Review comments at @frontend/src/Pages/TournamentBracketPage.tsx:
- Around line 197-201: Update the tournament rendering condition around
firstRoundMatches so the empty message checks tournament.participants.length ===
0, while the open-slot grid remains rendered whenever firstRoundMatches.length >
0.
- Around line 62-86: Update the useEffect and its loadTournament flow to track
cancellation and return cleanup that marks the effect inactive when id changes
or the component unmounts. Guard setTournament, setError, and setLoading(false)
so stale requests cannot update state, while preserving the existing behavior
for the current tournament request.
- Around line 119-125: Update the first-round match construction and rendering
to treat a missing opponent beyond slots.length as a bye rather than an open
participant slot. Add an isBye marker when index + 1 exceeds the available
slots, then render “Bye” instead of Participant for match.player2 when that
marker is set; preserve normal participant rendering for all other matches.
Review comments at @frontend/src/Pages/TournamentHub.tsx:
- Around line 183-185: Update the empty-state rendering in TournamentHub so it
appears only when loading is false, error is absent, and
visibleTournaments.length is zero; keep the existing loading and error displays
unchanged.
Review comments at @frontend/src/services/tournamentService.ts:
- Around line 106-127: Normalize nullable participants in both getTournaments
and getTournamentById before returning tournament data, mapping each tournament
so participants is an empty array when the API returns null while preserving all
other fields and the existing top-level array behavior.

Fixed in 90c9529. Avatar visibility and overflow are now calculated from the actual participants.length instead of maxParticipants, so +N only represents real hidden participants. npx tsc -b and npm run build both pass. |

🟡 Minor · Render a Bye only for an occupied final slot. · TournamentBracketPage.tsx:132-138
frontend/src/Pages/TournamentBracketPage.tsx:132-138
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winRender a Bye only for an occupied final slot.
A tournament can use the default odd capacity of 11, and neither the form nor backend rejects odd values. When the final slot is unused, the last match renders
Open slotforplayer1andByefor the nonexistentplayer2. A Bye is only correct when the final real slot contains a participant. This conflicts with the requirement to show unused positions as open slots.Suggested fix

Summary of Changes
This PR removes the hardcoded/mock tournament data from the Tournament Arena and Tournament Bracket pages and wires the existing frontend to the real tournament backend APIs.
Changes include:
GET /tournamentsPOST /tournaments/:id/joinwhen joining a public tournamentHostingfor the tournament hostJoinedfor existing participantsFullwhen participant capacity is reachedJoin Tournamentwhen the tournament is availableGET /tournaments/:idAddressed Issues:
Fixes #734
Screenshots/Recordings:
Before
Different tournament IDs displayed the same hardcoded participants and champion.
Tournament 1:
Tournament 6:
Both tournament routes displayed the same participants and champion despite using different tournament IDs.
After
The Tournament Arena now displays tournaments returned by the backend and reflects the authenticated user's actual relationship to each tournament.
I also tested the public tournament flow using a second authenticated account. The tournament was visible to the second account, and that account was able to join successfully.

End-to-end verification:
HostingJoinedAdditional Notes:
The current tournament API does not expose persisted bracket winners or champion data on
main, so this PR intentionally does not fabricate tournament results.This PR does not implement bracket generation or progression logic. That work is separate from this issue and has related ongoing work in #654 and #690.
The existing Past Tournament "View Tournament" button issue is also not duplicated here because it is already being addressed separately in #726.
