供应链演练与回滚流程治理（演练-SLA-手册）最佳实践

实现示例type Playbook = { steps: string[]; slaMin: number } type Incident = { id: string; start: number; mitigated?: number } function validPlaybook(p: Playbook): boolean { return p.steps.length >= 3 && p.slaMin > 0 } function withinSla(inc: Incident, p: Playbook): boolean { return !!inc.mitigated && (inc.mitigated - inc.start) <= p.slaMin * 60 * 1000 } function evaluate(p: Playbook, inc: Incident): { ok: boolean; errors: string[] } { const errors: string[] = []; if (!validPlaybook(p)) errors.push('playbook'); if (!withinSla(inc, p)) errors.push('sla'); return { ok: errors.length === 0, errors } } 审计与运行治理审计演练流程与SLA达标情况；未达标需复盘与改进。回滚操作需审批与记录。
