+    title: OctoPrint serial-health sensors removed deliberately
+    decision: sensor.octoprint_serial_health_ratio and
+      binary_sensor.octoprint_serial_health_critical are removed from configuration.yaml
+      and both dashboards. Do not re-add them.
+    rationale: OctoPrint-MQTT never publishes a printer_data.health object, so
+      value_json.printer_data.health.ratio/.critical fell back to float(0)/OFF forever —
+      the tiles always read 0%. No equivalent real data exists (only web-service stats).
+      Removed from printer-stats + ender5-printer dashboards, YAML source deleted,
+      mqtt.reload applied, registry stubs cleaned.
+    entities:
+      - sensor.octoprint_serial_health_ratio
+      - binary_sensor.octoprint_serial_health_critical
+    files:
+      - configuration.yaml
+    integrations:
