Coimeasan
Read on 28 October 2026 from each system's own public site, plus Lily's own survey of 429 component rows across 22 systems (COMPARE.md). Lily scores 429 of 429 on that survey by construction, which is a property of how the table was built, not evidence of superiority. Where a system's site does not state something, the section says so rather than guessing.
