## What it does

**A single-file change to index.test.ts, 2 lines.**

1 file changed across 1 area of tailwindlabs/tailwindcss, 1 added and 1 removed.

The last CI run on main was on July 16, and the last globby release (16.2.2) was released on July 15 (~21 hours earlier).

**Diagram: Where the change landed. Node size is not to scale; the line counts are exact.**

- tailwindcss (1 files, 2 lines) [accent]
- Tests (1 file, 2 lines) [good]
- index.test.ts (+1 −1) [bad]
- tailwindcss -> Tests
- Tests -> index.test.ts : heaviest

- **Heaviest file.** integrations/upgrade/index.test.ts, +1 −1, which is 100% of the change.
- **Tests moved with it.** 1 test file changed alongside 0 source files.
- **Spread.** 1 files, 2 changed lines in total.

## How it works

**The largest single edit is in index.test.ts.**

Quoted verbatim from the diff. This is the biggest hunk by changed lines, which is where a reviewer's attention usually belongs first.

```typescript
@@ -2557,7 +2557,7 @@ test(
         @import './utilities.css';
         @import './generated/ignore-me.css';
       `,
-      'src/generated/.gitignore': `
+      'src/generated/.gitignore': txt`
         *
         !.gitignore
       `,
```

_integrations/upgrade/index.test.ts, +1 −1. The largest hunk in the largest file._

## File map

**Every file this change touches, heaviest first.**

Role is inferred from the path and risk from the path and the line count. Neither was read from the code.

| File | Role | Change | Risk |
| --- | --- | --- | --- |
| `integrations/upgrade/index.test.ts` | test coverage | modified, +1 −1 | low |

## Receipts

**Where each number above comes from.**

All of it is arithmetic over the file list and the check results, so it can be recomputed from the source.

## Merge order

**A reading order for the review, not a deployment plan.**

Ordered by how expensive each part is to get wrong, which is a structural property rather than an informed one.

1. **Then index.test.ts.** The largest single file in the change, +1 −1.
2. **Finish with the tests.** 1 test file changed. Reading them last tells you what the author believed they were changing.

## What this brief could not check

- No language model read this change. Every statement here is computed from file paths, line counts, and CI status, so it describes the shape of the diff and not what the diff means.
