+    title: New RFID filaments need the Spoolman filament Weight field set
+    decision: RFID spool app creates new Spoolman filaments with a blank Weight. For each NEW
+      material, set Filaments > Weight in Spoolman (e.g. 1000 g). A blank filament Weight
+      freezes that spool's main sensor; the spool's own weight is not enough.
+    rationale: "v1.4.0 bug: Spool._handle_coordinator_update() early-returns before
+      async_write_ha_state() when filament['weight'] is None, so the main spool sensor
+      never pushes state and used_percentage is absent; sub-sensors still update so only
+      the tile looks stale. Fix is data (set the filament Weight), which survives HACS
+      updates and needs no restart; a local code patch does not persist because HACS
+      replaces the file on update."
