+
+## Context
+
+ADR 0267 already persists two-axis Gabriel person coordinates
+`ξ_{1:2}` and item coordinates `ζ_{1:2}` on leftover pair rows so
+`R̂ = ξ_{1:2} · ζ_{1:2}` and `d = ‖ξ_{1:2} − ζ_{1:2}‖` stay
+auditable. ADR 0268 already draws leftover-map graphic leftover-map
+post markers at persisted `ξ` and leftover-map graphic leftover-map
+criterion markers at persisted `ζ`. ADR 0304 reuses that graphic on the grouping
+comparison strip. ADR 0335 already names leftover-map graphic leftover-map
+criterion markers `leftover-map criterion {label} at ζ {item}` independently of leftover-map
+post `ξ` markers. ADR 0336 already names leftover-map comparison graphic leftover-map
+criterion markers `leftover map comparison graphic leftover-map criterion {label} at ζ {item}`
+independently of leftover-map post `ξ` markers. Those leftover-map comparison graphic leftover-map
+post markers still read `Open leftover-map post {title} at ξ {person}`, so a buyer who
+reads leftover-map comparison graphic leftover-map post markers can treat leftover-map location as leftover-map graphic leftover-map
+post `ξ` without a next action on leftover-map comparison graphic leftover-map post leftover-map person coordinates. A missing or
+non-finite leftover-map person coordinate pair is not a leftover score and
+must omit independently of leftover-map criterion leftover-map item coordinates. Rank-0 unused
+axes still persist leftover-map person coordinates `(0.00, 0.00)`. A finite
+negative leftover is shown, never clamped. Do not invent leftover-map
+person coordinates from leftover-map item coordinates `ζ`. Do not invent leftover-map
+item coordinates `ζ` from leftover-map person coordinates `ξ`. Leftover-map graphic leftover-map
+post markers stay `Open leftover-map post {title} at ξ {person}` this increment.
+
+This increment names leftover-map comparison graphic leftover-map post markers leftover-map
+person coordinates as leftoverMapComparePlotPostBadge, matching leftover-map
+comparison graphic leftover-map criterion leftover-map item coordinates. Leftover-map comparison graphic leftover-map
+post markers stay
+`Open leftover map comparison graphic leftover-map post {title} at ξ {person}`
+when leftover-map person coordinates are finite, so they stay distinct from leftover-map
+graphic leftover-map post markers `Open leftover-map post {title} at ξ {person}` and from leftover-map
+comparison graphic leftover-map criterion markers `leftover map comparison graphic leftover-map criterion {label} at ζ {item}`.
+It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0337** so it does not collide with leftover-map
+comparison graphic leftover-map criterion leftover-map item coordinates independently of leftover-map post ξ markers
+(0336), leftover-map graphic leftover-map criterion leftover-map item coordinates independently of leftover-map post ξ markers

+(0331), leftover-map graphic display on the grouping comparison strip (0304), leftover-map graphic display (0268), leftover-map coordinates (0267),
+or the dashboard stacks.
+
+## Decision
+
+On leftover-map comparison graphic leftover-map post markers, caption leftover-map
+person coordinates `ξ_{1:2}` when leftoverMapComparePlotPostBadge
+returns a usable leftover-map comparison graphic leftover-map post leftover-map person coordinate caption.
+A missing or non-finite leftover-map person coordinate pair omits that leftover-map
+comparison graphic leftover-map post leftover-map person coordinate caption and keeps
+`Open leftover-map post {title}`. Rank-0 unused axes still name leftover-map
+person coordinates `(0.00, 0.00)`. Click a leftover pair or a leftover-map
+post marker to open that post. Criterion markers are not post buttons.
+
+Leftover-map comparison graphic leftover-map post leftover-map person coordinates omit
+independently of leftover-map criterion leftover-map item coordinates. This increment does not
+change leftover-map graphic leftover-map post markers,
+leftover-map graphic leftover-map criterion markers,
+leftover-axis ticks, leftover-map graphic leftover-map axis ticks, leftover-map
+comparison leftover-axis ticks, or leftover-map comparison graphic leftover-map
+axis ticks. This increment does not persist leftover-map inner product, cosine, or length.
+
+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 graphic leftover-map post markers name persisted
+leftover-map person coordinates when leftoverMapComparePlotPostBadge returns a usable
+leftover-map comparison graphic leftover-map post leftover-map person coordinate caption; click a leftover pair
+or a leftover-map post marker opens that post. Hidden posts stay hidden. Rank-0 unused
+axes still name leftover-map comparison graphic leftover-map post leftover-map person coordinates
+`(0.00, 0.00)`. Leftover-map graphic leftover-map post markers stay
+`Open leftover-map post {title} at ξ {person}`. Leftover-map comparison graphic leftover-map criterion leftover-map item coordinates independently of leftover-map
