[A02-1] [LOW] Empty misnamed contract ErrFLow in ErrFlow.sol

[thedavidmeister]

Description

src/error/ErrFlow.sol:21 declares an empty contract:

contract ErrFLow {}

It is:

• A typo (ErrFLow vs the file name ErrFlow.sol).
• Empty — has no fields, functions, modifiers, or inheritance.
• Unreferenced anywhere in src/ or test/.

Compiling this file produces an empty contract artifact whose only purpose is to confuse readers into thinking errors must be inherited from it. Free-floating errors (the rest of the file) do not require a host contract and the surrounding declarations confirm none is intended.

Location

src/error/ErrFlow.sol:21

Proposed fix

Remove the empty contract:

-contract ErrFLow {}
-
 /// Thrown when burner of tokens is not the owner of tokens.
 error BurnerNotOwner();

Fixed in 70294f4: empty contract ErrFLow {} deleted from src/error/ErrFlow.sol. Build/full-suite/static all exit 0 after the change.

Reopened: fix is committed on branch 2026-04-27-audit-triage but not yet merged. Will close when the PR lands.
