Description

The initial concern was that throwing an error would be a breaking change, but it already throws an error when accessing name, for example:

beforeAll(({ name }) => {
  name.slice(10)
})

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

  • It's really useful if your PR references an issue where it is discussed ahead of time. If the feature is substantial or introduces breaking changes without a discussion, PR might be closed.
  • Ideally, include a test that fails without this PR but passes with it.
  • Please, don't make changes to pnpm-lock.yaml unless you introduce a new test example.
  • Please check Allow edits by maintainers to make review process faster. Note that this option is not available for repositories that are owned by Github organizations.

Tests

  • Run the tests with pnpm test:ci.

Documentation

  • If you introduce new functionality, document it. You can run documentation with pnpm run docs command.

Changesets

  • Changes in changelog are generated from PR name. Please, make sure that it explains your changes in an understandable manner. Please, prefix changeset messages with feat:, fix:, perf:, docs:, or chore:.

Resolves #286 

Vitest 4.1.0 changed suite hook signatures for `beforeAll`/`afterAll`:
the first arg is now fixture context, and the internal suite object
moved to the second arg. That broke `axiom eval`, which uses
`beforeAll(async (suite) => ...)` and failed with `FixtureParseError`.

This PR makes eval hooks work on both Vitest 4.0.x and 4.1.x by
normalizing the hook arguments in one small compatibility wrapper, while
keeping the actual hook logic in explicit `handleBeforeAll` /
`handleAfterAll` functions. It also makes the afterAll task status
checks safer with `task.meta.case?.status`.

Context:

Vitest release: https://github.com/vitest-dev/vitest/releases/tag/v4.1.0

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Moderate risk because it changes how `beforeAll`/`afterAll` hooks
receive the Vitest suite object, which can affect evaluation
initialization/finalization and reporting if the compatibility shim is
wrong.
> 
> **Overview**
> Fixes `axiom eval` running under Vitest 4.1 by adding a small
compatibility wrapper (`withCompatibleSuiteHook`) that normalizes
`beforeAll`/`afterAll` hook arguments across Vitest versions and
refactors the hook bodies into `handleBeforeAll`/`handleAfterAll`.
> 
> Also hardens end-of-suite case counting by treating `task.meta.case`
as optional (`case?.status`) to avoid crashes when case metadata is
missing.
