CI failed with: SyntaxError: Export named 'spawnSync' not found in
module 'node:child_process'. Root cause: pr-merge-github.test.ts (and
other test files) call mock.module('child_process', ...) which leaks
across bun's shared test-runner module space. The mock only exports
execSync, so when this integration test imports spawnSync without
the node: prefix, it resolves to the partial mock and the import fails.
The node: prefix forces explicit Node built-in resolution, bypassing
the mock. This is the correct fix per Bun's mocking documentation.

Summary
Third hotfix attempt for the kahuna→main blocking integration tests. CI failed with:
Root Cause
Other test files (notably
pr-merge-github.test.ts) callmock.module('child_process', () => ({ execSync: mockExecSync })). This mock leaks across bun's shared test-runner module space. The mock only exportsexecSync, so whencli-flag-shapes.test.tsimportsspawnSyncfrom'child_process'(no prefix), it hits the partial mock and the import fails.This explains why local tests passed (test ordering happened to load the integration test before the mock was registered) but CI failed (different test order).
Fix
Use the
node:child_processprefix which forces explicit Node built-in resolution and bypasses bun's module mock layer.Tests
