+# ADR 0026 — Name leftover pair context on the opened post
+
+**Decision status:** Accepted
+**Date:** 2026-08-17
+
+## Context
+
+ADR 0018 puts closest and farthest leftover pairs above the period-report
+member list. Clicking a pair opened the post, but the popup did not name
+why the buyer landed there. The evaluation list showed criterion scores
+without marking the leftover criterion, so “Open this post to read the
+criterion it sat closest to” had no next action on the destination.
+
+## Decision
+
+When the loaded period-report payload includes leftover pairs for the
+open post, the popup names that leftover map result and marks the
+matching evaluation row.
+
+1. `ReportsPanel` lifts authorized `leftover_pairs` into `PostList`.
+   A report fetch error clears the list — never an invented pair.
+2. The popup status is
+   `This post sat closest to {criterion} after main effects. Read that
+   evaluation row next.` (or `farthest from`).
+3. The evaluation row whose `criterion_code` matches a leftover pair
+   shows `Closest leftover` or `Farthest leftover`. Other rows stay
+   unmarked.
+4. Opening the same post from the member list, home list, or leftover
+   button uses the same loaded report evidence. A post that is not a
+   leftover pair shows no leftover copy.
+
+Do not invent leftover numbers. Do not persist a second leftover store.
+Do not mix this into #74 or #92.
+
+## Consequences
+
+After `make seed`, opening the closest leftover pair (or that same
+member) names the leftover criterion and points at the evaluation row.
+Mean θ stays on the report panel. Rankings stay on ADR 0024. TEPP stays
+on #214.

+# ADR 0027 — Focus the leftover evaluation row on the opened post
+
+**Decision status:** Accepted
+**Date:** 2026-08-17
+
+## Context
+
+ADR 0026 names leftover pair context on the opened post and marks the
+matching evaluation row. The status still says “Read that evaluation
+row next,” but the row stayed wherever it sat in the list. A long
+rubric buries the leftover criterion under the fold.
+
+## Decision
+
+When leftover pairs for the open post match an evaluation row, that
+row is the current evaluation item and receives focus.
+
+1. A leftover-matching row sets `aria-current="true"` and the
+   leftover badge from ADR 0026.
+2. The first leftover pair in the loaded report payload is the
+   focus target. When the host provides layout,
+   `scrollIntoView({ block: "nearest" })` runs; keyboard
+   `tabIndex={-1}` focus always runs. Later leftover rows stay
+   marked, not invented.
+3. A post with no leftover pair, or a row whose criterion does not
+   match, is not current and is not focused.
+
+Do not invent leftover numbers. Do not persist a second leftover
+store. Do not mix this into #74 or #92.
+
+## Consequences
+
+After `make seed`, opening the closest leftover pair moves keyboard
+focus to the sales-lead evaluation row. Mean θ stays on the report
+panel. Rankings stay on ADR 0024. TEPP stays on #214.
