Problem

Reusable client operations still use Effect.gen wrappers across web, desktop, mobile, and client-runtime. They should have named operation spans while batching, recurring samples, streamed updates, and input-dependent WSL tracing retain their intended boundaries.

Change

Replace 53 reusable generator wrappers across web, desktop, mobile, and client-runtime. Preserve input-dependent WSL span attributes, explicit result types, and command input inference; keep shell-cache batches, telemetry samples, and repeated scheduling helpers untraced.

Tracing choices

Named Effect.fn covers reusable client-runtime commands, authentication and linking, filesystem work, and desktop operations across web, desktop, and mobile.
Effect.fnUntraced covers shell-cache batches, repeated command scheduling, metadata seeding on file reads, broadcasts of streamed updates, and periodic telemetry samples. These run per batch, command, read, update, or sample.
The untraced resolveWsl wrapper still creates its existing explicit span, preserving request-dependent port and distribution attributes. Untraced here avoids a second wrapper span; it does not remove the intended WSL tracing.

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 #21997.

Verification

Scoped typechecks passed for web, desktop, mobile, and client-runtime. Focused suites covered cloud linking, authentication proofs, client caches and commands, desktop backends, updates, WSL, and telemetry. The affected desktop and command suites were rerun after the final fixes.

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

📝 Walkthrough

The pull request converts Effect implementations across desktop, mobile, web, and client runtime to named or untraced Effect.fn forms. It also extracts pull-request actions and diff loading, and adds shared earlier-thread-history loading.

Changes: Effect Function Refactor

Layer / File(s)	Summary
Desktop Effect conversions `apps/desktop/src/app/`, `apps/desktop/src/backend/`, `apps/desktop/src/electron/ElectronWindow.ts`, `apps/desktop/src/preview/Manager.ts`, `apps/desktop/src/snapShot/DesktopSnapShot.ts`, `apps/desktop/src/telemetry/DesktopTelemetryPublisher.ts`, `apps/desktop/src/updates/DesktopRemoteUpdates.ts`, `apps/desktop/src/wsl/*`	Desktop operations now use `Effect.fn` or `Effect.fnUntraced`. Existing validation, polling, cleanup, telemetry, update, snapshot, preview restoration, and WSL behavior remain unchanged.
Mobile agent registration `apps/mobile/src/features/agent-awareness/remoteRegistration.ts`	Registration, unregistration, token handling, and live-activity reconciliation now use `Effect.fn`. Existing platform checks, relay calls, and retry behavior remain unchanged.
Mobile cloud proof and linking `apps/mobile/src/features/cloud/dpop.ts`, `apps/mobile/src/features/cloud/linkEnvironment.ts`	DPoP key and proof operations and cloud linking now use `Effect.fn`. Existing key handling, proof creation, relay flow, and error behavior remain unchanged.
Web cloud operations `apps/web/src/cloud/dpop.ts`, `apps/web/src/cloud/linkEnvironment.ts`	Browser DPoP and cloud-link operations now use `Effect.fn`. Existing proof, relay, link, unlink, and error behavior remains unchanged.
Web connection persistence `apps/web/src/connection/storage.ts`	Shell, server configuration, thread, and VCS reference persistence operations now use named `Effect.fn` generators. Encoding, persistence, and error mapping remain unchanged.
Client runtime Effect conversions `packages/client-runtime/src/platform/shellCacheEncoding.ts`, `packages/client-runtime/src/relay/managedRelayState.ts`, `packages/client-runtime/src/state/*`	Encoding, relay observation, authorization, metadata, orchestration, persistence, and scheduling operations now use `Effect.fn` or `Effect.fnUntraced`. Their existing behavior remains unchanged.
Client runtime command effects `packages/client-runtime/src/state/pullRequests.ts`, `packages/client-runtime/src/state/threadCommands.ts`	Pull-request diff loading and action execution use shared effects. Earlier-thread-history loading returns `"noop"` when no controller is registered and otherwise delegates to the controller.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This broad refactor mainly standardizes Effect function wrappers and tracing boundaries while preserving existing operational logic. It also touches DPoP and environment-authentication code, which requires human review under the security-sensitive change policy.

Notes:

Diff unchanged. Approvability was decided on eligibility alone.

No code changes detected at 8195e72. Prior analysis still applies.

Use the PreviewManager. span prefix for restoreControlSession.

AGENTS.md requires reusable Effect functions to use stable Effect.fn("Service.operation") span names. restoreControlSession belongs to PreviewManager, but its span uses Manager.restoreControlSession.

✅ Confirmed as addressed by @juliusmarminge

JJulius Marminge9d ago

Fixed in b31222dc91: the span now uses PreviewManager.restoreControlSession, matching the service and its other operations. Targeted lint and the desktop typecheck pass.

CcoderabbitaiBot9d ago

@juliusmarminge Thanks for the fix. PreviewManager.restoreControlSession now matches the service’s span prefix.

✅ Review thread resolved.

makeIsAvailable now creates a span, but its invocation still has Effect.withSpan("desktop.wsl.isAvailable") at line 1154. Could you use an untraced helper here so the existing named span remains the sole tracing boundary?
