+
+## Context
+
+ADR 0320 already ticks leftover-map comparison graphic leftover-map axes at the origin
+and at each unique finite persisted `ξ` / `ζ` projection. The origin is the rank-0
+unused-axis location, not a leftover score. ADR 0331 already captions leftover-map
+comparison graphic leftover-map axis ticks with leftover-map axis share through leftoverMapComparePlotTickAxisBadge
+independently of leftover-map singular values. Those leftover-map comparison graphic leftover-map
+axis origin ticks still reuse leftover-map comparison graphic leftover-map axis tick copy
+`leftover map comparison graphic leftover-map axis {k} tick {value}`, so a buyer who reads leftover-map
+comparison graphic leftover-map axis ticks can treat leftover-map origin `0.00` as leftover-map
+coordinate structure without a next action. A missing or non-finite leftover-map axis share is
+not a leftover score and must omit independently of leftover-map singular values. Rank-0 unused
+axes still persist leftover-map origin at `0`. A finite negative leftover is shown, never
+clamped. Do not invent leftover-map origin from leftover-map axis share or `σ_k`. Do not invent leftover-map
+axis share from `σ_k`. Do not invent `σ_k` from leftover-map axis share. Leftover-map graphic leftover-map
+axis ticks never name leftover-map origin this increment. Leftover-map comparison leftover-axis
+ticks and leftover-axis ticks never name leftover-map origin this increment.
+
+This increment names leftover-map comparison graphic leftover-map axis origin ticks as leftoverMapComparePlotTickAxisBadge,
+matching leftoverMapComparePlotTickAxisBadge leftover-map axis share and leftover-map singular values.
+Leftover-map comparison graphic leftover-map axis origin ticks stay
+`leftover map comparison graphic leftover-map axis {k} origin tick {value}` when leftover-map axis share
+and `σ_k` omit,
+`leftover map comparison graphic leftover-map axis {k} origin tick {value} {share}%` when leftover-map
+axis share is finite and `σ_k` omits,
+`leftover map comparison graphic leftover-map axis {k} origin tick {value} σ {singular}` when `σ_k` is
+finite and leftover-map axis share omits, and
+`leftover map comparison graphic leftover-map axis {k} origin tick {value} σ {singular} {share}%`
+when both are finite, so they stay distinct from leftover-map comparison graphic leftover-map axis ticks
+`leftover map comparison graphic leftover-map axis {k} tick {value} σ {singular} {share}%` (ADR 0331),
+from leftover-map graphic leftover-map axis ticks
+`leftover-map axis {k} tick {value} σ {singular} {share}%` (ADR 0332),
+from leftover-map comparison leftover-axis ticks
+`leftover map comparison leftover axis {k} tick {value} σ {singular} {share}%` (ADR 0333),

+and from leftover-map comparison graphic leftover-map axis
+`leftover map comparison graphic leftover-map axis {k} σ {value} ({share}%)` (ADR 0326).
+It does not add columns. Do not invent a leftover score. Do not invent a theta.

+
+## Decision
+
+On leftover-map comparison graphic leftover-map axis origin ticks, caption leftover-map axis `k`
+origin `0.00` when leftoverMapComparePlotTickAxisBadge returns a usable leftover-map origin tick
+caption. Share and singular value omit independently through that helper: no `σ_k` and no
+share keeps `leftover map comparison graphic leftover-map axis {k} origin tick {value}`;
+`σ_k` only is `leftover map comparison graphic leftover-map axis {k} origin tick {value} σ {singular}`;
+share only is `leftover map comparison graphic leftover-map axis {k} origin tick {value} {share}%`;
+both are `leftover map comparison graphic leftover-map axis {k} origin tick {value} σ {singular} {share}%`.
+A missing or non-finite leftover-map axis share omits that share origin tick caption and
+keeps a usable leftover-map comparison graphic leftover-map axis origin tick coordinate caption,
+including any leftover-map singular value. Rank-0 unused axes still name leftover-map origin
+`0.00` and leftover-map axis share `0%`. Click a post marker to open that post. Criterion markers are not post
+buttons.
+
+Leftover-map comparison graphic leftover-map axis origin ticks omit independently of leftover-map
+graphic leftover-map axis ticks, leftover-map comparison leftover-axis ticks, leftover-axis ticks, leftover-map
+comparison graphic leftover-map axis leftover-map axis share, and leftover-map comparison graphic leftover-map
+axis leftover-map singular values. A missing leftover-map singular value omits leftover-map singular
+values and keeps a usable leftover-map comparison graphic leftover-map axis origin tick leftover-map
+axis share caption. Do not invent leftover-map origin from leftover-map axis share or leftover-map singular
+values. Coordinate ticks that are not leftover-map origin keep leftover-map comparison graphic leftover-map
+axis tick copy.
+
+This increment does not change leftover-map graphic leftover-map axis ticks, leftover-map comparison leftover-axis
+ticks, or leftover-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 axis origin ticks name leftover-map
+origin when leftoverMapComparePlotTickAxisBadge returns a usable leftover-map comparison graphic leftover-map
+axis origin tick caption even when leftover-map axis share or leftover-map singular
+values are omitted; click a leftover pair opens that post. Hidden posts stay hidden. Rank-0 unused
