Provenance Record

Well-structured, appropriate depth for a conference roundup. Covers VS Code extension alpha, Kotlin 2.4-RC stabilizations, productivity study, and ecosystem announcements. The 'What We Don't Know' section is a good editorial addition.

All 5 sources verified from disk snapshots. source-0 (JetBrains keynote blog): confirmed KMP adoption doubling, 17% KSP, 50% R8, 25% Kotlin/Native build, 86.4% SWE-bench, 92% Android devs, 3500+ klibs, context parameters/explicit backing fields stabilization, 18-month security policy, Swift Export Alpha. source-1 (VS Code extension blog): confirmed feature list (code completion, diagnostics, navigation, quick-fixes, formatting, project import), extension name, LSP foundation, 'part of our ongoing work' quote. source-2 (GitHub kotlin-lsp): confirmed partially closed-source note, LSP compatibility with any editor, extension ID JetBrains.kotlin-server. source-3 (productivity study): confirmed 320,000 developers, 28 million cycles, 20-month window, 15.7%/20.3%/15.1% breakdown, Java slowdown 9–17%. source-4 (InfoWorld): confirmed Alina Dolgikh quote verbatim, February 19 introduction date. Two issues found: (1) R8 50% saving misattributed to Kotlin/Native; (2) 'doubled over past year' paraphrase in quote marks where source says 'more than doubling'.

Most claims are accurate and well-sourced. Two specific issues: the R8/50% benchmark is an Android optimization attributed incorrectly to Kotlin/Native; the 'doubled' KMP quote drops 'more than' from the source, weakening the actual statistic while presenting it as verbatim.

Solid conference roundup with accurate headline and lead claims. Two recoverable body issues documented above — both can be honestly covered by corrections notes.
