…e 与 bundle 签名 - build 读工程根的 tinyui.config.json（name / publicKey / pages），页面模块名改为 <pkg>/<相对路径>， manifest 加 name / publicKey / version / createdAt / engine / protocol / hashes；engine 读字节码文件头， protocol 经 tinyui-core/protocol 子路径导出取得（core 新增该入口，只含常量） - keys generate：P-256 密钥对，私钥 PKCS#8 PEM、公钥 X9.63 未压缩点 base64 - bundle：写定 <pkg>/<rv>/<version>/manifest.json 后对文件原始字节签名（DER base64）， 签名与 version / rollout 写 current.json；私钥与 publicKey 不配对、字节码与 hashes 不符、 --js-only 产物均拒绝 - sample 包名 sample（配置与演示密钥进仓），sample/shared 与 Android host 测试的模块名随之改为 sample/todos Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Reviewer's Guide该 PR 完成热下发 M1 的 CLI 产包链路：build 从 tinyui.config.json 读取包身份并生成包含引擎、协议和字节码哈希的 manifest，keys 生成 P-256 发布密钥，bundle 校验产物后按约定目录复制并对原始 manifest 字节签名；同时将宿主、sample、core 导出和文档迁移到新的包名前缀模块名。 Sequence diagram for creating and verifying a signed TinyUI bundlesequenceDiagram

摘要
本次改动为 CLI 增加了配置加载、构建 manifest 扩展、密钥生成和签名 bundle 产出，并将页面模块名切换为包名前缀形式。签名及哈希校验主流程基本完整，但 bundle 对版本目录的路径和已有目录处理不安全。该问题可导致构建/发布过程删除预期目录之外的文件，也破坏了版本目录不可变的约定。

## Individual Comments
### Comment 1
<location path="packages/cli/src/bundle.ts" line_range="53" />
<code_context>
+ if (!manifest.engine) throw new Error(`${dist} has no bytecode (built with --js-only); a package needs .bin files`);
+
+ const dir = join(out, manifest.name, options.runtimeVersion);
+ const versionDir = join(dir, manifest.version);
+ await rm(versionDir, { recursive: true, force: true });
+ for (const [module, path] of Object.entries(manifest.files)) {
</code_context>
<issue_to_address>
**🚨 issue (security):** `manifest.version` is joined directly into the output path without validating that it is a single safe path segment. A build invoked with `--version ../outside` causes `bundle` to write its manifest and bytecode outside `<out>/<pkg>/<runtimeVersion>`, allowing arbitrary output-path escape.
**Triggers:** When `tinyui build --version` receives a value containing `..` or path separators.
**Suggested fix:** Validate versions against a safe segment pattern such as `^[A-Za-z0-9._-]+$`, or resolve the path and verify it remains below `dir` before writing.
```suggestion
if (!RUNTIME_VERSION.test(manifest.version)) throw new Error(`manifest version must match ${RUNTIME_VERSION}, got "${manifest.version}"`);
const versionDir = join(dir, manifest.version);
```
</issue_to_address>
### Comment 2

+ const dir = join(out, manifest.name, options.runtimeVersion);
+ const versionDir = join(dir, manifest.version);
+ await rm(versionDir, { recursive: true, force: true });
+ for (const [module, path] of Object.entries(manifest.files)) {
+ const source = join(dist, path + ".bin");
</code_context>
<issue_to_address>
**issue (bug_risk):** `bundle` deletes the existing immutable version directory before validating every bytecode hash and before writing the replacement. Re-running a bundle for an existing version with a tampered or otherwise invalid `.bin` removes the previously valid published artifact and then exits with an error.
**Triggers:** When the same version is bundled again and any listed bytecode file fails validation or a later write fails.
**Suggested fix:** Validate and stage the complete bundle in a temporary directory first, then atomically rename it into place; never remove an existing version directory during a failed attempt.
</issue_to_address>
### Comment 3
<location path="packages/cli/src/config.ts" line_range="36-37" />
<code_context>
+ if (typeof raw !== "object" || raw === null) throw new Error(`${file}: expected an object`);
+ const { name, publicKey, pages } = raw as Record<string, unknown>;
+ if (typeof name !== "string" || !NAME.test(name)) throw new Error(`${file}: "name" must match ${NAME}`);
+ if (typeof publicKey !== "string" || !isPublicKey(publicKey)) {
+ throw new Error(`${file}: "publicKey" must be a P-256 uncompressed point in base64 (65 bytes, 04-prefixed); tinyui keys generate prints one`);
+ }
+ if (pages !== undefined && (typeof pages !== "string" || pages === "")) throw new Error(`${file}: "pages" must be a directory path`);
</code_context>
<issue_to_address>
**issue (bug_risk):** `isPublicKey` checks only base64 canonicality, length, and the `04` prefix; it does not verify that the coordinates form a valid point on the P-256 curve. An invalid 65-byte value is accepted by `tinyui build` and written into the manifest even though it is not a usable P-256 public key, so signing/bundle or downstream verification fails later instead of configuration loading rejecting it.
**Triggers:** When `tinyui.config.json` contains a 65-byte `04`-prefixed value with coordinates that are not on P-256.
**Suggested fix:** Import the raw point with Node's P-256 key parser, or otherwise perform a curve-point validity check inside `isPublicKey` before accepting the configuration.
</issue_to_address>
### Comment 4
<location path="packages/cli/src/bundle.ts" line_range="55-60" />

+ const dir = join(out, manifest.name, options.runtimeVersion);

+ const target = join(versionDir, path + ".bin");
+ await mkdir(dirname(target), { recursive: true });
+ await copyFile(source, target);
</code_context>
<issue_to_address>
**🚨 issue (security):** `manifest.files[module]` is treated as a filesystem-relative path without a containment check. A modified build manifest containing `../` segments makes `bundle` read arbitrary `.bin` files outside `dist` and copy them into the signed OTA output.
**Triggers:** When a build directory contains a crafted or corrupted `manifest.json` whose `files` value escapes `dist`.
**Suggested fix:** Require every manifest file path to be relative, reject absolute paths and `..` segments, and verify the resolved source remains below `dist` before reading or copying.
```suggestion
for (const [module, path] of Object.entries(manifest.files)) {
if (path.startsWith("/") || path.startsWith("\\") || /^[A-Za-z]:[\\/]/.test(path) || path.split(/[\\/]/).includes("..")) {
throw new Error(`invalid manifest file path: ${path}`);
}
const source = resolve(dist, path + ".bin");
if (!dist.endsWith("/") && !dist.endsWith("\\") && !source.startsWith(dist + "/") && !source.startsWith(dist + "\\")) {
throw new Error(`${source} is outside ${dist}`);
}
const expected = manifest.hashes[module];
const actual = createHash("sha256").update(await readFile(source)).digest("hex");
if (actual !== expected) throw new Error(`${source} does not match manifest.hashes (${actual} vs ${expected}); rerun tinyui build`);
const target = join(versionDir, path + ".bin");

</issue_to_address>Sourcery assessment
Needs a human reviewer. 6 findings to address first, and this adds the signing-key trust boundary for hot-update bundles: a bad key/public-key relationship or signature implementation could either block updates or allow an incorrectly trusted package to reach every client that accepts it. Reverting the CLI cannot undo bundles already published or code already installed, and the trust decision is fixed for all packages from the moment it ships.
Blocking findings: packages/cli/src/bundle.ts:53, packages/cli/src/bundle.ts:54, packages/cli/src/config.ts:37, packages/cli/src/bundle.ts:60, packages/cli/test/fixtures/keys/signing-key.pem:5, and 1 more

摘要
本次增量在 bundle 中补充了 manifest 包名和公钥格式校验，并复用了配置层的包名校验函数。此前仅比较私钥导出公钥而未限制曲线类型的问题已通过 isPublicKey 校验修复，新增测试覆盖了 P-384 公钥场景。未发现本次增量引入的其他实际问题。

摘要
本次增量将 bundle 的版本目录和指针文件改为通过临时文件/目录后重命名写入，并加强了 manifest 表结构及 pages 路径校验。主要风险在于版本目录的“清理不完整产物”逻辑没有并发保护，两个进程同时打包时可能破坏版本不可变性；此外 pages 路径校验会误拒绝部分实际位于项目根目录内的合法目录。
