+## Context
+
+ADR 0148 already persists leftover-map singular values `σ_k` and leftover-map
+axis share `σ_k² / Σ_j σ_j²`. ADR 0270 already ticks leftover-map graphic leftover-map
+axes at persisted `ξ` / `ζ` projections as `leftover-map axis {k} tick {value}`.
+ADR 0324 already captions leftover-map graphic-display leftover-map axes with
+`σ_k`. Those leftover-map graphic leftover-map axis ticks still omit `σ_k`, so a
+buyer who reads leftover-map graphic leftover-map axis ticks can treat leftover-map
+coordinate ticks or leftover-map axis share as leftover-map structure without a
+next action. A missing, non-finite, or negative singular value is not a leftover
+score and must omit independently of leftover-map axis share. Rank-0 unused axes
+still persist `σ_k = 0`. A finite negative leftover is shown, never clamped. Do
+not invent `σ_k` from leftover-map axis share. Do not invent leftover-map axis
+share from `σ_k`. Leftover-map graphic leftover-map axis ticks never name leftover-map
+axis share.
+
+This increment names leftover-map graphic leftover-map axis ticks leftover-map
+singular values as leftoverMapPlotTickAxisBadge, matching leftoverMapComparePlotAxisBadge,
+leftoverMapPlotAxisBadge, leftoverMapCompareAxisBadge, and leftoverMapAxisBadge.
+Leftover-map graphic leftover-map axis ticks stay
+`leftover-map axis {k} tick {value} σ {singular}` when `σ_k` is finite so they stay
+distinct from leftover-map graphic leftover-map axis `leftover-map axis {k} σ {value}`
+(ADR 0324), from leftover-axis `leftover axis {k} σ {value}` (ADR 0325), from
+comparison leftover-axis `leftover map comparison leftover axis {k} σ {value}`
+(ADR 0323), from comparison graphic leftover-map axis
+`leftover map comparison graphic leftover-map axis {k} σ {value}` (ADR 0326), and
+from comparison graphic leftover-map axis ticks
+`leftover map comparison graphic leftover-map axis {k} tick {value}` (ADR 0320).
+It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0327** so it does not collide with leftover-map
+comparison graphic leftover-map axis leftover-map singular values as leftoverMapComparePlotAxisBadge
+(0326), leftover-map singular values on leftover-axis report badges independently of
+leftover-map axis share (0325), leftover-map singular values on leftover-map graphic-display
+axes (0324), leftover-map coordinate ticks on the grouping comparison leftover-map graphic
+(0320), leftover-map axis share persistence (0148), or the dashboard stacks.
+
+## Decision
+
+On leftover-map graphic leftover-map axis ticks, caption leftover-map axis `k`
+with persisted leftover-map singular value `σ_k` when leftoverMapPlotTickAxisBadge
+returns a usable leftover-map axis tick caption that includes that singular value.
+Share and singular value omit independently through that helper, and leftover-map
+axis share is never named on leftover-map graphic leftover-map axis ticks: no `σ_k`
+keeps `leftover-map axis {k} tick {value}`; `σ_k` only is
+`leftover-map axis {k} tick {value} σ {singular}`. A missing, non-finite, or
+negative singular value omits that `σ` tick caption and keeps a usable leftover-map
+graphic leftover-map axis tick coordinate caption. Rank-0 unused axes still name
+`σ 0.00`. Click a post marker to open that post. Criterion markers are not post
+buttons.
+
+Leftover-map graphic leftover-map axis tick leftover-map singular values omit
+independently of leftover-map graphic-display leftover-map axis singular values,
+leftover-axis report badge leftover-map singular values, leftover-map comparison
+leftover-axis singular values, leftover-map comparison graphic leftover-map axis
+singular values, and leftover-map comparison graphic leftover-map axis ticks. A
+missing leftover-map axis share omits leftover-map axis share and keeps a usable
+leftover-map graphic leftover-map axis tick `σ` caption.
+
+This increment does not change leftover-map comparison graphic leftover-map axis
+ticks. Those comparison graphic leftover-map axis ticks stay
+`leftover map comparison graphic leftover-map axis {axis} tick {value}` (ADR 0320).
+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 graphic leftover-map axis ticks name persisted
+leftover-map singular values when leftoverMapPlotTickAxisBadge returns a usable
+leftover-map axis tick `σ` caption even when leftover-map axis share is omitted;
