+
+## Context
+
+ADR 0338 already names leftover-map graphic leftover-map post leftover-map person coordinates
+`Open leftover-map post {title} at ξ {person}`. Rank-0 unused axes still persist leftover-map
+origin `(0.00, 0.00)` (`formatSignedLeftoverValue(0)` emits no plus). Origin leftover-map
+person coordinates still interpolate leftover-map origin only through leftover-map post leftover-map
+person coordinate keys. A missing or non-finite leftover-map person coordinate pair omits independently
+of leftover-map item coordinates `ζ`. A finite negative leftover is shown, never clamped.
+Do not invent leftover-map origin from leftover-map item coordinates `ζ`. leftoverMapComparePlotPostBadge stays
+`Open leftover map comparison graphic leftover-map post {title} at ξ {person}`
+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 graphic leftover-map post leftover-map origin leftover-map
+person coordinates as leftoverMapPlotPostBadge. Leftover-map graphic leftover-map post leftover-map origin leftover-map
+person coordinates stay
+`Open leftover-map post {title} at leftover-map origin ξ {person}`
+when leftoverMapPlotCoordinatePairIsOrigin returns true, so they stay distinct from leftover-map
+graphic leftover-map post leftover-map person coordinates
+`Open leftover-map post {title} at ξ {person}`,
+leftover-map comparison graphic leftover-map post leftover-map person coordinates
+`Open leftover map comparison graphic leftover-map post {title} at ξ {person}`,
+and leftover-map graphic leftover-map criterion leftover-map origin leftover-map item coordinates
+`leftover-map criterion {label} at leftover-map origin ζ {item}`.
+It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0348** so it does not collide with leftover-map graphic leftover-map
+criterion leftover-map origin leftover-map item coordinates independently of leftover-map person coordinates
+(0347) or leftover-map leftover-axis origin ticks (#877).
+
+## Decision
+
+On leftover-map graphic leftover-map post markers, 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 person coordinates stay leftover-map post leftover-map
+person coordinate keys. leftoverMapComparePlotPostBadge, leftoverMapPlotCriterionBadge,
+leftoverMapListPostBadge, leftoverMapCompareListPostBadge, 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 graphic leftover-map post leftover-map origin leftover-map person
