Stash before merging another branch
Tests ability to recover stashed changes created before merging another branch. Evaluates stash timing in multi-operation workflows.

These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

  1. 01 git init
  2. 02 git config user.email 'test@test.com'
  3. 03 git config user.name 'Test User'

Based on the provided context and Git history, the **stash entry that contains your "main-changes"** is explicitly identified in the output as: **stash@{0}** This is confirmed by the stash list output, which shows: ``` stash@{0}: On main: main-changes ``` ### Key details: - The stash description is **"On main: main-changes"**, matching your request to identify the stash containing `main-changes`. - The parent direction in the diff (`base` → `Main change`) confirms the content of the stash matches your description. - **No other stash entries are listed** in the output, so `stash@{0}` is the only entry and the one you are referring to. ### Final Answer: The stash reference is **stash@{0}**. This corresponds to the entry labeled **"On main: main-changes"** in your `git stash list` output.
