+    title: CFS Lite slot matching is by Spoolman spool location, not colour
+    decision: SparkX i7 per-slot filament tracking matches purely on the Spoolman spool's
+      location field == 'CFS Lite <n>' (slots 1-4); the colour check and any fallback were
+      removed. When swapping a roll into a slot, set that spool's Location to 'CFS Lite
+      <n>' — a stale label is the only thing that can misroute a deduction.
+    rationale: "Identical-colour rolls in different slots auto-rotate, so colour alone cannot
+      attribute usage. Only individual spool records were changed; no Spoolman setting or
+      config was touched. Applies to automation 1791477238729 (completion), 1791477238762
+      (latch), 1791477238799 (sufficiency) and script spoolman_set_spool_remaining.
+      Pinned: the manual Location-on-swap step is easy to forget."
