+
+## Context
+
+ADR 0329 already names leftover-map comparison leftover-axis ticks
+`leftover map comparison leftover axis {axis} tick {value}`. ADR 0329 already names leftover-map
+singular values `σ_k` on those ticks. ADR 0333 already names leftover-map
+axis share on those ticks. Rank-0 unused axes still persist leftover-map
+origin `0.00` (`formatSignedLeftoverValue(0)` emits no plus). Origin ticks
+still interpolate leftover-map origin only through leftover-map comparison leftover-axis tick keys.
+Share and singular omit independently. A finite negative leftover is shown,
+never clamped. Do not invent leftover-map origin from leftover-map axis share
+or leftover-map singular values `σ_k`. leftoverMapPlotTickAxisBadge stays leftover-map graphic leftover-map
+axis origin tick keys from ADR 0343. leftoverMapComparePlotTickAxisBadge stays leftover-map comparison graphic leftover-map
+axis origin tick keys from ADR 0344. leftoverMapAxisTickBadge stays leftover-map tick keys
+this increment.
+
+This increment names leftover-map comparison leftover-axis origin ticks as
+leftoverMapCompareAxisTickBadge. Leftover-map comparison leftover-axis origin ticks stay
+`leftover map comparison leftover axis {axis} origin tick {value}`
+when leftoverMapPlotTickIsOrigin returns true, so they stay distinct from leftover-map
+comparison leftover-axis ticks
+`leftover map comparison leftover axis {axis} tick {value}`,
+leftover-map comparison graphic leftover-map axis origin ticks
+`leftover map comparison graphic leftover-map axis {axis} origin tick {value}`,
+and leftover-map graphic leftover-map axis origin ticks
+`leftover-map axis {axis} origin tick {value}`.
+Share and singular still omit independently:
+`leftover map comparison leftover axis {axis} origin tick {value} σ {singular}`,
+`leftover map comparison leftover axis {axis} origin tick {value} {share}%`, and
+`leftover map comparison leftover axis {axis} origin tick {value} σ {singular} {share}%`.
+It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0345** so it does not collide with leftover-map
+comparison graphic leftover-map axis origin ticks independently of leftover-map axis share and leftover-map singular values
+(0344) or leftover-map comparison leftover-axis origin ticks (#877).
+
+## Decision
+
+On leftover-map comparison leftover-axis ticks, caption leftover-map origin
+when leftoverMapPlotTickIsOrigin returns true. Rank-0 unused axes still name leftover-map
+origin `0.00`. Share and singular omit independently of leftover-map origin.
+Non-origin ticks stay leftover-map comparison leftover-axis tick keys. leftoverMapPlotTickAxisBadge,
+leftoverMapComparePlotTickAxisBadge, 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-axis origin ticks name
+leftover-map origin independently of leftover-map axis share and leftover-map
+singular values. Rank-0 unused axes still name leftover-map origin `0.00`.
+leftoverMapPlotTickAxisBadge stays leftover-map graphic leftover-map axis origin tick keys.
