- Persist ACARS/VDL2 messages across page refresh via new /acars/messages and /vdl2/messages endpoints backed by FlightCorrelator - Add clear buttons to ACARS/VDL2 sidebars and right-panel datalink section with /acars/clear and /vdl2/clear endpoints - Fix right-panel DATALINK MESSAGES flickering by diffing innerHTML before updating, with opacity transition for smooth refreshes - Add aircraft deselect toggle (click selected aircraft again to deselect) - Enrich VDL2 messages with ACARS label translation (label_description, message_type, parsed fields) matching existing ACARS translator Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
