摘要
本次改动将 pull 的信任锚迁移到宿主仓内已有的内置包，并在更新库中为不兼容的内置包增加了降级事件和继续拉取更新的路径。PackageCheck 也补充了对运行时、协议、tinyui 版本及宿主依赖的检查。主要风险在首次拉取时遇到灰度指针：当前实现会成功返回但不生成任何内置包目录。

Hey - I've found 1 issue
Prompt for AI Agents
Please address the comments from this code review:
## Individual Comments
### Comment 1
<location path="packages/cli/src/pull.ts" line_range="74" />
<code_context>
+ // a version still rolling out is not yet what every user runs: it must not become the floor of every new install
+ const rollout = typeof pointer.rollout === "number" ? pointer.rollout : 100;
+ if (rollout < 100) return keep(`${options.channel} is at ${version} rolling out to ${rollout}%`);
+ if (current?.version === version) return keep(`already ${version}`);
const manifestBytes = await get(`${version}/manifest.json`);
</code_context>
<issue_to_address>
**issue (bug_risk):** `pull` returns `changed: false` solely because the pointer version equals the embedded manifest version, without checking that the existing package targets `options.hostVersion`. When the same package version is published for a new host version, or `--out` contains a locally built manifest without `hostVersion`, the command keeps bytes that are not validated for the current host.
**Triggers:** When the host version changes but the channel points to the same package version.
**Suggested fix:** Require `current?.hostVersion === options.hostVersion` before returning `already`; otherwise fetch and validate the manifest for the requested host version.
```suggestion
if (current?.version === version && current?.hostVersion === options.hostVersion) return keep(`already ${version}`);
```
</issue_to_address>Sourcery assessment
Needs a human reviewer. 1 finding to address first, and this changes the OTA trust and package-selection paths, including signing-key rotation, embedded-package floors, and how incompatible or rolled-back packages are handled. A mistake could make an update run incompatible code or accept the wrong package and cause a broad page outage; reverting the code does not undo packages already embedded or installed, though a newly published version or app release can repair it.
Blocking findings: packages/cli/src/pull.ts:74

`current?.version === version` returns “already” only when `current.hostVersion`
also matches `options.hostVersion. Otherwise, let the existing host-version
