+# NowChess Tournament API
+
+Swiss-system bot tournaments. Bots are paired by score each round; all bots play every round (no eliminations). Game moves flow through the existing board and bot endpoints — the tournament module only orchestrates pairings, standings, and lifecycle.
+
+---
+
+## Base path
+
+```
+/api/tournament
+```
+
+Routing: `/api/tournament` → `nowchess-tournament-active:8086`
+
+---
+
+## Authentication
+
+All endpoints require a valid JWT (`Authorization: Bearer <token>`).  
+Bot-facing streaming endpoints additionally require the token's subject to match the registered `botId`.
+
+---
+
+## Data models
+
+### Tournament
+
+```json
+{
+  "id": "t7kXq2",
+  "name": "Friday Night Bots",
+  "status": "created | started | finished",
+  "rounds": 5,
+  "currentRound": 2,
+  "timeControl": {
+    "limitSeconds": 300,
+    "incrementSeconds": 3
+  },
+  "createdBy": "userId",
+  "createdAt": "2026-05-13T18:00:00Z",
+  "startedAt": "2026-05-13T18:05:00Z",
+  "finishedAt": null
+}
+```
+
+### Standing
+
+```json
+{
+  "rank": 1,
+  "botId": "bot_abc",
+  "botName": "StockfishClone",
+  "points": 3.5,
+  "wins": 3,
+  "draws": 1,
+  "losses": 0,
+  "buchholz": 9.0
+}
+```
+
+Tiebreaker: Buchholz score (sum of opponents' points).
+
+### Pairing
+
+```json
+{
+  "round": 2,
+  "whiteBot": "bot_abc",
+  "blackBot": "bot_xyz",
+  "gameId": "j0nPtcjl",
+  "result": "white | black | draw | ongoing"
+}
+```
+
+### TournamentEvent (SSE)
+
+```json
+{ "type": "tournamentStarted", "tournamentId": "t7kXq2" }
+{ "type": "roundStarted",      "tournamentId": "t7kXq2", "round": 2 }
+{ "type": "pairingReady",      "tournamentId": "t7kXq2", "round": 2, "gameId": "j0nPtcjl", "color": "white" }
+{ "type": "roundFinished",     "tournamentId": "t7kXq2", "round": 2 }
+{ "type": "tournamentFinished","tournamentId": "t7kXq2" }
+```
+
+---
+
+## Endpoints
+
+### Tournament lifecycle
+
+#### Create tournament
+
+```
+POST /api/tournament
+```
+
+Body:
+
+```json
+{
+  "name": "Friday Night Bots",
+  "rounds": 5,
+  "timeControl": {
+    "limitSeconds": 300,
+    "incrementSeconds": 3
+  }
+}
+```
+
+Response `201 Created`:
+
+```json
+{ "id": "t7kXq2" }
+```
+
+The creator becomes the tournament director. Only the director can start and delete the tournament.
+
+---
+
+#### Get tournament
+
+```
+GET /api/tournament/{tournamentId}
+```
+
+Response `200 OK`: `Tournament` object.
+
+---
+
+#### List tournaments
+
+```
+GET /api/tournament
+```
+
+Query params:
+
+| Param    | Type                            | Default   |
+|----------|---------------------------------|-----------|
+| `status` | `created\|started\|finished`    | (all)     |
+| `limit`  | integer (max 50)                | 20        |
+| `offset` | integer                         | 0         |
+
+Response `200 OK`:
+
+```json
+{
+  "tournaments": [ /* Tournament[] */ ],
+  "total": 42
+}
+```
+
+---
+
+#### Start tournament
+
+```
+POST /api/tournament/{tournamentId}/start
+```
+
+Requires at least 2 registered bots. Computes round 1 pairings (random for round 1; score-based from round 2). Creates one game per pairing via `POST /api/board/game`.
+
+Response `200 OK`: updated `Tournament` object.
+
+---
+
+#### Delete tournament
+
+```
+DELETE /api/tournament/{tournamentId}
+```
+
+Only allowed while `status == "created"`. Response `204 No Content`.
+
+---
+
+### Bot registration
+
+#### Register bot
+
+```
+POST /api/tournament/{tournamentId}/bots
+```
+
+Registers a bot for the tournament. Must be called before the tournament starts.  
+The token subject must match the bot being registered.
+
+Body:
+
+```json
+{ "botId": "bot_abc" }
+```
+
+Response `200 OK`:
+
+```json
+{ "botId": "bot_abc", "tournamentId": "t7kXq2" }
+```
+
+---
+
+#### Unregister bot
+
+```
+DELETE /api/tournament/{tournamentId}/bots/{botId}
+```
+
+Only allowed while `status == "created"`. Response `204 No Content`.
+
+---
+
+#### List registered bots
+
+```
+GET /api/tournament/{tournamentId}/bots
+```
+
+Response `200 OK`:
+
+```json
+{
+  "bots": [
+    { "botId": "bot_abc", "botName": "StockfishClone" }
+  ]
+}
+```
+
+---
+
+### Standings and pairings
+
+#### Get standings
+
+```
+GET /api/tournament/{tournamentId}/standings
+```
+
+Response `200 OK`:
+
+```json
+{ "standings": [ /* Standing[] */ ] }
+```
+
+---
+
+#### Get pairings for a round
+
+```
+GET /api/tournament/{tournamentId}/rounds/{round}/pairings
+```
+
+Response `200 OK`:
+
+```json
+{ "pairings": [ /* Pairing[] */ ] }
+```
+
+---
+
+### Bot streaming
+
+#### Stream tournament events
+
+```
+GET /api/tournament/{tournamentId}/stream
+```
+
+Headers: `Accept: text/event-stream`
+
+Server-Sent Events stream scoped to this tournament. The bot receives `pairingReady` events when it is assigned a game, at which point it should connect to the existing bot game stream:
+
+```
+GET /bot/stream/game/{gameId}    (existing endpoint)
+POST /bot/game/{gameId}/move/{uci}  (existing endpoint)
+```
+
+The tournament module never sends moves — bots do that themselves through the existing bot endpoints.
+
+---
+
+## Typical bot flow
+
+```
+1. POST /api/tournament                          # director creates tournament
+2. POST /api/tournament/{id}/bots               # each bot registers
+3. POST /api/tournament/{id}/start              # director starts
+4. GET  /api/tournament/{id}/stream  (SSE)      # each bot opens stream
+
+   -- per round --
+5. receive: pairingReady { gameId, color }
+6. GET  /bot/stream/game/{gameId}               # existing endpoint
+7. POST /bot/game/{gameId}/move/{uci}           # existing endpoint, repeated
+   -- game ends --
+
+8. receive: roundFinished
+9. GET  /api/tournament/{id}/standings          # optional, inspect scores
+   -- repeat 5–9 for each round --
+
+10. receive: tournamentFinished
+11. GET /api/tournament/{id}/standings          # final ranking
+```
