## WTF: {branch-name}

**Purpose:** {one-sentence description of what this branch does, inferred from commit messages}
**Base:** diverged from {trunk} at {merge-base-short} ({N} commits ahead)
**Scope:** {files changed} files | +{insertions} -{deletions}

### Changes

- {2-5 bullets summarizing logical changes, grouped by concern}

### Key Files

| File   | Change | What                   |
| ------ | ------ | ---------------------- |
| {path} | +n/-n  | {one-line description} |

## WTF: {trunk-branch}

{N} commits in the last 7 days.

### Highlights

**{Day}**

- {hash} {summary} ({author})

### Filtered Out
