 ## Working Rule
 - This file is both backlog and handover log.
+- Future plans written in this file should be written in Korean by default.
+- When a meaningful coding/documentation task is completed, the workflow should aim to finish with a push to the git remote when the remote is available.
 - Every meaningful change should record:
   - what changed
   - why it changed

 ## Recent Change Log
+- Date: `2026-03-24`
+- What changed:
+  - Added an operating rule that future plans recorded in this repo should be written in Korean by default.
+  - Added an operating rule that completed meaningful work should aim to end with a push to the git remote when available.
+- Why it changed:
+  - The active collaboration workflow for this repository was updated so planning language and completion expectations stay explicit in the handover file.
+- How it was verified:
+  - `git diff -- TODO.md`
+- What is still risky or incomplete:
+  - Automatic push can still fail if remote auth or network state changes, so each turn should continue recording push failures explicitly when they happen.

 - What changed:
   - Stabilized the Gemini visual-review path after widened search budgets caused full-batch “no candidate thumbnails or preview frames” failures.
