Provenance Record

Well-structured article covering Biome v2's major features including type-aware linting, GritQL plugin system, and domains. Appropriate depth for a News category piece at 896 words.

source-0.html.gz (github.com/biomejs/biome): Confirmed 24.7k stars, 86.3% Rust codebase, MIT/Apache 2.0 licensing. source-1.html.gz (github.com/biomejs/biome/releases): Confirmed v2.4.15 on May 9, 2026. v2.0.0 and v2.4.0 dates not explicitly found in the snapshot but release history structure is consistent. source-2.html.gz (infoq.com/news/2025/06/Biome-Releases-v2-Beta): Confirmed GritQL plugin system, 'plenty of ideas for making them more powerful' quote, 35x faster than Prettier claim, domains concept, Rome lineage. noFloatingPromises as the first type-aware rule is NOT found in this source — it is a specific claim that cannot be verified from available snapshots. source-3.html.gz (infoq.com/news/2026/04/eslint-10-release): Confirmed 120 million weekly npm downloads, Biome/Oxlint as Rust-based alternatives, Oxlint 50-100x faster claim. The 95% figure comes from a Reddit commenter quoted by InfoQ, not InfoQ's own characterization. The article misframes community Reddit comments about ESLint performance as migration friction criticism.

Core claims about Biome v2 features are consistent with sources. Two minor misattributions in a subordinate section: (1) '~95% rule coverage' presented as InfoQ's characterization when it is a Reddit commenter's opinion; (2) Reddit comments characterized as criticizing the 'migration path as poor' when the actual quoted comment was about switching to Biome due to ESLint performance. The InfoQ ESLint article describes migration as 'straightforward'. The noFloatingPromises claim is not verifiable from snapshots but is plausible technical context.

Substantively solid article on a genuine developer tools story. The core claims about Biome v2 features, versioning timeline, and competitive landscape are well-sourced. Two minor misattributions in a subordinate competitive landscape paragraph warrant a corrections record.
