+## Context
+
+ADR 0342 already names leftover-map comparison leftover-pair leftover-map criterion leftover-map item coordinates
+`leftover map comparison leftover pair leftover-map criterion {label} at ζ {item}`. Rank-0 unused axes still persist leftover-map
+origin `(0.00, 0.00)` (`formatSignedLeftoverValue(0)` emits no plus). Origin leftover-map
+item coordinates still interpolate leftover-map origin only through leftover-map comparison leftover-pair leftover-map criterion leftover-map
+item coordinate keys. A missing or non-finite leftover-map item coordinate pair omits independently
+of leftover-map person coordinates `ξ`. A finite negative leftover is shown, never clamped.
+Do not invent leftover-map origin from leftover-map person coordinates `ξ`. leftoverMapCompareListPostBadge stays
+`leftover map comparison leftover pair leftover-map post {title} at leftover-map origin ξ {person}`
+this increment. leftoverMapListCriterionBadge stays
+`leftover pair leftover-map criterion {label} at leftover-map origin ζ {item}`
+this increment. leftoverMapComparePlotCriterionBadge stays
+`leftover map comparison graphic leftover-map criterion {label} at leftover-map origin ζ {item}`
+this increment. leftoverMapPlotCriterionBadge stays leftover-map graphic leftover-map
+criterion leftover-map origin leftover-map item coordinate keys this increment.
+
+This increment names leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map
+item coordinates as leftoverMapCompareListCriterionBadge. Leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map
+item coordinates stay
+`leftover map comparison leftover pair leftover-map criterion {label} at leftover-map origin ζ {item}`
+when leftoverMapPlotCoordinatePairIsOrigin returns true, so they stay distinct from leftover-map
+comparison leftover-pair leftover-map criterion leftover-map item coordinates
+`leftover map comparison leftover pair leftover-map criterion {label} at ζ {item}`,
+leftover-map pair leftover-map criterion leftover-map origin leftover-map item coordinates

+and leftover-map comparison leftover-pair leftover-map post leftover-map origin leftover-map person coordinates
+`leftover map comparison leftover pair leftover-map post {title} at leftover-map origin ξ {person}`.
+It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0354** so it does not collide with leftover-map comparison leftover-pair leftover-map

+
+## Decision
+
+On leftover-map comparison leftover-pair leftover-map criterion, caption leftover-map origin
+when leftoverMapPlotCoordinatePairIsOrigin returns true. Rank-0 unused axes still name leftover-map
+origin `(0.00, 0.00)`. Non-origin leftover-map item coordinates stay leftover-map comparison leftover-pair leftover-map criterion leftover-map

+leftoverMapPlotTickAxisBadge, leftoverMapComparePlotTickAxisBadge, leftoverMapCompareAxisTickBadge, and leftoverMapAxisTickBadge
+do not change leftover-map origin naming this increment.
+
+Do not add SQL. Do not edit shipped migrations. Do not invent a leftover
+score. Do not invent a theta.
+
+## Consequences
+
+After `make seed`, leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map item
+coordinates name leftover-map origin independently of leftover-map comparison leftover-pair leftover-map post leftover-map origin leftover-map person coordinates. Rank-0 unused
