Provenance Record

Well-structured News piece (510 words, within the 400-1200 range). The headline, summary, and Overview lead all center on the new experimental `deno desktop` command, which is the genuinely new development in 2.9. Clear sectioning (Overview, What deno desktop does, Easier migration, What we don't know) and appropriate technical depth without editorializing.

Both source snapshots read in full from disk and integrity-verified. source-0.html.gz (Deno blog https://deno.com/blog/v2.9, status 200) sha256 dbe68e8c... matches manifest. source-1.html.gz (The Register https://www.theregister.com/.../5261388, status 200) sha256 862f5f8e... matches manifest. Rule 9 attribution confirmed: all technical specifics — June 25 2026 release date, the deno desktop self-contained-binary quote, the framework list (Next.js, Astro, Fresh, Remix, Nuxt, SvelteKit, SolidStart, TanStack Start, Vite SSR), WebView2/WebKit engines, CEF opt-in, 34ms->17ms cold start, Node.js 26 compat, npm/pnpm/yarn/Bun lockfile reading, constructable CSS stylesheets, Deno.test.each, and the 11.6MB->1.5MB bundle drop — all trace verbatim to the Deno blog. The independent 68.5MB-vs-308.9MB macOS binary-size comparison and the macOS WebView close-button bug are cited to The Register alone, with no compound citation. AlternativeTo is not cited anywhere.

Every number, name, date, and quote was matched against the snapshots. All four Deno-blog quotes and all four Register quotes ('the native WebView is used by default...', 'plenty of existing options...', 'looks well thought-out', 'not yet stable') are verbatim. No hallucinations detected.

High-quality, accurately sourced follow-up. Rule 9 attribution boundaries are respected, all quotes verbatim, no orphan URLs, cross-reference resolves. Approved for publication.
