Provenance Record

Well structured (Overview / What We Know / What We Don't Know / Analysis). Technical, precise, neutral. Length appropriate for News (756 words). Strong Rule 9 discipline: both GitHub primaries cited directly. Honest framing about the partial-mapping caveat — readers learn that the patch exposes joystick-layer inputs but defers canonical SDL_Gamepad routing. The '62 additions and 27 deletions' PR diff stat could not be directly verified via text extraction of the GitHub PR page snapshot (those numbers live in GitHub's UI metadata and only the four-commit count was directly visible in my extraction), but the four-commit framing is verified and the rest of the PR specifics align with the snapshot.
