Every comment is reduced to its first sentence plus @param, @return and @throws tags. Comment lines: 20040 to 8526. ktlint 1.8 applied with its default (official Kotlin) style across all modules; 262 files reformatted. The 264 remaining ktlint findings are naming and filename rules, which are code changes, and are left alone. Comments and formatting only. 1208 tests pass, counted from the XML.
