What's Wrong?

/ultrareview claims to review the branch but only examined uncommitted
file changes (2 files). It did not review any committed commits on the branch
despite there being 15+ recent commits.

Additionally, the one finding it produced was a false positive — it described
a bug in AuthContext.tsx:151 (single-slash typo) that does not exist in the
actual code.

What Should Happen?

## Expected Behaviour
Review all commits on the branch since diverging from main.

## Actual Behaviour
Only checked 2 uncommitted files and returned 1 false positive finding.

Actual: Only uncommitted file changes were checked (2 files reviewed,
15+ commits ignored). The one finding returned was a false positive.
