Every caller composes through mesh-sdk's go/compose since issues 1386 to 1388; the controller's second copy of the composition is dead code. The parent of this commit is fb556d6b, whose try (build-1792493691274712799, 17m28s, 2026-10-20 11:12 UTC) ran the equality test green on the live facts: every machine was sent and compared both ways (ADR 0453, issue 1384).
Deleted, 40 functions: in plan.go planFor, declarationWith, renderingFor, grantsFor, theRestOfTheMesh and their helpers (boundOfGrant, busCredentialIssued, carriedBuilds, carriedOn, composeBusUsers, engineJudgesRoot, engineReadsHealth, engineTakesHanded, takesHanded, givenUnderAnOldKey, issuedToHolder, keyFor, licencesFor, managerPublicKeyFor, movedProvider, providerMoved, providerModuleOf, sayLeftOut, seatsOn, wireBuilds, zonesInTheMesh); in network.go generators, whoResolves, namesInTheMesh, onThePrivateNetwork; composedAndValidated, adoptionFor, adoptionOf, engineOpensVaultBox, namedModules, localNetworksOf, keepRecorded, passSeatsOn, theMeshPassesSeatsOn, assignmentsOf. Choosing (Reading, Allocating, Foreseeing) is gone: coreBoxesFor and coreBoxesOf take a plain allocating flag. composeForPush no longer takes the private network it ignored. The seat pass of a send is performSeatPasses, over the passes the composition names.
Measured: cmd/mesh-controller non-test code 67,643 -> 65,821 lines (-1,822), its tests 57,691 -> 57,286, with the integration part of the equality test removed here because it calls the deleted functions. Not the issue's 3,000: that counts all of plan.go (2,192 lines), of which the callers, the verbs, the perform step and the sends remain (sendable, recorded builds, the held-back and ready-node logic, the plan verb, the gate's trial); and the 37 functions a name walk lists as unreachable are called through interfaces and method sets and are kept.
Tests dropped, each with the mesh-sdk go/compose test that holds its cases:
- seat_pass_test.go TestACompositionWithTwoClaimantsRecordsNoneAndSaysSo, TestACompositionChangesNothingWhileTheHolderIsAssignedOrNobodyClaims, TestAHolderAssignedButNotOnTheShelfIsNotTakenForGone: rest_test.go TestNoSeatIsPassedForTwoClaimantsAnAssignedHolderOrNoClaimant, TestAHolderAssignedButNotOnTheShelfIsNotTakenForGone, TestASeatWhoseHolderIsAssignedNowhereGoesToItsOnlyClaimant. TestACompositionPassesTheSeatAndWritesOneHandActByTheController and TestALostPassWritesNoActAndAFailedOneLeavesTheRecord stay as tests of the send's step (performSeatPasses); TestAThrowawayMeshPassesTheSeatInMemoryAndWritesNothing stays as TestAThrowawayMeshWritesNoHandActForAPass.
- seat_pass_test.go TestNoSeatIsPassedWhenAMachinesAssignmentsCouldNotBeRead: no counterpart, and none is needed: the adapter reads every machine's assignments for the Input and a machine whose read fails fails the Input, so no seat is passed on a partial read.
- network_test.go TestOnlyAMachineOnThePrivateNetworkIsNamed: network_test.go TestANodeNotOnThePrivateNetworkGetsNoAddressAndNoNetwork.
- held_back_test.go TestASendCarriesTheCurrentBuildsAndALeftOutModuleKeepsItsOwn: node_test.go TestAModuleLeftOutKeepsTheBuildItWasLastSent (and compose_sdk_test.go's table, now literal).
- modules_wire_test.go TestTheBuildOfACarriedCommitIsTheAssignmentsOrTheOneBuiltFromIt: node_test.go TestTheBodyCarriesTheOrderTheInputGivesAndTheBuildsOnlyToAnEngineThatReadsThem.
- compose_equal_integration_test.go: the old path it compares against is deleted; its last run is the parent's try.
Rewritten against mesh-sdk, same cases: issued_test.go (needs now come from compose.Resolve: Needed.IssuedToHolder and ProviderMoved), module_health_test.go and merge_gate_handing tests (the contract in the Input), provisioner_account_integration_test.go (the composition's refusal), one_resolution_integration_test.go (sayFound). Every test of the send, perform, the adapter and the verbs is kept; the tests that used planFor, declarationWith, generators, renderingFor or grantsFor as setup use resolveNode, composeSend, composeQuestion, renderingOf and grantsOf. compose_callers_test.go now fails when any deleted name is declared or called again.
Committed by copying the files of a staging branch (stage/r4b-1389 at 198be8217c, built from fb556d6b by patch commits and compared with the author's worktree), so that this commit's parent is fb556d6b.
How each pair credential a node takes stands (held with its sealed consumer copy, the next send makes it, only a person's to give and nobody gave, or refused in the controller's words), the credentials made for each provider's consumers, the own secrets with their origin and key and value, the vault's kept boxes, the bus's users, minted users and memberships, the mesh's authority and each machine's serving key and kept certificate, the repositories built, the current builds and the build of each commit a machine that reads them is sent. A credential no row holds is not made (planFor made it in every mode): the adapter returns it as would-make for perform (issue 1385). New reads in the inventory (OwnSecretRows, PairCredentialState, BusMinted) and the identity (KnownAuthority, KeptCertificate) write nothing.
