App 0.2.39 / firmware 0.2.33, items 1, 2, 4, 5 and 6 of the 30-screen scaling check. - Only the tiles (and top bar) of changed entities are rebuilt; the screen list is cached until the registry or a screen diagnostic changes; the SSE stream follows. - Sensor history comes from one recorder/statistics_during_period call per window in a background task, with the REST history as fallback per sensor without statistics. - Firmware 0.2.33 answers a keepalive ping with its layout revision; a mismatch or a restart asks for the layout again, everything is repeated hourly as a safety net. - The screen_message API action takes one whole message; the text inbox chunks stay as fallback for older firmware. A repeated unchanged layout keeps the inbox state. - Quiet diagnostics: Opgestart (uptime as timestamp) replaces Uptime, heap every 5 min, setting numbers publish only on change.
