Pending/approved replay is a no-op. | +| `GET /tournaments/:id/requests` | Host-only pending array/count, capacity, revision and lobby state. | +| `PATCH /tournaments/:id/request/:userId` | `action: approve/reject`; optional `requestCreatedAt` fences stale attempts. Legacy status approved/rejected accepted, never both fields. | +| `PATCH /tournaments/:id/stance` | Own admitted membership; stance for/against while lobby is open. | +| `GET /tournaments/:id/request` | Own-request status/timestamp without private host detail. | +| `POST /tournaments/:id/start` | Host-only `{}`; readiness/schedule checks, one frozen run; replay returns existing run. | +| `GET /tournaments/:id/execution` | Authorized phase/server-time/deadline and own receipts, not peer transcripts. | +| `POST /tournaments/:id/transcript` | `{runId,round,content}`; one immutable accepted input per person/eligible phase. | +| `GET /tournaments/:id/evaluation` | Protected read-only pending/running/completed/failed/legacy state and validated results; no manual judging trigger. | + +First join/private request uses 201/202 instead of #671's 200: clients must accept +HTTP success. Capacity/start conflicts are 409; private outsiders 404; malformed, +oversized, duplicate-key or unknown-field writes 400; invite/request limits 429. +Admission/settings/start share atomic revision and frozen-run guards. A rejected +user can atomically reapply before start with a newer timestamp and reset decision +metadata. At most 64 current request records, not an append-only history. Old +timestamps cannot decide a new attempt; unversioned actions target the current one. + +## Execution and Scoring + +Existing documents gain `schemaVersion`, `revision`, embedded `execution` and +`evaluation`. Missing revision means 0; no execution means lobby/legacy, not a +fabricated result. Start freezes valid names/stances on both sides and run ID. +Eight shared 180-second phases: opening for, opening against, cross-examination +question for, answer against, question against, answer for, closing for/against. +Each participant has four eligible phases. Canonical text is limited to 8192 UTF-8 +bytes and hashed; identical retries return receipts. Missing slots score 0; restart +recovery advances deadlines. Final closure queues exactly one evaluation record. + +Worker bounds: two slots/process, 150-second leases, 120-second job deadline, +three attempts maximum, bounded retries/corrective validation and run/hash/revision/ +lease fencing. Publication and completion are atomic, not exactly-once billing. +Criteria maxima 35/25/25/15: reasoning, relevance, phase skill, clarity. Server +derives totals out of 400/person, compares exact side means and returns draws/tied +individual winners independently of side outcome. Results are read-only/no-store; +polling never triggers judging. Browser speech is optional, not shared media. + +## Enablement and Acceptance Gates + +Evaluation is **disabled by default**; pending inputs are retained. Explicitly set +`TOURNAMENT_EVALUATION_ENABLED=true` and `TOURNAMENT_EVALUATION_MODEL` to a supported +model to use the configured Gemini key. Never commit secrets or enable paid calls +without approval. Provider inputs use aliases, bounded untrusted text and no tools; +strict parsing does not certify judging quality, fairness or prompt resistance. + +Before deployment, audit invite duplicates/index rights, backup/rollback, trusted +proxy/distributed throttles, clocks, concurrency/quota/cost, real authentication, +TLS, rubric/privacy and retention/consent. Accepted text is retained; no deletion, +appeals or reevaluation policy is invented. Plaintext browser drafts are isolated +by account/run/phase, not confidential from someone using the same device. + +## Existing Invite-Code Migration + +Startup intentionally stops if the required unique invite-code index cannot be +created. Do not ignore that error: private joins look up a tournament by code. +Before rollout, stop tournament writers, back up the collection, and run this +read-only audit in the intended database; its filter matches the partial index: + +```javascript +db.tournaments.aggregate([ + { $match: { visibility: "private", inviteCode: { $type: "string", $gt: "" } } }, + { $group: { _id: "$inviteCode", count: { $sum: 1 } } }, + { $match: { count: { $gt: 1 } } } +]) +``` + +For each conflict, identify the affected tournament IDs and coordinate with their +hosts before reissuing codes. Use approved six-digit replacements not already used +by another private tournament; update each intended ID only if its old code still +matches. Preserve tournaments, membership and requests, and have hosts redistribute +changed invitations. Rerun the audit until empty, then start the backend and verify +`unique_private_invite_code` exists with the expected unique/partial options before +restoring traffic. Automatic code rotation is deliberately not a startup action. + +## Validation + +Run `go test ./... -count=1` and `go vet ./...` from backend, and `npm run build` +and `npm test` / `npm run lint` from frontend. This contribution does not include +tournament-specific regression test files; these commands exercise the remaining +repository coverage. Local mock validation is not live-model evidence or proof of +production readiness. Never use production databases for testing. Full repository +lint has existing legacy failures; race instrumentation needs a compatible +64-bit C toolchain. diff --git a/frontend/src/App.tsx b/frontend/src/App.tsx index 83c61fa4..73c4b978 100644 --- a/frontend/src/App.tsx +++ b/frontend/src/App.tsx @@ -1,5 +1,5 @@ import { useContext } from "react"; -import { Routes, Route, Navigate, Outlet } from "react-router-dom"; +import { Routes, Route, Navigate, Outlet, useLocation } from "react-router-dom"; import { AuthProvider, AuthContext } from "./context/authContext"; import { ThemeProvider } from "./context/theme-provider"; // Pages @@ -24,6 +24,9 @@ import CoachPage from "./Pages/CoachPage"; import ChatRoom from "./components/ChatRoom"; import TournamentHub from "./Pages/TournamentHub"; import TournamentDetails from "./Pages/TournamentDetails"; +import TournamentRoom from "./Pages/TournamentRoom"; +import TournamentResults from "./Pages/TournamentResults"; +import { tournamentResultsReturnPath } from "./utils/tournamentReturnPath"; import ProsConsChallenge from "./Pages/ProsConsChallenge"; import TeamBuilder from "./Pages/TeamBuilder"; import TeamDebateRoom from "./Pages/TeamDebateRoom"; @@ -39,6 +42,7 @@ import CreateTournament from "./Pages/CreateTournament"; // Protects routes based on authentication status function ProtectedRoute() { + const location = useLocation(); const authContext = useContext(AuthContext); if (!authContext) { throw new Error("ProtectedRoute must be used within an AuthProvider"); @@ -47,7 +51,8 @@ function ProtectedRoute() { if (isLoading) { return ; } - return isAuthenticated ? : ; + const returnTo = tournamentResultsReturnPath(location.pathname); + return isAuthenticated ? : returnTo ? : ; } // Defines application routes @@ -100,6 +105,8 @@ function AppRoutes() { } /> } /> } /> + } /> + } /> } diff --git a/frontend/src/Pages/OnlineDebateRoom.tsx b/frontend/src/Pages/OnlineDebateRoom.tsx index e8987294..b6436418 100644 --- a/frontend/src/Pages/OnlineDebateRoom.tsx +++ b/frontend/src/Pages/OnlineDebateRoom.tsx @@ -202,8 +202,8 @@ const OnlineDebateRoom = (): JSX.Element => { const audioContextRef = useRef(null); const analyserRef = useRef(null); const animationRef = useRef(null); - const timerRef = useRef(null); - const judgePollRef = useRef(null); + const timerRef = useRef | null>(null); + const judgePollRef = useRef | null>(null); const copyTimeoutRef = useRef | null>(null); const submissionStartedRef = useRef(false); diff --git a/frontend/src/Pages/TeamDebateRoom.tsx b/frontend/src/Pages/TeamDebateRoom.tsx index 04f38e5a..34ae2856 100644 --- a/frontend/src/Pages/TeamDebateRoom.tsx +++ b/frontend/src/Pages/TeamDebateRoom.tsx @@ -300,7 +300,7 @@ const TeamDebateRoom: React.FC = () => { // Timer state const [timer, setTimer] = useState(0); - const timerRef = useRef(null); + const timerRef = useRef | null>(null); // Speech recognition state const [isListening, setIsListening] = useState(false); diff --git a/frontend/src/Pages/TournamentDetails.tsx b/frontend/src/Pages/TournamentDetails.tsx index 6bf27fe0..8d2fad02 100644 --- a/frontend/src/Pages/TournamentDetails.tsx +++ b/frontend/src/Pages/TournamentDetails.tsx @@ -1,17 +1,103 @@ -import TournamentBracket from './TournamentBracketPage'; -import MatchLogs from './MatchLogs'; +import { useContext, useEffect, useRef, useState } from "react"; +import { Link, useNavigate, useParams } from "react-router-dom"; +import { useAtomValue } from "jotai"; +import { ArrowLeft, Check, Copy, Play, RefreshCw, Trash2, Trophy, X } from "lucide-react"; +import { AuthContext } from "@/context/authContext"; +import { userAtom } from "@/state/userAtom"; +import { chooseTournamentStance, decideTournamentRequest, deleteTournament, getTournament, joinTournament, startTournament, TournamentRequestError, type CreatedTournament } from "@/services/tournamentService"; -export default function BracketWithLogs() { - return ( -
