Added

• About tab in Settings with a randomly rotating short text block, the project manifesto, donation links (GitHub Sponsors, Buy Me a Coffee, Ko-fi, Liberapay), star repo, and create issue shortcuts.
• Inspector summary now shows the resource creation timestamp alongside age in local time.
• Three-state column pin (auto, pinned, hidden) replaces the global auto-hide setting and is exposed through the column header context menu with a lock icon for pinned columns.
• Local time zone formatting for human timestamps with offset fallback for unknown zones.
• .github/FUNDING.yml, CODE_OF_CONDUCT.md, pull request template, and shared package metadata (Directory.Build.props).
• Rule-based alert editor with locked default rules, custom matcher groups, color/animation/zoom actions, and alert-specific sound selection.
• Bundled audio catalog with searchable CC0/OSS sound choices, attribution, source links, mute control, and priority queued alert playback.
• Release automation for cross-platform desktop archives.

Changed

• Window-lifetime event handlers (ViewModel.PropertyChanged, pulse strip routed events, YAML/log editor pointer events, source row PropertyChanged) are now unsubscribed on window close.
• Pulse layer aggregation rewritten as a single pass over the row collection.
• Audit sweep: DataGrid parity (named grids, EventGrid sort, FocusedEvents SortMemberPath, relationships Link label), localized tooltips and menu actions, removed undefined brush keys.
• 33 trivial click handlers collapse to expression bodies and single-line dispatches.
• Release automation now starts from main, tests first, packages every supported runtime, then creates the date tag and GitHub release.
• Release assets now include SHA256 checksums.
• Release assets now cover Linux glibc, Linux musl, Windows, and macOS across supported x64, x86, arm, and arm64 runtimes.
• Built-in activity/problem radar behavior is represented by default alert rules so users can enable, disable, duplicate, and extend the same mechanics.
• k3d integration test bootstrap now installs pinned k3d and kubectl versions when missing.
• Public repository documentation and release packaging were cleaned up for open-source use.
