 Outcome:
 - Cloud repository `master` was synchronized to `62b6a62ac5c9b50f7a236a409128d2738430b6be`.

+## 2026-06-26 18:27 EDT - backup directory files sync closure
+
+User request:
+- Submit all files under the backup directory.
+- Complete any unclosed loop and push to the cloud repository.
+
+Process:
+- Checked repository status:
+  - branch `master` aligned with `origin/master`.
+  - untracked backup note file:
+    - `备忘/备忘3.txt`
+  - unrelated deletion visible:
+    - `linuxcnc.zip`
+- Searched backup-like directories:
+  - `/home/meswork/cnc_wams/textbak`
+  - `/home/meswork/cnc_wams/备忘`
+- Checked tracked files:
+  - all `textbak` files were already tracked.
+  - `备忘/备忘1.txt` and `备忘/备忘2.txt` were already tracked.
+  - `备忘/备忘3.txt` was untracked and is the missing backup-directory file to submit.
+- Inspected `备忘/备忘3.txt`:
+  - size: 1027 bytes.
+  - content mirrors the working5 gmoccapy_XYZAB task request.
+- Confirmed remote:
+  - `origin http://154.8.160.151:3000/wangdequan/cnc_wams`
+- Fetched remote and checked divergence:
+  - `git fetch origin`
+  - `git rev-list --left-right --count origin/master...HEAD`
+  - result: `0 0`
+- Ran whitespace check for targeted paths:
+  - `git diff --check -- textbak 备忘 web-rtcp-5axis-sim-plan/gptlog-process/gpdlog.md`
+  - passed.
+
+Decision:
+- Stage and commit `备忘/备忘3.txt` and this process log.
+- Do not stage `linuxcnc.zip` deletion because the user asked for backup-directory files, and the zip deletion is outside that scope.
+
+Outcome:
+- Pending commit and push at the time this entry was written.
