+## Scenario: Formal Feature-Flag Baseline And Reversible QA Window
+
+### 1. Scope / Trigger
+
+- Trigger: a feature is formally enabled after an earlier short-window rollout, or a QA runner temporarily changes an existing feature flag.
+- Purpose: prevent a new database, stale `.env` or QA cleanup path from silently returning a formal capability to its old disabled state.
+
+### 2. Signatures
+
+- Hard gate: `PAYMENT_BATCH_ENABLED=true` in `deploy/trialrun/.env.example` and the active production env.
+- Database baseline: `payment_batch_v1` is first-created as `force_on/global`; `seed:config` still uses create plus `P2002` preservation and never updates an existing row.
+- Deployment assertion: `smoke-trialrun-runtime.js` requires both the env value and effective `FEATURE_FLAG_KEYS.paymentBatch` result.
+- QA snapshot helper: `node scripts/qa/payment-batch-flag-snapshot.mjs capture|restore --snapshot-file <private-json>`.
+- Mobile entry: `/mobile/payment-batches`; PC remains `/payment-batches`.
+
+### 3. Contracts
+
+- Formal enablement is a three-layer contract: env hard gate, database feature flag and runtime smoke. Changing only one layer is incomplete.
+- A short QA window captures `overrideMode`, `rolloutType`, `departmentIds` and `note` before its first flag write and restores those fields in `finally`; it must work when the caller starts either enabled or disabled.
+- A formal-enable runner keeps `force_on` only after every acceptance step passes. Any failed step restores its caller snapshot, not a hard-coded `force_off`.
+- Snapshot files use mode `0600`, contain configuration only and remain under the ignored QA report directory. Credentials and access tokens never enter the snapshot or output.
+- Mobile links must target the mobile route. Enterprise-messenger routing maps a PC-only payment path back to the mobile workbench, so a PC path is not a valid mobile deep link even when the underlying page is responsive.
+- Mobile and PC payment routes share the same permission guard; adding reachability must not broaden `payment.batch.manage|payment.batch.review|risk.review.manage`.
+
+### 4. Validation & Error Matrix
+
+- Env false or absent -> runtime smoke fails before deployment is accepted.
+- Database flag absent/disabled -> runtime smoke fails with the feature-flag reason; do not hide the failure by changing navigation only.
+- Seed meets an existing flag -> `P2002` is preserved with zero update/upsert calls.
+- QA capture fails -> stop before the temporary window; do not run with an unknown rollback target.
+- QA action or later matrix fails -> restore the caller snapshot and keep the run failed.
+- Snapshot restore version conflicts -> fail visibly; never fall back to `force_off`.
+- Mobile finance entry points at `/payment-batches` -> small-screen routing returns to `/mobile`; treat this as an unreachable entry and use `/mobile/payment-batches`.
+- User lacks payment permission -> both routes remain forbidden even if the feature is enabled.
+
+### 5. Good/Base/Bad Cases
+
+- Good: env true + seed first-create force-on + effective runtime smoke pass; a temporary off/on test restores an original allowlist and note byte-for-byte.
+- Base: a database already contains an operator-managed flag; deployment seed preserves it and runtime smoke reports whether it matches the formal baseline.
+- Bad: change only the DB flag while env remains false, or make the mobile card visible but link it to a path that the mobile shell redirects home.
+- Bad: every QA cleanup writes `force_off`, erasing a formal-on state that existed before the test.
+
+### 6. Tests Required
+
+- Seed unit test asserts first-create `force_on/global` and proves `P2002` performs no update/upsert.
+- Snapshot helper tests cover an original `force_off` allowlist and an original `force_on` global configuration, including note restoration.
+- Deployment contract test asserts the env baseline, runtime-smoke flag assertion and absence of fixed-off cleanup helpers.
+- Mobile Playwright covers zero batches/zero exceptions with the feature enabled, a visible “进入付款” link, successful `/mobile/payment-batches` navigation and no finance card for an unrelated role.
+- Run client typecheck/build, Prisma validate, shell/Node syntax, task/governance/process/sensitive gates and `git diff --check`.
+- Public rollout additionally verifies active env, effective flag reason, finance navigation and eligible candidate count without creating, reviewing or executing a real batch.

+PUT payment_batch_v1 '{"overrideMode":"force_off"}'

+## 7. 付款入口与正式常开防复发
+
+### 7.1 已确认根因
+
+- 当前生产库 `payment_batch_v1` 为版本 1，创建时间等于更新时间，`updated_by` 为空，且没有任何 `FEATURE_FLAG_UPDATED` 审计。
+- 这证明当前库是在初始化时由 seed 首次创建默认 `force_off`，不是 seed 覆盖已有值，也不是 QA runner 或控制台在当前库执行了关闭。
+- 当前运行环境同时为 `PAYMENT_BATCH_ENABLED=false`，因此数据库即使改成 `force_on` 也会被 `env_hard_off` 拦截。
+- 当前唯一 active 财务人员具备 `payment.batch.manage`，但付款入口和已批准候选均因功能门控被隐藏；权限不是根因。
+
+### 7.2 稳定基线
+
+- 试运行正式基线把 `PAYMENT_BATCH_ENABLED` 设为 true，并把 seed 中 `payment_batch_v1` 的首次创建默认值设为全局 `force_on`；seed 继续只创建缺失记录，不更新已有记录。
+- 部署/runtime smoke 明确断言付款批次有效开启，防止换库、换 `.env` 或恢复后再次静默关闭。
+- QA 短窗口保存进入前完整快照并在 finally 恢复该快照；只有明确的正式启用流程在成功时保留 `force_on`，失败才恢复调用前状态。
+
+### 7.3 入口规则
+
+- PC 继续使用现有“付款”导航。
+- 移动财务工作台在付款能力开启时固定显示财务卡片，不再要求先存在批次或异常；卡片进入受同一付款权限保护的 `/mobile/payment-batches`，复用现有响应式付款页，避免企微小屏把 PC 路径重定向回首页。
+- 入口只对真实 finance/finance_mgr 且具备付款权限的人员显示；不向普通员工或仅审批人开放创建能力。
+- 本轮不自动打开创建面板、不自动选择报销、不代替真实财务动作。
