Commission Share Guide

1. Purpose

This document describes the end-to-end flow channel commission → agent tree split → admin wallet credit, so operations, finance, and engineering share the same configuration and settlement rules.

---

2. Overall Structure (Two Layers + Tree)

Commission is calculated in two steps:

A. Layer 1: Channel settlement (platform → channel)

• Compute channel total commission from channel.agent_mode:
  • turnover: base = sum of settled bet amounts; commission = total bet × turnover_share_rate
  • affiliate: base = platform profit after cost deduction; commission = base × ladder share rate
• Data scope: bet_order.status = 2 (settled), period = last settlement end ~ current settlement time
• Output: agent_settlement_period snapshot

B. Layer 2: Agent tree split (channel total → each admin’s net amount)

• Do not configure flat channel-wide shares on the channel page (channel_admin_share is deprecated in UI; table may remain for history)
• Maintain the agent tree in Administrator Management (/admin/auth/admin):
  • parent_admin_id: parent agent (empty for top-level)
  • commission_share_rate: percentage taken from parent’s commission for this period (sub-agents only)
• At settlement, AdminCommissionDistributionService splits recursively:
  1. Channel total commission goes to top-level agent(s) (parent_admin_id is null)
  2. Each agent allocates to direct children by commission_share_rate from their own received amount
  3. Parent keeps = received amount − sum allocated to children

Example (parent receives 3000 this period):

Sub-agent	Rate	Amount
Sub-agent A	20%	600
Sub-agent B	40%	1200
Parent	—	1200 (3000 − 600 − 1200)

If a sub-agent has further downline, the same rules apply on their received amount.

3. Configuration & Permissions

Capability	Entry	Notes
Channel commission params	/admin/channel	agent_mode, turnover/affiliate rates, settlement cycle, etc.
Agent tree & share rates	/admin/auth/admin	Tree list; parent agent, share rate, channel
Channel filter	Admin list common search	Super admin can filter by channel
Visibility	Admin list	Non–super admin sees self + all downline only
Settlement	/admin/channel manual / cron	Super admin only; credits admin_wallet on settle

3.1 Sub-agent share validation

• Under the same parent_admin_id, enabled sub-agents’ commission_share_rate must not exceed 100% in total
• Form shows remaining allocatable rate when creating/editing sub-agents
• If total is 100%, parent keeps no commission at this level
• Top-level agents (no parent) do not set commission_share_rate

3.2 Role groups

• admin_group is for menu/data permissions only
• Not used in amount calculation

---

4. Settlement Flow

1. Super admin triggers channel settlement (manual or ChannelAutoSettleTicker)
2. ChannelSettlementService::buildSettlePayload aggregates bets and computes channel total commission
3. AdminCommissionDistributionService::distributeChannelCommission splits by agent tree
4. In one transaction:
   • Insert agent_settlement_period (status = 2 completed)
   • Insert agent_commission_record per admin with amount > 0 (status = 1 paid)
   • AdminWalletService::creditCommission → admin_wallet + admin_wallet_record (biz_type = commission_income)
5. Reset channel.carryover_balance to 0 (settle-and-pay; no channel pending pool)

Prerequisite: at least one top-level agent for the channel (channel_id match, parent_admin_id empty); otherwise settlement fails.

---

5. Recommended wording (operations / stakeholders)

1. Channel commission: computed from settled bets for the period (not from deposit volume).
2. Distribution: total commission enters the channel top agent, then splits down by parent/child and share rates in Administrator Management; parent keeps the remainder after paying children.
3. Role groups: permissions only, not money.
4. Traceability: each agent_commission_record links to agent_settlement_period; wallet commission_income traces back to commission records.

6. Core fields

Table / field	Role
channel.agent_mode / turnover_share_rate / affiliate_*	Channel commission calculation
admin.parent_admin_id	Parent agent
admin.channel_id	Channel
admin.commission_share_rate	Share from parent (%); null for top-level
agent_settlement_period	Settlement period snapshot
agent_commission_record	Paid commission per admin
admin_wallet / admin_wallet_record	Admin wallet & ledger

Legacy channel_admin_share: flat 100% split (2026-04-18); tree split since 2026-05-29. Do not configure via this table.
