Walkthrough
The changes add resumable rootfs activation and synced version-marker publication. They also update lock publication, special-file conversion, privileged updater cleanup, and descriptor handling. Other changes adjust recurrence positions, notification routing, pet drag behavior, and install failure guidance.
The installer checks an existing unmarked rootfs against the current APK payload and finishes activation when compatibility checks pass. Integration tests cover resume and cases that remain on the normal install route.
Synced runtime version publication app/android/app/src/main/kotlin/io/github/ccch1mneyyy/dsh_app/runtime/EngineUpgrade.kt, app/android/app/src/main/kotlin/io/github/ccch1mneyyy/dsh_app/runtime/RuntimeInstaller.kt, app/android/app/src/test/kotlin/io/github/ccch1mneyyy/dsh_app/runtime/RuntimeDurabilityTest.kt
Runtime recovery and rootfs activation publish the version through a synced temporary marker and atomic replacement. Durability tests check sync ordering and publication failures.
The installer removes matching stale staging directories before creating a new install directory. Tests cover removal and preservation of specified entries.
Snapshot and APK descriptor closure app/android/app/src/main/kotlin/io/github/ccch1mneyyy/dsh_app/update/privileged/PrivilegedSelfUpdater.kt, app/android/app/src/main/kotlin/io/github/ccch1mneyyy/dsh_app/update/privileged/SelfUpdateInstallerService.kt
snapshot closes its source and destination descriptors, and the installer service closes the raw APK descriptor in a finally block.

Recurrence patch and tests runtime/patches/rrule-negative-position-range.diff, runtime/patches/pins.json, runtime/patches/series, runtime/tests/rrule-negative-position.test.mjs
The patch skips out-of-range set positions. Tests cover positive and negative positions, occurrence counts, and resolution.

Summary
Status notification route fallback app/android/app/src/main/kotlin/io/github/ccch1mneyyy/dsh_app/notify/ChatNotifier.kt
When no post is supplied, actionStatus uses the matching active notification’s existing content intent if available.
The comments and failure message state that the phone may have updated despite an install command failure and direct the operator to check the installed build before retrying.
ccch1mneyyy/dsh-Go#974: Both PRs change rootfs recovery and compatibility checks in the install path.
ccch1mneyyy/dsh-Go#1119: Both PRs change how runtime compatibility checks locate metadata files.
Merge Risk: Low · up to 724b3
The change fixes several interrupted-operation recovery problems. Two earlier concerns remain open: a rare power-loss window during runtime install, and a possible cleanup race between concurrent self-update workers. Both are bounded, so the change can be merged with owner awareness.

Explanation
The title names the fix batch ('2026-11 重构第十三批') and lists several changes: empty lock and marker left by interruption, self-update leftovers, timed rules, Web slash menu and presets, floating pet, and notifications. The changeset covers the lock and marker recovery, self-update cleanup, rrule negative-position fix, floating pet, and notification changes. Its count does not match the objectives, which list eleven fixes while the title says fifteen (十五处). The title also mentions a Web slash menu and presets, which do not appear in the changed files. The title is therefore partially related: the main themes are present, but it includes an unsupported item and a wrong count. It is also long at 77 characters.
Resolution
Rewrite the title to describe the main change in one short sentence, in a language consistent with the repository. Remove items that are not in the changeset, such as the Web slash menu and presets. Correct the count to match the actual number of fixes, or drop the count. Example: 'fix(runtime): prevent empty lock and marker files after interrupted runs'.

Minor · Data Integrity & Integration · Quick win
Sync the extracted payload before the rootfs rename.
Extraction writes payload files without syncing them. activateRootfs renames staging to rootfs before the first data barrier, which is the sync() call in finishRootfsInstall. After a power loss in that window, the marker-less rootfs passes the new resume check. finishRootfsInstall then publishes rootfs.version for payload data that may be missing or truncated. Re-extraction does not run in that case.
Call the existing sync() after extraction completes and before activateRootfs renames staging. Keep the sync() call in finishRootfsInstall, because it still covers the restored kept files.

Cleanup can delete an active installation's staging file.
cleanupSelfUpdateDirectories removes every directory whose name matches dsh-self-update-<UUID>, and deletes its base.apk. It does not check whether a worker still uses the directory. If a second helper worker starts while another worker is copying base.apk, the first installation can fail at Os.chmod(file.path, 256) or during later path-based steps. The per-object busy guard and the per-process globalGuard do not prevent this, because they do not cover a second worker process.
Remove only directories that no live worker uses. Track ownership of the staging directory, or skip the cleanup while another worker is active.

做了什么
2026-11 重构线第十三批：十五片修复，都是进程中途被杀、文件描述符泄漏这类收尾问题。只改 Kotlin、Node helper 脚本和开发脚本，外加五条小引擎补丁：三条改 rrule 库（5557、5558、5559），一条改 Web 输入框的斜杠菜单（5564），一条改 Web 预设设置（5565）；pins 只新增这五条。每片一个提交，可单独回退。
FileInputStream(FileDescriptor)/FileOutputStream(FileDescriptor)关流时不关传入的原始 FD（AOSP 源码已核），Os.open打开的 FD 一直挂着，被删掉的整个 APK 继续占空间，多次累积。主要在PrivilegedSelfUpdater（应用进程里，每次泄漏两个 FD）。Os.open后在finally里Os.close。createNewFile之后、写 PID 之前被杀，留下空锁；原生、安全模式 helper、上游引擎三方都不接管空锁，之后永久锁死。SafeMode.kt里的 Node 脚本）同样是先wx建锁、再写 PID，中途被杀留空锁。wx、0600），再symlinkSync发布。mkfifo后再ln，可能产生指向 FIFO 的 tawcroot 链接；之后关掉 tawcroot 或做保留式重置，还原时Files.copy去读这个 FIFO，没有写端就永远卡住，启动跟着卡死。home.carry/rootfs.old的，一律走原路线。rootfs 是先解到临时目录、完整后才改名的，所以「目录在、标记缺」只可能是完整解包之后。File.writeText，创建或截断之后、写正文之前被杀，留下空标记（5551 有意不把空标记当成缺失）。EngineUpgrade已有的原子写（写.next、sync、ATOMIC_MOVE、目录 sync）。daemon(true)，应用退出不会带走它）在复制、校验时因重启、低内存或 Shizuku 停止而被杀，runInstall的finally没执行，/data/local/tmp/dsh-self-update-<UUID>/base.apk留下；下次换新 UUID，旧的永远不回收。runInstall开头、建本次目录之前，扫一遍dsh-self-update-<UUID>目录，不跟随符号链接，只删普通文件base.apk和随后变空的目录；任何一步失败都忽略，不影响本次安装。daemon 只有一个，忙碌门保证同一时间只有一次runInstall。正常的 APK 解析路径不变。onDragStart末尾那句无条件的fitFrame()按拖动姿势先把窗口收窄，旧画面被裁掉一块，直到拖动图加载出来。react("drag")→tick→onShown已经调过fitFrame；没缓存时图到了redraw→onShown再调。PetFramesTest、FrameClockTest、EdgeSnapTest44 个方法全过（43288254598）。post == null），换出来的失败提示通知丢了contentIntent，点正文回不到原会话。contentIntent（NotificationManager.getActiveNotifications，API 23 起）；有会话信息照旧。完整 CI 43303343689 九项全过。FREQ=MONTHLY;BYDAY=MO;BYSETPOS=-5），而某个月不够 N 个（四月只有四个星期一）。rrule 库里slice(-5)[0]会被夹到当月第一个星期一，算出一个错误的日期并消耗一次计数。rrule-negative-position-range.diff（一行，作用于锁定版本的node_modules/rrule/dist/es5/rrule.js）：位置超出当期候选数就跳过这一期。新增runtime/tests/rrule-negative-position.test.mjs六例，调用真实的dsh-util-time解析和计算。pins 新增这一条，既有条目不变。完整 CI 43313724105 九项全过，六例全过。FREQ=WEEKLY;BYDAY=MO,…,FR;BYSETPOS=2），而开始那天不是一周的第一天。rrule 库第一周从开始那天截断后再排位置，取到的不是这一周真正的第 N 个。rrule-weekly-first-period.diff（5 行）：带BYSETPOS的按周规则，第一周先把游标退回一周起点（WKST）再排位，结果仍由原有的开始时间下界过滤。新增runtime/tests/rrule-weekly-first-period.test.mjs六例。作者第一版还改了库里三个共享日期函数（只为公元 100 年这种情况），没收。和 5557 改同一个文件，pins 按series顺序重录。BYDAY同时写了普通星期和带序数的星期（如FREQ=MONTHLY;BYDAY=1MO,TU，每月第一个周一加每个周二）。rrule 库把两类当成交集，几乎算不出候选，Host 建任务时报 not_future。rrule-mixed-byday.diff（3 行）：按 RFC 5545 改成并集；其他BY*仍取交集。includes对 null 安全、nwdaymask恒为数组，没有新的空值路径。新增runtime/tests/rrule-mixed-byday.test.mjs九例。三条 rrule 补丁改同一个文件，pins 按series顺序重录。单独完整 CI 43331754964 九项全过。/时，技能列表请求一次普通失败，技能组被移出菜单，命令组让菜单继续开着；之后再输入/p，技能请求成功也找不到组，结果被丢，菜单里一直没有技能（关掉菜单重开可恢复）。input-trigger-source-recovery.diff（改dsh-client-ui-input-trigger/lib/client.js一个条件）：新查询发现已注册来源缺组时，用已有的seedGroups重建本次分组；分组完整时保留原高亮，不加状态和重试。新增runtime/tests/input-trigger-source-recovery.test.mjs四例。单独完整 CI 43346286355 九项全过。load()用??=复用了那次迟到的读取，按旧默认同步空白会话，首条消息仍用旧预设（手动选一次可恢复）。web-preset-save-freshness.diff（改dsh-client-ui-agent-preset/lib/client.js两行）：写完先等在途的this.loading再重新读取；只有新名单ready时才同步空白会话。不加状态、计时器和重试。新增runtime/tests/web-preset-save-freshness.test.mjs五例。单独完整 CI 43350973021 九项全过。tooling/dev-run.sh里adb install返回非零，但 USB / Wi-Fi 中断时安装可能已经成功、只是回执丢了。原提示说「设备上什么都没改」。5552 依赖 5551。5548 和 5553 是同一个锁的两侧，一起合两边规则一致；上游引擎「先
open(wx)再写 PID」的空锁窗口仍在，这两片没有堵它。验证
da7c0881上跑过：SelfUpdateStreamsTest、SelfUpdateRecoveryTest、PrivilegedSelfUpdaterPersistenceTest、SelfUpdatePolicyTest、SelfUpdateArgumentsTest、ApkInstallerFailureTest共 34 个方法全过；tooling/test_dev_run_*.py10 例全过。LastKnownGood*、TawcrootLinks*、RuntimeUpgrade*、RuntimeDurabilityTest、EngineUpgradeTest等九个类 74 个方法全过；5553 的 Node 三例通过。没验证的
.dsh-lkg-lock-*.pid这类隐藏小文件，没有回收，但不挡任何操作。/proc/self/fd/N，CI 验证不了，已退回；本 PR 收的是改成「安装前清孤儿」的版本，正常路径不变。完整 CI 43283284049 九项全过，SelfUpdateTempFilesTest等七个类 35 个方法全过（43283352036）。旧 helper 中断后的回收没有在设备上实测。companion_room_guard_test.dart:195、companion_voice_test.dart），重跑失败 job 后通过。
