Subject: [PATCH] feat(reports): leftover-map singular values on leftover-axis
report badges independently of leftover-map axis share (v2.82.0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Caption leftover-axis report badges with persisted leftover-map singular
values σ_k independently of leftover-map axis share (ADR 0325). Period
leftover-axis copy stays leftover axis {k} σ {value} when share is omitted
so it stays distinct from leftover-axis leftover axis {k} σ {value} {share}%,
from hyphen leftover-map axis {k} σ {value}, from comparison leftover-axis
leftover map comparison leftover axis {k} σ {value}, and from comparison
graphic leftover map comparison graphic leftover-map axis {k} σ {value}.
Rank-0 unused axes still name σ 0.00. Share and singular value omit
independently. Do not invent σ_k from leftover-map axis share. Do not invent
leftover-map axis share from σ_k. Never invent a leftover score. Never invent
a theta.

+
+## Context
+
+ADR 0148 already persists leftover-map singular values `σ_k` and leftover-map
+axis share `σ_k² / Σ_j σ_j²`. ADR 0322 captions leftover-axis report badges
+with `leftover axis {axis} σ {value} {share}%` when `σ_k` is finite, and
+falls back to `leftover axis {axis} {share}%` when `σ_k` is omitted. Those
+badges still couple leftover-map singular values to leftover-map axis share:
+a missing, non-finite leftover-map axis share is formatted as `NaN%` beside
+a finite `σ_k`, so Gabriel (1971) singular values appear to invent leftover-map
+axis share. ADR 0323 already omits share and singular value independently on
+grouping comparison leftover-axis badges. ADR 0324 already omits share and
+singular value independently on leftover-map graphic-display axes. Period
+leftover-axis badges still hide the σ-only copy `leftover axis {k} σ {value}`.
+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`.
+
+This increment captions leftover-axis report badges with already persisted
+leftover-map singular values independently of leftover-map axis share.
+Leftover-axis report badges stay `leftover axis {k} σ {value}` when share is
+omitted so they stay distinct from leftover-axis `leftover axis {k} σ {value} {share}%`
+(ADR 0322), from hyphen `leftover-map axis {k} σ {value}` (ADR 0324), from
+comparison leftover-axis `leftover map comparison leftover axis {k} σ {value}`
+(ADR 0323), and from comparison graphic
+`leftover map comparison graphic leftover-map axis {k} σ {value}`.
+It does not add columns. Do not invent a leftover score. Do not invent a
+theta.
+
+This protected increment uses **0325** so it does not collide with leftover-map
+singular values on leftover-map graphic-display axes (0324), leftover-map
+singular values on leftover-axis report badges on the grouping comparison
+strip (0323), leftover-map singular values on leftover-axis report badges
+(0322), leftover-map singular values on the grouping comparison leftover-map
+graphic (0321), leftover-map axis share persistence (0148), or the dashboard
+stacks.
+
+## Decision
+
+On leftover-axis report badges, caption leftover-map axis `k` with persisted
+leftover-map singular value `σ_k` when that singular value is finite and
+non-negative, including rank-0 zero singular values. Share and singular
+value omit independently: no share and no `σ_k` omits that leftover-axis
+report badge; share only is `leftover axis {k} {share}%`; `σ_k` only is
+`leftover axis {k} σ {value}`; both is `leftover axis {k} σ {value} {share}%`.
+A missing or non-finite leftover-map axis share omits that share caption and
+does not invent leftover-map axis share from `σ_k`. A missing, non-finite, or
+negative singular value omits that `σ` badge and keeps a usable leftover-axis
+share caption. Rank-0 unused axes still name `σ 0.00`. Click a leftover pair
+to open that post.
+
+Leftover-axis report badge leftover-map singular values omit independently of
+leftover-map graphic-display leftover-map axis singular values and leftover-map
+comparison leftover-axis singular values. A missing leftover-map axis share
+omits that leftover-axis share caption and keeps a usable leftover-axis `σ`
+caption, leftover-map graphic leftover-map axis `σ` caption, leftover-map
+comparison leftover-axis `σ` caption, leftover-map comparison graphic leftover-map
+axis `σ` caption, leftover-map graphic leftover-map axis ticks, leftover-map
+distance caption, leftover-map rank caption, leftover expected `E`, leftover
+observed `Y`, leftover residual `R`, leftover-map unexplained leftover `U`,
+leftover-map reconstruction `R̂`, and leftover-map graphic coverage notes.
+
+This increment does not change leftover-map singular values on leftover-map
+graphic-display axes. Those leftover-map graphic axes stay
+`leftover-map axis {axis} σ {value} ({share}%)` (ADR 0324). This increment does
+not change leftover-map singular values on leftover-axis report badges on the
+grouping comparison strip (ADR 0323). 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-axis report badges name persisted leftover-map
+singular values when finite even when leftover-map axis share is omitted;
+click a leftover pair opens that post. Hidden posts stay hidden. Rank-0 unused
+axes still name leftover-axis `σ 0.00`. Leftover-map graphic-display leftover-map
+singular values (ADR 0324), leftover-axis report badge leftover-map singular
+values with share (ADR 0322), and grouping comparison leftover-axis report
+badge leftover-map singular values (ADR 0323) remain.
