 | L5 | Control records leave the controller, and the controller is not changed (ADR 0565): mesh-config keeps each module's declared config in its state `declared` and publishes the predefined keys, which the indexer reads from the forge bridge's messages with each open pull request's config candidate; config switches to that source only on the operator's take-over, refused while `compare` shows a difference; each node agent writes its node's declared packages (the node seat `node-engine`, verb `packages`); the assigner holds the new seat `mesh-wants` with the upgrade policy a person chose and the bus step; the hand-act log (`hand-act`, `hand-acts`, `warranted`) is the stream of the new seat `mesh-hand-acts`, held by a new module in mesh-catalog, which every recorder calls from this delivery with no switch; the checker and the assigner's composition check read the held values of their pull requests from mesh-config's state `kept`; from the lease write a trusted config value is set only on the operator's Approve; `settings`, `move-config` and `move-placement` end with the lease and nothing replaces them. each person's six policy choices are set through `mesh-wants.upgrade` and recorded as hand acts, `upgrade compare` and the assigner's finding `policy-split` show any split, and the lease write waits for `compare` to be empty (ADR 0565 §8). One delivery group, built before the lease write of L3, which waits for the group delivered, the six choices set, mesh-config's `compare` empty and its take-over done, `mesh-wants.upgrade compare` empty, and the readings of ADR 0565 §12 (ADR 0565 §14; ADR 0348 §9, ADR 0502 §2, ADR 0539 §14, §15, ADR 0547 §11) | — | mesh-sdk, mesh-catalog (mesh-config, mesh-hand-acts, pacman, the forge module, claude-code, mesh-knowledge, mesh-conditions, mesh-healers), mesh-delivery (indexer, assigner, checker, grants part, forge bridge), the node-engine (`mesh-host`); mesh-controller is not a member | 1953 |
 | L6 | Provisioning leaves the controller (ADR 0570): every provision is one key of the seat `mesh-provisioner`, held by mesh-provisioner, holding a reference and never a value, and each placed module's provisioning plan a key of its state `plans`, both composed from placement, the wants and the manifests on change events; each provider acts once all a provision depends on is provided; the assigner moves a want only once its build's provisions are provided; a provision no want needs is retiring, and its account or credential is removed only on the operator's Approve, its data never; the vault mints each provision's secret sealed to the consumer's and the provider's node, and the consumer's node-engine writes it; a wait for a person is a provision's state, which the watchman reads; bus permissions stay with the grants part (ADR 0349, ADR 0230, ADR 0547 §11) | — | mesh-sdk, the node-engine (`mesh-host`), mesh-tools (the tool runner's provisioner client), mesh-catalog (mesh-provisioner, the vault, the provisioner client, postgres, keycloak, gitea, route-adapter), mesh-delivery (assigner, watchman) | 1954 |
 | L7 | History and records leave the controller (ADR 0571): the builder keeps its build log, one entry at a build's start and one at its end, from which build history and durations are read and the module mesh-catalog asks the builds it missed; the artifact sweep is the seat `mesh-artifact-sweep`, held by artifact-store-tools beside the artifact store, its keep set from the store's own listing, the wants and the build log, sweeping at each build's end from the lease write and recording each deletion in the hand-act log; disk readings are disk-load's own state on every node; who holds which seat is the state `seat-holders` of the seat `mesh-placement`, and tools are found by the tool runners' announcements; what a node runs is its want and its have; the grants part writes `grants.<module>.<fingerprint>` and keeps memberships in its own state; root-free is a probe of the self-check; no manifest but the controller's reads, invokes or consumes `mesh-controller`, but a named list kept to the lease write, so the lease write's check passes (ADR 0189, ADR 0547 §11, ADR 0549 §6) | — | mesh-sdk, mesh-controller (its pin only), mesh-delivery (builder, indexer, assigner, grants part, view), mesh-catalog (artifact-store-tools, disk-load, the backup seat's holder, mounts, nfs-server, minio, mesh-watcher, the messenger, the self-check, the module mesh-catalog, docker), mesh-tools (the tool runner) | 1955 |
