Stash with untracked files
Tests ability to identify a stash containing untracked files. Evaluates understanding of stash -u option implications.

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'
  4. 04 echo 'Initial' > file.txt
  5. 05 git add file.txt
  6. 06 git commit -m 'Initial'
  7. 07 echo 'Tracked work' > file.txt
  8. 08 git add file.txt
  9. 09 echo 'New file' > new.txt
  10. 10 git stash -u -m 'all-my-changes'

Based on the `git stash list` output and the stash details you provided, the stash entry containing your work with the message "all-my-changes" is: **`stash@{0}`** This is the only entry visible in your stash list, and it matches both the message and the content showing tracked changes (`file.txt`) and untracked files (`new.txt` - added as a new file).

Based on the `git stash list` output and the stash details, the stash entry containing your work with the message "all-my-changes" is: **`stash@{0}`** This is the most recent stash entry (index 0) that includes both: 1. A tracked file modification (`file.txt` changed from "Initial" to "Tracked work") 2. A new untracked file (`new.txt` with content "New file") You can reference this stash entry using `stash@{0}` in commands like: - `git stash show stash@{0}` (to view the changes) - `git stash apply stash@{0}` (to apply the changes) - `git stash pop stash@{0}` (to apply and remove the stash)

The stash entry that holds **both** the tracked changes in *file.txt* **and** the untracked addition of *new.txt* is the **only** entry shown in the log: ``` stash@{0}: On main: all-my-changes ``` In Git’s stash list each line is a separate stash entry, and here there is only a single entry. It is labelled “all‑my‑changes” and is indexed as `stash@{0}`. All the changes you see in the diff (the modification of `file.txt` and the creation of `new.txt`) are stored inside this single stash entry.

nvidia/nemotron-3-nano-30b-a3b:none PASS 100% 194 in → 152 out (0 reasoning)
The stash entry you added with ```bash git stash push -m "all‑my‑changes" ``` contains **both** the tracked changes in `file.txt` **and** the newly created untracked file `new.txt`. Since `git stash list` shows: ``` stash@{0}: On main: all‑my‑changes ``` the newest stash entry – **stash@{0}** – is the one that holds “all‑my‑changes”. So the stash reference you’re looking for is: **`stash@{0}`**. (It captures the tracked `file.txt` modification and the untracked `new.txt` file.)

Based on the information provided, the stash entry containing your work with the message 'all-my-changes' is: **stash@{0}** This is confirmed by: 1. The stash list showing only one entry: `stash@{0}: On main: all-my-changes` 2. The stash details show both your tracked file changes (`file.txt` - modified from "Initial" to "Tracked work") and untracked file changes (`new.txt` - a new file with content "New file") Since there's only one stash entry with that message, `stash@{0}` is the reference you're looking for.
