… 回退；sample 接入两个包 - 新 Gradle 模块 updates/（artifact app.tinyui:tinyui-updates，与 tinyui 同版本发）：Updates 按包做 check（指针 → 掷骰 → manifest 原始字节验签 → 兼容校验 → 逐文件 sha256 下载 → staging 改名 installed）、 启动选择（重算 sha256、删过期 / rv 不匹配的 installed、清理不属于任何内置包的目录）、原子 state.json； UpdatesPage 在 installed 页面 E2 / E6 时拉黑并用内置重挂 - ECDSA P-256 验签 expect/actual：Android java.security，iOS Security.framework；真实签名夹具两端各跑一遍 - sample 加第二个包 sample-extra，Gradle 按包构建资源子目录，App 用 Updates + UpdatesPage， 从本机 http.server 拉包（Android 直连绕过宿主代理，iOS 放行本地网络） - docs：updates.md 的 UpdatesPage 签名与 current() 语义、README 目录约定按 ADR-006 加 updates/ Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Reviewer's GuideIntroduces the M3 hot-update system as a separately published KMP module, with cross-platform ECDSA verification, atomic installation and startup selection, rollback-aware page rendering, extensive tests, and a two-package sample integration validated against local OTA delivery.

摘要
本次改动新增了 updates KMP 模块、签名校验与落盘选择逻辑，并在 sample 中接入多包热更新和 UpdatesPage 回退。整体状态机和资源接入覆盖较完整。主要风险在 UpdatesPage 的回退条件未按设计限制错误类型，会将不应视为包损坏的页面错误永久拉黑已安装版本。

## Individual Comments
### Comment 1
<location path="updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt" line_range="79-82" />
<code_context>
+
+ /** Runs the check for every package at once; a second call while one is running joins it. */
+ suspend fun check(): Map<String, CheckResult> {
+ val run = checkLock.withLock {
+ inFlight ?: CompletableDeferred<Map<String, CheckResult>>().also { inFlight = it }
+ }
+ if (run !is CompletableDeferred) return run.await()
+ try {
+ val results = coroutineScope { packages.keys.map { pkg -> async { pkg to check(pkg) } }.map { it.await() } }.toMap()
</code_context>
<issue_to_address>
**issue (bug_risk):** `check()` never distinguishes the caller that created the in-flight `CompletableDeferred` from callers that joined it, because every `run` value is a `CompletableDeferred`; each concurrent caller therefore executes all package checks instead of awaiting the existing run. The single-package overload also bypasses this coordination entirely, so concurrent calls can duplicate downloads and race while replacing installed state.
**Triggers:** When two callers invoke `check()` concurrently, or when `check(pkg)` overlaps with `check()` or another `check(pkg)`.
**Suggested fix:** Track whether the caller created the deferred under the mutex, and route single-package checks through the same per-instance coordination or explicitly serialize them.
</issue_to_address>
### Comment 2
<location path="updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt" line_range="219-220" />
<code_context>
+ suspend fun check(): CheckResult {
+ val pointer = try {
+ parsePointer(fetch("$name/$runtimeVersion/$POINTER").decodeToString())
+ } catch (e: CancellationException) {
+ throw e
+ } catch (e: Exception) {
+ return CheckResult.Failed(null, FailStage.POINTER, e.message ?: e.toString())
</code_context>
<issue_to_address>
**issue (bug_risk):** Cancellation during a file fetch is rethrown without calling `discard()`, leaving the partially downloaded `staging` tree on disk. The cleanup only runs for ordinary download exceptions or later storage failures, so cancellation can leave stale artifacts until the next process startup.
**Triggers:** When the coroutine running `check()` is cancelled while `fetch()` is downloading a package file.
**Suggested fix:** Move staging cleanup into a `finally` block that runs when installation has not completed, while still rethrowing `CancellationException`.
</issue_to_address>
### Comment 3
<location path="updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt" line_range="264-269" />
<code_context>
+ }
+ }
+
+ private fun parsePointer(text: String): Pointer {
+ val root = Json.parseToJsonElement(text).jsonObject
+ val version = root["version"]?.jsonPrimitive?.content ?: throw IllegalArgumentException("current.json has no version")
+ val signature = root["signature"]?.jsonPrimitive?.content ?: throw IllegalArgumentException("current.json has no signature")
+ val rollout = root["rollout"]?.jsonPrimitive?.intOrNull ?: 100
+ return Pointer(version, rollout.coerceIn(0, 100), signature)
+ }
+
</code_context>
<issue_to_address>
**issue (bug_risk):** A present but malformed `rollout` value is silently treated as the omitted default of 100 because `intOrNull ?: 100` conflates invalid values with absence; an invalid string such as `"0"` therefore enables the update for every install instead of producing `Failed(POINTER)`.
**Triggers:** When a fetched `current.json` contains a non-integer or otherwise non-numeric `rollout` field.
**Suggested fix:** Distinguish a missing rollout from an invalid rollout and reject invalid or out-of-range values as a pointer parse failure.

*Source: betterleaks*
</issue_to_address>Sourcery assessment
Needs a human reviewer. 4 findings to address first, and this introduces a remote package trust boundary: a signed update is downloaded, persisted, selected on startup, and can replace the embedded bytecode, while page failures trigger rollback state that survives the process. If verification or selection is wrong, affected installs could run unintended remotely delivered code, and reverting the PR would not remove packages already installed or undo behavior already delivered.
Blocking findings: updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt:82, updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt:220, updates/src/commonMain/kotlin/app/tinyui/updates/Updates.kt:269, sample/js-extra/keys/demo-signing-key.pem:5
