Add bracket seeding tests and implement tournament-style seeding for 16 and 32-team brackets

- Introduced `generateStandardSeeding()` function to create proper tournament matchups (e.g., 1v16, 8v9). - Added comprehensive tests for 4, 8, 16, and 32-team brackets to ensure correct seeding and balance. - Updated testing instructions to reflect new features and improvements in bracket generation. - Fixed issues with sequential seeding and ensured all matchups sum to n+1 for balance. - Implemented batch winner selection and duplicate participant prevention for improved user experience. - Enhanced fantasy points display on event pages for better visibility of participant results.

+# Phase 2.7 Testing Instructions
+
+**Phase:** 2.7 - Simple Template Expansion (16, 32 teams)
+**Status:** Completed
+**Date:** 2025-01-04
+
+## Overview
+
+Phase 2.7 adds support for larger bracket templates (16-team and 32-team) with non-scoring rounds. Only participants who reach the Elite Eight (top 8) score fantasy points. Early eliminations receive 0 points per Q20.
+
+## Phase 2.7 Testing Checklist
+
+### 1. **Bracket Generation UI** (`/admin/sports-seasons/:id/events/:eventId/bracket`)
+
+**Test the template selector:**
+- [ ] Navigate to a playoff event that has no bracket yet
+- [ ] See a "Bracket Template" dropdown with all options:
+  - Simple 4-Team Bracket - 4 teams
+  - Simple 8-Team Bracket - 8 teams
+  - Simple 16-Team Bracket - 16 teams
+  - Simple 32-Team Bracket - 32 teams
+  - NCAA March Madness (68 teams) - 68 teams
+  - NFL Playoffs (14 teams) - 14 teams
+  - NBA Playoffs (16 teams) - 16 teams
+- [ ] Change template selection - participant count should update dynamically
+- [ ] See round progression text (e.g., "Rounds: Round of 16 → Quarterfinals → Semifinals → Finals")
+
+### 2. **16-Team Bracket Creation**
+
+**Generate a 16-team bracket:**
+- [ ] Select "Simple 16-Team Bracket"
+- [ ] Fill in 16 participants (seeds 1-16)
+- [ ] Click "Generate Bracket"
+- [ ] Verify success message
+
+**Check bracket structure:**
+- [ ] See "Round of 16" section with 8 matches
+- [ ] See "Quarterfinals" section with 4 matches (TBD participants)
+- [ ] See "Semifinals" section with 2 matches (TBD participants)
+- [ ] See "Finals" section with 1 match (TBD participants)
+
+**Complete Round of 16:**
+- [ ] Set winners for all 8 matches
+- [ ] Winners should auto-advance to Quarterfinals
+- [ ] Click "Complete Round & Calculate Placements"
+- [ ] Select "Round of 16" from dropdown
+- [ ] Verify **8 losers get 0 fantasy points** (early elimination per Q20)
+
+**Complete Quarterfinals:**
+- [ ] Set winners for all 4 matches
+- [ ] Winners advance to Semifinals
+- [ ] Complete the round
+- [ ] Verify **4 losers share 5th-8th place** (20 points each with default scoring)
+
+**Complete Semifinals:**
+- [ ] Set winners for 2 matches
+- [ ] Winners advance to Finals
+- [ ] Complete the round
+- [ ] Verify **2 losers share 3rd-4th place** (45 points each)
+
+**Complete Finals:**
+- [ ] Set winner
+- [ ] Complete the round
+- [ ] Verify **winner gets 1st** (100 points), **loser gets 2nd** (70 points)
+- [ ] Navigate back to event detail page (click "Back to Event" or navigate to `/admin/sports-seasons/{id}/events/{eventId}`)
+- [ ] See new "Fantasy Points Awarded" card showing all participant results with positions and points
+- [ ] Verify early eliminations show "Early Elimination" with 0 points
+- [ ] Verify top 8 finishers show correct positions (1st-8th) with correct point totals
+
+### 3. **Batch Winner Selection (NEW)**
+
+**Test the batch winner selection UI:**
+- [ ] Navigate to any generated bracket (16 or 32-team)
+- [ ] See winner dropdowns for each incomplete match
+- [ ] Select a winner for one match - verify no submit button appears yet
+- [ ] Select winners for 2-3 matches in a round
+- [ ] Verify "Save X Winner(s) for [Round]" button appears
+- [ ] Click the batch save button
+- [ ] Verify success message shows correct count
+- [ ] Verify all selected winners are set
+- [ ] Verify winners auto-advance to next round
+- [ ] Verify winner dropdowns are cleared after submission
+
+**Test error handling:**
+- [ ] Try to submit with no winners selected - should not see button
+- [ ] Select winners for matches in different rounds - each round has separate button
+- [ ] Test partial success scenario (if possible to trigger)
+
+**Test workflow efficiency:**
+- [ ] Set all 8 winners for Round of 16 at once
+- [ ] Verify all 8 winners advance to Quarterfinals correctly
+- [ ] Set all 4 Quarterfinals winners at once
+- [ ] Verify advancement and placement calculation
+
+### 4. **32-Team Bracket Creation**
+
+**Generate a 32-team bracket:**
+- [ ] Select "Simple 32-Team Bracket"
+- [ ] Fill in 32 participants
+- [ ] Generate bracket
+- [ ] See 5 rounds: Round of 32 → Round of 16 → Quarterfinals → Semifinals → Finals
+
+**Test non-scoring rounds:**
+- [ ] Complete Round of 32 (16 matches)
+- [ ] Verify **16 losers get 0 points** (non-scoring round)
+- [ ] Complete Round of 16 (8 matches)
+- [ ] Verify **8 losers get 0 points** (non-scoring round)
+- [ ] Complete Quarterfinals through Finals
+- [ ] Verify scoring matches Q20: Only top 8 finishers get points
+
+**Final tally check:**
+- [ ] Total participants: 32
+- [ ] Participants with 0 points: 24 (Round of 32 + Round of 16 losers)
+- [ ] Participants scoring: 8 (QF losers through Champion)
+
+### 4. **Template-Based Advancement**
+
+**Verify auto-advancement works:**
+- [ ] In any multi-round bracket, set a winner in Round 1
+- [ ] Check that winner appears in correct slot in Round 2
+- [ ] Match advancement pattern:
+  - Match 1 winner → Next round Match 1, Participant 1
+  - Match 2 winner → Next round Match 1, Participant 2
+  - Match 3 winner → Next round Match 2, Participant 1
+  - Match 4 winner → Next round Match 2, Participant 2
+
+### 5. **Scoring Calculator Integration**
+
+**Check participant results:**
+- [ ] After completing a round, check database `participantResults` table
+- [ ] Non-scoring round losers should have `finalPosition = 0`
+- [ ] Scoring round participants should have correct placements (1-8)
+
+**Verify team standings update:**
+- [ ] If you have teams that drafted these participants
+- [ ] Check that standings recalculate after each round completion
+- [ ] Early elimination participants (0 points) should not add to team score
+
+### 6. **Error Handling**
+
+**Test validation:**
+- [ ] Try to generate bracket without selecting all participants → error
+- [ ] Try to select same participant twice → "Each participant can only be selected once"
+- [ ] Try to set winner when participants aren't assigned → should be disabled
+- [ ] Try to complete round with incomplete matches → error
+
+### 7. **Backward Compatibility**
+
+**Test existing 4 and 8 team brackets:**
+- [ ] Generate a "Simple 4-Team Bracket" → should work as before
+- [ ] Generate a "Simple 8-Team Bracket" → should work as before
+- [ ] All rounds should be scoring rounds for these templates
+- [ ] No 0-point eliminations (all 4 or 8 participants score)
+
+## Viewing Fantasy Points (NEW)
+
+After completing rounds and calculating placements, you can view the fantasy points awarded:
+
+**Navigation:**
+1. From the bracket management page, click "Back to Event"
+2. Or navigate to `/admin/sports-seasons/{sportsSeasonId}/events/{eventId}`
+
+**Fantasy Points Awarded Card:**
+- Shows all participants with calculated fantasy points
+- Sorted by final position (1st place at top)
+- Displays position with medals (🥇🥈🥉) for top 3
+- Shows "Early Elimination" for participants with 0 points (early knockout)
+- Points displayed in green for scoring participants, gray for 0 points
+
+**Example Display:**
+```
+Final Position | Participant      | Fantasy Points
+1st 🥇        | Arizona          | 100 pts
+2nd 🥈        | UConn            | 70 pts
+3rd 🥉        | Houston          | 45 pts
+4th           | Duke             | 45 pts
+5th           | Kansas           | 20 pts
+6th           | Purdue           | 20 pts
+7th           | Tennessee        | 20 pts
+8th           | North Carolina   | 20 pts
+Early Elim.   | UCLA             | 0 pts
+Early Elim.   | Alabama          | 0 pts
+...
+```
+
+**Note:** Team standings (total points across all events) are not yet displayed in the UI but are being calculated and stored in the database.
+
+## Key Expected Behaviors
+
+### Non-Scoring Rounds (Q20)
+- Round of 16 in 16-team bracket: 8 teams get 0 points
+- Round of 32 + Round of 16 in 32-team bracket: 24 teams get 0 points
+- Early eliminations don't count toward team standings
+
+### Scoring Rounds
+- Only Quarterfinals and beyond score fantasy points
+- Always exactly 8 participants score (1st through 8th)
+- Point distribution per default scoring:
+  - 1st: 100, 2nd: 70
+  - 3rd/4th (avg): 45 each
+  - 5th-8th (avg): 20 each
+  - Total: 340 points
+
+### Template Storage
+- Check `scoringEvents` table has `bracketTemplateId` stored
+- Check `scoringEvents` table has `scoringStartsAtRound` stored
+- Check `playoffMatches` have `isScoring` flag set correctly
+
+## Things NOT to Test Yet (Phase 2.8+)
+
+- ❌ NCAA 68-team bracket generation (won't assign participants correctly)
+- ❌ NFL 14-team with bye weeks
+- ❌ First Four play-in games
+- ❌ TBD slot handling
+
+## Database Verification Queries
+
+```sql
+-- Check event has template ID stored
+SELECT id, name, bracketTemplateId, scoringStartsAtRound
+FROM scoring_events
+WHERE id = 'your-event-id';
+
+-- Check matches have isScoring flag
+SELECT round, matchNumber, isScoring, participant1Id, participant2Id, winnerId
+FROM playoff_matches
+WHERE scoringEventId = 'your-event-id'
+ORDER BY round, matchNumber;
+
+-- Check participant results after round completion
+SELECT p.name, pr.finalPosition, pr.qualifyingPoints
+FROM participant_results pr
+JOIN participants p ON p.id = pr.participantId
+WHERE pr.sportsSeasonId = 'your-sports-season-id'
+ORDER BY pr.finalPosition;
+
+-- Check team standings
+SELECT t.name, ts.totalPoints, ts.currentRank,
+       ts.firstPlaceCount, ts.secondPlaceCount, ts.thirdPlaceCount, ts.fourthPlaceCount,
+       ts.fifthPlaceCount, ts.sixthPlaceCount, ts.seventhPlaceCount, ts.eighthPlaceCount
+FROM team_standings ts
+JOIN teams t ON t.id = ts.teamId
+WHERE ts.seasonId = 'your-season-id'
+ORDER BY ts.currentRank;
+```
+
+## Bug Fixes
+
+### Bug #1: Round of 16 and other non-standard rounds not displaying (Fixed)
+**Issue:** When creating a 16-team bracket, only Quarterfinals, Semifinals, and Finals were displayed. Round of 16 was missing.
+
+**Root Cause:**
+- Client component had hardcoded rounds array: `["Quarterfinals", "Semifinals", "Finals"]`
+- Server validation also had hardcoded round checking
+
+**Fix:**
+- Changed to dynamically get rounds from actual matches: `Array.from(new Set(matches.map(m => m.round)))`
+- Updated server validation to check if round exists in matches instead of hardcoding allowed values
+- Files changed:
+  - `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.tsx` (line 54)
+  - `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.server.ts` (lines 178-196)
+
+**Status:** ✅ Fixed and tested.
+
+### Bug #2: Sequential seeding instead of tournament-style seeding (Fixed)
+**Issue:** When creating a 16-team bracket with participants seeded 1-16, the bracket showed:
+- Match 1: Seed 1 vs Seed 2 (Arizona vs Atlanta)
+- Match 2: Seed 3 vs Seed 4
+- etc.
+
+Instead of proper tournament seeding:
+- Match 1: Seed 1 vs Seed 16
+- Match 2: Seed 8 vs Seed 9
+- etc.
+
+**Root Cause:**
+- Bracket generation assigned participants sequentially instead of using standard tournament seeding algorithm
+
+**Fix:**
+- Added `generateStandardSeeding()` function that creates balanced bracket matchups
+- Algorithm ensures:
+  - All matchups sum to n+1 (e.g., 1v16, 2v15, 3v14 all sum to 17 for 16 teams)
+  - Top seeds are separated into different bracket regions
+  - Balanced pods for each quarterfinal section
+- Added `seedInfo` field to store display text (e.g., "1 vs 16")
+- Works for 4, 8, 16, and 32-team brackets
+- Non-standard sizes (68, 14) fall back to sequential until custom logic is implemented
+
+**Files changed:**
+- `app/models/playoff-match.ts` (lines 255-369)
+- New test file: `app/models/__tests__/bracket-seeding.test.ts` (14 tests)
+
+**Status:** ✅ Fixed and tested. All 221 tests passing.
+
+### QOL Improvement: Duplicate participant prevention (Implemented)
+**Feature:** When selecting participants for bracket seeds, once a participant is selected for one seed, they are automatically removed from the dropdown options for all other seeds.
+
+**How it works:**
+- Each seed dropdown only shows participants that haven't been selected yet
+- If you select "Arizona" as Seed 1, "Arizona" disappears from all other seed dropdowns
+- Changing the bracket template resets all selections
+- Real-time updates as you make selections
+
+**Benefits:**
+- Prevents duplicate selections (the server already validated this, but now it's prevented in the UI)
+- Clearer UX - you can see which participants are still available
+- Faster bracket setup - no need to remember which teams you've already picked
+
+**Files changed:**
+- `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.tsx` (lines 40-68, 141, 167-190)
+  - Added `selectedParticipants` state to track selections
+  - Added `handleTemplateChange` to reset selections on template change
+  - Added `handleParticipantChange` to update selections
+  - Added `getAvailableParticipants` to filter out selected participants
+  - Updated Select components to use controlled state and filtered options
+
+**Status:** ✅ Implemented and tested. All 221 tests passing.
+
+### QOL Improvement #2: Batch winner selection (Implemented)
+**Feature:** Instead of having individual "Set" buttons for each match, users can now select winners for multiple matches in a round and submit them all with a single button click.
+
+**How it works:**
+- Each match in a round has a winner dropdown (controlled component)
+- Select winners for one or more matches
+- A "Save X Winner(s) for [Round]" button appears at the bottom of the round card
+- Click the button to submit all selected winners at once
+- Winners are automatically advanced to the next round
+- Selected winners are cleared after successful submission
+
+**Benefits:**
+- Faster workflow - set multiple winners at once instead of one at a time
+- Better UX - clear visual indication of pending selections
+- Fewer page reloads - batch submission reduces server round trips
+- Consistent advancement - all winners advance in a single operation
+
+**Implementation details:**
+- Client-side state tracking with `selectedWinners` state
+- Server-side batch processing with new "set-round-winners" intent
+- Automatic state cleanup after successful submission via useEffect
+- Error handling for partial success scenarios
+
+**Files changed:**
+- `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.tsx` (lines 1-2, 40-51, 294-334)
+  - Added useEffect import
+  - Added batch winner state management
+  - Replaced Form-wrapped Select with controlled Select components
+  - Added batch submit button per round
+  - Added useEffect to clear selections after success
+- `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.server.ts` (lines 175-276)
+  - Added "set-round-winners" intent handler
+  - Processes multiple winner assignments in batch
+  - Handles partial success with detailed error messages
+
+**Status:** ✅ Implemented and tested. All 221 tests passing.
+
+### QOL Improvement #3: Fantasy points display on event page (Implemented)
+**Feature:** After completing rounds and calculating placements, users can now view the fantasy points awarded to each participant on the event detail page.
+
+**How it works:**
+- Navigate to the event detail page (`/admin/sports-seasons/{id}/events/{eventId}`)
+- See "Fantasy Points Awarded" card with all participant results
+- Sorted by final position (1st place at top)
+- Shows position, participant name, and fantasy points
+- Early eliminations (0 points) clearly marked
+
+**Benefits:**
+- Instant verification of point calculations
+- Visual confirmation of bracket completion
+- Easy reference for standings verification
+- Clear distinction between scoring and non-scoring participants
+
+**Implementation details:**
+- Loader fetches `participant_results` from database
+- Includes participant relation for name display
+- Client sorts by `finalPosition` ascending
+- Displays medals for top 3 finishers
+- Color-codes points (green for scoring, gray for 0)
+
+**Files changed:**
+- `app/routes/admin.sports-seasons.$id.events.$eventId.server.ts` (lines 1, 16, 31-43)
+  - Added import for `findParticipantResultsBySportsSeasonId`
+  - Added `participantResults` to loader return data
+- `app/routes/admin.sports-seasons.$id.events.$eventId.tsx` (lines 38, 292-368)
+  - Added `participantResults` to destructured loader data
+  - Added "Fantasy Points Awarded" card with table
+  - Displays position, participant, and points with proper formatting
+
+**Status:** ✅ Implemented and tested. All 221 tests passing.
+
+### Bug #3: Round cards displaying in wrong order (Fixed)
+**Issue:** When setting a winner in Round of 16, the round cards would shuffle and display in incorrect order (e.g., "Semifinals, Quarterfinals, Round of 16, Finals" instead of chronological order).
+
+**Root Cause:**
+- Rounds were being displayed in the order they appeared from the database query
+- Database ordering was based on match results, not chronological tournament progression
+- As matches completed and were updated, the database result order could change
+
+**Fix:**
+- Added `getOrderedRounds()` function that uses the bracket template's round order
+- If event has a `bracketTemplateId`, uses the template's chronological round order
+- Filters to only show rounds that have matches
+- Falls back to database order if no template is available
+
+**How it works now:**
+1. Get unique rounds from matches
+2. If event has bracket template, get template
+3. Use template's round order (first round → finals)
+4. Filter to only rounds that exist in matches
+5. Display cards in correct chronological order
+
+**Example:**
+- **16-team bracket:** Round of 16 → Quarterfinals → Semifinals → Finals
+- **32-team bracket:** Round of 32 → Round of 16 → Quarterfinals → Semifinals → Finals
+- Order remains stable even as matches are completed
+
+**Files changed:**
+- `app/routes/admin.sports-seasons.$id.events.$eventId.bracket.tsx` (lines 23, 79-98, 221, 330)
+  - Imported `getBracketTemplate`
+  - Added `getOrderedRounds()` function
+  - Updated round mapping to include type annotations
+
+**Status:** ✅ Fixed and tested. All 221 tests passing.
+
+## Known Issues
+
+None at this time. All 221 tests passing (207 original + 14 seeding tests).
+
+## Notes
+
+- Phase 2.8 will add full NCAA 68-team bracket support with First Four play-in games
+- NFL 14-team and NBA 16-team templates exist but need bye week logic (Phase 2.9)
