title: "Manual Test: quarto_ipynb accumulation during preview (#14281)"
format: html
execute:

## Purpose

This document tests that `.quarto_ipynb` files do not accumulate during
`quarto preview`. Before the fix, each save during preview created a new
numbered variant (`test.quarto_ipynb_1`, `test.quarto_ipynb_2`, etc.)
that was never cleaned up.

**Why manual?** Preview re-render behavior requires an interactive session
with file-save events that cannot be triggered in automated smoke tests.

## Steps

1. Run: `quarto preview tests/docs/manual/preview/14281-quarto-ipynb-accumulation.qmd`
2. Wait for the preview to open in the browser
3. Edit this file (e.g., change the text below) and save 3-4 times
4. Check this directory for `.quarto_ipynb` files

## Expected

- Only one `14281-quarto-ipynb-accumulation.quarto_ipynb` file should exist
  at any time during preview (no `_1`, `_2` suffixes)
- After stopping preview (Ctrl+C), the `.quarto_ipynb` file should be cleaned up

## Code cell

```{python}
1 + 1
```

Edit the line below to trigger re-renders:
