The resvg suite's manual vdiff results (1679 tests; 1 pass, 2 fail, 3 crash, 0 undefined) recount exactly to the producer's figures: resvg passes most (1522), then Chrome 1425, Firefox 1387, Safari 1343, librsvg 1171, Inkscape 987, Batik 978 (200 crashes), qtsvg 593 and svgnet 530 (424 undefined); resvg and Chrome disagree mostly in filters, text and painting. The record has no renderer versions, is maintained by resvg's author, and the site counts undefined as passed.

Curator qualifications: Code, docs and CSV read 2026-10-22; no raw file decoded, no SVG rendered. Results last touched 2024-08-20 per producer commit listing (not re-checked); renderer versions unrecorded; author-maintained suite (possible home-team bias).

Limitations: Code, docs and CSV read 2026-10-22; no raw file decoded, no SVG rendered.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
