When timeline event is clicked in expert mode, emit jump_to_time command with event timestamp. The time-travel player pauses live playback, seeks CSI recording buffer to timestamp, and begins replay. Selected event highlights in timeline and "Now replaying" chip appears in header. Backend: POST /api/replay/jump-to-time creates replay session centered on timestamp, replaces previous active session. Frontend: handleSeek() in sidebar-timeline delegates to SpaxelReplay.jumpToTime() which calls the API, shows replay control bar, and notifies Viz3D. Tests: 7 Go test cases for jump-to-time endpoint, 8 JS test cases for tap-to-jump interaction, event highlighting, and now-replaying chip. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
