+- Grouping comparison rows now show persisted leftover-map incomplete-post count through `leftoverMapIncompletePostCount` (ADR 0293 / v2.50.0) only for a fully caller-visible persisted grouping. Partial visibility omits the aggregate; valid persisted zero remains visible, and the UI never derives dropped posts from scored-minus-used.

+
+This aggregate inherits ADR 0290's full-visible-grouping authorization boundary. Persisted incomplete-post count is shown only when the caller can see the full persisted grouping population; partial-visibility groupings omit it. Never recalculate a psychometric dropped-post count from the visible subset.
+
+## Context
+
+ADR 0168 already persists `incomplete_post_count` on
+`report_leftover_map_coverage`. ADR 0289 already captions leftover-map post
+complete-case coverage on the grouping comparison strip. ADR 0290 already
+captions leftover-map item complete-case coverage on the grouping comparison
+strip. ADR 0283 already names persisted leftover-map incomplete post coverage
+on the leftover-map graphic display. ADR 0286 already names it on the pair
+list. The strip still does not name dropped incomplete posts, so a buyer who
+compares leftover pairs can treat `used N of M scored posts (complete-case)`
+on a grouping row as the full scored census even after incomplete rows were
+dropped. Incomplete rows are dropped from Gabriel factorization; hiding
+dropped posts on the strip lets a sparse post with one missing criterion
+vanish without a next action.
+
+This increment captions persisted leftover-map incomplete post coverage on
+each grouping comparison row through leftoverMapIncompletePostCount. It does
+not add columns. It does not recompute dropped posts from scored minus used,
+leftover pair count, plotted marker count, leftover-map distance, or
+leftover-map rank. It does not persist leftover-map inner product, cosine, or
+length as separate columns. Do not invent a leftover score. Do not invent a
+theta.
+
+The dashboard stack already used neighbouring leftover facts under other
+numbers. This protected increment uses **0291** so it does not collide with
+leftover-map item complete-case coverage on the grouping comparison strip
+(0290), leftover-map complete-case coverage on the grouping comparison strip
+(0289), leftover-map post complete-case coverage fail-closed on the pair list
+(0288), leftover-map incomplete item coverage on the pair list (0287),
+leftover-map incomplete post coverage on the pair list (0286), leftover-map
+item complete-case coverage on the pair list (0285), leftover-map incomplete
+item coverage on the graphic display (0284), leftover-map incomplete post
+coverage on the graphic display (0283), leftover-map item complete-case
+coverage on the graphic display (0282), leftover-map complete-case coverage
+on the graphic display (0281), leftover-map rank on pair segments (0280),
+or the dashboard stacks.
+
+## Decision
+
+On the grouping comparison strip, caption leftover-map incomplete post
+coverage as `Leftover map dropped {dropped} incomplete posts` only when
+leftoverMapIncompletePostCount returns a usable dropped integer from
+persisted `incomplete_post_count`. Use the distinct accessible name
+`Leftover map comparison incomplete posts` so the strip caption is not the
+pair-list note (`Leftover map incomplete posts`) and is not the graphic
+caption (`Leftover-map graphic incomplete posts`). A missing coverage row, a
+non-integer dropped count, a negative dropped count, or a dropped count that
+contradicts usable complete-case integers (`dropped !== scored − used` when
+`map_post_count` / `scored_post_count` are usable) omits that leftover-map
+comparison incomplete post note and keeps the strip leftover-map post
+coverage note, leftover-map item coverage note, leftover pairs, leftover-map
+distance `d`, and any leftover-map captions on the pair list and graphic.
+Dropped `0` is shown when that persisted dropped count is a non-negative
+integer. Do not invent dropped posts from scored minus used, leftover pair
+count, plotted marker count, leftover-map distance, leftover-map rank,
+leftover-map post coverage, leftover-map item coverage, leftover-map
+incomplete item coverage, or the count of unused axes. Do not caption
+leftover-map incomplete item coverage on the strip in this increment. Do not
+add the leftover-map graphic to the strip. Click a leftover pair on the strip
+to open that post.
+
+Do not add SQL. Do not edit shipped migrations. Do not persist inner
+product, cosine, or length as separate columns. Do not invent a leftover
+score. Do not invent a theta.
+
+## Consequences
+
+After `make seed`, the grouping comparison strip names persisted leftover-map
+post complete-case coverage, persisted leftover-map item complete-case
+coverage, and persisted leftover-map incomplete post coverage on each grouping
+row when leftoverMapCoverageCounts / leftoverMapItemCoverageCounts /
+leftoverMapIncompletePostCount return usable integers, then names leftover
+pairs with leftover-map distance `d`. Closest and farthest leftover pairs
+still sit above the member list with the leftover-map graphic display; click a
+post marker or a pair button opens that post.
+Hidden posts stay hidden.
