Draw persisted leftover-map coordinates ξ and ζ as a Gabriel biplot above leftover pair buttons (ADR 0268). Click a post marker to open that post. Omit the plot when coordinates are missing. No new columns. Never invent a leftover score or a theta.

* feat(reports): persist leftover-map coordinates (v2.24.0)
Name leftover-map coordinates ξ_{1:2} and ζ_{1:2} on leftover
post–criterion pairs (ADR 0267, migration 0245). After make seed,
closest and farthest leftover pairs sit above the member list with
ξ (x, y) ζ (x, y) next to leftover-map distance d; click opens that
post. Rank-0 unused axes store 0.0. When coordinates, reconstruction,
and distance are finite, R̂ = ξ · ζ and d = ‖ξ − ζ‖. Never invent a
leftover score. Never invent a theta.

* feat(reports): leftover-map axis share on graphic display (v2.26.0) (#787)
Caption leftover-map plot axes with persisted ADR 0148 leftover-map
axis share σ_k² / Σ_j σ_j² (ADR 0269). Rank-0 zero-share axes still
name 0%. A missing or non-finite share omits that axis badge and
keeps the existing leftover-map axis text. Click a post marker to
open that post. No new columns. Never invent a leftover score or a
theta.

* feat(reports): leftover-map coordinate ticks (v2.27.0) (#799)
Caption leftover-map graphic-display axes with persisted leftover-map
coordinate ticks (ADR 0270). After make seed, closest and farthest
leftover pairs sit above the member list with the Gabriel biplot of
already-named coordinates, leftover-map axis share when finite, and
axis ticks that match ξ (x, y) ζ (x, y) on the pair row; click a post
marker or a pair button opens that post. Origin is always named 0.
Rank-0 unused axes do not invent −1 / +1 drawing-scale ticks. Never
invent a leftover score or a theta. No new columns.
* feat(reports): leftover-map distance on pair segments (v2.28.0) (#800)
Caption leftover-map graphic-display pair segments with persisted
leftover-map distance d (ADR 0271). After make seed, closest and
farthest leftover pairs sit above the member list with the Gabriel
biplot of already-named coordinates, leftover-map axis share when
finite, axis ticks that match ξ (x, y) ζ (x, y) on the pair row, and
pair segments that match d on the pair row; click a post marker or a
pair button opens that post. A missing or non-finite d omits that
segment caption. Do not invent d from plotted coordinates. Never
invent a leftover score or a theta. No new columns.

Summary
Leftover-map graphic display of already-persisted leftover-map coordinates (ADR 0268 / v2.25.0).
Gabriel (1971) is a graphic display of the same two marker sets ADR 0267 already names. After
make seed, closest and farthest leftover pairs sit above the member list with the biplot of persisted coordinates; click a post marker or a pair button opens that post.feat/leftover-map-coordinates-v2240).
