All 5 sources fetched successfully. source-0 (vitest.dev blog): confirmed 713+ contributors, tags-filter, viteModuleRunner:false, agent reporter, aroundEach/aroundAll, detect-async-leaks, GitHub Actions reporter, coverage.changed, mockThrow, Vladimir Sheremet/Hiroshi Ogawa/Ari, Chromatic, Vite 8. source-1 (infoq.com): confirmed 'tags allow developers to label tests and apply shared configuration such as timeouts or retries per tag' quote verbatim, '22.18+ or 23.6+' Node.js requirements, agent reporter token reduction, aroundEach/aroundAll 'wrapping tests in contexts such as database transactions or tracing spans' quote. source-2 (voidzero.dev launch week): confirmed 'catch leaked timers that silently break CI' language, agent reporter 'enabled by default when an agent is detected', GitHub Actions reporter Job Summaries. source-3 (github.com/vitest-dev/vitest/releases/v4.1.0): shows 'cpojer, jgillick, and 27 other contributors' — 29 total, NOT 28 as article states. source-4 (voidzero.dev/announcing-vitest-4): the 7M→17M weekly download figure is not found in this snapshot — claim is uncorroborated in available sources. Allowlist warnings: vitest.dev (official Vitest project blog) and voidzero.dev (official VoidZero company blog) are authoritative primary sources.

Two minor issues: (1) article states '28 developers for the v4.1.0 tag' but GitHub releases shows 29 contributors (27 others + 2 named); (2) the 7M→17M weekly download claim attributed to the Vitest 4.0 announcement is not found in the available snapshot of that source — background claim, not a headline fact. All feature descriptions are accurate. APPROVE_WITH_CORRECTIONS for the contributor count.

Well-researched, technically solid developer tools article. Minor contributor count error (28 vs 29) is correctable. APPROVE_WITH_CORRECTIONS.
