+# Phase 2 Plan 03: Advance Top N Dialog + Batch-Reject Summary
+
+**Advance Top N dialog with per-category numeric inputs, optional batch-reject checkbox, and disabled state tied to pending reorder mutations — completing the full advancement workflow for the RankingDashboard**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-02-27T08:51:01Z
+- **Completed:** 2026-02-27T08:56:00Z
+- **Tasks:** 1
+- **Files modified:** 1
+
+## Accomplishments
+
+- DASH-05: Admin can click "Advance Top N" button to open a dialog, enter a number N per category, and advance the top N projects from each category to the next round
+- DASH-06: Admin can enable "Also batch-reject non-advanced projects" checkbox in the dialog — fires batchTransition for non-advanced projects; toasts use `.succeeded.length` per MEMORY.md
+- DASH-07: Advance button is disabled while `saveReorderMutation.isPending` is true (reorder in flight) and when no snapshot exists
+- pendingReorderCount ref added to saveReorderMutation (onMutate++, onSettled--) for belt-and-suspenders reorder tracking
+- Full dialog: per-category N inputs with range clamping, live preview of advance/reject counts, cancel/confirm buttons
+- Both mutations invalidate `roundEngine.getProjectStates` on success to refresh downstream state
+- TypeScript strict mode: 0 errors; build: PASSED

+## Task Commits
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Add Advance Top N dialog + batch-reject to RankingDashboard | a6f3945 | src/components/admin/round/ranking-dashboard.tsx |
+
+## Files Created/Modified
+
+- `src/components/admin/round/ranking-dashboard.tsx` — Added Dialog, Input, Label imports; pendingReorderCount ref; advanceMutation; batchRejectMutation; handleAdvance; Advance Top N button; Dialog JSX (681 lines total, +197 insertions)
+
+## Decisions Made
+
+- **Advance button disabled state uses `saveReorderMutation.isPending`** (reactive) as the primary signal, not `pendingReorderCount.current` (useRef is not reactive — React won't re-render on ref mutation). The ref still provides belt-and-suspenders for rapid multi-drag scenarios but is not the gating signal.
+- **topNStartup + topNConceptual === 0** disables the confirm button inside the dialog — prevents a no-op advance call when both inputs are zero.
+- **batchRejectMutation fires conditionally** — only when `includeReject` is true AND `rejectIds.length > 0`. Avoids sending an empty projectIds array to the mutation.

+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All 7 DASH requirements (DASH-01 through DASH-07) completed across plans 01-03
+- Phase 2 (Ranking Dashboard UI) is fully complete
+- Phase 3 (Notification Templates) or Phase 4 (Juror Criterion Progress) can begin next
