refactor: simplify control-plane persistence wiring - #2559
Merged
Conversation
📝 WalkthroughWalkthroughThe change replaces direct persistence and service construction with shared stores, scheduler dependencies, DAG loaders, run-state stores, workspace contracts, and injected monitor state. It also propagates parallel-item metadata through queued, distributed, local, retry, and child-run execution paths. ChangesShared dependency architecture

Inline comments:
In `@internal/cmd/context.go`:
- Around line 544-567: The NewScheduler guard validates c.Stores.DAGSettings
while scheduler.New consumes schedulerDeps.DAGSettingsStore. Update NewScheduler
to validate the consumed DAGSettingsStore value or explicitly assign
deps.DAGSettingsStore from the correct persistence store before constructing the
scheduler, ensuring the existing nil protection covers the dependency used by
scheduler.New.
- Around line 510-521: Update Context.NewCoordinatorClient to return both the
coordinator.Client and an error, propagating clientConfig.Validate failures
instead of logging and returning nil. Update all server, scheduler, and CLI
startup callers to handle and return the error so enabled but invalid
coordinator configuration fails startup; preserve nil-client behavior when the
coordinator is disabled.
- Around line 221-231: Update NewContext so the remote-context branch executes
before newFileStores, avoiding local store initialization for remote commands;
retain the existing newEventStores path for remote contexts and the current
newFileStores setup for local contexts.
In `@internal/cmd/coord.go`:
- Line 230: Update the coordinator handler setup to obtain runtime stores via
ctx.runtimeStores() instead of newExecutionStores(ctx.Context, cfg), then assign
that shared runtime store bundle to the handler fields corresponding to the
coordinator’s stores and secret store so the c.Stores.Secret override is
preserved.
In `@internal/runtime/builtin/dag/enqueue.go`:
- Around line 189-195: Update the dependency error messages at
internal/runtime/builtin/dag/enqueue.go:189-195 so the missing context reports
that dag.enqueue requires a SubWorkflowRunner implementing executor.Enqueuer;
update internal/runtime/builtin/chat/tools.go:62-64 so non-local tool DAG
loading reports that DAGLoader is required. Use the existing symbols
SubWorkflowRunnerFromContext, executor.Enqueuer, and DAGLoader.
- Around line 244-250: Preserve ParallelItem independently from Params when
queuing and restoring parallel sub-DAG runs. Thread it through
executor.RunParams, executor.EnqueueRequest, all enqueuer and agent paths, and
sub-run conversion, then persist it as parallelItem,omitempty in ir.SubDAGRun.
Ensure buildChildRunParams retains the item even when subDAG.Params overrides
item-derived parameters, and add a regression test with explicit parameters that
do not reference ${ITEM}.
Apply the same fix in `@internal/runtime/executor/subworkflow.go` around lines 28
- 35: This site identifies the missing request field required to preserve the
same parallel-item state.
In `@internal/service/coordinator/config_test.go`:
- Around line 16-36: Add a separate test for ConfigFromPeer using a zero-valued
appconfig.Peer, asserting that MaxRetries and RetryInterval retain their
defaults and that Insecure has the expected unset-peer value.
In `@internal/service/coordinator/subflow/local.go`:
- Around line 252-261: Update Enqueue’s FindAttempt error handling to treat
dagrun.ErrNoStatusData the same as dagrun.ErrDAGRunIDNotFound, allowing the
existing-run result path to proceed with the default queued status. Preserve the
fatal error path for all other errors, and change the later intake.EnqueueRun
assignment from := to = so the existing err variable is reused.
In `@internal/service/coordinator/subflow/router.go`:
- Around line 69-77: The Router.Enqueue path must use the same runner-selection
policy as execution rather than choosing the first Enqueuer. Update the
routing/admission contract and related runner interfaces to expose the request
fields needed by ShouldRun, then route enqueue admission through that shared
selection logic while preserving the existing no-match error. Add coverage for
distributed execution and WorkerSelector behavior, anchoring changes around
Router.Enqueue, NewSubWorkflowRunnerFactory, and runner ShouldRun
implementations.
In `@internal/service/coordinator/subflow/runner.go`:
- Line 33: Update the error message assigned to errNoRunStateStore to replace
the inaccurate “database” wording with “run-state store,” while preserving the
existing error behavior and symbol.

Summary
internal/cmd/processpackage and into their owning servicesWhy
The command process package had become an intermediate composition layer shared by unrelated services. That obscured service ownership, duplicated configuration mapping, and made future control-plane separation harder. This refactor keeps the CLI as the application composition root while each service owns its constructor and file-backed adapter.
The change intentionally preserves the existing file-backed behavior and persistence contracts. It does not add a new storage backend or alter runtime storage formats.

Refactors control‑plane persistence wiring and isolates runtime from control‑plane repositories while preserving file formats and startup policies.
