Implemented Control Center Help System: Fallback Navigation for Child Pages in linuxdeepin/dde-control-center. The change collects the active navigation chain when opening help, applies a NavigationModel-style filter to select only display-name candidates, and passes an ordered list to deepin-manual so child pages without dedicated sections can fall back to parent topics. This improves help coverage, reduces user friction, and aligns help navigation with existing content models. A related fix (PMS: BUG-368805) was committed (4537daeba998ab6f8498a9acae050d8e7d0086c4) and validated end-to-end. Validation included tests for input method add-ons help fallback, verification that shortcuts and network subpages map to the correct manual sections, and packaging checks ensuring no unrelated desktop-file changes in the final debug-machine package.

2026-05 Monthly Summary: Across three core repositories (linuxdeepin/dde-control-center, linuxdeepin/dde-daemon, linuxdeepin/dtkdeclarative), delivered UX refinements, security hardening, and significant performance optimizations. Key outcomes: - dde-control-center: eliminated extraneous taskbar icons when opening the developer mode disclaimer by updating modal window flags; improved keyboard navigation with reliable Tab/Shift+Tab cycling in settings; ensured conflict warning icon refresh after asynchronous shortcut updates. - dde-daemon: reduced launch latency for common shortcuts by migrating to in-process handlers for file manager, terminal, and lock screen actions; added security hardening to prevent shell injection in event log lookups. - dtkdeclarative: removed KWin blur from DialogWindow to improve dark theme compatibility and consistent visuals across themes. These changes improve UX, reliability, and security while reducing user-perceived latency and ensuring consistent theming across applications.

Month: 2026-04 — Focused on reliability and user experience of disk space notifications in linuxdeepin/dde-daemon. Key bug fix implemented to ensure the 'Go to clean up' action only appears when the D-Bus service com.deepin.defender.hmiscreen is available, preventing unresponsive behavior on systems without the service. Introduced D-Bus interop via a new ofdbus package, added isHMIScreenServiceAvailable() using ListActivatableNames, and updated checkSpace() to choose between a notification with an actionable button or a plain warning based on service presence. This decouples behavior from version gating and improves cross-system resilience. The change was delivered with commit b7c74451c5b0d55dfd2793b74acc335ef505ab4e, including tests for both presence and absence of the hmiscreen service. PMS: BUG-355573.
