+P22PROD1-0,P22PROD1执行合同建档与生产化边界冻结,新建执行合同 CSV 并冻结路由分包、差旅与移动审批 E2E、性能审计与小步修复的实现边界，不混入 IM-2/规格书补齐/依赖升级。,refresh CSV 校验通过并明确 P22+PROD-1 为单一聚焦的生产化准备迭代。,python3 /home/shunli/.codex/skills/plan/scripts/validate_issues_csv.py issues/2026-03-12_16-58-44-p22-prod-1-l5-production-hardening.csv,manual,DONE,DONE,DONE,issues/2026-03-12_16-58-44-p22-prod-1-l5-production-hardening.csv|docs/feature-matrix.md|scripts/validate-feature-matrix.py,[],freezes PROD-1 as route splitting plus E2E plus evidence-based performance hardening only
+P22PROD1-1,路由懒加载与构建分包治理,将顶层业务页面切换为 React.lazy + Suspense 并在 Vite 中固定 vendor/manualChunks 分包策略，保持现有 URL 与权限语义不变。,client build 不再出现大包 warning，页面路由切换、刷新与权限守卫行为不回归。,cd client && npm run typecheck && npm run build,manual,DONE,DONE,DONE,client/src/router/index.tsx|client/src/router/lazy/*|client/src/components/common/RoutePageFallback.tsx|client/vite.config.ts,"[""P22PROD1-0""]",keep page modules as named exports and use lightweight lazy wrappers instead of mass default-export refactor
+P22PROD1-2,差旅三部曲Playwright补齐,新增差旅支付与差旅对账 Playwright 规格，覆盖申请审批后支付轨道、mark-paid、发票绑定、reconciliation batch 创建与 finalize 主链路。,travel payment 与 reconciliation 两条主链路可自动化回归，不直接写数据库且页面关键状态可见。,cd client && npm run test:e2e -- tests/e2e/travel-payment-flow.spec.ts && npm run test:e2e -- tests/e2e/travel-reconciliation-flow.spec.ts,manual,DONE,DONE,DONE,client/tests/e2e/travel-payment-flow.spec.ts|client/tests/e2e/travel-reconciliation-flow.spec.ts|client/tests/e2e/helpers/*,"[""P22PROD1-1""]",deterministic seed must go through controlled HTTP APIs or test helpers instead of raw DB writes
+P22PROD1-3,移动审批deep link与离线草稿E2E补齐,新增移动审批 Playwright 规格，覆盖 canonical deep link 移动分流、离线 approve/reject 草稿入队、联网重放与冲突态展示。,移动模式下 workflow canonical link 正确落到 /mobile/approvals，离线草稿入队/重放/冲突均可验证。,cd client && npm run test:e2e -- tests/e2e/mobile-approvals-offline.spec.ts,manual,DONE,DONE,DONE,client/tests/e2e/mobile-approvals-offline.spec.ts|client/tests/e2e/helpers/*|client/playwright.config.ts,"[""P22PROD1-1""]",limit automation to browser offline toggling and do not require real IM container or standalone install mode
+P22PROD1-4,高频查询性能审计与小步修复,针对 workflow tasks、assets q 与 travel reconciliation batches 增加 benchmark 脚本、EXPLAIN ANALYZE 证据链，并仅在收益充分时落地查询重写或常规索引。,三条关键路径都有 before/after 证据且仅保留证据充分的常规索引或查询修复，不引入 PG extension。,cd server && npm run test && ./scripts/benchmark-workflow.sh && ./scripts/benchmark-assets.sh && ./scripts/benchmark-travel-reconciliation.sh,manual,DONE,DONE,DONE,server/src/routes/assets.js|server/src/routes/workflow.js|server/src/services/travelReconciliation.js|server/scripts/benchmark-workflow.sh|server/scripts/benchmark-assets.sh|server/scripts/benchmark-travel-reconciliation.sh|server/prisma/schema.prisma|server/prisma/migrations/*_p22_prod_1_performance_hardening/*,"[""P22PROD1-0""]",assets search stays exact-first then fuzzy-second and any schema change must be justified by >=30 percent measured improvement
+P22PROD1-5,P22PROD1矩阵回归与验收收口,同步 Feature Matrix 与事实源校验器并执行前后端回归，形成 P22+PROD-1 的生产化验收结论。,矩阵推进到 272，新增合同三状态全 DONE，前后端回归与 diff 检查全部通过。,cd client && npm run typecheck && npm run build && npm run test:e2e && cd ../server && npm run test && ./scripts/regression-workflow-actions.sh && ./scripts/regression-all.sh && cd .. && python3 /home/shunli/.codex/skills/plan/scripts/validate_issues_csv.py issues/2026-03-12_16-58-44-p22-prod-1-l5-production-hardening.csv && python3 scripts/validate-feature-matrix.py && git diff --check,manual,DONE,DONE,DONE,issues/2026-03-12_16-58-44-p22-prod-1-l5-production-hardening.csv|docs/feature-matrix.md|scripts/validate-feature-matrix.py,"[""P22PROD1-2"",""P22PROD1-3"",""P22PROD1-4""]",requirements-specification remains out of scope for this iteration
