## Process

1. Read one reference file.
2. Review the chosen scope against that reference.
3. Repeat for every reference in order.

## Output

- Emit one section per reference.

### For each section, include:

- `Reference:` the reference title.
- `Scope checked:` files and directories reviewed for that reference.
- `Result:` the findings or "No findings".

### For each finding, include:

- what is wrong
- evidence
- impact
- recommended fix
