Problem

The provider registry tests copy an ES-module Claude CLI fixture into the user's home directory with the extensionless name claude. If an ancestor package.json declares type: commonjs, Node no longer runs it as the intended ES module. The existing readiness test then reports Claude as warning with a null version instead of ready with 2.1.219.

Change

Keep the .mjs extension when copying the fixture, and declare type: commonjs in the temporary fixture directory so the existing readiness test catches a filename regression regardless of the developer’s home configuration. The script contents, configured tilde-path coverage and production provider code are unchanged.

Scope and approval

This qualifies for CONTRIBUTING.md's small, focused obvious-bug exception: preserving the fixture extension fixes execution under a CommonJS home directory, and the fixture-local package declaration makes that condition explicit in the existing tests. No feature, setting, product default or contract changes.

Verification

Based on main 09a54f01bc0ae83865347a965ced50f8c8ec2953, macOS arm64, Node 24.13.1:

• With an explicit type: commonjs package in the temporary fixture directory and only the filename reverted, the existing runs Codex and Claude readiness probes from configured tilde paths test fails: expected { status: "ready", version: "2.1.219" }, received { status: "warning", version: null }. It passes with the fix; no assertion was changed.
• A direct subprocess check copies the exact same fixture bytes into an isolated directory containing {"type":"commonjs"}:

  ./claude --version      -> no version output
  ./claude.mjs --version  -> claude 2.1.219
  

• vp run check:changed 09a54f01bc0ae83865347a965ced50f8c8ec2953 passes formatting, lint, both knip checks, GraphQL generation, three affected package typechecks and 27 tests in two files.
• Scoped vp check passes; root vp run typecheck passes all 40 packages.

This verifies the executable test fixture and server test path, not a real Claude model turn or Windows execution. The existing script-based fixture tests already exclude Windows.

Full details: Title check

Explanation

The title "test(server): keep the Claude probe fixture executable in CommonJS homes" matches the single main change: the copied Claude CLI test fixture keeps its .mjs extension so Node runs it as an ES module under a CommonJS package.json. It is a short, conventional-commit style title that a teammate scanning history can understand. The 72-character length is acceptable.

Full details: Description check

Explanation

The description follows the repository template closely. It has the Problem, Change, Scope and approval, and Verification sections, and each section is filled in with specific detail. The Problem section explains the failure mode (an extensionless ES-module fixture run under a CommonJS ancestor package.json) and the observed versus expected readiness results. The Change section states the rename to keep the .mjs extension and the fixture-local type: commonjs declaration, and says the script contents, tilde-path coverage and production code are unchanged. The Scope and approval section invokes CONTRIBUTING.md's small obvious-bug exception and explains why it qualifies. The Verification section gives concrete before/after test results, a subprocess check, and the commands run, and it states what was not verified (real Claude model turn, Windows). The template asks for the model and harness at the end, and the description includes that line.

Make the CommonJS condition part of the fixture.

Write a package.json with "type": "commonjs" in fixtureDir. Without it, Node can detect the extensionless fixture as an ES module, so the existing readiness test can pass with the old filename. (nodejs.org)

As per path instructions, “request a missing test only when it would catch a real regression”; this setup makes the existing test catch the reported failure.

Verified in a real dev environment

Verified as-is at 32f316332066b0899f9c18547b656b2c2ed0c189 on this Linux VM. No source changes or pushes.

This PR changes only the existing provider registry test fixture. There is no changed production app behavior. I verified the fixture regression separately and exercised the real app for nearby regressions.

• On github/main (331889a13560), the existing configured-tilde-path readiness test fails with an isolated CommonJS home: Claude's version subprocess exits 1 and readiness is error instead of ready.
• At the exact PR head, all 25 provider registry tests pass under the same CommonJS condition. Blacksmith vp run check:changed 09a54f01bc0ae83865347a965ced50f8c8ec2953 passes format, lint, both knip checks, GraphQL generation, three package typechecks, and 27 tests in two files.
• Installed dependencies and ran main and PR dev servers sequentially. Used repo Playwright with /usr/bin/google-chrome, created the real repository project through the UI, selected Codex gpt-6.1-sol, and submitted an actual turn. Both main and PR returned provider verification ok.
• On the PR, a follow-up asking for the previous phrase returned the same phrase. Both responses survived reload. Settings provider refresh reports Codex v0.164.0 available and the actual installed Claude v2.1.321 not authenticated. Setting the real Codex binary to ~/.local/bin/codex also remains available and persists across reload.

Short command transcript

Not verified

A real Claude model turn: this VM has no Claude login. The passing 2.1.219 fixture assertion proves the test correction, not a real Claude session. Native Electron, iOS/Android, macOS/Windows, and remote/tunnel paths were not exercised.
