+Ci (release): Triggering release when PR is merged into master; Test temporary files to use system temporary directory instead
+-Ci: Modify. ithub/workflows/release. yml
+-The triggering condition is changed to pull_dequest.clost to master, and only executed when merged==true
+-Retain manual triggering of workflow_ispatch
+-Change the workflow name to release
+-Upgrade pnpm/action setup to v10 and adjust the installation order to match pnpm cache
+-Test: Migration of temporary files to system temporary directory
+-All use cases use the rts tests/* subdirectories under os. tpdir() uniformly, compatible with Windows/Linux
+-Adjust file creation and cleanup to fs.rmSync (..., {recursive: true, force: true})
+-Delete the test/temp directory and related dependency paths in the repository
+-Chore (ava): Remove the exclusion of test/temp/* */*. ts in ava.cnfig.js
+-Docs (test): Update temporary file policy instructions in test/README.md

 ## Temporary Files
 
-### `test/temp/` Directory
+### System Temporary Directory
 
-All temporary test files are created in the `test/temp/` directory:
+All temporary test files are created under the system temporary directory (Node `os.tmpdir()`), e.g. `.../rts-tests/...`:
 - Automatically cleaned up after tests
-- Excluded from git tracking
+- Works across Windows and Linux
 - Used for file system tests and fixtures
 - Supports nested directory structures
 
 ### File Management
 
 Tests follow these guidelines for temporary files:
-- Create files in `test/temp/` subdirectories
+- Create files under `os.tmpdir()` with `rts-tests` prefix and subdirectories per suite
 - Use descriptive file names
 - Clean up files in `finally` blocks
 - Handle file system errors gracefully
