+# API Changes (Not Yet Reflected in `backend/openapi/openapi.json`)
+
+This document lists additive API changes currently implemented in the Go backend.
+
+## Summary
+
+Existing endpoints remain compatible.
+
+Added capabilities:
+
+1. Position board persistence for live/admin ordering.
+2. Stage session control (`start`/`end`) for event flow.
+3. Stage history retrieval.
+4. New state fields (`positionBoards`, `current_stage`, `last_stage`).
+
+## 1) Position Board Endpoint
+
+- Method: `PUT`
+- Path: `/api/admin/positions/:board`
+- Auth: admin bearer token (`Authorization: Bearer <token>`)
+
+### Supported `:board` values
+
+- `preliminary`
+- `final`
+- `prelim_tiebreak`
+- `final_tiebreak`
+
+### Request body
+
+```json
+{
+  "slots": [
+    { "playerId": 12, "groupKey": "A", "position": 1 },
+    { "playerId": 15, "groupKey": "A", "position": 2 },
+    { "playerId": 20, "groupKey": "B", "position": 1 }
+  ]
+}
+```
+
+Fields:
+
+- `playerId` (integer, required)
+- `groupKey` (string, required)
+- `position` (integer > 0, required)
+
+Notes:
+
+- The request replaces all saved slots for the target board.
+- For `preliminary`, `players.group_code` is synchronized from `groupKey`.
+- Special value `UNASSIGNED` maps to empty player group.
+
+### Response
+
+- `200 OK` with full updated admin state payload.
+
+## 2) Stage Session Control Endpoints
+
+### Start stage
+
+- Method: `POST`
+- Path: `/api/admin/stage/start`
+- Auth: admin bearer token
+
+Request body:
+
+```json
+{
+  "phase": "preliminary",
+  "group": "A",
+  "round": 2
+}
+```
+
+Rules:
+
+- `phase` must be one of:
+  - `preliminary`
+  - `prelim_tiebreak`
+  - `final`
+  - `final_tiebreak`
+- `group` validation depends on phase:
+  - `preliminary`: group code string (or `UNASSIGNED`)
+  - `final`: `"1"` or `"2"`
+  - tie-break phases: positive numeric string
+- `round` normalization:
+  - `preliminary`: `1..3`
+  - `final`: `1..2`
+  - tie-break phases: always `1`
+- If another stage is active (started, not ended), API returns `409`.
+
+Response:
+
+- `200 OK` with full updated admin state payload.
+
+### End stage
+
+- Method: `POST`
+- Path: `/api/admin/stage/end`
+- Auth: admin bearer token
+
+Rules:
+
+- Ends the currently active stage by setting `ended_at`.
+- If no active stage exists, API returns `400`.
+
+Response:
+
+- `200 OK` with full updated admin state payload.
+
+## 3) Stage History Endpoint
+
+- Method: `GET`
+- Path: `/api/admin/stage/history`
+- Auth: admin bearer token
+
+Response:
+
+```json
+{
+  "items": [
+    {
+      "id": 1,
+      "phase": "preliminary",
+      "group": "A",
+      "round": 2,
+      "startedAt": "2026-04-30T08:27:13Z",
+      "endedAt": "2026-04-30T08:28:01Z"
+    }
+  ]
+}
+```
+
+## 4) New State Fields
+
+Both endpoints now include these fields:
+
+- `GET /api/state`
+- `GET /api/admin/state`
+
+```json
+{
+  "positionBoards": {
+    "preliminary": {
+      "12": { "groupKey": "A", "position": 1 }
+    },
+    "final": {
+      "12": { "groupKey": "1", "position": 3 }
+    },
+    "prelim_tiebreak": {},
+    "final_tiebreak": {}
+  },
+  "current_stage": {
+    "id": 7,
+    "phase": "preliminary",
+    "group": "A",
+    "round": 2,
+    "startedAt": "2026-04-30T09:00:00Z"
+  },
+  "last_stage": {
+    "id": 6,
+    "phase": "final",
+    "group": "1",
+    "round": 1,
+    "startedAt": "2026-04-30T08:45:00Z",
+    "endedAt": "2026-04-30T08:55:00Z"
+  }
+}
+```
+
+Notes:
+
+- `positionBoards` keys are player IDs as strings.
+- `current_stage` is `null` when no stage is active.
+- `last_stage` is `null` when no stage session has ever started.
+- `last_stage` is the most recently started session (ended or still active).
+
+## Compatibility Impact
+
+- Additive only; existing consumers remain functional.
+- Consumers can ignore unknown fields safely.
+- Consumers needing control/monitoring can use new stage endpoints and fields.
