+# docgov-pi-narrative 收口：修复后复测升 done
+
+## 用户目标与授权
+
+- 用户目标：审查并调整既有方案，推进 FEATURE-MATRIX `docgov-pi-narrative` 从 `partial` 结束为 `done`。
+- 授权来源：用户确认「docgov-pi-narrative 收口计划（复测后升 done）」并指示实施。
+- 交付终点：修复后真实 PI 复测 + 测试报告 + MATRIX 升 done + 合入 local `dev`；不 push；不放量 flag。
+- 禁止项：不默认开启仓库/compose `PI_CHANGE_REPORT_NARRATIVE`；不改 gap-matrix / `production_ready`；不晋升 test/main。
+
+## 范围与非目标
+
+- 允许：补强 `TestPiChangeReportNarrator_LiveMiniMax`（含 hunks + flag-on Resolve）；sysadmin reason；MATRIX/CURRENT/pu7/short-term/test-report。
+- 非目标：dev 常驻开启叙事 flag；Playwright flag-on 全链路；触碰 Cline partial-deferred 总控实现。
+
+## 相关问题与经验
+
+- 开工检索：docgov / PI narrative / change_report_narrative / `--no-tools`。
+- ISSUES / lessons：无直接命中 PI 叙事；沿用 content-hash 投影经验（证据与状态分轨）。
+- 历史缺口（2026-09-20）：计数-only 输入、prompt-only no-tool → 已修；本轮补修复后真实链路复测。
+
+## 步骤与验收
+
+1. [x] 建场并认领 mutex `docgov`
+2. [ ] 补强 live 测试输入与 flag-on Resolve 断言
+3. [ ] 真实 PI 复测 + 前端分区 + vet/short/arch
+4. [ ] MATRIX → done；CURRENT/pu7/sysadmin 同步
+5. [ ] 测试报告归档；validate + queue enqueue；五态收口
+
+## 验证与证据
+
+| 范围 / 被测 SHA | 命令与环境 | 预期 | 实际 / 判定 | 证据 / 脱敏说明 |
+|---|---|---|---|---|
+| live PI（进程 env flag） | `RUN_PI_E2E=1 … TestPiChangeReportNarrator_LiveMiniMax` | PASS；digest 原样；含截断差异 | pending | 报告 assets |
+| 前端分区 | `overlayMode.test.ts` | PASS | pending | |
+| 门禁 | `go vet` / `go test -short` / `arch-check --mode block` | 全绿 | pending | |
+
+## 收口与交接
+
+- 剩余：见步骤未勾项。
+- remote_sync=not_requested。
+- cleanup 交独立维护者。
