## Mode

READ_ONLY_SMALL_FIX.

No direct source edits. Produce one minimal patch artifact under ProjectIntakeTower.

## Fix class

{fix}

## Constraints

- One small fix only.
- Must have root-cause note before patch proposal.
- Must include verifier command.
- No refactor.
- No dependency install.
- No commit/push/merge.
- If unclear, mark needs_human.

## Suggested verifier

```bash
cd {row['path']}
{cmd}
```

## Required output

- Report: `small_fix/reports/{slug(row['path'])}_small_fix_report.md`
- Patch artifact: `small_fix/patches/{slug(row['path'])}_small_fix.patch.md`

## Root-cause note

TODO(worker): explain why this small fix is needed from observed repo/doc/test evidence.

## Proposed minimal fix

TODO(worker): one small, bounded fix only.

## Patch artifact

See matching file in `small_fix/patches/`.

## Verifier

```bash
cd {row['path']}

## Safety

No source files were changed by this intake artifact.
