Credence.Pattern.NoDocFalseOnPrivate (credence v0.4.0)

Style rule: Detects @doc false placed before private functions (defp).

Private functions cannot have documentation — the compiler ignores @doc on defp entirely. Adding @doc false is redundant noise that misleads readers into thinking it's suppressing something.

Bad

@doc false
defp helper(x), do: x + 1

Good

defp helper(x), do: x + 1

# If you want to hide a public function from docs:
@doc false
def internal_api(x), do: x + 1
