⚠️ Potential issue | 🟡 Minor

\x1B[3J clears terminal scrollback history.

The PR description states the goal is to "preserve terminal scrolling" and avoid forcing scroll, but \x1B[3J explicitly erases the scrollback buffer. If the intent is only to clear the visible screen and reposition the cursor, drop the \x1B[3J sequence and keep only \x1B[2J\x1B[H. Same applies to Line 32.

🤖 Prompt for AI Agents 
In `@src/core/view.ts` at line 27, The code currently clears the terminal
including scrollback by writing '\x1B[3J' in the process.stdout.write calls;
update both occurrences in src/core/view.ts (the process.stdout.write(...) calls
that build the clear sequence) to remove the '\x1B[3J' token so the sequence
becomes only '\x1B[2J\x1B[H' + output, thereby clearing the visible screen and
repositioning the cursor while preserving terminal scrollback.

}
} catch (error) {
// Clear screen and show error prominently

ANSI stripping mismatch

These assertions use allOutput (raw, potentially ANSI-colored) while the new lines array is stripAnsi’d. If chalk color output is enabled in the test environment, expect(allOutput).toContain('Draft Changes') / similar can fail due to escape codes splitting the plain text. Use the stripped version (lines.join('\n') or stripAnsi(allOutput)) consistently for substring assertions.


// Completed section should only contain changes with all tasks done
expect(output).toContain('Completed Changes');
expect(output).toContain('completed-change');

expect(allOutput).toContain('completed-change');
