+tests/scripts/linux-installed.sh:61 — L1.6 lacks the required Ubuntu/Fedora runtime smoke tests. `installed` runs the live Arch host’s binaries; `linux-packages.sh` only checks installation and linkage. In a copied ElyTree deb, replacing the main ELF with Ubuntu’s `/bin/false` makes startup exit 1 without a window, yet the package test still exits 0. Run the deb/rpm applications in their respective distro environments and verify successful startup and rendered content. Evidence: `.work/L1.6-r1/package-mutation-build.log` and `package-mutation.log`.

+tests/scripts/linux-mark-idle.sh:84 — The external-edit assertion checks a log emitted before the new content is applied.

Built mutants that skip every document tile still pass both smoke cases with exit 0; Table shows no grid. Use document/cell fixtures with distinct content and assert that engine-rendered content reaches the window. Evidence: `.work/L1.6-r2/no-canvas-evidence.log` and `no-canvas.log`.

Both unmodified `installed` and `appimage` runs exit 1 because Tesseract returns `PaCKaged On Linux`, although the inspected screenshot clearly displays “Packaged on Linux”; an isolated repeat fails identically. Normalize OCR case or use an equally reliable content assertion while preserving OCR error reporting. Evidence: `.work/L1.6-r2/installed.log`, `appimage.log`, and `ocr-evidence.log`.

Wait for the application and its CEF processes to finish before deleting their home. Evidence: `.work/L1.6-r2/mark-idle.log`; the AppImage run also records this cleanup error.

Injecting exit 42 on the first external-edit OCR attempt, then allowing normal OCR, makes the entire idle test exit 0 without reporting the tool error. Capture and check Tesseract's status and diagnostic output separately; retry only successful OCR that lacks the expected text. Evidence: `.work/L1.6-r3/ocr-first-failure.log` and `mark-idle-ocr-failure.log`.

+tests/scripts/linux-common.sh:66 — Cleanup treats every nonzero `pgrep` status as proof that the application session has exited. With a live session that ignores TERM and an injected `pgrep` internal error (exit 3), `stop_app` returns success while the session remains alive; callers can then delete a home still used by the app or CEF, restoring the cleanup race under process-query failure. Treat only exit 1 as no matching processes and propagate other query failures. Evidence: `.work/L1.6-r3/stop-app-failure.log`.
