Danijel Martinek 1108e24ea0 chore(deps): backfill library traces for un-cited cluster

Add approved trace files for payload, @trpc/server, @trpc/client, zod,
superjson, @payloadcms/db-postgres, @payloadcms/richtext-lexical, globals,
react, react-dom, vitest, @tanstack/react-query, and all @testing-library/*
packages. All traces dated 2026-05-14, decision: approved, adr: null.

Establishes the baseline so the pre-commit library-decisions gate is
additive (new deps require traces) rather than disruptive (old deps fail
immediately). All 34 trace files pass validateTrace() from schema.mjs.

npm view vitest license

npm view vitest version

pnpm audit --audit-level=moderate

Filter: license

npm view vitest license returns MIT. MIT is on the allowlist.

Filter: types

vitest is authored in TypeScript and ships its own .d.ts declaration files. No separate @types/vitest package is needed.

Filter: maintenance

Actively maintained by the Vite / Vitest team. The 3.x line is the current major. Regular releases with strong community momentum in the Vite ecosystem.

Filter: boundary-fit

vitest is listed as a runtime dependency of @repo/core-testing because it provides the test runner APIs (describe, it, expect, vi) that core-testing re-exports or uses in its test utilities. All feature packages declare vitest as a devDependency. This is the correct placement for a testing infrastructure package.

Filter: shadow-check

vitest is the sole test runner in the workspace. No competing runner (Jest, Jasmine, Mocha) is present.

Filter: eu-residency

vitest is a local test runner with no network communication to vendor-controlled endpoints. EU residency does not apply.

Filter: cve-scan

pnpm audit --audit-level=moderate reports no advisories against vitest at the time of this trace.

Filter: named-consumer

@repo/core-testing lists vitest as a runtime dependency. Every feature package uses vitest as a devDependency for running tests. Named, non-hypothetical consumers exist today.

Prompt: replaces

vitest replaces Jest as the test runner. The Vite-based transformation pipeline eliminates the need for Babel transforms and provides native ES module support, reducing test suite configuration complexity.

Prompt: migration-cost-out

Hard. vitest's describe / it / expect / vi.fn() APIs are used in every test file across all packages. Migrating to Jest or another runner requires updating all test files (largely mechanical API renames) and reconfiguring the coverage pipeline (ADR-020 L0 thresholds, @vitest/coverage-v8).

Prompt: alternatives-considered

Jest — Mature but requires additional Babel/ESM configuration in a Vite-based monorepo; vitest provides native compatibility.
Node.js node:test — Lightweight but lacks the ecosystem integrations (coverage, snapshot, mocking) that vitest provides out of the box.
