Problem

Orchestration commands and lifecycle services still use reusable Effect.gen wrappers. They should expose named operation spans while repeated event construction, provider-event bookkeeping, and idle worker probes avoid unnecessary spans.

Change

Replace 98 generator wrappers in orchestration commands and lifecycle services with named Effect functions. Keep repeated event construction and the worker's idle probe untraced, and preserve recursive return types, optional arguments, error mapping, and cancellation behavior.

Tracing choices

  • The rollback lease wrapper and dispatch lock wrapper use Effect.fnUntraced: their inner effects retain the existing orchestrationV2.checkpointRollback.execute and orchestrationV2.dispatch.withReceipt spans.
  • Named Effect.fn covers commands and run, thread, and session lifecycle operations, including startup, interruption, and rollback.
  • Effect.fnUntraced covers repeated event construction, pending-event projection, delivery bookkeeping, and session-liveness checks. The worker’s runOnce idle probe and scheduleIdleReleaseInternal, called on provider events, stay untraced to avoid spans for routine polling and event traffic. trackChildLifecycle, the delegated-question reactor's handle, and waitForThread's local outcome helper also stay untraced because they run per provider, domain, or matching stored event.

Scope and approval

This is a maintainer-requested layer of the Effect function migration. The maintainer explicitly requested the migration and this PR stack. It updates tracing boundaries in existing operations while preserving their operational behavior, rather than adding a product feature or default. The work is authored by juliusmarminge (maintainer list); there is no separate public approval discussion.

Depends on #21994.

Verification

The server typecheck passed. Ten focused suites passed: 324 tests covering startup, interruption, rollback, session lifetime, run execution, and thread control.

The additional per-event tracing fixes passed 102 tests across RunExecutionService, ThreadManagementService, and Orchestrator control reads, plus targeted lint and the server typecheck.

Nonvisual refactor; evidence comes from the focused behavior and tracing tests. No UI verification applies.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a cross-service Effect tracing refactor that preserves existing orchestration behavior while naming reusable operations and avoiding spans on hot event and polling paths. It adds no product capability, schema, default, deployment, security, billing, or static-analysis configuration change.

Needs human approval because:

  • Per-review cost limit exceeded (workspace setting). Approvability relies on correctness review in order to determine eligibility

Review your spending limits in Billing settings, or comment @macroscope-app review this PR to bypass the limit and review now. You can add or adjust custom eligibility rules. Learn more.

📝 Walkthrough

Selected effect-producing functions across orchestration-v2 now use Effect.fn or Effect.fnUntraced. The refactor preserves the described control flow and error handling, with some mappings moved into effect function handlers.

This change only adjusts tracing in orchestration services. Rollbacks and dispatch commands now record an extra span on top of the span they already had. That increases trace volume but does not change behavior. The PR is mergeable, ideally after removing the duplicate spans.

Use Effect.fnUntraced for trackChildLifecycle. It runs once per provider event.

trackChildLifecycle is called in the Stream.tap handler at Line 1297. That handler runs for every routed provider event, which includes streaming turn_item.updated and message.updated updates. With Effect.fn("RunExecutionService.trackChildLifecycle"), every event in a run creates and exports a span. These spans are children of the long-lived detached ingestion fiber. The result is high trace volume and allocation overhead on the event hot path.

This conflicts with the PR objective to keep repeated per-event work untraced. It also conflicts with the documented rule for per-event and per-chunk helpers. Change the helper to Effect.fnUntraced and add a comment that gives the reason. finalizeRootRun is guarded by rootRunFinalized, so it can stay traced.

Use Effect.fnUntraced for handle, because it runs for every domain event.

start passes handle to Stream.runForEach(engine.streamDomainEvents, handle) at Line 173. With Effect.fn("DelegatedTaskQuestionReactor.handle"), the server now creates one span for every domain event on every thread. Most of those events do nothing: they return at once at Line 66 or Line 104–106. The result is many empty spans in a busy event stream. That costs CPU and trace storage, and it buries the useful traces.

The path instructions say to use Effect.fnUntraced "for per-event/chunk work". The PR description also says per-event work stays untraced. Keep the catchCause handler as it is. If you want a span, add it only around the branches that do real work, after the early-return filters.

Use Effect.fnUntraced for the outcome helper.

outcome runs once per matching stored event in Stream.mapEffect (Line 912–916). It also runs for the initial read and the final read.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Keep scheduleIdleReleaseInternal untraced. The event pump calls it for each provider event.

startEventPump calls touchActivity(..., { providerActivity: true }) for every provider event except command_output.delta (Line 1964). touchActivity then calls scheduleIdleReleaseInternal (Line 1267). With Effect.fn, every streamed delta, item update and node update now opens and closes a span.

The pump fiber starts from open and forks into layerScope. Each per-event span can therefore attach to the long-finished open call as its parent. In addition, each forked releaseIfStillIdle span becomes a child of a span that has already ended. On busy turns this produces a large number of spans and very large traces.

The path instructions require Effect.fnUntraced for per-event work and require a documented reason. The stack also states that per-event helpers stay untraced.

@juliusmarminge Thanks. scheduleIdleReleaseInternal now uses Effect.fnUntraced, and the comment documents the per-provider-event rationale. This addresses the finding.

JJulius Marminge9d ago

Addressed the three additional per-event tracing findings in 4c87b06: trackChildLifecycle, DelegatedTaskQuestionReactor.handle, and the local waitForThread outcome helper now use Effect.fnUntraced, with their call frequency documented. Lifecycle operations such as finalizeRootRun and waitForThread retain their named spans. The earlier scheduleIdleReleaseInternal fix remains in place.

All 102 tests across RunExecutionService, ThreadManagementService, and Orchestrator control reads passed, along with targeted lint and the server typecheck. The dependent layers are rebased and pushed; their whitespace-ignored diff snapshots are refreshed. Macroscope's correctness review remains skipped by the configured per-review cost limit; the limit was not bypassed.

Remove the duplicate span on dispatchWithReceipt.

dispatchWithReceipt is now Effect.fn("Orchestrator.dispatchWithReceipt"). It wraps dispatchWithReceiptEffect, which already has the span orchestrationV2.dispatch.withReceipt (Line 11306). That inner span already contains orchestrationV2.dispatch.once.

Every OrchestratorV2.dispatch call now emits one more span. That span repeats the receipt span. The only extra work it covers is waiting for the thread lock and the optional parent lookup. This is the hottest path in the orchestrator. The group middleware already traces RPC callers.

The effect-services guidance says: "Preserve existing span names and options rather than adding duplicate spans." Use Effect.fnUntraced here. If you want lock wait time in traces, give the span a name that says so, such as orchestrationV2.dispatch.lock. Then it does not read as a second dispatch span.
