摘要
本次改动新增了 tinyui pull，从公开投递端拉取并验签、校验哈希后生成内置包，同时为 Updates 增加了指针回退到内置包的结果与事件。Updates 的回退判断和状态清理流程与文档目标基本一致。主要风险在于 pull 的输出目录替换不是原子操作，提交阶段失败会直接丢失原有内置包。

Hey - I've found 2 issues

Please address the comments from this code review:
## Individual Comments
### Comment 1
<location path="packages/cli/src/pull.ts" line_range="81-83" />
<code_context>
+ await mkdir(dirname(join(staging, path)), { recursive: true });
+ await writeFile(join(staging, path), bytes);
+ }
+ await rm(out, { recursive: true, force: true });
+ await mkdir(dirname(out), { recursive: true });
+ await rename(staging, out);
+ return { version, files: [...files.keys()].sort() };
+}
</code_context>
<issue_to_address>
**issue (bug_risk):** The existing output directory is deleted before `rename(staging, out)` completes, so a failed rename or process interruption leaves `--out` missing instead of preserving the previous complete package.
**Triggers:** When the final rename fails or the process is interrupted after `rm(out)` and before `rename(staging, out)`.
**Suggested fix:** Use an atomic replacement strategy supported by the target filesystem, or retain the old directory until the staged directory has been successfully swapped into place.
</issue_to_address>
### Comment 2
<location path="packages/cli/src/pull.ts" line_range="75-76" />
<code_context>
+
+ // assembled beside the target and swapped in, so a failed write never leaves half a package
+ const out = resolve(options.out);
+ const staging = `${out}.pulling`;
+ await rm(staging, { recursive: true, force: true });
+ for (const [path, bytes] of files) {
+ await mkdir(dirname(join(staging, path)), { recursive: true });
</code_context>
<issue_to_address>
**issue (bug_risk):** All concurrent `pull` calls for the same or different outputs sharing the same `<out>.pulling` path delete and write the same staging directory, so one call can remove files while another is writing and the final output can be incomplete or belong to the other call.
**Triggers:** When two `pull` operations run concurrently with the same `--out` (or with output paths whose `.pulling` paths collide).
**Suggested fix:** Use a unique staging directory per invocation and atomically publish only that invocation's completed directory; optionally serialize replacement of the same output.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 2 findings to address first, and if the pointer comparison or embedded package selection is wrong, an installed update can be deleted and the app will run a different UI from the next launch; an updated pointer can usually repair this by downloading the package again. A mistakenly pulled embedded package cannot be reverted remotely and would require shipping a new app version, so the impact outlives a code revert but remains bounded.
Blocking findings: packages/cli/src/pull.ts:83, packages/cli/src/pull.ts:76

In `@updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt`:
- Around line 258-265: Update the revert flow around `installed` and
`saveState()`: set `installed` to null, and if `saveState()` throws
`IOException`, restore `installed` to `drop` before returning the storage
failure. After a successful save, treat deletion of the dropped directory as
best-effort rather than returning a storage failure; startup cleanup handles
directories absent from saved state.

Summary by CodeRabbit
tinyui pullto download and verify the current production package for embedding. It replaces the output directory only after validation succeeds and reports the package version and file count.Revertedwhen an installed package is removed in favor of the embedded version. If production points to the embedded version, checks returnUpToDate; older production versions also revert to the embedded version.
