Phase 2 Plan 01: Ranking Tab Entry Point Summary

saveReorder append-only audit mutation + Ranking tab registered on EVALUATION round detail pages with RankingDashboard stub component

Performance

• Duration: ~5 min
• Started: 2026-02-27T00:15:00Z
• Completed: 2026-02-27T00:20:00Z
• Tasks: 2
• Files modified: 3

Accomplishments

• Added saveReorder adminProcedure to rankingRouter — accepts snapshotId, category, orderedProjectIds; appends ReorderEvent to reordersJson (append-only audit log)
• Registered Ranking tab in round detail page guarded by isEvaluation with BarChart3 icon (already imported)
• Created minimal RankingDashboard stub component that compiles and renders placeholder text

Task Commits

Each task was committed atomically:

1. Task 1: Add saveReorder mutation to ranking router - 68422e6 (feat)
2. Task 2: Register Ranking tab in round detail page + create component stub - 8f71527 (feat)

Plan metadata: (docs commit to follow)

Files Created/Modified

• src/server/routers/ranking.ts - Added ReorderEvent local type and saveReorder adminProcedure
• src/components/admin/round/ranking-dashboard.tsx - New stub component exporting RankingDashboard with competitionId+roundId props
• src/app/(admin)/admin/rounds/[roundId]/page.tsx - Import RankingDashboard, add Ranking tab to tab array, add TabsContent block

Decisions Made

• ReorderEvent type defined locally in ranking.ts (not exported) — only consumed by saveReorder
• Stub uses _competitionId / _roundId underscore prefix to avoid TypeScript unused-var warnings while keeping the correct prop signature for Plan 02 to use

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• saveReorder backend contract established and type-safe
• Ranking tab entry point wired — visible when viewing EVALUATION rounds
• Plan 02 can now replace the stub body with the full RankingDashboard component
• Build and typecheck both pass with 0 errors
