Motivation

• Local execution's $.Actions validation, JSON checks and $.Actions proxy live in local-execution.ts, which installs a globalThis.$ accessor when it's imported.
• A separate process that runs a backend function needs those checks without that import-time side effect.
• Ticket: APPS-2961 Run local backend functions in parallel, with per-call realtime console logs.
• Stack order, merged bottom up:
  1. [APPS-2961 Refactor: move local execution's side-effect-free helpers into their own module]([APPS-2961] Refactor: move local execution's side-effect-free helpers into their own module #604) (this PR)
  2. [APPS-2961 Update: run each local backend function call in a fresh sandboxed process]([APPS-2961] Update: run each local backend function call in a fresh process #608)
  3. [APPS-2961 Update: run local backend function calls in parallel, with per-call log prefixes]([APPS-2961] Update: run local backend function calls in parallel, with per-call log prefixes #603)

Changes

3 changes across local-execution-shared.ts and local-execution.ts

What changed	File
Moves the $.Actions validation, serializeActionInputs, assertJsonRoundTrippable and makeActionsProxy, unchanged, into a module with no import-time side effects.	local-execution-shared.ts
makeActionsProxy takes a dispatch callback, so its caller decides where a call goes.	local-execution-shared.ts
Imports the moved helpers and passes the in-process dispatch to the proxy.	local-execution.ts

QA Instructions

• CI: Continuous Integration run for 144ff8af

yarn typecheck:all
# Expected: exit 0 ✅ VERIFIED
yarn lint
# Expected: exit 0 ✅ VERIFIED
yarn cli integrity
# Expected: exit 0, no changes ✅ VERIFIED
TMPDIR=/private/tmp yarn test:unit packages/plugins/apps
# Expected: Test Suites: 39 passed; Tests: 906 passed, the existing local-execution tests unchanged ✅ VERIFIED

• TMPDIR=/private/tmp is only for the macOS manifest-tags and parameters suites, which fail under /var/folders on master too.

Blast Radius

• No feature flag: a pure move, with no behavior change.
• Low risk: only local-execution.ts imports the moved code, and its tests run unchanged.

Documentation

• APPS-2961 Run local backend functions in parallel, with per-call realtime console logs

No open issues 🎉

What changed in this PR

Extracts reusable local-execution helpers into a side-effect-free module, preparing for sandboxed backend calls without changing current behavior.

Changes:

• Moves action validation, JSON checks, and proxy creation into a shared module.
• Injects a dispatch callback while preserving existing in-process execution.

File	Description
packages/​plugins/​apps/​src/​vite/​local-execution.ts	Imports shared helpers and supplies guarded dispatch.
packages/​plugins/​apps/​src/​vite/​local-execution-shared.ts	Exports reusable helpers without installing the global $ accessor.
