 ends the choice of a condition source by the keeper's
take-over key, which mesh-sdk no longer defines. The assigner watched
that key and said every condition straight to the router while it named
the controller. It now writes each as a finding the keeper carries, and
says one straight only where it has no findings bucket at all.

The controller ended by its unassignment (ADR 0590) and mesh-sdk drops
its seat, the grants seat and placement's adopt and hand-back. The
indexer's judge still carried the controller's seat entry, the old
removal words and the two placement verbs, and counted 58 seats; the
checker still placed mesh-controller beside the node-engine's and the
catalogue's tests and failed a node-engine check without its trunk; the
assigner still asked a compose of the running controller, served adopt
and hand-back as stubs, and kept a policy-split finding that could no
longer arise.

The controller's placement-export is no longer called, its answer reader, the seed and the hand-back flow of the holder are
removed, and a seed or hand-back proposal a previous process left open ends at its next pass.
Tests: the adopt, hand-back and seed cases of the seat's verb test and of Propose are replaced by one gone-case; the export
reader's table and the seed test go.

mesh-controller.composed leaves the reads and the watches; upgrade compare lists the node composition digests of the haves
instead of comparing with the controller's policies, which the controller no longer writes.

Every handed-away branch is the only one: world.assigned is the placement, the pair comparison and its conditions go, the
lease and assignments buckets are no longer opened, watched or declared, and a proposal of any kind is taken.
Tests: the pair-comparison test and the controller-composition record-ask test are replaced by one placement test; the
rest are edited to place their modules instead of assigning them.

Drops callAll, the refused-call conditions and the pin reads; the conditions a previous process raised are cleared once.
Tests: deletes four (the refused-call condition, its clearing, the contract of the calls, the condition's shape) and adds one.

Why: from the lease write the grants part's state grants is the source and the controller's bucket otherwise; the assigner follows the lease key (a pass only when the source changes), and neither bucket stops its start. Needs the group's mesh-sdk pin (GrantSource, LeaseHandedAway, the assigner a named reader of the lease).
One commit for the branch feat/1126-nodes-compose of mesh-delivery: its 16 commits squashed so its history does not carry the 17.8 MB compiled mesh-delivery-assigner a commit added by mistake and a later one removed (issue 1577). The tree equals the former head ff6c038d. The operator allowed this rewrite of the feature branch on 2026-10-26.
The assigner reads mesh-controller.builds again (the composer's runningCommits reads the build record of every open
assignment), puts its compose asks on node-build-go and says its conditions on operator-channel.
