+-- 007_worker_vip_levels_and_invite.sql —— VIP 等级体系与邀请绑定。
+--
+-- 说明：
+-- 1. 等级升级按累计验收通过（accepted）工单数，阈值存 permission_json.upgradeThreshold，后台可配；
+-- 2. 每个打手拥有唯一邀请码，注册时可填邀请码绑定邀请人（inviter_id）；
+-- 3. 存量打手统一归 VIP1，原 regular 等级停用；
+-- 4. 佣金结算暂缓（规则未定），本迁移只落邀请关系，后续按规则补佣金。
+
+-- 1) worker_users 增加邀请字段
+ALTER TABLE worker_users ADD COLUMN IF NOT EXISTS inviter_id BIGINT REFERENCES worker_users(id) ON DELETE SET NULL;
+ALTER TABLE worker_users ADD COLUMN IF NOT EXISTS invite_code TEXT;
+
+-- 2) 存量用户填充唯一邀请码（8 位大写字母数字）
+UPDATE worker_users
+SET invite_code = UPPER(SUBSTRING(MD5(random()::text || id::text) FROM 1 FOR 8))
+WHERE invite_code IS NULL;
+
+ALTER TABLE worker_users ALTER COLUMN invite_code SET NOT NULL;
+CREATE UNIQUE INDEX IF NOT EXISTS idx_worker_users_invite_code ON worker_users(invite_code);
+CREATE INDEX IF NOT EXISTS idx_worker_users_inviter ON worker_users(inviter_id);
+
+-- 3) seed VIP1-5 等级（level_key 唯一，重复执行不覆盖）
+INSERT INTO worker_levels (level_key, name, sort_order, status, permission_json, created_at, updated_at) VALUES
+  ('vip1', 'VIP1', 10, 'active', '{"depositFreeAmount":0,"maxActiveOrders":1,"upgradeThreshold":0}', NOW(), NOW()),
+  ('vip2', 'VIP2', 20, 'active', '{"depositFreeAmount":0,"maxActiveOrders":3,"upgradeThreshold":10}', NOW(), NOW()),

+  ('vip4', 'VIP4', 40, 'active', '{"depositFreeAmount":0,"maxActiveOrders":50,"upgradeThreshold":50}', NOW(), NOW()),
+  ('vip5', 'VIP5', 50, 'active', '{"depositFreeAmount":0,"maxActiveOrders":100,"upgradeThreshold":100}', NOW(), NOW())
+ON CONFLICT (level_key) DO NOTHING;
+
+-- 4) 存量打手统一归 VIP1，原 regular 等级停用
