CreateSubscription/applySubscription 加 source 参数(兑换路径传 "code" 零行为变化);新导出 GrantPaidSubscriptionTx(ctx, tx, ...) 供 pay 侧在 调用方事务内以 source='pay' 复用同一段叠加语义(同 plan 活跃订阅原地 延长,否则新建行),写 pay_grant 审计。 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013nMthbVEmQquxBRKb9Fj8u
