In run 38702315040 the app started under Xvfb and showed onboarding, but tesseract's single global threshold, pulled down by the black screen outside the window and the illustration, lost the grey text and the white labels on the blue buttons, so "Create your profile" was never found. A local adaptive threshold (-lat) on the enlarged grayscale image and on its negative turns both into dark text on white. Each shot now also keeps the two images OCR read, in UI_OUT/ocr.
The branch's Kotlin does not compile yet (DirectorySearch.kt and DirectorySearchView.kt import chat.simplex.res.MR instead of chat.simplex.res.*), so the app job stops before the UI steps. A new release job downloads the desktop .deb of the branch's latest release tag for the runner's Ubuntu and runs the same smoke test on it, which exercises Xvfb, openbox, xdotool and the OCR helper independently of the branch build. The smoke test now checks that the typed text appears in the search field and reports whether the Search in Directory row is shown, since releases before directory search don't have it. This run also checks that the core library cache is hit.
First iteration on f/ci-desktop: the core job builds libsimplex.so with scripts/desktop/build-lib-linux.sh on ubuntu-24.04 (GHC 9.6.3, direct-sqlcipher +openssl, no VLC) and caches it by source hash, with the cabal store cached separately. The app job builds :desktop:createDistributable with Corretto 17 and the repo's assets, runs :common:desktopTest, then starts the app under Xvfb and openbox with software rendering and drives onboarding to the chat list and typing in the search field with the ui helper (xdotool input, tesseract OCR to find text), saving numbered screenshots, the text read from them and a step log as artifacts.
