# Channel Management (Admin)

## 1. Purpose

Documents the **Channel Management** page (`/admin/channel`): summary cards, list scope, button permissions, bet-record dialogs, and APIs. For commission calculation and agent tree split, see [commission-share-guide.md](./commission-share-guide.md).

---

## 2. Summary cards

| Card | Description |
|------|-------------|
| Total channels | Count in **readable scope** |
| Enabled | `status = 1` |
| Pending dividend (count) | `carryover_balance > 0` |
| Pending dividend (amount) | Sum of those balances |
| Paid dividend | Sum of paid `agent_commission_record` in scope; clickable dialog requires `viewDividendRecords` |

List filters: **All / With balance / No balance / Enabled only / Disabled only** (UI search only).

---

## 3. Read scope

`AdminChannelScopeService` applies to list and stats:

**Bound channel wins** (only those channels) if `admin.channel_id` > 0 and/or any role group has `channel_id` — even with `viewAllChannels`.

**Global read** only when: super admin, **or** no channel binding on account and all groups **and** `viewAllChannels`.

**Write** (add/edit/delete/manual settle DB) stays on **writable** channels only; `viewAllChannels` does not expand write scope.

---

## 4. Actions & permissions

| Node | Label | Behavior |
|------|-------|----------|
| `channel/viewAllChannels` | View all channels | Global read scope |
| `channel/viewDividendRecords` | Paid dividend records | Top card + dialog |
| `channel/viewDirectBetRecords` | Direct bet records | Direct bet column click |
| `channel/viewSettlementBetRecords` | Settlement-scope bets | Row action |
| `channel/manualSettle` | Manual settle | Preview + submit (readable channel) |
| `channel/batchSettlePending` | Batch settle | **Super admin only** |

Re-login after role changes to refresh `authNode`.

---

## 5. Manual settlement

- `GET /admin/channel/manualSettlePreview?id=`
- `POST /admin/channel/manualSettle`
- Super admin **or** `channel/manualSettle` with channel in read scope
- Same payout flow as super-admin settle (`ChannelSettlementService::settleBySuperAdmin`)

---

## 6. Bet record dialogs

| Entry | API | Data |
|-------|-----|------|
| Direct bet amount | `directBetRecordList` | All play records for channel |
| View settlement bets | `settlementBetRecordList` | `status = 2` only |

**Filters (GET):** `period_no`, `user_keyword`, `result_number`, `pick_number`, `win_hit` (`won`/`lost`/`pending`), `page`, `limit`.

**Columns:** period, player, channel, picks, winning number, win status, bet amount, win amount.

**Mobile:** ~92% width, scrollable body, 3 summary cards per row, horizontal table scroll.
