+## Performance
+
+- **Duration:** 约 12 分钟
+- **Completed:** 2026-10-21
+- **Tasks:** 2（Task 0 汇报关卡已由用户「可以执行」闭环，不在本次执行内重复）
+- **Files:** 新增 2、修改 3、移动 1（旧路径删除）
+
+## 任务执行结果
+
+| Task | 内容 | 结果 |
+| ---- | ---- | ---- |
+| Task 1 | `removeReplayDecorators` / `replayDecoratorPlugin` + `build-game` 双端注入 + 插件测试移动并扩展 | 完成，11/11 用例通过 |
+| Task 2 | content 清单过滤 + `build-resource` 行为测试 + 本 SUMMARY | 完成，9/9 用例通过与全部门禁通过 |
+
+## What Was Built
+
+### 录像装饰器删除插件（`script/build-plugin.ts`）
+
+- 新增不导出常量：`REPLAY_DECORATORS`（`['shouldReplay', 'ignoreReplay']`）、`SCRIPT_EXTENSIONS`（`['.ts', '.tsx']`）、`NODE_MODULES_SEGMENT`（`/[/\\]node_modules[/\\]/`）。
+- `removeReplayDecorators(code, fileName)`：用 `ts.createSourceFile` 建 AST，以显式栈遍历全部节点；对 `ts.canHaveDecorators(node)` 的节点取 `ts.getDecorators(node)`，仅当装饰器表达式是目标标识符或「callee 为目标标识符的调用表达式」时记录 `[getStart, getEnd]`，按起点降序切片删除；无命中时原样返回输入文本。
+- `replayDecoratorPlugin()`：`name: 'mota-replay-decorator'`、`enforce: 'pre'`、`apply: 'build'`；`transform` 先剥离 `?` 查询串，命中 `node_modules` 或非 `.ts` / `.tsx` 返回 `null`，代码未变化也返回 `null`。
+- 既有 `dataIsolationPlugin` / `SPECIFIER_BANS` / `PATH_BANS` / `findBan` 行为与注释一字未动。
+
+### 双端注入（`script/build-game.ts`）
+
+- 导入改为 `{ dataIsolationPlugin, replayDecoratorPlugin }`。
+- `buildClient`：`plugins: [replayDecoratorPlugin(), legacy({ ... })]`（新插件在 `legacy` 之前）。
+- `buildData`：`plugins: [dataIsolationPlugin(), replayDecoratorPlugin()]`（隔离插件保持首位）。
+- 构建顺序（准备 → 渲染端 → 数据端 → content → LICENSE）、产物落点与其余配置均未变。
+
+### content 清单过滤（`script/build-resource.ts`）
+
+- 新增不导出常量 `LIST_FILE_NAME = '.list.jsonc'`、`DEFAULTS_DIRECTORY = 'defaults'`。
+- 新增内部函数：`readListNames`（读文件 → `minifyJSONC` 去注释 → `JSON.parse`）、`collectListedNames`（递归收集全部字符串值）、`isListedFile`（完整文件名或去扩展名主文件名的精确匹配）。
+- `processDirectory` 增加第五个参数 `isRoot = false`：
+  - `buildContent` 的根调用传 `true`，根目录**永不**按清单取舍（即使将来出现根 `.list.jsonc`）；
+  - `defaults/` 通过 `DEFAULTS_DIRECTORY` 显式豁免，全量输出并压缩；
+  - 其余子目录若存在 `.list.jsonc`，只保留被引用文件，未引用文件既不拷贝也不计入统计；
+  - `.list.jsonc` 自身先于过滤判断，始终走 `.jsonc` 压缩分支；
+  - 无清单的子文件夹与递归子目录保持全量。
+- `minifyJSONC` / `buildContent` / 接口名称与签名、字体分支与告警文案均未改；jsonc 仍只剥离整行 `//` 注释（含系统标记行），不改解析与序列化方式，不分块、不 zip。
+
+### 测试（`script/__test__/`）
+
+- `script/__test__/build-plugin.test.ts`：由 `script/build-plugin.test.ts` 移动而来（导入改 `../build-plugin`，旧路径已删除），保留既有 `dataIsolationPlugin` 四个用例；新增纯函数用例（删 `@shouldReplay` / `@ignoreReplay`、参数含双引号与嵌套括号、字符串不误删、注释不误删）与插件跳过用例，以及**对照式双装饰器**真实 `vite.build()`：同一 fixture 内本地定义且不导出 `shouldReplay` / `ignoreReplay` 工厂，导出一个类、两个方法分别带一种装饰器并各返回 `mota_replay_probe` / `mota_ignore_probe`。对照组（`plugins: []`）产物含两个工厂名、两个唯一字面量与两个方法名；实验组不含 `shouldReplay` / `ignoreReplay`，但两个唯一字面量与两个方法名仍在。
+- `script/__test__/build-resource.test.ts`：9 个 fixture 行为用例——根 jsonc 压缩、根目录存在 `.list.jsonc` 仍全量、`defaults/` 存在 `.list.jsonc` 仍全量、maps 清单（原文带 `//` 注释）保留/剔除、texture 对象清单 + 完整文件名按字节保留、font 清单、无清单子文件夹全量、`item.ts` 原样、统计值一致。
+- 每个 `it` 前均有一行中文说明注释（AGENTS.md）。
+
+## Files Created/Modified
+
+- `script/build-plugin.ts`（修改）— 新增录像装饰器删除纯函数与构建插件
+- `script/build-game.ts`（修改）— 双端注入新插件
+- `script/build-resource.ts`（修改）— content 清单过滤
+- `script/__test__/build-plugin.test.ts`（新增；源 `script/build-plugin.test.ts` 已删除）
+- `script/__test__/build-resource.test.ts`（新增）
+- `.planning/phases/09-minimum-browser-runnable/09-22-SUMMARY.md`（本文件）
+
+**未改动（已核对）：** `script/build-lib.ts`、`package.json`、`index.html`、`dev.md`、`src/**`、`public/**`、`packages-user/**`、`packages/**`、`vite.config.ts`、`pnpm-lock.yaml`、`script/dev.ts`、`script/check-data-circular.test.ts`；未手动删除任何 import。
+
+## 命名获批情形
+
+- OI-1：`removeReplayDecorators` / `replayDecoratorPlugin` / `name: 'mota-replay-decorator'`，以及内部常量 `REPLAY_DECORATORS` / `SCRIPT_EXTENSIONS` / `NODE_MODULES_SEGMENT`。
+- OI-2：`LIST_FILE_NAME` / `DEFAULTS_DIRECTORY` / `readListNames` / `collectListedNames` / `isListedFile`，以及 `processDirectory` 的 `isRoot` 参数。
+- OI-3：`script/__test__/build-plugin.test.ts`（移动）与 `script/__test__/build-resource.test.ts`（新增）。
+- 均按计划提议命名采用（Task 0 已报备并由用户批准执行）。
+
+## Gates Run
+
+| 门禁 | 命令 / 内容 | 结果 |
+| ---- | ----------- | ---- |
+| 插件单测 | `cmd /c "pnpm exec vitest run script/__test__/build-plugin.test.ts"` | **PASS**（11/11） |
+| content 单测 | `cmd /c "pnpm exec vitest run script/__test__/build-resource.test.ts"` | **PASS**（9/9） |
+| 合并重跑 | 两个测试文件同时运行 | **PASS**（20/20） |
+| 插件结构门禁 | 计划 Task 1 `<automated>`（AST 标记、`enforce` / `apply`、导出形态、`build-game` 按函数切片、测试位置与正负向断言） | **PASS**（`OK replay plugin: AST strip + dual-sided wiring`） |
+| 插件注释基线门禁 | 与 `gsd-09-22-jsdoc-baseline.json` 比对 | **PASS**（`build-plugin.ts` 既有注释 9 行唯一值全部保留） |
+| content 结构门禁 | 计划 Task 2 `<automated>`（值标记、导出与 `chars: string`、基线注释零丢失、SUMMARY 关键字与基线 SHA） | **PASS** |
+| 真实清单覆盖率 | 5 个清单目录内现存素材全部被清单命中 | **PASS** |
+| eslint | `cmd /c "pnpm exec eslint <5 个改动文件>"` | **PASS**（零报告） |
+
+### 注释基线
+
+- 文件：`gsd-09-22-jsdoc-baseline.json`（由 Task 0 写入仓库外 `os.tmpdir()`，本次执行复用、未覆盖）。
+- 捕获时 `head`：`539c6516720b4aa9f6a0bbbf912ad447f95fc85c`。
+- `script/build-plugin.ts` 与 `script/build-resource.ts` 的既有注释行均与基线逐行一致（去重后分别为 9 行与 24 行），门禁与 git 提交无关、可重复执行。
+
+## Open Items 处置
+
+- OI-1 / OI-2 / OI-3：按计划提议命名采用，未改名。
+- 已知边界见下节，均不在本计划范围。
+
+## Known Boundaries
+
+- **未端到端运行全量 `build:game`：** 渲染端仍有用户 WIP 的 stale import（`src/client/initialize.ts`、`src/client/plugin/shop/shop.tsx`，09-21 已记录）。本次验证只覆盖两个测试文件、结构门禁、注释基线、真实清单覆盖率与 eslint；**不得**表述为「全量构建已通过」。
+- **生产构建不再有录像安全检查：** `@shouldReplay` / `@ignoreReplay` 应用在构建期被删除，运行期不再产生对应的录像收集信息，属用户裁定与 D-96 的预期结果。
+- **`index.html` 仍引用 `/styles.css`：** 本计划不产出、不改该文件（09-21 已记录）。
+- **`animation` / `audio` / `font` 当前无对应素材：** 其清单过滤规则仅由测试覆盖，不影响现有产物。
+- **估算未校准：** 计划 `estimate.tokens=46000` 是 `confidence: low` 的原始估算，尚无历史执行样本，本次 `actuals.tokens≈7900` 为按实际改动字符数（chars/4）测得，二者差异不构成校准结论（`uncalibrated`）。
+
+## Deviations from Plan
+
+无功能性偏差。执行细节说明：
+
+1. **换行符：** 3 个脚本经 `prettier --write` 保持仓库既有 CRLF；2 个新测试文件同样以 `.prettierrc` 的 `endOfLine: crlf` 格式化；本 SUMMARY 沿用 `.planning` 既有的 LF。
+2. **测试辅助函数：** 插件测试把探测构建收敛为一个接收 `{ root, entry, plugins }` 的辅助函数，以便对照组写出字面量 `plugins: []`（结构门禁要求的对照构建），行为与计划一致。
+
+## Issues Encountered
+
+无。两套测试首轮即通过。
+
+## User Setup Required
+
+None。
+
+## Commits
+
+**未提交任何内容（`git add` / `git commit` 均未执行，按本次执行指令保留在工作树）。** `actuals.commits` 因此记录为 0。
